后轮转向机构与悬架的协调作用可以减小轮胎的磨损、改善转向轻便性、提高整车稳定性。针对一种新的后轮转向机构，运用空间解析法对车轮跳动时后轮转向拉杆与钢板弹簧的不协调运动偏差的目标函数进行了优化设计，并在Adams／Car中建立了后轮转向机构和整车的虚拟仿真模型。仿真结果和试验数据表明，经过优化后，后轮转向机构的轻便性有所提高，整车的操纵稳定性有所改善。

Coordinating role of the rear wheel steering and suspension can reduce tire wear, perfect the steering portability, and improve the stability of the vehicle.A new rear steering mechanism was proposed;and the objective function of uncoordinat-ed movement deviation between the rear wheel steering drag link with steel plate spring was designed and optimized by using spa-tial analytic method.And the virtual simulation model of rear wheel steering mechanism was established in the Adams/Car.Re-sults show that the function of rear wheel steering can improve the vehicle's handling stability and perfect the steering portability after optimization design.
