Description
Stand der TechnikState of the art
Die Erfindung betrifft eine elektromagnetisch betätigbare Reibschaltkupplung nach dem Oberbegriff des Anspruchs 1.The invention relates to an electromagnetically actuated friction clutch according to the preamble of claim 1.
Eine derartige Reibschaltkupplung ist aus der
Offenbarung der ErfindungDisclosure of the invention
Ausgehend von dem dargestellten Stand der Technik liegt der Erfindung die Aufgabe zugrunde, eine elektromagnetisch betätigbare Reibschaltkupplung nach dem Oberbegriff des Anspruchs 1 derart weiterzubilden, dass deren radialer Bauraum gegenüber dem Stand der Technik deutlich verringert ist. Diese Aufgabe bei einer Reibschaltkupplung mit den Merkmalen des Anspruchs 1 erfindungsgemäß dadurch gelöst, dass die beiden Spule in Bezug auf die Längsachse des Antriebselements axial hintereinander angeordnet sind.Based on the illustrated prior art, the invention has the object, an electromagnetically actuated friction clutch according to the preamble of claim 1 such that their radial space compared to the prior art is significantly reduced. This object is achieved in a friction clutch with the features of claim 1 according to the invention in that the two coils are arranged axially one behind the other with respect to the longitudinal axis of the drive element.
Vorteilhafte Weiterbildungen der erfindungsgemäßen elektromagnetisch betätigbaren Reibschaltkupplung sind in den Unteransprüchen angegeben. In den Rahmen der Erfindung fallen sämtliche Kombinationen aus zumindest zwei von in den Ansprüchen, der Beschreibung und/oder den Figuren offenbarten Merkmalen.Advantageous developments of the electromagnetically actuated friction clutch according to the invention are specified in the subclaims. All combinations of at least two of the features disclosed in the claims, the description and / or the figures fall within the scope of the invention.
Um im Aufbau sowie in den Herstellkosten nachteilige Drei-Ring-Lager zu vermeiden, wird in einer bevorzugten konstruktiven Ausbildung der Lagereinrichtung für die Wirbelstromkupplung vorgeschlagen, diese auf dem Außenumfang eines (radial umlaufenden) Wandabschnitts des Trägerelements anzuordnen und als 2-Ring-Lager auszubilden.In order to avoid adverse three-ring bearings in construction and in the manufacturing costs, the bearing device for the eddy current coupling is proposed in a preferred structural design to arrange them on the outer circumference of a (radially encircling) wall portion of the support element and form a 2-ring bearing ,
Zusätzlich ist es erfindungsgemäß bei einer weiteren Variante der Erfindung vorgesehen, dass auch die anderen beiden Lagereinrichtungen jeweils als 2-Ring-Lager ausgebildet sind. Dadurch lassen sich die Herstellkosten der erfindungsgemäßen Reibschaltkupplung zusätzlich verringern.In addition, it is inventively provided in a further variant of the invention that the other two storage facilities are each formed as a 2-ring bearing. As a result, the production costs of the friction clutch according to the invention can be additionally reduced.
Eine besonders kompakte Anordnung der beiden Spulen wird erzielt, wenn die beiden Spulen durch eine Trennwand des Trägerelements axial voneinander getrennt sind, und wenn die beiden Spulen radial in etwa denselben Außendurchmesser aufweisen. Eine derartige Lösung hat darüber hinaus den Vorteil, dass der zur Verfügung stehende radiale Bauraum für die Spulen größtmöglich ausgenutzt wird.A particularly compact arrangement of the two coils is achieved when the two coils are axially separated from each other by a partition of the support member, and when the two coils have radially approximately the same outer diameter. Such a solution has the additional advantage that the available radial space for the coils is utilized as much as possible.
Um die Funktionalität bei der Betätigung der Elektromagnetanordnung der beiden Spulen zu optimieren, ist es darüber hinaus vorgesehen, dass das Lüfterrad und der Träger auf gegenüberliegenden Seiten des Trägerelements angeordnet sind.In order to optimize the functionality in the operation of the solenoid assembly of the two coils, it is also provided that the fan and the carrier are arranged on opposite sides of the support member.
Um die Größe der beiden Spulen insgesamt zu minimieren wird darüber hinaus vorgeschlagen, dass zum Schalten der Reibscheibenkupplung die beiden Spulen zunächst gemeinsam bestromt werden, und dass nach dem Schalten der Reibscheibenkupplung die der Wirbelstromkupplung zugeordnete Spule anschließend abgeschaltet wird. Dadurch kann insbesondere die Baugröße der der Reibscheibenkupplung zugeordneten Spule minimiert werden.In order to minimize the size of the two coils as a whole, it is additionally proposed that the two coils are first energized together to switch the friction disc clutch, and that after the friction disc clutch has been switched, the coil associated with the eddy current clutch is then switched off. As a result, in particular the size of the coil associated with the friction disc can be minimized.
Weitere Vorteile, Merkmale und Einzelheiten der Erfindung ergeben sich aus der nachfolgenden Beschreibung bevorzugter Ausführungsbeispiele sowie anhand der Zeichnung.Further advantages, features and details of the invention will become apparent from the following description of preferred embodiments and from the drawing.
