2511-ll-DE2511-ll-DE
Die vorliegende Neuerung betrifft eine Drehgelenk, insbesondere für Rückenlehnen von Kraftfahrzeugsitzen, bei dem zwei gegeneinander bewegbare Gelenkteile über eine Schwenkachse miteinander verbunden sind, wobei eine die Lage der beiden Gelenkteile zueinander bestimmende, als Getriebe mit wenigstens einem Innenzahnrad und wenigstens einem damit kämmenden Stirnzahnrad ausgebildete Verstelleinrichtung vorgesehen ist, die einen auf der Schwenkachse angeordneten und mit diesem einstückig verbundenen Exzenter aufweist.The present innovation relates to a swivel joint, in particular for backrests of motor vehicle seats, in which two joint parts that can move relative to one another are connected to one another via a swivel axis, wherein an adjusting device that determines the position of the two joint parts relative to one another is provided, designed as a gear with at least one internal gear and at least one spur gear that meshes with it, which has an eccentric arranged on the swivel axis and connected to it in one piece.
Ein derartiges Drehgelenk ist beispielsweise in der DE-C-31 18 896 offenbart. Die Schwenkachse ist mittels einer Bundbuchse gegenüber dem einem Gelenkteil gleitgelagert und gegenüber beiden Gelenkteilen in axialer Richtung dadurch gesichert, daß der Exzenter bei Überschreiten seines Axialspiels mit seinen beiden axialen Stirnflächen an beiden Gelenkteilen bzw. der Bundbuchse anliegt. Die Gleitreibung zwischen dem Exzenter und den Gelenkteilen bzw. der Bundbuchse beeinflußt den Kraftaufwand zur Betätigung der Verstelleinrichtung in ungünstiger Weise.Such a swivel joint is disclosed, for example, in DE-C-31 18 896. The swivel axis is supported by a flanged bushing in relation to one joint part and is secured in the axial direction relative to both joint parts by the fact that the eccentric, when its axial play is exceeded, rests with its two axial end faces on both joint parts or the flanged bushing. The sliding friction between the eccentric and the joint parts or the flanged bushing has an unfavorable effect on the force required to operate the adjustment device.
Aufgabe der vorliegenden Neuerung ist es daher, die Reibung zwischen den Stirnflächen des Exzenters und anderen Flächen zu verringern und somit den Verstellvorgang des Drehgelenkes zu erleichtern.The purpose of this innovation is therefore to reduce the friction between the front surfaces of the eccentric and other surfaces and thus to facilitate the adjustment process of the swivel joint.
Neuerungsgemäß wird diese Aufgabe dadurch gelöst, daß an einander zugewandten Mantelflächen des einen Gelenkteiles und der Schwenkachse zueinander konzentrische Laufrillen ausgebildet sind, an denen Kugeln abwälzen. Diese neuerungsgemäß vorgesehene Wälzlagerung bewirkt eine axiale Festlegung der Schwenkachse , so daß der Exzenter keine unzu-According to the innovation, this task is solved by forming concentric grooves on the facing surfaces of one joint part and the pivot axis, on which balls roll. This roller bearing provided according to the innovation ensures an axial fixation of the pivot axis, so that the eccentric does not have any undue
2511-11-DE 22511-11-EN 2
lässigen axialen Bewegungen durchführen kann, die zu einem unerwünschten Gleitkontakt seiner radialen Stirnflächen mit anderen Bauteilen führt. Neben der Ausbildung von einander gegenüberliegenden Laufrillen, in denen die Kugeln axial beidseitig geführt sind, ist selbstverständlich möglich, Laufrillen für Schrägkugellager auszubilden; in letzerem Fall kann es bekanntermaßen sinnvoll sein, beispielsweise zwei Schrägkugellager derart axial benachbart vorzusehen, daß in beiden axialen Richtungen wirkende Belastungen über die Kugel lagerung geleitet werden.can perform casual axial movements, which leads to undesirable sliding contact between its radial end faces and other components. In addition to the formation of opposing raceways in which the balls are guided axially on both sides, it is of course possible to form raceways for angular contact ball bearings; in the latter case it can be useful, for example, to provide two angular contact ball bearings axially adjacent in such a way that loads acting in both axial directions are guided via the ball bearing.
