摘要： A motor vehicle has two steerable righthand and lefthand front wheels and two steerable righthand and lefthand rear wheels, a front wheel steering device for steering the front wheels according to the angle through which a steering wheel is turned, a rear wheel steering device for steering the rear wheels, an actuator for actuating said rear wheel steering device, and a control device for controlling the operation of the actuator to steer the rear wheels in a direction which is selectively the same as or opposite to the direction in which the front wheels are turned. The steering of the rear wheels is controlled by determining the speeds of rotation of the four front and rear wheels with respect to the ground, and controlling the operation of the actuator with the control device so that any difference between the speeds of rotation of the front and rear wheels with respect to the ground will be reduced substantially to zero.

摘要： A steering system for vehicles in which the steered angle ratio of a rear wheel to a front wheel is controllable in accordance with the vehicle speed. The steering system is provided with a manual switch device for selecting to set an arbitrary one of a plurality of predetermined steered angle ratios. The steering system may be further provided with a switch lock device for locking the switch state of the manual switch device. The switch lock device may be actuated when the vehicle speed is higher than a predetermined reference vehicle speed. Further, the switch lock device may be actuated when a reduction gear is shifted to a shift position having a relatively low reduction ratio. The switch lock device may also be actuated when the steered angle of the front wheel is larger than a predetermined value.

摘要： A steering apparatus for a four-wheeled vehicle including a pair of pivotable knuckle arms connected to a pair of respective front wheels and actuatable through a steering gear by rotational movement of a steering wheel. One of the knuckle arms is pivotally connected to one end of a connector rod extending longitudinally of the vehicle, the other end of the connector rod being connected to a cam plate slidable in a housing. The cam plate has an inverted S-shaped cam groove or alternatively an S-shaped cam groove within which is slidably received a pin mounted on a tie rod pivotally connected between a pair of pivotable support arms supporting a pair of rear wheels, respectively. Due to the shape of the cam groove, the rear wheels are turned in the same direction as the front wheels when the steering wheel is rotated through a relatively small angle, and the rear and front wheels are turned in opposite directions when the steering wheel is rotated through a relatively large angle.
