Definitions

  • the invention relates to a clutch disk with an axis of rotation for a friction clutch, a friction clutch with such a clutch disk for a drive train, a drive train with such a friction clutch, and a motor vehicle with such a drive train.
  • Clutch disks for example for a friction clutch of a motor vehicle, with a torsional vibration damper are known from the prior art.
  • a torsional vibration damper comprises a friction device, for example as a hysteresis element.
  • Such a friction device is set up to dissipate vibration energy, so that a more even torque transmission from an input side to an output side of a friction clutch is achieved.
  • the installation space for such a friction device in a clutch disc is very tight.
  • the plate spring tongues will be out of place during assembly and, for example, get into a riveting area. It is then not guaranteed that the disc spring is fully functional and / or the quality assurance in the assembly is complex.
  • the invention relates to a clutch disc with an axis of rotation for a friction clutch, having at least the following components: a torsion damper flange; a drive plate; a counter disk; an axial fastening device by means of which the drive disk and the counter disk are connected to one another axially and in a torque-rigid manner; a friction ring between the torsion damper flange and the drive plate or the counter plate; and a plate spring for exerting an axial force on the friction ring for frictional engagement.
  • the clutch disc is primarily characterized in that the friction ring is positioned in a predetermined manner by means of the axial fastening device and the disc spring is positioned in a predetermined manner by means of the friction ring.
  • the clutch disc proposed here is set up for conventional use in a friction clutch, that is to say for frictionally releasable Torque transmission in a friction package.
  • a friction package comprises at least one clutch disk and a pressure plate and a counterplate for each clutch disk, or in the case of a double clutch, for example, a common central plate instead of two counterplates.
  • the counter plate is also referred to as a flywheel (due to its additional function).
  • the counter-plate and the pressure plate are connected to one another in a rotationally fixed manner and to the input side in a torque-resistant manner, the clutch disc being connected to the output side in a torque-resistant manner.
  • the input side denotes the side via which a torque is introduced in a main operating state
  • the output side denotes the side via which a torque is queried in a main operating state.
  • reverse operation is possible or even an operating state that is the same or more frequent than a torque transmission from the input side to the output side.
  • the input side is connected in a torque-stiff manner, for example, to an engine shaft of a drive machine, for example to a combustion shaft of an internal combustion engine.
  • the output side is (then) connected to a transmission input shaft in a torque-resistant manner.
  • the pressure plate In order to press the clutch disc for frictional torque transmission between the pressure plate and the counter-plate, the pressure plate can be moved axially so that it can be pressed axially against the clutch disc.
  • the clutch disk has a friction surface which is arranged radially on the outside and which can be axially compressed between the counterplate and the pressure plate, so that a torque can be releasably transmitted in a frictionally engaged manner.
  • the friction surface is held by a drive plate, for example glued and / or riveted.
  • a counter-disk is provided, which is connected to the drive disk axially and in a torque-resistant manner by means of an axial fastening device.
  • the drive plate and the counter plate are also generally referred to below as the disks.
  • a torsion damper flange is damped and transmits torque with the Drive plate and the counter plate connected, for example by means of at least one, preferably a plurality of, damper spring (s).
  • a (first) friction ring is (permanently) axially frictionally pressed against the torsion damper flange, so that the torsional vibration energy is dissipatively withdrawn from the system in the form of friction (heat).
  • a predetermined frictional force is desired, that is, a predetermined axial pressure of the friction ring against the torsion damper flange, that is, a predetermined axial force is necessary to generate the frictional engagement.
  • This axial force is held by a structurally, so as a result of a set axial distance, axially pretensioned disc spring.
  • the plate spring is axially supported on the rear of the drive plate.
  • the plate spring is axially supported on the rear of the counter disk.
  • a further friction ring is provided between the torsion damper flange and the respective other disk (for example the counter disk), preferably without a further plate spring.
  • the disc spring In order to accommodate the disc spring in the mostly confined space in such a way that assembly is simple and the functionality of the mounted clutch disc is ensured, it is desirable for the disc spring to be positioned in a predetermined manner with tight positioning tolerances. At the same time, it is not desirable for the plate spring to be in frictional contact (at least in a region of the tilting movement) with an element of one of the disks and / or the axial fastening device.
