ABSTRACT:
The invention relates to measuring apparatus and its use, primarily for checking vehicle wheels, and more specifically the alignment of the rotational axes thereof. Two wheels, opposite each other on a vehicle, are provided with projecting stub axles which are disposed accurately coaxial with the respective wheel. The measuring apparatus comprises a scale unit (40) which is mounted on the axle of one of the wheels by means of a locating and fastening means (46, 48) so as to project at right angles therefrom and carrying a movable rider (50) with a scale (55), and a light beam unit (60) preferably comprising a laser (65) and disposed for mounting on the axle of the other wheel, by means of a locating and fastening means (66, 67), to send a light beam (33) onto the scale (55) carried by the movable rider (50) which is locked in an initial position. The measurements are carried out by the units (40, 60) being swung around the centers of the stub axles to different positions and possible movements of the point of incidence of the beam (33) on the scale (55) are observed.
