Embodiment Construction

[0046] The electronic parking brake actuator (hereinafter referred to as "actuator") according to the present invention generates a large rotational force by decelerating the driving of the motor 30, and transmits the rotational force to the outside, thereby realizing an electronic parking brake. move function. To this end, a motor 30 and a gear assembly 50 are provided inside the actuator assembly of the present invention. The gear assembly 50 described below refers to an integral structure composed of a plurality of gears.

[0047] First, if figure 1As shown, the main housing 10 and the cover 18 combine to form the entire external skeleton of the actuator. When the housing 10 and the cover 18 are combined, a closed installation space 15 is formed inside, and a plurality of components are built in the installation space 15, thereby enabling the actuator to work. When the main housing 10 and the cover body 18 are assembled, only the connector portion 13 and a part of the f...

Abstract

The invention relates to an electronic parking braking executer with double gears. The executer comprises a main housing (10), a motor assembly and a gear assembly (50), wherein a motor arranging part(11) and a gear arranging part (21) are separately formed on the main housing; the motor assembly is arranged on the motor arranging part (11) and provides a rotary force; and the gear assembly (50)rotates by means of the rotary force of the motor assembly and executes a deceleration function through a plurality of gears. According to the invention, not the whole secondary planetary gear bank (70) forming the gear assembly (50) is engaged to an annular gear (60), the first stage is engaged to a last stage gear (53) and the second stage is engaged to the annular gear (60) to rotate. Therefore, not the whole planetary gear bank (70) is restrained on the annular gear (60), so that the gear ratio can be changed freely in a same packaging dimension, and therefore, the degree of freedom in design is further improved.

Description

technical field [0001] The present invention relates to an actuator for performing an operation of an electronic parking brake, and more particularly, to an electronic parking brake actuator capable of passing through an outer final gear constituting a gear assembly. The surface and the inner surface respectively have a double tooth structure of gears different from each other, realizing various gear ratios. 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 ...
