Wheel bearing unit for a vehicle

A wheel bearing unit for a drive train of a vehicle comprising:

• a wheel bearing hub with a first spur toothing,
• a constant velocity joint of a drive joint with a second spur toothing,
• a radially pretensionable element that is accommodated in a recess in such a way that, in an elastically unstressed state, it protrudes at least partially from the recess in a radial direction (R), and
• a 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 (R),
• wherein the radially pretensionable element and the 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 constant velocity joint against one another.
