Definitions
- the invention relates to a clutch, which has a disengaging device, which can be connected to a transmission via a gear-side contact surface, and a pressure plate, which presses a driver against a counter surface in an engaged position, and which is disengaged by the disengaging device to disengage the clutch Position can be moved in which the pressure plate does not press the driver against a counter surface.
- the invention has for its object to provide an easily removable clutch.
- the disengaging device comprises a pulling mechanism which pulls the pressure plate from the engaged position into the disengaged position when the clutch is disengaged, and in that the transmission-side contact surface is designed as a separation point between the release device and the transmission on which the Disengaging device can be solved in the installed state of the transmission.
- the contact surface advantageously runs in the radial direction.
- holding means are provided for connecting to the transmission, which can be released when the disengaging device is installed.
- a secure connection of the transmission and clutch is achieved in that the holding means consist of clamping means which radially enclose the separation point.
- Disassembly in particular is simplified in that the clamping means are formed from two half-shells.
- the holding means comprise a first component and a second component, the first component being fixed to the transmission, the second component being fixed to the releaser, and the first and second components being connected to one another via connecting means are.
- a particularly stable attachment is achieved in that the first or the second component is arranged radially on the inside and is radially enclosed by the other component.
- the connecting means extend essentially parallel to the axial direction of the coupling.
- the pulling mechanism has a connecting element which connects a releaser and a release bearing to one another.
- the assembly of the coupling is facilitated in that the connecting element is designed as a locking element.
- the connecting element is designed as a locking element.
- the functions are separated.
- the releaser can be fixed on the gearbox on the gear-side contact surface of the clutch and then moved towards the driver until the locking element engages and thereby the connecting element
- the disassembly can be carried out by loosening the gearbox and release device in the installed state at the separation point. In this way it is not necessary to provide a mechanism by means of which the latching element is moved from the latched position into the release position.
- the locking element is pressed under spring force from a release position into a locking position.
- the invention further relates to a motor-transmission unit with a clutch of the type described above.
- a housing of the transmission has at least one recess, so that the connecting means are accessible from the outside for releasing the connecting means when the coupling is installed. This is particularly advantageous if the connecting means extend essentially parallel to the axial direction of the coupling.
- FIG. 1 shows a cross section through a coupling according to the invention according to a first embodiment
- FIG. 2 shows a cross section through a coupling according to the invention according to a second embodiment
- Fig. 3 shows a cross section through an inventive coupling according to a third embodiment.
- Figure 1 shows a clutch for a passenger car, which comprises a pressure plate 1, which presses a drive plate 2 against a counter surface 3 in the engaged position shown.
- the driving plate 2 is non-rotatably, if necessary by means of a torsion spring / damper set, arranged on a shaft 4, which is the input shaft of a transmission.
- the counter surface 3 is formed by the flywheel 5 of an internal combustion engine, not shown.
- the driving plate 2 has friction linings for abutment on the counter surface 3 and on the pressure plate 1.
- a clutch spring 6 acts on a radially outer section of the pressure plate 1 and presses the pressure plate 1 towards the counter surface 3.
- a disengaging device 7 In order to move the pressure plate 1 from its engaged position against the force of the clutch spring 6 into the disengaged position in which the clutch is separated, a disengaging device 7 is provided.
- This comprises a pulling mechanism 8 which is fastened on the one hand to the pressure plate 1 and on the other hand to a hydraulically operated central release 9.
- a release bearing 10 with rolling elements 11 is integrated in the pull mechanism 8.
- the pulling mechanism 8 further comprises an outer bearing part 12, which is connected to the pressure plate 1 and an inner bearing part 13, which is connected to the central release 9.
- the rolling elements 11 of the release bearing 10 are arranged between the bearing parts 12, 13.
- the release bearing 10, which is designed as a shoulder ball bearing, is dimensioned so that the increased forces can be absorbed compared to conventional central releasers.
- the disengaging device 7 is actuated hydraulically and for this purpose has a first hydraulic element 15 and a second one which is movable relative to the latter Hydraulic element 16 on.
- the first and the second hydraulic elements 15, 16 adjoin a common hydraulic chamber 17 and are operatively connected via the hydraulic fluid received in the hydraulic chamber 17.
- Sealing rings 22, 23 are provided for sealing the hydraulic chamber 17.
- one or more springs 24 are arranged in the hydraulic space 17, which press the first and the second hydraulic elements 15, 16 apart in the axial direction and thus hold the release bearing under a defined preloading force.
- the release device 7 has a contact surface 31 on the transmission side, via which it is connected to the housing 32 of the transmission.
- the contact surface 31 is designed as a separation point at which the clutch can be released from the transmission in the installed state.
- the gear-side contact surface is flat and runs in the radial direction.
- 1 also shows holding means for connecting the clutch and the transmission.
- the holding means have a first component 33 and a second component 34, the first component 33 being fixed to the housing 32 of the transmission and the second component 34 being firmly connected to the disengaging device 7.
- the first component 33 and the second component 34 are fixedly but releasably connected to one another via connecting means 35.
- the second component 34 is arranged radially on the inside and is radially enclosed by the first component 33.
- connection means 35 In order to enable the connection means 35 to be released when the coupling is installed, there are recesses in the coupling bell 36 37, through which, for example, connecting means 35 designed as screws are accessible and can be released.
- the connecting element 25 is designed as a latching element. Since the connecting element 25 is resilient, it is pressed by this spring force from a release position into a latching position. When assembling the clutch, the locking element can thereby be pressed under the spring force into the locking position, in which the connecting element engages behind the inner bearing part 13 of the release bearing 10.
- FIG. 1 shows a speed-adaptive vibration damper 29, only shown schematically, which is fixed to the flywheel 5 by means of connecting means, not shown.
- the separating point 31 in FIG. 2 is not designed as a flat, but as a stepped separating joint, as a result of which the disengaging device is kept centered relative to the transmission.
- the holding means consist of clamping means 37 which radially enclose the parting line.
- the clamping means 37 are formed from two half-shells which are clamped together by connecting elements, for example by screws.
- two holding arms 38, 39 are formed on the disengaging device 7, which extend outwards in the radial direction in opposite directions.
- connecting means 35 are provided on the holding arms 38, 39, which are in particular designed as screws and hold the release device 7 clamped to the housing 32.
- the connecting means 35 are arranged so that they extend substantially parallel to the axial direction of the shaft 4. In this way, a simple structure is achieved, the disengaging device 7 and the transmission being particularly light from one another can be separated by loosening the connecting means 35. The latter are easily accessible even when the clutch is installed.
- a further simplification of the assembly can be achieved in that the housing 32 of the transmission has at least one recess, which is arranged and designed such that the connecting means 35 are accessible for releasing the connecting means 35 in the installed state of the coupling.