  • the disc spring be positioned in a predetermined manner only indirectly via the axial fastening device.
  • the friction ring is positioned in a predetermined manner by means of at least one corresponding positioning receptacle directly above the axial fastening device, for example in a form-fitting manner.
  • the positioning receptacle is preferably set up in such a way that the friction ring is positioned in a predetermined manner with as little play as possible in the circumferential direction (with close tolerances). For example, contact between the positioning receptacle and a corresponding (positioning-effective) surface of the axial fastening device is permissible.
  • the disc spring is now positioned in a predetermined position directly above the friction ring. Thus, a positioning of the plate spring without direct contact and thus without (frictional) contact relative to the axial fastening device is positioned in a predetermined manner.
  • the plate spring is preferably positioned with a positive fit relative to the friction ring.
  • the axial fastening device is formed by at least one stepped bolt and the friction ring forms a through opening for each stepped bolt.
  • a stepped bolt here preferably used as a spacer bolt, has sections over its length with different diameters, so that the disks are axially and torque-rigidly fixed to one another, preferably a predetermined distance is set up between the driver disk and the counter disk, preferably by means of at least two shoulders in a form-fitting manner is set.
  • the end of the stepped bolts are deformed, for example riveted, for connection to the drive plate and the counter plate.
  • the counter disk and the driver disk are connected to one another in an axially and torque-resistant manner. If centering of the friction ring (and preferably also the plate spring) is to be achieved at the same time by means of the stepped bolts, it is advantageous if three or more stepped bolts are provided.
  • stepped bolts In one embodiment, in addition to the at least one stepped bolt, at least one further, for example axially aligned sheet-metal-formed element, which is formed from at least one of the disks and forms the axial fastening device together with the stepped bolt. In an alternative Embodiment, the axial fastening device is carried out free of, so without, bolts.
  • the friction ring is designed with such a radial extension that the friction ring with the at least one stepped bolt overlaps radially (and in the circumferential direction, that is, flat). As a result of this large radial expansion of the friction ring, it has great torsional rigidity.
  • a through opening is formed in the material of the friction ring for the at least one stepped bolt, preferably in each case. The through-opening is designed at least in the circumferential direction with as little play as possible on the (corresponding shank of the) stepped bolt, so that very precise positioning of the friction ring is achieved.
  • the through opening is preferably designed with a small amount of play radially on the outside and / or radially on the inside with respect to the stepped bolt.
  • the radial position, that is to say the centering, of the friction ring is thus achieved in a predetermined manner when the friction ring is mounted.
  • the friction ring preferably forms one, preferably the only, friction surface to the torsion damper flange radially outside of the at least one stepped bolt.
  • the disc spring is designed with the friction ring-side, ie front-side, bearing surface facing radially outward and the disk-side, ie rear-side, bearing surface radially inward.
  • the friction ring has at least one tab with an axial extension and the plate spring forms a corresponding tab receptacle for at least one of the tabs, the cup spring being positioned in a predetermined manner by means of the tab and the corresponding tab receptacle. So that the assembly of the clutch disc can be carried out easily and reliably, the disc spring must be securely (for example vibration-proof) positioned in a predetermined manner.
  • the tabs are in engagement with the corresponding tab receptacles with an axial extension.
  • the tabs are preferably integrated into the friction ring and / or the tab receptacles are integrated into the disk spring, particularly preferably (each) formed in one piece with the friction ring or with the disk spring.
  • a form-fitting connection is formed with the tab and the tab receptacle. This ensures that the disc spring does not shift during the assembly process. This ensures that the disc spring does not get into the later assembly area of the axial fastening device. This means that incorrect assembly with regard to the disc spring (and the friction ring) is ruled out.
  • the axial fastening device is a stepped bolt according to an embodiment of the previous description.
  • the number of tabs and tab receptacles of the axial fastening device preferably corresponds to, for example, five of the tabs and five of the (corresponding) tab receptacles with five stepped bolts.