Eine vorteilhafte Weiterbildung des neuerungsgemäßen Drehgelenks besteht gemäß Anspruch 2 darin, daß wenigstens die der Schwenkachse zugehörige Laufrille durch Materialumformung gebildet ist. So ist es beispielsweise möglich, daß die zunächst glatte Mantelfläche der hohlen Schwenkachse durch deren radiales Aufweiten in Richtung auf die radial äußere Laufrille vergrößert wird, wobei die in der äußeren Laufrille angeordneten und unter hoher Radialbelastung stehenden Kugeln bei Drehung der Schwenkachse die innere Laufrille in die Mantelfläche der Schwenkachse hineindrücken. Auf diese Weise ist es möglich, ein vollkugeliges Wälzlager für hohe Traglasten zu schaffen. Eine andere Möglichkeit für die Materialumformung besteht darin, daß lediglich bei einer Laufrille zu einer axialen Seite noch keine radiale Erhöhung zur Kugelführung vorgesehen ist. In diesem Fall können die Kugeln bequem zwischen die Laufrillen eingeführt werden, wobei anschließend durch axiales Stauchen die fehlende radiale Erhöhung an der einen Laufrille gebildet wird.An advantageous further development of the swivel joint according to claim 2 consists in that at least the raceway associated with the swivel axis is formed by material deformation. For example, it is possible for the initially smooth outer surface of the hollow swivel axis to be enlarged by radially widening it in the direction of the radially outer raceway, whereby the balls arranged in the outer raceway and subjected to high radial load press the inner raceway into the outer surface of the swivel axis when the swivel axis rotates. In this way, it is possible to create a full-ball rolling bearing for high loads. Another possibility for material deformation is that only in one raceway on one axial side no radial elevation is provided for ball guidance. In this case, the balls can be easily inserted between the raceway grooves, whereby the missing radial elevation on one raceway is then formed by axial compression.
Gemäß Anspruch 3 ist es zweckmäßig, daß an der einen Mantelfläche eine zylindrische Klemmbahn und an der anderen Mantelfläche wenigstens eine rampenförmige Klemmbahn ausgebildet sind, wobei wenigstens eine Klemmrolle gegen die einander zugewandten Klemmbahnen angefedert ist. Dieses Klemmgesperre verhindert unerwünschte Drehbewegungen der Schwenkachse gegenüber dem einen Gelenkteil, so daß die beiden Gelenkteile in ihrer aktuellen Stellung zueinander fixiert sind.According to claim 3, it is expedient that a cylindrical clamping track is formed on one surface and at least one ramp-shaped clamping track is formed on the other surface, with at least one clamping roller being spring-loaded against the clamping tracks facing each other. This clamping mechanism prevents undesired rotational movements of the pivot axis relative to one joint part, so that the two joint parts are fixed in their current position relative to each other.
Gemäß Anspruch 4 ist es zweckmäßig, daß Finger eines drehbaren Betätigungsgliedes zum Herausdrücken der Klemmrollen aus dem KlemmbereichAccording to claim 4, it is expedient that fingers of a rotatable actuating member for pushing the clamping rollers out of the clamping area
2511-11-DE 32511-11-EN 3
der Klemmbahnen vorgesehen sind, wobei die Finger am Umfang der Klemmrollen angreifen. Das Betätigungsglied kann beispielsweise als Handrad ausgebildet sein, für dessen Finger gemäß Anspruch 5 Anschlagflächen an der Schwenkachse ausgebildet sind. Bei Drehung des Handrades schlagen die Finger schließlich gegen die Anschlagflächen an und drehen bei weiterer Drehbewegung die Schwenkachse mit dem Exzenter mit, so daß eine Taumelbewegung und damit eine Veränderung der Lage der beiden Gelenkteile zueinander durchgeführt wird.the clamping tracks are provided, with the fingers engaging the circumference of the clamping rollers. The actuating member can be designed, for example, as a handwheel, for whose fingers stop surfaces are designed on the swivel axis according to claim 5. When the handwheel is rotated, the fingers finally strike against the stop surfaces and, as the rotation continues, the swivel axis rotates with the eccentric, so that a wobbling movement and thus a change in the position of the two joint parts relative to one another is carried out.
Gemäß Anspruch 6 ist es zweckmäßig, daß das eine Gelenkteil eine Innenverzahnung und das andere Gelenkteil eine mit der Innenverzahnung kämmende Stirnverzahnung aufweist, wobei der Exzenter in Gleitkontakt mit einer zur Schwenkachse konzentrischen Bohrung eines der Gelenkteile steht.According to claim 6, it is expedient that one joint part has an internal toothing and the other joint part has a spur toothing meshing with the internal toothing, wherein the eccentric is in sliding contact with a bore of one of the joint parts that is concentric with the pivot axis.
