Rotary adjustable brake horseshoe

Abstract

The invention provides a rotary adjustable brake horseshoe. The rotary adjustable brake horseshoe comprises a body, a friction body, a reset telescopic piece, a rotating plate and a retainer; the body comprises a baffle, a first side plate, a second side plate, a front wall plate and a bottom plate; the baffle, the first side plate, the front wall plate and the second side plate are sequentially connected to form a rectangular frame; the length of the bottom plate is smaller than that of the rectangular frame; the bottom plate is horizontally arranged right below the rectangular frame body and is connected with the baffle; a limiting plate which is parallel and opposite to the baffle is arranged on one end, away from the baffle plate, of the bottom plate; the friction body is slidably arranged on the bottom plate and is positioned between the baffle and the limiting plate; a shaft body extending towards the baffle is horizontally arranged on the front wall plate; the rotating plate is rotatably arranged on the shaft body; the retainer is movably arranged on the front wall plate; the rotating plate is provided with at least one positioning hole. According to the rotary adjustable brake horseshoe disclosed by the invention, pulling force to the friction body when the reset telescopic piece performs deformation recovery can be improved by adjusting the position of the rotating plate, so as to ensure that the friction body can be reset smoothly.

Description

technical field [0001] The invention relates to the technical field of vehicle braking, in particular to a rotation-adjustable brake shoe. Background technique [0002] The vehicle brake is an important part of the vehicle and the key to ensuring driving safety. Vehicle brakes commonly used today include drum brakes and disc brakes. Drum brakes are mainly composed of base plates, brake drums, brake shoes, wheel cylinders, return springs and other components. The brake drum is installed on the wheel hub and rotates with the wheel. When braking, the wheel cylinder piston pushes the brake shoe to press the brake drum, and the brake drum is decelerated by friction, forcing the wheel to stop rotating. Drum brake is a relatively traditional brake, which is widely used because of its cheap price and good braking performance. Among them, the brake shoe is a key component of drum brake. In the prior art, the brake shoe is generally composed of a shoe body, a friction body and a re...

Problems solved by technology

[0003] Since the return spring will be deformed and damaged after being used for a period of time, thereby reducing its deformation recovery ability, and the smooth return of the friction body cannot be guaranteed. Therefore, the spring in the brake shoe needs to be replaced every once in a while. The process is complicated and the cost is high. For some , the structure is complex, the brake shoe is not easy to disassemble, and it is more likely to be scrapped because of the return spring
