ABSTRACT:
The invention relates to a method and apparatus for dynamically measuring vehicle front end parameters such as toe-in (or toe-out) and camber angle. The apparatus includes a separate pair of support rollers for supporting each vehicle front wheel and causing rotation thereof. A sensing roller is adapted to contact the tire tread surface at the lowermost point of the tire so as to be rotated by rotation of the wheel. The axis of the sensing roller is arranged transverse to the plane of rotation of the wheel such that any toe-in or toe-out of the wheel causes a transverse or generally axial displacement of the sensing roller to a position wherein the axis of the sensing roller is normal to the toe-in or toe-out direction of the wheel. The sensing roller is mounted on an axle which forms one bar of a trapezium shaped four bar linkage which causes said sensing roller to pivot about an effective pivot point which is arranged, by means of said linkage, a considerable distance away from the wheel. The pivot point is the point of intersection of the center lines of the tapered sides of the linkage since the bars of the linkage are pivotally interconnected. A further sensing roller for measuring camber angle and methods of measuring toe-in and camber angle are also disclosed and claimed.
