Description
VORRICHTUNG ZUM VERBINDEN UND JUSTIEREN VON ZWEI BAUTEILEN UND VERFAHREN. DEVICE FOR CONNECTING AND ADJUSTING TWO COMPONENTS AND METHODS.
Die Erfindung bezieht sich auf eine Vorrichtung zum Verbinden und Justieren von zwei Bauteilen mit einem äußeren Lagerkörper und einem inneren Lagerkörper mit jeweils einer koaxialen Mittelachse, wobei der äußere Lagerkörper an einem ersten Bauteil und der innere Lagerkörper an einem zweiten Bauteil befestigbar ist. Der äußere Lagerkörper weist eine zumindest teilweise kegel- förmige, konzentrisch zur Mittelachse angeordnete innere Mantelfläche und ei- ne zumindest teilweise zylindrische, konzentrisch zur Mittelachse angeordnete äußere Mantelfläche auf. Der innere Lagerkörper weist eine zumindest teilweise kegelförmige, konzentrisch zur Mittelachse angeordnete äußere Mantelfläche auf, wobei der innere Lagerkörper zumindest teilweise in den äußeren Lager- körper eingesteckt mit seiner äußeren Mantelfläche an der inneren Mantelfläche des äußeren Lagerkörpers anliegt. The invention relates to a device for connecting and adjusting two components with an outer bearing body and an inner bearing body, each having a coaxial center axis, wherein the outer bearing body is attachable to a first component and the inner bearing body to a second component. The outer bearing body has an at least partially conical inner circumferential surface arranged concentrically to the central axis and an at least partially cylindrical outer circumferential surface arranged concentrically to the central axis. The inner bearing body has an at least partially conical, arranged concentrically to the central axis outer lateral surface, wherein the inner bearing body inserted at least partially inserted into the outer bearing body with its outer surface on the inner circumferential surface of the outer bearing body.
Es ist bereits eine Vorrichtung zum Verbinden und Justieren von zwei Bauteilen mit einem äußeren Lagerkörper und einem inneren Lagerkörper mit jeweils einer koaxialen Mittelachse aus der US 6,712,544 B2 bekannt. Zur Justierung in axialer Richtung weist der äußere Lagerkörper eine Riffelung auf, die beim Spreizen in die Buchse eingreift. Hierzu wird der Bolzen in ein Gewinde im inne- ren Lagerkörper eingedreht. There is already a device for connecting and adjusting two components with an outer bearing body and an inner bearing body, each having a coaxial center axis known from US 6,712,544 B2. For adjustment in the axial direction, the outer bearing body has a corrugation, which engages in spreading in the bushing. For this purpose, the bolt is screwed into a thread in the inner bearing body.
Ferner beschreibt die DE 10 2016 213 225 A1 eine Schaltungskomponente mit koaxial angeordneten Kontakthülsen mit kegelförmigen Mantelflächen und einer zentralen Bohrung. Furthermore, DE 10 2016 213 225 A1 describes a circuit component with coaxially arranged contact sleeves with conical lateral surfaces and a central bore.
Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung zum Verbinden und Justieren derart auszubilden und anzuordnen, dass eine vielfältige Justierung und gleichzeitig eine verbesserte Befestigung in axialer Richtung und gleichzei- tig in sämtlichen Richtungen rechtwinklig zu der axialen Richtung möglich sind. The invention has for its object to form a device for connecting and adjusting in such a way and to arrange that a diverse adjustment and at the same time an improved attachment in the axial direction and at the same time in all directions perpendicular to the axial direction are possible.
