本发明公开了一种制动控制系统,包括阀体、位于阀体内的第一集气腔和第二集气腔、进气口、出气口,进气口与第二集气腔之间通过第一流道连通,还包括位于阀体内的活塞腔、与活塞腔相匹配的活塞、与活塞相连的阀杆、位于阀杆上的第一限位装置和第二限位装置,活塞将活塞腔分隔为限压腔、行程腔,阀杆一端与活塞固定连接、另一端穿过第二集气腔进入第一集气腔内部;还包括连通限压腔与第二集气腔的第二流道,第二流道内设置单向阀,单向阀沿限压腔至第二集气腔方向导通。本发明可解决现有技术中限压腔室内部的压力上升速度极快,不利于对制动系统的精确控制的问题,实现在不降低制动控制输出流量的前提下,使限压腔室内部压力平稳升高的目的。

    The invention discloses a brake control system which comprises a valve body, a first gas collecting cavity, a second gas collecting cavity, a gas inlet and a gas outlet. The first gas collecting cavity and the second gas collecting cavity are located in the valve body. The piston cavity is located in the valve body, the piston is matched with the piston cavity, the valve rod is connected with the piston, the first limiting device and the second limiting device are located on the valve rod, the piston cavity is divided into a pressure limiting cavity and a stroke cavity by the piston, one end of the valve rod is fixedly connected with the piston, and the other end of the valve rod penetrates through the second gas collecting cavity to enter the first gas collecting cavity; the second flow channel is communicated with the pressure limiting cavity and the second gas collecting cavity, a one-way valve is arranged in the second flow channel, and the one-way valve is communicated in the direction from the pressure limiting cavity to the second gas collecting cavity. The problem that in the prior art, the pressure in the pressure limiting cavity rises extremely fast, and accurate control over a brake system is not facilitated can be solved, and the purpose that the pressure in the pressure limiting cavity rises stably on the premise that the brake control output flow is not reduced is achieved.
