Description

Ausrücker releaser
Die Erfindung betrifft einen Ausrücker, insbesondere zur Betätigung mindestens einer Reibungskupplung in einem Antriebsstrang eines Kraftfahrzeugs zum wahlweisen Trennen und Verbinden zweier Wellen, bestehend aus einem konzentrisch um eine Antriebswelle angeordneten Gehäuse, in dem ein ringförmiger Kolben geführt ist, an dessen einem Ende ein Ausrücklager angeordnet ist, das sich an der Kupplung abstützt.The invention relates to a releaser, in particular for actuating at least one friction clutch in a drive train of a motor vehicle for selectively separating and connecting two shafts, consisting of a concentrically arranged around a drive shaft housing in which an annular piston is guided, arranged at one end of a release bearing is, which is supported on the clutch.
Ein derartiger Ausrücker ist aus der DE 195 18 833 A1 bekannt. Bei diesem wird die Vorlast- feder zur Abstützung des Kolbens gegen das Schleppmoment des Ausrücklagers eingesetzt.Such a releaser is known from DE 195 18 833 A1. In this case, the preload spring is used to support the piston against the drag torque of the release bearing.
Weiter ist bekannt, dass mechanische Ausrücker aus Bauraumgründen (speziell bei einer Doppelkupplung, bei der es nicht möglich ist eine Vorlastfeder einzusetzen) beispielsweise eine formschlüssige, nicht elastische Verbindung zur Schleppmomentabstützung nutzen, die jedoch durch den reibenden Kontakt zwischen den miteinander in Wirkverbindung stehenden Teilen meistens zu Verschleiß und einer Hysterese-Erscheinung bei der Betätigung der Kupplung führen kann. Dies führt außerdem zu erhöhten Schwingungen bzw. Vibrationen am Pedal, was einerseits den Komfort für den Fahrer beeinträchtigt und andererseits die Lebensdauer der Dichtungen und der Kolbenführung stark herabsetzt.It is also known that, for space reasons (especially in the case of a double clutch in which it is not possible to use a preload spring), mechanical releases utilize a form-fitting, non-elastic connection for drag torque support, which is however mostly due to the frictional contact between the parts that are in operative connection with one another can lead to wear and a hysteresis phenomenon when operating the clutch. This also leads to increased vibrations or vibrations on the pedal, which on the one hand affects the comfort of the driver and on the other hand greatly reduces the life of the seals and the piston guide.
Daher besteht die Aufgabe der Erfindung darin, einen Ausrücker zur Betätigung mindestens einer Kupplung zu schaffen, mit dem die störenden Querkräfte in Folge von Verdrehungen und Schwingungen reduziert werden, um die Lebensdauer der Dichtungen und Kolbenführung zu verlängern.Therefore, the object of the invention is to provide a releaser for actuating at least one clutch, with which the disturbing lateral forces due to twists and vibrations are reduced in order to extend the life of the seals and piston guide.
Diese Aufgabe wird mit einem Ausrücker mit den Merkmalen des Anspruchs 1 gelöst.This object is achieved with a releaser with the features of claim 1.
Danach ist ein Ausrücker, insbesondere zur Betätigung mindestens einer Reibungskupplung in einem Antriebsstrang eines Kraftfahrzeuges zum wahlweisen Trennen und Verbindung zweier Wellen, bestehend aus einem konzentrisch um eine Antriebswelle angeordneten Gehäuse, in dem eine ringförmiger Kolben geführt ist, an dessen einem Ende ein Ausrücklager angeordnet, dass sich an der Kupplung abstößt, dadurch gekennzeichnet, dass der Kolben mindestens eine Aufnahmebohrung und ebenso das Gehäuse mindestens eine Aufnahme- bohrung aufweisen, in denen die Endabschnitte eines Sicherungselements aufgenommen werden.Thereafter, a releaser, in particular for actuating at least one friction clutch in a drive train of a motor vehicle for selectively separating and connecting two shafts, consisting of a concentrically arranged around a drive shaft housing in which an annular piston is guided, arranged at one end of a release bearing, that abuts the coupling, characterized in that the piston at least one receiving bore and also the housing at least one receiving Have bore in which the end portions of a securing element are received.
