Problems solved by technology

When the center distance between the rotating axes deviates from the allowable range due to accumulated tolerances between parts, there may be quality problems such as performance degradation or noise generation
In particular, motor vibration generated during operation due to such accumulated tolerances causes rattling of parts such as gears, and reduces the durability of the gears, thereby reducing the durability of the product
[0004] This is because, when assembling various components such as the built-in motor and gears, it is difficult to precisely align the shafts between the various components, especially, the gear assembly (or gearbox) for performing the deceleration function is an additional structure different from the motor assembly , which increases the internal structure, makes tolerance management difficult due to tolerance build-up, and therefore makes it more difficult to align axes between parts that are spaced apart from each other
[0005] In addition, since the actuator has a large number of built-in parts, the number of processes required to assemble each part increases, resulting in an increase in manufacturing time and manufacturing costs.

Abstract

An electric parking brake actuator assembly is proposed. The electric parking brake actuator assembly includes: an outer housing (10) including an inner space (10') in which a gear installation space(14) and a motor installation space (12) are formed; an inner housing (30) installed in the inner space (10') of the outer housing (10), and including a brush card part (31) and a gear installation part (34) integrated together; a motor assembly (1) coupled to the brush card part (31) to be electrically connected thereto, and installed in the motor installation space (12); a gear assembly installed at the gear installation part (34) and at the gear installation space (14), and changing and transmitting the rotational speed of the motor assembly (1); and a cover housing (20) coupled to the outer housing (10) with the inner housing (30) interposed therebetween, and including a shaft insertion portion.

Description

technical field [0001] The present invention relates to an electronic parking brake actuator assembly, in more detail, relates to an electronic parking brake actuator assembly with simplified internal structure. Background technique [0002] The electric 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. 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 assembly (power transmission device) such as a reduction gear. Input shaft. When the input shaft receiving ...
