    The invention relates to a drive unit with an electric machine according to the preamble of claim 1.
    Drive units with an electric machine are used, for example, in vehicles, especially watercraft, with hybrid drive. Thus, vehicles are already known from the prior art, in which a hybrid drive is used which has an internal combustion engine and an electric machine.
    From WO 2006/034520 a motor vehicle is known, in which a hybrid drive is used, which consists of an internal combustion engine and two electric machines. The internal combustion engine and the electric machines are arranged inside the motor vehicle such that a center axis of an output shaft of the internal combustion engine is coaxial with a center axis of an output shaft of the respective electric machine.
    Such an arrangement of the internal combustion engine and the electric machine has the disadvantage that the hybrid drive is formed in the longitudinal direction very large or relatively elongated. This is particularly disadvantageous because in vehicles often only a limited installation space is available.
    The object of the invention is to provide a drive unit which does not have at least the aforementioned disadvantage.
    The object is solved by the subject matter of claim 1. Advantageous embodiments of the invention are the subject of the dependent claims. N2011 / 26300 P.005 / 036 30/09/2011 13:27 No .: R102 25 13:24:46 30-09-2011 6/36 • · * * Φ ··· Φ • φφφ η «♦ ·· • Μ · -2-
    According to the invention, a drive unit is provided with an electric machine having an output shaft and a clutch unit having at least one clutch shaft. The coupling unit is coupled to the output shaft of the electric machine and coupled via the clutch shaft with an output shaft of an internal combustion engine. In this case, the output shaft and clutch shaft are arranged such that a central axis of the output shaft of the electric machine is laterally or radially offset from a central axis of the clutch shaft.
    The offset or juxtaposed arrangement of the output shaft of the electric machine and the coupling shaft has the advantage that the drive unit with respect to the longitudinal direction is narrow or relatively short. Thus, a hybrid drive formed from the drive unit and the internal combustion engine can in principle be made narrower or shorter with respect to the longitudinal axis of the crankshaft of the internal combustion engine than the hybrid drive known from the prior art.
    For the purposes of the invention is understood as an offset arrangement of the central axis of the output shaft of the electric machine and the central axis of the clutch shaft, an arrangement in which the output shaft of the electric machine and the clutch shaft are not formed coaxially. The central axis of the output shaft of the electric machine can be offset parallel to the central axis of the clutch shaft. Of course, arrangements of the output shaft of the electric machine and the clutch shaft are possible in which the central axes are not parallel to each other. In these embodiments, it must be ensured that a coupling of the output shaft of the electric machine with the coupling unit is possible.
    The output shaft of the electric machine can be offset arbitrarily to KupplungsweHe. Thus, it is possible that the central axis of the output shaft of the electric machine with respect to the central axis of the coupling shaft in a stimseiti-view of the drive unit, ie in the direction of the central axes, is offset in the horizontal and / or vertical direction.

    As a clutch shaft is understood within the meaning of the invention for a while, which can be coupled to the output shaft of an internal combustion engine, in particular a crankshaft. Of course, the coupling shaft is also understood to mean a shaft which is formed in one piece with the output shaft of the internal combustion engine and projects into the drive unit, in particular into a housing of the drive unit. Furthermore, in the sense of the invention, the direction of the drive unit is understood to be the direction which is essentially parallel to the central axis of the output shaft of the internal combustion engine.
    The clutch shaft may be arranged such that it is coaxial with the output shaft of Veib internal combustion engine and / or coaxially to an input shaft of a transmission, in particular a gearbox is formed, a coaxial arrangement of the clutch shaft with respect to the output shaft of the internal combustion engine and / or the input shaft of the transmission of course when the drive unit is attached to the internal combustion engine or the transmission to the drive unit.
    In a preferred embodiment, the coupling of the electric machine with the internal combustion engine via a spur gear can take place. More specifically, the coupling can be made such that a gear of the output shaft of the electric machine meshes with a clutch gear of the clutch unit. Alternatively, at least one idler gear meshing with the two gears may be provided between the gear and the clutch gear of the clutch unit connected to the output shaft of the electric machine. In providing plural idler gears, an idler gear may be used instead of the clutch gear and / or gear of the drive unit mesh with another idler gear.
    In this case, the distance between the central axis of the electric machine and the central axis of the coupling shaft can be selected to be greater, the larger the intermediate gear used. Alternatively or additionally, it is possible for the gear wheel mounted on the output shaft of the electric machine and the clutch gear to be respectively detachable from the output shaft or clutch N2011 / 26300 30/09/2011 13:28

