Description

Multifunctional combined braking system device

The invention relates to a hydraulic brake system device for a two-wheeled vehicle, in particular to a multifunctional combined brake system device for a bicycle and a motorcycle hydraulic brake system.

The most common hydraulic disc brake system for two-wheeled vehicles in the past is (1) Left and right hands separately brake the front or rear wheels (Single-hand brake single wheel, hereinafter referred to as (1) SBS). In recent years, (2) one hand brakes the front wheel and the other hand brakes the front and rear wheels at the same time (called Combined Brake Systems in the European Union) for driving safety, hereinafter referred to as (2) CBS. Or (3) “Always Two Brake” (Always Two Brake hereinafter referred to as (3) ATB device) that can brake the front and rear wheels at the same time when either hand is braked by either hand. , The rider will subconsciously squeeze the brake grip with both hands urgently. As a result, the front wheels are often braked first, so rollovers often occur. Even the more modern (2) CBS and (3) ATB have the risk of the front wheels being braked first. opportunity.

The above two known (2) CBS or (3) ATB brake systems, based on the patents or product information collected now, such as CN I 600563, are mechanical left and right hands that can brake the front and rear wheels at the same time, and are converted by driving a hydraulic pump. The hydraulic brake function of simultaneously braking the front or rear wheels (ATB), and the inventor’s own application (application number 107122051 invention patent), the same case has obtained an innovation patent (application (Patent No. 107208619), although they can fully share the (2) CBS function played, the disadvantage is that the same two-wheeled vehicle can only have a single braking system at the same time.

The conventional two-wheeled vehicle brake system functional products are already installed on the bicycle when buying the bicycle, such as the traditional one-handed independent braking of the front or rear wheels (1) SBS, or the purchase of more modern ones (2) CBS or A bicycle with (3) ATB function will always use the special (1) SBS or (2) CBS or (3) ATB brake function bicycle without any choice. If you want to change (1) SBS bicycle to (2) CBS or (3) ATB or change (3) ATB to (2) CBS function brake system, you can only purchase (2) CBS or (3) ATB to replace the original one-hand brake system ( 1) SBS. Even if a joint brake device with other functions is purchased separately and installed on an existing bicycle, it is still a bicycle with a single brake function. The same goes for buying a new car, only one type of braking system is available. This kind of bicycle with a single braking function is a great pity for riders who want to increase the fun of riding in a progressive society. More importantly, whether it is (1) SBS or (2) CBS or (3) ATB, when braking, there will be momentary front wheels braking first, rear wheels braking dangerously, especially in (1) SBS and (2) ) When CBS brakes, one hand is to brake the front wheel alone. In (3) ATB, the front wheel is braked with one hand and then the rear wheel is braked. It does not improve the conventional single-brake front wheel, which is prone to lock the front wheel and roll over. The inventor is here When testing the disc brake function, at a speed of 25 kilometers per hour, the front wheel was braked separately and a rollover event occurred. It has always been a dream for knights to brake the front wheel first and roll over. Therefore, the European Union requires ABS with anti-lock braking or (2) CBS and (3) ATB with combined braking. But (2) CBS and (3) ATB only solve half of the safety problem: when one hand brakes the front wheels and the rear wheels at the same time, there are advantages of the rear wheels braking first, and the front wheels rear braking, but when the other hand brakes the front wheels alone, it will still be as traditional (1) The sudden brake front wheel rollover incident occurred in SBS.

For professional riders, under different road conditions or different riding purposes, such as outings, long-distance road racing, mountain climbing, etc., especially when riding downhill, the front wheel should not be braked first, so This is why ATB is popular in Europe (3).

In known brake systems for two-wheeled vehicles. Although it has been improved to the more advanced (2) CBS and (3) ATB safe braking functions, there is still an unsafe point in (2) CBS has the right hand (or left hand) function to brake the front wheel alone, braking alone The front wheel, as mentioned above, is a two-wheeled vehicle, especially a lighter weight bicycle. It is easy to cause a rollover event when the rear wheel is still rotating during sudden braking. Therefore, to avoid sudden braking on the front wheel, it is best that the front wheel can produce The safety braking trilogy of slow braking, slowing down, and then braking. The text description seems to be very long. In actual braking, it is a safe braking program that is fully automatic and completed in less than one second according to the program. The above is as if the inventor won the M402254 patent for innovation gold medal in 101 (this innovation patent is absolutely eligible to obtain an invention patent, because in the technical report, click item 6: no identical previous documents were found, because of a hurry Only apply for innovation) in the mechanical braking system, there is a trilogy of braking function (3) (ATB): when the vehicle speed is more than 4x kilometers, any hand brake , Can safely stop the bicycle or motorcycle smoothly.

In view of the above theme, the main purpose of the present invention is to provide a comprehensive brake control mechanism for two-wheeled vehicles, especially bicycles, as mentioned in the [Prior Art]. And rear wheels (1) SBS, and (2) the right hand (or left hand) brakes the front wheel, the left hand (or right hand) brakes the rear wheel and the front wheel at the same time (2) CBS) and (3) the left and right hand can brake at the same time (3) ATB) for the front and rear wheels, and (4) the trilogy of safe braking that slows down, slows down, and then brakes the front wheels, which is known to have failed to find a solution, and can quickly return the oil at the same time. Relax the front wheel (4) unidirectional flow adjustment module, etc., three braking systems plus a slow braking function, integrated into a brake controller, convenient for riders to install at one time, there are always three braking systems, one slow braking function is available . Combining the above braking functions into a hydraulic brake "multi-functional combined braking system device" in one controller, so that consumers who purchase a multi-functional combined braking system device can make a single purchase, always at any time, any road condition, and any place Easily choose and enjoy any one of the three most suitable riding methods with braking function. Function (4): The front wheel slowly rises and the braking force can quickly return to the oil. The relaxed front wheel is embedded in the oil circuit of the multifunctional combined braking system. When any one involves the front wheel braking, it can produce the front wheel first slow braking, The safety brake trilogy of slowing down and then braking requires no choice. When braking the front and rear wheels at the same time, the rear wheels are always braked first, and the front wheels are braked back. This is also one of the advantages of the concept of the present invention.

According to an embodiment of the present invention, in order to achieve the above purpose, a multifunctional combined braking system device; its shell structure is in any geometric shape, such as round, square, flat, polygonal, and it is designed mainly according to the installation location and aesthetics. Appropriate appearance, such as the appearance of a bicycle faucet, etc.: The hydraulic hand enters a hydraulic cylinder from the left and right ends of the multifunctional combined braking system device. There is a piston mechanism in the hydraulic cylinder, which separates the hydraulic cylinder into two independent left and right sides. The oil grooves become two independent hydraulic brake oil circuits. If any oil circuit has a problem, there is another oil circuit for braking, which can guarantee the brakes: a function selection mechanism, which passes through the hydraulic cylinder from the top of the housing and passes through the piston The function slot is inserted into the supporting point pivot seat at the bottom of the housing. A piston mechanism divides the hydraulic cylinder into two left and right oil grooves, each with a check mechanism at both ends, and the left and right oil grooves are respectively provided with oil pipes leading to the front wheel and the rear wheel hydraulic brakes. At the front end of the front wheel oil pipeline, there is a (4) one-way flow adjustment module, which constitutes the multifunctional combined braking system device of the present invention.

According to an embodiment of the present invention, this section describes the structure of the piston mechanism; the piston mechanism is provided with a first spacer ring, a second spacer ring, a third spacer ring, and a fourth spacer ring at each of the left and right ends. The first oil seal is placed on the first spacer ring. Between the first and third spacer rings, the second oil seal is placed between the second and fourth spacer rings. The first oil seal and the second oil seal are opposite to each other. The hydraulic oil when braking is The left and right oil pipes enter the oil groove respectively, and compress to the middle of the piston mechanism. Therefore, the oil cover of the left and right oil seals must face the oil inlet direction to the left and right to resist the pressure generated by the hydraulic oil. The third spacer ring and the fourth spacer ring are separately placed at the outermost end of the piston rod to prevent the oil seal from being separated from the piston rod. There is an oil seal shaft between the first spacer ring and the third spacer ring, and between the second spacer ring and the fourth spacer ring. The seal is sleeved on the oil seal shaft.

According to an embodiment of the present invention, this section describes the functional groove structure; in the piston mechanism, the intermediate part between the first spacer ring and the third spacer ring is called the piston rod, and there is a set of functional grooves in the axial and longitudinal center of the piston rod. The hollow long groove penetrates the piston rod from the inner surface of the first spacer ring to the second spacer ring, and is called (3) ATB groove; There is an elliptical groove with a width larger than that of the hollow long groove, which can penetrate the piston rod vertically. The elliptical groove is used to coordinate with the slow pressure rise of the front wheel when braking. It extends a short length from the longitudinal center point to the right without extending to the left. It is (1) SBS slot. At the same time, in the upper layer with the same center point as the elliptical groove (1) SBS groove, there are short grooves with the same diameter, same width, and shallower depth overlapping the upper layer of the elliptical groove, the starting point of the right end is the same as the elliptical groove, and the other end extends to the left end of the piston rod The first spacer ring, called (2) CBS groove, has a shallow depth (for example, 0.3 cm deep and 0.6 cm wide, depending on the design, it is only an example and not limited to this). The arrangement sequence of the grooves is the short groove (2) CBS groove is coaxial with the piston rod, the first layer is close to the surface of the piston rod, and then the elliptical groove with the same center (1) SBS, the two short grooves and the elliptical groove are the same The center and the grooves of the same width are simultaneously divided into two axially by the narrow hollow long groove (3) ATB groove (for example, 0.3 cm wide, but not limited to this, the purpose is to make it easier for the reviewer to understand) Half, these three grooves constitute one of the key points of the multifunctional brake. Its function is to allow the positioning column in the function selection mechanism to extend into the function groove. The depth of the extension is different, and the left and right movement lengths of the piston mechanism are allowed to be different to produce different braking functions. This is one of the conceptual features of the present invention.

