Disc brake for automobile braking system

Abstract

The invention relates to the technical field of automobile spare parts and discloses a disc brake for an automobile braking system. The disc brake comprises a brake disc, the front face of the brake disc is fixedly provided with a wheel flange, the front face of the wheel flange is fixedly provided with a dust cover, and the front face of the wheel flange is fixedly provided with four hub bolts located on the periphery of the dust cover. According to the disc brake for the automobile braking system, a resetting device is movably connected between a first braking friction piece and a second braking friction piece in a sleeved manner, one end of a third nut is connected with a guide pin in a threaded manner, one end of the guide pin is fixedly connected with a gasket in a sleeved manner, theside face of the gasket is movably connected with a first spring in a sleeved manner, the other end of the first spring is fixedly connected with a sliding block, and the sliding block is movably connected outside the guide pin in a sleeved manner. By means of the disc brake, after braking is finished, the first braking friction piece can reset rapidly, the situation that the first braking friction piece continuously rubs with the brake disc to cause abrasion and lower the service life is prevented, therefore the problem that the friction pieces cannot reset rapidly is solved, the service life is prolonged, and the safety of an automobile is improved.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to a disc brake for an auto brake system. Background technique [0002] Automobile braking system refers to a series of special devices that apply a certain force to certain parts of the automobile to perform a certain degree of mandatory braking. The function of the braking system is to make the driving car decelerate or even stop forcibly according to the driver's request, make the stopped car park stably under various road conditions, and keep the speed of the car running downhill stable. [0003] The invention of the existing application number 201280072208.3 discloses a disc brake, a disc brake, in which the brake caliper is supported on a mounting bracket via a sliding pin, and the mounting bracket is fixed to a non- The rotating part, the disc brake, is characterized by having an electromagnet provided with respect to the slide pin and attracting the slide pin in the axia...

AI Technical Summary

Problems solved by technology

[0009] Aiming at the deficiencies of the prior art, the present invention provides a disc brake for an automobile braking system, which has the advantages of automatic reset of the friction plate after braking, easy disassembly and replacement of the friction plate, and easy adjustment of the position of the floating mechanism. The friction plate is not reset quickly enough, it is not convenient to disassemble and replace the friction plate, and the position of the floating mechanism cannot be adjusted.
