Abstract

The invention provides an actuating mechanism for an electronic parking brake. The actuating mechanism comprises an upper cover, a shell and a lower shell. The upper cover and the lower cover are arranged at the upper end and the lower end of the shell correspondingly, a hollow cavity is formed, a motor, a transmission mechanism and a planetary reducing mechanism are contained in the cavity, the motor and the planetary reducing mechanism are arranged in the cavity of the shell correspondingly, and the motor is parallel to a center shaft of the planetary reducing mechanism, the transmission mechanism comprises a first synchronous belt wheel, a second synchronous belt wheel and a belt, and the motor sequentially passes through the first synchronous belt wheel, the belt and the second synchronous belt wheel to be connected with the planetary reducing mechanism to transfer torque. The actuating mechanism for the electronic parking brake is simple in structure, capable of achieving the simple structure and technology, low in cost, wide in application range, and used for a vehicle brake system.

Description

technical field [0001] The invention relates to the field of motor vehicle braking systems, in particular to an actuator for electronic parking brakes. Background technique [0002] In recent years, in the field of motor vehicle braking systems, the electronic parking brake ((EPB, Electrical ParkBrake) has more and more replaced the traditional mechanical integrated parking brake due to its convenience and comfort in market applications. Brake (IPB) and disc-in-drum brake (DIH). The traditional mechanical integrated parking brake (IPB) and disc-in-drum brake (DIH) structure drives the cable through the handbrake mechanism, thereby driving the parking mechanism to park The handbrake force is converted to the clamping force of the brake, which is pressed onto the disc. [0003] However, the Electronic Parking Brake (EPB) replaces the traditional mechanical parking structure that applies the parking brake force, which can greatly improve the performance of the parking system b...
