ABSTRACT:
An arrangement for the measuring and correction of the steering geometry of motor vehicles, in particular their alignment and camber angles, through the intermediary of mechanical components associated with each wheel of a wheel pair and which serves for the scanning of the actual value of the wheel angles, whereby the values determined in this manner are converted into electrical signals through the utilization of data pick-ups and are then displayed. This arrangement essentially inventively consists of in that in the measuring of the steering geometry provided as the measuring basis on the wheel suspension of a wheel pair with the utilization, for instance, of individually adjustable wheel positioning elements, of which each is connected with a carriage extending transverse of the travelling direction of the wheels and supporting the actual value scanning elements, and in which one of the two wheel positioning elements has associated therewith a longitudinal measuring system serving for the correction of the alignment angle (.alpha.), during the displacement of which there is produced a correction angle (.alpha..sub.k) in a calculator connected to the output thereof, and in conjunction with the actual value wheel angle (.alpha.) separately obtained for each wheel of the wheel pairs superimposes itself in the counters associated with the calculator as well as with the measured value pick-ups associated with the inherent wheels, and which are displayed as a real correcting magnitude, whereas the actual value wheel angle (.beta.) of each wheel is conveyed directly to the counters.
