Problems solved by technology

[0019] The technical problem to be solved by the present invention is that in the prior art, a belt drive is used between the motor and the planetary gear, and the distance between the motor shaft and the gear shaft is fixed by a technical solution of a rigid spacer. There are rigid spacers and the motor shaft, The inconsistency of the assembly of the main shaft of the planetary transmission mechanism, the axial non-parallel, and the rigid spacer are prone to deformation after being stressed; To solve the technical problems of large external influence, inconsistency of the upper and lower positions of the gear shaft end, and more precise positioning, an electronic parking actuator for the vehicle braking system is provided

Abstract

The invention discloses an electronic parking actuator used for a car braking system. A driving mechanism positioning plate (6) in an integrated structure is arranged, the two ends of the driving mechanism positioning plate (6) are provided with buckles (63) connected with an integrated frame (1), and two fixing points are more accurately positioned through allowance complementation, so that the electronic parking actuator is convenient to install and manufacture, and the cost can be reduced.

Description

technical field [0001] The invention belongs to the technical field of motor vehicle brake system manufacture, and in particular relates to an electronic parking actuator used in the vehicle brake system. Background technique [0002] At present, in the parking brake system of motor vehicles, especially in the electronic parking brake system, the rear caliper integrated electronic parking brake has many functions and is easy to install, which has become a development trend. . The sole power source of the electronic parking brake in this structure is the motor, which transmits power to the brake caliper assembly through the transmission mechanism, and then completes the parking brake of the vehicle. The motor, the transmission mechanism and the housing are collectively referred to as an electronic parking actuator. In the electronic parking actuator, planetary gear transmission is usually used to complete the deceleration of the motor. Due to the small size, light weight an...
