Description
Diese Erfindung betrifft im allgemeinen ein Verfahren zum Befestigen einer Abdichtung an einem zylindrischen Gehäu se. Insbesondere betrifft diese Erfindung das Befestigen einer Abdichtung an einem Gleichlaufgelenkgehäuse und einer Welle.This invention relates generally to a method for Attach a seal to a cylindrical housing se. In particular, this invention relates to fastening a seal on a constant velocity joint housing and a wave.
Bei Fahrzeugen mit Vorderradantrieb wird zur Kraftüber tragung vom Verteilergetriebe zu den Vorderrädern ein Paar von Halbwellenanordnungen verwendet. Jede Halbwellenanord nung umfaßt ein Paar von Gleichlaufgelenken, die durch eine Verbindungswelle verbunden sind. Ein Gleichlaufgelenk ist mit dem Vorderrad verbunden. Das andere Gleichlauf gelenk ist mit dem Verteilergetriebe verbunden.In vehicles with front-wheel drive, power is transferred transmission from the transfer case to the front wheels a pair of half-wave arrangements used. Any half-wave arrangement tion includes a pair of constant velocity joints that pass through a connecting shaft are connected. A constant velocity joint is connected to the front wheel. The other synchronism joint is connected to the transfer case.
Das am Rad angeordnete Gleichlaufgelenk ist ein Gleich laufgelenk mit feststehendem Mittelpunkt (Festgelenk). Dieses Gelenk ist für große Winkel (45°-50°) geeignet. Durch die große Winkelkapazität dieses Gelenks können die Vorderräder die Lenkwinkel einnehmen.The constant velocity joint arranged on the wheel is an equal running joint with a fixed center point (fixed joint). This joint is suitable for large angles (45 ° -50 °). Due to the large angular capacity of this joint, the Front wheels take up the steering angle.
Das an der Hinterachse angeordnete Gleichlaufgelenk ist ein Verschiebe-Gleichlaufgelenk. Dieses Gelenk weist einen beweglichen Mittelpunkt auf und ist für Winkel von 20° bis 25° geeignet. Der bewegliche Mittelpunkt ermöglicht ge meinsam mit der Winkelkapazität des Gelenks Bautoleranzen wie auch Bewegungen der Aufhängung und Motorvibrationen.The constant velocity joint located on the rear axle is a sliding constant velocity joint. This joint has one moving center and is for angles from 20 ° to 25 ° suitable. The movable center enables ge common with the angular capacity of the joint construction tolerances as well as movements of the suspension and engine vibrations.
Gleichlaufgelenke müssen ständig mit Schmiermittel, in dem sie arbeiten, versorgt werden. Normalerweise ist dieses Schmiermittel in einer Kammer enthalten, die durch eine Abdichtung oder einen Balg gebildet wird. Die Abdichtung besteht üblicherweise aus elastischem Material, entweder Gummi oder Kunststoff. Der Balg wird mit einem Ende an dem äußeren Durchmesser des Gleichlaufgelenks befestigt. Das andere Ende ist an der Verbindungswelle angebracht. Diese Anordnung erzeugt eine im allgemeinen konisch geformte Kammer, die während des Zusammenbaus der Halbwelle mit einer vorbestimmten Menge von Schmierfett gefüllt wird. Dieses Schmierfett reicht normalerweise für die Schmierung des Gleichlaufgelenks während der gesamten Lebensdauer des Fahrzeuges.Constant velocity joints must be lubricated constantly in the they work, are cared for. Usually this is Lubricant contained in a chamber through a Sealing or a bellows is formed. The seal usually consists of elastic material, either Rubber or plastic. The bellows ends with one end fixed outer diameter of the constant velocity joint. The the other end is attached to the connecting shaft. These The arrangement creates a generally conical shape Chamber that during assembly of the half-wave with a predetermined amount of grease is filled. This grease is usually sufficient for lubrication of the constant velocity joint throughout the life of the Vehicle.
