商用车V型推力杆失效分析

Failure Analysis of V-type Thrust Bar of Commercial Vehicle

论文以某重型6×4牵引车后悬架V型推力杆橡胶掉落、挤出问题为研究对象,从不同维度对V型推力杆进行排查,确定V型推力杆失效原因,进而制定整改措施,解决了V型推力杆失效问题,经市场用户使用和10 000 km综合道路试验验证,V型推力杆状态良好,未出现橡胶掉落、挤出现象,其改善效果明显,减少了用户抱怨和经济损失。

Taking the rubber falling and extrusion of the V-type thrust bar of the rear suspension of a heavy-duty 6 × 4 tractor as the research object, the failure causes of the V-type thrust bar were determined from different dimensions, and then the rectification measures were formulated to solve the failure problem of the V-type thrust bar. The use of the V-type thrust bar by the market users and the 10000 km comprehensive road test showed that the V-type thrust bar was in good condition without rubber falling and extrusion The results show that the improvement effect is obvious and the user complaints and economic losses are reduced.
