Description

Hydraulic brake device

The invention relates to a hydraulic brake device; in particular to an oil pressure brake linkage and time difference device, which uses a check valve with adjustable pressure and flow to make the front and rear wheels of the vehicle above two wheels (including two wheels) A device that produces a linkage and a rear wheel to brake first, and a rear wheel to brake.

The hydraulic brake linkage device of the known technology, especially the brake linkage system of the motorcycle hydraulic pressure disc brake device, is mostly connected by a plurality of types of hydraulic valves, although the ABS (anti-lock brake) function is simultaneously achieved, It also causes manufacturing difficulties, excessive volume, easy oil leakage failure, and relatively high cost of use, such as the related US patents US7549710, US7693295, US8132866 and US8210619, etc., which are only suitable for heavy motorcycles, and Taiwan. Although patents I274698, 200639097 and 200914303 are much smaller than foreign valves, only one or two valves, but the valves used are composed of precision sliding fit valves and oil seals, although the volume is much reduced, but there is relative friction. The moving parts, the maintenance on the use is increased, the service life is reduced, and the manufacturing cost is still high. For the motorcycles under 125CC which are generally preferred by motorcyclists, the hydraulic brakes and the front and rear wheel brake time difference systems (ie, the rear wheels) are installed. First, the car is braked, and the front wheel is braked.) Although the safety of the brakes can be increased, the increased cost is still a disadvantage. At the same time, the brakes and power-off devices on the electric bicycles are almost all on the handlebars of the two bicycles, so that there are more than two cables on the handlebars, which are more chaotic, such as M325972, M416593, and M433363.

In order to improve the safety of motorcyclists, EU countries require ABS and brake linkages to be installed in motorcycles of 125CC or higher in 2016. Motorcycles below 125CC are only required to be equipped with linkage and time difference devices due to cost and price relationship. At present, only motorcycles with more than 200CC in Taiwan are qualified to install expensive ABS devices. The known products and patents are still high-priced products in terms of manufacturing cost and the time difference device. The general motorcycle cannot be installed.

The present invention is directed to improvement in the market as described in the [Prior Art]; the invention is small in size, low in manufacturing technology, and low in cost, and the vehicle is hydraulically braked and the rear wheel is braked first, and the rear wheel is braked, Especially for the device installed on the medium and light two-wheeled vehicles, in view of the above various kinds of the present invention, a ball type check valve with adjustable pressure and flow rate is combined with a gravity ball type check valve to achieve Two-wheeled and two-wheeled disc brakes (only the above is only a preferred embodiment of the present invention, and cannot be used as a limitation to the scope of the present invention) to achieve a simple structure, a small size, and a full-featured function (including Linking, first braking, front and rear braking, rear wheel braking and electric control, etc.), no need for high-precision machine equipment, traditional milling machine can be manufactured, no skilled technicians can do the clamping mold semi-technical production and manufacturing The advantages of assembly, etc., can fully meet the low manufacturing cost, and can be installed in any vehicle type. Except for small and medium-sized motorcycles, any hydraulic disc bicycle can be installed at the same time. A magnetic spring opening device is installed outside the oil pressure linkage device, and a magnetic spring opening device can be installed on the outer casing of the hydraulic brake linkage device when necessary, and an electric control function is generated when the vehicle is braked.

After the first squat, front and rear squat; simply pinch the first hydraulic brake handle in the first hydraulic brake unit (use the first type here to avoid the use of left or right hand in the user) The first hydraulic brake handle can be installed on the left hand side or the right hand side according to the habit, and has no effect on the brake function. The hydraulic brake brake cylinder pushes out the hydraulic oil in the hydraulic cylinder, and the pressurized hydraulic oil passes through the through. The flow regulating oil line directly delivers the hydraulic oil to the rear wheel disc caliper, so that the rear wheel immediately generates the braking effect. When the knight continues to pinch the first hydraulic pressure brake handle, the hydraulic oil in the brake line is The pressure in the hydraulic circuit is increased by the resistance in the rear disc caliper. When the hydraulic oil pressure is higher than the pressure set by the adjustable pressure check valve, the hydraulic oil will adjust the ball of the pressure check valve. Opened by the V-shaped seat, the adjustable pressure check valve becomes a passage, and the pressurized hydraulic oil passing through the passage leads to the front wheel disc brake caliper to generate the brake function of the front wheel, and the program causes the front and rear wheels to be braked. The first wheel brakes, the linkage of the front wheel and the time difference function.

