Description

Lageranordnung  bearing arrangement
Die Erfindung betrifft eine Lageranordnung zur Lagerung eines Nehmerzylinders am Deckel einer Kupplung, insbesondere für ein Kraftfahrzeug. The invention relates to a bearing arrangement for mounting a slave cylinder on the cover of a clutch, in particular for a motor vehicle.
Kupplungen werden gemäß dem Stand der Technik mit konzentrischen Nehmerzylindern betätigt, die von dem Kupplungsdeckel getragen werden, wobei zwischen Kupplungsdeckel und Nehmerzylinder ein Lager angeordnet ist, um die Kupplung relativ zum Nehmerzylinder verdrehbar zu lagern. Dabei wird der Nehmerzylinder mit einer zylindrischen Außenfläche von dem Lagerinnenring radial innen aufgenommen und der Kupplungsdeckel nimmt mit einer zylindrischen Öffnung den Lageraußenring radial innen auf. Clutches are operated according to the prior art with concentric slave cylinders which are supported by the clutch cover, wherein between the clutch cover and slave cylinder, a bearing is arranged to rotatably support the clutch relative to the slave cylinder. In this case, the slave cylinder is received with a cylindrical outer surface of the bearing inner ring radially inward and the clutch cover takes with a cylindrical opening the bearing outer ring radially inside.
Bei den bekannten Konstruktionen wird der Lageraußenring in die Öffnung des Deckels eingepresst, was zu Problemen hinsichtlich der Lebensdauer des Lagers führt, weil nicht definierte Axial- und Radialkräfte auftreten können, wenn das Lager nicht optimal angeordnet und eingepresst wird. In the known constructions of the bearing outer ring is pressed into the opening of the lid, which leads to problems in terms of life of the bearing, because undefined axial and radial forces can occur when the bearing is not optimally arranged and pressed.
Es ist die Aufgabe der Erfindung, eine Lageranordnung zu schaffen, welche einfach aufgebaut ist und dennoch eine definierte Anordnung und Einpressung aufweist, so dass die Lebensdauer des Lagers erhöht ist gegenüber dem Stand der Technik. It is the object of the invention to provide a bearing assembly, which is simple in construction and yet has a defined arrangement and pressing, so that the life of the bearing is increased over the prior art.
Die Aufgabe der Erfindung wird mit den Merkmalen von Anspruch 1 gelöst. The object of the invention is achieved with the features of claim 1.
Ein Ausführungsbeispiel der Erfindung betrifft eine Lageranordnung zur Lagerung eines Nehmerzylinders am Deckel einer Kupplung, insbesondere für ein Kraftfahrzeug, mit einem konzentrisch zur Drehachse der Kupplung angeordneten Nehmerzylinder, wobei der Nehmerzylinder von dem Kupplungsdeckel der Kupplung getragen ist, wobei zwischen dem Kupplungsdeckel und dem Nehmerzylinder ein Lager angeordnet ist, um die Kupplung relativ zum Nehmerzylinder verdreh-bar zu lagern, wobei der Nehmerzylinder eine zylindrischen Außenfläche aufweist, welche von einem Lagerinnenring des Lagers radial innen aufgenommen ist und der Kupplungsdeckel mit einer zylindrischen Öffnung ausgebildet ist, welche einen Lageraußenring des Lagers radial innen aufnimmt, wobei der Lageraußenring radial außen eine Stufe aufweist und der Kupplungsdeckel radial innen einen L-Förmigen Bereich aufweist mit einem in radialer Richtung verlaufenden ersten Schenkel und mit einem in axialer Richtung verlaufenden zweiten Schenkel, wobei der Kupplungsdeckel mit seinem ersten Schenkel und mit seinem zweiten Schenkel an dem Lageraußenring anliegt. Dadurch wird eine radiale und axiale Zentrierung erreicht, was einen definierten Zustand beim Einpressen des Lagers in die Öffnung des Kupplungsdeckels erlaubt. An embodiment of the invention relates to a bearing assembly for supporting a slave cylinder on the cover of a clutch, in particular for a motor vehicle, arranged with a concentric to the rotational axis of the clutch slave cylinder, wherein the slave cylinder is carried by the clutch cover of the clutch, wherein between the clutch cover and the slave cylinder Bearing is arranged to rotatably support the clutch relative to the slave cylinder, wherein the slave cylinder has a cylindrical outer surface which is received radially inwardly from a bearing inner ring of the bearing and the clutch cover is formed with a cylindrical opening which a bearing outer ring of the bearing radially receives inside, wherein the bearing outer ring radially outwardly has a step and the clutch cover has radially inwardly an L-shaped portion having a radially extending first leg and extending in the axial direction of the second Schen kel, wherein the clutch cover rests with its first leg and with its second leg to the bearing outer ring. This will cause a radial and achieved axial centering, which allows a defined state when pressing the bearing in the opening of the clutch cover.
