The present invention relates to a measurement system for measuring wheel angles and determining the position of chassis units on a vehicle. The measurement system includes a measuring unit which can be mounted on a vehicle and arranged to measure angles and distances in the horizontal plane with reference to the longitudinal axis of the vehicle, and in the vertical plane with reference to the vertical direction. The results of measurement are fed to a control unit, connected to the measuring unit by a lead. A computer which compiles and computes the mea...
[ We claim:] [1.] Apparatus for measuring wheel alignment angles of a wheeled vehicle in relation to the longitudinal axis of such vehicle, said apparatus comprising at least one measuring unit for mounting to the outside of a vehicle wheel, said measuring unit including a radiation source for emitting a thin, parallel beam towards a target mounted adjacent a respective end of said vehicle, said target having a plurality of sensitized marks, a drive device for imparting to the beam a rotary, sweeping movement in the horizontal plane, an angle measuring d...