Gelöst wird die Aufgabe erfindungsgemäß dadurch, dass der innere Lagerkör- per eine Bohrung oder ein Langloch aufweist, wobei die Bohrung exzentrisch zur Mittelachse positioniert ist und das Langloch vom Zentrum des inneren La- gerkörpers in radialer Richtung zur Mittelachse nach außen verläuft. Durch ein Langloch oder ein exzentrisches Loch kann die Drehachse des inneren Lager- körpers relativ zur Mittelachse versetzt werden, sodass durch Drehen des inne- ren Lagerkörpers oder beider Lagerkörper gleichzeitig um die Mittelachse eine Verschiebung beider Lagerkörper in radialer Richtung zur Mittelachse erfolgt. Dadurch, dass der äußere Lagerkörper relativ zum ersten Bauteil in axialer Richtung zur Mittelachse verschiebbar und festsetzbar ist, lässt sich der Lager- körper in axialer Richtung justieren. Die axiale Justierung erfolgt allein über ei- nen Reibschluss zwischen dem ersten Bauteil und der Vorrichtung. Das bedeu- tet eine Justierung ohne ein Gewinde oder weiterer Distanzstücke. The object is achieved according to the invention in that the inner bearing body has a bore or a slot, wherein the bore is positioned eccentrically to the central axis and the slot from the center of the inner La- Gerkörpers in the radial direction to the central axis extends to the outside. By a slot or an eccentric hole, the axis of rotation of the inner bearing body can be offset relative to the central axis, so that simultaneously by rotating the inner bearing body or both bearing body about the central axis of a displacement of the two bearing body in the radial direction to the central axis. The fact that the outer bearing body is displaceable relative to the first component in the axial direction to the central axis and fixable, the bearing body can be adjusted in the axial direction. The axial adjustment takes place solely via a friction fit between the first component and the device. This means an adjustment without a thread or other spacers.
Vorteilhaft kann es hierzu auch sein, wenn eine Buchse vorgesehen ist, in die der äußere Lagerkörper eingesteckt, mit seiner äußeren Mantelfläche zumin- dest teilweise anliegt. Die Buchse dient als Verbindung des äußeren Lagerkör- pers mit einem weiteren Bauteil, welches es zu Justieren gilt. It can also be advantageous for this purpose if a bushing is provided into which the outer bearing body is inserted, at least partially abutting its outer circumferential surface. The bush serves as a connection of the outer bearing body with another component which is to be adjusted.
Ferner kann es vorteilhaft sein, wenn der äußere Lagerkörper und der innere Lagerkörper zumindest teilweise aus einem elastischen Kunststoff und/oder aus Metall und/oder aus Gummi gebildet sind. Elastische Materialien ermöglich neben einer besseren reibschlüssigen Verbindung zwischen den beiden Lager- körpern zudem mit der Befestigung der zu justierenden Bauteile eine Dämpfung von Vibrationen, die von einem auf das andere Bauteil übertragen werden. Furthermore, it may be advantageous if the outer bearing body and the inner bearing body are at least partially made of an elastic plastic and / or metal and / or rubber. In addition to a better frictional connection between the two bearing bodies, elastic materials also make it possible, with the fastening of the components to be adjusted, to damp vibrations which are transmitted from one to the other component.
Vorteilhaft kann es auch sein, wenn ein erstes Bauteil vorgesehen ist und die Buchse an dem ersten Bauteil befestigt oder durch das erste Bauteil gebildet ist. Die Buchse ermöglicht eine Verschiebung des inneren Lagerkörpers in Richtung der Mittelachse, sodass zusammen mit der vorstehend beschriebenen koaxialen Geometrie eine Justierung in alle drei Raumrichtungen möglich ist. Eine Kombination der Vorrichtung zum Justieren mit zumindest einem der beiden zu justierenden Bauteile stellt ein Modul zur Verfügung, das in ein vorhandenes Befestigungskonzept integriert werden kann. It can also be advantageous if a first component is provided and the socket is fastened to the first component or formed by the first component. The bushing allows a displacement of the inner bearing body in the direction of the central axis, so that an adjustment in all three spatial directions is possible together with the coaxial geometry described above. A combination of the device for adjusting with at least one of the two components to be adjusted provides a module that can be integrated into an existing fastening concept.
Dabei kann es vorteilhafterweise vorgesehen sein, dass ein zweites Bauteil mit einer Öffnung vorgesehen ist und die Vorrichtung V in die Öffnung eingeführt ist. Dadurch wird das Modul um das zweite zu justierende Bauteil ergänzt, das innerhalb der Öffnung in axialer Richtung justierbar ist. Zudem kann die Vorrich- tung über die Öffnung am zweiten Bauteil befestigt werden. It may advantageously be provided that a second component is provided with an opening and the device V is inserted into the opening is. As a result, the module is supplemented by the second component to be adjusted, which is adjustable within the opening in the axial direction. In addition, the device can be fastened via the opening on the second component.
