Abstract
Description
Die Erfindung betrifft eine Dämpfereinheit, insbesondere eine Gasfeder-Dämpfereinheit, mit zumindest einem Überströmkanal, der über eine federnde Drosselscheibe abgedeckt ist, die auf einer Auflagefläche aufliegt.The The invention relates to a damper unit, in particular a gas spring damper unit, with at least one overflow channel, the over a resilient throttle plate is covered, which rests on a support surface.
Bei einem Einsatz von Drosselscheiben, die auch „Shims" genannt werden, bei hydraulischen oder pneumatischen Dämpfern, wird eine möglichst hohe Dichtigkeit gefordert. Dabei gibt es insbesondere bei herkömmlichen Drosselscheiben fertigungsbedingte Probleme, insbesondere führen Unebenheiten zu Leckagen, die nicht erwünscht sind.at a use of throttle disks, which are also called "shims", hydraulic or pneumatic dampers, will be as high as possible Tightness required. There are in particular in conventional Throttle wheels production-related problems, in particular lead to bumps Leaks that are not desired are.
Herkömmliche Drosselscheiben werden aus einem Bandmaterial hergestellt, das von sogenannten Coils abgerollt wird. Sie haben daher von vornherein eine gebogene Gestalt, die abhängig von dem Biegeradius des Coils des Bandmaterials ist, Die Drosselscheiben werden in der Regel durch einen Stanzprozeß hergestellt, der ebenfalls Verformungen in der Drosselscheibe hinterlässt. Es ist möglich, diese Verformungen teilweise durch Richten zu kompensieren, jedoch wird die erforderliche Ebenheit zur möglichst vollständigen Abdichtung des Überströmkanals in der Regel nicht erreicht. Solche Unebenheiten können akzeptiert werden, wenn die Drosselscheiben im Betrieb mit einer hinreichenden Kraft auf die Auflageflächen gepresst werden. Dies wird gemäß dem Stand der Technik beispielsweise durch eine unterschiedliche Höhe der inneren und äußeren Auflageflächen versucht, jedoch sind solche Auflageflächen schwer herzustellen und können nicht gut geschliffen werden. Zusätzliche Bauteile, wie Federelemente, sind sowohl in der Fertigung als auch in der Montage aufwendig.conventional Throttle discs are made from a strip material made by so-called coils is unrolled. You therefore have from the beginning a curved figure that is dependent from the bend radius of the coil of the strip material is, the throttle slices are usually made by a stamping process, which also Deformations in the throttle disc leaves. It is possible this Partial deformation by straightening, however, becomes the required flatness to the possible complete Sealing the overflow channel usually not reached. Such bumps can be accepted when the throttle disks in operation with a sufficient Force on the bearing surfaces be pressed. This will be in accordance with the state the technology for example by a different height of the inner and outer bearing surfaces trying however, such contact surfaces are hard to make and can not be sanded well. Additional components, such as spring elements, Both in production and in assembly consuming.

Nachteilig an dem bekannten Stand der Technik ist die teilweise aufwendige Montage der Drosselscheiben mit Federelementen, die für eine ausreichend Vorspannung sorgen sowie die mangelnde Dichtheit der Scheibenstapel.adversely in the known state of the art is the partially expensive Mounting the throttle plates with spring elements sufficient for one Preload worry as well as the lack of tightness of the disk stacks.
Ausgehend von diesem Stand der Technik liegt der Erfindung die Aufgabe zugrunde, eine Dämpfereinheit bereitzustellen, bei der ohne aufwendige Maßnahmen eine ausreichende Vorspannung auf die Drosselscheiben aufgebracht werden kann, um die Dichtheit der Drosselscheibe zu gewährleisten.outgoing From this prior art, the invention is based on the object a damper unit to provide, in which without consuming measures sufficient preload The throttle disks can be applied to the tightness of the To ensure throttle plate.
Erfindungsgemäß wird diese Aufgabe durch eine Dämpfereinheit mit den Merkmalen des Anspruchs 1 gelöst, bei der die Drosselscheibe als Tellerfeder ausgebildet ist und unter Vorspannung auf der Auflagefläche aufliegt. Tellerfedern haben im nicht montierten Zustand eine leicht konische Form. Im montierten Zustand werden die Tellerfedern, die als Drosselscheiben eingesetzt werden, flach auf die vorteilhafterweise ebenen Auflageflächen gedrückt, was zur Folge hat, dass die Drosselscheibe selbst eine Vorspannung ausbildet und eine sauberere und dichte Auflage auf der Auflagefläche gewährleistet.According to the invention this Task by a damper unit solved with the features of claim 1, wherein the throttle disc is designed as a plate spring and rests under pretension on the support surface. Disc springs have a slightly conical when not assembled Shape. When assembled, the disc springs are used as throttle discs are used, pressed flat on the advantageously flat bearing surfaces, which As a result, the throttle disk itself forms a bias voltage and ensures a cleaner and more dense pad on the support surface.
Eine Weiterbildung der Erfindung sieht vor, dass die Tellerfeder über eine Halteeinrichtung unter Vorspannung auf der Auflagefläche gehalten wird, vorzugsweise ist die Halteeinrichtung als eine Mutter oder eine formschlüssige Rasteinrichtung ausgebildet.A Development of the invention provides that the plate spring on a Holding device held under pretension on the support surface is preferably, the holding device as a mother or a form-fitting Locking device formed.
