The invention relates to the technical field of vehicle control, in particular to a hydraulic load sensing proportional valve and a brake system for a vehicle, which comprise a shell, a front piston, a front piston elastic piece, a one-way valve elastic piece and a one-way valve ball, the front piston is arranged in the front chamber through a front piston elastic piece; the one-way valve elastic piece provides elastic force enabling the one-way valve ball to move towards the valve port so as to seal the valve port. And a rear piston, a rear piston elastic piece, an adjusting screw rod, an adjusting screw rod elastic piece, a load sensing elastic piece seat and a load sensing compression elastic piece. The rear piston comprises a body and a piston column; the piston column penetrates through the matching channel and enables the one-way valve ball to be away from the valve port. The end of the adjusting screw rod penetrates through the rear cavity to abut against the body of the rear piston. The adjusting screw elastic piece provides elastic force so that the adjusting screw can move towards the rear piston. The load sensing compression elastic piece provides elastic force which enables the adjusting screw rod and the load sensing elastic piece seat to be far away from each other. Thus, front and rear wheel braking system hydraulic pressure can be dynamically distributed.

    本发明涉及车辆控制技术领域,具体而言,涉及一种车辆用液压感载比例阀和制动系统,其包括壳体,前活塞、前活塞弹性件、单向阀弹性件和单向阀球;前活塞通过前活塞弹性件设置在前腔室中;单向阀弹性件提供以使单向阀球朝向阀口移动以密封阀口的弹性力;以及后活塞、后活塞弹性件、调节螺杆、调节螺杆弹性件、感载弹性件座、感载压缩弹性件;后活塞包括本体和活塞柱;活塞柱穿设配合通道,且能够使单向阀球远离阀口;调节螺杆的端部穿设后腔室以抵持在后活塞的本体上;调节螺杆弹性件提供弹性力以使调节螺杆朝向后活塞移动;感载压缩弹性件提供以使调节螺杆与感载弹性件座相互远离的弹性力。如此能够动态分配前后轮制动系统液压。
