Description

Dual-cylinder linked brake distribution device and its system

The present invention relates to a brake distribution device and its system, in particular to a two-cylinder linked brake distribution device and its system.

Traditionally, motorcycle hydraulic brake systems are designed to brake the rear wheel by pressing the rear brake handle, and brake the front wheel by pressing the front brake handle. When an emergency occurs, the correct operation method is to first press the rear brake handle to brake the rear wheel and then press the front wheel brake handle to brake the front wheel. However, in emergency situations, drivers often crash due to incorrect operations.

Common incorrect operation: pressing the front wheel brake handle with too much force causes the front wheel to lock and the vehicle to roll over. Because the force of pressing the rear brake handle is too strong, the rear wheel may slip, spin, or even plow out of control. Even if the driver presses the front brake handle and the rear brake handle at the same time, it may be because the rear brake device does not have enough braking force, which is equivalent to pressing the front brake handle only, causing the front wheel to lock and roll over. The positions of the front brake handle and the rear brake handle vary from country to country, and the positions on different vehicles are not exactly the same. For motorcycles in Taiwan, the front brake handle is the right brake handle, and the rear brake handle is the left brake handle. On 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, the international community gradually requires light motorcycles to be equipped with a linked braking system (CBS) or an anti-lock braking system (ABS). The linked braking system is a braking system that allows the driver to control both front and rear wheels at the same time by simply pressing a single brake handle, reducing the risk of skidding or even rollover caused by single-wheel braking. In other words, the linked braking system can decelerate the front and rear wheels at the same time to maintain vehicle stability and reduce the chance of tire slippage. For example, the European Union has stipulated that new motorcycles must be equipped with an anti-lock braking system (ABS). The use rate of motorcycles in Taiwan is even more widespread. The Ministry of Transportation has stipulated that all new motorcycles in 2019 with a displacement of 126 c.c. or above must be equipped with an anti-lock braking system (ABS), and motorcycles with a displacement of 50-125 c.c. It is necessary to install an anti-lock braking system (ABS) or a coupled braking system (CBS).

In view of the fact that in 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 is likely to cause a skid.

The independent rod 17 is disposed corresponding to the connecting member 16, adjacent to the second cylinder 12, and is operated to move along a moving stroke, and moves relative to the second piston rod body 14 during part of the moving stroke.

In this embodiment, the bottom of the first piston rod body 13 is provided with a first through groove T1 and a first rod hole H1, wherein the first rod hole H1 penetrates the first through groove T1. The bottom of the second piston rod body 14 is provided with a second through groove T2. Preferably, the second rod body hole H2 is connected to the second through groove T2. The linking rod 15 further includes a first pivot portion 151 , a second abutment portion 152 and a trigger connection portion 153 . The trigger connection part 153 has a limiting function structure (similar to an L-shaped groove in the figure) corresponding to the first trigger component 18 to prevent the first trigger component 18 from being separated from the linkage rod 15 . The first pivot part 151 is connected to the trigger connection part 153, is movably disposed in the first through-slot T1, is adjacent to and pivotally connected to the first piston rod body 13, and has a pivot hole corresponding to the first rod body hole H1. H3. The second top portion 152 is connected to the trigger connecting portion 153 , is movably disposed in the second through-slot T2 , and is adjacent to and abutting the second piston rod body 14 .

The connecting member 16 further has a top plane 161 and an arcuate contour portion 162 . The arcuate contour portion 162 is used for the independent rod 17 to push against. In practice, the independent rod 17 will push against the position where the arcuate contour portion 162 is closest to the independent rod 17 to ensure the sensitivity of the push. The abutting plane 161 is far away from the independent rod 17, and is used to abut the arcuate contour portion 162 after the independent rod 17 abuts the arcuate contour portion 162, thereby ensuring that the second piston rod body 14 can be reliably pushed. The independent rod 17 further includes a first top 171 . The first top 171 has an accommodation space S3 corresponding to the second piston rod body 14 . The accommodating space S3 will surround the second piston rod body 14, so that the independent rod 17 can move relative to the second piston rod body 14 during part of the movement stroke.

