ABSTRACT:
A method and apparatus is described for determining the unbalance of wheels mounted on the drive axle of an automobile by transducers detecting the forces and/or vibrations produced by the unbalance present in an automobile wheel which is jacked up for this purpose. Other equipment, in addition to the engine of the automobile, drives or brakes either of the two wheels in order to obtain a speed difference between the wheels. A measuring unit determines the magnitude and direction of unbalance. A device also determines the speeds of the driven wheels.
