手の１部材であってもよい。The present invention is a method for assembling a complete double row wheel bearing having a non-separable bearing outer ring and at least one bearing inner ring fitted to a wheel hub, the single or multiple bearing inner ring being the shaft. Directionally supported by the annular shoulder of the wheel hub and axially tensioned thereto by means of a clamping element. Wheel bearings of the above type are usually embodied as double row deep groove ball bearings, optionally one bearing inner ring may be integral with the wheel hub, while the other second bearing inner ring is a separate member. It is fitted. It is also possible to provide two bearing inner rings separate from the wheel hub, which are fitted and supported by the annular shoulder of the wheel hub. Suitable clamping means are used to generate the axial preload of the bearing. It conventionally consists of a tightening nut that is screwed onto the threads of the wheel hub, or an annular body that is biased by an extension bolt that is screwed into the wheel hub. This annulus may at the same time be part of the universal joint that follows it.

After a certain operating time, there is a tendency to increase the axial play of the bearing. The main causes are friction due to minute friction (fretting corrosion) and flexure (depression) of any axial bearing surface between the abutment shoulder portion of the wheel hub, the bearing inner ring and the tightening means.

荷重は起きない。German Patent Specification No. 36 18 139 discloses a method of the above kind in which an axial tension of this kind is produced by crimping a circumferential separating joint between a wheel hub and another part. Formed by means of an annular projection, which forms a radial collar for fixing the separate bearing inner ring to the wheel hub. The annular projection, which is made of a material that has been heated so that it can be molded, can escape in the radial direction so that no axial preload is applied to the bearing inner ring. The subsequent cooling of the annular projection causes a contraction, which again reduces the axial preload, which in the extreme case is negligible, so that only an axial retention of the bearing ring takes place and the sagging phenomenon is pre-empted. No preload occurs.

【０００４】本発明の課題は、軸受に対する軸方向予荷
重の生成と締付手段の固着とが簡素になり又へたり現象
を受ける座面の数が最小限に減るようにした方法を提供
することである。The object of the present invention is to provide a method in which the production of axial preload on the bearing and the fastening of the fastening means are simplified and the number of seating surfaces subjected to the sag phenomenon is reduced to a minimum. That is.

【０００５】そのための最初の解決策は、筒状締付要素

たり現象を予荷重の印加により補償することができる。A first solution for this is to fit a tubular clamping element on the wheel hub, hold it axially with a mechanical preload against the bearing inner ring and weld it to the wheel hub. Especially when using a sleeve of a certain length which is welded to the wheel hub on the side opposite the bearing ring, the sag phenomenon can be compensated here by the application of a preload.

措置、即ち締付手段に機械的予荷重を加えることをこの
場合付加的に適用できることは自明である。A second solution is to fit the tubular clamping element on a pre-warmed wheel hub, make abutting contact with the bearing inner ring and weld it to the wheel hub, then machine axially against the bearing inner ring. The point is that temperature compensation is performed to generate a dynamic preload. In this case the preload is generated by shortening the wheel hub to be cooled, ensuring that the weld is already non-deformably cooled before temperature compensation between the wheel hub and the bearing. I have to keep it. It is self-evident that the measures according to the above solution, i.e. the mechanical preloading of the clamping means, can additionally be applied in this case.

【０００７】第３の解決策は、予め過冷した軸受内輪を

加的加熱が可能である。A third solution is to fit a pre-cooled bearing inner ring onto the wheel hub, abut the tubular clamping element with it and weld it to the wheel hub, and then mechanically preload it axially. The purpose is to perform temperature compensation to generate the load. The sleeve can also be subcooled in this case, provided that it does not interfere with the welding operation. Again, the weld must be cooled until it hardens before temperature compensation. The method pointed out here can also be used in combination with one or both of the above methods, i.e. additional mechanical preload and additional heating of the wheel hub is possible.

軸受内輪との間に弾性筒を嵌着することも可能である。

加えることができる。In a further construction of the method, it is also possible to fit an elastic tube between the clamping element and the bearing inner ring.
This increases the number of seat surfaces, but instead allows the elastic cylinder to be preloaded axially to almost compensate for the sag phenomenon.

A welded joint is created in the axially open mating gap between the wheel hub and the clamping element. An alternative embodiment consists in creating a weld joint in the radial direction through the clamping element for connection with the wheel hub. In particular, the weld produced by means of a laser also allows a very good control of the energy supply, in which case it can be provided in the circumferential groove of the clamping element, which groove ensures that the material has the required thickness. It is dimensioned. In each case, the weld should be produced at the end of the tubular clamping element remote from the bearing inner ring.
