某重型自卸车前桥转向梯形及运动干涉分析

A heavy dump truck front axle and steering trapezoid motion interference analysis

根据总布置要求,某重型车(6×4自卸车)需要加装大轮胎12.00R24,中后桥轴距增大,需要重新分析前桥梯形在新的轴距下是否满足要求;同时由于换装大轮胎需要重新设计直拉杆结构,从而需要重新校核直拉杆在转向过程中是否会与其他零部件存在干涉现象。

To satisfy the request of general layout ,Y30F0 should install big tyre 12.00R24, the wheel base of middle and rear axle increase, then we should analyse that the front axle trapeze whether satisfy the demand under the new wheel base; Also the straight pull rod should be designed because of installing big tyre, as a result we should verify that the straight pull rod whether has interference phenomena with other parts during turning course.
