Wheel Hub Rotary Joint Arrangement

A wheel hub rotary joint assembly with an axis of rotation includes a wheel hub with a wheel flange for connecting a wheel and a sleeve section for receiving a wheel bearing; a constant-velocity rotary joint with an outer joint part, an inner joint part and torque-transmitting elements. The outer joint part has a first spur gearing section with first teeth at its end facing the wheel hub. The sleeve section has a second spur gearing section with second teeth at its end facing the constant-velocity rotary joint. The two spur gearing sections engage with one another for torque transmission. A tensioner for axially tensioning the wheel hub against the outer joint part is axially supported on one side on the wheel hub and on the other side on the outer joint part. At least one of the two spur gearing sections is designed such that, viewed in the radial direction, the first and second teeth initially only come into contact with one another on a small subsurface of the tooth surfaces facing one another during axial tensioning of the arrangement. This subsurface increases in size during further tensioning. The spur gearing sections are designed such that, viewed in the radial direction, the first and second teeth initially come only into contact with one another on the radially inward side during axial tensioning and, as tensioning increases, also come into contact with one another on the radially outward side, for which purpose a substructure of the sleeve section and/or of the outer joint part having the teeth is designed to be more easily deformable in a radially inward region than in a region lying radially further outward.
