Problems solved by technology

[0004] In cases where multiple pistons are provided and these pistons receive driving force from a single actuator, the load may not be transferred uniformly to the multiple pistons
In this case, uneven wear of the friction lining may result, and braking performance may deteriorate

Abstract

A parking brake device for a vehicle includes: a motor component receiving electric power from outside and generating power; a power transmission member that is driven by the motor member to rotate; a pair of pressing units receiving power from the power transmission member and pressing a brake pad; a load transmission unit installed between the pair of pressing units, connected to each of the pair of pressing units, and transmitting a pressing load of any one of the pair of pressing units to the other pressing unit; and a transmission gear member constraining unit that selectively constrains driving of the load transmission unit in conjunction with rotation of the power transmission member.

Description

technical field [0001] Exemplary embodiments of the present disclosure relate to a parking brake device for a vehicle, and more particularly, to a parking brake device for a vehicle capable of uniformly transmitting a load to a brake pad (brake pad). Parking brake. Background technique [0002] Generally, an actuator of an electric parking brake system for a vehicle is composed of an electric motor and a power transmission device for operating a friction plate installed in a caliper of a disc brake device during parking. [0003] When the driver pushes the parking brake switch, the rotational force of the motor of the actuator is transmitted to the input shaft of the caliper through a power transmission device such as a reduction gear. The pressure connection sleeve is moved forward by the rotation of the input shaft, and by the forward movement of the pressure connection sleeve, the caliper housing and the piston accommodating the pressure connection sleeve are moved towar...
