Abstract
Description
Die Erfindung bezieht sich auf eine Tellerfeder, insbesondere auf eine Tellerfeder zum Einbau in ein Getriebe eines Kraftfahrzeugs gemäß dem Oberbegriff des Patentanspruchs 1. The invention relates to a plate spring, in particular a disc spring for installation in a transmission of a motor vehicle according to the preamble of
Aus dem Stand der Technik ist bekannt, bei Fahrzeuggetrieben Tellerfedern einzusetzen. Beispielsweise werden Tellerfedern in Lamellenkupplungen von Automatgetrieben als Rückstellfedern eingesetzt. Durch die Tellerfeder einer Lamellenkupplung wird der in einem Zylinder axialverschiebbar angeordnete und in der Regel im Schließsinne der Kupplung hydraulisch betätigbare Kupplungskolben mit einer Rückstellkraft beaufschlagt, durch die die Lamellenkupplung bei nicht mit Hydraulikdruck beaufschlagten Kolben geöffnet wird und im geöffneten Zustand gehalten wird. From the prior art it is known to use disc springs in vehicle transmissions. For example, disc springs are used in multi-plate clutches of automatic transmissions as return springs. By the plate spring of a multi-plate clutch of a cylinder axially displaceable and usually in the closing direction of the clutch hydraulically actuated clutch piston is acted upon by a restoring force through which the multi-plate clutch is opened when not acted upon by hydraulic pressure piston and held in the open state.
Aus der
In der Regel sind die verwendeten Tellerfedern als innengeschlitzte Tellerfedern ausgeführt und weisen demnach einen ungeschlitzten, federnden Ring auf, an den sich radial betrachtet nach innen Zungen anschließen, die als Hebelarme des federnden Rings dienen. In general, the disc springs used are designed as internally slotted disc springs and therefore have an unslotted, resilient ring, to which radially inwardly tongues connect, which serve as lever arms of the resilient ring.
Bei der Montage von Tellerfedern kann es zu Fehlmontagen kommen; hierbei werden die Tellerfedern in der falschen Richtung montiert, wodurch in nachteiliger Weise die benötigte Funktionalität nicht zur Verfügung steht. In einem derartigen Fall muss für den Fall eines Getriebes das Getriebe mit hohem Aufwand rückmontiert werden, um eine Behebung des Fehlers zu ermöglichen. When mounting disc springs may lead to incorrect assembly; In this case, the disc springs are mounted in the wrong direction, which disadvantageously the required functionality is not available. In such a case, in the case of a transmission, the transmission must be rear-mounted at great expense in order to enable the fault to be remedied.
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine Tellerfeder, insbesondere eine Tellerfeder zum Einbau in ein Getriebe eines Kraftfahrzeugs anzugeben, bei der eine Fehlmontage konstruktiv ausgeschlossen wird. The present invention has for its object to provide a plate spring, in particular a plate spring for installation in a transmission of a motor vehicle, in which a faulty mounting is excluded constructive.
Diese Aufgabe wird durch die Merkmale des Patentanspruchs 1 gelöst. Weitere erfindungsgemäße Ausgestaltungen und Vorteile gehen aus den Unteransprüchen hervor. This object is solved by the features of
Demnach wird eine Tellerfeder, insbesondere eine Tellerfeder zum Einbau in ein Getriebe eines Kraftfahrzeugs vorgeschlagen, umfassend einen ungeschlitzten, federnden Ring, an den sich radial betrachtet nach innen Zungen anschließen, bei der die Zungen eine Kröpfung aufweisen, die im korrekt montierten Zustand der Tellerfeder als innere Anlage der Tellerfeder und zudem als Fehlmontagesicherung dient, derart, dass bei Fehlmontage der Sicherungsring zur axialen Vorspannung und Sicherung der Tellerfeder nicht montierbar ist, da durch die Kröpfung die zur Montage des Sicherungsrings erforderliche axiale Verschiebung des radial betrachtet inneren Endes der Zungen verhindert wird. Accordingly, a plate spring, in particular a disc spring proposed for installation in a transmission of a motor vehicle, comprising an unslotted, resilient ring to which radially inwardly tongues connect, in which the tongues have a crank, in the correctly assembled state of the plate spring as inner abutment of the plate spring and also serves as a false assembly assurance, such that in incorrect assembly of the circlip for axial preload and securing the plate spring is not mountable, as required by the crank for mounting the circlip axial displacement of the radially inner end of the tongues is prevented.
Durch die erfindungsgemäße Konzeption wird auf einfache und kostengünstige Weise gewährleistet, dass eine Fehlmontage der Tellerfeder ausgeschlossen wird, ohne die Funktionalität der Tellerfeder zu beeinträchtigen. The inventive concept is ensured in a simple and cost-effective manner that incorrect assembly of the plate spring is excluded, without affecting the functionality of the plate spring.
Die Erfindung wird im Folgenden anhand der beigefügten Figuren beispielhaft näher erläutert. Es zeigen: The invention will be explained in more detail below by way of example with reference to the attached figures. Show it:

Im Fall einer Fehlmontage ist eine Montage des Sicherungsrings
Durch die erfindungsgemäße Ausgestaltung der Tellerfeder wird mit geringem konstruktiven Aufwand bei der Montage sofort erkannt, ob eine Fehlmontage vorliegt, was darin resultiert, dass eine Rückmontage, die mit erheblichem Aufwand verbunden ist, nicht erforderlich ist. Due to the inventive design of the plate spring is immediately recognized with little design effort in the assembly, whether a faulty assembly is present, resulting in that a rear assembly, which is associated with considerable effort, is not required.
