Traditionally, locomotive hydraulic brake systems are designed to press the rear wheel brake handlebars to brake the rear wheels, and press the front wheel brake handlebars to brake the front wheels. When an emergency occurs, the correct way of operation is to press the rear wheel brake lever first and then press the front wheel brake lever to brake the front wheel. However, in emergency situations, the driver often crashes due to wrong operation.

Common wrong operation: Because the force of pressing the front wheel brake lever is too large, the front wheel is locked and the vehicle is overturned. Because the force of pressing the rear wheel brake lever is too large, it causes the rear wheel to slip, flutter, or even crash. Even if the driver presses the front wheel brake lever and the rear wheel brake lever at the same time, it may be because the braking force of the rear wheel brake device is not enough, which is equivalent to pressing the front wheel brake lever alone, causing the front wheel to lock up and overturn. The position of the front wheel brake lever and the rear wheel brake lever are different in different countries, and the positions on different vehicles are not all the same. For motorcycles in Taiwan, the front brake lever is the right brake lever, and the rear brake lever is the left brake lever.

It should be noted that the drawings are all in a very simplified form and all use inaccurate proportions, which are only used to facilitate and clearly explain the purpose of this creative embodiment.

Please refer to the first diagram and the fifth diagram, wherein the first diagram is a composite interlocking brake driving device provided by the first embodiment of the present invention. And the fifth diagram is a schematic diagram showing the application of the composite interlocking brake driving device of the first diagram to the braking system. As shown in the figure, a braking system 100 includes a composite interlocking brake driving device 1, a first brake triggering device 3, a second brake triggering device 2, a rear wheel braking device 4 and a front wheel braking device 5.

The composite linkage brake driving device 1 includes a cylinder block 11, a piston 12, an abutment element 13, a linkage rod 14, a traction assembly 15, a trigger assembly 16, and an elastic element 17.

The cylinder block 11 has an oil inlet IN11 and an oil outlet OUT11. The piston 12 is movably disposed in the cylinder block 11 and forms an oil pressure space S surrounding the cylinder block 11 and is located at a piston return position with a first stroke distance d1 from the oil inlet IN11. The piston return position indicates the position when the piston 12 has not moved yet, that is, as shown in the first figure. The elastic element 17 is disposed between the cylinder block 11 and the piston 12, more precisely, it is disposed in the oil pressure space S and abuts against the cylinder block 11 and the piston 12, respectively, so that when the piston 12 is not subjected to external force, The piston 12 is returned to the piston return position.

The abutment element 13 is provided corresponding to the piston 12 for operatively abutting and pushing the piston 12 to close the oil inlet IN11 of the piston 12 and squeeze a brake fluid to a brake fluid path P to drive the front wheels Rake device 5. The linkage lever 14 is connected to the abutting element 13.

The traction assembly 15 is connected at one end to the rear wheel braking device 4 and is disposed corresponding to the linkage lever 14 and is located at a first return position from the linkage lever 14 at a second stroke distance d2, as shown in the first figure. The second travel distance d2 may be small, and it may even be regarded that the linkage rod 14 is in contact with the traction assembly 15. The other end of the traction assembly 15 is connected to the first brake trigger The device 3, when triggered by the first brake triggering device 3, can avoid the linkage lever 14 and drive the rear wheel brake device 4.

The trigger assembly 16 is connected to the linkage lever 14 for operatively triggering the linkage lever 14 to move, so that the linkage lever 14 pushes the abutment element 13 and the traction assembly 15 to drive the front wheel brake device 5 and the rear wheel brake device 4.

In this embodiment, the second brake triggering device 2 is a left brake handle, and the first brake triggering device 3 is a right brake handle, but it is not limited thereto. In other embodiments of the present invention, the second brake triggering device 2 may be a right brake handle, and the first brake triggering device 3 may be a left brake handle.

The braking system 100 can be used in motorcycles, electric vehicles, auxiliary electric bicycles, bicycles, and ATVs, and other vehicles having two brake triggering devices and two or more wheels for the driver to perform brake control.

