ABSTRACT:
A shaft angle sensing arrangement for an implement steerable axle includes a shaft rotatable about a shaft axis within shaft mounting structure, a cam ring with a cam surface mounted over the shaft, and a threaded aperture in the axle housing adjacent the cam surface. As the cam ring rotates with the shaft, the distance between the cam surface and the support area varies. A displacement transducer threaded into the aperture includes a contact member engaging the cam surface so that rotation of the shaft causes the contact member to move dependent on the angular position of the shaft to provide a shaft position feedback signal to an automatic position controller or readout device.
