Parking brake device and parking brake system

Abstract

A parking brake device, comprising a transmission mechanism and a brake caliper that is transmission-connected to the transmission mechanism; the transmission mechanism includes a housing provided with an installation through hole and an installation cavity, located in the installation through hole and provided with a driven A planetary reducer with a synchronous pulley and a floating centering shaft, a motor located in the installation cavity and with a positioning bead on the front cover, a positioning hole sleeved outside the positioning bead, and snaps on opposite sides of the positioning hole. The lower connection block of the hole and the buffer hole is equipped with a block inserted into the hole, an insert piece wrapped around the buffer pad and inserted into the buffer hole, and an upper part of the radial limit hole that is matched with the front end of the floating centering shaft. The connecting block, the shell cover connected with the housing, the elastic damping block connected with the front end of the lower connecting block and the shell cover respectively, the active synchronous pulley and the synchronous belt connected with the output shaft of the motor. When the parking brake device works, the vibration and noise are small and the assembly is easy.

Description

technical field [0001] The invention relates to the field of automobile brake devices, in particular to a parking brake device and a parking brake system. Background technique [0002] The parking brake of the car is applied to the parking brake cable by pulling the parking brake lever, and the movement of the vehicle is restrained by operating the parking brake device. The operation is laborious, and it is necessary to rely on the driver when starting on a slope. Only by manually releasing the handbrake and skilled accelerator and clutch cooperation can a smooth start be made; the invention of Chinese patent application number: 200610062108.9 discloses a parking brake system, including a parking operating part located in the cab, and a vehicle The power output shaft of the parking brake assembly directly engaged, is characterized in that: the parking brake assembly includes a first one-way overrunning clutch and a second one-way overrunning clutch, and the two one-way overr...
