Abstract:
Clamping device for fixing a wheel rim of a vehicle wheel to a shaft of a balancing machine, comprising:a) a locating flange containing a locating face for the wheel rim and which can be fixed to the shaft of the balancing machine, b) a clamping flange arranged on a shaft journal and can be tightened against the locating flange, c) centering bolts concentrically arranged on the clamping flange at uniform circumferential intervals and respectively contain a centering cone that serves for engaging into mounting and centering holes in the wheel rim of the vehicle wheel on their ends that faces the locating flange, d) pins that respectively protrude axially from the centering cone, e) the locating face of the locating flange containing openings, the inside dimension of which openings correspond to the diameter of the pins and the average radial distance of which openings from the rotational axis of the shaft of the balancing machine corresponds substantially to the radial distance of the centering bolts from the rotational axis of the shaft of the balancing machine, and f) the openings are substantially in the form of an annular groove the width of which annular groove corresponds to the diameter of the pins and the average radius of which annular groove corresponds to the radial distance of the centering bolts from the rotational axis of the shaft of the balancing machine.
