Wheel hub rotary joint arrangement
First Claim
1. A wheel hub rotary joint assembly with an axis of rotation, the wheel hub rotary joint assembly comprising:
- (a) a wheel hub with a wheel flange for connecting a wheel, and with a sleeve section for receiving a wheel bearing;
(b) a constant-velocity rotary joint with an outer joint part, an inner joint part and torque-transmitting elements, whereinthe outer joint part has an end face provided with a first spur gearing section with first teeth at an end facing the wheel hub, and the sleeve section has an end face provided with a second spur gearing section with second teeth at an end facing the constant-velocity rotary joint, wherein the first and second spur gearing sections form a gear pair engaging one another for torque transmission;
(c) a clamp that axially clamps the wheel hub against the outer joint part, said clamp being axially supported on one side on the wheel hub and on another side on the outer joint part, whereinat least one of the first and second spur gearing sections is configured such that, viewed in a radial direction, the first and second teeth initially only come in contact with one another on a small subsurface of the tooth surfaces facing one another during axial clamping of the assembly, which subsurface increases in size during further clamping, andeither both end faces of the gear pair formed by the first and second spur gearing sections are curved in a convex manner or only one end face is curved in a convex manner and the other end face is flat, wherein the first and second spur gear sections are each configured such that, viewed in the radial direction, the first and second teeth initially come into load-bearing contact with one another on a radially inward side and, as tension increases, also come into load-bearing contact with one another on a radially outward side, wherein a substructure of the sleeve section and/or of the outer joint part having the teeth is configured to be more easily deformable in a region lying radially further inward than in a region lying radially further outward.

Abstract
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.
