[0020] In order to make the purpose, technical scheme and advantages of the utility model more clear and obvious, the utility model is further described in detail below by combining with the drawings and examples. It should be understood that the specific examples described here are only used to explain the utility model, and are not used to limit the utility model.

[0021] The brake caliper assembly comprises two groups of clamping pieces 10 and a support connecting the two groups of clamping pieces 10, and a communication groove 11 is formed in each clamping piece 10;

[0022] A piston 20 is movably inserted into the adjacent surfaces of the two groups of clamping pieces 10, one end of the piston 20 is located in the communication groove 11, and a connecting part 21 is arranged at one end of the piston 20 outside the clamping piece 10, heat dissipation ports 22 are formed on both sides of the connecting part 21, and a flow channel 24 is arranged in the piston 20 and connected between the heat dissipation ports 22;

[0023] A brake pad 30 is arranged on the connecting part 21, a heat dissipation channel 31 is arranged in the brake pad 30 and extends in the direction of the brake pad 30, and a heat dissipation hole 32 is arranged in the brake pad 30 and is in communication with the heat dissipation channel 31. The connecting part 21 is located in the heat dissipation hole 32. When the air around the brake pad 30 flows fast, the air enters the heat dissipation channel 31 to perform heat dissipation on the brake pad 30 and the piston 20.

[0024] When braking is needed, the hydraulic system transmits pressure to the piston 20, the piston 20 moves, and the piston 20 drives the brake pad 30 to move towards the brake disc. When the brake pad 30 contacts the brake disc and generates sufficient friction, the rotation speed of the wheel is slowed down, thereby achieving the braking of the vehicle. However, a large amount of heat generated by friction is concentrated on the brake pad 30 and then transmitted to the piston 20. Therefore, during the driving of the vehicle, the air around the brake pad 30 flows fast due to the movement of the vehicle. At this time, the air enters the inside of the brake pad 30 through the heat dissipation channel 31. The heat dissipation channel 31 provides a flow path for the air, so that the air can take away the heat generated by the brake pad 30 during braking. At the same time, after the air enters the heat dissipation channel 31 of the brake pad 30, the air can flow along the flow channel 24 due to the existence of the heat dissipation hole 22 and the flow channel 24, so that the heat inside the piston 20 is taken away by the air entering the inside of the piston 20, and the inside of the piston 20 is cooled in time, thereby effectively reducing the temperature of the piston 20. This heat dissipation mechanism can prevent the piston 20 and the brake pad 30 from being overheated and causing performance degradation during frequent braking, thereby ensuring the normal work and service life of the brake caliper assembly.

[0025] In one embodiment, referring to Figure 1 , a spring is wound between the surface of the piston 20 and the clamp 10. When the braking action ends and the hydraulic pressure disappears, the spring exerts its elastic restoring force to pull the piston 20 back to the original position.

[0026] In one embodiment, referring to Figure 1 and Figure 2 , a plurality of heat conduction columns 33 are fixedly inserted into the brake pad 30 and located on one side of the heat dissipation channel 31. The heat conduction columns 33 increase the heat dissipation area in contact with the air and improve the heat dissipation efficiency of the entire brake pad 30. The heat conduction columns 33 are made of copper.

[0027] In one embodiment, referring to Figure 4 , a groove 23 is arranged at one end of the piston 20 inside the communication groove 11, and a circlip 25 is press-fitted in the groove 23. The circlip 25 can limit the movement distance of the piston, effectively avoiding excessive pressing of the brake pad 30 on the brake disc and the problem of accelerated wear of the brake pad 30.

[0028] In one embodiment, the chamfer of the edge of the groove 23 is 30°, which can avoid damage of the spring 25 and the piston 20 due to excessive extrusion or collision, and facilitate press-fitting of the spring 25.

[0029] In one embodiment, referring to Figure 3 , the surface of the connecting portion 21 is provided with a plurality of sets of recesses along the extension direction thereof, which increases the heat dissipation area of the connecting portion 21 and further improves the heat dissipation effect.

[0030] The above embodiments are only used to illustrate the technical solutions of the present application, rather than limit them.
