双横臂独立悬架中断开式转向梯形的优化设计

Optimum Design of Disconnect Type Ackerman Steering in Independent Suspension with Two Transverse Rocker Arms

不等长双横臂独立悬架中断开式转向梯形,是目前国外广泛采用的结构,其整体设计、计算、运动校核及参数间的匹配正确与否,对整车运动的摆振、轮胎磨损有很大的影响。采用优化设计的方法进行设计,其计算实例的精度很高。

Independent suspension with two unequallength transverse rocker arms is a widely utilized structural design overseas nowadays. Reasonable lay-out, calculations, motion checking and matching of various parameters will make the driving of the vehicIe to avoid from shimmy motion and reduce tyre, wear. An optimized design with examples shows that the accuracy of calculation is sufficiently high.
