The invention relates to the technical field of braking, in particular to a valve body assembly, a braking system and a motorcycle. The valve body assembly comprises a main body, a pressure increasing valve, a pressure release valve and an oil scavenging pump; the main body is provided with an oil inlet, an intercepting hole and an oil storage cavity; the intercepting hole is communicated with the oil storage cavity, and the hole diameter of the intercepting hole is 0.4 mm; the pressure increasing valve, the pressure release valve and the oil scavenging pump are connected with the main body; the oil inlet is communicated with the pressure increasing valve; the pressure release valve is communicated with the intercepting hole; the oil return pump is communicated with the oil storage cavity; wherein the oil inlet and the oil return pump are both used for being communicated with an external main cylinder pipeline, and the pressure increasing valve and the pressure release valve are both used for being communicated with external calipers. According to the valve body assembly, the 0.4 mm throttling hole is additionally formed in the valve body assembly in a machining mode, so that when the pressure relief valve conducts pressure relief on calipers, the pressure relief amount of the pressure relief valve is controlled through the phi 0.4 intercepting hole, and therefore the requirement for a valve hole of the pressure relief valve is reduced, the development period of a new product is shortened, and the development cost and the production cost are reduced.
本发明涉及制动技术领域,具体而言,涉及一种阀体组件、制动系统和摩托车。阀体组件包括主体、增压阀、泄压阀以及回油泵;主体开设有进油口、截流孔以及蓄油腔;截流孔与蓄油腔连通,且截流孔的孔径为0.4mm;增压阀、泄压阀及回油泵均与主体连接;进油口与增压阀连通;泄压阀与截流孔连通;回油泵与蓄油腔连通;其中,进油口及回油泵均用于与外部的主缸管路连通,增压阀及泄压阀均用于与外部的卡钳连通。该阀体组件通过机加的方式新增一个0.4mm的节流孔,以在泄压阀对卡钳进行泄压时,通过φ0.4的截流孔对泄压阀的泄压量进行控制,从而减少对泄压阀的阀孔的要求,以缩短新品的开发周期,降低开发成本和以及生产成本。
