Abstract
An apparatus for determining the unbalance of wheels mounted on a vehicle comprises at least one measuring rack for supporting a vehicle wheel, a sensor provided in the measuring rack for sensing vibrations caused by the unbalance and for issuing a sensor signal. A measurement/control unit generates unbalance signals from the source signals which represent the unbalance with respect to magnitude and direction. At least the unbalance magnitude is displayed at a display unit. A wireless signal transmission unit is disposed in the path between the sensor and the display unit. A central display and control unit is provided for several measuring racks, the measuring racks and the display control unit comprising a transmitter/receiver for signal transmission. Thus signals are transmitted from the measuring racks to the display control unit and control signals are transmitted from the display control unit to the measuring racks.