Nachstehend wird das neuerungsgemäße Drehgelenk anhand eines in den Figuren 1 bis 5 dargestellten Ausführungsbeispieles näher erläutert. Es zeigen:The new swivel joint is explained in more detail below using an example shown in Figures 1 to 5. The figures show:

Das Drehgelenk nach Figur 1 weist zwei Gelenkteile 1, 2 auf, die mittels einer Schwenkachse 3 miteinander verbunden sind. Zum Aufzeigen unterschiedlicher Ausführungen ist die abgebildete Schwenkachse 3 oberhalb ihrer Mittelachse aus Rohrmaterial und unterhalb ihrer Mittelachse aus Vollmaterial hergestellt.

To show different designs, the swivel axis 3 shown is made of tubular material above its central axis and of solid material below its central axis. The joint part 1 has a cylindrical axial section 4, on the inner surface 5 of which a
2511-11-DE 42511-11-EN 4
Laufrille 6 für Kugeln 7 ausgebildet ist. An einer Außenmantelflache 8 der Schwenkachse 3 ist ebenfalls eine Laufrille 9 für die Kugeln 7 ausgebildet. Weiterhin weist die Schwenkachse 3 einen Exzenter 10 auf. In das Gelenkteil 1 ist eine Stirnverzahnung 11 eingeprägt, die mit einer Innenverzahnung 12 des Gelenkteils 2 kämmt.A running groove 6 is formed for balls 7. A running groove 9 for the balls 7 is also formed on an outer surface 8 of the pivot axis 3. The pivot axis 3 also has an eccentric 10. A spur gear 11 is embossed into the joint part 1, which meshes with an internal gear 12 of the joint part 2.
Die Zähnezahl der Innenverzahnung 12 und der Stirnverzahnung 11 unterscheiden sich um wenigstens einen Zahn. Das Gelenkteil 2 weist eine den Exzenter 10 umfassende Bohrung 13 auf, die konzentrisch zur Schwenkachse 3 ist. Der Exzenter 10 steht im Gleitkontakt mit dieser Bohrung 13.The number of teeth of the internal toothing 12 and the spur toothing 11 differs by at least one tooth. The joint part 2 has a bore 13 which encompasses the eccentric 10 and is concentric to the pivot axis 3. The eccentric 10 is in sliding contact with this bore 13.
Weiterhin ist ein um die Schwenkachse 3 begrenzt schwenkbares Betätigungsglied 14 vorgesehen, das mit einem Klemmgesperre 15 zusammenarbeitet, das eine Drehung der Schwenkachse 3 gegenüber dem Gelenkteil 1 wahlweise sperrt oder ermöglicht.Furthermore, an actuating member 14 is provided which can be pivoted to a limited extent about the pivot axis 3 and which works together with a clamping lock 15 which selectively blocks or enables rotation of the pivot axis 3 relative to the joint part 1.
Figur 2 zeigt eine Draufsicht auf das Klemmgesperre 15, das in der Ausschnittsvergrößerung in Figur 3 näher erläutert wird.Figure 2 shows a top view of the clamping mechanism 15, which is explained in more detail in the enlarged detail in Figure 3.
Mit dem hier nicht dargestellten Betätigungsglied 14 verbundene axiale Schaltfinger 16 ragen in den von den Mantelflächen 5, 8 begrenzten Ringraum hinein. An der Außenmantelflache 5 ist eine Klemmbahn 17 und an der Innenmantelfläche 8 ist eine rampenförmige Klemmbahn 18 ausgebildet, wobei zwischen den Klemmbahnen 17, 18 vorgesehene Klemmrollen 19 mittels einer Feder 20 gegen die Klemmbahnen 17, 18 angefedert sind. An in Umfangsrichtung benachbarten Absätzen der rampenförmigen Klemmbahn 18 sind Anschlagflächen 21 für die Schaltfinger 16 ausgebildet, die zu diesem Zweck mit Stoppflächen 22 versehen sind, die die Anschlagflächen 21 radial wenigstens teilweise überlappen.Axial switching fingers 16 connected to the actuating element 14 (not shown here) protrude into the annular space delimited by the casing surfaces 5, 8. A clamping track 17 is formed on the outer casing surface 5 and a ramp-shaped clamping track 18 is formed on the inner casing surface 8, whereby clamping rollers 19 provided between the clamping tracks 17, 18 are spring-loaded against the clamping tracks 17, 18 by means of a spring 20. Stop surfaces 21 for the switching fingers 16 are formed on adjacent shoulders of the ramp-shaped clamping track 18 in the circumferential direction, which are provided for this purpose with stop surfaces 22 which radially at least partially overlap the stop surfaces 21.
