- the invention also relates to a drive train with a main drive shaft and with a torsional vibration damper, which are connected to each other by means of a non-destructive releasable and / or a self-connecting connection about a common axis of rotation, and with a disposed between the main drive shaft and the torsional vibration damper, which is sealed to the drive train by means of a seal.
- the invention furthermore relates to a drive train for a motor vehicle having a drive shaft, an output-side transmission and a clutch arranged between drive shaft and transmission and a vibration damper arranged on the drive side of the clutch, which has a damper shaft on the drive side.
- drive shaft is operatively connected via a flexplate.
- Such drive trains are implemented, for example, by the torque transmission device, which is described in the published patent application DE 10 2005 025 773 A1.
- the drive train between a drive unit and a transmission comprises at least one clutch device and at least one vibration damper device.
- the torque transmission device is characterized in that both an input part and an output part of the vibration damping Fung device or an input part of the coupling device are mounted or supported in the radial direction on a coupling housing portion of the coupling device. This makes it possible to optimize generic torque transmission devices with respect to their space, in particular, the drive train is simple and inexpensive to produce.
- EP 1 496 287 A1 and EP 1 496 288 A1 also disclose such a drive train, in which, however, a flexplate is provided on the output side of a flywheel and on the drive side of a torsional vibration damper in order to be able to absorb axial oscillations.
- the object of the invention is achieved on the one hand by a drive train with a main drive shaft and a torsional vibration damper, wherein the main drive shaft and the torsional vibration damper essentially rotate about a common axis of rotation and are connected to one another via a connection, whereby the connection can be disengaged indestructibly and / or is self-connecting, wherein axially between the main drive shaft and the torsional vibration damper, a wall is arranged, which is sealed to the drive train by a seal, and wherein the drive train is characterized in that the connection radially to the common axis of rotation farther away ange- is as the torsion damper wall seal and as the main drive shaft in the region of the seal.
- connection between the main drive shaft of the drive train and the torsional vibration damper of the drive train is arranged radially farther to the common axis of rotation than, in particular, the seal of the wall between the main drive shaft and the torsional vibration damper, so that vibrations of the system that result, in particular, from the torsional vibration damper only to be found behind the connection and behind the seal, do not stress the connection so much, since the connection forces also apply radially further out.
- the compound structurally larger and thus structurally designed to be stronger than known connections between a main drive shaft and a torsional vibration damper since the compound of the invention can be further constructed radially outboard with a larger scope.
- the present connection advantageously also does not have to be as delicate as the connection of the known torque transmission device.
- the connection it is not necessary in this context that the connection must meet very high manufacturing requirements in order to ensure a reliable connection permanently.
- the connection since the connection is located radially further away than the seal, it extends at a substantially greater radius about the common axis of rotation. This allows each other Corresponding and joined together connecting elements of the present connection are much stronger or coarser and thus executed and manufactured with lower tolerance requirements.
- the connection forces are radially outward, so that in particular vibrations can show much less harmful effects.
- connection any connection means are detected, which are adapted to non-positively, positively or otherwise to connect a main drive shaft or fixed to the main drive shaft components in particular with a torsional vibration damper or with components of the torsional vibration damper that a intended torque can be transmitted.
- any sealing means are described, by means of which an opening in a wall which is arranged between a main drive shaft and a torsional vibration damper, with respect to rotating components of a drive train, in particular the main drive shaft, which penetrate the wall or are stored on this, in particular against the escape of oil or other liquids and / or against the ingress of dirt or the like can be sealed.
- a seal is in connection with the invention of a wall seal.
- the object of the invention cumulatively or alternatively also by a drive train with a main drive shaft and with a torsional vibration damper, which are connected by means of a non-destructive releasable and / or a self-connecting connection about a common axis of rotation with each other, and with a between the Main drive shaft and the torsional vibration damper disposed wall, which is sealed to the drive train by means of a seal solved, wherein the drive train is characterized in that the seal is arranged axially on the drive side with respect to the compound.
