摘要： The present invention relates to a steering system and an independent suspension wheel-type heavy vehicle. The steering system comprises a steering mechanism for providing a steering force to wheels and a steering hydraulic assisting system for providing a steering assisting force overcoming a steering resistance moment from the ground to the wheels. According to the invention, by providing the steering mechanism for providing a steering force to wheels and by providing the steering hydraulic assisting system for providing a steering assisting force overcoming a steering resistance moment from the ground to the wheels, the steering resistance moment from the ground can be effectively overcome, and the vehicle is offered the steering capability for various places, as compared with a steering system only depending on the torque output by a steering gear or only depending on the torque output by the steering gear and a steering assisting follower.

摘要： The present application discloses a steering control system, a method and a crane. The steering control system includes: one or more first angle sensors, one or more second angle sensors, and a steering controller; each of the first angle sensors collects an actual steering angle of a wheel corresponding to a mechanical steering axle as a first steering angle; each of the second angle sensors an actual steering angle of a wheel corresponding to an electrically controlled steering axle as a second steering angle; the steering controller obtains a theoretical steering angle of the wheel corresponding to the electrically controlled steering axle in a corresponding travel mode according to the first steering angle, and compares the second steering angle with the theoretical steering angle, to control the wheel corresponding to the electrically controlled steering axle to steer according to a difference therebetween.
