Abstract
A balancing machine for vehicle wheels of different sizes and types includes a main shaft, structure for mounting a wheel on the main shaft, and for unbalance measurement which is related to at least one compensating plane of the wheel, sensing structure for detecting a spacing of the at least one compensating plane relative to the machine and for detecting a compensating radius on the wheel. The sensing structure includes a displaceable sensing lever of constant length, the sensing lever having at least a part assuming an angular position proportional to the compensating radius to be detected, a mechanism for pivotally mounting the sensing lever at a first end thereof, structure for displacing the pivotably mounted first end of the lever along a path of given length which is parallel to the main shaft, an element for supplying electrical output signals corresponding to sensed values to an evaluation member in which unbalance measurement values which are ascertained during at least one measuring run are evaluated for determining wheel unbalance and an angle measuring device for measuring an angular position, which is proportional to the compensating radius to be detected, of at least a part of the displaceable sensing lever. The angle measuring device is disposed at the pivot axis of the lever.
