Description

Double-cylinder interlocking brake distribution device and its system

The present invention relates to a brake distribution device and a system thereof, in particular to a dual-cylinder linkage brake distribution device and a system thereof.

Traditionally, the hydraulic brake system of motorcycles is designed to press the rear wheel brake handle to brake the rear wheel, and press the front wheel brake handle to brake the front wheel. When an emergency occurs, the correct operation method is to first press the rear wheel brake handle to brake the rear wheel and then press the front wheel brake handle to brake the front wheel. However, in a state of emergency, the driver often causes a crash due to wrong operation.

Common wrong operation: The front wheel locks and the car rolls over because the force of pressing the front wheel brake handle is too large. Because the force of pressing the rear wheel brake handle is too large, the rear wheel slips, the tail flicks, and even the ploughing field is out of control. Even if the driver presses the front wheel brake handle and the rear wheel brake handle at the same time, the braking force of the rear wheel brake device may not be enough, which is equivalent to pressing the front wheel brake handle only, causing the front wheel to lock and roll over. The position of the front wheel brake lever and the rear wheel brake lever is different in different countries, and the positions on different vehicles are not completely the same. For Taiwanese locomotives, the front brake handle is the right brake handle, and the rear brake handle is the left brake handle. For most bicycles in Taiwan, the front brake handle is the left brake handle, and the rear brake handle is the right brake handle.

Therefore, in order to improve braking safety, light locomotives are gradually required to be equipped with a linked braking system (CBS) or an anti-lock braking system (ABS). The linkage braking system is a braking system that allows the driver to control the front and rear wheels at the same time by pressing a single brake handle, reducing the risk of slippage or even rollover caused by single-wheel braking. In other words, the interlocking braking system can decelerate the front and rear wheels at the same time to maintain the stability of the body and reduce the chance of tire slippage. In the European Union, it has been regulated that new locomotives must be mandatory to install anti-lock braking system (ABS). In Taiwan, the utilization rate of locomotives is more popular. The Ministry of Communications has stipulated that locomotives with a displacement of 126c.c. or more in 2019 must be equipped with an anti-lock braking system (ABS), and locomotives of 50-125c.c. Then you need to install an anti-lock braking system (ABS) or a linked braking system (CBS).

In this embodiment, the dual-cylinder linkage brake distribution device 1 further includes a first elastic element 21 , a second elastic element 22 , a third elastic element 23 and a fourth elastic element 24 . The first elastic element 21 is disposed between the first abutting element 15 and the first piston 13 and has a first elastic coefficient.

Please refer to the first figure to the ninth figure together, wherein the second figure is a perspective view showing the first cylinder block and the second cylinder block of the dual-cylinder interlocking brake distribution device provided by the preferred embodiment of the present invention; the third figure It is a perspective view showing the first abutting element, the second abutting element, the interlocking rod and the independent rod of the dual-cylinder interlocking brake distribution device provided by the preferred embodiment of the present invention; the fourth figure shows the preferred embodiment of the present invention. A schematic diagram of the independent lever of the provided dual-cylinder interlocking brake distribution device being triggered; the fifth and sixth figures are schematic diagrams showing that the interlocking rod of the dual-cylinder interlocking brake distribution device provided by the preferred embodiment of the present invention is triggered; and, Figures 7 and 8 are schematic views showing the actuation of the first elastic element and the second elastic element of the dual-cylinder linkage brake distribution device provided by the preferred embodiment of the present invention.

As shown in the second and third figures, the second abutting element 16 defines an abutting groove T1 corresponding to the independent rod 18 . In practice, in order to reduce the volume of the twin-cylinder interlocking brake distribution device 1 , the first cylinder 11 is connected to the second cylinder 12 , and an accommodating groove T2 is formed between the first cylinder 11 and the second cylinder 12 . The second cylinder block 12 includes a main body 121 and a side cover 122 . The main body 121 defines a side accommodating groove T3 corresponding to the second trigger assembly 10 and the independent rod 18 , and the side cover 122 defines a protrusion 181 corresponding to the independent rod 18 . There is a limit accommodating groove T4 for limiting the protruding post 181 . The linkage rod 17 defines a buffer hole H1 corresponding to the second abutting element 16 . In addition, the linkage rod 17 corresponds to the first trigger assembly 19 with a limiting function structure (the drawing is similar to an L-shaped groove), so as to prevent the first trigger assembly 19 from being separated from the linkage rod 17 .

When the second trigger assembly 10 is triggered by the second brake trigger device 2 , the independent rod 18 will be triggered to move. The independent rod 18 moves along the movement stroke to abut and push the second abutment element 16 . The second abutting element 16 compresses the second elastic element 22 and pushes the second piston 14 . The second piston 14 will move and close the second oil return port EX2, so as to squeeze the second brake oil into the second brake oil passage, thereby driving the second brake device 4 and braking the rear wheels. It should be noted that, the independent rod 18 may abut against the second abutting element 16 on the entire moving stroke, or may abut on the second abutting element 16 on at least a part of the moving stroke.

Because the link rod 17 is provided with a buffer hole H1, when the second abutting member 16 pushes the second piston 14, the second abutting member 16 and the link rod 17 will move relative to each other, so the link rod 17 will not be linked and pushed The first abutting element 15 . In addition, it should be noted that when the independent rod 18 moves to the end of a stroke along the movement stroke, the second abutting element 16 still does not move the linkage rod 17 . Therefore, when a user operates the second brake triggering device 2, the second braking device 4 can be driven alone and only the rear wheel can be braked, as shown in the fourth figure.