- connection By the axial drive side arrangement of the seal with respect to the connection, it is also possible to form the connection with a much stronger structure, so that in the present case also the requirements for production and quality of the connection is lower than in the prior art in generic torque transmission devices or drive strands required for this purpose. This is in particular because then much more space is available for the connection, since the seal should naturally be on the smallest possible radius to wear as little as possible or as little adversely affect the drive train by friction or tilting moments.
- the object of the invention also by a drive train with a main drive shaft and with a torsional vibration damper, which are connected by means of a non-destructive releasable and / or a self-connecting connection about a common axis of rotation with each other, and with a between the main drive shaft and the torsional vibration damper disposed wall, which is sealed to the drive train by means of a seal solved, and the drive train is characterized in that the seal is axially disposed on the transmission side with respect to the compound.
- the structure of the drive train in the region of the seal advantageously also simplifies, so that it can be arranged on a very small radius.
- connection can be made simpler in itself and, in particular, this also leaves sufficient space for the wall and the seal in order to draw the wall radially inward very far and, accordingly, to arrange the seal radially very far inwards.
- An embodiment variant provides that the present drive train has a mass flywheel, which is fixedly mounted on the drive side of the connection to the main drive shaft. Due to the inertia of the mass flywheel, a part of the disturbances, which run through the drive train from a drive, are intercepted before the connection, so that the connection accordingly less burdened and therefore less critical can be interpreted.
- mass flywheels are usually formed relatively solid and structurally relatively large, these manufacturing technology structurally and structurally can be easily modified so that they form at least one component of the presently described compound or provide.
- a preferred embodiment comprising a mass flywheel then also provides that the connection is provided on the drive side directly by the mass flywheel.
- a force and / or torque transmission from a main drive shaft to a torsional vibration damper is advantageously realized, since the present compound structurally simple radially to the common axis of rotation on a mass flywheel further away than the seal of the wall can be arranged.
- the drive train has a connecting member, which is arranged on the damper side of the connection between this and the torsional vibration damper and on which the present seal seals the torsional vibration damper in the region of the wall, as by means of such a connecting member a structurally particularly simple configured seal receptacle can be provided.
- the wall seal of the wall lies, for example, between an oil-free drive side and an oil-filled transmission or torsional vibration damper side on a connection member of the connection, the drive side can be separated from the damper side in the region of the connection without the damper side having to be dismantled further for this purpose.
- a filled with oil damper side need not be emptied when the connection between the drive side and damper side is disconnected, since the damper side link remains on the damper side and there sealingly abuts the wall seal.
- target mounting surface describes here an area along which the drive train, in particular also housing components of adjacent drive train areas, is joined together.
- connection also includes a drive-side link, which on the drive side fixed to the flywheel and / or the main drive shaft, such as a crankshaft connected and drive side of the connection with the seal, the initial assembly is particularly simple, since a possibly damper side existing oil space can be sealed before assembly of the damper side by means of the seal between a wall and a drive-side connecting member of the compound and a particularly large amount of mounting space is available.
- connection is arranged on a larger circumference than the seal on the output side of the seal.
- Such an arrangement makes it possible in particular, in a preferred embodiment, to arrange the connection in an oil space, whereby the connection area is further relieved because of the damping effect of the oil.
- the drive train has a ring gear which is fastened radially to the axis of rotation, in particular on the outer edge of a mass flywheel, it is possible compactly to provide a drive train in which the mass flywheel with further components, such as a starter of a starter Combustion engine, comb can, while at the same time the mass of the ring gear for vibration damping - and thus contribute to an advantageous discharge of the compound.
- the object of the invention is also independent of the other features of the present invention of a powertrain for a motor vehicle with a Antriebswel- Ie, with a driven side gear and arranged between a drive shaft and transmission clutch and arranged on the drive side of the clutch Schwin - Damper, the drive side having a damper shaft, which is operatively connected to the drive shaft via a connecting plate, solved, the connecting plate on the drive side radially outside with a rigid drive disc is non-destructively releasably connected.