In vorteilhafter Weiterbildung der Erfindung ist die mindestens eine Aufnahmebohrung im Kolben in dessen Mantelfläche und die mindestens eine Aufnahmebohrung im Gehäuse in eine dafür vorgesehene Stirnfläche des Gehäuses eingebracht. Analog dazu sind die Endabschnitte des vorzugsweise als Drahtformfeder ausgeführten Sicherungselements entsprechend abgekröpft. So sind der eine Endabschnitt der Drahtformfeder in Richtung Stirnfläche des Gehäuses und der andere Endabschnitt der Drahtformfeder in Richtung Mantelfläche des Kolbens abgekröpft. Auf diese Weise wirkt die Drahtformfeder in zwei unterschiedlichen Ebenen.In an advantageous embodiment of the invention, the at least one receiving bore in the piston in its lateral surface and the at least one receiving bore in the housing in a designated end face of the housing is introduced. Similarly, the end portions of the preferably designed as a wire form spring fuse element are bent accordingly. Thus, one end portion of the wire-forming spring in the direction of the end face of the housing and the other end portion of the wire-forming spring are bent in the direction of the lateral surface of the piston. In this way, the wire-forming spring acts in two different planes.
Aus Kostengründen ist es weiter vorteilhaft, eine Drahtformfeder mit kreisförmigem Querschnitt einzusetzen. Allerdings sind auch andere Querschnittsformen denkbar, die dann jedoch auch mit den Querschnitten der Aufnahmebohrungen in Kolben und Gehäuse übereinstimmen sollten.For cost reasons, it is also advantageous to use a wire form spring with a circular cross section. However, other cross-sectional shapes are conceivable, but then should also coincide with the cross sections of the mounting holes in the piston and housing.
Zur Gewährleistung einer optimalen Sicherungsfunktion gegen ein Verdrehen des Kolbens gegenüber seinem Gehäuse ist es vorteilhaft, die Bogenlänge der Drahtformfeder an den Abstand zwischen den jeweiligen Aufnahmebohrungen im Gehäuse und Kolben anzupassen.To ensure optimum safety function against rotation of the piston relative to its housing, it is advantageous to adapt the arc length of the wire-forming spring to the distance between the respective receiving bores in the housing and piston.
Die Erfindung wird nachfolgend anhand eines Ausführungsbeispiels und zugehöriger Zeichnungen näher erläutert.The invention will be explained in more detail with reference to an embodiment and associated drawings.

Figur 1 : eine perspektivische Darstellung eines Ausrückers für eine Reibungskupplung,FIG. 1 is a perspective view of a release mechanism for a friction clutch;
Figur 2: ein Längsschnitt durch den Ausrücker gemäß Figur 1 ,FIG. 2 shows a longitudinal section through the release device according to FIG. 1,
Figur 3: eine Draufsicht auf den Ausrücker gemäß Figur 1 ,FIG. 3 shows a plan view of the release device according to FIG. 1,
Figur 4: eine vergrößerte Darstellung eines Sicherungselements. In den Figuren 1 und 2, die sich nur durch unterschiedliche Darstellungsweisen unterscheiden (in Figur 1 ist der Ausrücker perspektivisch und in Figur 2 im Längsschnitt dargestellt), ist das Gehäuse 1 eines Ausrückers dargestellt, in dem in einer dafür vorgesehenen Aufnahmenut, ein ringförmiger Kolben 2 aufgenommen und axial geführt wird. Der Kolben 2 ist mit einem Dichtelement 3 verbunden, das diesen zu dem in der Aufnahmenut gebildeten Druckraum hin in gewohnter Weise abdichtet. Das andere Ende des Kolbens 2 ist mit einem Ausrücklager 4 verbunden, dessen äußerer Lagerring mit einer Tellerfeder, einer nicht dargestellten Kupplung in Wirkverbindung bringbar ist. Weiter ist in diesen Figuren ein Sicherungselement 5 sichtbar, dessen Endabschnitt A' in einer Aufnahmebohrung A in einer dafür vorgesehenen Stirnfläche C am Gehäuse 1 des Ausrückers und dessen Endabschnitt B' in einer radial in die Mantelfläche des Kolbens 2 einbrachten Aufnahmebohrung B verrastet. Dadurch, dass, wie aus Figur 1 besonders hervorgeht, die Endabschnitte A' und B' des vorzugsweise als Drahtformfeder ausgeführten Sicherungselements 5 einerseits mit dem Gehäuse 1 und andererseits mit dem Kolben 2 verbunden sind, wird so mittels der Drahtformfeder 5 eine Verbindung zwischen einem statischen und einem bewegbaren Bauteil hergestellt. Auf diese Weise wird eine Verdrehsicherung realisiert. Dazu ist der Endabschnitt A' in Richtung der