Abstract
Description
Die Erfindung betrifft ein Verfahren zur Montage von auf geschobenen Lagerinnenringen auf einer Radnabe, bei dem sich der oder die Lagerinnenringe an einer Ringschulter an der Radnabe axial abstützen und mittels eines Spann elements dagegen axial verspannt gehalten sind. Die Rad lager der genannten Art sind in der Regel als zweireihige Rillenkugellager ausgeführt, wobei ggfs. ein innerer Lagerring einstückig mit der Radnabe sein kann, während der zweite innere Lagerring ein separates Bauteil dar stellt und aufgeschoben ist; es können auch zwei separat von der Radnabe ausgebildete Lagerinnenringe vorgesehen sein, die aufgeschoben werden und sich an einer Ringschul ter der Radnabe abstützen. Geeignete Spannmittel werden verwendet, um eine axiale Lagervorspannung zu erzeugen; diese bestehen bisher aus einer auf ein Gewinde an der Radnabe aufzuziehenden Spannmutter oder aus einem von einer in die Radnabe eingeschraubten Dehnschraube beauf schlagtem Ringkörper. Dieser Ringkörper kann dabei zu gleich ein Bauteil eines anschließenden Drehgelenks sein.The invention relates to a method for mounting on pushed inner bearing rings on a wheel hub where the bearing ring or rings on a ring shoulder Support the wheel hub axially and by means of a clamp elements, on the other hand, are held axially braced. The wheel Bearings of the type mentioned are usually double-row Deep groove ball bearings executed, if necessary an inner Bearing ring can be integral with the wheel hub while the second inner bearing ring is a separate component poses and is postponed; it can also be two separately bearing inner rings formed by the wheel hub are provided be who are put off and join a ring school Support the wheel hub. Suitable clamping devices used to create an axial bearing preload; So far, these consist of a thread on the Wheel hub to be tightened or from one of an expansion screw screwed into the wheel hub struck ring body. This ring body can be a component of a subsequent swivel joint.
Radlager mit separaten Lagerinnenringen neigen nach einer gewissen Laufzeit zur Vergrößerung des axialen Lager spiels. Hauptursache sind Verschleiß durch Mikroreibung (Passungsrost) und Nachgeben (Setzen) aller axialen An lageflächen zwischen den Anlageschultern an der Radnabe, den Lagerinnenringen und den Spannmitteln. Wheel bearings with separate bearing inner rings tend to one certain runtime to enlarge the axial bearing play. The main cause is wear caused by micro-friction (Fretting corrosion) and yielding (setting) of all axial connections contact surfaces between the contact shoulders on the wheel hub, the bearing inner rings and the clamping devices.
Aufgabe der vorliegenden Erfindung ist es, ein Verfahren bereitzustellen, mit dem das Erzeugen einer axialen Vor spannung auf die Lager und die Befestigung der Spannmittel vereinfacht wird und wobei die Zahl der Setzungserschei nungen unterworfenen Anlageflächen auf das mindeste redu ziert wird.The object of the present invention is a method to provide with the creation of an axial front tension on the bearings and the fastening of the clamping devices is simplified and the number of settlement certificates subject to minimum investment areas is decorated.
Eine erste Lösung hierfür besteht darin, daß ein hülsen förmiges Spannelement auf die Radnabe aufgeschoben wird und unter axialer mechanischer Vorspannung gegenüber dem Lagerinnenring gehalten und mit der Radnabe verschweißt wird. Insbesondere bei Verwendung einer Hülse von einer gewissen Länge, die an der Lagerring- abgewandten Seite mit der Radnabe verschweißt wird, können hier Setzungser scheinungen durch die aufgeprägte Vorspannung ausgeglichen werden.A first solution to this is that a sleeve shaped clamping element is pushed onto the wheel hub and under axial mechanical prestress against the Bearing inner ring held and welded to the wheel hub becomes. Especially when using a sleeve of one certain length, on the side facing away from the bearing ring Settlers can be welded to the wheel hub here phenomena compensated by the imprinted preload will.
