摘　　要：液力缓速器作为重要的车辆辅助制动装置,其对整车制动稳定性具有较大影响。根据液力缓速器的结构特点和工作原理,制定液力缓速器对整车制动稳定性影响评价指标,选取理想制动力分配曲线(I曲线)和加装缓速器之后实际制动力分配曲线(β曲线)作为定性分析指标,分析液力缓速器对整车制动性能的影响。通过分析可知,通过调节液力缓速器制动力矩可以达到车辆制动中β曲线逼近I曲线,更充分利用液力缓速器的缓速制动力矩,降低行车制动的负担,且尽量降低缓速器的使用对行车制动稳定性的影响。对整车制动性能影响的研究可以为产品设计提供参考,研究内容和研究成果可以作为此类设计研究的参考依据。Hydraulic retarder as an important vehicle auxiliary braking device,has a greater impact on vehicle braking stability. According to the structural characteristics and working principle of the hydraulic retarder,it chooses ideal brake force distribution curve （I curve）and actual braking force distribution curve under installation the hydraulic retarder （fl curve）as effect assessment index. It analyzes the effect of hydraulic retarder on the vehicle braking stability. Through analysis ,by adjusting the hydraulic retarder braking torque it can achieve vehicle braking curve β curve approximating I curve to more fully utilize hydraulic retarder braking torque ,and reduce the burden on service brakes ,and reduce the effect of the use of hydraulic retarder on brake stability. Vehicle braking performauce impact on the research can provide a reference for product design,research and research results can be used as reference for this type of study design.
