Definitions
- the invention relates to a release unit for a double clutch with the features of the preamble of claim 1.
- a dual clutch summarizes essentially two separate coupling units, which independently of each other via an associated Ausrüc kvorraum interrupt a connection to a transmission input shaft and can manufacture herstel len.
- a preferred field of application of such a dual clutch is the use with a dual-clutch transmission.
- the first clutch unit usually operates the odd gear stages and the second clutch unit the straight gears. In this way, while on the one clutch unit currently the torque from the engine to the transmission wbe, another gear is already selected to be able to then switch without interrupting the traction of the current gear in the preselected gear.
- the transmission input shaft for this purpose is preferably composed of two concentric shafts, that is from egg ner hollow shaft with an internal Vol Iwelle.
- Such a double clutch is already known from DE 101 16 705 A1.
- the coupling units are in this two concentrically arranged Nehmerzy- linderkolben or actuating piston, that is, an inner slave cylinder piston and an outer slave cylinder piston, provided.
- the inner and the outer e slave cylinder piston is guided in each case in an annular cylindrical cylinder housing.
- This slave cylinder constructed in this way is also referred to as CSC (Concentric Slave Cy Linder).
- the two cylinder housings are thus also arranged concentrically to each other and form an inner slave cylinder and an outer N ehmerzylinder in which the slave cylinder pistons are arranged axially movable relative to each other.
- a disadvantage of this solution is that in the housing of the release unit or the dual-clutch CS Cs for each slave cylinder piston, a groove ei is introduced. In the operation of the dual-clutch CSC, damage may occur to the seals sliding over these grooves and placed end-to-end on the slave piston, thereby causing the double-clutch CSC to leak and thus degrade its lifetime.
- the object of the invention is to provide a clutch release unit for a double clutch with drag drag support between the slave cylinder piston and the CSC housing without introducing openings in the CSC housing.
- the release unit for a double clutch from egg nem a plurality of annular housing walls having housing so that concentric with the axis of symmetry of the release unit, two annular chambers are provided, in each of which a pressure chamber sealing annular Nehmerzylinderkoiben is arranged axially displaceable, by one between them and the housing / housing wall provided against rotation on its rotational movement is changed.
- a pressure chamber sealing annular Nehmerzylinderkoiben is arranged axially displaceable, by one between them and the housing / housing wall provided against rotation on its rotational movement is changed.
- a pressure chamber sealing annular Nehmerzylinderkoiben is arranged axially displaceable, by one between them and the housing / housing wall provided against rotation on its rotational movement is changed.
- a pressure chamber sealing annular Nehmerzylinderkoiben is arranged axially displaceable, by one between them and the housing / housing wall provided against rotation on its rotational
- the drag torque support has at least one radial extension, which also engages in at least one groove inserted in the slave cylinder piston.
- an advantageous embodiment of the invention provides that the drag torque support consists of metallic or non-metallic material.
- Figure 1 shows a release unit according to the invention in section, with both in
- FIG. 2 shows an exploded view of the release unit according to FIG. 1.
- FIG. 1 shows a release unit 1 in section, which is arranged in the installed state konz entrisch on a transmission input shaft, not shown.
- This release unit consists of a housing 2, which may consist of plastic, metallic or non-metallic material.
- a slave cylinder piston 3, 4 is guided axially movable, so that these annular slave cylinder piston 3, 4 are also arranged concentrically to each other.
- each slave cylinder piston 3, 4 is for sealing a pressure chamber. mes with a seal 5, 6, d he is connected to this in each case via a sealing ring carrier 7, 8.
- each slave cylinder piston 3, 4 is connected to an operating unit, not shown, a partial clutch of a doubling clutch acting release bearing 9, 10.
- rings are provided as drag torque supports 11, 12, ie, with the housing walls 2a, 2b, for example by means of shrinking, gluing , Pressing their inner walls 11 b, 12 b, are firmly connected.
- This e drag torque supports 1 1, 12 are each provided with at least one radial extension 11 a, 12 a.
- Figure 2 shows the release unit 1 in an exploded view, from this all components are visible as individual parts in their geometric shape, and in which position they are connected together.
- the housing 2 with its two annular wells can be seen, in which the two pistons 3, 4 are used.
- the two Schleppmomentabstützungen 11, 12 ersichtl I which are not yet firmly m associated with the corresponding housing wall 2a, 2b in this figure.
- the connection is made, as already described in Figure 1, for example, by shrinking the inner wall 11 b, 1 2b of the drag torque support 11, 12 on the respective housing wall 2a, 2b.