- Such a drive train has the advantage that the mass of the rigid drive pulley at one of the drive pulley, the connecting plate and the damping shaft with its own and subsequent moment of inertia already forms a good vibration damper, a part of the damper shaft or in
- the connection between the connecting plate and damper shaft occurring vibrations attenuates outstanding that a relatively large mass or a relatively large moment of inertia already primary side, ie drive side, the connecting plate, which forms the oscillating and damping system of this vibration damper arrangement is arranged.
- flexplate and "connectingplate” signify plate-shaped, torque-transmitting assemblies which are axially softer, in particular axially softer, by an order of magnitude than adjacent, torque-transmitting assemblies.
- “flexplates” or “connecting plates” are almost membranous to the adjacent assemblies, which may well have grooves, depressions, recesses or other structural measures, in particular to make them axially even softer than this material choice and strength already allow.
- Such assemblies are also referred to as bending / tumbling soft disc.
- DE 102005 025 773 A1 further discloses, on the one hand, a welded connection between drive shaft and damper shaft and, on the other hand, just as in Offenlegungsschrift DE 10243 279 A1, a form-locking connection.
- measures are provided by which the form fit after assembly is taken all game, since such a game is necessary for the assembly, so that the two modules can be plugged easily on each other, and since the backlash of this particular Significance is because the connection between the drive shaft and damper shaft is arranged on the drive side of the vibration damper and thus exposed to extreme vibration loads.
- the connecting plate on the drive side radially operatively connected to a rigid drive disk
- the connecting plate can drive side even solve a drive train, if the drive side and transmission side or damper side are already mounted together, since such an external connection also remains relatively easy to access after installation. This is especially true if the gearbox or damper side an oil chamber is provided, which thus can remain closed even when disassembling the Connectingplate from the drive side.
- EP 1 496 287 A1 and EP 1 496 288 A1 which disclose a rivet connection which can only be detached by destruction between the flexplate disclosed therein and a more rigid drive disk
- the radially outward detachability of the connection between connecting plate and drive disk makes it possible
- Another solution proposes a drive train for a motor vehicle with a drive shaft, with a driven side gear and arranged between the drive shaft and gearbox clutch and a drive side of the clutch arranged vibration damper, the drive side has a damper shaft, which with the drive shaft is operatively connected via a connecting plate, wherein the connection between the damper shaft and the connecting plate comprises a press connection between a damper-side connection group and a connection plate-side connection group.
- a press connection which in the present context is defined by the fact that the two connected connection groups are connected to one another by internal forces or braces and not by bracing with further assemblies, such as screws, advantageously enables a very simple to manufacture and stable connection, which can be made sufficiently secure especially in vibrations.
- the press connection is also a detachable connection, so that the assembly work structurally easier.
- the press connection described here can be used as detachable connections, for example, pressed spline connections, pressed conical joints or hydraulic clamping elements that are radially compressed hydraulically, are used.
- the solubility is not mandatory, because in combination with detachable connections elsewhere disassembly can be made possible, so that the interference fit can also be very firmly selected.
- a drive train for a motor vehicle with a drive shaft in particular also arranged according to one of the above-described feature combinations, with a driven-side gear and with a between the drive shaft and transmission
- the drive side has a damper shaft which is operatively connected to the drive shaft via a connecting tingplate proposed, wherein the connection between damper shaft and
- Connectingplate comprises an axial frictional engagement between a damper-side connection group and a connecting plate-side connection group.
- axial frictional engagement between two elements means that these two elements act in a frictional engagement with one another in the axial direction, without the additional assemblies acting on each other, in particular a screw which connects the two assemblies together.
- the axial frictional engagement between the damper-side connection group and the connection plate-side connection group is structurally advantageously very simple to implement and moreover requires, above all, very few assemblies.
- the two pressed or interconnected via the axial frictional engagement assemblies can hereby be pressed together via a conical connection surface with each other, as long as the tension is realized by internal forces or by internal tension, which requires that the corresponding cone angle are chosen relatively small.
