A single shoe pin brake

Abstract

The invention discloses a single-shoe pin brake, which comprises a mounting plate. A mounting hole is opened inside the mounting plate. A first connecting rod is fixedly arranged at one end of the mounting hole on one side of the mounting plate. On both sides of the end of the first connecting rod far away from the mounting plate, brake shoes are movable through the rotating shaft, and high-performance friction plates are fixed on the side of the brake shoe away from the mounting hole, and the brake shoes are far away from the mounting plate. One side of the first connecting rod is installed with the first brake spring through the installation groove on both sides, and the end of the first brake spring far away from the brake shoe is fixedly connected with the end of the first connecting rod far away from the mounting plate. A brake shaft is fixedly arranged at one end of the mounting plate away from the brake shoe. In the present invention, the shoe pin of the brake shoe is a split type and has a roller structure. If the brake breaks down, it can be easily disassembled by the user and convenient for maintenance.

Description

technical field [0001] The invention relates to the technical field of brakes, in particular to a single-shoe pin brake. Background technique [0002] A brake is a device that has the functions of decelerating, stopping or keeping a moving part (or moving machinery) in a stopped state. It is a mechanical part that stops or slows down the moving parts in the machine. Commonly known as brakes, brakes. . [0003] Existing brakes have the following deficiencies: [0004] 1. During the use of existing cars, the wheels are in the air for a long time, and the car will pass through some low-lying areas during driving, so that some water will seep into the inside of the brake. If the brake shoe is in contact with water for a long time It is easy to rust, thereby reducing the service life of the brake. Most of the existing brakes adopt a fully-wrapped shoe pin structure, which is inconvenient for users to disassemble and maintain the brake. [0005] 2. Most existing brakes only u...

Problems solved by technology

[0004] 1. During the use of existing cars, the wheels are in the air for a long time, and the car will pass through some low-lying areas during driving, so that some water will seep into the inside of the brake. If the brake shoe is in contact with water for a long time It is easy to rust, thereby reducing the service life of the brake. Most of the existing brakes adopt a fully-wrapped shoe pin structure. This structure is not convenient for users to disassemble and maintain the brake.

[0005] 2. Most of the existing brakes only use a single brake spring to complete the recovery of the brake after braking. After the brake is used for a long time, the recovery force of a single brake spring may decrease, thereby reducing the recovery effect of the brake shoe
