Abstract: The present invention relates to an assembly which includes: a chassis for a mobile land vehicle, in particular an agricultural or public works vehicle; at least two half-crossmembers (21) mounted telescopically on the chassis; wheel mountings (27) pivotably mounted on each one of said half-crossmembers; steered wheels rotatably mounted on said mountings; and a device for controlling the direction of the wheels. The assembly is characterized in that it includes means (39, 41, 47) designed, for a certain position of two half-crossmembers, to increase, upon the pivoting of the wheels, the opening of the said wheels relative to the opening of the wheels resulting from the same pivoting and another position of the two half-crossmembers.

Abstract: A four-wheel steering system for an automotive vehicle includes a linkage drivingly connected at its front end to a front wheel steering mechanism, and a connecting mechanism assembled in combination with a rear wheel steering mechanism to drivingly connect the linkage to a pair of operation rods of the rear wheel steering mechanism in such a manner that the operation rods are axially displaced in response to movement of the linkage to steer a pair of dirigible rear road wheels. The connecting mechanism is designed to control the steering angle and direction of the rear road wheels relative to those of a pair of dirigible front road wheels without causing any change in the alignment of the rear road wheels.

Abstract: A steering system for a vehicle having a steering wheel and front and rear wheels, including a front steering sub-system for steering the front wheels in accordance with the steering angle of the steering wheel and a rear steering sub-system for steering the rear wheels in the same and opposite directions with respect to the front wheels in accordance with the steering angle of the steering wheel. The steering system is provided with a rack and pinion type variable-ratio mechanism for varying the ratio of the steered angle of at least either of the front or rear wheels to the steering angle of the steering wheel in accordance with the magnitude of the steering angle of the steering wheel. The design freedom in setting a functional relation between the steering angle of the steering wheel and the turning curvature of the vehicle is thus maximized. Moreover, selective setting is permitted for change of ratio of the steered angle of the rear wheels to the steering angle in the vicinity of the initial position of the steering wheel. Further, there is permitted a favorable use of available vehicle dimensions to achieve an optimum feeling characteristic of steering operation.
