Abstract

The invention relates to an elastic rotating bearing having two concentric rigid sleeves between which a rubber-elastic insert is provided which has rollers which are clamped in between the sleeves, have an elliptical cross-section and extend in the axial direction of the sleeves, the rollers having an elliptical cross-section in the unstressed state, and are connected by means of webs which run in the circumferential direction and are displaced radially outwards with respect to the centre of the rollers. The essential feature of this rotating bearing is that the ends of the rubber insert in each case have an annular bead which overhangs the outer metal sleeve radially and axially and which merges on the outside into an annular rib which is seated on the cylindrical surface of the inner jacket sleeve, being prestressed.

Description

Elastisches DrehlagerElastic pivot bearing

Die Erfindung bezieht sich auf ein elastisches Drehlager mit zwei konzentrischen, starren Hülsen zwischen denen eine gummielastische Einlage vorgesehen ist, die Rollen aufweist, welche zwischen den Hülsen eingespannt sind, elliptischen Querschnitt aufweisen und sich in Axialrichtung der Hülsen erstrecken, wobei die Rollen im unverspannten Zustand einen elliptischen Querschnitt aufweisen, durch in Umfangsrichtung verlaufende Stege verbunden sind, die zur Mitte der Rollen radial nach außen verschoben sind.The invention relates to an elastic pivot bearing with two concentric, rigid sleeves between which a rubber-elastic insert is provided is, which has rollers, which are clamped between the sleeves, elliptical Have cross-section and extend in the axial direction of the sleeves, the Rollers in the unstressed state have an elliptical cross-section, through webs extending in the circumferential direction are connected, which radially to the center of the rollers are shifted outwards.

Ein derartiges elastisches Drehlager ist in der Patentanmeldung P 32 25 927 beschrieben. Der Offenbarungsgehalt dieser älteren Patentanmeldung wird ausdrücklich zum Inhalt dieser vorliegenden Patentanmeldung hinzugenommen.Such an elastic pivot bearing is in the patent application P 32 25 927. The disclosure content of this earlier patent application is expressly added to the content of this present patent application.

Die beschriebenen elastischen Drehlager haben sich bei Stabilisatoren von Kraftfahrzeugen gut bewährt. Sie können die entsprechenden Dreh- und Verformungskräfte im Rahmen ihrer Aufgabe wirksam aufnehmen.The elastic pivot bearings described have proven themselves in stabilizers Well proven in motor vehicles. You can use the corresponding torsional and deformation forces take up effectively in the context of their task.

Da solche elastischen Drehlager im Fahrzeug in solchen Positionen angeordnet sind, in denen sie der Verschmutzung von der Straße her ausgesetzt sind, kann eine solche Verschmutzung zu Nachteilen bei der Dauerfunktionsfähigkeit führen.Since such elastic pivot bearings in the vehicle in such positions are arranged in which they are exposed to pollution from the street, Such contamination can lead to disadvantages in terms of long-term functionality.

Aufgabe der Erfindung ist es, das eingangs beschriebene elatische Drehlager soweit weiter auszubilden, daß es den vorgenannten Anforderungen noch besser gerecht werden kann.The object of the invention is to provide the elasticity described above To further train pivot bearings that it still meets the aforementioned requirements can do better justice.

Die Lösung dieser Aufgabe besteht erfindungsgemäß darin, daß die Stirnseiten der Gummieinlage je einen Ringwulst aufweisen, der die äußere Metallhülse radial und axial überragt und der an der Außenseite in eine Ringrippe übergeht, die unter Vorspannung auf der zylindrischen Fläche der inneren Metallhülse aufsitzt.The solution to this problem is, according to the invention, that the end faces the rubber insert each have an annular bead that radially connects the outer metal sleeve and protrudes axially and which merges on the outside into an annular rib, which below Preload rests on the cylindrical surface of the inner metal sleeve.

Durch diese zusätzliche und in einem Stück mit der Gummieinlage ausgebildeten Wülste werden die zwischen den Rollen bestehenden Hohlräume gegenüber der Außenwelt abgeschlossen. Die Abdichtung bezieht sich dabei sowohl auf die äußeren als auch auf die inneren durch die Stege getrennten Hohlräume. Das Überstehen in axialer und radialer Richtung führt außerdem zu einer Anlage an den äußeren Metallhülsenkanten. Dadurch werden eventuell mögliche axiale Verschiebungen der Gummieinlage verhindert.By this additional and formed in one piece with the rubber insert Bulges become the hollow spaces between the rollers in relation to the outside world closed. The sealing refers to both the external and the on the inner cavities separated by the webs. Surviving in axial and radial direction also leads to a contact with the outer metal sleeve edges. This prevents possible axial displacements of the rubber insert.