According to an embodiment of the present invention, the third and fourth spacer ring ends at the outermost end of the piston rod On the left and right, there is a first and second cylinder with a smaller diameter than the spacer ring. The diameter matches the inner diameter of the compression spring. It is called a spring seat. Its function is to put the compression spring in the backstop mechanism on the spring seat. The outer edge is positioned, and at the same time, in the axial part of the center of the left and right spring seats, there is a bottomed round hole called the check spring hole seat. The check spring is tightly inserted into the spring hole seat, so that the check spring follows the piston Move left and right will not detach.

According to an embodiment of the present invention, there is a set of check mechanism wrappers at the left and right ends of the piston mechanism; a compression spring, a check valve spring, a check valve shaft and an O-ring are formed. The O-ring sleeved on the check valve shaft has an O-ring seat on the same centerline as the piston mechanism adjacent to its front end. The O-ring seat is a trumpet-shaped hollow cone, and the bottom has a flat surface with a diameter slightly larger than the O-ring. Outer diameter, there is a circular hole in the coaxial center of the O-ring seat for the passage of hydraulic oil to the oil tank. The diameter of the passage is slightly larger than the check valve shaft, allowing the front end of the check valve shaft to be inserted and running back and forth freely. Allow the flow of hydraulic oil to be unhindered during braking or backflow, and at the same time, when the O-ring on the check valve shaft is pressed against the bottom of the O-ring seat, a backstop effect is generated to seal the passage of flow.

According to an embodiment of the present invention, the check mechanism; in this embodiment, a check valve spring, a check valve shaft covered with an O-ring and an O-ring seat are used to achieve compression when the closed oil pressure The oil passage connecting the hand and the oil groove of the piston mechanism opens the closed oil passage immediately when the oil pressure hand is released, facilitating the return of the hydraulic oil to the check mechanism of the oil groove of the oil pressure hand. However, it is not limited to this. Anything that can be used in the oil circuit connecting the oil pressing hand and the oil groove of the piston mechanism. The oil circuit, and other check valves that facilitate the oil groove of the piston mechanism to lead to the hydraulic hand function, are all included in the patent scope of the concept of the present invention.

According to an embodiment of the present invention, the compression spring of the check mechanism is in a compressed state, one end is sleeved on the spring seat of the piston end, and the other end is close to the outer shell of the O-ring seat at the end of the hydraulic cylinder Surface, the compression springs at the left and right ends of the piston mechanism balance the piston mechanism in the middle of the hydraulic cylinder. When it is braked, it moves left and right with the brake pressure. When there is no brake pressure, it returns to the middle balance position. This compression spring It can be cylindrical or a conical spring with a large end and a small end.

According to an embodiment of the present invention, a check valve spring is planted in the check mechanism, which is coaxially placed in the compression spring, one end is inserted into the check valve spring hole seat, and the other end is sleeved with the short shaft end of the check valve shaft: The check valve shaft has a spacer ring with a larger outer diameter than the check valve shaft, which divides the check valve shaft into two sections. The short check valve shaft end is sleeved into the front end of the check valve spring, and the spacer ring serves as the dead point: one The O-ring is sleeved on the long shaft end of the check valve at the front end of the spacer ring, and supported by the spacer ring, the long shaft end of the check valve shaft extends into the channel connected by the O-ring seat, and at the same time makes the O on the check valve shaft The bottom surface of the ring and the O-ring seat is balanced by the compression spring, so that a certain gap is maintained: when the first hydraulic hand or the second hydraulic hand is not actuated, the hydraulic oil can smoothly pass through the channel and the O-shaped The ring seat and the check valve shaft are connected to the oil groove in the hydraulic cylinder.

According to an embodiment of the present invention, the hydraulic cylinder is divided into a first oil groove and a second oil groove by a piston mechanism. When the first hydraulic hand or the second hydraulic hand is pinched to generate brake pressure, the hydraulic oil passes through the channel It is pressed into the first oil groove or the second oil groove in the hydraulic cylinder through the O-ring seat, the piston mechanism is pushed to the other side without pressure, and the shrinking spring of the other side is compressed to make it shorter. At the same time, the check valve spring in the compression spring, Immediately push the check valve shaft and the O-ring to move forward, against the channel port, the check valve spring is compressed, the pressure generated by the check valve shaft is pressed against the O-ring in front of the spacer ring The bottom surface of the O-ring seat has the function of sealing the passage. The hydraulic oil pressure in the first oil tank or the second oil tank in the hydraulic cylinder rises, and the hydraulic oil is pressed into the front or rear wheel oil pressure through the third or fourth oil pipe on the wall of the hydraulic cylinder The brake produces a braking function. When the first hydraulic hand or the second hydraulic hand is released, the piston mechanism returns to the central equilibrium state, the channel at the bottom of the O-ring seat is opened, and the hydraulic oil returns to the connected hydraulic hand oil groove. Because the hydraulic oil in the hydraulic cylinder is separated by the piston In the first oil tank and the second oil tank, so the first oil pressure hand, the first oil pipe, the first oil tank, (4) the one-way flow adjustment module, the third oil pipe and the disc brake connected to it form an independent The hydraulic brake system is an independent hydraulic brake system composed of the second hydraulic hand, the second oil pipe, the second oil tank, the fourth oil pipe and the rear disc brake connected to it. The two closed hydraulic brake systems are not connected. Hydraulic brake system, so the hydraulic oils in the two hydraulic brake systems are not mixed during the braking action. At the same time, if an accident occurs in either system, such as an oil leak, the other system can continue to operate safely.

According to an embodiment of the present invention, this section describes (4) one-way flow adjustment module; there is a (4) one-way flow adjustment module between the first oil tank and the third oil pipeline, and the (4) one-way flow adjustment module Function When the front wheel is braked in an emergency, the hydraulic oil pressed into the front wheel brake by the hydraulic hand will reduce the flow. The braking effect of the brake is slowly increased, instead of the conventional rapid increase, which may cause the front wheel to lock and roll over. danger. This action mostly occurs during emergency braking in an accident. The rider will subconsciously squeeze the left and right oil pressure hands with both hands at the same time, and the distance between the front wheel brake and the oil pressure hand is shorter than the distance between the rear wheel and the oil pressure hand. More than 2 times, less turns and less pressure loss, so most of the front wheels will brake first, and then the rear wheels will brake. Although the difference is very short, the time of an emergency braking is about 0.5 seconds, and a vehicle speed is 30 per hour. At kilometer, the wheel rotates about 8.33 meters per second (4.16 laps/sec). If the braking time of the front and rear wheels differs by 0.1 second, it means that the front wheels are locked and the rear wheels are still turning 0.416 laps (about 0.83 meters, the circumference of the wheel). 2 meters), enough to lift the rear wheel and cause a rollover accident. In order to avoid the above-mentioned accidents, the present invention installs a (4) one-way flow adjustment module between the first oil tank and the third oil pipe connected to the front wheel. The brake difference is not felt during slow braking. When braking, the hydraulic oil flow to the front wheels is reduced, and the time for the hydraulic oil to fill the brake pistons of the front wheels is delayed, so that the front wheels can be compared to the rear wheels. That is to say, the front wheels have not been fully braked and locked, and the rear wheels have been locked due to functional grooves. (1) SBS groove, the piston mechanism moves one to the left The rotation of the rear wheel that produces light braking for a short distance decelerates, causing the front wheel to drag the rear wheel to walk in a straight line, just like the sled principle; this theory has been applied in the patent M402254, and a very safe braking effect can be obtained. However, when the brake is released and the oil is returned, the immediate oil return speed will not be affected, so that the front wheels are immediately in a non-braking state, so as not to affect the driving. This function is used in (1) SBS and (2) CBS braking to prevent the shortcomings of the front wheels from locking up quickly. In (2) CBS braking, the other hand braking must first brake the rear wheels, and then push the piston mechanism to move to the right to brake the front wheels. When (3) ATB brakes, one hand will definitely cause the front wheel to brake first, and then push the piston mechanism to move to the left, causing the rear wheel to brake. Therefore, (4) a device with one-way flow adjustment module is required to make the left and right hands the same It produces a safe brake in which the rear wheels are braked first, and the front wheels are braked rearward.

According to an embodiment of the present invention, the (4) unidirectional flow adjustment module is composed of a cylindrical shape with a hollow cone inside, a hollow round blind hole is connected at the bottom of the rear end, and the bottom of the hollow round blind hole is Adjust the bolt, and there are multiple channels at the bottom to allow the hydraulic oil in the third oil pipeline connected to the bottom of the hollow round blind hole to pass unimpeded. The hollow cone has a built-in cylindrical plug. The diameter of the cylindrical plug is slightly larger than the inner diameter of the hollow round blind hole. There is an inverted hollow blind hole in the cylindrical plug, which allows the adjustment bolt to be inserted and can move up and down without obstruction. Adjust the gap between the cylindrical plug and the hollow cone to maintain an ideal gap and restrict the passage of hydraulic oil to adjust the flow of hydraulic oil flowing through the hollow cone, which can be adjusted according to the needs of the user. The flow of hydraulic oil from the first oil tank to the third oil pipe through the (4) one-way flow adjustment module is restricted, so that the front wheels have a slow braking function. But when the hydraulic pressure is released to return the oil, the hydraulic oil in the brake returns to the first oil tank along the third oil pipe. When flowing through the (4) one-way flow adjustment module, the cylinder plug is pushed up and reaches the hollow cone. The part with a larger diameter at the upper end can pass through without restriction, so the hydraulic oil in the third oil pipeline passes through without obstruction (4) One-way flow adjustment module. In order to prevent the cylindrical plug from being pushed upward by the return oil, the The oil hole is blocked, and there are a plurality of intervals on the top of the cylindrical plug, so that the cylindrical plug and the oil hole are kept at a certain distance without obstructing the passage of hydraulic oil. This (4) one-way flow adjustment module adopts a hollow cone, a cylindrical plug, and an adjustment bolt and a channel at the bottom of a hollow round blind hole in an embodiment of the present invention. This structure is only an example and not as a limitation. The structure (4) one-way flow adjustment module is used as a mechanism to reach the restricted flow. For example, when installed in the oil pipeline of the multifunctional combined braking system of the present invention, the flow through the mechanism can be restricted during braking. When the brake is released, the flow of hydraulic oil flowing back to the oil tank from the brake is not affected and can be adjusted The flow through the (4) one-way flow adjustment module is other types of flow adjustment restriction valves with the same function, such as changing the cylindrical plug to a ball. At the same time, if the rider does not like to use the (4) one-way flow adjustment module, remove the third oil pipe and take out the module. The entire hydraulic brake system will not be affected. Whether (4) The structure of the unidirectional flow adjustment module is an extension of the concept of the present invention, and should fall within the scope of the concept of the present invention.

