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 brake pressure required by the driver; The same pedal pressure as a conventional brake.

[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 sea...