Die Abdichtungen der Gleichlaufgelenke sind kritische Bestandteile der Halbwellenanordnung, da sie eine konti nuierliche Versorgung mit Schmiermittel benötigen. Wenn aus irgendeinem Grund die Abdichtung versagt, wäre dieses Versagen im Prinzip für den Fahrer des Fahrzeuges nicht erkennbar. Sobald das Schmiermittel durch die Abdichtung aus der Anordnung lecken kann, tritt kurz danach ein Ver sagen des Gleichlaufgelenks ein.The seals of the constant velocity joints are critical Components of the half-wave arrangement, since they are a continuous need a lubricant supply. If for some reason the seal would fail In principle, the driver of the vehicle does not fail recognizable. Once the lubricant through the seal can leak from the arrangement, shortly afterwards a Ver say the constant velocity joint.
Die Elastizität des Abdichtung ermöglicht die winkelige Bewegung der Welle in bezug auf das Gehäuse des Gleich laufgelenks. Während der Abwinkelung des Gelenks wird der Balg auf einer Seite zyklisch komprimiert, während er auf der gegenüberliegenden Seite ausgedehnt wird. Wenn das Gelenk unter Abwinkelung arbeitet, erfährt der Balg eine zyklische Kompression und Längsausdehnung. Die Frequenz dieses zyklischen Vorgangs hängt von der Drehgeschwindig keit des Gelenks ab.The elasticity of the seal allows the angular Movement of the shaft in relation to the housing of the match running joint. During the bending of the joint, the Bellows cyclically compressed on one side while it is on on the opposite side. If that If the joint works under angulation, the bellows experiences one cyclic compression and longitudinal expansion. The frequency this cyclical process depends on the rotational speed of the joint.
Frühere Abdichtungen von Gleichlaufgelenken wurden aus Gummi oder Neoprenmaterial hergestellt. Dieses Material weist eine ausgezeichnete Elastizität auf und kann leicht an dem Gehäuse des Gleichlaufgelenks und an der Welle durch ein Metallband festgelegt werden. Die Leistung dieser Gummiab dichtungen ist zwar angemessen, aber das weiche Gummimate rial macht sie für Quetschlöcher anfällig.Earlier seals of constant velocity joints were made of rubber or neoprene material. This material points excellent elasticity and can be easily attached to the Housing of the constant velocity joint and on the shaft through one Metal tape to be set. The performance of this rubber Seals are appropriate, but the soft rubber air rial makes them vulnerable to pinch holes.
Der Gummibalg kann während der Handhabung der Halbwelle, während des Zusammenbaus des Fahrzeuges oder durch den Kontakt der Kappe mit anderen Bestandteilen des Fahrzeuges während des Zusammenbaus des Fahrzeuges durchlöchert wer den. Die Gummibälge können, sobald sie richtig zusammen gebaut sind, durch Straßenhindernisse, von Mechanikern verwendete Brechstangen, Abschlepphaken oder andere Gegen stände, die den Balg zwischen dem Gegenstand und einem der anderen Halbwellenbestandteile einklemmen, beschädigt werden.The rubber bellows can be during the assembly of the vehicle or by the Contact of the cap with other components of the vehicle holed during the assembly of the vehicle the. The rubber bellows can be put together as soon as they are properly are built, by road obstacles, by mechanics used crowbars, tow hooks or other counter stands that the bellows between the object and one of the Pinch other half-wave components, damaged will.
Kunststoffbälge, normalerweise aus Dupont Hytrel®, wurden zur Verringerung oder Vermeidung der Anfälligkeit für Quetschlöcher entwickelt. Das Kunststoffmaterial ist widerstandsfähiger als das Gummimaterial und kann einem vernünftigen Maß an Fehlbehandlung und anderem Mißbrauch widerstehen, das bei einem Gummibalg Quetschlöcher hervor riefe.Plastic bellows, usually made of Dupont Hytrel®, were used to reduce or avoid vulnerability developed for pinholes. The plastic material is more resistant than the rubber material and can one reasonable level of misconduct and other abuse Resist that pinch holes from a rubber bellows called.
