轮式工程车辆的转向系统要求能够灵活地转向行驶，应避免轮子的滑移或侧滑。常见的工程车辆有两种转向方式，通过对两种转向运动形式进行详细的运动和动力学分析，提出它们的使用范围，并对这两种转向方式的轮式车辆提出应该重视的技术问题及措施。

The steering systems of wheeled project vehicles are required to be steered smoothly and free of wheel slide and wheel sideslip. The wheeled project vehicles usually have two types of steering systems, i.e., deflectionwheel steering system and integralcarriage steering system. In the paper, detailed kinematics and kinetics analysis is made for the two types of steering system, the application scopes of the two steering systems are provided and some technical countermeasures for the wheeled project vehicles with the two types of steering systems are recommended.
