A steering apparatus (10) responsive to rotation of a handwheel (40) for turning steerable wheels (14, 16) includes a first steering gear (22) actuatable to affect turning of a first set (14) of steerable wheels (14a, 14b) and a second steering gear (24) actuatable to affect turning of a second set (16) of steerable wheels (16a, 16b). A torque transmission device (70) includes an input member (72) connected to the handwheel (40). A first output member (82) is mechanically coupled to the input member (72) and connected to the first steering gear (22) for actuating the first steering gear (22). A second output member (92) is mechanically coupled to the input member (72) and connected to the second steering gear (24) for actuating the second steering gear (24). A sensor (58) senses at least one condition of the handwheel (40) and provides a steering signal to a controller (62) that receives the steering signal and controls rotation of the input member (72) of the torque transmission device (70) for controlling actuation of the first and second steering gears (22, 24). |
