A wheel balancing system for measuring imbalance forces derived from rotating an unbalanced wheel employs a stable pedestal of heavy, rigid material such as concrete or steel and a balancing assembly arranged to insure that all of the imbalance forces of a rotating unbalanced wheel and tire assembly will be directed via strain gauges in predetermined planes. A wheel balancing assembly measures imbalance forces acting in a given plane at a plurality of spaced positions disposed in spaced parallel planes with respect to a plane of rotation of the wheel.

In a wheel balancing machine comprising a rigid base, an elongate rigid bearing housing, bearing means carried within said housing at axially spaced positions, a drive shaft supported for rotation by said bearing means, one end of said shaft being disposed and adapted to readily removably receive a wheel to be balanced, a drive motor carried by said housing and disposed to move therewith independently of said base, means interposed between said housing and said base at first and second axially spaced positions along said housing serving to confine movement of said housing to a plane substantially parallel to said base, said housing, motor and the last named means all lying substantially entirely within the periphery of the tire projected laterally therefrom coaxially of said bearing housing, the last named means being disposed to be subjected to imbalance forces derived from rotation of an unbalanced wheel on said shaft, said forces acting in said plane and in a plurality of spaced parallel planes disposed substantially parallel to and spaced from a plane of rotation of the wheel, and means carried by the second named said means to generate signals proportional to the imbalance forces acting thereon.
