清障拖车总体设计

Complete Design of Towing Vehicle

将4×2重卡底盘改制成额定托举质量为7t的清障拖车,介绍了底盘的改制方法、总布置和工作结构计算,并在配重合理布置的基础上完成了建模设计,通过CAE强度分析,校核了前后桥的轴荷分配,证明了改制方案能够满足整车性能要求。

The heavy duly truck 4 × 2 chassis was integrated for being reformed to be towing vehicle which met the rated lifting quality of 7T and should guarantee the distribution of front and rear axle loading to be reasonable for meeting the requirement of vehicle performance. The mode designing was done based on showing the lifting requirement, introducing the method of reforming chassis, general arrangement and calculating the working structure, assembly reasonable. The CAE strength analysis was done and then the wrecker was successful of trail.