Besonders vorteilhaft ist es, dass ein Bolzen in dem Langloch angeordnet ist und der Bolzen den inneren Lagerkörper mittel- oder unmittelbar mit dem zwei- ten Bauteil verbindet. Der Bolzen kann durch das Langloch relativ zum inneren Lagerkörper gegenüber der Mittelachse in radialer Richtung versetzt werden und dient dabei als Drehachse für den inneren Lagerkörper 2. Der Bolzen kann auch als Stift ohne ein Gewinde oder als sonstiges Element zur Lagerung und Befestigung der beiden Lagerkörper und zur Bildung einer zur Mittelachse zent- rischen oder exzentrischen Drehachse ausgeführt sein. Ein solcher Stift kann an das zweite Bauteil angeschweißt oder über eine Klammer in axialer Richtung der Mittelachse relativ zum inneren Lagerkörper und/oder relativ zum zweiten Bauteil fixiert sein. It is particularly advantageous that a bolt is arranged in the slot and the bolt connects the inner bearing body directly or indirectly with the second component. The bolt can be offset by the slot relative to the inner bearing body relative to the central axis in the radial direction and serves as a rotation axis for the inner bearing body 2. The bolt can also be used as a pin without a thread or as an other element for mounting and attachment of the two bearing body and be designed to form a central axis to the central or eccentric axis of rotation. Such a pin can be welded to the second component or fixed by a clamp in the axial direction of the central axis relative to the inner bearing body and / or relative to the second component.
Von besonderer Bedeutung kann für die vorliegende Erfindung sein, wenn der Bolzen einen Kopf und einen Schaft mit einem Außengewinde aufweist, wobei das Außengewinde in ein Gewinde in der Öffnung oder in eine Mutter einge- dreht und durch das Festdrehen des Bolzens der innere Lagerkörper relativ zu dem äußeren Lagerkörper verschiebbar ist. Aufgrund der kegelförmigen Gestaltung wird durch das Ineinanderschieben der beiden Lagerkörper in Richtung der Mittelachse erreicht, dass der äußere Lagerkörper in seinem äußeren Durch- messer vergrößert wird und in der Buchse zumindest reibschlüssig festsetzbar ist. Durch das Festdrehen des Bolzens beispielsweise wird der äußere Lager- körper reib- und/oder formschlüssig an der Innenfläche der Buchse in axialer Richtung und in radialer Richtung sowie in Umfangsrichtung zur Mittelachse fi- xiert. Zudem wird durch das Festdrehen des Bolzens der innere Lagerkörper reib- und/oder formschlüssig in Umfangsrichtung zur Mittelachse sowie in Rich- tung der Mittelachse im äußeren Lagerkörper fixiert. Of particular importance may be for the present invention, when the bolt has a head and a shaft with an external thread, wherein the external thread screwed into a thread in the opening or in a nut and by tightening the bolt, the inner bearing body relative to the outer bearing body is displaceable. Due to the conical design is achieved by the telescoping of the two bearing bodies in the direction of the central axis, that the outer bearing body is increased in its outer diameter and in the socket at least frictionally festsetzbar. As a result of the tightening of the bolt, for example, the outer bearing body is fixed in a frictional and / or form-fitting manner on the inner surface of the bush in the axial direction and in the radial direction and in the circumferential direction relative to the central axis. In addition, the inner bearing body is fixed in a frictional and / or positive locking manner in the circumferential direction to the central axis as well as in the direction of the central axis in the outer bearing body by the tightening of the bolt.
Im Zusammenhang mit der erfindungsgemäßen Ausbildung und Anordnung kann es von Vorteil sein, wenn der äußere Lagerkörper eine Dehnungsfuge aufweist. Dadurch ist eine Änderung seines Durchmessers auch bei weniger elastischem Material möglich. In connection with the design and arrangement according to the invention, it may be advantageous if the outer bearing body an expansion joint having. As a result, a change in its diameter is possible even with less elastic material.