Next, please refer to the first to fifth figures together, wherein the second figure is a schematic diagram showing the traction component of the composite interlocking brake driving device provided by the first embodiment of the present invention to traction the rear wheel brake device; the third figure It is a schematic diagram showing the triggering component of the triggering component of the composite linkage brake driving device provided in the first embodiment of the present invention; the fourth diagram A shows the triggering component of the composite linkage brake driving device provided by the first embodiment of the present invention. Another schematic diagram of the triggering linkage; the fourth diagram B shows another schematic diagram of the triggering mechanism of the triggering component of the composite linkage brake driving device provided in the first embodiment of this creation; the fourth diagram C shows the fourth diagram B A partially enlarged schematic diagram of the area shown in the middle circle A; the fourth D diagram is another schematic diagram showing the triggering linkage trigger lever of the composite linkage brake driving device provided by the first embodiment of this creation; and the fourth E diagram is Shows a partial enlargement of the area shown by circle B in the fourth D image Illustration.

The traction assembly 15 in this embodiment includes a first rope 151, a second rope 152, and a first connecting member 153. The first rope 151 is connected to the first brake triggering device 3, the second rope 152 is connected to the rear wheel brake device 4, and the first coupling member 153 is connected to the first rope 151 and the second rope 152. Moreover, the first connecting member 153 is provided with an opening G for the link rod 14 to pass through. The first connecting member 153 may be a plate-like structure, a column-like structure, a ring-like structure, or other structures that can connect the first rope 151 and the second rope 152 and may have an opening G for the link rod 14 to pass through.

When the first brake triggering device 3 is operatively triggered, the first rope 151 is moved in a first direction D under traction, and the first link 153 is pulled in tandem. In addition, the first connecting member 153 will pull the second rope 152 together to further drive the rear wheel brake device 4. Because the first linking member 153 is provided with an opening G, when the first linking member 153 is pulled, the link rod 14 will not be moved together. When the linkage lever 14 is not moved, the abutment element 13 and the piston 12 will not be moved, and therefore the front wheel brake device 5 will not be driven, as shown in the second figure. In this embodiment, when the driver presses the right brake lever, the rear wheel brake device 4 is driven separately to brake the rear wheel.

The trigger assembly 16 in this embodiment includes a third rope 161 and a second connecting member 162. The third rope 161 is connected to the second brake triggering device 2, and the second connecting member 162 is connected to the third rope 161 and the link lever 14.

When the second brake triggering device 2 is operatively triggered, the third rope 161 is moved in the first direction D by traction, and is triggered together When the linkage lever 14 moves, the linkage lever 14 pushes the abutting element 13. Because there is a second stroke distance d2 between the linkage rod 14 and the second link 162, and there is also a second stroke distance d2 between the abutment element 13 and the piston 12, so within the distance of the second stroke distance d2, the rear wheel Neither the brake device 4 nor the front wheel brake device 5 will act, and it can be regarded as an idle stroke. The second stroke distance d2 can also be used to prevent the braking device from being too sensitive, which is commonly known as excessive braking. If the braking device is too sensitive, it can easily cause the tire to lock up. In addition, the second stroke distance d2 can also prevent a driver with a smaller palm from failing to trigger the brake triggering device.

When the linkage rod 14 moves for the second stroke distance d2, it will contact the first connecting member 153, and the abutment member 13 will contact the piston 12, as shown in the third figure. When the linkage lever 14 continues to move, the first linking member 153 is pushed, so that the first linking member 153 pulls the second rope 152 to drive the rear wheel brake device 4. At the same time, the abutment element 13 also starts to push the piston 12, because the piston 12 and the oil inlet IN11 are separated by a first stroke distance d1, the front wheel brake device 5 has not been driven at this time. When the abutment element 13 pushes the piston 12 to move the first stroke distance d1 and starts to close the oil inlet IN11, the brake oil is first squeezed to the brake oil passage P through the oil outlet OUT11, so that the front wheel brake device 5 can be driven. At this time, the traction assembly 15 also gradually increases the braking force of the rear wheel braking device 4, as shown in the fourth A diagram.

In this embodiment, when the driver presses the left brake lever, he will drive the rear wheel brake device 4 first and then drive the front wheel brake device 5 to achieve the effect of braking two wheels.

If the braking system is configured with a drum brake and a disc brake, generally, the rear wheel brake device 4 is a drum brake, and the front wheel brake device 5 is a disc brake. With the use of drum brakes, the longer the brake pads are used, the more they will wear out, and the braking force will be weakened. The above is just one of the reasons for the weakening of the rear wheel braking power. Regardless of the reason, when the rear wheel braking power is weakened and the front wheel braking power is unchanged, if the driver brakes the front and rear wheels at the same time, the front wheel may also be locked. In the case of a crash.