Dieses Klemmgesperre 15 ist in der Figur 4 im Längsschnitt in vergrößerter Darstellung abgebildet. Dieser Figur ist deutlich zu entnehmen, daß die Klemmrollen 19 in bauraumsparender Weise axial unmittelbar neben den Kugeln 7 angeordnet ist.This clamping mechanism 15 is shown in Figure 4 in an enlarged longitudinal section. It can be clearly seen from this figure that the clamping rollers 19 are arranged axially directly next to the balls 7 in a space-saving manner.

Figur 5 zeigt eine Stirnansicht des neuerungsgemäßen Drehgelenkes, wobei in dieser Darstellung die Lage des Exzenters 10 in der Bohrung 13 deutlich sichtbar abgebildet ist.Figure 5 shows a front view of the new swivel joint, where the position of the eccentric 10 in the bore 13 is clearly visible in this illustration.
Nachstehend wird die Funktion des anhand der Figuren 1-5 oben beschriebenen Drehgelenkes erläutert:The function of the swivel joint described above in Figures 1-5 is explained below:
Bei Drehung des Betätigungsgliedes 14 in einer Richtung kommt der Schaltfinger 16 zur Anlage an der ihm benachbarten Klemmrolle 19 und drückt diese aus dem Klemmbereich der Klemmbahnen 17, 18. Bei einer weiteren Drehbewegung erfolgt der Kontakt zwischen der Stoppfläche 22 und der Anschlagfläche 21, so daß die Schwenkachse 3 mitgedreht wird. Mit der Schwenkachse 3 dreht der Exzenter 10, der im Gleitkontakt mit der Bohrung 13 des Gelenkteils 2 steht. Durch die Exzenterbewegung wird das Gelenkteil 2 zu Taumel bewegungen gegenüber dem Gelenkteil 1 gezwungen. Die Zähnezahlen der Innenverzahnung 12 und der Stirnverzahnung 11 unterscheiden sich um wenigstens einen Zahn, so daß bei Drehung der Schwenkachse 3 mit der Taumelbewegung eine Relativdrehung der beiden Gelenkteile 1, 2 zustandekommt. Ist die gewünschte Lage der Gelenkteile 1, 2 zueinander erreicht, wird das beispielsweise als Handrad ausgebildete Betätigungsglied 14 losgelassen, wobei unter Einwirkung der Feder 20 die Klemmrollen 19 gegen die Klemmbahnen 17, 18 angefedert werden, so daß eine Drehbewegung der Schwenkachse 3 gegenüber dem Gelenkteil 1 und damit auch eine Bewegung zwischen den beiden Gelenkteilen 1, 2 verhindert wird.When the actuating member 14 is rotated in one direction, the switching finger 16 comes into contact with the clamping roller 19 adjacent to it and pushes it out of the clamping area of the clamping tracks 17, 18. With a further rotation, contact is made between the stop surface 22 and the stop surface 21, so that the pivot axis 3 is also rotated. The eccentric 10, which is in sliding contact with the bore 13 of the joint part 2, rotates with the pivot axis 3. The eccentric movement forces the joint part 2 to wobble relative to the joint part 1. The number of teeth of the internal toothing 12 and the spur toothing 11 differ by at least one tooth, so that when the pivot axis 3 rotates with the wobbling movement, a relative rotation of the two joint parts 1, 2 occurs. If the desired position of the joint parts 1, 2 relative to one another is reached, the actuating member 14, which is designed as a handwheel, for example, is released, whereby the clamping rollers 19 are spring-loaded against the clamping tracks 17, 18 under the action of the spring 20, so that a rotational movement of the pivot axis 3 relative to the joint part 1 and thus also a movement between the two joint parts 1, 2 is prevented.
Das Gelenkteil 2 kann mit einer nicht dargestellten Rückenlehne und das Gelenkteil 1 mit einer nicht dargestellten Sitzfläche verbunden sein.The joint part 2 can be connected to a backrest (not shown) and the joint part 1 can be connected to a seat (not shown).
