Abstract

The invention discloses an electronic parking actuator for a parking brake system of a motor vehicle. The electronic parking actuator is characterized by comprising a shell, a motor and accessories thereof, a transmission mechanism from a motor shaft to a main shaft of a planetary gear, a large transmission part, a positioning device and a planetary gear mechanism, wherein the transmission mechanism from the motor shaft to the main shaft of the planetary gear is connected with the large transmission part; the large transmission part is positioned and arranged on the positioning device through a positioning pin; the positioning device is provided with a wear-resistant part; the wear-resistant part is a sliding washer or an insert which is made of a metal material; and the axial wear to the transmission part matched with the sliding washer or the insert is reduced by the sliding washer or the insert. The problems of low efficiency and serious wear on a matching part of the positioning device and the transmission part in a thickening scheme in the prior art are solved; and in addition, the electronic parking actuator also has the advantage of high stability.

Description

technical field [0001] The invention is applied to a motor vehicle electronic parking brake system, and belongs to the technical field of design and manufacture of components of a motor vehicle parking brake system.