According to an embodiment of the present invention, a function selection mechanism, the function of this mechanism is that a knob provided on the housing of the multifunctional combined braking system device controls a cylindrical control shaft to select different functions in the piston mechanism The function slot can be changed to (1) one-handed independent brake front and rear wheels (1) SBS, or (2) right hand (or left hand) brakes the front wheels, left hand (or right hand) brakes both front and rear wheels (2) CBS and (3) left and right hands. Simultaneously brake the front and rear wheels (3) ATB) function.

According to an embodiment of the present invention, a function selection mechanism in the multifunctional combined braking system device includes; a control shaft passes through the top of the housing, the wall of the hydraulic cylinder, and the hollow long hole of the piston rod from top to bottom to reach the shaft at the bottom of the housing The function of the seat device is to use a knob on the top of the housing to connect a control shaft to rotate left and right and move up and down to select different functions of the brake; a shaft body is used to drive a latch, and a hollow bolt is used to select different orientations and heights. The bolt seat enables the lower end of the shaft body to be positioned in the functional grooves of different heights and lengths in the piston mechanism, which affects the left and right movement of the piston mechanism Distance, produces a variety of braking functions. In this preferred embodiment, a cylindrical control shaft is selected to control the relationship between the positioning column at the shaft end and the functional groove in the piston mechanism. A bolt can also be selected as the control shaft, and the inner teeth of the hollow bolt are spirally moved up and down to achieve the relationship with the piston. The functional grooves of the mechanism cooperate to produce brakes of different functions. Therefore, if there is a mechanism from the multifunctional combined braking system device shell into the hydraulic cylinder to reach the functional groove of the piston mechanism, rotating the mechanism produces a different fit with the functional groove of the piston mechanism, which affects the left and right movement of the piston mechanism, and the bicycle has different functions. The brakes are all caused by using the concept of the present invention.

According to an embodiment of the present invention, a function selection mechanism passes through the top of the housing top, the wall of the hydraulic cylinder, the hollow long hole of the piston rod and reaches the shaft seat at the bottom of the housing from top to bottom. Torsion and compression spring, the positioning end of the spring element is inserted into the positioning hole at the top of the selector button in the selector button and combined with the spring, the spring positioning end at the other end is pre-twisted and inserted into the spring hole of the housing, and the top of a control shaft is sleeved The spring is locked with the selector button by a screw from the top. The control shaft sleeve is coaxial with the hollow bolt in a hollow bolt. The control shaft and the hollow bolt are combined with a sliding fit, so that the control shaft can move up and down and rotate in the hollow bolt. The external thread of the bolt is locked into the screw hole of the shell for fixing. There is a horizontal perforation on the control shaft, and a latch is tightly fitted in the hole. The inner hole of the center bolt is moved up and down and left and right. At the same time, due to the torsion and compression force of the spring, the control shaft has the potential to rotate in a clockwise direction (with the latch for a 90-degree opening) and stretch the center shaft upward. force. There is a small section at the bottom of the control shaft whose diameter is smaller than the width of the short groove in the piston mechanism is called the positioning column. The positioning column is easily inserted into the (2) CBS groove or (1) SBS groove when the function is selected. It is at the bottom of the positioning column. There is a cylinder with a smaller diameter called a rotating shaft, and the rotating shaft is in sliding fit with the rotating shaft seat of the housing, allowing the rotating shaft to pivot in it to move up and down and rotate left and right.

In the function selection mechanism, the hollow bolt has the function of turning the positioning column to select the braking function. At the bottom of the hollow bolt, according to the upper hexagonal nut of the hollow bolt, it is divided into 0 degrees, 60 degrees, and 120 degrees. It is divided into 3 groups of 6 through-hole latch seats, the latch seat is a 90-degree opening slot, its vertical wall makes the latch close to and blocks the latch due to the torsion spring, and its horizontal wall makes the latch due to the tension of the compression spring Positioning under the horizontal wall, that is, it is stuck at the 90-degree intersection of the vertical wall and the horizontal wall, and at the same time, the lower positioning column of the control shaft is seated in the selected (2) CBS slot or (1) SBS slot. At the bottom of the hollow bolt, the three groups of heights are different into a stepped bolt seat group, starting from 0 degrees is (1) SBS bolt seat, the height of the vertical wall is the same as the functional groove in the piston mechanism, and then go to the second 90 The degree card bolt seat is rotated to the side of the hollow bolt 60 degrees, to (2) CBS card bolt seat, the height of its lifting is the first 0 degree horizontal wall and a short groove depth (for example, 0.3 cm, depending on Depending on the design situation, it is only an example and not limited to this). From the second (2) CBS clamp socket to the third 90-degree opening clamp socket, the hollow bolt rotates 120 degrees to the side to achieve ( 3) The lifting height of the ATB card bolt seat is to increase the depth of a short groove (for example, 0.3 cm, depending on the design situation, only an example and not limited to this), and three hollows can be seen from the above The height difference of the bolt seat of the 90-degree opening on the bolt is a geometrically proportional height increase, and the height changes with the depth of the functional groove.

According to an embodiment of the present invention, when the function selection mechanism is rotated to select the braking function, the work selection button is rotated counterclockwise (depending on the spring torque, the preferred embodiment is clockwise torque), so that the card on the control shaft The bolt is separated from the horizontal wall of the card bolt seat. Due to the extension tension of the compression spring, the card bolt is easily pushed upward and separated from the first (1) SBS card bolt seat to reach the next (2) CBS card bolt seat, for example, the original value is 0. When the degree is high, the latch is located in (1) SBS latch seat, the positioning column on the central axis is synchronously inserted into the (1) SBS elliptical groove in the piston rod, and the selector button is rotated counterclockwise to release the latch (1) ) When the horizontal wall of the SBS card bolt seat is pushed up by the extension tension of the compression spring, it reaches the second (2) CBS at the 60 degree position The latch seat and the positioning post are also lifted from the elliptical groove in the piston rod to the short groove (2) CBS groove, but keep a small gap without contact with the bottom of the groove (2) CBS groove. Similarly, if you continue to reverse the selector button When the hour hand rotates to the position of 120 degrees, the latch rotates 120 degrees synchronously, and sits on the third (3) ATB latch seat of 120 degrees. The positioning column rises beyond the top of the outer diameter of the piston and does not touch the surface of the piston rod. At this time, the bottom end of the shaft at the tail end of the control shaft is still inserted in the shaft seat as a support point of the control shaft. When you want to choose the 60 degree or 0 degree position at the 120 degree position, just press the selector button to make the latch cross the vertical wall of the latch seat, and the latch will automatically turn clockwise to the 60 degree card due to the rebound torque of the torsion spring. The vertical wall of the bolt seat is stuck at the 60 degree bolt seat, and so on, it can be turned to the 0 degree bolt seat. Because the bolt seat has a 90-degree opening, it is easy to move up and down.

According to an embodiment of the present invention, the function description of (1) SBS and (2) CBS on piston displacement related to the positioning column and the function groove on the function selection button; wherein the 0 degree (1) SBS latch on the hollow bolt When the seat is occupied by the latch on the control shaft, the positioning column on the control shaft is located in the (1) SBS groove, which is formed by extending a short section to the right on the center point of the piston rod (about 0.3 cm , For example only, not limited to this), when the long hollow groove is cut to the right along the axis of the piston rod from the middle, the width of the long hollow groove is smaller than that of the elliptical groove (1) SBS groove, so the elliptical groove (1) CBS groove is cut After leaving behind two elliptical arcs, the positioning column sits in the middle of the two elliptical arcs, and the piston mechanism can only move to the left.

According to an embodiment of the present invention; when the function selection button is at 0 degrees, the positioning column occupies (1) the space of the SBS slot. (1) The function of the SBS brake system is to brake only a single front wheel or rear wheel when any hand brake is applied. (1) The SBS groove starts from the axial and longitudinal center of the piston mechanism and extends a distance to the right (facing the piston). Move the force to the left to push the piston mechanism to block the O-ring seat and the second oil pipe leading to the second oil pressure hand by the left check valve. At this time, the oil pressure of the second oil tank rises, (only displacement 0.3 Centimeters are examples, The full braking displacement is about 0.6~0.8 cm, not limited to this.) The limited hydraulic oil is pressed into the fourth oil pipe to make the rear wheel brake at the end of the fourth oil pipe produce light braking. At the same time, the hydraulic oil in the first oil tank has increased the oil pressure at the same time. Under the limited flow of the hydraulic oil through the (4) one-way flow adjustment module, the connected third oil pipe and the front wheel brake brake the front wheels, but due to (4) The flow rate of the unidirectional flow adjustment module is limited, so that the front wheel brake produces a slow increase in the braking force. This kind of front wheel brake slowly increases the pressure, and the rear wheel brakes lightly at the same time. When the hydraulic hand intends to brake the front wheel, it will produce a trilogy of safety braking function in order to avoid sudden braking of the front wheel. This is the standard procedure and function for braking the front wheels. In the future, when front-wheel braking is encountered, in order to save the precious time of your review committee, please refer to [0025] instead of the long description.