The first trigger assembly 18 connects the first brake trigger device 3 and the linkage rod 15 to operate the linkage rod 15 so that the linkage rod 15 pushes the first piston rod body 13 and the second piston rod body 14 . The second triggering component 19 connects the second brake triggering device 2 and the independent lever 17 for operatively triggering the independent lever 17 so that the independent lever 17 moves along the movement stroke to push against and push the connecting member 16, thereby causing the connecting member 16 to abut against the connecting member 16. Push up and push the second piston rod body 14. In this embodiment, the first brake trigger device 3 is a left brake handle, and the second brake trigger device 2 is a right brake handle, but it is not limited to this.

In addition, the dual-cylinder linked brake distribution device 1 may also include a third elastic element (not shown) and a fourth elastic element (not shown). The third elastic element is disposed between the linking rod 15 and the first piston rod body 13, so it will be blocked by the first piston rod body 13 and the linking rod 15 from the angle of the drawing. The fourth elastic element is disposed between the connecting piece 16 and the second piston rod body 14. Since the diameter of the second rod hole H2 is smaller, in order to avoid excessively disordered lines, the fourth elastic element is not drawn, but after the above description , a person with ordinary knowledge in the relevant technical field should be able to easily understand the positions and functions of the third elastic element and the fourth elastic element.

Finally, please refer to Figures 3 to 7 together. Figure 5 is a schematic diagram showing the triggering of the independent rod of the dual-cylinder linked brake distribution device provided by the preferred embodiment of the present invention; and Figure 6 is a schematic diagram of A schematic diagram showing that the linkage rod of the dual-cylinder linkage brake distribution device provided by the preferred embodiment of the present invention is triggered.

As shown in the fifth figure, when the second trigger component 19 is triggered by the second brake trigger device 2, the independent rod 17 will be triggered to move. The independent rod 17 will move along the movement stroke to resist the arcuate contour portion 162 of the connecting member 16 and thereby push the connecting member 16 . The moving stroke shown in the figure is a schematic diagram of a moving stroke along a first direction D1. When the connecting member 16 continues to push and then resists and pushes the second piston rod body 14, the second piston rod body 14 will move and close the second oil return port EX2 to squeeze the second brake oil to the second brake oil circuit. , and then drives the second braking device 4 to brake the front wheels. It should be noted that the independent rod 17 may be pressed against the connecting member 16 during the entire movement stroke, or may be pressed against the connecting member 16 during at least part of the movement stroke.

Due to the accommodation space S3, when the independent rod 17 has not yet abutted the connecting member 16 and the connecting member 16 has not yet abutted the second piston rod body 14, the independent rod 17 will move relative to the second piston rod body 14. After the independent rod 17 abuts against the connecting piece 16, the independent rod 17 will move together with the connecting piece 16. When the connecting piece 16 abuts the second piston rod body 14 , the independent rod 17 and the connecting piece 16 will move together with the second piston rod body 14 . And because the connecting member 16 is located above the linking rod 15, and the linking rod 15 is located in the second through groove T2 of the second piston rod body 14, therefore, the connecting member 16 can independently push against and push the second piston rod body 14, without The connecting rod 15 will be pushed, and the first piston rod body 13 will not be further pushed. That is to say, when a user operates the second brake trigger device 2, the second brake device 4 can be driven alone and brake only one wheel. In this embodiment, the front wheel is used as an example, but it is not limited to this. . In other embodiments of the present invention, the second braking device 4 can also brake the rear wheels alone.

