Abstract:
In a wheel balancer comprising:a shaft adapted for receiving a wheel/tire assembly, said shaft having a longitudinal axis and being rotatable about said axis so as to rotate the wheel/tire assembly removably mounted thereon; a rotation sensor assembly for measuring rotation of the shaft about the longitudinal axis of the shaft; a vibration sensor assembly operatively connected to the shaft for measuring vibrations resulting from imbalance in the wheel/tire assembly; a motor operatively connected to the shaft for rotating said shaft about said longitudinal axis, thereby to rotate the wheel/tire assembly; a load roller for applying force to the wheel/tire assembly during rotation thereof; and a control circuit for controlling the force applied by the load roller to the wheel/tire assembly during rotation, said control circuit causing the load roller to vary the force applied by the load roller to the wheel/tire assembly.