Dabei ist es vorteilhaft, wenn der zweite Schenkel eine Fase oder eine Aussparung aufweist, so dass nur ein Teilbereich des Schenkels an dem Lageraußenring anliegt. Dadurch kann Luft zwischen den Außenring des Deckellagers und Kupplungsdeckel treten, weil ein Abstand gewährleistet ist. Dadurch wird eine definierte Krafteinleitung in den Lagerring bewirkt. It is advantageous if the second leg has a chamfer or a recess, so that only a portion of the leg rests against the bearing outer ring. As a result, air can enter between the outer ring of the cover bearing and clutch cover, because a distance is ensured. As a result, a defined force is introduced into the bearing ring.
Auch ist es vorteilhaft, wenn der zweite Schenkel über die gesamte Länge des zweiten Schenkels an dem Lageraußenring anliegt. Dadurch kann über die Definition der Länge des zweiten Schenkels die Krafteinleitung in den Lagerring definiert werden. It is also advantageous if the second leg bears against the bearing outer ring over the entire length of the second leg. As a result, the introduction of force into the bearing ring can be defined by defining the length of the second leg.
Auch ist es zweckmäßig, wenn das Lager einen Wälzkörper aufweist mit einer in radialer Richtung ausgerichteten Mittelachse, wobei der Anlagebereich von Lageraußenring und erstem Schenkel auf einer Seite der Mittelachse angeordnet ist, wobei der in axialer Richtung sich erstreckende zweite Schenkel nur auf der Seite der Mittelachse an dem Lageraußenring anliegt, auf welcher auch der Anlagebereich des ersten Schenkels angeordnet ist. Dadurch wird eine definierte Krafteinleitung in den Lagerring bewirkt, die auf einer Seite der Mittelachse liegt. It is also expedient if the bearing has a rolling body with a center axis aligned in the radial direction, wherein the abutment region of the bearing outer ring and the first leg is arranged on one side of the central axis, wherein the second leg extending in the axial direction only on the side of the central axis rests against the bearing outer ring, on which also the contact region of the first leg is arranged. As a result, a defined introduction of force is effected in the bearing ring, which lies on one side of the central axis.
Alternativ ist es auch zweckmäßig, wenn das Lager einen Wälzkörper aufweist mit einer in radialer Richtung ausgerichteten Mittelachse, wobei der Anlagebereich von Lageraußenring und erstem Schenkel auf einer Seite der Mittelachse angeordnet ist, wobei der in axialer Richtung sich erstreckende zweite Schenkel sich bis auf die Seite der Mittelachse erstreckt und an dem Lageraußenring anliegt, welche auf der anderen Seite ist, wie der Anlagebereich des ersten Schenkels. Dadurch werden definierte Krafteinleitungen in den Lagerring bewirkt, die auf beiden Seiten der Mittelachse liegen. Alternatively, it is also expedient if the bearing has a rolling element with a center axis aligned in the radial direction, wherein the abutment region of bearing outer ring and first leg is arranged on one side of the central axis, wherein the second leg extending in the axial direction extends to the side extends the central axis and rests against the bearing outer ring, which is on the other side, as the contact region of the first leg. As a result, defined force discharges are effected in the bearing ring, which lie on both sides of the central axis.
Besonders vorteilhaft ist es, wenn das Lager ein Schrägkugellager ist. It is particularly advantageous if the bearing is an angular contact ball bearing.
Besonders vorteilhaft ist es, wenn der Lagerinnenring eine sich in axialer Richtung It is particularly advantageous if the bearing inner ring is in the axial direction
erstreckende Innenringfläche aufweist, wobei der Nehmerzylinder auf voller axialer Länge dieser Innenringfläche an dieser anliegt. Auch ist es zweckmäßig, wenn der Nehmerzylinder ein in radialer Richtung vorstehendes Anschlagelement aufweist, an welchem sich der Lagerinnering in axialer Richtung abstützt. having extending inner ring surface, wherein the slave cylinder rests on full axial length of this inner ring surface of this. It is also expedient if the slave cylinder has a stop element protruding in the radial direction, on which the bearing inner ring is supported in the axial direction.
Dabei ist es auch zweckmäßig, wenn der Nehmerzylinder mit einer Kolben-Zylindereinheit zur Betätigung einer Kupplung ausgebildet ist. It is also expedient if the slave cylinder is formed with a piston-cylinder unit for actuating a clutch.
Alternativ ist es vorteilhaft, wenn der Nehmerzylinder mit zwei Kolben-Zylindereinheiten zur Betätigung einer Doppelkupplung ausgebildet ist. Alternatively, it is advantageous if the slave cylinder is designed with two piston-cylinder units for actuating a double clutch.
