ABSTRACT:
A dual shaft rack and pinion steering assembly for a vehicle includes a housing mounted to the vehicle and containing first and second parallel shafts linked to one another for synchronized axial movement. The first and second shafts are slidably positioned within the housing. One of the shafts includes a piston operable by hydraulic fluid contained within the housing. The other of the shafts includes a rack of teeth for meshing with a pinion gear driven by a steering column. The hydraulic fluid operates the piston by pressure coordinated with the driving of the rack by the pinion gear to assist the coordinated movement of the dual shaft assembly. The linked parallel shafts are connected to a drag link to direct a first wheel in response to axial movement of the shafts, which is further connected to a cross car link simultaneously directing a second wheel.
