A method and apparatus for measuring the alignment of vehicle wheels includes a light source having two beams projecting on opposite directions. The source is mounted on the wheel approximately perpendicular to the wheel axis. Measuring scales are mounted along the paths of the beams in front of and behind the wheels. When taking measurements, the wheel is rotated 180°after a first measurement and a second reading of the scales is made. The difference between the two sets of readings is used to determine the deviation of the light beam from the perpendic...
A method for the measuring and adjustment of a wheel on a vehicle comprising the steps of placing the vehicle on rollers, mounting on the wheel light beam projection means emitting light beams in opposite directions and approximately perpendicular to the axis of rotation of the wheel, placing cooperating scales at different locations lengthwise of the vehicle and in the projection paths of the light beams, activating the light beam projection means and rotating the wheel on the rollers so that the opposing beams each give a reading on the corresponding c...
