Abstract
A utility vehicle having two steerable front wheels. Left and right-fluid powered rotary actuators have their bodies rigidly attached to the vehicle frame with their drive shafts attached to wheel brackets. The front wheels are each attached to one of the wheel brackets. Each actuator includes a pair of fluid ports, and a piston sleeve which reciprocates within the body of the actuator to rotate the drive shaft relative to the body through a range of at least 180.degree.. Fluid conduit interconnects the ports of the two actuators in series, and with a fluid-control steering valve. Operation of the valve selectively applies pressure to the piston sleeves of the actuators to simultaneously rotate their drive shafts and, thus, the left and right front wheels in unison and in substantially equal angular amounts through a steering range of at least 180.degree.. A motor provides drive to one of the front wheels to facilitate movement of the vehicle forward end when it is not desirable to drive the rear wheels. The rear wheels utilize a second identical steering system.
