Background
The braking system is a system that forcibly reduces the movement speed of the sporting goods. On vehicles, braking is usually performed by a brake, which includes a disc brake, also called a disc brake, a drum brake, also called a drum brake, and the like. The floating caliper disc brake is widely applied to automobiles due to the advantages of fast heat dissipation, light weight and the like. The floating caliper disc brake comprises a transmission mechanism, a bracket and a caliper body arranged on the bracket, wherein a sliding pin is arranged on the bracket and penetrates through a sliding pin hole in the caliper body, and the transmission mechanism is connected with a brake block.
A brake disc corresponding to the floating caliper disc brake is mounted on the axle, and the brake pad acts on the brake disc to decelerate the brake disc. The brake disc is fixedly connected with the wheel hub, and the wheel hub is arranged on the axle through two bearings. The whole formed by the brake disc and the hub is called a hub disc assembly. Since the brake disc and the brake pad are braked by frictional wear, when the wear amount of the brake pad and the brake disc reaches a scrapping condition, the brake disc and the brake pad need to be taken out for replacement.
The bracket is sometimes called a bracket, and the existing bracket structure is generally as an automobile disc brake bracket as disclosed in chinese patent literature [ application No.: CN 201510136515.9; publication number: CN 104776134A ]: the support comprises a symmetrical curved beam, support heads are symmetrically arranged at two ends of the curved beam, a round hole is formed in the upper part of each support head, and three bolt holes are formed in the lower part of each support head; the two oppositely arranged bracket heads are connected through the side edge plate, the bracket forms an enclosing structure, and the braking part of the brake disc is positioned between the two curved beams and is enclosed by the bracket. Since the brake portion of the brake disk is surrounded by the bracket and is limited by the bracket structure, the brake disk cannot be removed from the axle and replaced without removing the bracket. Therefore, the existing method for replacing the brake disc is as follows: the brake, i.e. the carrier, is first removed from the vehicle suspension, the hub and the brake disc are then removed from the axle, a new brake disc and hub are re-fitted to the axle, and the brake is then re-positioned and mounted to the suspension. In the process of replacing the brake disc, the brake needs to be repositioned, the installation space of the brake is narrow, the positioning and installation process is often inconvenient, the repositioned brake often deviates from the original position, the brake disc is matched with the brake disc after repositioning, the braking effect is affected due to the change, the positioning process often needs to be debugged repeatedly, and therefore the hub disc assembly or the brake disc is inconvenient to replace.