In view of this, the linkage rod 14 is provided with a buffer hole 141. When the link lever 14 contacts the first link 153, the abutment element 13 contacts the piston 12, and the second brake triggering device 2 continues to be triggered, if the braking force of the rear wheel brake device 4 is insufficient, the link lever 14 The first connecting member 153 is pushed first, so that an end of the linkage rod 14 adjacent to the first connecting member 153 is higher than an end adjacent to the abutting member 13. Due to the buffer hole 141, the linkage rod 14 can move relative to the abutting member 13 when it is inclined, without driving the abutting member 13. The positions of the abutting element 13 and the buffer hole 141 can be compared in the fourth A diagram and the fourth B diagram.

Although the interlocking lever 14 pushes the first linking member 153 at this time, the rear wheel brake device 4 cannot stop the rear wheel at this time because of various reasons that weaken the rear wheel braking force. When the trigger assembly 16 continues to trigger the movement of the linkage lever 14 until the forces at both ends of the linkage lever 14 are equal, so that the linkage lever 14 can simultaneously push the first link 153 and the abutment element 13, braking is started. In addition, the piston 12 and the fuel inlet IN11 are still away from the first stroke distance d1, so when the brake is started, the rear wheel brake device 4 is also driven first. The front wheel brake device 5 is not driven until the piston 12 closes the oil inlet IN11. In addition, the buffer hole 141 may also be provided in the abutting element 13 as long as the linking lever 14 and the abutting element 13 can move relative to each other when the linking lever 14 is inclined.

It should be particularly noted that, please compare the fourth diagram A and the fourth diagram B, because the linkage lever 14 in the fourth diagram B is already tilted, when the driver triggers the second brake triggering device 2 with the same force, the fourth diagram B The braking force provided by the middle front wheel brake device 5 will be smaller than that in the fourth A diagram. Therefore, it can be avoided that the braking force provided by the rear wheel braking device 4 becomes smaller, but the front wheel braking device 5 still provides the braking force of the same strength, resulting in a situation where the front wheels lock up and roll over. In this embodiment, even if the pads of the rear wheel brake device 4 are worn, the relative braking force provided by the rear wheel brake device 4 and the front wheel brake device 5 are the same. In addition, in the case of the fourth diagram B, the maximum braking force provided by the front wheel brake device 5 will also be smaller than the maximum braking force provided by the front wheel brake device 5 in the fourth illustration A.

In the present embodiment, the linkage rod 14 further defines a second buffer hole 142. The trigger assembly 16 is connected to the linkage rod 14 corresponding to the second buffer hole 142. The purpose of the second buffer hole 142 is to change the magnitude of the force arm and the control force, so that when the linkage rod 14 is triggered to move by the trigger component 16, the first link member 153 is pushed first and then the rear wheel brake device 4 is driven first. Then, the linkage lever 14 will push the abutment element 13 and then drive the front wheel brake device 5 in the rear, so as to achieve the effect of driving the rear wheel brake device 4 before driving the front wheel brake device 5. When both the abutting element 13 and the first connecting member 153 are pushed, the second buffer hole 142 will make the end of the linkage rod 14 adjacent to the abutting member 13 higher than the end adjacent to the first connecting member 153. The braking force provided by the front wheel braking device 5 driven by the top element 13 is greater than the braking force provided by the rear wheel braking device 4 driven by the first link 153.

In more detail, the linkage rod 14 is provided with a guide channel 143 communicating with the second buffer hole 142, and the composite linkage brake is driven The device 1 further includes a fixing element 18, a pushing element 19 and a third elastic element 10. The fixing element 18 is an end of the third elastic element 10. In this embodiment, it is a set screw. The pushing element 19 is movably disposed in the second buffer hole 142 and the guide channel 143 corresponding to the trigger component 16, and is a steel ball in this embodiment. The third elastic element 10 is connected to the pushing element 19 and the fixing element 18 and is at least partially disposed in the guide channel 143. Preferably, the third elastic element 10 is completely disposed in the guide channel 143.

When the third elastic element 10 has not been compressed, the pushing component 19 is used to push the trigger component 16 to the side of the second buffer hole 142 near the traction component 15, which is on the left side, as shown in Figures 4B and 4C. As shown. In this embodiment, the pushing element 19 is a pin 1621 for pushing the trigger assembly 16. At this time, the force arm d3 between the trigger assembly 16 and the traction assembly 15 is smaller than the force arm d4 between the trigger assembly 16 and the abutment element 13, so the force pushing the traction assembly 15 will be greater than the force pushing the abutment element 13.