Adjustable flow buffer brake; when the first time the knight pinches the first hydraulic pressure handlebar When the hand is applied, the pressurized hydraulic oil reaches the rear wheel through the through oil passage in the body of the hydraulic brake linkage unit, and a flow adjustment mechanism is arranged in the through oil passage, if the user needs to avoid the brake when the speed is faster. Immediately slamming the rear wheel, the adjustment screw of the flow regulating valve can be adjusted to cause an obstruction to the oil passage, so that the flow rate of the hydraulic oil flowing therethrough is lowered, and the rear wheel brake caliper still generates an immediate brake, but Filling the cylinder in the brake caliper takes a little longer. This extended time is called the buffer time. The purpose is to lower the speed of the vehicle first, and then hold the wheel to get a safer brake.

Gravity check valve; pressurized when the first hydraulic brake handle is pinched at the first time The hydraulic oil also reaches the top of the gravity check valve ball through the oil passage in front of the vertical gravity check valve in the body of the hydraulic brake. Because it is a pressurized hydraulic oil, the pressure will cause the gravity to check the valve. The ball is pressed down more tightly so that the hydraulic oil cannot pass the gravity check valve because the adjustable pressure check valve has not been pushed open at this first time, so the lower end of the gravity check valve is pressureless. State, the gravity check valve will not have oil passing through. When the adjustable pressure check valve is pushed open by the pressure, the oil passages of the entire hydraulic brake linkage unit body are in a uniform pressure state, and all the hydraulic oils are in the same direction. The front and rear wheels are braked, and a micro-stress compression spring can be installed at the top of the gravity check valve to withstand the gravity check valve ball and keep it in the bottom of the V-shaped groove of the check valve. The check valve does not remain vertical and is disengaged from the bottom of the V-shaped seat.

The second hydraulic brake; after pinching the first hydraulic brake handle, if you think of the brake Insufficient force, the second hydraulic brake handle can be pinched, so that the second hydraulic brake brake cylinder pushes the hydraulic oil in the hydraulic cylinder directly to the second disc type hydraulic brake caliper to generate more braking resistance. The second hydraulic brake has different installation methods.

The ball valve tee; combined with the first hydraulic brake caliper in a side-by-side manner with the ball valve tee unit, the top end of the ball valve tee unit has two inlets respectively connected by the first hydraulic brake handle and the second hydraulic brake handle The straight-through oil passages in the body of the hydraulic brake linkage unit are juxtaposed, and three different passages can be produced as needed:

(1) When the straight oil passage in the main body of the first hydraulic pressure brake lever brake unit is first introduced into the hydraulic oil, the magnetic ball in the ball valve tee unit is attracted by the magnetic element and has a slope due to the left and right sides. The concave point generated by the pipeline causes the magnetic ball to stop at the center of the lowest point, and the magnetic ball is pushed to the second oil pressure without pressure by the hydraulic oil pressed by the first hydraulic pressure handle that arrives first. The end of the handle is closed, and the end inlet is blocked, so that the hydraulic oil of the first hydraulic handle is prevented from flowing to the second hydraulic brake handle by the blocked nozzle, resulting in a pressure loss state, the first hydraulic brake handle The hydraulic oil is driven by a magnetic element and a grooved round rod to the rear disc brake caliper to generate a brake function.

(2) Similarly, when the hydraulic pressure of the second hydraulic brake handle is first introduced into the hydraulic oil, the ball in the ball valve tee unit is pushed to the first hydraulic pressure without pressure by the hydraulic oil pressed by the second hydraulic pressure handle. The end of the handle is closed, and the end inlet is blocked, so that the hydraulic oil of the second hydraulic brake handle is prevented from flowing to the first hydraulic brake handle by the nozzle, resulting in a pressure loss state, and the hydraulic oil of the second hydraulic brake handle The brake function is generated by the magnetic element and the grooved round bar leading to the rear disc brake caliper.

(3) When the first and second hydraulic brake handles are left and right, pinch the handlebars at the same time When the pressure of the first and second hydraulic brakes is equal, the magnetic ball does not have too much displacement, and does not block any of the nozzles, allowing the first and second hydraulic handles to be in the pipeline. The hydraulic oil passes at the same time, and the brake calipers of the front and rear wheels generate the brake function.

