AUFGABE DER ERFINDUNGTASK OF THE INVENTION
Der Erfindung liegt die Aufgabe zugrunde, ein Lager mit veränderbarer Steifigkeit, das insbesondere als Aggregatelager für ein Kraftfahrzeug geeignet ist und das die Merkmale des Oberbegriffs des Patentanspruchs 1 aufweist, aufzuzeigen, bei dem das von einer Spule hervorgerufene Magnetfeld möglichst vollständig genutzt wird und den Federkörper aus dem Elastomerwerkstoff mit den eingebetteten magnetischen Partikeln möglichst vollständig durchsetzt.Of the Invention is based on the object, a warehouse with changeable Stiffness, especially as an assembly warehouse for a motor vehicle is suitable and that the features of the preamble of the claim 1, to show, in which caused by a coil Magnetic field as possible Completely is used and the spring body of the elastomeric material with the embedded magnetic particles preferably completely interspersed.
LÖSUNGSOLUTION
Die Aufgabe der Erfindung wird durch ein Lager mit den Merkmalen des Patentanspruchs 1 gelöst. Bevorzugte Ausführungsbeispiele des neuen Lagers sind in den Unteransprüchen 2 bis 11 definiert.The The object of the invention is achieved by a bearing with the features of Patent claim 1 solved. Preferred embodiments the new bearing are defined in the subclaims 2 to 11.
BESCHREIBUNG DER ERFINDUNGDESCRIPTION THE INVENTION
Bei dem neuen Lager liegt der Federkörper vor der Spule, so dass die durch das Innere der Spule verlaufenden Feldlinien durch den Federkörper hindurch treten müssen. Vorzugsweise ist der Federkörper dabei mittig vor der Spule angeordnete, so dass eine geradlinig verlängerte Spulenachse der Spule mittig durch den Federkörper hindurch verläuft. Das von der Spule hervorgerufene Magnetfeld kann dort, wo es aus dem inneren der Spule austritt, in seinem Durchmesser sowohl durch den Verlauf der Spule selbst als auch durch einen Kern der Spule so variiert werden, dass der gesamte Elastomerwerkstoff des Formkörpers von magnetischem Fluss des Magnetfelds durchsetzt ist.at the new bearing is the spring body the coil so that the field lines passing through the interior of the coil through the spring body have to step through. Preferably, the spring body while being centered in front of the spool, leaving a straight line extended Coil axis of the coil passes centrally through the spring body. That from The coil induced magnetic field can be where it is from the inside the coil exits, in its diameter both through the course the coil itself as well as being varied by a core of the coil so that the entire elastomeric material of the molding of magnetic flux the magnetic field is interspersed.
Vorzugsweise weist die Spule einen Kern aus magnetischem Material auf, der direkt an oder sogar in dem Federkörper endet. Dieser Kern ist weiter vorzugsweise ein Fortsatz eines Befestigungsbolzens eines der Befestigungselemente, um den herum die Spule gewickelt ist. In der Regel wird die Spule aber nicht direkt auf diesen Befestigungsbolzen gewickelt sein sondern auf einem eigenen Spulenträger sitzen.Preferably, the coil has a core of magnetic material, which ends directly at or even in the spring body. This core is further preferably an extension of a fastening bolt of one of the fastening elements, around which the coil is wound. As a rule, however, the coil will not be wound directly onto this fastening bolt but will sit on its own coil carrier.
Die Spule kann auf ihrer dem Formkörper abgekehrten Seite an eine magnetische Rückflussplatte angrenzen, durch die hindurch die Feldlinien des Magnetfelds zurück in die Spule verlaufen. Vorzugsweise ist die Rückflussplatte Teil eines magnetischen Rückflussrings, der auf dessen der Spule abgekehrte Seite an den Federkörper anschließt. Der Rückschlussring kann dabei neben Teile des Lagers auch durch Teile des abzustützenden oder abstützenden Bauteils gebildet werden. Bevorzugt ist es jedoch, wenn der Rückschlussring durch das Lager selbst ausgebildet ist. Dabei kann der Rückschlussring durch weitere Federkörper des Lagers mit eingebetteten magnetischen Partikeln verlaufen, deren Federsteifigkeit ebenfalls durch das von der Spule hervorgerufene Magnetfeld variiert wird.The Coil can on its the molded body abgewandten side to a magnetic return plate adjoin, through passing through the field lines of the magnetic field back into the coil. Preferably, the reflux plate Part of a magnetic return ring, on the side facing away from the coil connects to the spring body. Of the Return ring can in addition to parts of the camp also by parts of the support or supporting component be formed. However, it is preferred if the return ring is formed by the camp itself. Here, the return ring by more spring body of the bearing with embedded magnetic particles whose Spring stiffness also caused by the coil Magnetic field is varied.
Wenn der Federkörper an der Seite, auf der die Spule angeordnet ist, an eine Scheibe anvulkanisiert ist, auf deren Rückseite die Spule liegt, ist es zumindest dann, wenn kein ausgeprägter Rückflussring vorgesehen ist, der einen magnetischen Kurzschluss über die Spule verhindert, bevorzugt, wenn diese Scheibe aus nicht ferromagnetischem Material besteht.If the spring body on the side on which the coil is arranged, to a disc vulcanized on the back the coil lies, it is at least when no pronounced return ring provided is that prevents a magnetic short circuit across the coil, preferably, if this disc is made of non-ferromagnetic material.
Die magnetischen Partikel in dem Formkörper weisen vorzugsweise eine Grundausrichtung auf, die dem Verlauf der Feldlinien des mit der Spule hervorrufbaren Magnetfelds entspricht. Dies weist darauf hin, dass ein Magnetfeld, das diese Grundausrichtung der magnetischen Partikel hervorgerufen hat, mit der Spule selbst erzeugt wurde. Vorzugsweise ist dies in einer Phase geschehen, in dem der Elastomerwerkstoff noch vergleichsweise flüssig war, so dass sich die magnetischen Partikel noch leicht an den Feldlinien ausrichten konnten.The magnetic particles in the shaped body preferably have a Basic orientation on, the course of the field lines of the with the Coil capable of magnetic field corresponds. This indicates that a magnetic field that this basic orientation of the magnetic Particle has been created with the coil itself. This is preferably done in a phase in which the elastomer material still comparatively fluid was, so that the magnetic particles still slightly on the field lines could align.