An embodiment of the present invention; when the position of the function selector button is at 60 degrees, the latch on the control shaft is seated in the 60-degree hollow bolt (2) CBS latch seat, (2) the CBS groove is a piston mechanism The axial and longitudinal center of the, extend a distance to the right (facing the piston) and the same as (1) SBS groove, forming an elliptical groove, then return to the axial and longitudinal center, and extend to the left to the spacer ring at the left end of the piston. (2) CBS brake has two functions: the first function is to brake the front wheels with one hand alone, and its action and effect are as before [0025] and will not be repeated here. In (2) CBS braking, the second function is; when the second hydraulic pressure hand is pinched with the other hand, the hydraulic oil is immediately pressed into the fourth oil pipe, and enters the rear wheel brake to cause the rear wheel to brake first, and at the same time push the piston mechanism to the right Move to drive the backstop mechanism at the right end to block the passage from the first oil tank to the first oil pipe, increase the oil pressure in the first oil tank, and pass the hydraulic oil through the (4) unidirectional flow adjustment module under the flow restriction. It is sent to the third fuel pipe and the front wheel brake to produce the front wheel brake. This is (2) CBS first brakes the rear wheel and then brakes the front wheel, and the front wheel has a trilogy function of safe braking that slow braking, slowing down and then stopping.

According to an embodiment of the present invention; the 120 degree (3) ATB latch seat on the hollow bolt is occupied by the latch, the positioning column is lifted out of the piston rod, and the bottom of the positioning column is kept at a certain distance from the piston rod At the point where it is not connected, only the shaft at the tail end of the control shaft is placed in the long hollow groove of the piston rod (3) ATB groove, and the tail end of the shaft remains in the shaft seat as a support point for the function selection mechanism. The hollow long groove (3) The width of the ATB groove is larger than the shaft. At this time, the piston mechanism is balanced and clamped at the center point of the hydraulic cylinder due to the compression springs at both ends of the piston mechanism. The piston mechanism can be pushed left or right along the axial direction of the hydraulic cylinder. move. (3) The function of ATB is: when either of the left and right hand brakes, it will have the same function of braking the front wheel or the rear at the same time. When the first hydraulic pressure hand is squeezed down, due to the function of (4) the one-way flow adjustment module, the front wheel brake generated by the front wheels rises slowly. Unlike (1) SBS, the piston moves to the left without restriction , Until the check valve O-ring blocks the channel connected with the O-ring seat at the left end and the second oil pipe. At this time, the hydraulic oil in the second oil tank has risen rapidly, and the hydraulic oil is passed through the fourth oil pipe to the rear wheel. The brake produces rear wheel braking. This kind of braking system that brakes the front and rear wheels with one hand at the same time is called (3) ATB system. When the first oil pressure is pressed down, the first oil tank at the end of the front wheel oil pipe is due to (4) one-way flow adjustment The function of the module is the same as the function described in [0025], which can produce the first brake of the front wheel connected to the first oil tank and the first brake of the rear wheel connected to the second oil tank, which avoids the disadvantage of the front wheel first brake, please review For the original reference, [0025] will not be repeated here, the difference is; the rear wheel has been braked first, and it is no longer a function of assisting the front wheel brake. When the second hydraulic pressure hand is squeezed down, the hydraulic oil in the second oil tank is pressed into the rear wheel brake connected to the fourth oil pipe, causing the rear wheel to brake first, and the piston mechanism is pushed in the direction of the first oil tank, the right end of the piston mechanism The compression spring in the first oil groove becomes shorter after being compressed, forcing the check valve spring at the same end in the check valve spring hole seat to move to the right along the piston axis, pushing the check valve shaft at the other end of the check valve spring Moving forward, the gap between the O-ring on the check valve shaft and the O-ring seat at the front end is very small (for example, about 0.1~0.2 cm, not limited to this), so the O-ring is immediately pushed by the check valve spring The hydraulic oil compressed by the piston in the first oil groove cannot be connected to the first oil pipe through the O-ring seat. The oil pressure in the first oil groove rises, and the connected third oil pipe is in (4) unidirectional flow adjustment mode. Group so that the flow is restricted, the hydraulic oil pressure The front wheel brake produces the front wheel brake. This system that can produce the front wheel and the rear wheel brake at the same time when any one hand brakes is called the "Always two brake" system ((3) ATB). The present invention (3) When either of the left and right hands of ATB brakes, not only the front and rear wheels are braked at the same time, but also the rear wheels are braked first, and the front wheels are braked afterwards, and the front wheel is slowly braked, and the speed is reduced and then braked. It is the essence of the concept of the present invention.

One of the embodiments of the above invention is the multifunctional combined braking system device of the present invention: (1) SBS brakes the front wheels and rear wheels with one hand, (2) CBS brakes the front wheels with the right hand (or left hand) alone, and the other hand can brake the front wheels at the same time And rear wheels, (3) ATB left and right hands can separately brake the front wheels and rear wheels and the front wheels are braked at the same time. (4) One-way flow adjustment module, so that the front wheels can be braked slowly, slowed down and then stopped. . The above-mentioned multi-function brake system is concentrated in a hydraulic cylinder at the same time, and is used for the same piston mechanism and the check mechanism at both ends of the piston. It is controlled by a function selection mechanism that passes through the hydraulic cylinder and the piston mechanism by the shell. Multifunctional combined braking system device.

The multifunctional combined braking system device of the present invention can completely combine three combined braking systems (1) SBS, (2) CBS and (3) ATB plus one function (4) one-way flow adjustment module into one shell , Can be installed in any suitable position of a two-wheeled vehicle, exerting three combined braking systems, adding a front wheel to produce slow braking, slowing down and then stopping the safety braking trilogy is the main conceptual feature of the present invention. If a rider does not like to use (4) one-way flow adjustment module temporarily, you can remove the oil delivery pipe connected to the rear end of (4) one-way flow adjustment module to the front brake, and take out (4) one-way flow adjustment module After reinstalling the fuel pipe, there is no safe braking trilogy function of slow braking, slowing down and braking of the front wheels. The entire combined braking system is not affected, and it is not necessary to take out (4) One-way flow adjustment module and adjust it. The height of the bolts to an unlimited height is one of the advantages of the concept of the present invention.

In order to let your reviewer better understand the essence of the concept of the present invention, a preferred specific embodiment is described as follows: Please refer to FIG. 1, which is a schematic diagram of a multifunctional combined braking system device 1 according to an embodiment of the present invention. This embodiment The multifunctional combined braking system device 1 is applied to two-wheeled vehicles, especially in the bicycle hydraulic disc brake system. For the sake of simplicity, only part of the structure connected with the multifunctional combined braking system device 1 is shown. The concept of the present invention is based on the conventionally known (1) left and right hand brake single-hand brake single wheel (Single-hand brake single wheel, hereinafter referred to as (1) SBS, and in recent years, (2) right hand developed for driving safety (Or left hand) brake the front wheel separately, the left hand (or right hand) brakes the rear wheel and the front wheel at the same time (the European Union is called Combined brake systems, hereinafter referred to as (2) CBS), or (3) when either hand brakes, both hands can brake at the same time Braking the front and rear wheels "Always two brake" (hereinafter referred to as (3) ATB) device, and improving the above three braking systems, all related to one-hand braking of the front wheels, it is easy to happen that the front wheels are faster The key point of the accident that caused a rollover accident when the time was suddenly locked (the inventor once experienced the tragic accident of braking the front wheel at a speed of about 30 kilometers per hour when testing the disc brake system) , And the invented (4) one-way flow adjustment module 49 is installed in the oil hole 491 at the outlet of the first oil tank 43 to limit the flow of hydraulic oil to the front brake, so as to produce a slow brake, slow down and then stop the safe brake The trilogy, the text seems to be very long, but it is less than one in actual braking. The safety brake procedure is automatically completed in seconds. Based on the above, in the M402254 patented mechanical (ATB) braking system that the inventor won the Innovation Gold Medal Award in 101, there is a trilogy of braking functions (ATB ); road test example: When the speed exceeds 4x kilometers, any hand brake can still stop the bicycle safely, and it has passed the most stringent CNS and DIN verification (Test standard: BS EN 14766: 2005 Mountain Bicycle- Safety.). In the present invention, the aforementioned mechanisms (1) to (4) are jointly arranged in a geometric shape housing 21. The geometric shape housing 21 is one of the housing mechanisms 2. The geometric shape housing 21 is suitable for installation due to its small size and light weight. On the bicycle, especially the place where the handlebar 75 of the bicycle and the faucet (not shown) are locked, please refer to Figure 9.

Please refer to Figures 1 and 9 again. When the first hydraulic hand 41 is pinched down to brake, the hydraulic oil passes through the first oil pipe 42 and passes through the O-ring seat 61 of the backstop mechanism 6 to squeeze to the first The oil groove 43 generates the pushing piston mechanism 5, and the hydraulic oil is connected to the (4) one-way flow adjustment module 49 connected to the oil hole 491 connected to the hydraulic cylinder 40, and is connected to the third oil delivery pipe 47 to limit the flow of the hydraulic oil Next, press into the front disc brake 81 (please refer to Figure 9), which is a newly invented bicycle hydraulic brake system device cover. In the non-return mechanism 6 shown in the present invention, the piston mechanism 5 and the function selection mechanism 3 that passes through the housing 21 from the top of the housing 21 and is locked into the housing 21 with a hollow bolt 32, through the piston mechanism 5, insert the tail end into the position The rotating shaft seat 37 at the bottom of the housing 21 constitutes the entire hydraulic braking system of the multifunctional combined braking system device 1 according to an embodiment of the present invention. Each independent mechanism is combined in a housing 21, and at the same time When either hand brakes the front wheel, it will first brake slowly, produce a slowdown, and then stop the safety brake trilogy. In addition, the rear wheel will produce a light brake first, so that the front wheel will slow down first, produce a slowdown, and then brake. The safe braking trilogy of live is more perfect. When the other hand brakes the rear wheels and the front wheels at the same time, it is absolutely a safe braking action that brakes the rear wheels first, and then brakes the front wheels.

