A wheel balancer comprises a main housing which supports a sub-housing. A main shaft to which a wheel to be balanced is coupled is rotatable in the sub-housing. The sub-housing is pivotally connected to the main housing by a pivot shaft which defines a horizontal main pivot axis extending transversely of the rotational axis of the main shaft. The sub-housing is pivotal from a horizontal position to a vertical position with the main shaft extending upwardly of the sub-housing to facilitate coupling of the wheel to the main shaft.

Wheel balancer in which a sub-housing carrying a main shaft is pivotal

A wheel balancer comprises apparatus for determining the radius of a rim of a hub of a wheel and for determining the distance of the inner and outer side walls of the hub from a reference plane. A framework which is pivotal downwardly over the wheel to be balanced carries a pair of ultrasonic transducers to determine distance of the sides of the wheel from the reference plane. A transducer monitors the position of the framework. The distances monitored by the ultrasonic transducers are stored in a microprocessor against the corresponding positions of the framework at intervals on movement of the framework. The ultrasonic transducers detect a large change in distance from the reference plane caused by the hub well periphery. The hub rim radius is computed from the well periphery radius, while the distances of the side wall from the reference plane is obtained by looking up the stored values of distances which corresponds with the appropriate position of the framework for the hub rim radius.
