Patent ID: 8444322

Claim:
A face spline, comprising: a toothed rim which has a plurality of teeth and which extends about a rotational axis in a circumferential direction on a wheel bearing arrangement for a driven wheel hub, the face spline engaging without play into a mating spline which opposes the face spline, and the teeth of the face spline being of wedge-shaped configuration and being described on a tip, a root and a flank side by radially oriented geometric lines of the face spline, the geometric lines meet centrally at a common point on the rotational axis and the teeth therefore extend in a radial direction toward the rotational axis, wherein flanks of the teeth of the face spline, which are provided for the engagement, are inclined at a flank angle greater than 20° and less than 30° with respect to a pitch plane which leads away from the rotational axis and divides each tooth symmetrically, wherein tooth gaps of the face spline are rounded concavely with at least one root radius between two adjacent flanks, wherein the tip of each tooth is rounded with at least one convex tip radius at least from one flank to another flank of each tooth, the tip radius being greater than the root radius, wherein a quotient from a greatest theoretical tooth height of each tooth and the tip radius corresponds at least to five and at most to nine, the greatest theoretical tooth height in the pitch plane being a greatest axial spacing between a first cut edge and a second cut edge, and two geometric planes which face one another intersect in the first cut edge and the second cut edge, and each of the geometric planes delimiting one of the flanks geometrically, the geometric planes of the flanks of each tooth intersecting in the first cut edge at a tip side of the tooth, and the geometric planes of two flanks, which lie opposite one another at one tooth gap, of mutually adjacent teeth intersecting in the second cut edge at a root side of the tooth.