Please refer to Figure 1. Please refer to the enlarged view of A and B in the upper right corner of two (4) one-way flow adjustment modules 49. (4) One-way flow adjustment module 49 is installed in the oil tank and oil circuit in a module manner. Please refer to [0018] for detailed explanation. If the rider does not want to use it, the third oil pipe 47 can be removed, and the (4) one-way flow adjustment module 49 can be taken out, which has no effect on the entire oil circuit system. (4) The reason why the unidirectional flow adjustment module 49 is designed between the hydraulic cylinder 40 and the third oil delivery pipe 47 is that there is one less external opening and one less chance of oil leakage. If you want to adjust (4) One-way flow adjustment The flow rate of module 49, as long as the third oil pipe 47 is removed, you can use tools such as a hexagon wrench to turn the adjusting bolt 498 to adjust the gap between the cylindrical plug 494 and the hollow cone 493, and then lock the third oil pipe 47. ,Very convenient. The (4) one-way flow adjustment module 49 is composed of a cylindrical shell 492 with a hollow cone 493 inside. The back end of the hollow cone 493 has a cone blind hole bottom 497, and the cone blind hole bottom 497 has a hollow cone 493. Adjust the bolt 498 and a plurality of channels 499 to facilitate the passage of hydraulic oil in the third oil pipe connected to the bottom 497 of the blind hole of the cone. A hollow cone 493 has a cylindrical plug 494 whose diameter is slightly larger than that of the hollow. The inner diameter of the end of the cone 493, the adjustment bolt 498 on the bottom 497 of the blind hole of the cone, the adjustment bolt 498 can adjust the circle sitting on the top of the adjustment bolt 498 The gap between the plunger 494 and the inner surface of the hollow cone 493 can be adjusted to adjust the flow rate of the hydraulic oil flowing through the hollow cone 493 as required by the user. The hydraulic oil passes through the (4) one-way flow adjustment die from the first oil groove 43 The flow of group 49 to the third oil delivery pipe 47 is restricted, so that the front wheels have a slow braking function. But when the first hydraulic control hand 41 is released to return the oil, the hydraulic oil in the brake returns to the first oil groove 43 along the third oil pipe. When flowing through the one-way flow adjustment module, the cylindrical plug 494 is pushed upwards and reaches the hollow cone. The part with a larger diameter at the upper end of the body 493 can pass through without restriction, so the hydraulic pressure in the third oil pipeline passes through without obstruction (4) One-way flow adjustment module 49; to prevent the cylindrical plug 494 from being pushed upward by the return oil , The oil hole 491 is blocked, and a plurality of intervals 495 are placed between the cylindrical plug 494 and the oil hole 491, so that the round plug 494 and the oil hole 491 are kept at a certain distance, so as not to hinder the passage of hydraulic oil. This (4) one-way flow adjustment module 49 is illustrated in an embodiment of the present invention and is not a limitation. The (4) one-way flow adjustment module 49 using this structure is a module that reaches the restricted flow rate. For example, it is installed in In the front wheel oil pipeline of the multifunctional combined braking system device 1 of the present invention, the flow through the pipeline can be restricted during braking. When the brake is released, the flow of hydraulic oil flowing back to the oil tank from the brake is not affected by other types of restrictions. Valves, such as changing the cylindrical plug to a round ball, all refer to the concept of the present invention, and should all fall within the scope of the present invention.

Please refer to FIG. 2 which is an associated diagram of the structural element combination of the function selection mechanism 3 according to an embodiment of the present invention, which is explained in order from top to bottom; At 30 o'clock, the control shaft 33 will rotate with the selector button 30 without deviation, so that the control shaft 33 can be accurately The upper latch 34 sits in the latch seat set 321 (321 is the general name of the three latches 3211, 3212, and 3213) selected on the hollow bolt 32 to achieve the desired function. There is a spring hole 301 at the top end of the selector button 30. The spring hole 301 allows the spring positioning end 311 at the upper end of the spring 31 to be inserted into the spring hole 301. There is also a spring positioning end 311 at the end of the spring 31. The bottom spring positioning The end 311 is inserted into a spring hole (not shown) of the housing 21 adjacent to the hollow bolt 32. When assembling, after the control shaft 33 passes through the hollow bolt 32 from the bottom of the hollow bolt 32 upwards, the hollow bolt 32 is locked to the housing 21 with the thread at the end, and then the control shaft 33 is pivoted with the spring positioning end 311 at the top of the spring 31 The selector button 30 rotates clockwise (counterclockwise is the same) to make the selector button 30 obtain a certain preset torque. At the same time, the selector button 30 and the spring 31 are pressed downward so that the spring 31 obtains a certain preset compression force at the same time. The selector button 30 and the control shaft 33 are locked and fixed with a screw 38.

Please refer to Figure 2 again, this paragraph continues to describe the function selection mechanism 3, the structure of the latch seat 321 in the hollow bolt; one of the important components of the hollow bolt 32 is a hexagonal nut on the upper half for the wrench to lock In the housing 21, there is an external thread in the lower half. The inner diameter of the hollow bolt 32 is a hollow cylinder, allowing the control shaft 33 to slide in, and can be rotated and moved up and down. A vertical wall is provided at the bottom thread section of the hollow bolt 32 322 and the horizontal wall 324. At the intersection of the two walls, there is an arc-shaped wall 323 that is a quarter of the diameter of the latch 34. The left and right ends of the arc-shaped wall 323 are connected by a vertical wall 322 and a horizontal wall at 90 degrees. 324, compose a set of card bolt seats with a 90-degree opening. Set any plane of the six-leg nut as the starting point of 0 degrees, and the bottom (1) SBS card bolt seat 3211, the height of the horizontal wall 324 is the same as the diameter of the bolt 34 in the control shaft 33, and a round hole penetrating (1) the SBS bolt seat 3211 passes through the front of the bolt seat 3211 and passes through the arc-shaped wall 323 concentrically The diameter of the penetrating hole is slightly larger than that of the bolt 34 that penetrates through the bolt wall at the back of the hollow bolt 32. The second CBS bayonet seat 3212 is seated on the 60-degree central axis of the six-leg nut, and its height is raised to the same height (2) CBS slot 58, which has the same height as the first (1) SBS bayonet The hole of the same diameter of the seat 3211 penetrates the second (2) CBS card bolt seat 3212 to the back bolt wall of the hollow bolt 32, and so on, the third (3) ATB card bolt seat 3213 is seated On the central axis of the 120-degree surface of the hexapod nut, its height is increased by 3 times the height of the bolt 34. There is also a hole with the same diameter as the first (1) SBS bolt seat 3211 through the hole and penetrates the third (3) ATB card bolt seat 3213 to the back bolt wall of the hollow bolt 32. The above three latch seats 3211, 3212 and 3213 from 0 degrees to 120 degrees are combined in a stepped manner to form the latch seat group 321 on the hollow bolt 32.

In the function selection mechanism 3 of one embodiment of the present invention, this paragraph describes the action of operating the selector button 30; when the rotary button 30 is operated, the spring 31 has been preset torsion and pressure when the selector button 30 is installed, causing the card to be locked. The latch seat set 321 and the latch 34 tightly lean against the vertical wall 322 and the horizontal wall 324 of the latch seat set 321 and are connected at both ends of the semicircular wall 323 at 90 degrees to form a latch seat with a right-angle opening slot. Group 321. When the nut is at 0 degrees, turn the selector button 30, and the selector button 30 drives the latch 34 on the control shaft 33 to move the latch 34 away from the horizontal wall 324 in the counterclockwise torque direction (used in this embodiment, not limited to this) After that, the downward pressure of the selector button 30 is reduced, and the latch 34 is pushed upward from the (1) SBS latch seat 3211 due to the preset tension of the spring 31 Enter (2) CBS card socket 3212 on the first floor. The above is the action of lifting the card bolt 34 to the upper layer (2) CBS card bolt seat 3212. The same action can be lifted from (2) CBS card latch seat 3212 to (3) ATB card latch seat 3213. If you want to move the latch 34 from (3) ATB latch seat 3213 to (2) CBS latch seat 3212 on the next layer, simply press the selector button 30 down, and the selector button 30 drives the control shaft 33 The latch 34 moves downward to escape (3) the vertical wall 322 of the ATB latch seat 3213. When the latch 34 downwardly exceeds the vertical wall 322, the latch 34 is bounced back to the next layer due to the preset torsion of the spring 31 (2) The vertical wall 322 of the CBS latch seat 3212, the top end of the latch 34 is at the same time due to the preset tension of the spring 31 so that the top end of the latch rests on the bottom surface of the horizontal wall 324, and the latch 34 is clamped by the torsion and tension of the spring 31 Press in (2) CBS card bolt seat 3212, and so on to move the card bolt down to (1) SBS card bolt seat 3211.

Please refer to FIG. 2 again. In the function selection mechanism 3 of the present invention, the structure and function of the control shaft are described in this paragraph; the upper end structure of the control shaft 33 has been described in [0034], which will not be repeated here. In the middle section of the control shaft 33, there is a latch 34 penetrating the axis of the control shaft. Both ends of the latch 34 protrude from the outer diameter of the control shaft 33, but not larger than the thread bottom diameter of the hollow bolt 32, allowing the latch 34 to follow the control shaft. 33 rotates and moves up and down in the threaded inner hole of the housing 21 locked by the hollow bolt 32 to facilitate the selection of three types of latch seats 321 from 0 degrees, 60 degrees and 120 degrees to latch the latches 34 to produce different braking functions.

Please refer to Figure 2 again. In the function selection mechanism 3 of the present invention, this paragraph describes the positioning column 35 at the end of the control shaft; at the end of the control shaft 33 there is a coaxial short column with a smaller diameter than the control shaft 33 (whichever is smaller is convenient Distinguish between the positioning shaft 35 and the control shaft 33, which can be the control shaft 33) with the same diameter at the time of formal manufacture. This small section of positioning column 35 is when the selector button 30 is rotated, the latch 34 of the control shaft 33 moves up and down, and the latch seat set 321 where the latch 34 is located is opposite to the (2) CBS groove 58 and (1) in the piston rod 53 (3) Three different braking functions of the ATB groove 56 produced by the SBS groove 57 or the detachment of the piston rod 53.

