A method and an arrangement for releasably clamping a motor vehicle wheel to a shaft of a balancing machine, in which when clamping the wheel on the shaft a clamping nut is held fast and the shaft is driven in rotation by the drive motor of the machine. The nut is thereby tightened on the main shaft to clamp the wheel in position thereon. The nut can be released by reversing the procedure.

Method and arrangement for clamping a motor vehicle wheel on a balancing

A clamping arrangement for clamping a rotary member to be balanced on a main shaft of a balancing machine comprises a centering cone which is axially resiliently supported on the shaft for centering the rotary member with respect to the shaft. A pressure element can be fixed on the shaft for pressing the rotary member against the centering cone into a centering position, and a support flange holds the rotary member against the pressure element. The support flange is non-rotatably and axially displaceably mounted on the shaft and can be pressed by an actuating means against the rotary member which is held in a centered condition, whereby the rotary member is clamped against the pressure element on the shaft.
