摘要:

根据液压驱动车辆反拖制动的运动特点,分析了液压泵排量对液压驱动车辆下坡制动性能的影响,提出了合理地发挥液压系统和发动机下坡反拖制动能力的原则,并进行了试验验证.结果表明:液压泵排量的大小直接影响着液压系统的制动性能和容积效率,也决定了发动机反拖制动能力的大小以及在液压系统和发动机之间的制动能量分配关系,并影响马达转速的变化.

Abstract:

According to the motion characteristics of anti-drag braking of hydraulically driven vehicles, the influence of hydraulic pump displacement on the downhill braking performance of hydraulically driven vehicles is analyzed, and the principle of reasonably exerting the downhill anti-drag braking ability of hydraulic system and engine is proposed, and experimental verification is carried out. The results show that the size of the displacement of the hydraulic pump directly affects the braking performance and volumetric efficiency of the hydraulic system, and also determines the size of the engine anti-drag braking ability, the braking energy distribution relationship between the hydraulic system and the engine, and affects the change of motor speed.