When the forces on the left and right sides are different, the relative position of the latch 1621 and the second buffer hole 142 will change, and the latch 1621 will gradually move to the side of the second buffer hole 142 near the abutting element 13, which is on the right side. The three elastic elements 10 will be compressed, as shown in the fourth D diagram and the fourth E diagram. At this time, the force arm d3 'between the trigger component 16 and the traction component 15 will be larger than the force arm d3, and the force arm d4' between the trigger component 16 and the abutment element 13 will be smaller than the force arm d4, so the abutment element 13 is pushed The force will gradually increase.

When the trigger component 16 is not triggered, the elastic restoring force generated when the third elastic element 10 is compressed starts to push on the pushing element 19, and the latch 1621 is pushed back to the left by the pushing element 19. Therefore, this creation can automatically adjust the arm to balance the force according to different force channels, and The force of pushing the traction assembly 15 and the abutment element 13 should be changed accordingly. It should be noted that the fourth diagram A to the fourth diagram E are only schematic diagrams, which are used to explain the connection and action relationship between various components, and do not mean that the actual objects must be exactly the same as those drawn in the drawings. In addition, there are many reasons for the formation of the fourth B figure. The above description is only one of the possibilities, and the above description should not be used as a limitation. However, after the situations of the fourth diagram B and the fourth diagram C are formed, if the trigger component 16 continues to trigger the linkage rod 14, it is necessary to gradually achieve the situation of the fourth diagram D and the fourth diagram E because the force balance needs to be achieved.

Incidentally, in other embodiments of the present invention, when the second buffer hole is opened on the trigger component 16, the third elastic element 10 and the pushing element 19 may be correspondingly disposed on the trigger component 16 and achieve the above. efficacy.

Next, please refer to the fifth to seventh diagrams, wherein the sixth diagram is a schematic diagram showing the composite interlocking brake driving device provided by the second embodiment of the present invention; and the seventh diagram is a second embodiment of the present invention Schematic diagram of the trigger component of the composite linkage brake driving device provided to trigger the linkage. The main difference between the composite interlocking brake driving device 1a of this embodiment and the composite interlocking brake driving device 1 of the first embodiment lies in the interlocking rod 14a and the trigger assembly 16a, and the rest of the same parts will not be described again. The difference between the linkage lever 14a and the linkage lever 14 is only that the linkage lever 14a does not have a guide channel 143. Therefore, the composite linkage brake driving device 1a does not include a fixing element 18, a pushing element 19, and a third elastic element 10. The buffer hole 141a opened by the linkage lever 14a is substantially the same as the buffer hole 141 in the first embodiment, except that there are differences in the length of the drawing.

In this embodiment, the trigger component 16a includes a second The cylinder 161a, a second piston 162a, and a second elastic element 163a. The second piston 162a is disposed in the second cylinder 161a, and the second elastic element 163a is disposed between the second cylinder 161a and the second piston 162a, and abuts against the second cylinder 161a and the second piston 162a, respectively.

The composite interlocking brake driving device 1a in this embodiment can replace the composite interlocking brake driving device 1 in the fifth figure. When the second brake triggering device 2 is triggered to push the second piston 162a, the second piston 162a triggers the movement of the linkage lever 14a, and the linkage lever 14a pushes the first link 153 and the abutment element 13 to sequentially drive the rear wheels. Brake device 4 and front wheel brake device 5. The situation after the second piston 162a pushes the linkage rod 14a is the same as that in the first embodiment, so it will not be described in detail. Compared with the trigger assembly 16 in the first embodiment, the traction linkage rod 14a moves, the trigger assembly 16a in this embodiment urges the linkage rod 14a to move.

Please refer to the fifth figure, the eighth figure, and the ninth figure together, wherein the eighth figure is a schematic diagram showing the composite interlocking brake driving device provided by the third embodiment of the present invention; and the ninth figure is the eighth figure A perspective view of the first connecting member and the linkage lever in the figure. As shown in the figure, the composite interlocking brake driving device 1b in this embodiment differs from the composite interlocking brake driving device 1 in the first embodiment only in the traction assembly 15b and the interlocking rod 14b, and the rest of the same parts will not be described again.