When the first triggering component 18 is triggered by the first brake triggering device 3, the linkage rod 15 will be triggered to move. The linkage rod 15 will move along the first direction D1, as shown in the sixth figure. The linking rod 15 will resist and push the first piston rod body 13 and the second piston rod body 14, thereby causing the first piston rod body 13 and the second piston rod body 14 to move respectively and seal the first oil return port EX1 and the second oil return port EX1. The second oil return port EX2 is used to squeeze the first brake oil and the second brake oil into the first brake oil circuit and the second brake oil circuit respectively, thereby respectively driving the first brake device 5 and the second brake device 4, and The front and rear wheels are braked. That is to say, when the user operates the first brake trigger device 3, the first brake device 5 and the second brake device 4 can be driven, and the front wheels and rear wheels can be braked, which complies with the specifications and related regulations of the linked brake system (CBS). regulations.

Compare the position of the connecting member 16 in the second rod hole H2 in the fifth and sixth figures. In the fifth figure, the independent rod 17 will push against the connecting piece 16, and push the second piston rod body 14 through the connecting piece 16 against the second piston rod body 14. Therefore, the connecting member 16 will be located on the side of the second rod hole H2 adjacent to the second cylinder 12 . In the sixth figure, the linking rod 15 directly abuts and pushes the second piston rod body 14 instead of abutting the second piston rod body 14 through the connecting member 16. Therefore, the connecting member 16 will be located in the second rod hole H2. adjacent to the side of the linkage rod 15.

In addition, when the first piston rod body 13 has not yet moved, it is separated from the first oil return port EX1 by a first sealing stroke distance, and when the second piston rod body 14 has not yet moved, it is separated from the second oil return port EX2 by a second sealing stroke distance. The sealing stroke distance can be adjusted to brake the front wheel first or the rear wheel first based on the relationship between the first sealing stroke distance and the second sealing stroke distance. For example, the second sealing stroke distance is smaller than the first sealing stroke distance. When the second piston rod body 14 closes the second oil return port EX2, the first piston rod body 13 has not yet closed the first oil return port EX1, so it will first Brake the front wheels. The rear wheel will be braked only after the first piston rod body 13 continues to move and closes the first oil return port EX1. But the time gap between the two is very small. In addition, the first sealing stroke distance and the second sealing stroke distance can also be combined with the aforementioned first elastic coefficient and second elastic coefficient to further control the braking force in addition to controlling the braking sequence.

Because in the present invention, there is no pivot relationship between the connecting rod 15 and the second piston rod body 14, the connecting member 16 and the independent rod 17. Therefore, when the independent rod 17 alone abuts the connecting member 16 and then alone pushes the second piston rod body 14 to brake the front wheel, it will not drive the linking rod 15 to move, so it is ensured that only the front wheel is braked. Moreover, because of the abutment plane 161 and the arcuate contour portion 162 of the connecting member 16, the sensitivity of the independent rod 17 when abutting can be improved, and the front wheel can be braked reliably. The linkage rod 15 can resist and push the first piston rod body 13 and the second piston rod body 14 to brake the front and rear wheels to comply with the specifications and relevant laws of the linked brake system.

To sum up, the dual-cylinder linked brake distribution device and its system provided by the present invention can use independent rods to independently push against and push the connecting member and then push against and push the second piston rod body, so as to independently drive the second brake device. The linkage rod is used to push the first piston rod body and the second piston rod body to drive the first braking device and the second braking device, thereby complying with the specifications of the linked braking system and related regulations. Because there is no pivotal relationship between the connecting rod and the second piston rod body, the connecting piece and the independent rod, and the independent rod has an accommodation space corresponding to the second piston rod body, therefore, the independent rod can be relative to the second piston rod body When moving, when the connecting member is pushed alone and the second piston rod body is pushed alone to brake the front wheel, it will not drive the linking rod to move, so it can ensure that only the front wheel is braked. In addition, the abutment plane and arc-shaped contour part of the connecting member can improve the sensitivity of the independent rod when it abuts, and can effectively brake the front wheel.
