<p>An apparatus for balancing a body such as a motor vehicle wheel in two balancing planes whereby a driving shaft is supported by two separated bearings, one movable and the other immovable and, each having a force measuring device associated with it for each measuring the force which the shaft applies to its associated bearing. The force measuring devices are connected via suitable resistances to a two position switch which in turn is connected to an indicator for displaying imbalance. The switch has a first position connecting both force measuring devices to the indicator so that, when the body is mounted with one of the planes coinciding with the immovable bearing, the indicator displays the imbalance in that plane after imbalance in the other plane has been corrected. The second switch position connects only the force measuring device associated with the movable bearing to the indicator so that, when the body is mounted with the one of the planes coinciding with the immovable bearing, the indicator displays the imbalance in that other plane.</p> |
