Abstract

An electric booster having a force-feedback-control structure is provided. The electric booster includes a master piston having a nut unit rectilinearly moved in a booting cylinder space by receivingdriving power generated by a motor and a hydraulic pressure generated by a pedal effort. A first screw has a first end connected to the motor and a second end extending into the boosting cylinder, andis rotated by the motor operating with the brake pedal. A second screw is disposed to face the first screw to have a separation space. A connecting member connects the first screw and the second screw. A pressure balancing member has contact surfaces in contact with the second end of the first screw and the connecting member, respectively, and is deformed by a difference between two pressures when applied to the contact surfaces in a longitudinal direction of the first screw, respectively.

Description

[0001] Cross References to Related Applications [0002] This application claims priority under 35 U.S.C. §119 to Patent Application No. 10-2019-0058980 filed with the Korean Intellectual Property Office on May 20, 2019, the entire contents of which are incorporated herein by reference. technical field [0003] The present invention relates to an electric booster with a force feedback control structure, more particularly, to such an electric booster with a force feedback control structure, which can apply pressure feedback by receiving pressure feedback from the outside of the cylinder and comparing The pressure balance is adjusted by the pedal force to the brake pedal and the force generated by the electric motor. Background technique [0004] Generally, in an electric power-assisted braking system, when the driver engages the brake pedal, the pedal force sensor detects the driver's pedal force (for example, the amount of force applied to the pedal), and the electronic cont...