Vorteilhaft kann es ferner sein, wenn das erste Bauteil und das zweite Bauteil als Klammer oder als Verbindungselement zum Befestigen eines Konverters oder Schalldämpfers einer Abgasanlage oder eines sonstigen Elements einer Abgasanlage ausgebildet sind. It can also be advantageous if the first component and the second component are designed as a clamp or as a connecting element for fastening a converter or silencer of an exhaust system or of another element of an exhaust system.
Außerdem kann ein System vorteilhaft sein, das aus einer Vorrichtung wie vor- stehend beschrieben und einer Abgasanlage einer Verbrennungskraftmaschine oder zumindest einem Konverter oder Schalldämpfer einer Abgasanlage besteht, wobei eines der Bauteile an dem Konverter oder an dem Schalldämpfer oder an der Abgasanlage befestigt ist. Durch das Befestigen des anderen Bau- teils an beispielsweise einer Karosserie eines Fahrzeugs kann durch die Vorrichtung der Konverter oder Schalldämpfer relativ zur Karosserie justiert wer- den. In addition, a system may be advantageous which consists of a device as described above and an exhaust system of an internal combustion engine or at least one converter or muffler of an exhaust system, wherein one of the components is attached to the converter or to the muffler or to the exhaust system. By attaching the other component to, for example, a body of a vehicle, the converter or silencer can be adjusted relative to the body by the device.
Ferner kann ein Verfahren zum Justieren und Befestigen von zwei Bauteilen relativ zueinander vorteilhaft sein, bei dem mit einer vorstehend beschriebenen Vorrichtung und einer Buchse an dem ersten Bauteil sowie einem in dem Langloch angeordneten Bolzen mit einem Kopf und einem Außengewinde fol gende Verfahrensschritte durchgeführt werden: a) Positionieren des inneren Lagerkörpers in dem äußeren Lagerkörper und des äußeren Lagerkörpers in der Buchse; b) Ansetzen des Bolzens durch mittel- oder unmittelbares Verschrauben mit dem zweiten Bauteil; c) Justieren der beiden Bauteile in einer radialen Richtung zur Mittelachse durch Verschieben des Bolzens in radialer Richtung relativ zum inneren Lager- körper und durch Drehen des inneren Lagerkörpers relativ zum zweiten Bauteil mit der Folge einer relativen Verschiebung der beiden Bauteile zueinander in radialer Richtung zur Mittelachse; d) Justieren der beiden Bauteile, in axialer Richtung zur Mittelachse durch Verschieben der Buchse relativ zum äußeren Lagerkörper in radialer Richtung zu Mittelachse; e) Festdrehen des Bolzens, bis der innere Lagerkörper ausreichend weit in den äußeren Lagerkörper hinein verschoben und der äußere Lagerkörper ausreichend in seinem äußeren Durchmesser vergrößert wird, sodass der innere Lagerkörper und der äußere Lagerkörper reibschlüssig fixiert sind. Further, a method for adjusting and fixing two components relative to each other may be advantageous, in which the fol lowing method steps are performed with a device described above and a socket on the first component and a bolt arranged in the slot with a head and an external thread: a ) Positioning the inner bearing body in the outer bearing body and the outer bearing body in the socket; b) attaching the bolt by means of direct or indirect screwing with the second component; c) adjusting the two components in a radial direction to the central axis by moving the bolt in the radial direction relative to the inner bearing body and by rotating the inner bearing body relative to the second component with the result of a relative displacement of the two components to each other in the radial direction to the central axis ; d) adjusting the two components, in the axial direction to the central axis by displacing the bushing relative to the outer bearing body in the radial direction to the central axis; e) tightening of the bolt until the inner bearing body moved sufficiently far into the outer bearing body and the outer bearing body is sufficiently increased in its outer diameter, so that the inner bearing body and the outer bearing body are frictionally fixed.
