摘　　要：对某型车液压系统在进行备胎架的收放过程中岀现冲击振动大、运动不稳定等现象产生的原因进行了研究分析,并对该备胎架收放装置液压系统进行了优化改造。结果表明,在液压系统中增加平衡阀可有效解决备胎架运动的不稳定问题。This paper studies and analyzes the causes for large impact vibration and unstable motion of the hydraulic system of a vehicle during the retracting and extending process of spare tire carriers,and provides the optimization and modification of the hydraulic system of the retracting and extending device.The result shows that,adding a balance valve in the hydraulic system can effectively deal with the unstable motion of the spare tire carrier.

关 键 词：备胎架 液压系统 平衡阀 优化改进
