Definitions

  • the invention relates to a power transmission unit according to the preamble of claim 1.
  • a driver unit for power transmission units is known from EP 1 382 872 AI. Such a driver unit is used in particular, but not exclusively, for the drive or output connection of multi-plate clutch systems in double clutches.
  • the positive connection between the drive plate and the disk carrier is usually for assembly reasons and because of an economical production subject to play. hereby there are increased signs of wear, in particular by hammering in the connection between the driving plate and the disk carrier. Another disadvantage is an idle noise development due to the playful positive connection.
  • a generic power transmission unit is known.
  • a half-shell of a torsional vibration damper is axially connected to a further component of the power transmission unit.
  • a flat locking ring is provided which is disposed within a circlip and a hand, is supported on a groove wall and on the other hand on the half-shell and thus presses the half-shell axially firmly against the further component.
  • backlash reduction or noise reduction can be designed precisely.
  • the object of the present invention is to propose a power transmission unit in which at least two components are connected to one another axially without play.
  • the invention is based on the idea of replacing, at least in the axial connection of two components of a clutch assembly, the previously common flat circlip by a circlip which is corrugated and thus resilient, in particular in the circumferential direction.
  • a corrugated locking ring By using a corrugated locking ring, the components to be connected are preloaded against each other in the axial direction. Since the corrugated circlip can adapt to the available space within certain limits, a backlash-free axial connection is ensured.
  • the inventive design of the power transmission unit results in the provision of a backlash-free connection a variety of other advantages, such as easier logistics, less storage, and reduced costs.
  • the corrugated locking ring can be used for axially fixing a drive plate to a disk carrier.
  • a corrugated retaining ring for this purpose, an axial movement of the drive plate within the now partially non-positive connection to the disk carrier is avoided.
  • the axial preload prevents movement in the circumferential direction within a possibly existing play, because here too, due to frictional forces there is a non-positive connection for smaller torques. In this way, noise development during idling can be prevented.
  • the corrugated circlip should be designed so that the resulting preload is so large that the axial force always remains smaller than this preload due to the maximum circumferential bending moment. This is the only way to avoid “lifting" of the drive plate and thus also a relative movement in the axial direction. Furthermore, the static friction generated with the pretensioning force in the circumferential direction should be large enough to cause movement of the drive plate in the circumferential direction, especially at low torques when idling This reliably prevents noises such as idling rattling and also prevents wear at the connection point.
  • the driving plate is provided with external teeth and the disk carrier is provided with an internal toothing that is at least partially complementary to the external teeth of the driving disk. It makes sense, but not necessary, that the internal teeth and the external teeth engage behind, at least in sections, in the inserted state.
  • the resilient property of the corrugated circlip has the advantage that the dynamic load on the circlip groove made in the disk carrier is at least reduced.
  • FIG. 1 is a perspective view of a drive plate and an outer disk carrier in the unassembled state
  • FIG. 3 shows a schematic illustration of a section of a driver unit with a corrugated locking ring
  • 4 shows a detail of a multi-plate clutch with torsional vibration damper
  • Fig. 5 shows a detail of another embodiment of a multi-plate clutch
  • Fig. 6 shows a section of another embodiment of a multi-plate clutch.
  • FIG. 1 shows a driver unit 1 in a perspective and incomplete representation.
  • FIG. 1 shows no means for axially prestressing the driver disk 3.
  • Only a driver disk 3 is shown, and an outer disk carrier 2 is shown as an example.
  • the driver disk 3 is equipped with circumferential external teeth 4.
  • the outer disk carrier 2 has an internal toothing 5.
  • the outer disk carrier 2 has a slot-like recess 7 in the region of each tooth 6, each slot-like recess being penetrated by a tooth 8 of the external toothing 4 in the assembled state.
  • FIG. 2 A driver unit in the assembled state is indicated in FIG. 2, no means for axially prestressing the driver disk 3 being shown here either. It is clear that the drive plate 3 and the disk carrier 2 have a common axis of rotation 9 in the assembled state.
