The invention provides a floating structure of a brake valve, and belongs to the technical field of hydraulic braking. The problem that an existing brake valve is low in response timeliness is solved. The floating structure of the brake valve comprises a valve body, a main piston and an auxiliary piston capable of moving towards the main piston are arranged in an inner cavity of the valve body in a penetrating mode, the main piston is provided with an oil return flow channel communicated with an oil return hole, the auxiliary piston is provided with an oil passing flow channel communicated with the inner cavity of the valve body and the oil return flow channel, and a first one-way assembly is arranged in the oil passing flow channel. The floating structure further comprises a valve element arranged between the main piston and the auxiliary piston, a floating spring abutting against the auxiliary piston is arranged on the valve element, the auxiliary piston can drive the valve element to move, the valve element abuts against the main piston to block the oil return flow channel, and the first one-way assembly is opened through the valve element. The floating structure of the brake valve has the advantage of improving the response timeliness of the brake valve.

    本发明提供了一种制动阀的浮动结构,属于液压制动技术领域。它解决了现有制动阀响应及时性低的问题。本制动阀的浮动结构包括阀体,阀体内腔穿设有主活塞和能朝主活塞移动的辅助活塞,主活塞具有与回油孔连通的回油流道,辅助活塞具有连通阀体内腔和回油流道的通油流道,通油流道内设有第一单项组件,浮动结构还包括设于主活塞与辅助活塞之间的阀芯,阀芯上设有抵靠辅助活塞的浮动弹簧,辅助活塞能带动阀芯移动,使阀芯与主活塞抵靠以封堵回油流道,并通过阀芯开启第一单项组件。本制动阀的浮动结构具有提高制动阀响应及时性的优点。