Durch das relative Verdrehen des äußeren Lagerkörpers zum inneren Lagerkörper um die Mittelachse kann je nach Drehwinkel zwischen 0° und 360° um die Drehachse eine Justierung der beiden Bauteile in jeder beliebigen Richtung radial zur Mittelachse um ein Maß 8, 9 erfolgen, das vom Abstand der Drehach- se von der Mittelachse abhängig ist. Das Verschieben des inneren Lagerkör- pers relativ zu der Buchse in axialer Richtung zur Mittelachse kann in einer Richtung Z das Maß 10 zum Justieren der beiden Bauteile relativ zueinander eingestellt werden. Due to the relative rotation of the outer bearing body to the inner bearing body about the central axis, depending on the angle of rotation between 0 ° and 360 ° about the axis of rotation an adjustment of the two components in any direction radially to the central axis by a dimension 8, 9 done, the distance from the Rotary axis is dependent on the central axis.

Mit der Vorrichtung V ist ein erstes Bauteil 5 an einem zweiten Bauteil 6 gela- gert und das erste Bauteil 5 kann mithilfe der Vorrichtung V relativ zum zweiten Bauteil 6 justiert und am zweiten Bauteil 6 befestigt werden. Die Vorrichtung V umfasst als grundlegende Lösung der Aufgabe zwei Lagerkörper 1 , 2, die zu- mindest teilweise aus einem elastischen Kunststoff hergestellt sind und die ko- axial zu einer gemeinsamen Mittelachse M ineinander gesteckt sind, sich relativ zueinander drehen lassen und die eine im Abstand zur Mittelachse M variable exzentrische Lagerung eines Bolzens 4 im inneren Lagerkörper 2 erlauben. Die Mittelachse M ist in einer Z-Richtung ausgerichtet. FIG. 4 shows an exploded view of a device according to FIGS. 2a, 2b with a simplified representation of a converter and a body part. Figure 1 shows an illustration of a device V in a sectional view. With the device V, a first component 5 is mounted on a second component 6 and the first component 5 can be adjusted relative to the second component 6 by means of the device V and fastened to the second component 6. As a basic solution to the problem, the device V comprises two bearing bodies 1, 2, which are at least partially made of an elastic plastic and which are coaxially inserted into a common center axis M, can rotate relative to each other, and one at a distance allow for the central axis M variable eccentric mounting of a bolt 4 in the inner bearing body 2. The center axis M is aligned in a Z direction.
Der äußere Lagerkörper 1 ist symmetrisch zu der Mittelachse M und besitzt ei- ne zylindrische äußere Mantelfläche 12 sowie eine kegelförmige innere Mantel- fläche 11. Der inneren Lagerkörper 2 besitzt eine zur inneren Mantelfläche 11 parallele äußere kegelförmige äußere Mantelfläche 21 , mit der er reibschlüssig mit dem äußeren Lagerkörper 1 in Kontakt steht. Der Winkel a der Kegel variiert zwischen 2° und 16°. Der innere Lagerkörper 2 weist zudem ein Langloch 22 auf, das sich ausgehend von einer zu seiner Mittelachse M koaxialen Bohrung in radialer Richtung erstreckt wie es anhand der fehlenden Schraffur in Figur 1 zu erkennen ist. In Figur 2 ist das Langloch 22 in einer Frontansicht dargestellt. The outer bearing body 1 is symmetrical to the central axis M and has a cylindrical outer lateral surface 12 and a conical inner lateral surface 11. The inner bearing body 2 has an inner conical surface 11 parallel outer conical outer lateral surface 21, with which it frictionally with the outer bearing body 1 is in contact. The angle a of the cones varies between 2 ° and 16 °. The inner bearing body 2 also has a slot 22, which extends from a coaxial to its central axis M bore in the radial direction as can be seen from the missing hatching in Figure 1. In Figure 2, the slot 22 is shown in a front view.
Durch einen Bolzen 4, der durch den inneren Lagerkörper 2 hindurch gesteckt ist, kann der innere Lagerkörper 2 um den Bolzen 4 herum um eine Drehach- se D gedreht werden. Je nachdem, in welcher radialen Position der Bolzen 4 im Langloch 22 positioniert ist, variiert der Abstand zwischen der Mittelachse M und der Drehachse D des inneren Lagerkörpers 2. By a bolt 4, which is inserted through the inner bearing body 2, the inner bearing body 2 can be rotated around the bolt 4 around a rotation axis D. Depending on the radial position in which the bolt 4 is positioned in the slot 22, the distance between the central axis M and the axis of rotation D of the inner bearing body 2 varies.