(4) returning oil; when the first and second hydraulic brake handles of the left and right hands are relaxed, the oil The pressure in the pressure line has been vented, because the return force spring on the handle of the first and second hydraulic brakes is pulled back to the piston of the hydraulic hand brake cylinder to generate a negative pressure and the return spring of the hydraulic cylinder in the brake caliper makes the brake The hydraulic oil in the caliper is reversely applied back to the first and second hydraulic brake oil tanks through the gravity check valve and the straight oil passage to prepare for the next brake.

The three-way third pipe end of the ball valve three-way unit and the hydraulic brake linkage device The straight-through adjustable flow line is connected at the top to become the left-handed two-handed brake linkage. Its function is to use the left-hand brake or the right-hand brake, or both hands to brake the vehicle through the hydraulic two-hand brake linkage unit of the present invention. Brake, the special linkage brake function of the rear wheel brake.

In the hydraulic oil chamber of the hydraulic hand-cranked linkage device, open to the back or front of the body An oil passage is directly connected to the outside, and the oil passage is connected to the piston chamber of the oil piezoelectric control device. When the hydraulic pressure handle is pinched, the pressurized hydraulic oil passes through the passage to the piston chamber of the oil piezoelectric control device. Pushing the magnetic piston component outward, because the back of the magnetic piston component has a compression spring support. When the magnetic piston component is compressed backward, the air in the piston cavity of the magnetic piston component is discharged to the outside of the piston cavity through a waterproof ventilation gasket. Release the brake handle and live on the front of the magnetic piston element The hydraulic oil in the plug cavity returns to the hand sump oil tank, and the magnetic piston component is returned. The clean air is passed through the waterproof ventilating gasket to enter the piston cavity of the magnetic piston component. The cylinder at the front end of the magnetic piston component is used to hold the piston cavity. The partition plate allows a space between the magnetic piston element and the partition to allow the hydraulic oil to enter the piston cavity through the oil pressure passage, and the partition plate prevents the hydraulic oil from entering one side of the electric control device, and the other side of the partition plate is closely attached to a compression spring. The compression spring has a tight end against the top end of the reed switch, and a wire is led to the outside of the reed switch tail end. The wire casing has a hollow bolt, and the bolt is screwed with the inner end screw of the tubular inner casing, and is rotated hollow. The bolt can adjust the distance between the reed switch and the magnetic piston element. When the hydraulic oil enters the piston cavity, the magnetic piston element and the electronic control component (here, the magnetic spring is opened) are separated from the magnetic line of the magnetic piston component, and the magnetic wire is broken. The function of the electric or the circuit is that the oil piezoelectric control device is engaged with the bolt and the hydraulic pressure hand-operated device, if the oil is not used, the piezoelectric control device The vehicle can easily loosen the fixing bolts, remove the oil piezoelectric control device, and plug the oil circuit. The oil piezoelectric control device can be disassembled at any time, and the installation and maintenance are very convenient, so that the traditional brake can be electronically controlled. The device is removed from the handlebars of the left and right handbrakes, so that the number of various function cables (a total of seven) in front of the electric bicycle is reduced by two, which is used on a general bicycle, and can be used as an automatic warning for braking or parking.

Third hydraulic pedal car unit; large motorcycles and four-wheelers are equipped with pedal cars, this Invented in the third brake car pedal device, its function is similar to the first and second hand brake structure, only the handle is changed into a foot pedal, and an oil pressure brake linkage unit is added to the oil circuit control, first Steps to reach the rear wheel first brake, the front wheel rear brake function, install a three-way at the end of the front and rear wheel oil pipes, so that the hydraulic brake oil is separately pressurized for the left and right front wheels and the left and right rear wheels.

Hydraulic two-handed brake linkage; the unit is a combination of a ball valve tee unit and a hydraulic brake linkage unit, which functions in either the left-hand brake or the right-hand brake, or both hands. By means of the brakes of the present invention, it is possible to achieve the special braking function of the rear wheel and the front wheel, and the special braking function of the front wheel and the rear wheel, which is especially suitable for bicycles or two-wheeled electric bicycles.

The third hydraulic pedal car unit: the special function of the hydraulic brake linkage unit of the invention is installed on the pure four-wheeled vehicle, and the conventional pedal car device and the three-way device can easily reach the rear wheel first brake, the front wheel and the rear brake. The function is another preferred embodiment of the present invention.

