WHEEL BEARING UNIT FOR A VEHICLE

The disclosure relates to a wheel bearing unit for a drive train of a motor vehicle, having: a wheel bearing hub with a first spur toothing, a joint cap of a drive joint with a second spur toothing, a non-round radially pretensionable element which is accommodated in a recess such that, in an elastically unstressed state, it protrudes at least partially from the recess in a radial direction, and an at least partially conical peripheral surface which, in an at least partially assembled state of the wheel bearing unit, is arranged opposite the radially pretensionable element in the radial direction. The radially pretensionable element and the at least partially conical peripheral surface interact during assembly of the wheel bearing unit in such a way that an axially acting force is generated, which braces the wheel bearing hub and the joint cap against one another.
