Description

Double-cylinder linkage brake distribution device

This creation is about a brake distribution device, especially a dual-cylinder linkage brake distribution device.

Traditionally, the locomotive hydraulic brake system is designed to brake the rear wheels by pressing the rear brake handle, and pressing the front brake handle to brake the front wheels. 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 an emergency, drivers often crash due to wrong operations.

Common mistakes: The front wheel locks up and the car rolls over because of the excessive force pressing the front wheel brake handle. Because the force of pressing the rear wheel brake handle is too large, the rear wheel slips, flicks, and even plows out of control. Even if the driver presses the front wheel brake lever and the rear wheel brake lever at the same time, the braking force of the rear wheel brake device may be insufficient, which is equivalent to pressing the front wheel brake lever only, causing the front wheels to lock up and overturn. The positions 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 completely the same. For Taiwanese motorcycles, the front brake lever is the right brake lever, and the rear brake lever is the left brake lever. In most bicycles in Taiwan, the front brake lever is the left brake lever, and the rear brake lever is the right brake lever.

Therefore, in order to improve braking safety, light-duty locomotives are gradually required to be equipped with a linked braking system (CBS) or an anti-lock braking system (ABS). The interlocking brake system is a brake system that allows the driver to control the front and rear wheels at the same time by pressing a single brake lever, reducing the risk of slipping or even rollover caused by single-wheel braking. In other words, the interlocking brake system can decelerate the front and rear wheels at the same time, maintain the stability of the body, and reduce the chance of tire slipping. For the European Union, it is mandatory to install an anti-lock braking system (ABS) on newly manufactured locomotives. Taiwan’s locomotive usage rate is more popular. The Ministry of Transport has stipulated that in 2019, new locomotives with a displacement of 126c.c. or more must be mandatory to install anti-lock braking systems (ABS), 50-125c.c. It is necessary to compulsorily install an anti-lock braking system (ABS) or a linked braking system (CBS).

In view of the prior art, braking the front wheel alone is likely to cause the front wheel to lock and roll over, or braking the rear wheel alone may easily cause slippage.

Please refer to the first to the ninth figures together. The second figure is a perspective view of the first cylinder and the second cylinder of the dual-cylinder interlocking brake distribution device provided by the preferred embodiment of this creation; the third figure It is a three-dimensional view showing the first abutting element, the second abutting element, the linkage rod and the independent rod of the dual-cylinder linkage brake distribution device provided by the preferred embodiment of this creation; The provided schematic diagram of the independent lever of the dual-cylinder linkage brake distribution device being triggered; the fifth and sixth diagrams are schematic diagrams showing the triggering of the linkage lever of the dual-cylinder linkage brake distribution device provided by the preferred embodiment of this creation; and, The seventh and eighth figures are schematic diagrams showing the action 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 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 dual-cylinder interlocking brake distribution device 1, the first cylinder block 11 is connected to the second cylinder block 12, and a containing groove T2 is formed between the first cylinder block 11 and the second cylinder block 12. The second cylinder 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 corresponds to a convex post 181 of the independent rod 18. There is a limiting accommodating slot T4, and the limiting accommodating slot T4 is used for limiting the protrusion 181. The linkage rod 17 defines a buffer hole H1 corresponding to the second abutting element 16. In addition, the linkage rod 17 will correspond to the first trigger assembly 19 to provide a structure with a limit function (the drawing is similar to an L-shaped groove) to prevent the first trigger assembly 19 from being separated from the linkage rod 17.

When the second triggering component 10 is triggered by the second brake triggering device 2, it will trigger the independent rod 18 to move. The independent rod 18 moves along the moving stroke to resist and push the second abutting element 16. The second abutting element 16 will compress the second elastic element 22 to push the second piston 14. The second piston 14 will move and close the second oil return port EX2 to squeeze the second brake fluid to the second brake fluid path, thereby driving the second brake device 4 and braking the rear wheels. It should be noted that the independent rod 18 can be pushed to the second abutting element 16 in all the movement strokes, or can be pushed to the second abutting element 16 in at least part of the movement stroke.