In the function selection mechanism 3 of the present invention, this paragraph describes the shaft 36 at the end of the control shaft 33; the thin shaft at the coaxial end of the control shaft 33 is called the shaft 36, because the shaft 36 is always inserted in the same center in the housing 21 The bottom part is kept at a certain distance from the piston rod 53. In the non-contacting shaft seat 37, the shaft seat 37 and the shaft 36 are slidingly matched to allow the shaft 36 to move up and down and rotate left and right freely.

Please refer to FIG. 3, which is the piston mechanism 5 in one embodiment of the multifunctional combined braking system device of the present invention. In order to achieve the safe braking function of the present invention in all braking actions, the rear wheels are braked first and the front wheels are rear braked. There are three slots in the mechanism to form functional grooves. The three views of the piston mechanism 5 are used to illustrate for the reviewers’ reference; the top picture of this figure is the top view of the piston mechanism 5, which is convenient for explaining the related parts of the assembly. The position and the top view shape and related positions of the three important functional grooves; oil seals 511 and 512 are mechanical oil seals, one on the left and right ends of the piston rod 53, and the left and right ends of the piston rod 53 have an outer diameter that is larger than that of the piston The first spacer ring 521 and the second spacer ring 522 with a large rod 53 and a narrow width. The first spacer ring 521 and the second spacer ring 522 are supported on the back of the first oil seal 511 and the second oil seal 512 and abut against the spacer ring 521 and the vertical plane of the spacer ring 522, the left and right pistons 511 and 512 are sleeved on the oil seal shafts (525, 526) coaxial with the piston rod 53, the oil covers of the left and right pistons 511 and 512 are outwards, and the backs are inward, such as This arrangement is because during braking, the hydraulic oil enters the second oil groove 46 and the first groove 43 from the two pistons 511 and 512 respectively to generate pressure, so the left and right oil seals 511 and 512 are back to back, and the oil seals 511 and 512 face outward resistance. The pressure, in addition to the left and right oil seals 511 and 512, each has a spacer ring 523 and 524 for positioning the oil seals 511 and 512, so that it will not move out of the piston rod 53 due to left and right movement. Each has a diameter at the outermost end of the piston rod 53 The smaller protruding cylinders are called spring seats 551 and 552, which are used to place one end of the compression spring 62 in the backstop mechanism 6 on the outer edges of the spring seats 551 and 552, and are positioned here. The centers of the spring seats 551 and 552 , There is a bottomed round hole called the check valve spring hole seat 54. The check valve spring 66 is tightly inserted into the check valve spring hole seat 54 so that the check valve spring 66 will move left and right with the piston mechanism 5 without detaching. In order to maintain a certain gap between the O-ring 63 and the O-ring seat 61 on the check valve shaft 64 in Figure 5, (the gap is between 0.1 cm and 0.3 cm, only for example, not limited by the number) its importance This is described in the backstop mechanism 6 in FIG. 5.

Please refer to Fig. 3, in the upper right corner of Fig. 3 is the piston mechanism 5. There are three functional grooves with different shapes, lengths and widths in the piston rod 53. The top one is (3) ATB groove 56, with the narrowest width. The length passes through the piston rod 53 from the end of the first spacer ring 521 and reaches the second spacer ring 522. When braking, with the rotating shaft 36 as the center, the piston mechanism 5 is pushed into the first oil groove 43 by the hydraulic oil from the first oil pressing hand 41, and the piston mechanism 5 is pushed to the left, so that the hydraulic oil of the first oil groove is pressed into the connected (4) One-way flow adjustment module 49, when the hydraulic oil is pressed into the front wheels, the flow is restricted, so that the front wheels produce a trilogy of safe braking that slow braking, slowing down and then braking, part of the same time The blocked pressure pushes the piston mechanism 5 to move to the left, so that the O-ring seat 61 in the 2 oil groove 46 at the left end is immediately blocked by the backstop mechanism 6, the pressure in the second oil groove increases, and the hydraulic oil flows through the fourth oil pipe to the rear The brake produces the action of immediately braking the rear wheels. This is the trilogy of safe braking in which the first hydraulic brake of ATB combined braking produces the rear wheels to brake first, so that the front wheels are braked slowly, slowed down and then stopped. Working principle. When the second oil pressing hand 44 is pinched, the pressurized hydraulic oil enters the second oil groove through the second oil delivery pipe 45, the passage 65 and the gap between the O-ring seat 61 and the O-ring 63 on the check valve shaft 64. The fourth oil pipe 48 with lower pressure is immediately pressed into the rear wheel brake, which produces the function of first braking of the rear wheels. At the same time, the rear wheels have been braked and the hydraulic oil pressure rises. The hydraulic oil pushes the piston mechanism 5 to the first oil groove 43 Compression, the piston mechanism 5 drives the check valve spring 66 on the right end of the check mechanism 6 to compress in the direction of the first oil delivery pipe 42 so that the O-ring seat 61 at the end of the first oil delivery pipe 42 is moved by the check valve shaft at the front end of the check valve spring 66 64 and the O-ring 63 sleeved on the check valve shaft 64 are blocked, so that the compressed hydraulic oil in the first oil tank cannot flow from the first oil pipe to the first hydraulic control hand, and can only pass through the first oil tank. (4) One-way flow adjustment module 49 connected to the oil tank 43, when the flow is restricted, it reaches the front wheel brake via the third oil pipe 47, which produces a trilogy of safety braking of slow braking, slowing down and then braking, and then another An important safety brake function; the rear wheel has been braked, the front wheel is braked slowly, and the speed is reduced and then braked. This means that the front wheel is dragging the rear wheel to move in a straight line. It functions like a dog sled. This is (3) the second braking function in the ATB combined braking system. It can be explained from the above; there is a brake in either hand (3) In the ATB combined braking system, whether the first hydraulic hand 41 or the second hydraulic hand 44 actuates, the rear wheels are braked first, and the front wheels are braked rearward, and the front wheels drag the rear wheels to make a slow motion in a straight line. The safe braking trilogy of braking, slowing down and then braking is one of the concepts in the multifunctional combined braking system of the present invention, referred to as (3) ATB braking system.

Please refer to Figure 3, in the upper right corner of Figure 3 is the piston mechanism 5, the second is (2) CBS groove 58, which is wider in width and shorter in length. (2) The starting point of the CBS groove 58 is the axis of the piston rod 53 and the center of the longitudinal line. It extends a short distance to the right (facing the piston rod 53) (for example, about 0.3~0.5 cm is not limited to this). The hydraulic oil is allowed to move the piston from the right. The mechanism is pushed to the left. At the same time, the hydraulic oil of the first oil tank 43 passes through the oil hole 491 connected to the cylinder wall of the hydraulic cylinder 40 (4) One-way flow adjustment module 49. When the hydraulic oil is pressed into the front wheels, the flow is restricted, so that the front wheels A trilogy function of safe braking that produces slow braking, slowing down and then braking. (There is a large number of text descriptions, but it is less than 1 second during actual braking, and the sequence is completed in one go.) At the same time, a part of the blocked pressure pushes the piston mechanism 5 to move to the left (for example, about 0.3~0.5 cm. This is the limit), so that the O-ring seat 61 in the second oil groove 46 at the left end is immediately blocked by the backstop mechanism 6, the pressure in the second oil groove rises, and the hydraulic oil flows to the rear brake through the fourth oil pipe. ) The length of the right end of the CBS groove is limited (for example, about 0.3~0.5 cm is not limited to this), the hydraulic oil is only enough to produce the action of "lightly" braking the rear wheels immediately. This is (2) the first hydraulic control of CBS combined braking When braking, the rear wheel brakes "lightly" first, and the auxiliary front wheels jointly produce slow braking, slow down and then stop the safety braking trilogy, which is more perfect. When the second oil pressing hand 44 is pinched, the pressurized hydraulic oil passes through The second oil pipe 45, the passage 65, the O-ring seat 61 and the O-ring 63 on the check valve shaft 64 enter the second oil groove, and are immediately pressed into the fourth oil pipe 48 with a lower pressure to reach the rear wheel brakes. The rear wheel brakes first. At the same time, the rear wheels are braked. The hydraulic oil pushes the piston mechanism 5 to the first oil groove 43 to compress, the piston mechanism 5 drives the check mechanism 6, and the check valve spring 66 on the right end goes to the first oil delivery pipe. Compression in the direction of 42 to make the passage 65 at the end of the first oil delivery pipe 42 and the O-ring seat 61 blocked by the check valve shaft 64 at the front end of the check valve spring 66 and the O-ring 63 sleeved on the check valve shaft 64, so that The compressed hydraulic oil in the first oil tank cannot flow from the first oil delivery pipe to the first hydraulic control hand, and can only pass through the (4) one-way flow adjustment module 49 connected to the first oil tank 43. The flow rate is restricted. After passing through the third oil pipe 47, it reaches the front wheel brake, producing a trilogy of safe braking of slow braking, slowing down and then braking. At this time, the front wheel is dragging the rear wheel to move in a straight line, which can prevent the occurrence of tail-flicking events. It has the same function as a dog sled. This is (2) the second braking function in the CBS combined braking system. It can be explained from the above; when either of the left and right hand brakes has (2) CBS combined braking system, whether the first hydraulic hand 41 brakes the front wheels alone or the second hydraulic hand 44 actuates the front and rear wheels at the same time, it can The rear wheels are braked first, and the front wheels are braked afterwards. In addition, the front wheels have a trilogy of safe braking, which is slow braking, slowing down and then braking. Both have; the front wheel is dragging the rear wheel to move in a straight line, which can prevent the occurrence of tail-flicking events. The function is like a dog sled.

