Abstract

The invention discloses an electronic parking executor 1 applied to a motor vehicle brake system, which comprises a shell, a cover, a motor, motor accessories, a planetary gear transmission mechanism, parking brake calipers and the like. The electronic parking executor also comprises an integrated transmission mechanism frame, wherein a transmission mechanism and a planetary gear transmission mechanism from a motor shaft and a planetary gear main shaft are installed on a body in the integrated transmission mechanism frame, and the power transmission route of the transmission mechanism is from the motor shaft to the planetary gear main shaft. The technical scheme provided by the invention can effectively solve the problems of inconsistent assembly between rigid spacers and the motor shaft and the main shaft of the planetary gear transmission mechanism, axial nonparallelism and easy deformation of the rigid spacers after stressing in the prior art; meanwhile, the invention also has the characteristics of increasing the stability of internal transmission mechanism and the performance consistency after being connected with braking, reducing assembly cost, increasing assembly quality, benefiting tests, having good batch consistency and the like.

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 motor vehicle parking 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, l...