In einer für die Montage erweiterten Ausführungsform ist der äußere Lagerkörper 1 gemäß den Figuren 1 , 2a und 2b in einer Buchse 3 derart gelagert, dass der äußere Lagerkörper 1 in axialer Richtung der Mittelachse M und somit in Z- Richtung in der Buchse 3 verschoben werden kann. In den beiden in den Figu- ren 2a und 2b dargestellten unterschiedlichen Positionen wird deutlich, dass der äußere Lagerkörper 1 durch den Einsatz der Buchse 3 in Z-Richtung um ein Maß 10 relativ zu der Buchse 3 und in der Buchse 3 verschoben werden kann. Dabei ist die Buchse 3 an einem ersten Bauteil 5 gelagert, das zum Justieren eines am ersten Bauteil 5 befestigten Konverters 51 über die Vorrichtung V und das zweite Bauteil 6 beispielsweise an einer Karosserie 62 befestigt werden kann. Ferner wird der äußere Lagerkörper 1 mittelbar über den inneren Lager- körper 2 beim Befestigen in Richtung Z an das zweite Bauteil 6 gedrückt. Durch den zwischen dem äußeren Lagerkörper 1 und dem zweiten Bauteil 6 erzeugten Druck entsteht eine Reibung, die das Verdrehen des äußeren Lagerkörpers 1 um die Mittelachse M relativ zum zweiten Bauteil 6 verhindern kann. Die zu- sätzlich zwischen dem äußeren Lagerkörper 1 und dem inneren Lagerkörper 2 und zwischen dem Bolzen 4 und dem inneren Lagerkörper 2 beim Befestigen entstehende Reibung um die Mittelachse M verhindert eine relative Drehung des ersten Bauteils 5 relativ zum zweiten Bauteil 6 um die Mittelachse M. Durch eine geeignete Wahl der jeweiligen Materialien oder der Rauigkeit der jeweili- gen Oberflächen oder durch den Einsatz von weiteren Scheiben oder Hülsen kann das Maß der Reibung um die Mittelachse M beeinflusst werden. In an embodiment which is expanded for mounting, the outer bearing body 1 according to FIGS. 1, 2 a and 2 b is mounted in a bush 3 such that the outer bearing body 1 is displaced in the axial direction of the center axis M and thus in the Z direction in the bush 3 can. In the two different positions shown in FIGS. 2a and 2b, it is clear that the outer bearing body 1 can be displaced by the use of the bushing 3 in the Z direction by a dimension 10 relative to the bushing 3 and in the bushing 3. In this case, the bushing 3 is mounted on a first component 5, which can be fastened for adjusting a converter 51 fastened to the first component 5 via the device V and the second component 6, for example, to a body 62. Furthermore, the outer bearing body 1 is pressed indirectly via the inner bearing body 2 when fastening in the direction Z to the second component 6. By the pressure generated between the outer bearing body 1 and the second component 6 creates a friction that can prevent the rotation of the outer bearing body 1 about the central axis M relative to the second component 6. The additional friction between the outer bearing body 1 and the inner bearing body 2 and between the pin 4 and the inner bearing body 2 during mounting around the center axis M prevents relative rotation of the first member 5 relative to the second member 6 about the central axis M. By a suitable choice of the respective materials or the roughness of the respective surfaces or by the use of further discs or sleeves, the degree of friction about the central axis M can be influenced.