Eine zweite Lösung besteht darin, daß ein hülsenförmiges Spannelement auf die zuvor erwärmte Radnabe aufgeschoben wird und in Anschlag mit dem Lagerinnenring mit der Rad nabe verschweißt wird, worauf ein Temperaturausgleich zur Erzeugung axialer mechanischer Vorspannung gegenüber dem Lagerinnenring stattfindet. Die Erzeugung der Vorspannung erfolgt hierbei durch die Verkürzung der sich abkühlenden Radnabe, wobei sichergestellt sein muß, daß die Schweißung bereits unverformbar ausgekühlt ist, bevor der Temperatur ausgleich zwischen Radnabe und Lagern stattfindet. Es ist selbstverständlich, daß die Maßnahme nach der zuvor ge nannten Lösung, d. h. ein Aufbringen einer mechanischen Vorspannung auf das Spannmittel, hierbei zusätzlich ange wendet werden kann. A second solution is that a sleeve-shaped Clamping element pushed onto the previously heated wheel hub is and in contact with the bearing inner ring with the wheel hub is welded, whereupon a temperature compensation for Generation of axial mechanical preload against the Inner bearing ring takes place. The generation of the preload takes place here by shortening the cooling Wheel hub, it must be ensured that the weld has already cooled undeformably before the temperature compensation takes place between wheel hub and bearings. It is of course, that the measure after the previously ge called solution, d. H. an application of a mechanical Preload on the clamping device, additionally attached here can be applied.
Eine dritte Lösung besteht darin, daß zuvor unterkühlte Lagerinnenringe auf die Radnabe aufgeschoben werden und ein hülsenförmiges Spannelement mit diesen in Anschlag gebracht und mit der Radnabe verschweißt wird, worauf ein Temperaturausgleich zur Erzeugung axialer mechanischer Vorspannung stattfindet. Soweit es den Schweißvorgang nicht behindert, kann auch die Hülse hierbei unterkühlt werden. Es ist auch hier wiederum erforderlich, daß die Schweißung bis zur Erhärtung ausgekühlt ist, bevor der Temperaturausgleich stattfindet. Auch das hier genannte Verfahren kann mit einem oder beiden der zuvor genannten Verfahren kombiniert werden, d. h. eine zusätzliche mecha nische Vorspannung und eine zusätzliche Erwärmung der Rad nabe sind möglich.A third solution is that previously hypothermic Inner bearing rings are pushed onto the wheel hub and a sleeve-shaped clamping element with these in stop brought and welded to the wheel hub, what a Temperature compensation for the generation of axial mechanical Preload takes place. So much for the welding process not hindered, the sleeve can also be supercooled will. Again, it is necessary that the Weld has cooled to hardening before the Temperature compensation takes place. Also the one mentioned here Process can be done with one or both of the above Methods are combined, d. H. an additional mecha niche preload and additional heating of the wheel hubs are possible.
In weiterer Ausgestaltung des genannten Verfahrens ist es auch möglich, zwischen das Spannelement und die Lager innenringe eine Dehnhülse zu setzen. Die Zahl der Anlage flächen erhöht sich hierdurch; dafür kann jedoch die Dehn hülse in einem größeren Maße zum Ausgleich von Setzungs erscheinungen axial vorgespannt werden.In a further embodiment of the method mentioned, it is also possible between the clamping element and the bearing to put an expansion sleeve on the inner rings. The number of the plant this increases areas; for that, however, the Dehn sleeve to a greater extent to compensate for settlement phenomena are biased axially.
Nach einer ersten einfachen Durchführung des Verfahrens wird eine Schweißverbindung im axial offenen Passungsspalt zwischen Radnabe und Spannelement erzeugt. Eine alterna tive Ausführung besteht darin, daß die Schweißverbindung radial durch das Spannelement hindurch unter Verbindung mit der Radnabe erzeugt wird. Die insbesondere mit Laser zu erzeugende Schweißung, die dadurch auch eine sehr gute Energiezufuhrregelung möglich macht, kann hierbei in einer Umfangsnut im Spannelement eingebracht werden, die so bemessen ist, daß das Material die erforderliche Dicke hat. In beiden Fällen soll die Schweißung an dem von den Lagerinnenringen abgewandten Ende des hülsenförmigen Spannelementes erzeugt werden. After a first simple implementation of the procedure becomes a welded joint in the axially open fit gap generated between wheel hub and clamping element. An alterna tive execution is that the welded joint radially through the clamping element with connection is generated with the wheel hub. Which especially with laser weld to be produced, which also makes it a very good weld Energy supply control makes it possible in one Circumferential groove are introduced in the clamping element, so is sized so that the material has the required thickness Has. In both cases, the weld should be on the one of the End of the sleeve-shaped bearing inner rings facing away Clamping element are generated.