Please refer to Fig. 3, in the upper right corner of Fig. 3 is the piston mechanism 5, in which the functional slot of the single-handed independent braking system of the front wheel is (1) SBS slot 57, In order to achieve a single-handed independent braking system for the front wheels (1) SBS, (1) SBS slot 57 is specially invented such as the shape of the third slot is oval. The width of this slot is the same as (2) CBS slot, and the position is determined by The axis center of the piston rod 53 and the center of the longitudinal line are the starting point, extending a short distance to the right (for example, about 0.3~0.5 cm, not limited to this), allowing hydraulic oil to push the piston mechanism 5 to the left from the right. This short distance is (1) When the SBS groove 57 brakes, the positioning shaft 38 is the center, and the piston mechanism 5 is pushed into the first oil groove 43 by the hydraulic oil from the first oil pressing hand 41, and the hydraulic oil of the first oil groove is pressed into the connected (4 ) One-way flow adjustment module 49, when the hydraulic oil is pressed into the front wheels, the flow is restricted, so that the front wheels produce a trilogy of safe braking that slow braking, slowing down and then braking. At the same time, a part of the blocked pressure pushes the piston mechanism 5 to move to the left, so that the O-ring seat 61 in the second oil groove 46 at the left end is immediately blocked by the O-ring 63 on the check valve shaft 64 of the check mechanism 6. The pressure in the second oil tank rises, and the hydraulic oil is sent to the rear brake through the fourth oil pipe, so that the rear wheels can only produce an immediate and light braking action of the rear wheels. This is (1) When the first hydraulic hand brake of SBS combined braking, the front wheels are braked separately, and the rear wheels are lightly braked first, and (4) One-way flow adjustment module 49 is used to jointly produce slow braking of the front wheels, slowing down and then braking. The safe braking trilogy of live is more perfect. The precision type single-handed braking of the front wheel of the present invention has the auxiliary braking of the rear wheel, but the action of braking the front wheel alone is still the main. When the rear wheel is braked with the other hand, due to the oval (1) SBS groove, only the piston mechanism 5 is allowed to move a short distance from the center to the left. When the second hydraulic hand is squeezed down, the piston mechanism cannot be displaced to the right. The higher-pressure hydraulic oil from the second hydraulic hand will immediately pass through the fourth oil pipe 48 to the rear wheel brakes. The function of braking the rear wheels individually. The common effect is: any single braking before output can produce light braking for the rear wheels and braking for the front wheels, and the safety braking trilogy of slow braking, slowing down and braking on the front wheels is the concept of the multifunctional combined braking system of the present invention. Third, referred to as (1) SBS brake system.

The purpose of the multifunctional combined braking system device of the present invention is not only to integrate the three types of braking system functions commonly used by the bicycle industry in a single controller, which is convenient to choose according to the place of use and preference, but also to ensure that the braking is carried out in a safe manner. Riders do not need to have the safe braking skills unique to professional cyclists. When braking in an emergency, they only need to pinch the left and right hands to obtain safe braking. Preventing accidents is the highest goal of the concept of the present invention. Due to climate, environmental protection and health and sports factors, the cyclist population is increasing, but 99% are ordinary riders who have not received safe braking training. The concept of the present invention is to invent and create a multi-functional joint for these riders. Braking system device 1. The above-mentioned three kinds of braking systems with different functions from [0041], [0042] to [0043]; (3) ATB, (2) CBS and (1) SBS, the common feature is that they all have the safe braking of the front and rear brakes. Function, plus a rear wheel light brake first, assist the front wheel to produce a slow brake, slow down and then stop the perfect safety brake trilogy. In order to facilitate the reviewer’s understanding, it is shown in a tabular format as follows:

Note: Code description:

(1) SBS: Single-hand brake single wheel (Single-hand brake single wheel, referred to as (1) SBS

(2) CBS: One hand brakes the front wheels individually, and the other hand brakes the rear wheels and the front wheels at the same time (Combined Brake System, referred to as (2) CBS

(3) Any hand brake of ATB brakes the front and rear wheels at the same time. "Always Two Brake" ((3) ATB for short)

It can be clearly seen from the above table. The multifunctional combined braking system device 1 of the present invention is a device that integrates three combined braking systems into one controller. No matter which kind of braking system, the rear wheels will be braked first. The safety brake function of the trilogy of braking, decelerating, and then stopping. This novel safety braking trilogy of slow braking, deceleration, and braking of the front wheels (a large series of text descriptions, but in the actual braking time, it is within 1 second, and the braking quality is improved in one go), which is equivalent to the front wheel drag The rear wheel is braking, It avoids dangerous actions such as rollovers and tail-flicking, just like a dog pulling a sled in the snow in a straight line, there is no danger of tail-flicking, and the braking effect is excellent. In the patent M402254 applied by the inventor, such as (3) ATB brake system, it is mechanically combined with multiple springs according to Hooke’s law to make the rear wheel brake first, the front wheel brakes slowly, and the front wheel drags the rear wheel to brake. The European Union Test standard: BS EN 14766: 2005 Mountain Bicycle-Safety. Strict mountain bike standards, and won the 101st Innovation Gold Medal Award by the Minister of Economy. The same principle is refined from the mechanical brake device to the more complex hydraulic brake system, and multiple brake control systems are combined in one controller, which makes it more convenient to select, higher safety and reliability, and assist It is the main concept of the invention that the rider obtains a safe brake and enjoys the riding pleasure. Furthermore (4) The one-way flow adjustment module 49 is installed in the first oil tank 43 and the first oil pipe 42 in a module manner. If the rider does not want to use it temporarily, the first oil pipe can be removed and the (4) ) One-way flow adjustment module 49 has no effect on the entire oil circuit system. (4) The reason why the one-way flow adjustment module 49 is designed between the hydraulic cylinder 40 and the third oil delivery pipe 47 is that there is one less external opening and one less chance of oil leakage. To adjust (4) the flow control function of the one-way flow adjustment module 49, simply remove the third oil pipe 47, and use tools such as a hexagon wrench to turn the adjustment bolt 496 to adjust the gap between the cylindrical plug 494 and the hollow cone 493 It’s very convenient to adjust the gap and lock the third oil pipe 47. If you do not consider the oil leakage problem, you can connect the flow restriction module with the same function as the one-way flow adjustment module 49 between the third oil pipe 47 and the front wheel brake oil circuit, and the flow restriction function can be adjusted and abandoned at any time.

Please refer to FIG. 5, which is an embodiment of the present invention. In order to achieve various braking functions in the multifunctional combined braking system device 1 of the present invention, the backstop mechanism 6 controls the first hydraulic hand 41 or the second hydraulic pressure The hand 44 leads to the first oil groove 43 or the second oil groove 46 for timely closing or opening function, and the present check mechanism 6 is invented. The description of the check mechanism 6 is as follows; there is a check valve at each end of the piston rod 53 The spring hole seat 54 and the spring seats 551 and 552 are sleeved with a compression spring 62 on the outer edges of the spring seats 551 and 552. A check valve spring 66 is tightly inserted into the check valve spring hole seat 54, and the check valve spring 66 Positioned in it to move left and right with the piston mechanism 5, the other end of the check valve spring 66 is inserted into the short shaft end of a check valve shaft 64, and the spacer ring 67 divides the check valve shaft 64 into a short shaft end at the rear end and a long shaft at the front end. At the end, an O-ring 63 is sleeved on the front end of the check valve shaft 64. The O-ring 63 rests on the vertical surface of the spacer ring 67 and is supported by the spacer ring 67 when compressed by force. At the same time, the spacer ring 67 is also the support when the check valve spring 66 is compressed. The check valve shaft 64 and the O-ring 63 and the O-ring seat 61 arranged on the inner surface of the housing 21 at the left and right ends of the hydraulic cylinder 40 are installed in the After the spring is compressed at the end, the check valve shaft 64 is inserted into the passage 65 through the O-ring seat 61. The diameter of the passage 65 is larger than that of the check valve shaft 64, allowing the front end of the check valve shaft 64 to move back and forth in the passage 65, while making the flow The hydraulic oil flow through the passage 65 is not affected. The backstop mechanism 6 has the same two groups in the present invention, which are respectively installed at the left and right ends of the piston mechanism 5 and abut against the vertical end surfaces of the third spacer ring 523 and the fourth spacer ring 524. After the hydraulic cylinder mechanism 4 is compressed and sealed, the piston mechanism 5 is squeezed on the center points of the first oil groove 43 and the second oil groove 46 in a balanced manner by the left and right compression springs 62. One end of the compression spring 62 is sleeved on the spring seats 551 and 552, and the other One end is pressed tightly on the closed end housing 21 of the first hydraulic cylinder and the second hydraulic cylinder. The two compression springs 62 are compressed to close the O-ring at the front end of the check valve spring 66 to the hydraulic cylinder. A small gap is maintained at the bottom of the O-ring seat 61 on the end (not shown) (for example, the gap is about 0.1~0.2 cm but not limited by this example), the O-ring seat 61 is connected to the passage 65 and the first oil pipeline And the second oil delivery pipe are part of the housing 21. This distance does not prevent the hydraulic oil from flowing freely from the passage 65, but when the brake hydraulic oil of either side brakes, the piston mechanism 5 is pushed, the compression spring 62 and the check valve spring 66 When compressed at the same time, the check valve shaft 64 drives the O-ring 63 sleeved on it forward and presses it tightly on the bottom of the O-ring seat 61, sealing the bottom of the O-ring seat 61 and the connection point of the passage 65, so that It is its function that hydraulic oil cannot pass through the passage 65. When the braking force is cancelled, the piston mechanism 5 is returned to the position before braking by the tension of the compression spring 62, so that the check valve shaft 64 and the O-ring 63 on it follow the return of the piston mechanism 5 to separate from the O-ring seat 61 It is restored to an open shape, allowing the braked hydraulic oil to pass through the channel 65 and return to the respective oil pressure hand oil storage tank.

