Definitions
- 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.
- Such a releaser is known from DE 195 18 833 A1.
- the preload spring is used to support the piston against the drag torque of the release bearing.
- 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.
- 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.
- 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.
- the end portions of the preferably designed as a wire form spring fuse element are bent accordingly.
- 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.
- FIG. 1 is a perspective view of a release mechanism for a friction clutch
- FIG. 2 shows a longitudinal section through the release device according to FIG. 1,
- FIG. 3 shows a plan view of the release device according to FIG. 1,
- Figure 4 an enlarged view of a fuse element.
- 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.
- 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.
- 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.
- 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).
- Figure 3 shows a plan view of the releaser without release bearing, as darg Robinson in Figures 1 and 2.
- the housing 1 with the piston 2 guided therein is visible.
- two wire form springs 5 are used for safe interception of a torque.
- 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.
- 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.
- 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.
