Abstract

Disclosed herein is an electric caliper brake. Then electric caliper brake which includes a carrier provided with a pair of pad plates movably with respect to a disk, and a caliper housing slidably installed on the carrier and provided with a cylinder in which a piston is movably provided by braking oil pressure, includes a spindle member which is installed to penetrate a rear portion of the cylinder and rotates by receiving a rotational force from an actuator, and a power converting unit including a nut member which is screwed with the spindle member and is disposed in the piston, moves forward and backward in accordance with the rotation of the spindle member so as to press the piston; a filling member coupled to the nut member in the piston; and an anti-rotation surface provided on at least one plane on an outer circumferential surface of the filling member so that the filling member is coupled to the piston in a limited rotation state.

Description

technical field [0001] The present invention relates to an electric caliper brake, and more particularly, to an electric caliper brake capable of simplifying the structure and improving operating efficiency. Background technique [0002] Generally, the electric caliper brake is adopted by adding an electric brake to the usual hydraulic disc brake. [0003] An example of such an electric disc brake (hereinafter, referred to as an "electric caliper brake") is disclosed in Korean Laid-Open Patent No. 10-2011-0124817. According to the disclosed document, the electric caliper brake includes: a disc, which rotates together with the wheels of the vehicle; It is slidably provided on the carrier, and has a cylinder in which a piston can advance and retreat by brake hydraulic pressure; a main shaft, which pressurizes the piston; and a motor and a reducer as a brake, which transmit the rotational force. [0004] Such an electric caliper brake performs a braking action by pressurizin...
