Parking baseplate assembly of drum-in-disc type parking brake

Abstract

The invention discloses a parking baseplate assembly of a drum-in-disc type parking brake, which comprises a baseplate body, a dust cover and a pulling-rope conduit arranged on the baseplate body, and the baseplate body, the dust cover and the pull conduit are made from engineering plastics or carbon fibers. Because the parts are made from the engineering plastics or the carbon fibers with high temperature resistance, corrosion protection, good weatherability and flame resistance to substitute metal materials used in the prior art, the cost of the materials and machining is lower; the weight of the parts is decreased; the problem of easy corrosion of the metal materials is solved while effectively meeting the requirements for the functions and the performance of the baseplate assembly of the drum-in-disc type parking brake; the process for producing the parts is simpler than the processes for pressing, welding and riveting the metal materials, and the like; the production cycle is shortened effectively; and the production efficiency is enhanced. Moreover, the parking baseplate assembly also has the effects on reducing noise and improving weatherability, and greatly enhances the stability of the braking performance of the parking brake.

Description

technical field [0001] The invention relates to a parking brake part of a vehicle, in particular to a parking floor assembly of a drum-in-disc parking brake. Background technique [0002] The parking brake usually refers to the manual brake installed on the motor vehicle, referred to as the hand brake, which is used to stabilize the vehicle after the vehicle has stopped, so as to avoid accidents caused by rolling when the vehicle is parked on a slope. [0003] In the prior art, the parking floor assembly of the disc drum brake of a vehicle is mainly composed of a parking floor, a dust cover, and a drawstring guide plate. Usually, they are stamped and formed by metal plates and then welded or riveted. Combined, and finally the surface is painted for anti-rust treatment. Because the parking floor assembly is composed of sheet metal parts, it has the following disadvantages: the stamping forming and welding (riveting) processes are complicated, resulting in a long process cycl...

AI Technical Summary

Problems solved by technology

Because the parking floor assembly is composed of sheet metal parts, it has the following disadvantages: the stamping forming and welding (riveting) processes are complicated, resulting in a long process cycle and low production efficiency; the metal parts are prone to rust, which makes the parking floor assembly Low anti-rust ability; In addition, materials and processes also determine that disc drum brakes are prone to abnormal noise during use, and the production cost is relatively high