When the first trigger assembly 19 is triggered by the first brake trigger device 3 , the linkage rod 17 is triggered to move. The linkage rod 17 pushes the first abutting element 15 and the second abutting element 16 respectively. The first abutting element 15 and the second abutting element 16 compress the first elastic element 21 and the second elastic element 22 respectively, and then push the first piston 13 and the second piston 14 respectively. The first piston 13 and the second piston 14 move and close the first oil return port EX1 and the second oil return port EX2 respectively, so as to squeeze the first brake oil and the second brake oil to the first brake oil passage and the second oil return port respectively. The second brake oil circuit further drives the first brake device 5 and the second brake device 4 respectively, and brakes the front wheel and the rear wheel.

It should be noted that the second sealing stroke distance D2 is smaller than the first sealing stroke distance D1, and the second elastic coefficient is smaller than the first elastic coefficient. Therefore, when the linkage rod 17 pushes the first abutting element 15 and the second abutting element 16 , the second piston 14 will first close the second oil return port EX2. As shown in the fifth figure, when the second piston 14 closes the second oil return port EX2, the first piston 13 has not closed the first oil return port EX1, and at this time, the rear wheel will be braked first.

When the linkage rod 17 continues to push the first abutting member 15 and the second abutting member 16, so that the first piston 13 closes the first oil return port EX1, the front wheel will be braked, and the second piston 14 will continue to press Great braking force on the rear wheels. Therefore, when the user operates the first brake trigger device 3, the front wheel and the rear wheel can be braked, so as to achieve the effect of operating a brake trigger device to brake the front and rear wheels, which is in line with the specifications of the linked brake system (CBS) and related regulations. , as shown in Figure 6. It should be noted that no matter how the user operates the first brake triggering device 3 or the second brake triggering device 2, the first lower cup of the first piston 13 (the black dot at the lower end of the first piston 13 in the figure) and the second The second lower cup of the piston 14 (the black dot at the lower end of the second piston 14 in the figure) will not exceed the first oil inlet IN1 and the second oil inlet IN2, so as to avoid the first brake oil and the second brake oil It leaks from the first cylinder block 11 and the second cylinder block 12 to the first abutting element 15 and the second abutting element 16 .

In addition, the connection between the first trigger assembly 19 and the linkage rod 17 is located between the linkage rod 17 and the two pivot ends of the first abutting element 15 and the second abutting element 16 .

In this embodiment, the second elastic coefficient is smaller than the first elastic coefficient. Therefore, when the linkage rod 17 pushes the first abutting element 15 and the second abutting element 16 , the first elastic element 21 and the second elastic element 22 are respectively generated The first recovery force and the second recovery force will also be different.

The first restoring force generated by the first elastic element 21 is greater than the second restoring force generated by the second elastic element 22. Therefore, the interlocking rod 17 will be in the state shown in the seventh figure, and the interlocking rod 17 will be close to the first abutting element One end of 15 is farther from the first cylinder 11 , and one end of the link rod 17 close to the second abutting element 16 is nearer to the second cylinder 12 .

Then, the second restoring force generated by the second elastic element 22 will be greater than the first restoring force generated by the first elastic element 21 . Therefore, the interlocking rod 17 will be in the state shown in the eighth figure, and the interlocking rod 17 will be close to the second restoring force. One end of the abutting element 16 is farther from the second cylinder 12 , and one end of the linkage rod 17 close to the first abutting element 15 is closer to the first cylinder 11 , thereby buffering the braking force of the front and rear wheels.

Therefore, when the second elastic coefficient of the second elastic element 22 is smaller than the first elastic coefficient of the first elastic element 21, not only the second braking device 4 can be driven first, but also the second braking device 4 and the second braking device 4 can be driven first. When both brake devices 5 are driven, the buffer adjusts the braking force of both.

When the user does not operate the first brake triggering device 3 and the second brake triggering device 2, the third elastic element 23 and the fourth elastic element 24 will push the first piston 13 and the second piston 14 respectively, so that the first The piston 13 and the second piston 14 are respectively restored to the first return position and the second return position.

To sum up, the dual-cylinder interlocking brake distribution device and the system thereof provided by the present invention can use the independent rod to push the second abutting element independently, so as to achieve the effect of driving the second braking device independently, and use the interlocking rod to push the first abutting member. The top element and the second abutting element achieve the effect of driving the first braking device and the second braking device, thereby complying with the specification of the linked braking system (CBS) and related regulations. The second elastic coefficient of the second elastic element is smaller than the first elastic coefficient of the first elastic element or the second sealing stroke distance is smaller than the first sealing stroke distance, the second braking device can be driven first and then the first braking device is driven, so as to Avoid the situation where the front wheel locks or the rear wheel slips due to driving the first brake device or the second brake device alone. When the second elastic coefficient is smaller than the first elastic coefficient, the braking force of the second braking device and the first braking device can be adjusted by buffering when both of the second braking device and the first braking device are driven.

In addition, the design of the buffer hole can avoid the structure interference between the linkage rod and one of the first abutting element and the second abutting element when the second triggering component is triggered, so that the single braking device (the first braking device cannot be driven independently) smoothly. or second brake).

On the contrary, the intention is to cover various modifications and equivalent arrangements within the scope of the claimed scope of the present invention.
