A vehicle wheel and tire balance testing machine arranged with an unbalance sensitive member arranged along side the wheel and tire assembly, means to support the unbalance sensitive member so any unbalance forces generated upon rotation of the wheel and tire assembly will be picked up in the sensitive member, force transducer means engaged against the sensitive member in positions spaced from the wheel and tire so as to generate signals proportional to any unbalance present in the wheel and tire, means associated with the force transducer means for resolving the signals into the amount of unbalance in two planes of the wheel and tire assembly, and means for monitoring the location of the unbalance about the circumference of the wheel and tire in the respective planes thereof where unbalance is found.

In a balance testing machine for vehicle wheel and tire assemblies having inside and outside reference planes representing the thickness of the assembly as measured along the axis of rotation, the combination comprising: a frame; a drive shaft in said frame; an unbalance force sensitive member in said frame; a drive motor connected to said drive shaft; a driven shaft carried by said force sensitive member and flexibly connected to said drive shaft; a plurality of flexible means supporting said force sensitive member in operative position in said frame to permit said force sensitive member to react in response to unbalance forces substantially only on one plane, said flexible means being directed at substantially right angles to said force sensitive member; a wheel and tire assembly rotatively carried by said driven shaft in position to have its inside reference plane spaced from and substantially parallel with a portion of said force sensitive member a distance less than its outside reference plane; force transducer means operatively disposed under preload between said frame and a portion of said force sensitive member for substantially rigidly engaging the same and being positioned outside of alignment with and spaced from the inside and outside reference planes a fixed distance; means connected to said force transducer means for converting the unbalance force sensed thereby into terms of counter balancing weight; and monitoring means responsive to rotation of said wheel and tire and adapted to locate the angular position of unbalance about the circumference of the wheel and tire.
