Abstract
A wheel balancer is provided that includes a shaft adapted for receiving a wheel/tire assembly, the shaft having a longitudinal axis and being rotatable about the axis so as to rotate a wheel/tire assembly removably mounted thereon, a rotation sensor assembly for measuring rotation of the shaft about its longitudinal axis, a vibration sensor assembly operatively connected to the shaft for measuring vibration resulting from imbalance in the wheel/tire assembly, a motor operably connected to the shaft for rotating the shaft about its longitudinal axis, a load roller for applying force to the wheel/tire assembly during rotation thereof. A control circuit is also included for controlling the force applied by the load roller to the wheel/tire assembly during rotation. The control circuit causes the load roller to vary the force applied by the load roller to the wheel/tire assembly.
