A balancing machine for motor vehicle wheels of different sizes and types has a clamp for clamping wheels on a main shaft of the machine. To measure an unbalance related to one or more compensating planes of the wheel, the machine determines the spacing of the compensating plane (or planes) relative to the machine and ascertains the compensating radius on the wheel. To perform this function, the machine has a sensing member which can be extended in a common plane with the longitudinal center line of the main shaft and which supplies electrical signals to an evaluation device in which unbalance measurement values which are ascertained during one or more measuring runs are evaluated to determine the unbalance of the wheel. The sensing member also has an angle measuring device that measures an angular position of the sensing member (or a part of the sensing member) which is proportional to the compensating radius to be detected.

A balancing machine for vehicle wheels of different sizes and types, said machine comprising: a main shaft, means for mounting a wheel on the main shaft, and for unbalance measurement which is related to at least one compensating plane of the wheel, a sensing means for detecting a spacing of said at least one compensating plane relative to the machine and for detecting a compensating radius on the wheel, wherein the sensing means includes a) a sensing lever telescopically extensible, from a compressed length to an extended length greater than the compressed length, the sensing lever having at least a part assuming an angular position proportional to the compensating radius to be detected; b) means for pivotally mounting the lever at a first end thereof; c) means for supplying electrical output signals corresponding to sensed values to an evaluation means in which unbalance measurement values which are ascertained during at least one measuring run are evaluated for determining wheel unbalance; and d) an angle measuring means for measuring said angular position, which is proportional to said compensating radius to be detected, of at least said part of said sensing lever.
