Abstract

The invention relates to the technical field of drum brakes, and discloses a drum brake shoe with a friction plate convenient to replace. The drum brake shoe with the friction plate convenient to replace comprises a drum shell, wherein a fixing plate is fixedly installed inside the drum shell; a back plate is fixedly installed on the back surface of the drum shell; pressing pins symmetrically distributed on the left and right are fixedly installed on the front surface of the back plate; brake shoes symmetrically distributed on the left and right are movably installed on the outer sides of thetwo pressing pins; wheel cylinders located on the opposite sides of the two brake shoes are fixedly arranged on the front surface of the back plate; supporting pins located on the back surfaces of thetwo brake shoes are fixedly arranged on the front surface of the back plate; and a supporting plate located on the back surfaces of the brake shoes is fixedly arranged on the front surfaces of the supporting pins. The drum brake shoe with the friction plate convenient to replace has the advantages of being convenient for replacing the friction plate and the like, and solves the problem in the prior art that the friction plate is replaced only by dismounting a collar shoe and a slave shoe due to the fact that the friction plate is fixed between the collar shoe and the slave shoe.

Description

technical field [0001] The invention relates to the technical field of drum brake shoes, in particular to a drum brake shoe for easy replacement of friction plates. Background technique [0002] Drum brake shoes are also called brake shoes. Brake shoes are the friction couple of drum brakes. In addition to the strength and rigidity required as a component, the brake shoes should also have as high and stable friction coefficient as possible, and Appropriate wear resistance, heat resistance, heat dissipation and heat capacity, etc., the brake shoes should have appropriate rigidity to withstand the thrust of the actuator, the normal force and tangential force of the brake drum, and the supporting reaction force. The friction plate of the moving shoe is made of different materials according to the different braking devices. [0003] Chinese patent CN201010523567.9 discloses a self-energizing brake, which can automatically realize the adjustment of the upper and lower directions...