As a result, a coupling between the electric machine and the coupling unit can be ensured independently of the distance between these two components by appropriate choice of the diameter of the mounted on the output shaft gear and / or clutch gear. Consequently, it is ensured that regardless of the position of the electric machine on the housing of the drive unit, there is a coupling of this with the coupling unit.
    The position of the electric machine largely depends on the space provided by the internal combustion engine, which can be located at different locations in different internal combustion engines. Thus, it is made possible by the intermediate gear and / or the removable gear or clutch gear in a simple manner that without significant structural changes of the drive unit, this can be used in different internal combustion engines.
    Of course, the coupling of the internal combustion engine with the electric machine instead of the spur gear in other ways, such as by belts, sprockets, etc., take place.
    The clutch shaft and / or the output shaft of the electric machine can be coupled via a gear coupling means of the Kupptungseinheit with the input shaft of a transmission, in particular a gearbox. The gear coupling means may be connected to the clutch gear and comprise a cavity in which the input shaft of the transmission is rotatably connected to the gear coupling means. Thus, it is ensured in a simple manner that a rotational movement of the output shaft of the electric machine and / or the output shaft of the internal combustion engine is transmitted to the input shaft of the transmission.
    In a preferred embodiment, the coupling unit may have a coupling means, in particular a multi-disc clutch, for coupling or decoupling the internal combustion engine from the electric machine. The coupling agent can be between the clutch shaft and the output shaft of the electric M2011I2B300 30/09/2011 13:29

In particular, the Kuppiungsmittel may be provided between the clutch shaft and the clutch gear of the clutch unit and connected thereto. In this case, the coupling means is used for coupling or decoupling the coupling shaft with or from the clutch gear.
    The Kuppiungsmittel can be designed such that it builds a Bewegungsungskoppiung the internal combustion engine with the electric machine in the idle state In particular, the Kuppiungsmittel, which is provided for demand-coupling and decoupling of the internal combustion engine relative to the electric machine, designed such that the motion-coupling active state between the Internal combustion engine and the electric machine during the idle state of the coupling means vorfiegt. This can be ensured by, for example, holding at least one clamping means, in particular a spring assembly, the coupling means in the coupled state. In particular, it is expedient if the coupling unit comprises at least one clamping means, in particular a spring assembly whose resilient bias constantly urges the Kupplungsmittei in the actuated active state in which the internal combustion engine, the output shaft of the electric machine and a downstream gear coupling means of the drive unit with respect to rotational movements and torque transmissions coupled are.
    Due to the above-mentioned motion coupling, the output shaft of the electric machine rotates due to a rotational movement of the output shaft of the internal combustion engine even when the electric machine is turned off The output shaft or the rotor of the electric machine is additionally used as a flywheel for the internal combustion engine whereby the dimension or Dimensioning of the flywheel of the internal combustion engine, in particular the flywheel on the crank shaft, can be reduced. Another advantage is that the spring-elastic Spannmittei, in particular by a spring pact, no electrical energy is required to a drive connection from the Verbrennungskraflmaschine on the drive train of a vehicle, in particular to the drive means of a water- N2011 / 26300 30/09/2011 13:30 No .: RI02 P.009 / 036 13:27:40 30-09-2011 10/36 25 such as a ship propeller, to achieve. This makes it possible, even if the stored on board, electrical drive energy is consumed or is no longer sufficient to, for example, to reach the destination or port to be able to move solely with the drive power of the internal combustion engine. As a result, the reliability and reliability and availability of Fortbewegungsmöglichkeit is increased.
    The coupling means may be transitioned from a coupled state to an uncoupled state by actuation of a switching means coupled to the coupling means. Upon actuation of the switching means and thus the coupling means is no motion coupling between the internal combustion engine and the electric machine. That is, the internal combustion engine and the electric machine can be decoupled from each other by actively operating the switch means with respect to rotational movements as needed. It should be noted that a movement coupling or rotational movement connection between the electric machine and a downstream gear coupling means of the drive unit remains to be maintained in particular a fixed or unmissable motion coupling between the output shaft of the electric machine and the output side gear coupling means of the drive unit is formed, preferably by an intermediate The corresponding gear coupling means is designed for rotary motion coupling with a shift or marine gear and thus for transmitting the drive energy to the drive train of a vehicle, in particular a watercraft provided. Thus, the internal combustion engine by means of the coupling unit or via transfer of Kuppiungsmittels in the decoupled state when needed or requirement from the fixed or permanent drive network between the electric machine and gear coupling means wegschaltbar.
    The switching means may comprise a lever and a cam which is rotatably connected to the lever. Furthermore, the switching means may comprise a fork-shaped transmission means for transmitting a switching movement to the coupling means N2011 / 263Q0 30/09/2011 13:30

