ABSTRACT:
A return device for a hydraulic steering mechanism of a vehicle includes an pparatus for automatically returning the wheels of the vehicle to a straight-ahead position after they are laterally pivoted by a steering wheel acting through a line of shafts. A hairpin spring is stressed by the rotation of a drum mounted on one of the shafts to create a resistance to further lateral pivoting of the vehicle wheels away from a straight-ahead position and a return force to return the vehicle wheels to a straight-ahead position. After the hairpin spring is stressed, a coil spring is tensioned by the rotation of the drum to create an additional resistance to further lateral pivoting of the vehicle wheels away from a straight-ahead position and an additional return force to return the vehicle wheels to a straight-ahead position.
