Improvement to steering systems

摘要

These improvements relate to steering systems for mainly agricultural machines having two guiding axles - front and rear - and the wheels of which are steered, in bends, respectively in opposite directions in order to reduce the turning radius and so that the rear wheels pass along the path of the front wheels in order to reduce the damage to the crops when this machine is a spraying machine. When the front wheels are turned through an angle greater than a given value C0, and with a certain offset - D - connected with the machine - the rear wheels are turned by the same amount but in the opposite direction from the front wheels. Upon coming out of the bend, the straightening-up command is given from an angle C1 and with a certain similar offset E. <IMAGE>