The hydraulic pressure disc brake device according to the present invention can use the hydraulic brake to connect the vehicle to generate the brake linkage and the rear wheel first brake, and the function of the front wheel and the rear brake, and also change the disc brake disc into a drum hydraulic brake. It will produce the same function, or use the brakes of the drums with the most front discs at present, as long as the rear drum type is changed from the pull type to the hydraulic piston type brake pump.

In order to make it easier for the reviewing committee to understand the structure of the present invention and the efficiencies that can be achieved, the following is a description of the following: First, referring to FIG. 1, the vehicle hydraulic brake linkage device of the present invention is as shown in FIG. Figure 11 shows the body of the hydraulic brake linkage device. The upper oil delivery pipe 14 passes vertically through the adjustable flow adjustment screw 38 and then passes through the lower oil delivery pipe 16 to the rear oil pressure plate caliper of the vehicle, and the hydraulic oil of the upper oil delivery pipe 14 From the first hydraulic hand brake cylinder 13, the lateral direction to the front brake delivery pipe 37 is connected to the adjustable pressure check valve 33, and the ball valve 36 is pressed by the compression spring 35 in the bottom of the V-shaped groove of the adjustable pressure check valve 33. In order to prevent the hydraulic oil from passing freely from the upper oil pipe 14, the adjusting screw 34 is placed at the rear end of the compression spring 35, and the adjustment screw can be used to adjust the stress of the compression spring 35 as needed to achieve the adjustment of the front and rear wheel brake time difference, a gravity inverse The check valve 32 is vertically disposed at the upper end of the compression spring 35, and is connected to the front wheel hydraulic brake through the lower oil delivery pipe 15, and the top end of the gravity check valve 32 is connected to the first circuit oil pipe 31 and the upper oil supply pipe 14.

FIG. 12 in FIG. 1 is a hydraulic oil flow diagram when the hydraulic brake linkage device is just starting to brake, and when the first hydraulic brake handle 11 is pinched, the hydraulic pressure in the first hydraulic hand brake cylinder 13 is pressed. The oil delivery pipe 14 enters the hydraulic brake linkage body 30, and the hydraulic oil first passes through the upper oil delivery pipe 14 into the return oil pipe 31, but the ball that encounters the gravity check valve 32 is stuck down to the check valve due to gravity. The bottom of the V-shaped groove blocks the nozzle, and the other hydraulic oil is successively connected to the front brake delivery pipe 37, but At the beginning of the brakes, the ball valve 36 which is unable to push the adjustable pressure check valve 33 can not pass, and can only pass the lower oil pipe 16 to the second hydraulic plate brake caliper 51 of the second hydraulic brake brake unit 5 In the cylinder, an immediate braking function is generated. If it is desired to slow down the braking speed first, then the adjustment screw 38 can be appropriately adjusted to appropriately limit the hydraulic flow through the lower oil delivery pipe 16.

As shown in Fig. 13 in Fig. 1, the current oil delivery pipe 16 leads to the brake cylinder of the vehicle. After the immediate braking function is generated, the hydraulic pressure of the brake hydraulic oil in the pipeline is filled with hydraulic oil because the rear hydraulic cylinder is filled but the first hydraulic brake brake cylinder 13 is still pressed by the first hydraulic brake handle 11 to force the entire upper oil pipeline 14 The pressure in the lower oil delivery pipe 16 is increased. When the pressure increases beyond the set pressure of the adjustable pressure check valve 33, the ball valve 36 is pushed away from the bottom of the V-shaped groove, so that the adjustable pressure check valve 33 becomes a passage, and the hydraulic oil is compressed. The gap of the spring 35 flows into the lower oil delivery pipe 15 and then flows into the first hydraulic pressure caliper 41 of the first hydraulic brake brake unit 4 to generate a brake function, so that only the first hydraulic brake of the first hydraulic brake unit 1 needs to be pinched. The handle 11 can complete the braking action of the front and rear wheels for the brake linkage function, and also generates the rear wheel (the second hydraulic brake brake unit 5) at the end of the lower oil delivery pipe 16 to drive the vehicle first, and push the vehicle when the pressure is high enough. The adjustable pressure check valve 33 (the first hydraulic brake brake unit 4) causes the front and rear brakes to generate a time difference, and reaches the front and rear of the front and rear wheels, and the time difference between the front and rear brakes. One Pressure within the brake linkage means 3 is advanced system of the invention.

