The invention discloses a vehicle integrated type electro-hydraulic braking system device which comprises a liquid storage tank used for storing a pressurizing fluid; a pedal for operating a braking action; a brake master cylinder, a piston of which is fixedly connected with the pedal operating handle and used for providing initial brake pressure, and a left cavity liquid inlet and a right cavity liquid inlet of the same are connected with an oil inlet and an oil outlet of a liquid storage tank respectively. During conventional braking, a driver steps on the liquid storage tank, and the displacement sensor collects signals and transmits the signals to the ECU; afterwards, the ECU sends instruction signals to all valve modules, a first master cylinder decoupling valve and a second master cylinder decoupling valve are powered on and disconnected, a motor in a servo master cylinder rotates to build pressure in the servo master cylinder, and high-pressure brake fluid is pumped into a wheel cylinder set through a transmission mechanism; due to the fact that the first motor decoupling valve and the second motor decoupling valve are of a one-way valve pure mechanical structure, the adaptability to working conditions is high, and the problem of electromagnetic valve faults is effectively solved.
本发明公开了一种车辆集成式电液制动系统装置,包括:储液罐,其用于存储加压介质;踏板,其用于操作刹车动作;制动主缸,其活塞与所述踏板操作柄固定连接用于提供初始刹车压力,所述制动主缸的左腔进液口和右腔进液口分别与储液罐的进油口和出油口连接。本发明在常规制动时,驾驶员踩下储液罐,位移传感器采集到信号输送到ECU,ECU向各阀模块发出指令信号,第一主缸解耦阀和第二主缸解耦阀上电断开,伺服主缸中电机转动在伺服主缸中建压,通过传动机构将高压制动液泵入到轮缸组,因为第一电机解耦阀和第二电机解耦阀采用单向阀纯机械结构,则对工况适应能力强,也有效解决电磁阀故障问题。
