| 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 characteristics of the hydraulic driving vehicle in anti-dragged brake course,this paper analyzes the influence of pump range on anti-drag brake performance.The proper use of the anti-dragged brake power of the hydraulic system and engine is recommended on the basis of experimental validation.The results indicate that the pump range affects not only the brake stopping power and volumetric efficiency of hydraulic system,but also the anti-dragged brake power of the engine.The pump ranges determine allocation of brake energy between hydraulic system and engine and also influence the motor speed. |
