Abstract
Description
Die Erfindung betrifft einen Schwingungsdämpfer mit einem Zuganschlag gemäß dem Oberbegriff von Patentanspruch 1.The Invention relates to a vibration damper with a train stop according to the generic term of claim 1.
Aus
der
Prinzipiell
ist die Federrate eines derartigen elastischen Körpers vergleichsweise groß. Man erhält zwar
einen u. U. sehr kompakt bauenden Zuganschlag, doch kann dieser
Zuganschlag die Kolbenstangenausfahrbewegung häufig nicht ausreichend komfortabel
begrenzen. Deshalb werden sehr häufig Zuganschläge mit Schraubenfeder
verwendet, wie z. B. in der
Aufgabe der vorliegenden Erfindung ist es einen Schwingungsdämpfer mit einem Zuganschlag mit einer gestuften Federkraftkennlinie zu erreichen, der einerseits kostengünstig und einen kleinen axialen Bauraum benötigt.task In the present invention, it is a vibration damper to achieve a train stop with a stepped spring force characteristic, the on the one hand, inexpensive and requires a small axial space.
Erfindungsgemäß wird die Aufgabe dadurch gelöst, dass die erste Feder als ein elastischer Körper und die zweite Feder als eine Schraubenfeder ausgeführt ist, wobei der elastische Körper von einer Manschette in seiner radialen Durchmesservergrößerung begrenzt ist.According to the Task solved by that the first spring as an elastic body and the second spring as a coil spring executed is, the elastic body limited by a cuff in its radial diameter increase is.
Durch die Kombination der beiden verschiedenartigen Federn wird eine gestufte Federkennlinie mit sehr einfachen Mitteln erreicht. Die Manschette schützt den elastischen Körper, so dass auch die zweite Feder mit einer relativ kleinen Federkonstante ausgeführt sein kann.By the combination of the two different types of springs becomes a graded one Spring characteristic curve achieved with very simple means. The cuff protects the elastic body, so that the second spring can also be designed with a relatively small spring constant can.
Zur Vermeidung von Oberflächenbeschädigungen der Kolbenstange durch die Schraubenfeder ist der zweite Träger als ein Federteller mit einer Zentrierhülse ausgeführt.to Avoiding surface damage the piston rod through the coil spring is the second carrier as a spring plate with a centering sleeve.
Damit die Schraubenfeder innerhalb des Schwingungsdämpfers vollständig radial zentriert ist, ohne dass eine zylinderseitige Abstützung notwendig ist, weist die Schraubenfeder an beiden Enden einen Federteller auf.In order to the coil spring inside the vibration damper is completely radial is centered without the need for a cylinder-side support, the coil spring has a spring plate at both ends.
Bei einer ersten vorteilhaften Variante sind der erste Träger und die Manschette einteilig ausgeführt sind. Das eröffnet die Möglichkeit, dass der zweite und der dritte Träger als identische Bauteile ausgeführt sind. Folglich gibt es keine Fehlerquelle, aufgrund der der Zuganschlag durch vertauschte Träger nicht die gewünschte Funktion erfüllt.at a first advantageous variant are the first carrier and the cuff is made in one piece are. That opens up the possibility, that the second and the third carrier are designed as identical components. Hence there is no source of error due to which the train stop by exchanged carriers not the one you want Function fulfilled.
Man kann auch vorsehen, dass der zweite Träger und die Manschette einteilig ausgeführt sind. Der erste Träger ist in vielen Schwingungsdämpfern enthalten, die lediglich eine Ausfahrbegrenzung ohne Zuganschlagfeder aufweisen, beispielsweise um einen Ausfederweg zu begrenzen, wie er beim Radwechsel vorkommt. Wenn der zweite Träger und die Manschette einteilig ausgeführt sind, besteht die Möglichkeit, dass ein bereits vorhandener Träger weiter benutzt werden kann. Folglich kann auch die Baueinheit Kolbenstange-erster Träger unabhängig von der Verwendung eines Zuganschlags hergestellt und lagermäßig sehr einfach verwaltet werden.you can also provide that the second carrier and the cuff are in one piece accomplished are. The first carrier is contained in many vibration dampers, which only have an extension limitation without a tension stop spring, for example to limit a rebound travel, such as when changing a wheel occurs. If the second carrier and the cuff is made in one piece, there is the possibility that an existing carrier continues can be used. As a result, the piston rod assembly can also be first carrier independent of the use of a train stop made and stock very easily managed.
Bei einer weiteren Ausführung sind der Federteller und die Manschette einteilig ausgeführt sind.at another version are the spring plate and the sleeve are made in one piece.
Es kann durchaus sinnvoll sein, wenn der zweiten Feder eine dritte Feder in Reihe nachgeschaltet ist, die von einem dritten Träger auf der zweiten Feder gehalten wird.It can make sense if the second spring is a third Spring is connected in series by a third carrier the second spring is held.
Um die erste und dritte Feder während der Montage leichter handhaben zu können, bilden die erste Feder mit dem zweiten Träger und die dritte Feder mit dem dritten Träger eine Presspassung bilden.Around the first and third spring during The first spring is to be able to handle the assembly more easily with the second carrier and the third spring form an interference fit with the third carrier.
Des weiteren kann vorgesehen sein, dass der zweite und der dritte Träger mit der Schraubenfeder eine Montageverbindung eingehen.Of it can further be provided that the second and the third carrier with make an assembly connection with the coil spring.
