The invention relates to the technical field of vehicle braking, in particular to a hydraulic distribution valve and a vehicle braking system. The hydraulic distribution valve comprises a valve body, a plunger and a first sealing piece. The first sealing piece is connected to the inner wall of the main cavity; the plunger is movably arranged in the main cavity in the axis direction of the main cavity and penetrates through the first sealing piece. The plunger is used for moving from the first chamber to the second chamber under the action of the oil pressure in the first chamber, so that the second oil port is blocked from the second chamber, and the oil pressure in the second chamber is pressed into the third oil port; or the plunger is used for moving from the second chamber to the first chamber under the action of the oil pressure in the second chamber, so that the second oil port and the third oil port are both communicated with the second chamber. The hydraulic distribution valve is applied to a vehicle braking system, the internal structure of the hydraulic distribution valve can be simplified on the basis that the using performance is guaranteed, then the assembling period can be shortened, the assembling difficulty can be reduced, and the manufacturing and using cost can be reduced.

    本发明涉及车辆制动技术领域,具体而言,涉及一种液压分配阀和车辆制动系统。液压分配阀包括阀体、柱塞及第一密封件;第一密封件连接于主腔的内壁;柱塞沿主腔的轴线方向可活动地设置于主腔,且穿设于第一密封件;柱塞用于在第一腔室中的油压的作用下,由第一腔室朝向第二腔室的方向运动,以使得第二油口与第二腔室阻断,且将第二腔室中的油液压入第三油口;或,柱塞用于在第二腔室中的油压的作用下,由第二腔室朝向第一腔室的方向运动,以使得第二油口及第三油口均与第二腔室连通。该液压分配阀应用于车辆制动系统,其能够在保证使用性能的基础上,简化其内部结构,进而能够缩短装配的周期和降低装配难度,并降低制作和使用的成本。