As shown in Figure 1 in Figure 1, when the brake action is completed, the first hydraulic brake is released. The first hydraulic pressure of the unit 1 hits the handle 11 to lose the forward pressure generated by the first hydraulic hand brake cylinder 13 in all the pipelines, and is converted into the first hydraulic pressure brake cylinder 13 to pull back the spring back. The suction force generated by the piston (not shown here) in the first hydraulic hand brake cylinder 13 forms a reverse suction force, and the first hydraulic pressure caliper 41 of the first hydraulic brake brake unit 4 is simultaneously generated in the pipeline. Hydraulic cylinder The internal return force spring pulls back the attractive force generated by the piston in the hydraulic cylinder, and the attraction force is opposite to the pressure when braking, and the two reverse attraction forces combine to make the hydraulic oil in the first hydraulic cylinder clamp 41 hydraulic cylinder After the lower oil pipeline 15 pushes the gravity check valve 32 back through the oil return line 31, flows into the upper oil feed pipe 14, and returns to the first oil pressure brake oil tank 12, and the hydraulic oil in the hydraulic cylinder of the second oil pressure disc caliper 51 In the same way, the pipeline 16 is returned to the first oil pressure brake oil tank 12 via the upper oil pipeline 14 for use in the next brake.

2 is a schematic diagram of a three-way function of a ball valve of the present invention, The 21-way ball valve tee device 61 is formed by the left and right two-way three-way first pipe 67 and the three-way second pipe 62 at an oblique angle to the center of the intersection, so that the intersection center generates a concave ball valve cavity 68. The ball valve cavity 68 is provided with a magnetic ball 63. The magnetic ball 63 is seated on a magnetic element 66. The magnetic element 66 is mounted on a grooved grooved rod 65 surrounded by a groove, and the magnetic ball 63 is recessed. The attraction of the ball valve cavity 68 and the magnetic element 66 is often left in the center of the ball valve cavity 68. The magnetic strength of the magnetic element 66 only causes the magnetic ball 63 to be attracted to the center of the ball valve cavity 68, but when a brake is passed, Pushed away from the center of the ball valve cavity 68, the grooved round bar 65 is placed at the top of the third pass third pipe 64, combined into a three-way device, which functions as a hydraulic oil that allows any direction (lower oil pipe 15 or oil pipe 24) to arrive first. Pushing the magnetic ball 63 in the ball valve cavity 68 toward the opposite nozzle (three-way second line 62 or three-way first line 67) and blocking the other's nozzle (three-way first line 67 or three) Passing the second line 62) to allow the first arrived hydraulic oil (the oil pipe 15 or the oil pipe 24) to pass through the groove round bar 65 to the third pass third line 64

Figure 22 in Figure 2 illustrates the flow of hydraulic oil through the oil pipe 15 into the ball valve. After the three-way first line 67 of the device 6, a hydraulic oil 151 is flushed to the nearest magnetic ball 63, and the magnetic ball 63 is pushed to the third-pass second line 62 (due to the three-way second line 62) There is no pressure inside, so that the nozzle of the third conduit 62 of the three-way is blocked by the magnetic ball 63, and the other hydraulic oil 152 is turned to flow into the three-way third conduit 64 through the grooved round bar 65.

As shown in Fig. 23 in Fig. 2, the same as 22, only the hydraulic oil is introduced through the oil pipeline 24 After the three-way second line 62 of the ball valve tee device 61 is pushed, the magnetic ball 63 is pushed to block the nozzle of the first line 67 (so that there is no pressure in the first line 67 of the three-way line), so that the hydraulic oil 231 is concave. The slot round bar 65 is diverted into the three-way third line 64.

Figure 24 in Figure 2 illustrates the simultaneous input of hydraulic oil to the oil delivery pipe 15 and the oil delivery pipe 24. When the pressure between the three-way first line 67 and the third-way second line 62 is similar, the magnetic ball 63 does not move, so that the hydraulic oil in the oil delivery pipe 15 and the oil delivery pipe 24 flows into the three-way through the groove round bar 65 at the same time. Three lines 64.

Figure 25 in Figure 2 shows that the brake pressure disappears after the brakes are over, and [0025] The oil return pressure as stated in Fig. 14 is the same, and the oil returning hydraulic oil 152 stage 232 flows backward through the third round pipe 64 through the groove round bar 65, and then passes through the three-way first pipe 67 and the three-way second pipe respectively. The path 62 flows back to 15. The first hydraulic brake oil sump 12 is reached and the second oil pressure brake oil sump 22 is reached via the oil delivery pipe 24 for use in the next brake.