Leider ist mit der erhöhten Widerstandsfähigkeit die Schwierigkeit verbunden, die Kunststoffbälge an den äuße ren Gelenkhälften und den Wellen der Halbwellenanordnungen zu befestigen. Das Kunststoffmaterial erfordert ein Me tallband mit einem größeren Querschnitt, um den Balg an den Bestandteilen der Halbwelle während des Betriebs zu befestigen und abzudichten. Außer einer Vergrößerung des Querschnitts erfolgt eine Umstellung des Materials des Metallbandes von einem billigen galvanisierten Stahl zu einem verhältnismäßig teuren rostfreien Stahl. Die Ver größerung des Querschnitts gemeinsam mit der Umstellung auf ein teures Material hat die Kosten des Befestigungs systems des Balgs erheblich erhöht.Unfortunately, with the increased resilience Difficulty linked to the plastic bellows on the outer Ren joint halves and the waves of the half-wave arrangements to fix. The plastic material requires a me tallband with a larger cross section to the bellows the components of the half-wave during operation fasten and seal. Except for an enlargement of the The material of the cross section is changed Metal strip from a cheap galvanized steel too a relatively expensive stainless steel. The Ver enlargement of the cross-section together with the changeover on an expensive material has the cost of attachment system of the bellows significantly increased.
Demgemäß wird ein Verfahren zum Befestigen der Kunststoff bälge von Gleichlaufgelenken an einer Halbwellenanordnung angestrebt, das mit geringen Kosten verbunden und zuver lässig ist.Accordingly, there is a method of attaching the plastic Bellows of constant velocity joints on a half-shaft arrangement aimed at that associated with low costs and verver is casual.
Die vorliegende Erfindung bietet der Technik ein Verfahren zum Befestigen eines Kunststoffbalges an einer Halbwellen anordnung. Der Balg wird in Position gebracht und dann erwärmt, um den Balg zu schrumpfen und an die Halbwellen anordnung anzupassen.The present invention provides a technique to the art for attaching a plastic bellows to a half shaft arrangement. The bellows is positioned and then heated to shrink the bellows and to the half waves to adapt the arrangement.

Die detaillierte Beschreibung gilt der Befestigung einer Kunststoffabdichtung an einem Ende eines Kugelgleichlauf gelenks mit feststehendem Mittelpunkt (Festgelenk) einer Halbwellenanordnung. Es wird davon ausgegangen, daß ein Fachmann die hierin beschriebenen Befestigungsverfahren übernehmen und bei den anderen Arten von Drehgelenken anwenden kann.The detailed description applies to the attachment of a Plastic seal at one end of a ball synchronism joints with a fixed center (fixed joint) one Half wave arrangement. It is assumed that a Those skilled in the art will appreciate the fastening methods described herein take over and with the other types of swivel joints can apply.
Mit Bezugnahme auf die Zeichnungen und insbesondere auf die Fig. 1 und 2 ist ein Ende einer Halbwelle mit einem Gleichlaufgelenk mit feststehender Mitte gezeigt und mit dem Bezugszeichen 10 versehen.With reference to the drawings and in particular to FIGS. 1 and 2, one end of a half shaft with a constant velocity joint with a fixed center is shown and provided with the reference number 10 .
Das Befestigungsverfahren beginnt mit dem Anordnen einer Kunststoffabdichtung 20 über eine Verbindungswelle 22. Die Kunststoffabdichtung wird aus Dupont Hytrel® durch in der Technik gut bekannte Blasformverfahren hergestellt. Das kleine Ende der Abdichtung 24 wird in einer Nut 26 positioniert, die an der Oberfläche 28 der Verbindungs welle 22 ausgebildet ist. Dadurch wird ein Ende der Ab dichtung 20 in bezug auf das Ende der Verbindungswelle 22 angeordnet.The fastening method begins with the arrangement of a plastic seal 20 via a connecting shaft 22 . The plastic seal is made from Dupont Hytrel® using blow molding techniques well known in the art. The small end of the seal 24 is positioned in a groove 26 which is formed on the surface 28 of the connecting shaft 22 . As a result, one end of the seal 20 is arranged with respect to the end of the connecting shaft 22 .
Die Verbindungswelle 22 und die Abdichtung 20 werden dann mit der Gleichlaufgelenkanordnung 30 zusammengebaut. Nor malerweise sind die Verbindungswelle 22 und die innere Gelenkhälfte 32 des Gleichlaufgelenks durch Wellenverzah nungsmittel 34 verbunden, wie in Fig. 1 dargestellt ist. The connecting shaft 22 and the seal 20 are then assembled with the constant velocity joint assembly 30 . Normally, the connecting shaft 22 and the inner joint half 32 of the constant velocity joint are connected by means of shaft toothing means 34 , as shown in FIG. 1.
