Abstract
A transducer mount for wheel balancing machines of the type having a rotatively driven shaft on which a wheel/tire assembly is mounted. There are two spaced apart bearing blocks that have bearings in which the shaft is supported. The bearing blocks are mounted within a square passageway formed by a rigid structural member. The bearing blocks are dimensioned so that there is a gap between their respective peripheries and the walls forming the passageway. A passive support member extends between the passageway and each of the bearing blocks. An active support also extends between the passageway and each of the bearing blocks, the active spacer including a piezoelectric element which generates a voltage representative of the imbalanced forces in the wheel/tire assembly.