Please refer to Figures 4A to 4F and Figure 1 is to illustrate the three different braking functions in the multifunctional combined braking system device of the present invention (1) SBS, 2) CBS, (3) ATB group cooperative animation; function selection mechanism 3 and The relative relationship of the action of the piston mechanism 5 in the three braking functions; one embodiment of the present invention: (1) left and right hands individually brake the front or rear wheels (1) SBS; the action of the function selection mechanism 3 and the piston mechanism 5 when the brake function is selected For the relative relationship, the three groups of pictures are collected in the same sheet for the convenience of reviewers to review and compare; the pictures in the upper row are the three brake functions The cross-sectional view of the relative relationship between the button 3 and the piston mechanism 5 can be selected, the lower three groups are relative upper views, and the relative relationship between the positioning column 35 (section) and the rotating shaft 36 in the three braking functions. To facilitate the reviewers’ understanding, only the relevant functional slots are shown separately in thick lines in each figure, as described later; (1) SBS is shown in Figure 4A, when the selector button 30 is at 0 degrees, the latch 34 is positioned on the hollow bolt 32 The first lowest (1) SBS card socket 3211, the positioning lever 35 is inserted in the elliptical groove (1) SBS groove 57, the piston mechanism 5 is allowed to move within the range shown by the thick line, only to the left Moving a short distance, the actuation function is the same as [0043], so I won’t go into details here to save members’ precious time. The specially introduced gap between the cylindrical plug 494 and the hollow cone 493 is set by the adjusting bolt 496 to adjust the flow rate of the original third oil pipeline to be small (assuming it is 60% of the original flow rate, this is only an example, and is not limited by 60%) , This is a gap that can be adjusted at any time. As the rider likes, as long as you remove the third oil pipe, you can adjust the upper and lower gaps of the adjusting bolt 496 with tools such as a hexagon wrench. No more hydraulic oil is restricted to enter the rear brake. This is (1) When the first hydraulic hand brake of SBS combined braking, the front wheels are braked individually, and the rear wheels are braked lightly, then the front wheels are braked slowly, the speed is reduced, and then the safety brake trilogy.

An embodiment of the present invention, please refer to Figures 4B to 4E and Figure 1 is to illustrate the multifunctional combined braking system device 1 of the present invention (2) CBS group cooperation dynamic diagram; one embodiment of the present invention: (2) right hand (Or left hand) brake the front wheel, and the left hand (or right hand) brakes the rear wheel and the front wheel at the same time. Select button When 30 is at 60 degrees, the latch 34 is positioned in the second (2) CBS latch seat 3212 of the hollow bolt 32. The bottom of the (2) CBS slot 58 is on the top of the (1) SBS slot 57, (2) ) The top surface of the CBS groove 58 is at the same height as the outer edge of the piston rod 53, and the positioning lever 35 is inserted into the (2) CBS groove 58, and the piston mechanism 5 can only move to the left for a short distance, and the movement to the right is not restricted. The function is the same as [0042], please refer to the committee members, so I won't repeat it here.

Please refer to Figures 4C to 4F and Figure 1 for an example of the present invention. There are two brake" (3) ATB)) devices: the relative relationship between the function selection mechanism 3 and the piston mechanism 5 when the brake function is selected. When the selection button 30 is at 120 degrees, the stopper 34 is positioned on the second position of the hollow bolt 32. Among the 3 highest (3) ATB bayonet seats 3213, the positioning lever 35 is out of the piston rod 53 and does not contact the piston rod. The piston mechanism 5 can move to the left and right with the direction of the oil pressure, the purpose is to make either the left hand or the left hand brake. At the same time, the rear and front wheels can be braked at the same time. The actuation function is the same as [0041], please refer to the committee members, so I won’t repeat it here.

Please refer to Figure 5, an embodiment of the present invention, in order to more clearly present the concept of the present invention in the multifunctional combined braking system device 1 in the overall operation of the relative relationship between the work piston mechanism 5 and the check mechanism 6, the piston mechanism 5 as In the center, the check mechanism 6 at the left and right ends of the piston rod 53 is composed of the same components, which are respectively installed at both ends of the piston rod 53, taking the right end as an example: the left end of the compression spring 62 (facing FIG. 5) rests against the spacer ring 524 On the right end face, the inner diameter is inserted outside the spring seat 551 A check valve spring 66 with a small outer diameter is not in contact and is sleeved into a compression spring 62 with a larger outer diameter. The suspension does not affect each other's contraction when it is actuated, and the left end is tightly inserted into the check valve spring hole The seat 54 can move left and right with the piston mechanism 5 without disengaging. At the right end is a check valve shaft 64, which is divided into front and rear sections by a spacer ring 67. The rear section is tightly inserted into the inner diameter of the check valve spring 66 to prevent disengagement. , The front section is sleeved with an O-ring. When compressed, the left end surface of the spacer ring 67 is in close contact with the right end of the check valve spring 66. The right end surface of the spacer ring 67 serves as the supporting surface of the O-ring, and the check valve shaft 64 is the sleeve. Enter an O-ring seat 61 and pass through a passage 65 connected to the center hole at the bottom of the O-ring seat 61. The inner diameter of the passage 65 allows the check valve shaft 64 to move back and forth in its inner diameter without affecting the brake. The hydraulic oil circulates, and the channel 65 is pivotally connected to the first oil delivery pipe 42. The first oil delivery pipe is connected to the first hydraulic pressure hand to form a check mechanism 6. The left end of the piston mechanism 5 has another set of check mechanisms 6 which are exactly the same. Go into details.

Please refer to Figures 6A and 6B, an embodiment of the present invention, the relative relationship between the function selection mechanism 3 and the piston mechanism 5 and the backstop mechanism 6 in the overall operation of the multifunctional combined braking system device 1, as shown in Figures 6A and 6B and The changes in Figure 1 are illustrated to facilitate the reviewers’ understanding; (3) ATB brake system is chosen as an example in this paragraph to illustrate all the actions; in the hydraulic cylinder 40, the piston mechanism 5 is the check mechanism 6 at the left and right ends. The compression spring 62 in the middle is balanced and squeezed in the middle of the hydraulic cylinder 40 to divide the hydraulic cylinder 40 into a first oil groove 43 and a second oil groove 46. The shaft 36 (section) in the function selection mechanism 3 passes through the piston rod 53 (this figure is a front sectional view, and only the (section) compression spring 62 of the shaft 36 is sleeved on the piston rod. The outer edges of the spring seats 551 and 512 at both ends of 53 are in close contact with the end surface of the fourth spacer ring 524, and the other end is compressed against the inner surface of the housing 21 of the O-ring seat, and the check valve spring 66 coaxial with the compression spring 62 is placed Inside the compression spring 62, one end is tightly inserted into the bottomed hole groove of the check valve spring seat 54, the other end of the check valve spring 66 is sleeved with a check valve shaft 64, and an O-ring 63 is sleeved on the check valve shaft 64 Above, the O-ring 63 maintains a gap with the O-ring seat 61 at its front end (for example, between 0.1 and 0.2 cm, for reference only, not limited to this), the check valve shaft 64 enters through the O-ring seat 61 Channel 65, the check valve spring 66 is not compressed at this time, the channel 65 allows the check valve shaft 64 to move back and forth with the piston mechanism 5 in the channel 65, and the front end of the channel 65 is connected to the first oil pipe 42 or the second oil pipe 45 , A first hydraulic hand 41 and a second hydraulic hand 44 are connected to the front end of the first oil delivery pipe 42 or the second oil delivery pipe 45, respectively. Please refer to Figure 6A, when the first hydraulic hand is pinched down, hydraulic oil is pressed into the first oil groove 43, pushing the piston mechanism 5 to move to the left, the compression spring 62 at the right end is in the extended state, and the piston mechanism 5 compresses the spring on the left It is compressed, so the length L4 of the compression spring 62 on the left is less than the length L3 of the compression spring on the right. The dead O-ring seat 61 and the passage 65 prevent the hydraulic oil in the second oil groove 46 from passing through the second oil pressing hand 44, and can only be pressed out by the fourth oil pipe 48 to the connected rear wheel, so that the rear wheel will be braked. Function. At the same time, the right O-ring 63 and the bottom of the O-ring seat 61, due to the leftward displacement of the piston mechanism 5, drive the counter valve spring 66 and the check valve shaft 64 and O-ring 63 at the left end to move synchronously to the left. , The gap between the check valve shaft 64 and the O-ring 63 and the O-ring seat 61 is enlarged, but The front end of the check valve shaft 64 is inserted into the O-ring seat 61 and the passage 65. The first oil tank continues to be pressured by the first hydraulic control hand 41, and presses the pressurized hydraulic oil into the (4) one-way flow adjustment module 49, and the restricted flow flows into the front wheel brakes, resulting in slow braking of the front wheels, deceleration and then braking A trilogy of safe braking. In this (3) ATB combined braking system, as long as the first hydraulic hand 41 is pressed down, it will automatically generate a trilogy of safe braking in which the rear wheels are braked first, the front wheels are braked slowly, and the speed is reduced before braking.

Please refer to Figure 6A and Figure 6B and Figure 1 and Figure 9. This paragraph selects (3) ATB brake system as an example. Please refer to Figure 6B. When the second pressing hand 44 is pinched down, the hydraulic oil is pressed into the second oil groove 46, The oil is immediately pressed into the rear brake connected to the fourth oil pipe 48 with a lower pressure, and the function of braking the rear brake immediately occurs. The hydraulic oil in the second oil groove 46 continues to push the piston mechanism 5 to move to the right, the compression spring 62 at the left end is in an extended state, and the compression spring 62 on the right of the piston mechanism 5 is compressed, so the length L2 of the compression spring 62 on the left is greater than that on the right. Compress the spring length L1, and at the same time the right O-ring 63 is pushed by the right-moving piston mechanism 5, so that it is in close contact with the bottom surface of the O-ring seat 61, blocking the O-ring seat 61 and the passage 65, and making the first oil groove 43 The hydraulic oil in the middle can’t flow to the first hydraulic control hand 41, only the third oil pipe 47 can press the pressurized hydraulic oil into (4) the unidirectional flow adjustment module 49, and the restricted flow flows into the front wheel brakes to generate the front wheels. A trilogy of safe braking with slow braking, slowing down and then braking. This is (3) the operating principle of the safe braking trilogy of the second hydraulic brake in the ATB combined braking system that produces absolute first braking when the rear wheel is braked, and the front wheel produces slow braking, slows down and then stops. This is the concept of the present invention. one.