The traction assembly 15b includes a first connecting member 153b. Different from the first embodiment, the first connecting member 153b does not have an opening G like the first connecting member 153 for the link rod 14 to pass through. The first connecting member 153b includes a first end portion 1531b, a second end portion 1532b, and a first connecting portion 1533b. The first connecting portion 1533b extends along a first end S1. An extending direction D1 extends to a second end S2. The first end portion 1531b is connected to the first end S1 and has at least a first abutting surface A1. The second end portion 1532b is connected to the second end S2.

The link rod 14b has at least one second abutting surface A2 corresponding to the first abutting surface A1, and has a groove Gb corresponding to the first connecting portion 1533b. The groove Gb is used for the first connecting portion 1533b to pass through and reciprocally move in the extending direction D1. In addition, the first connecting portion 1533b and the groove Gb can also reciprocate relative to each other in a horizontal direction D2 Among them, the horizontal direction D2 is a vertical extension direction D1. In addition, the buffer hole 141b opened by the interlocking rod 14b is substantially the same as the buffer hole 141 in the first embodiment, except that the drawing has a difference in length.

Therefore, when the traction assembly 15b is towed, it moves back and forth in the groove Gb without contacting and pushing the link lever 14b, so the rear wheel brake device 4 can be driven separately. When the linkage lever 14b is triggered by the trigger assembly 16, the second abutment surface A2 of the linkage lever 14b will abut the first abutment surface A1, pushing the traction assembly 15b to drive the rear wheel braking device 4. The intention of the traction assembly 15b and the linkage rod 14b to move relative to each other in the horizontal direction D2 is the same as that of the fourth diagram A to the fourth E, so that according to the different forces on the left and right sides, the force arms are changed to push the traction assembly 15b. The force balance with the abutting element 13 is automatically reached.

Finally, please refer to the fifth figure and the tenth figure, wherein the tenth figure is a schematic diagram showing a composite interlocking brake driving device provided by the fourth embodiment of the present invention. As shown in the figure, the composite interlocked brake driving device 1c of this embodiment and the composite interlocked brake drive of the third embodiment The difference of the device 1b is only the linkage rod 14c, and the rest of the same parts will not be described again.

The linkage rod 14c includes a first extension section 141c, a second extension section 142c, and a turning connection section 143c. The first extension section 141c is provided on one side E1 of the cylinder block 11, the second extension section 142c is provided on one end E2 of the cylinder block 11, and the turning connection section 143c connects the first extension section 141c and the second extension section. 142c. Compared with the third embodiment, the combined interlocking brake driving device 1c provided in this embodiment occupies a smaller volume. In addition, the buffer hole 144c opened by the linkage lever 14c is also substantially the same as the buffer hole 141 in the first embodiment.

It should be noted that the first extension section 141c and the second extension section 142c are not necessarily parallel, and the turning connection section 143c does not necessarily need to be perpendicular to the first extension section 141c and the second extension section 142c. As long as the first extension section 141c and the second extension section 142c are located on different sides of the cylinder block 11 and the turning connection section 143c does not collide with the cylinder block 11, the occupied volume can be reduced.

In summary, the brake system provided by this creation and its composite interlocking brake drive device can meet the specifications of the interlocking brake system (CBS). The driver can achieve the purpose of front and rear braking by triggering a single brake triggering device. When this is achieved, the rear wheel brake device is driven first, and then the front wheel brake device is driven. It can also ensure that the braking force provided by the front wheel brake device is greater than that provided by the rear wheel brake device, which can prevent the driver from being nervous in an emergency. The heavy pressure on the brake trigger device caused the front wheels to lock up and roll over.

On the other hand, the buffer hole allows the linkage lever and the abutment element to move relative to each other. When the rear wheel brake device comes, the disc is subject to wear and tear. When the braking force is weakened, this creation can still ensure that the rear wheel braking device is driven first, and the relative braking force between the braking force provided by the front wheel braking device and the braking force provided by the rear wheel braking device is the same. In addition, in this case, the tilting linkage can also reduce the maximum braking force that can be provided by the front wheel braking device, further avoiding the situation where the front wheels lock up and roll over.

With the above detailed description of the preferred embodiments, it is hoped that the characteristics and spirit of the creation can be described more clearly, rather than limiting the scope of the creation with the preferred embodiments disclosed above. On the contrary, the intention is to cover various changes and equitable arrangements within the scope of the patents that this creation intends to apply for.
