<p>A centering compensator (212) for resisting movement of the steerable wheels of a vehicle either side of a selected center position, and for returning them to this center position after each such movement. The apparatus includes a cam follower member (46) connected to the steerable wheels for movement therewith and arranged to engage the cam surface of a cam ring (52') having one or more static rotational positions relative to its housing mounted on the vehicle frame. The cam surface has a centering depression and the follower member is carried by an arm member extending laterally from a centering shaft (15) mounted for rotational movement relative to the cam ring. An actuator assembly (214, 216) applies a resilient biasing force to the follower arm for pressing the follower member into the centering depression in response to fluid pressure in a piston and cylinder assembly (80', 82'). The center position may be varied either locally or remotely by changing the static rotational position of the cam ring or the length of a centering shaft linkage.</p> |
