The invention relates to an electronic control actuating mechanism for parking brake. The electronic control actuating mechanism for parking brake comprises a speed reducing and torque increasing device, a motor, a positioning and vibration reducing device and a lower shell, wherein the speed reducing and torque increasing device is used for reducing revolving speed and increasing torque; the motor is used for providing power for an electronic control actuating unit; the positioning and vibration reducing device is used for keeping a center distance between the motor and the speed reducing and torque increasing device and retarding impact vibration in a using process of the actuating mechanism; and the lower shell and an upper shell form an accommodating cavity which is used for accommodating the speed reducing and torque increasing device, the motor and the positioning and vibration reducing device. By the electronic control actuating mechanism with the structure, stability of the center distance can be guaranteed reliably, axial height of a parking actuating unit can be reduced, application range of the parking actuating unit is expanded, and risks of low efficiency, shortened service life, transmission abnormal sound and even jamming which are caused by unparallel positioning when rigid connectors are used are avoided.
Description
technical field [0001] The invention relates to the technical field of vehicle braking, in particular to the technical field of parking brake systems of traditional motor vehicles and electric vehicles, and specifically refers to an electronically controlled actuator for parking brakes. Background technique [0002] The traditional vehicle parking brake system (also known as "hand brake") operates the parking handle through the driver, and the parking handle drives the parking cable to drive the rear axle brake or the central brake, thereby generating a braking torque that acts on the rear axle. The axle wheel realizes the parking brake of the vehicle. [0003] The parking method in the form of the hand brake has been used by people all the time, but there may be a safety hazard in the parking mechanism of this method, because different drivers have different forces to manipulate the parking lever, which will lead to the same The parking brake torque produced by different d...