Stirnfläche C des Gehäuses 1 und der Endabschnitt B' der Drahtformfeder 5 in Richtung Mantelfläche des Kolbens 2 abgekröpft (siehe auch Figur 4).Figure 4: an enlarged view of a fuse element. In Figures 1 and 2, which differ only by different ways of representation (in Figure 1, the releaser is shown in perspective and in Figure 2 in longitudinal section), the housing 1 of a releaser is shown, in which in a designated receiving groove, an annular piston 2 is received and guided axially. The piston 2 is connected to a sealing element 3, which seals it to the pressure chamber formed in the receiving groove in the usual way. The other end of the piston 2 is connected to a release bearing 4, the outer bearing ring with a plate spring, a coupling, not shown, can be brought into operative connection. Further, in these figures, a securing element 5 is visible, the end portion A ' in a receiving bore A in a designated end face C on the housing 1 of the releaser and the end portion B ' in a radially inserted into the lateral surface of the piston 2 receiving bore B locked. Characterized in that, as shown particularly in FIG. 1, the end sections A ' and B ' of the securing element 5, which is preferably designed as a wire form spring, are connected, on the one hand, to the housing 1 and, on the other hand, to the piston 2, then a connection is made between a static one by means of the wire form spring 5 and a movable member. In this way, a rotation is realized. For this purpose, the end portion A ' in the direction of the end face C of the housing 1 and the end portion B ' of the wire-forming spring 5 in the direction of the lateral surface of the piston 2 is bent (see also Figure 4).
Figur 3 zeigt eine Draufsicht auf den Ausrücker ohne Ausrücklager, wie in den Figuren 1 und 2 dargstellt. Aus dieser wird das Gehäuse 1 mit dem darin geführten Kolben 2 sichtbar. Weiter geht aus dieser Figur 3 hervor, dass zum sicheren Abfangen eines Drehmomentes zwei Drahtformfedern 5 verwendet werden. Somit ist eine Drahtformfeder 5 auf jeweils einer Hälfte des Gehäuses 1 und damit auch des Kolbens 2 eingesetzt, wobei deren Endabschnitte A' und B' in den jeweiligen Aufnahmebohrungen A und B im Kolben 2 und im Gehäuse 1 aufgenommen werden.Figure 3 shows a plan view of the releaser without release bearing, as dargstellt in Figures 1 and 2. For this, the housing 1 with the piston 2 guided therein is visible. Further, it is apparent from this figure 3 that two wire form springs 5 are used for safe interception of a torque. Thus, a wire-shaped spring 5 is inserted on one half of the housing 1 and thus also of the piston 2, wherein the end portions A ' and B ' are received in the respective receiving bores A and B in the piston 2 and in the housing 1.
In Figur 4 ist die Drahtformfeder 5 perspektivisch dargestellt. In diesem Ausführungsbeispiel weist sie vorteilhafter Weise einen kreisförmigen Querschnitt auf und ist bogenförmig ausgeführt, wobei die Länge und der Radius des Bogens an den größten zu umschlingenden Durchmesser des Gehäuses angepasst ist. Allerdings ist ebenso gut auch ein anderer Querschnitt für die Drahtstromfeder 5 denkbar. Die Bogenlänge der Drahtformfeder 5 zwischen ihren abgekröpften Endabschnitten A', B' sollte dabei der Länge zwischen den Aufnahmebohrungen A, B entsprechen, um eine optimale Sicherungsfunktion zu gewährleisten. Durch diese konstruktive Ausführung einer Verdrehsicherung werden die auftretenden Querkräfte in Folge von Verdrehungen und Schwingungen im Ausrücker reduziert, was zur Verlängerung der Lebensdauer des Dichtelements 3 und der Kolbenführung folgt. In Figure 4, the wire form spring 5 is shown in perspective. In this embodiment, it advantageously has a circular cross-section and is arcuate, wherein the length and the radius of the arc is adapted to the largest diameter to be wrapped around the housing. However, another cross section for the wire current spring 5 is just as well conceivable. The arc length of the wire form spring 5 between its bent end portions A ' , B ' should correspond to the length between the mounting holes A, B, to ensure an optimal backup function. This structural design of an anti-rotation device reduces the transverse forces that occur as a result of twists and oscillations in the releaser, which leads to an extension of the service life of the sealing element 3 and the piston guide.
