Abstract: A steering mechanism of a vehicle including a front wheel steering mechanism for steering front wheels of the vehicle, a steering wheel wheel for effecting a steering movement of the front wheel steering mechanism to a desired angle, a rear wheel steering mechanism for steering rear wheels of the vehicle, a control unit for effecting a steering movement of the rear wheel steering mechanism in relation with the steering movement of the front wheels. The arrangement is such that a ratio of the steering angle of the rear wheel to the steering angle of the front wheel is increased in the same direction of steering as the steered direction of the front wheels as the rate of the steering operation for the steering wheel is increased so as to obtain a desirable steering movement of the rear wheels.
Abstract: The invention relates to an axle suspension means for motor vehicles, wherein the guide means of a rigid axle is constructed so that the latter changes its position in the sense of a positive oblique springing during inward spring stroke movements, and executes no inherent steering movements during one-sided and alternate-side inward and outward spring strokes. For this purpose the rigid axle is guided on each side by a pair of guiding control arms which determine, for its wheel axis, a pivot axis about which the wheel axis is movable by means of a guide arm retained on the vehicle body in the sense of the positive oblique springing during inward spring stroke movements.
