中文摘要: |
通过扭杆来进行车高调节的非承载式(带车架)车型,使用常规的工艺方法——整车下线通过颠簸路消除残余应力,在四轮定位之前设置地沟进行车高调整,由于悬架残余应力释放不彻底,在经过动态路试后,出现车高发生明显变化的现象,而且地沟调节车高工序时间较长,成为节拍提升的瓶颈。为了解决上述问题,介绍一种车高调整优化工艺方法,整车下线采用一台设备来充分释放悬架残余应力,车高调整工序分解为第一步的车架线初调和第二步的地沟微调。实施优化后的工艺方法,显著缩短了地沟车高调整时间,而且很好地控制了动态路试后车高的稳定性。 |
英文摘要: |
To non bearing type(with frame) model which vehicle height is adjusted through torsion bar, using conventional methods——at the end of the assembly line, residual stress is eliminated through a bumpy road, before the four wheel alignment, a trench is set to adjust vehicle height. Owing to the release of the suspension residual stress is not complete, after a dynamic road test, the phenomenon that vehicle height changes obviously arises. Meanwhile longer process time of adjusting vehicle height in a trench becomes the bottleneck. In order to solve the above problem, an optimized process method of vehicle height adjustment was introduced, an equipment was used to fully release residual stress of the suspension at the assembly line’〖KG-*2〗s end, and the vehicle height adjustment process was decomposed into the first step initial adjustment in the frame line, and the second step fine tuning in the trench. Through implementing the optimized process, the vehicle height adjusting time in the trench is shorten significantly, and the vehicle height stability after dynamic test drive is controlled well. |
