Problems solved by technology

[0009] However, a plurality of gear units installed for power transmission has a disadvantageous effect in terms of operating noise when braking
For example, inaccurate control of the coupling (engagement) between gears when the actuator is operating may lead to the generation of noise and vibration and in more serious cases may reduce the durability of the actuator

Abstract

Disclosed is an electronic disc brake. The electronic disc brake includes a disc configured to rotate with vehicle wheels, a caliper housing configured to operate pad plates installed at both sides of the disc, and an actuator having a piston provided inside the caliper housing to press the pad plates to adhere the pad plates to the disc, a spindle rotatably installed at the caliper housing to reciprocate the piston, an electric motor configured to rotate the spindle, and a decelerator configured to transmit a rotational force of the electric motor to the spindle, wherein the decelerator includes a power connection unit connected to the electric motor, planetary gear units configured to connect the power connection unit to the spindle, and a center pin configured to pass through the power connection unit and the planetary gear units, and the center pin is fitted into the power connection unit and the planetary gear units to be rotatable relative thereto.

Description

[0001] Cross references to related applications [0002] This application claims the rights and interests of the Korean patent application with application number 2015-0133874 filed with the Korean Intellectual Property Office on September 22, 2015, the disclosure of which is incorporated herein by reference. Technical field [0003] The present disclosure relates to an electronic disc brake, and more particularly to an electronic brake system capable of realizing a parking function through the operation of an electric motor. Background technique [0004] Generally, the brake device is a device for stopping the vehicle when the vehicle is braked or parked to prevent the vehicle from moving and for holding the wheels of the vehicle to prevent the wheels from rotating. [0005] An electronic parking brake (EPB) system that electronically controls the operation of the parking brake is currently widely used and installed on a typical disc brake to perform the function of the parking brake...
