为了解决翻转机构在不同车型驾驶室上较难翻准的问题,通过对翻转机构局部结构进行优化设计以及采用对比分析的方法,得出优化后的翻转机构可以根据不同车型驾驶室调整扭杆预扭角的大小,分析结果表明优化后的翻转机构相较于优化前操作力明显减小,且能调整到一个最合理的状态使得驾驶室翻转更轻便。优化后的翻转机构在不同车型驾驶室上均可以轻易实现翻转过程,问题得到了解决。 In order to solve the problem that the turning mechanism is difficult to turn over on the cab of different models, through the optimization design of the local structure of the turning mechanism and the method of comparative analysis, it is concluded that the optimized turning mechanism can be adjusted according to the cab of different models The result of the analysis shows that the optimized turnover mechanism is significantly reduced compared with that before optimization and can be adjusted to the most reasonable condition to make the cab flip more lightweight. Optimized flip mechanism in different models of the cab can be easily achieved flip process, the problem has been solved.
