ABSTRACT:
A digital turn plate apparatus for aligning steering systems of wheeled devices. The turn plate apparatus has a rotational degree of motion for determining the angle of wheel alignment. The turn plate apparatus also has lateral and longitudinal degrees of motion to accommodate the lateral and longitudinal motion of the bottom of tires which can occur during turning or when the suspension is compressed. The turn plate apparatus generally includes a base, a top plate, a handle plate, a lower middle plate, a potentiometer, and a digital display mechanism. The top plate is rotatably mounted to the handle plate and is functionally engaged with the potentiometer. The turn plate apparatus digitally displays the rotational position of the top plate to within a tenth of a degree. The handle plate is constructed to have a longitudinal degree of motion with respect to the base and the lower middle plate is constructed to have a lateral degree of motion with respect to the base.
