摘要： Provided is an actuator assembly with an integrated housing for an electromechanical parking brake. The actuator assembly includes: a main housing having an integrated motor seat and an integrated gear set; a motor assembly disposed in the motor seat and providing torque; a gear assembly rotated by the torque from the motor assembly and performing a reduction function through a plurality of gears; a stator part constituting the motor assembly and at least partially formed on the inner side of the motor seat by insert injection molding; and a ring gear integrally formed with the gear seat or formed by insert injection molding and operating the gear assembly. The stator part of the motor assembly and the ring gear of the gear assembly are integrally formed with the main housing in the actuator assembly.
