Abstract
The invention relates to a face spline of a toothed rim running in the circumferential direction around a rotation axis on a wheel-bearing arrangement for a driven wheel hub. The face spline is provided for play-free engagement with the counter-spline, facing the face spline and the teeth of the face spline have a wedge-like embodiment such that the geometrical lines of the face spline meet centrally at a common point on the rotation axis and the teeth thus run in the radial direction on the rotation axis.
Claims9
A face spline comprising a toothed rim which extends about a rotational axis in the circumferential direction on a wheel bearing arrangement for a driven wheel hub, the face spline being provided for playfree engagement into the mating spline which faces the face spline, and the teeth of the face spline being of wedge-shaped configuration in such a way that the geometric lines of the face spline meet centrally at a common point on the rotational axis and the teeth therefore extend in the radial direction toward the rotational axis wherein the flanks of the teeth of the face spline which are provided for the engagement are inclined at a flank angle (α) greater than 20° and smaller than 30° with respect to an imaginary pitch plane which leads away from the rotational axis and in the process divides the respective tooth symmetrically.
