A light projector mounted on a front wheel of a vehicle uses a single laser to develop a beam which is split into a pair of light beams. The first light beam is projected to a calibrated mirror mounted on an adjacent rear wheel and is reflected to a target mounted near the projector on the front wheel of the vehicle so that the front wheel may be aligned with the rear wheel. The second light beam is projected to a mirror mounted on the other front wheel and is reflected to a target mounted adjacent the projector to check the toe of the front wheels. The ...
Apparatus for measuring wheel alignment of a motor vehicle comprising: means for projecting a directional beam of light; means for attaching said projecting means to a first wheel of said vehicle for projecting said directional beam with the longitudinal axis of said beam being in a predetermined angular relationship to a line generally parallel to the axis of rotation of said first wheel; a multichannel photosensitive encoder positioned to intercept said beam, said encoder having means for generating a plurality of binary signals indicative of the dista...