- the drive train is characterized in that the connection between the damper shaft and the connecting plate comprises a cylindrical connection area between a damper-side connection group and a connecting plate-side connection group.
- the cylindrical connection area is pressed together by the cylindrical connection area being distended or shrunk onto the damper-side connection group.
- the cylindrical connection region can be distended or shrunk onto the connection plate-side connection group.
- a connection between damper shaft and connecting plate which comprises a cylindrical connecting region between a damper-side connection group and connecting plate-side connection group, enables a particularly simple construction of the connection, which ultimately also includes, for example, a press connection, a material connection, such as a welded connection, or even a screw or a friction could be closed very easily and reliable.
- the cylindrical connecting region ensures a large contact surface in the axial direction, so that correspondingly large axial connecting forces can be applied by the connecting elements.
- the connection can be formed in particular vibration-resistant. This applies in particular to conical configurations in which even a slight axial displacement can already lead to a considerable reduction of the connection surface or of the contact between the connection groups.
- the present invention is particularly suitable for dual-clutch transmissions, in particular when the actual torsional vibration damper is to be accommodated in the housing of the transmission, so that a housing passage, which in particular is disposed radially far inward should, seems to be an advantage.

- rattling noises caused by high-frequency oscillations with a low amplitude can be specifically avoided by the advantageous means for generating a force which counteracts a reduction of the distance between the rotational angle between the drive shaft and the damper shaft.
- the required forces can act in particular even at extremely low angles of rotation, which is just not possible for springs with a linearly dependent on the angle of rotation characteristic.

- mechanical energy converters By means of such mechanical energy converters, kinetic energy can advantageously be converted into heat energy, as a result of which the compound described above obtains particularly good damping properties.
- An advantageous embodiment provides that the mechanical energy converter is connected via a positive connection with the drive shaft and / or with the damper shaft, the former being implemented in particular in complex energy converters. Is there a positive connection between the mechanical energy converter and other components of the drive train, it is excluded that due to the mechanical energy converter game in the connection between a drive-side main drive shaft and a damper shaft, for example, a torsional vibration damper is present.

- the drive-side connecting member 123 is in turn pre-centered with a centering surface 131 on the mass flywheel 107.
- the provision of a centering surface 131 on a connecting device 122, in particular on the drive-side connecting member 123, is advantageous even without the other features of the present invention, as this significantly facilitates the connection of a drive side and a transmission or damper side 104 of the drive train 101.
- the drive side 103 and the transmission side 104 can be loosely connected to each other, so that assembly and disassembly is much easier.
- the drive-side connecting member 123 is connected to a connecting plate 132, which is braced by means of a sleeve-screw arrangement 133 with the mass flywheel 107.
- the drive-side link 123 is firmly but releasably attached to the mass flywheel 107.

This is possible since the connecting plate 132 in the drive train 101 is arranged closer to the torsional vibration damper 116 than is usual in the prior art.
- the connecting plate 132 is fastened to the mass flywheel 107 by means of the radially far outer sleeve screw arrangement 133, already the masses of the mass flywheel 107 and the mass of the connecting plate 132 already provide a first good vibration damper, which covers a large part of the connection 122A between the drive-side connecting member 123 and the damper-side connecting member 130 vibrations dampens excellent in that already a relatively large mass or a relatively large moment of inertia is already arranged on the drive side of the connecting plate 132.

- a compound with smooth conical or cylindrical surfaces can be selected, if this in particular allow the expected moments.
- a serrated shaft has the advantage that a hub corresponding to it can be made relatively thin-walled. Nevertheless, high torques can be transmitted with it.
- the centering surface 131 of the drive-side connecting member 123 can be correspondingly provided with a smaller diameter with respect to its outer circumference. This makes it again possible to make the outer circumference of the centering surface 131 smaller than the outer circumference of the crankshaft 106, so that the centering surface 131 can be placed within the crankshaft diameter. This leaves the Drive train 101 overall very compact build. On the other hand, it is understood that in this embodiment can be dispensed with such a centering.
