从减小冲击车辆的角度,初步分析了当负重轮以较高速度抬升时车辆对减振器阻尼特性的总体要求。根据液力式和摩擦式2种减振器的阻尼特性,针对2种车型的减振器联动杠杆机构,用图解法分别分析了负重轮在相同摆动速度和相同受力条件下,经联动杠杆作用后减振器摆臂运动速度和受力的变化趋势,并据此对这2种车型和2种形式的减振器阻尼与车体阻尼需求的匹配情况进行了评述。结果表明:联动杠杆对减振器性能的发挥存在影响,所分析的2种车型的杆系和使用的减振器性能配合不够理想。
From the point of view of reducing the impact of the vehicle, the general requirements of the vehicle on the damping characteristics of the shock absorber are analyzed preliminarily when the road wheel is lifted at higher speed. According to the damping characteristics of the two types of shock absorbers, the paper analyzes the shock absorber linkage lever mechanism of the two kinds of models by the graphic method and analyzes the influence of the load wheel under the same swinging speed and the same force by the linkage lever After the action, the changing trend of the speed and force of the arm of the shock absorber is analyzed. Based on the above, the matching between the damping of these two kinds of vehicles and the damp damping of the two kinds of vehicles is commented. The results show that the linkage lever has an impact on the performance of the shock absorber, and the performance of the two systems of the two models and the shock absorber used are not satisfactory.
