Embodiment Construction

[0037] Figures 1 to 10 An example of an embodiment of the invention is shown. In this embodiment, a case is shown in which the present invention is applied to a drum-in-disk brake. The drum brake type electric parking brake device of this embodiment has a steering knuckle 1, a brake base plate 2, a pair of brake shoes 3, 3, a drum (not shown), an anchor bracket 4 and an electric actuator unit 5 .

[0038] The steering knuckle 1 constitutes a suspension of the vehicle, and has a frame portion 6 having a frame shape. The wheels are rotatably supported on the outer side surface of the frame portion 6 by a hub unit (not shown). The hub unit may be a double row rolling bearing unit for wheel support. The hub unit combines and fixes a fixing flange fixed on the outer peripheral surface of the outer ring as a non-rotating ring to the frame portion 6 by bolts; and the hub unit combines a wheel and a drum (not shown) to the rotating A flange, which is a rotating flange, is provid...

Abstract

A drum brake type electric parking brake device is provided, including an electric actuator unit, a brake base plate, and a steering knuckle. The electric actuator unit includes an electric motor and a speed reducer, and expands a gap between one end portions of the brake shoes based on the actuation of the electric motor. The electric actuator unit is provided separately from the brake shoe. The electric actuator unit is arranged at an inner side surface of a steering knuckle, and the brake shoe is arranged at an outer side surface of the steering knuckle. The brake shoe and the electric actuator unit are supported and fixed to the steering knuckle.

Description

technical field [0001] The present invention relates to a drum brake type electric parking brake device which expands a gap between a pair of brake shoes by an electric motor to generate a braking force. Specifically, the present invention relates to a drum brake type electric parking brake device capable of realizing a structure that can reduce the number of parts thereof, thereby reducing the cost of the device. [0002] In addition, the drum brake type electric parking brake device which is the subject of the present invention includes not only both of the service brake in which the drum brake is used to decelerate or stop the vehicle from the running state and the parking brake for maintaining the stopped state It also includes drum-in-disk brakes, where the disc brake is used for service braking and only the drum brake is used for parking braking. Background technique [0003] Embedding the parking brake in the drum brakes keeps the vehicle at a stop without pressing t...