Because the linkage rod 17 is provided with a buffer hole H1, when the second abutting element 16 pushes the second piston 14, the second abutting element 16 will move relative to the linkage rod 17, so the linkage rod 17 will not be linked and pushed First abutment element 15. In addition, it should be noted that when the independent rod 18 moves along the movement stroke to an end of the stroke, the second abutting element 16 still does not cause the linkage rod 17 to move. Therefore, when a user operates the second brake triggering device 2, he can drive the second brake device 4 alone and brake only the rear wheels, as shown in the fourth figure.

When the first triggering component 19 is triggered by the first brake triggering device 3, the linkage rod 17 is triggered to move. The linkage rod 17 will push 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 will move separately and close the first oil return port EX1 and the second oil return port EX2 to respectively squeeze the first brake fluid and the second brake fluid to the first brake fluid path and The second brake oil circuit drives the first brake device 5 and the second brake device 4 respectively, and brakes the front wheels and the rear wheels.

It should be noted that the second sealing stroke distance D2 is less than the first sealing stroke distance D1, and the second elastic coefficient is less 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. At this time, the rear wheel will be braked first.

When the linkage rod 17 continues to push the first abutment element 15 and the second abutment element 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 increase 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 to achieve the effect of operating a brake trigger device to brake the front and rear wheels, which complies with the specifications and related regulations of the linked braking system (CBS) , As shown in the sixth figure. It should be noted that no matter how the user operates the first brake trigger device 3 or the second brake trigger device 2, the first lower cup of the first piston 13 (the black spot 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 spot 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 fluid and the second brake fluid It leaks from the first cylinder 11 and the second cylinder 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 abutment element 15 and the second abutment 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 respectively generate The first restoring force and the second restoring force will be different.

The first restoring force generated by the first elastic element 21 will be greater than the second restoring force generated by the second elastic element 22. Therefore, the linkage rod 17 will assume the state shown in the seventh figure, and the linkage rod 17 will be close to the first abutting element. One end of 15 will be farther from the first cylinder 11, and the end of the linkage rod 17 close to the second abutting element 16 will be closer 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 linkage rod 17 will assume the state shown in the eighth figure, and the linkage rod 17 will approach the second One end of the abutting element 16 will be far away from the second cylinder 12, and an end of the linkage rod 17 close to the first abutting element 15 will be closer to the first cylinder 11, thereby achieving the effect of buffering the braking force of the front and rear wheels.

Therefore, in the case where 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 can the second brake device 4 be driven first, but also the second brake device 4 and the When both of the braking devices 5 are driven, the braking force of both is buffered and adjusted.

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 return to the first return position and the second return position, respectively.

In summary, the dual-cylinder linkage brake distribution device and its system provided by this creation can use independent rods to independently push the second abutting element to achieve the effect of independently driving the second brake device, and use the linkage rod to push the first abutment The top element and the second abutment element achieve the effect of driving the first brake device and the second brake device, thereby complying with the specifications and related regulations of the linked braking system (CBS). The second elasticity coefficient of the second elastic element is smaller than the first elasticity coefficient of the first elastic element or the second sealing stroke distance is shorter than the first sealing stroke distance, the second brake device can be driven before the first brake device is driven, thereby Avoid driving the first brake device or the second brake device alone to cause the front wheels to lock up or cause the rear wheels to slip. The second elastic coefficient is smaller than the first elastic coefficient. When both the second brake device and the first brake device are driven, the braking force of both can be buffered and adjusted.

In addition, the design of the buffer hole can prevent the linkage rod from causing structural interference with one of the first abutting element and the second abutting element when the second triggering assembly is triggered, and the single brake device (first brake device) cannot be smoothly driven independently. Or the second brake device).

On the contrary, its purpose is to cover various changes and equivalent arrangements within the scope of the patent application for this creation.
