Abstract
The invention relates to a wheel bearing assembly for motor vehicles with a bearing provided with an inner ring and an outer ring, the bearing being fitted with its outer ring into a bearing casing and the outer ring being mechanically supported in axial direction on a first side by a supporting surface provided on the bearing casing. Discrete and preferably evenly arranged stop protrusions are formed on the inner circumference of the bearing casing, the outer ring abutting thereon in axial direction on its second side, and the stop protrusions being formed by locally plastic forming the bearing casing.
Claims12
A method of manufacturing a wheel bearing assembly for motor vehicles involving the following method steps:
- a) fitting a bearing having an outer ring into a bearing casing,
- b) displacing said bearing in axial direction until the outer ring abuts on a supporting surface of the bearing casing;
- c) fixing the outer ring in said bearing casing in axial direction by machine-shaping an inner surface of the bearing casing by localized plastic deformation forming stop protrusions on the inner circumference of said bearing casing, the stop protrusions cooperating with the supporting surface to fixate the outer ring in axial direction within the bearing casing,
- wherein
- d) machine-shaping is carried out during the axial displacement of the bearing and is completed when the outer ring of the bearing abuts on the supporting surface.
A broaching tool for pressing into and fastening in a wheel bearing assembly a bearing, said tool comprising:
- a) at least one protrusion for abutment on a front face of a bearing for axially sliding bearing into a bearing casing, and
- b) at least one forming tools adapted to plastic forming of the bearing casing in such a manner that the inner diameter thereof is locally reduced by plastic deformation so that at least one stop protrusion is formed on the inner circumference of the bearing casing.
