Abstract

The present invention relates to an electronic hydraulic brake device which includes a master housing unit where fluid providing fluid pressure to a wheel is stored; a master piston unit which is inserted into the master housing unit; an elastic unit which is embedded inside the master housing unit and which elastically supports the master piston unit; a pedal housing unit joined to the end portion of the master housing unit; a damper cylinder unit inserted into the pedal housing unit; a piston rod unit which is pin-joined to the damper cylinder unit and which transmits a pressing force of a pedal; a guide rod unit which is screw-joined to the damper cylinder unit; and a damper unit which is joined to the guide rod unit and inserted into the master piston unit, thereby reducing the number of components and the sense of difference of a feeling of stepping the pedal.

Description

technical field [0001] The present invention relates to an electrohydraulic brake device, and more specifically, to an electrohydraulic brake device that improves assembly and alleviates the difference in pedal feel between a normal state and an emergency state. Background technique [0002] Usually, the electronic hydraulic brake device uses a hydraulic modulator to adjust the brake pressure of each wheel after the sensor senses the pedal pressure applied by the driver. [0003] This electronic hydraulic brake device is equipped with a sensor for the vehicle pedal travel distance to understand the braking pressure required by the driver; the same pedal pressure as the actuator. [0004] figure 1 is a diagram schematically showing a conventional electronic hydraulic brake device. [0005] refer to figure 1 , the master cylinder body 111 and the simulator body 113 are assembled by bolts, and the inner side of the master cylinder piston 112 is installed through a sealing c...
