Abstract
A wheel alignment apparatus and method are provided for use in aligning the front wheels of a vehicle. The wheel alignment apparatus includes a dynamic wheel aligner which determines the dynamic toe angle and dynamic camber angle of a wheel using the axial displacement of rolls upon which each front wheel is rotatable. The wheel alignment apparatus stores these dynamically determined values and stops the rotation of the rolls. After predetermined time delays, an alignment operator makes adjustments to the toe and camber angles of the wheel so that these angles are within a desired range. The changes in the toe angle and camber angle during alignment are determined by the apparatus and combined with the dynamically determined toe and camber angles. As a result, the alignment operator continuously has a visual indication of the toe and camber angles during alignment. The wheel alignment apparatus also removes unwanted changes in the tow angle which occur during the predetermined time delays so that the visual indication accurately reflects the dynamic toe angle.
