Abstract
Die Erfindung betrifft eine Lageranordnung für ein Antriebsaggregat (10), insbesondere ein Elektromotor, eines Fahrzeugs, wobei mindestens vier Buchsen (12,13) vorgesehen sind, die das Antriebsaggregat (10) in verschiedenen Raumrichtung abstützen. Um eine kostengünstige Lagerung ohne Anschläge zu ermöglichen, sind die Buchsen (12,13) auf jeder Seite (18, 19) des Antriebaggregats (10) mit Abstand zueinander angeordnet, wobei die benachbarten und gegenüber liegenden Buchsen (12a, 13b; 12b, 13a) jeweils in verschiedene Raumrichtungen (X, Y) wirken.The invention relates to a bearing arrangement for a drive unit (10), in particular an electric motor, of a vehicle, at least four sockets (12, 13) being provided which support the drive unit (10) in different spatial directions. In order to enable inexpensive storage without stops, the sockets (12, 13) on each side (18, 19) of the drive unit (10) are arranged at a distance from one another, the adjacent and opposite sockets (12a, 13b; 12b, 13a ) each act in different spatial directions (X, Y).
Description
Die Erfindung betrifft eine Lageranordnung für ein Antriebsaggregat, insbesondere einen Elektromotor eines Fahrzeuges, wobei mindestens vier Buchsen vorgesehen sind, die das Antriebsaggregat in verschiedene Raumrichtungen abstützen.The invention relates to a bearing arrangement for a drive unit, in particular an electric motor of a vehicle, with at least four bushes being provided which support the drive unit in different spatial directions.
Vierpunktlagerungen für Antriebsaggregate mittels Buchsen sind bekannt. Antriebsaggregate, insbesondere Elektromotoren, werden meist mittels Buchsen gelagert. Die Anordnung der gegenüberliegenden Buchsen weist dabei die gleiche Wirkrichtung auf. Da eine einfache Buchse bestehend aus Kern, Tragfederelastomer und Außenrohr, konzeptbedingt nur in radialer Richtung einen Festanschlag aufweist, muss die Bewegung bei obiger paarweiser Anordnung in axiale Richtung mit zusätzlichen internen oder externen Anschlägen begrenzt werden, insbesondere bei einem Unfall.Four-point bearings for drive units by means of sockets are known. Drive units, especially electric motors, are usually supported by means of sockets. The arrangement of the opposite bushings has the same direction of action. Since a simple bushing consisting of core, suspension spring elastomer and outer tube only has a fixed stop in the radial direction due to the concept, the movement in the above paired arrangement in the axial direction must be limited with additional internal or external stops, especially in the event of an accident.
Der Erfindung liegt die Aufgabe zugrunde, eine kostengünstige Lagerung eines Antriebsaggregats eines Fahrzeugs ohne zusätzliche Anschläge zu ermöglichen.The invention is based on the object of enabling an inexpensive mounting of a drive unit of a vehicle without additional stops.
Zur Lösung dieser Aufgabe wird bei einer Lageranordnung der eingangs genannten Art vorgeschlagen, dass die Buchsen auf jeder Seite des Antriebsaggregats mit Abstand zueinander angeordnet sind, wobei die benachbarten und gegenüber liegenden Buchsen jeweils in verschiedenen Raumrichtungen wirken.To solve this problem, it is proposed in a bearing arrangement of the type mentioned that the bushings are arranged at a distance from one another on each side of the drive unit, the adjacent and opposite bushings each acting in different spatial directions.
Die diagonal gegenüber liegenden Buchsen weisen jeweils die gleiche Wirkrichtung auf und die gegenüber liegenden Buchsen weisen jeweils eine unterschiedliche Wirkrichtung auf. Somit wird es ermöglicht, dass das Antriebsaggregat in alle drei Raumrichtungen mit einfachen elastischen Buchsen abgestützt wird, ohne komplizierte oder zusätzliche Anschläge zu benötigen.The diagonally opposite sockets each have the same direction of action and the opposite sockets each have a different direction of action. This makes it possible for the drive unit to be supported in all three spatial directions with simple elastic bushings without the need for complicated or additional stops.
Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.Advantageous embodiments of the invention are the subject of the subclaims.
Bei einer vorteilhaften Ausgestaltung sind die benachbarten und gegenüber liegenden Buchsen (
Vorteilhaft sind die Buchsen jeweils einerseits am Antriebsaggregat und andererseits an einem Fahrzeugteil, insbesondere der Fahrzeugkarosserie, befestigt.The sockets are advantageously fastened on the one hand to the drive unit and on the other hand to a vehicle part, in particular the vehicle body.
Vorteilhaft weisen die Buchsen eine Innenhülse auf, die über einen Elastomerkörper mit einer Außenhülse verbunden ist. Derartige Buchsen sind kostengünstig herstellbar.The bushings advantageously have an inner sleeve which is connected to an outer sleeve via an elastomer body. Such sockets are inexpensive to manufacture.
Vorteilhaft sind die Buchsen identisch ausgebildet. Hierdurch ergibt sich eine kostengünstige Herstellung der Lageranordnung.The sockets are advantageously designed identically. This results in a cost-effective production of the bearing arrangement.
Nachfolgend wird die Erfindung anhand eines Ausführungsbeispiels näher erläutert, das in schematischer Weise in den beigefügten Zeichnungen dargestellt ist.The invention is explained in more detail below with reference to an exemplary embodiment which is shown schematically in the accompanying drawings.
