WHEEL HUB ROTARY JOINT ARRANGEMENT

摘要

A wheel hub rotary joint assembly includes a wheel hub with a wheel flange and a sleeve section for receiving a wheel bearing; and a constant-velocity rotary joint with an outer joint part having 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 rotary joint. The two spur gearing sections engage one another for torque transmission. 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. Viewed in the radial direction, the first and second teeth initially come only into contact with one another on the radially inward side 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 more easily deformable in a radially inward region than in a region lying radially further outward.
