Patent ID: 7380334

Claim:
A device for prestressing a wheel bearing, comprising an arbor rotating at least at times about a rotational axis of the wheel bearing with respect to a clamping mechanism, wherein the clamping mechanism prestresses the wheel bearing in the device and wherein the arbor sets into rotational motion about the rotational axis of the wheel bearing a flange rotatably supported in an outer ring of the wheel bearing, at least at those times when the wheel bearing is prestressed in the device, wherein the clamping mechanism is disposed rotationally fixed with respect to the device and for prestressing the wheel bearing in the device is movable from outside radially in the direction of the rotational axis against the outer ring, the clamping mechanism is adaptive to outer rings differing from one another in their outer diameter by means of at least one thin-walled as well as elastically deformable intermediate ring developed as a hollow cylinder, radially between the clamping mechanism and the outer ring.
