Embodiment Construction

[0015] In order to clearly illustrate the technical characteristics of this program, a specific implementation method is used below to describe the program in conjunction with the accompanying drawings.

[0016] to explain.

[0017] A drum brake with automatic and continuously adjustable clearance, which is composed of a fixed plate 1, a right friction plate 2, a return spring group 3, a lower brake cylinder assembly 4, a left friction plate 5, and an upper brake cylinder assembly 6. The plate 1 is fixedly installed on the axle, the upper brake cylinder assembly 6 and the lower brake cylinder assembly 4 are respectively fixedly installed on the fixed plate 1, and the upper buckle of the right friction plate 2 is placed on the upper brake cylinder assembly In the notch of the right brake push cylinder on 6, the lower buckle of the right friction plate 2 is placed in the notch of the right brake push cylinder on the lower brake cylinder assembly 4. In the same principle, the upp...

Abstract

The invention provides a drum type brake with an automatic and continuous adjustable gap. The drum type brake comprises a fixing plate, a right friction sheet, a return spring group, a lower brake cylinder assembly, a left friction sheet and an upper brake cylinder assembly, wherein the fixing plate is fixedly mounted on a vehicle axle; the upper brake cylinder assembly and the lower brake cylinder assembly are fixedly mounted on the fixed plate respectively; an upper buckle part of the right friction sheet is mounted in a right brake push cylinder notch on the upper brake cylinder assembly; and a lower buckle part of the right friction sheet is mounted in a right brake push cylinder notch on the lower brake cylinder assembly. According to the drum type brake with the automatic and continuous adjustable gap, the gap between a brake disc and a brake friction sheet of the drum type brake can be realized, and the gap between the brake disc and the brake friction sheet can be stable; and the brake responding time is shortened and the brake safety is improved.

Description

technical field [0001] The invention relates to the automatic adjustment of the gap between the brake shoe and the brake disc of the vehicle brake, in particular to an automatic and continuously adjustable gap drum brake. Background technique [0002] When braking with drum brakes, the hydraulic pressure pushes the piston in the brake wheel cylinder to move outward, and the wheel cylinder piston then pushes the brake shoe close to the brake wheel, and the brake shoe and brake wheel generate frictional resistance to prevent the rotation of the wheel. The gap between the brake shoe and the brake wheel is called the brake gap. In order to ensure the normal driving of the car, the best brake gap should be maintained between the brake shoe and the brake wheel. The traditional drum brake is used for a period of time. After a period of time, the brake shoe will increase the brake gap between the brake shoe and the brake wheel due to wear, and the increase in the brake gap will affe...