Die ferner vorgesehene Ringrippe bewirkt mit ihrem unter Vorspannung stehenden Aufsitzen auf der inneren Hülse, daß auch eine Abdichtung gewährleistet ist, wenn Winkelverstellungen zwischen der äußeren und der inneren Metallhülse auftreten. Die Ringrippe ist dabei soweit unter Vorspannung gesetzt, daß sie auch extreme Winkelverstellungen noch gerade zu kompensieren vermag. Die Ringrippe kann dabei zweckmäßigerweise etwas nach außen auSgewölbt sein, um die Vorspannung zum Teil in einer Biegeverformung unterzubringen. Solche Biegeverformungen schonen das Gummimaterial mehr als Verdrängungsverformungen, die mit einer starken Belastung der inneren Struktur des Materials verbunden sein können.The further provided annular rib effects with her under bias standing sitting on the inner sleeve that also ensures a seal is when angular misalignments occur between the outer and inner metal sleeves. The annular rib is pretensioned to such an extent that it also allows extreme angular adjustments can just compensate. The ring rib can expediently something be bulged outwards in order to reduce the prestress in part in a bending deformation accommodate. Such bending deformations protect the rubber material more than displacement deformations, which are associated with a heavy load on the internal structure of the material can.

Zwischen den Ringwülsten und den Stirnkanten der Rollen können umlaufende flache Ringnuten angeorndet sein.Circumferential be arranged flat ring grooves.

Dadurch wird ein Raum geschaffen, in den von den Rollen und den Ringwülsten verdrängte Gummimasse hinein ausweichen kann. Die Ringnuten haben weiter den Vorteil, daß eine Reibung zwischen den Kanten der äußeren Hülsen und den Ringwülsten im normalen Zustand weitgehend vermieden wird.This creates a space for the rollers and the annular beads displaced rubber mass can escape into it. The ring grooves also have the advantage that friction between the edges of the outer sleeves and the annular beads in normal Condition is largely avoided.

Nach einem weiteren Merkmale der Erfindung kann es vorgesehen sein, daß die Ringwülste je eine an den Kanten abgerundete radial ausgerichtete Ringfläche aufweisen. Diese Flächen können als Stoßauffangmittel dienen. Die verhältnismäßig große Fläche ermöglicht eine starke Belastbarkeit.According to a further feature of the invention, it can be provided that the annular beads each have a radially aligned annular surface rounded at the edges exhibit. These surfaces can serve as shock absorbing means. The proportionate large area enables a high load capacity.

Die Erfindung wird in Verbindung mit einer Zeichnung beispeilsweise beschrieben. Diese zeigt in Abbildung 1 einen Querschnitt in axialer Richtung und in Abbildung 2 in radialer Richtung durch das elastische Lager.The invention is exemplified in connection with a drawing described. This shows in Figure 1 a cross section in the axial direction and in Figure 2 in the radial direction through the elastic bearing.

Nach Abb. 1 liegt zwischen einer inneren Hülse t und einer äußeren Hülse 2 eine Gummieinlage 3. Die Einlage 3 besteht aus Rollen mit elliptischen Querschnitt. Dies ist aus Abb. 2 deutlich ersichtlich. Die Rollen 3 sind durch Stege 4 miteinander verbunden. Bei relativen Verdrehvorgängen zwischen der Außenhülse 2 und der inneren Hülse 1 erfolgt ein Abrollen ohne Reibung, so daß entsprechende Rückstellkräfte auftreten. Die besondere Gestaltung macht einenstarken Verdrehwinkel möglich, ohne daß der Rollvorgang in einen Gleitvorgang übergeht. Die Stirnseiten der Rollen 3 gehen in äußere Ringwülste 5 und 6 über. Diese besitzen je eine Ringrippe 7 und 8, die unter Vorspannung auf der inneren Hülse 1 aufsitzen. Winkelverstellungen zwischen der Hülse 1 und der Hülse 2 sind möglich, ohne daß dabei die Ringrippen 7 und 8 in Folge einer Vor spannung abheben.According to Fig. 1 lies between an inner sleeve t and an outer one Sleeve 2 a rubber insert 3. The insert 3 consists of rollers with an elliptical cross-section. This can be clearly seen from Fig. 2. The rollers 3 are connected to one another by webs 4 tied together. In the case of relative twisting processes between the outer sleeve 2 and the inner one Sleeve 1 unrolls without friction, so that corresponding restoring forces appear. The special design makes a strong twist angle possible without that the rolling process changes into a sliding process. The end faces of the rollers 3 go into outer annular beads 5 and 6. These each have an annular rib 7 and 8, which sit on the inner sleeve 1 under pretension. Angular adjustments between the sleeve 1 and the sleeve 2 are possible without the annular ribs 7 and 8 take off as a result of a preload.

An den Kanten 9 der äußeren Hülse 2 weist die Gummieinlage flache Ringnuten 10 auf. Hierdurch wird Raum für die Gummiverdrängung geschaffen. Außerdem wird die mögliche Reibung an der Kante 9 deutlich vermindert. Die im unverformten Zustand radial ausgerichtete Ringfläche 12 dient der verbesserten Anpassung an eventuelle Stoßbelastungen.At the edges 9 of the outer sleeve 2, the rubber insert is flat Ring grooves 10 on. This creates space for the rubber displacement. aside from that the possible friction on the edge 9 is significantly reduced. The in the undeformed State of radially aligned ring surface 12 is used for improved adaptation to possible Shock loads.