  • the positive connection between the driving disk 3 and the outer disk carrier 2 is formed by an external toothing 4 on the driving disk 3 and an internal toothing 5 on the disk carrier 2, the teeth 8 of the external toothing 4 engaging in slot-like recesses 7 in the disk carrier 2.
  • the external toothing 4 and the internal toothing 5 engage behind one another.
  • the corrugated non-positive connection is only to be understood as an example. In a much simpler embodiment, no internal toothing is provided and the external toothing 4 is received in recesses in the disk carrier 2.
  • FIG. 3 shows a schematic representation of a driver unit 1, consisting of a disk carrier 2 with outer disks, not shown, and a drive disk 3 on the drive side.
  • the driver disk 3 is non-positively connected to the outer disk carrier 2 on the circumferential side.
  • fen teeth 8 of the drive plate 3 in slot-like recesses 7 in the disk carrier 2.
  • the driver disk is supported in the axial direction at the end 10 of the slot-like recess 7 on the disk carrier 2.
  • On the opposite side is a circumferential corrugated circlip 12 for axial
  • the corrugated circlip 12 is circumferential and in turn is supported on the disk carrier 2 in a circlip groove 13.
  • the circlip groove 13 is circumferentially introduced in the disk carrier 2. 1 shows a locking ring groove 13 for receiving a conventional locking ring 15.
  • a bending moment M results from a radial force F R.
  • the radial force F R can be attributed, for example, to an incorrectly aligned installation of the power transmission unit in the drive train.
  • the bending moment M results in an axial force F a , on the basis of which the driving disk 3 would like to move in the axial direction.
  • the axial force F a is compensated with the help of the corrugated circlip for axial preload.
  • the axial tolerance compensation is also carried out by means of the corrugated locking ring 12.
  • the corrugated locking ring 12 is to be designed such that the axial force Fa is always smaller than the pretensioning force due to the bending moment M. This is the only way to prevent "lifting" of the driving plate 3.
  • FIG. 4 shows a multi-plate double clutch 16 known per se with a torsional vibration damper 17 also known per se.
  • a shell 19 of the torsional vibration damper 17 is fixed in the axial direction by means of a corrugated locking ring 18 on a housing part 20 of the multi-plate double clutch 16.
  • the corrugated circlip 12 is arranged in a circlip groove 13 which is circumferentially introduced in the housing part 20 and projects radially inwards beyond it.
  • the corrugated retaining ring 12 is axially supported on one side on a groove wall 18 of the retaining ring groove 13. With its opposite side, the corrugated locking ring 12 is supported axially on the outside of the shell 19 of the torsional vibration damper 17.
  • the shell 19 and the housing part 20 are in turn axially supported on a further housing part 21.
  • FIG. 5 shows a further embodiment of a multi-plate clutch 16 known per se. It is further shown that an outer disk carrier 22 is axially prestressed against a bowl-shaped housing part 23 by means of a corrugated locking ring 12. The corrugated locking ring 12 is supported on the one hand on a shoulder 24 of the housing part 23 and on the other hand on the plate carrier 22.
  • Disc carrier engages radially in a tooth-like manner in axially extending recesses 25 of the housing part 23. Through the undulated retaining ring 23, the disk carrier 22 is axially biased against the outer housing part 23.
  • FIG. 6 shows a section of a further embodiment of a multi-plate double clutch 16 known per se.
  • a closure cover 26 is axially biased against a disk carrier 22 by means of a corrugated retaining ring 12 arranged in a retaining ring groove 13.
  • the closure cover 26 engages radially in axially extending recesses 27 in the disk carrier 22 distributed over the circumference.
  • the corrugated locking ring 12 is supported axially on the one hand on a groove wall 18 and on the other hand on the closure cover 26, as a result of which the closure cover 26 axially against a bottom 28 of the recesses. gen 27 is pressed.
