For a dynamic balancing machine the values of parameters employed to determine the weight, rim spacing and diameter of a wheel are automatically entered into the balancing machine by a single maneuver of an extensible wand. This simplicity eliminates many opportunities for human error when obtaining the same information otherwise.

Data input system for dynamic balancing machine

An improved wheel balancing system employs an information entry system with selectable compensation for input of information so that the balancing procedure can be standardized notwithstanding the fact that different styles of wheels are to be balanced. Means making the selection of compensation includes manually or electrically operated means. In one embodiment the selectively operable compensation means responds to an output from the wheel balancing machine. A zero value is displayed for calculated weights below a predetermined minimum in response to the output from the balancing machine.

Wheel balancing system

An information sensing system as used in sensing unbalanced forces acting upon a rotating wheel being balanced is characterized by means for generating a correction factor associated with each wheel balancing operation and determined by feeding a known signal through a given circuit and comparing the output received with the output expected. The correction factor can then be applied to the sensed signals fed through the same circuit. The frequency of the known signal and other signals are both derived from the same source such as the rate of rotation of the wheel.
