ABSTRACT:
An apparatus and method for correcting unbalance of a motor vehicle wheel by at least one balancing weight has a sensor for sensing at least one predetermined position on the wheel, a position detector connected to the sensor for detecting the position thereof, and a storage device connected to the position detector for storing position data determining actual balancing positions on the wheel. An electronic evaluator is connected to a measuring arrangement for measuring wheel unbalance requiring correction and to the storage device for determining the balancing position and the magnitude of the respective balancing weight to be fixed to the wheel. A comparator is connected to the storage device and the position detector. In a retrieval mode, when the sensor reaches a position which corresponds to a stored balancing position a clamping device receives a clamping signal from the comparator for at least partially blocking displacement of the sensor.