Der innere Lagerkörper 2 ist in dieser Ausführungsform über den Bolzen 4 an einem zweiten Bauteil 6 gelagert. Hierzu weist der Bolzen 4 einen Kopf 41 auf, mit dem er am inneren Lagerkörper 2 anschlägt. Der Schaft 42 des Bolzens 4 weist ein Außengewinde 43 auf, mit dem er in eine Mutter 44 eingedreht ist, die am zweiten Bauteil 6 über eine Schweißnaht 7 befestigt ist. Durch das Festdre- hen des Bolzens 4 wird der innere Lagerkörper 2 in den äußeren Lagerkörper 1 hinein gedrückt und gleichzeitig der äußere Lagerkörper 1 aufgrund der Kegel- formen in seinem Durchmesser vergrößert. Dadurch entsteht eine reibschlüssi- ge Verbindung zwischen dem inneren Lagerkörper 2 und dem äußeren Lager- körper 1 sowie zwischen dem äußeren Lagerkörper 1 und der Buchse 3. Auch die für die Bewegung in axialer Richtung maßgeblichen Flächen können durch eine geeignete Stoffauswahl oder um die Oberflächenrauigkeit variiert werden, um die Reibung zu beeinflussen. The inner bearing body 2 is mounted in this embodiment on the bolt 4 on a second component 6. For this purpose, the bolt 4 has a head 41 with which it abuts the inner bearing body 2. The shaft 42 of the bolt 4 has an external thread 43 with which it is screwed into a nut 44, which is fastened to the second component 6 via a weld 7. Due to the tightening of the bolt 4, the inner bearing body 2 is pressed into the outer bearing body 1 and at the same time the outer bearing body 1 is enlarged in diameter due to the conical shapes. This results in a frictional connection between the inner bearing body 2 and the outer bearing body 1 and between the outer bearing body 1 and the bushing 3. The surfaces which are decisive for the movement in the axial direction can also be varied by a suitable material selection or by the surface roughness be used to influence the friction.
In den Figuren 3a bis 3d sind vier verschiedene Positionen des inneren Lager- körpers 2 dargestellt, durch die der innere Lagerkörper 2 um ein Maß 9 in Y- Richtung und um ein Maß 8 in X-Richtung durch Verdrehen des inneren Lagerkörpers 2 verschoben wird. Grundsätzlich ist es jedoch möglich, den inneren Lagerkörper 2 auch in jede beliebige Richtung zwischen den Richtungen X und Y zu bewegen, weil der innere Lagerkörper 2 stufenlos bis zu 360 verdrehbar gelagert ist. In FIGS. 3a to 3d, four different positions of the inner bearing body 2 are shown, by means of which the inner bearing body 2 is displaced by a dimension 9 in the Y direction and by a dimension 8 in the X direction by rotation of the inner bearing body 2. In principle, however, it is possible the inner Bearing body 2 to move in any direction between the directions X and Y, because the inner bearing body 2 is continuously rotatably mounted up to 360.
In einer Modulbauweise sind die beiden Bauteile 5, 6 Teil der Vorrichtung V und werden wie in Figur 4 dargestellt einerseits an einer Karosserie 62 eines Fahrzeugs und andererseits an einem Konverter 51 einer Abgasanlage befestigt, um den Konverter 51 relativ zur Karosserie 62 zu justieren. Dabei ist das System bestehend aus einer Abgasanlage oder zumindest aus einem Konverter 51 und einer Vorrichtung V sehr vorteilhaft. Abgasanlagen von Fahrzeugen bestehen aus Krümmern, Abgasrohren und mehreren Konvertern wie Oxidationskatalysa- toren, SCR-Katalysatoren und Partikelfiltern, sodass insgesamt eine relativ gro- ße Toleranz für die Montage erforderlich ist, weil Abweichungen von in der Summe der beschriebenen Bauteile mehreren Millimetern üblich sind. Diese Abweichungen können mit der Vorrichtung V ausgeglichen werden. In a modular design, the two components 5, 6 are part of the device V and as shown in Figure 4 on the one hand to a body 62 of a vehicle and on the other hand attached to a converter 51 an exhaust system to adjust the converter 51 relative to the body 62. In this case, the system consisting of an exhaust system or at least a converter 51 and a device V is very advantageous. Exhaust systems of vehicles consist of manifolds, exhaust pipes and several converters such as oxidation catalysts, SCR catalytic converters and particulate filters, so that overall a relatively large tolerance for the assembly is required because deviations from the sum of the components described are several millimeters common. These deviations can be compensated with the device V.
