The invention relates to a spur toothing on at least one coupling element for transmitting torques about a rotational axis, said spur toothing axially engaging with a corresponding mating cutting. The face cutting is provided with teeth from a material of the coupling element that has been plastically shaped in an at least partially noncutting manner.

Spur toothing on a coupling element for transmitting torques

The invention relates to a spur toothing on at least one coupling element for transmitting torques about a rotational axis, said spur toothing axially engaging with a corresponding mating cutting. The face cutting is provided with teeth from a material of the coupling element that has been plastically shaped in an at least partially non-cutting manner.

A face spline of a toothed rim running in a 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.

Face spline for a driven wheel hub

A hub on a wheel bearing unit, which has at least one inner ring, sitting on the hub. The inner ring is axially retained on the hub by a collar, which has a toothing, formed from the hub. The inner ring has a radially inward broken-out section on the front face thereof and the broken-out section is filled with plastically displaced material from the collar such that the material of the inner ring at least engages in the broken-out section and the material in the broken-out section is enclosed in the radial direction by the inner ring.

Hub for a wheel bearing unit

The invention relates to a securing device for a bearing ring in a housing. At least one spring element engages in an annular groove of the housing and at least one angled collar supports the bearing ring in an axial manner. The spring element is hook-shaped and forms an angle that extends in a radial manner towards the outside and at least partially back in the axial direction. At least one push element is formed on the securing device, which is actively connected to the spring element in such a manner that the spring element is prestressed in an axial manner, by actuating the push element.

Securing device for a bearing ring in a housing

A collar, made from plastically deformed material, of a hub. The collar holds at least one inner ring of a wheel bearing unit on the hub in an axially fixed manner. Also, end-side teeth, are formed in the collar for engaging in a mating toothing.

Collar having end-side teeth for a drivable wheel hub

The wheel bearing joint unit having an inner ring that sits on a hub of the wheel bearing joint unit. The inner ring is axially retained on the hub using a collar that is formed from the hub. The collar is provided with a toothing which meshes with a corresponding opposite toothing on a joint part. The toothing and the opposite toothing are braced against each other by a screw which rests on the hub and engages into a thread on the joint part. The joint has two axial projections, one which has the toothing to engage the toothing on the collar and another with the threading to engage the screw. These two projections are spaced apart by a groove to provide flexibility.
