Brake shoe wear automatic compensation device for hydraulic disc brake

Abstract

The invention discloses a brake shoe wear automatic compensation device for a hydraulic disc brake, which comprises a rack. An oil cylinder is arranged on the rack; a cylinder cover is arranged on the end surface of one side of the oil cylinder; a brake shoe is arranged outside the end surface of the other side of the oil cylinder; the brake shoe mainly consists of a brake seat and a brake rubber block; the brake rubber block is arranged on the brake seat; a piston is arranged in the middle position of the oil cylinder; one end of the piston is provided with a rotating rod, and the other end of the piston is mounted with a piston rod; the brake seat is connected with the piston rod in a sleeving way; a brake spring is arranged between the piston and the brake seat; the front end of the cylinder cover is provided with an end cover; an automatic detection mechanism is arranged between the end cover and the oil cylinder; a transmission mechanism is arranged on the end cover; and one end of the transmission mechanism is in contact with the automatic detection mechanism, and the other end of the transmission mechanism is connected with the rotating rod. The brake shoe wear automatic compensation device for the hydraulic disc brake avoids brake failure caused by continuous wear to the brake shoe in the operating process.

Description

technical field [0001] The invention relates to a hydraulic disc brake, in particular to an automatic compensation device for brake shoe wear of the hydraulic disc brake. Background technique [0002] Hydraulic disc brakes are usually composed of a friction pair, a force device and a brake release device. The friction pair is composed of a brake disc and a friction disc. The working surface is the two sides of the friction disc. The force device usually uses a special butterfly spring. Hydraulic disc brakes usually adopt a normally closed design, which is safe and reliable. The so-called brake shoes are tile-shaped brake blocks made of cast iron or other materials, which hold the wheel tread tightly during braking and stop the wheel through friction. [0003] The hydraulic disc brakes currently used in industrial sites often rely on hydraulic pressure to release the brakes and spring force to lock the brakes to achieve braking conditions. In the process of using hydraulic d...
