A steering system for motor vehicles including agricultural machines is provided. The system includes a first conventional steering assembly for the front wheels to rotate only each of the front wheels within a respective first predetermined steering angle, each front wheel rotatable to a pre-determined first maximum value within its pre-determined angle. The system also includes a second steering assembly to independently steer a front axle and the front wheels within a second pre-determined steering angle. The second steering assembly is activated only after each of the front wheels have reached its respective first maximum value within its first pre-determined steering angle, during the conventional steering performed by the first conventional steering assembly.

Steering system for motor vehicles, in particular for agricultural machines

A hydraulic valve having a main body in which is formed a pressurized-fluid inlet opening; a first conduit communicating hydraulically with a user device; a second conduit communicating hydraulically with the user device, and at least one spool for regulating pressurized fluid flow to and from the user device; the spool having a longitudinal axis, and the position of the spool being regulated by an actuating device; the hydraulic valve being characterized in that the actuating device has a guide member for preventing the spool from rotating about the axis; the actuating device also having a cable, e.g. a Bowden-type cable, for moving the spool in two opposite directions defined by the longitudinal axis.
