ABSTRACT:
Wheel balancing apparatus includes a shaft for rotating the wheel. Sensing devices are provided on spaced bearings for the shaft to obtain dynamic and positional data concerning the imbalance of the rotating wheel. A feeler arm is mounted so as to be angularly and axially slidably movable about and along an axis parallel to the wheel axis, in such a manner that contact means on the arm are brought successively into contact with opposite edges of the wheel disc. Potentiometers are associated with the arm to sense its axial and angular position when the contact means are in contact with the wheel edges. The radius and thickness of the wheel can then be derived from these positions.
