ABSTRACT:
A dynamic vehicle wheel and tire balancing system with manual rotation of the shaft to which the wheel and tire is attached. A computer within the system receives entered premeasured values of wheel dimensions and are in response to the output of a rotational speed sensor determines a proper rotational speed of the shaft at which point it automatically decouples the manually operated crank from the wheel shaft so that there can be no externally applied disturbances for the subsequent measurements of imbalance. Twin spaced transducers along the shaft determine the wheel runout attributable to imbalances in both inner and outerwheel rims and the computer provides output signals indicative of the correct balance weight and the mounting positions of the weights on the wheel rim.
