The invention provides a commercial vehicle brake pedal force control system and a vehicle, and belongs to the technical field of vehicle development, the system comprises a brake pedal, a brake valve push rod, a brake valve, a rear air reservoir, a front air reservoir, a front loop pressure limiting valve, a rear loop pressure limiting valve, a front axle relay valve and a rear axle relay valve; compressed air in the front air storage cylinder enters the brake valve through the front loop pressure limiting valve and the first air inlet; compressed air in the rear air storage cylinder enters the brake valve through the rear loop pressure limiting valve and the second air inlet; when the brake pedal is stepped down, the brake valve push rod moves, and compressed air in the brake valve is discharged to the rear axle relay valve and the front axle relay valve from the first air outlet and the second air outlet; and when the brake pedal returns, the brake valve push rod returns, and compressed air in the brake valve is discharged into the atmosphere from the first air outlet and the second air outlet. On the premise that a commercial vehicle assembly is not changed, the brake pedal force is reduced, and the design and manufacturing cost and difficulty for reducing the brake pedal force are reduced.
本发明提供了一种商用车制动踏板力控制系统及车辆,属于车辆开发技术领域,其系统包括:制动踏板、制动阀推杆、制动阀、后贮气筒、前贮气筒、前回路限压阀、后回路限压阀、前桥继动阀及后桥继动阀;前贮气筒中的压缩空气经前回路限压阀和第一进气口进入制动阀;后贮气筒中的压缩空气经后回路限压阀和第二进气口进入制动阀;当制动踏板被踩下时,制动阀推杆移动,制动阀中的压缩空气从第一出气口和第二出气口排出至后桥继动阀和前桥继动阀;当制动踏板回位时,制动阀推杆回位,制动阀中的压缩空气从第一出气口和第二出气口排出至大气中。本发明实现了在不改变商用车总成的前提下降低制动踏板力,降低了实现降低制动踏板力的设计制造成本和难度。