Das große Ende 36 der Abdichtung 20 wird dann über der äußeren Gelenkhälfte 38 der Gleichlaufgelenkanordnung 30 positioniert. Die Abdichtung 20 weist einen rippenförmigen Vorsprung 40 auf, der in eine Nut 42 paßt, die in der Außenfläche 44 der äußeren Gelenkhälfte 38 ausgebildet ist. Der rippenförmige Vorsprung 40 paßt mit der Nut 42 zusammen, so daß die Abdichtung 20 in bezug zu der Gleich laufgelenkanordnung 30 richtig positioniert werden kann.The large end 36 of the seal 20 is then positioned over the outer joint half 38 of the constant velocity joint assembly 30 . The seal 20 has a rib-shaped projection 40 which fits into a groove 42 which is formed in the outer surface 44 of the outer joint half 38 . The rib-shaped projection 40 mates with the groove 42 so that the seal 20 can be correctly positioned with respect to the constant velocity joint arrangement 30 .
Die Kammer 50, die von der Abdichtung 20, der äußeren Gelenkhälfte 36 und der Verbindungswelle 22 gebildet wird, wird dann mit der richtigen Art und Menge von Schmier mittel gefüllt.The chamber 50 , which is formed by the seal 20 , the outer joint half 36 and the connecting shaft 22 , is then filled with the correct type and amount of lubricant.
Die Enden 24 und 38 der Abdichtung 20 werden danach auf eine Temperatur etwas über ihren Schmelztemperaturen er wärmt. Dieses Erwärmen der Abdichtung kann durch Anordnen einer äußeren Wärmequelle nach in der Technik allgemein bekannten Verfahren um die Enden 24 und 38 der Abdichtung 20 erfolgen. Ein weiteres Verfahren zur Erzeugung der notwendigen Wärme wäre die Induktionserwärmung der äußeren Gelenkhälfte 36 und der Verbindungswelle 22 ebenfalls nach Verfahren, die in der Technik gut bekannt sind. Die Induk tionserwärmung der äußeren Gelenkhälfte 36 und der Verbin dungswelle 22 kann leicht auf einen bestimmten Erwärmungs bereich begrenzt werden, wobei nur die Bereiche der Ab dichtung 20 behandelt werden, die zur Befestigung bestimmt sind.The ends 24 and 38 of the seal 20 are then heated to a temperature slightly above their melting temperatures. This heating of the seal can be accomplished by placing an external heat source around the ends 24 and 38 of the seal 20 according to methods well known in the art. Another method of generating the necessary heat would be induction heating of the outer half of the joint 36 and the connecting shaft 22, also according to methods that are well known in the art. The induction heating of the outer joint half 36 and the connec tion shaft 22 can easily be limited to a certain heating area, only the areas of the seal 20 being treated which are intended for fastening.
Sobald die Schmelztemperatur der Abdichtung 20 erreicht ist, wird die Wärmequelle entfernt und die Anordnung ab kühlen gelassen. Durch das Abkühlen der Anordnung 10 paßt sich die Abdichtung 20 an die äußere Gelenkhälfte 36 und die Verbindungswelle 22 an und haftet an diesen. Once the melting temperature of the seal 20 is reached, the heat source is removed and the assembly is allowed to cool. By cooling the assembly 10 , the seal 20 adapts to the outer joint half 36 and the connecting shaft 22 and adheres to them.
Normalerweise ist die Befestigung der Abdichtung 20, so bald sie an der Gelenkanordnung 30 und der Verbindungs welle 22 wie durch das oben beschriebene Verfahren be festigt wurde, eine zuverlässige und komplette Anordnung. Zur Sicherung der Befestigung der Abdichtung 20 können Metallbänder 52 und 54 über der Abdichtung 20 befestigt werden, wie in Fig. 3 gezeigt wird. Die Metallbänder 52 und 54 wie auch das Verfahren zu deren Festziehen sind ähnlich wie bei den billigen galvanisierten Stahlbändern, die zur Halterung einer Gummidichtung verwendet werden, und sind in der Technik allgemein bekannt.Normally, the attachment of the seal 20 as soon as it is fastened to the hinge assembly 30 and the connecting shaft 22 as by the method described above be a reliable and complete arrangement. To secure the seal 20 in place , metal strips 52 and 54 may be secured over the seal 20 as shown in FIG. 3. The metal bands 52 and 54, as well as the method of tightening them, are similar to the inexpensive galvanized steel bands used to hold a rubber seal and are well known in the art.
