Abstract

Official abstract text for this publication.

A seal arrangement for a wheel bearing arrangement of a motor vehicle, including a seal body having a sealing lip, wherein the seal body is arranged on a fixed component of the wheel bearing arrangement and the sealing lip abuts a sealing surface of a rotating component of the wheel bearing arrangement. The disclosure is distinguished in that a film is applied to the sealing surface.

First claim

Opening claim text (preview).

The invention claimed is: 1. A seal arrangement for a wheel bearing arrangement of a motor vehicle, comprising: a seal body having a plurality of sealing lips, wherein the seal body is arranged on a fixed component of the wheel bearing arrangement and at least one sealing lip abuts a sealing surface of a rotating component of the wheel bearing arrangement, wherein a film is applied to the sealing surface; and wherein the film is connected to the sealing surface via an adhesive and/or a friction-locked connection, wherein the film co a first of the plurality of sealing lips but does not contact a second of the plurality of sealing lips, and wherein the fixed component of the wheel bearing arrangement is a fixed bearing ring of a roller bearing and the rotating component of the wheel bearing arrangement having the sealing surface is a wheel hub, the wheel hub comprising a circumferential groove, wherein the circumferential groove comprises a recess extending in the axial direction, wherein a base of the recess forms the sealing surface. 2. The seal arrangement as claimed in claim 1 , wherein the film has a layer thickness (d) of ≤0.3 mm. 3. The seal arrangement as claimed in claim 2 , wherein the film is made of plastic, metal, or composite material. 4. The seal arrangement as claimed in claim 2 , wherein the film has a surface quality having a roughness depth (Rz) of Rz<10 μm. 5. The seal arrangement as claimed in claim 1 , wherein the friction-locked connection is produced by means of shrinking. 6. The seal arrangement as claimed in claim 5 , wherein the film is made of plastic, metal, or composite material. 7. The seal arrangement as claimed in claim 5 , wherein the film has a surface quality having a roughness depth (Rz) of Rz<10 μm. 8. The seal arrangement as claimed in claim 1 , wherein the film is made of plastic, metal, or composite material. 9. The seal arrangement as claimed in claim 8 , wherein the film has a surface quality having a roughness depth (Rz) of Rz<10 μm. 10. The seal arrangement as claimed in claim 1 , wherein the film has a surface quality having a roughness depth (Rz) of Rz<10 μm.
