Embodiment Construction
[0030] The present invention is further described below in conjunction with accompanying drawing:
[0031] Such as Figure 5-11 A brake caliper pin shaft damping structure, comprising a caliper mounting bracket 41, a caliper 1 and a pin shaft 2, the pin shaft mounting portion 42 of the caliper mounting bracket 4 is provided with a bracket hole 41 that is a blind hole, and the bracket The hole 41 is arranged horizontally along the length direction of the pin shaft installation part 42, and one end of the pin shaft 2 extends into the bracket hole 41, and a dust-proof part 3 is arranged on the pin shaft outside the bracket hole, and the dust-proof part 3 It is tubular, and the middle part is a bellows. The dustproof part is set on the pin shaft 2 and the end far away from the bracket hole 41 is in interference fit with the pin shaft 2. The end close to the bracket hole 41 is in elastic contact with the opening of the bracket hole 41 and can Sliding on the pin shaft 2; the connec...

The invention relates to a brake caliper pin damping structure. The structure comprises a caliper mounting support, calipers and pins; support holes which are blind holes are formed in pin mounting parts of the caliper mounting support, and one end parts of the pins extend into the support holes; dustproof pieces are tubular, the middle part of each dustproof piece is a corrugated pipe, the ends,sleeving the pins and away from the support holes, of the dustproof pieces are in interference fit with the pins, and the other ends can slide on the pins; connecting parts of the calipers are fixed on the end parts of the other ends of the pins, and damping sleeves are arranged on the end parts, positioned in the support holes, of the pins; and sealing rings are arranged at one ends of the dustproof pieces, and annular linings are arranged on the inner walls of the sealing rings and make smooth contact with the pins. According to the structure, the two-point support of the dustproof pieces and the damping sleeves enable the pins to linearly move in the support holes, the eccentric wear and drag wear of friction blocks are avoided, and the occurrence rate of noise is reduced; and the structure is simple, and the vibration and noise of the brake calipers are effectively reduced.
Description
technical field [0001] The invention relates to a brake component, in particular to a damping structure of a pin shaft of a brake caliper. Background technique [0002] The role of the brake caliper assembly for automobiles is to provide braking force, so that the driving car can be braked to decelerate or stop according to the driver's manipulation intention; with the increasing popularity of domestic cars, the user group has higher and higher requirements for the performance of the car , Chassis noise and friction block eccentric wear and other related issues are of particular concern. Such as Figure 4 As shown, the existing brake caliper assembly is mainly composed of bolts, calipers, pin shafts, pin shaft dustproof parts, caliper mounting brackets, and friction blocks. After the interference fit between the dustproof part and the pin shaft is integrated, it is then connected to the caliper by bolts, but the dustproof part does not support the pin shaft, nor is it posit...