As shown in Fig. 3, the combination of the hydraulic brake linkage device 3 and the ball valve tee device 6 becomes A hydraulic hand brake linkage device of a preferred embodiment, FIG. 31 is a piping diagram of the preferred embodiment, and the original structure and performance of the hydraulic brake linkage device 3 and the ball valve tee assembly 6 are unchanged.

As shown in Figure 32 in Figure 3, a new function is shown when any first hydraulic brake handlebar In Figure 32, in Figure 32, the second line of the 62-three-way is blocked, and the hydraulic oil is introduced into the three-way third line 64 through the grooved round rod 65, so that the hydraulic brake linkage device 3 generates the interlocking brake and the front and rear, and before and after. The function of the brakes.

As shown in Fig. 3, when the second hydraulic brake handle 21 is pinched down in Fig. 33, the magnetic ball 63 It is a passage for blocking the first line 67 of the three-way, and the hydraulic oil is turned into the third line 64 through the grooved round rod 65. The same function of the interlocking brake, the rear squat, and the front and rear brakes are also generated.

As shown in FIG. 3, FIG. 34 illustrates the first hydraulic brake handle 11 and the second hydraulic brake. When the handle 21 is simultaneously pinched, the magnetic ball 68 does not move, and the hydraulic oil in the three-way first line 67 and the third-way second line 62 simultaneously turns into the third line 64 through the grooved round rod 65, and also generates The same linkage brakes as before, and the function of the front and rear brakes.

As shown in FIG. 35 in FIG. 3, the oil return condition after the brake is described, and FIG. 1 and FIG. 2 described above. The same, unobstructed hydraulic oil is smoothly connected from the three-pipe first pipeline 67 to the oil pipeline 14 and the third pipeline second pipeline 62 to the oil pipeline 24, so that the brake oil is returned to the first hydraulic brake oil tank 12 and the second oil. The brake oil sump 22 is compressed.

As shown in Fig. 4, in the hydraulic oil chamber 69 of the hydraulic two-hand brake linkage device 8, The oil passage 907 is open to the outside of the body back or the front, and the oil passage 907 is connected to the piston chamber 904 of the oil piezoelectric control device. When the first or second hydraulic pressure grip handles 11, 21 are pinched, the pressure is pressurized. The hydraulic oil passes through the passage 907 to the front end of the piston cavity 904 of the oil piezoelectric control device, and the magnetic piston member 92 is pushed by the hydraulic oil in the piston cavity 904 to move toward the back direction, so that the magnetic piston member 92 and the electronic control component 94 (here, the magnetic spring is opened) the distance is pulled apart, and the electronic control component 94 is disengaged from the magnetic line of the magnetic piston element 92, and the electric control function of the power-off or the circuit is turned on, and the first or second hydraulic pressure is released. When the handles 11 and 21 are used, the brake oil passage will lose pressure, and the hydraulic oil in the front end of the piston chamber 904 is pressed by the compression spring 91, pushing the magnetic piston member 92 to push the hydraulic oil in the piston chamber 904 out of the piston chamber 904, so that the magnetic piston The element 92 is pressed against the partition 905 in the tubular inner casing by the ejector rod 921 so as not to block the oil passage 907 while maintaining the space of the piston cavity 904, so that the hydraulic oil enters the piston cavity 904 through the oil passage 907 when the vehicle is next braked. Inside.

As shown in Figure 4, the hydraulic brake control device 9 is connected with bolts and hydraulic pressure. If the hydraulic device 9 is not used, the fixing bolt can be loosened easily, and the hydraulic brake device 9 is removed from the hydraulic hand brake linkage body 81, and then the oil passage 907 is removed. It can be plugged, the hydraulic brake control device 9 can be disassembled, installed and repaired at any time, which is very convenient and does not affect the basic functions of the hydraulic two-hand brake linkage device. The left and right handcuffs are removed from the handlebars, so that the number of various functions of the electric bicycle handlebars is reduced by two (a total of seven), and the hydraulic bicycles are connected to the bicycles on the ordinary bicycles. And the function of braking after the front wheel and the first wheel, and the automatic warning when driving or parking.

The hollow cavity 906 is centered in the hollow body 906 by a partition 905 as shown in FIG.
