Abstract

The invention relates to an electronic parking brake actuator with a brush plate integrated housing. The actuator is provided with a main case (10) in which a motor installation part (11) and a gear installation part (21) are formed; a motor assembly (23) that is provided to the motor installation part (11) and that supplies a rotational force; a gear assembly (50) that rotates by the rotational force of the motor assembly (23) and performs a deceleration function by a plurality of gears; and an inner housing (30). The inner housing (30) is assembled to the main case (10) to fix the gear assembly (50), and is integrally provided with a ring gear interlocked with a planetary gear set (70) constituting the gear assembly (50), and a brush plate electrically connected to the motor assembly (23).

Description

technical field [0001] The present invention relates to an actuator for operating an electronic parking brake, and more particularly, to an electronic parking brake in which a ring gear and a brush card are integrally formed in a gear box provided inside. Actuator for electromechanical parking brake. Background technique [0002] The electronic parking brake actuator of the automobile operates the friction pads of the calipers (Caliper) provided on the disc brake (disc brake) device when the vehicle is parked. The electronic parking brake is automatically operated by a user's switch operation, and for this purpose, is composed of an electronic parking brake motor and a gear assembly (power transmission device) for transmitting power of the motor. [0003] In the case of using the electronic parking brake as described above, when the driver presses the parking brake switch, the rotational force of the motor of the actuator is transmitted to the caliper through a gear assembl...
