Hydraulische KupplungsbetätigungseiarichttingHydraulic clutch actuation device

Die Neuerung betrifft eine hydraulische Kupplungsbetätigungseinrichtung nach dem Oberbegriff des Anspruchs i. The innovation relates to a hydraulic clutch actuating device according to the preamble of claim i.

Aus dem DE-GM 38 15 881 ic-.·, eine &. ,'artige Kupplungsbetstigungseinrichtung bekannt, die sich in der Praxis bewährt hat. Dabei hat sich gezeigt, daß es vereinzelt zu Beschädigungen des Faltenbalges kommen kann. Durch das innere Reibmoment des Lagers entsteht eine resultierende Kraft -n Umfangsrichtung. Diese Kraft wird über die Druckfeder, die gleichzeitig als Vorla3tfeder eingesetzt ist, am Gehäuse abgestützt. Bei diesem Vorgang verdreht sich jedoch das Lagergehäuse mit dem Kolben sowie die reibschlüssig mit dem Lagergehäuse verbundene Schutzkappe gegenüber dem Gehäuse, was zu einer Verdrillung des Faltenbalges führt. Diese Einschnürung bewirkt eine Verringerung der Nutzungsdauer des Faltenbalges besonders dann, wenn er sich zwischen die Federwindungen klemmt.A type of clutch actuation device is known from DE-GM 38 15 881 ic- . , which has proven itself in practice. It has been shown that damage to the bellows can occur in isolated cases. The internal frictional moment of the bearing creates a resulting force in the circumferential direction. This force is supported on the housing by the compression spring, which is also used as a preload spring. During this process, however, the bearing housing with the piston and the protective cap, which is frictionally connected to the bearing housing, rotate relative to the housing, which leads to a twisting of the bellows. This constriction reduces the service life of the bellows, particularly if it gets jammed between the spring coils.

Es ist deshalb Aufgabe der Neuerung, eine Kupplungsbetätigungseinrichtung der eingangs genannten Art so weiterzubilden, daß die genannten Nachteile vermieden werden und mit einfachen Mitteln eine Belastung des Faltenbalgeö in Umfangsrichtung vermindert wird.It is therefore the aim of the innovation to further develop a clutch actuation device of the type mentioned at the beginning in such a way that the disadvantages mentioned are avoided and a load on the bellows in the circumferential direction is reduced by simple means.

Die Lösung der Aufgabe erfolgt dadurch, daß der Faltenbalg an seinen Sitzstellen am Gehäuse und/oder am Lagergehäuse verdrehbar ausgebildet ist, in dem er dort einen Gleitring aufweist oder mit einer reibungsarmen Beschichtung versehen ist.The problem is solved by the bellows being designed to be rotatable at its seating points on the housing and/or on the bearing housing by having a sliding ring there or by being provided with a low-friction coating.

Die Neuerung soll an einem Ausführungsbeispiel dargestellt werden.The innovation will be illustrated using an example.

Figur 1 zeigt eine neuerungsg^^äße Kupplungsbetätigungseinrichtung im SchnittFigure 1 shows an innovative clutch actuation device in section

Figur 2 zeigt die Sitzstelle am Gehäuse vergrößert dargestellt.Figure 2 shows the seat on the housing enlarged.

In Figur 1 ist das Gehäuse mit 1 bezeichnet. Es weist einen Anschluß 2 für die Druckmittelversorgung auf, die in den Druckraum 3 führt. Darin ist ein mit einer Dichtung 4 versehener Kolben 5 axial verschiebbar angeordnet, der an seinem anderen Ende das Kupplungslager 6 trägt. Zwischen dem Kupplungslager 6 und dem Gehäuse 1 ist eine Druckfeder 7 angeordnet, welche das Lager 6 vorspannt. Ein am Lager 6 und am Gehäuse 1 angeordneter Faltenbalg 8 dichtet die Kupplungsbetätigungseinrichtung gegen Schmutz ab.In Figure 1, the housing is designated 1. It has a connection 2 for the pressure medium supply, which leads into the pressure chamber 3. A piston 5 provided with a seal 4 is arranged in it so that it can move axially, which carries the clutch bearing 6 at its other end. A compression spring 7 is arranged between the clutch bearing 6 and the housing 1, which preloads the bearing 6. A bellows 8 arranged on the bearing 6 and the housing 1 seals the clutch actuation device against dirt.

In der dargestellten Ausführung ist der Faltenbalg 8 fest mit dem Lagergehäuse 6 verbunden, während er an seiner Sitzstelle am Gehäuse 1 mit einem Gleitring 9 versehen ist und sich somit verdrehen kann.In the embodiment shown, the bellows 8 is firmly connected to the bearing housing 6, while it is provided with a sliding ring 9 at its seat on the housing 1 and can therefore rotate.

Wie Figur 2 zeigt ist dieser Gleitring 9 radial und axial mit Spiel zwischen dem Gehäuse 1 und der Federauflage 10 angeordnet, so daß dar Faltenbalg 8 einer Verdrehung des Lageraußenringes gegenüber dem Gehäuse folgen kann· Anstelle eines Gleitringes kann der Faltenbalg 8 an seiner Sitzstelle auch mit einer reibungsarmen Beschichtung versehen sein.As Figure 2 shows, this sliding ring 9 is arranged radially and axially with play between the housing 1 and the spring support 10, so that the bellows 8 can follow a rotation of the bearing outer ring relative to the housing. Instead of a sliding ring, the bellows 8 can also be provided with a low-friction coating at its seat.
