Definitions

  • the invention relates to a clutch device with a first partial clutch comprising a first outer disk carrier, a first inner disk carrier and a first disk pack arranged on these, which can be compressed via a first pressure element that can be moved against a first restoring element, and with egg ner radially inside the first partial clutch arranged second partial clutch to summarize a second outer disk carrier, wherein the first and the secondêtla mellonia are rotatably coupled to each other via a radially extending connecting element.
  • Such a coupling device is used in a known manner for the temporary manufacture of a torque-transmitted frictional connection between a drive shaft of an internal combustion engine or an electric motor and an output shaft running to a transmission.
  • a coupling device In addition to designing such a coupling device as a single coupling, it is also known to design a coupling device as a double coupling.
  • Such a coupling device comprises a first partial clutch and a second partial clutch, each of which has a corresponding disk pack with outer and inner disks as well as an outer disk carrier and an inner disk carrier, each disk pack being able to be pressed together separately via a separate pressure element, usually a pressure pot.
  • the two outer plate carriers are connected to the input shaft with which the torque is introduced, while the two inner plate carriers are connected to separate output shafts that lead to separate gear stages that can be switched separately via the individual partial clutches.
  • a force or frictional connection is achieved so that torques introduced by the drive shaft via the respective outer disk carrier are passed through the respective disk pack to the respective inner disk carrier and via this to the respective output shaft to the transmission can.
  • the structure of the coupling device described above is well known. As described, the torque-transmitting frictional engagement is achieved by compressing the or each disk pack. If this is no longer necessary, the respective compressed lamella pack must be opened again, for which purpose it must be relieved.
  • the pressure element is usually movable to compress the lamellas pack against a restoring element that builds up a restoring force that pushes the pressure element back into the starting position when it is relieved via the upstream hydraulic Actuate transmission arrangement.
  • a support ring is provided for axial support or support of the return element, which is axially attached to the connecting element via the the two outer plate carriers of the partial clutches are non-rotatably connected to one another.
  • the annular restoring element ie the Tel lerfeder
  • the pressure element ie the pressure pot
  • this support ring has to bridge a certain axial length between its support plane on the connecting element and its support plane for the restoring element.
  • the support ring Since the support ring is a separate component, it has to be mounted separately, which makes the manufacture and assembly of the coupling device more complex, and of course the support ring must also be kept as a separate element.
  • the invention is therefore based on the problem of specifying a coupling device which is improved over this.
  • a coupling device of the type mentioned at the outset that several axially extending projections on the connecting element, on which the connecting element supported first restoring element is either axially supported or radially centered, are provided.
  • a plurality of axially extending projections are integrally formed on the connecting element, which, since eintei lig with the connecting element, can either serve to axially support the restoring element, ie can replace the support ring described above in its func tion and the axial Support of the first restoring element of the first partial clutch can be used.
  • the coupling device is constructed radially, which means that the first partial coupling is located radially further outward than the second partial coupling.
  • corresponding openings in the circumferential direction are formed in different radial planes, which are penetrated by corresponding coupling elements of the first outer disk carrier located further out and by corresponding coupling elements of the second outer disk carrier located radially further inside.
  • These coupling elements can also be referred to as axially extending fingers.
  • the projections are formed by axially bent element sections from the openings through which the coupling elements of the second outer disk carrier extend.
  • connection element is a stamped sheet metal component whose shape and openings are formed in a corresponding punching process. According to the invention, when punching, the openings that are axiallyteurgrif fen by the Kop pel elements or fingers of the second outer disk carrier are not completely punched out and the punched-out element sections are thrown ver. Much more, these element sections remain an integral part of the kausele Mentes and are only axially bent to form the projections. As a result, an otherwise discarded element section of the connecting element is used to form the protrusion, with the punching and axial deflection being able to take place in one operation.
  • the restoring element can be axially supported on the projections before, the bearing plane being given in the region of the inner circumference of the annular restoring element, which extends from the projections ra dial further outwards.

  • the pressure element for example the pressure pot, axially extending coupling elements, again for example in the form of axial fingers, are formed, and a short, axially extending edge bend can also be provided to stiffen the edge area.
  • the restoring element is now radially centered on this edge area or the coupling elements.
  • the projections are not used for axial support, but only for radial centering of the restoring element supported axially on the connecting element, viewed radially, within the area delimited by the projections distributed in the circumferential direction.
  • a bearing section can be provided on the connecting element on which the remindstellele element is axially supported, the projections radially closing on the bearing section.