In particular, the transfer means is designed in such a way that, when deflected as a result of the cam movement, it rotates about an axis of rotation. In a deflection of the fork-shaped Übertragungsmitteis is exerted by this a force on the coupling means, which transfers this in the uncoupled or released position.
    The actuation of the lever of the switching means can be done electrically by means of an electrically driven actuator and / or manually. For example, manual operation requires 500N as a manual actuation force to translate the coupling means to a decoupled position. The possible manual operation of the switching means has the advantage that, especially in the marine sector, required manual emergency decoupling of Verbrennungskraftma-schirre of the electric machine is possible. In particular, can be done by this electric or electric motor, if necessary, but also purely manually operable switching means manual emergency decoupling of the internal combustion engine from the electric machine, so that in case of failure of the internal combustion engine driven purely electrically, in particular can be continued. Conversely, in the event of a fault in the electric drive train, for example due to depleted or almost depleted electrical energy stores, locomotion can only be achieved by means of the drive power of the internal combustion engine, which is of considerable advantage, particularly in the case of watercraft, or is relevant in terms of safety
    According to an expedient embodiment is provided, the electric actuator for the switching means as a servomotor, in particular as an electric motor with a spindle gear auszufQhran. A linearly adjustable spindle nut of the servomotor can be motion coupled to mild switching means. Furthermore, a manually releasable coupling connection, for example a bolt connection can be formed with splint securing, by means of which the switching means can be disconnected, if need be, disconnected from the electric actuator, in particular manually and without tools. Furthermore, it can be provided that the switching means by means of 30/09/2011 13:31

    In a preferred embodiment, the drive unit may have a housing into which the output shaft of the electric machine and / or the coupling shaft at least partially protrude. The housing may be connected to an internal combustion engine housing. Consequently, the drive unit is designed as a separate module with respect to the internal combustion engine and can be easily connected to this, in particular screwed.
    The electric machine, which may preferably be arranged outside the housing of the drive unit, may be carried by the housing of the drive unit. In particular, by supporting the part of the output shaft which penetrates into the housing, in particular of the gear wheel mounted on the output shaft, the electrical machine can be supported exclusively by the housing of the drive unit. In addition, the electric machine, in particular the housing or the stator of the electric machine, is rigidly connected to the housing of the drive unit. The electric machine is thus preferably mounted load-bearing exclusively on the housing of the drive unit. The electric machine is thus not supported relative to surrounding vehicle or frame cells or against Gehäuseabschnitlen the internal combustion engine, but is almost from the housing of the load-bearing drive unit. Alternatively, it would also be possible for the electrical machine to be arranged completely inside the housing of the drive unit.
    The electric machine can be arranged in a construction space that forms between the housing of the drive unit and the internal combustion engine housing. To make this easier, a recess for receiving the electric machine can be provided in the drive housing. The space is designed so that the electric machine in this der- N2011 / 26300 30/09/2011 13:32

In particular, the electric machine can be arranged in the space such that a circumferential surface of the housing of the electric machine is flush with the corresponding peripheral surface of the internal combustion engine housing.
    In a preferred embodiment, the housing of the drive unit may have two housing sections. The bearing of the output shaft of the electric machine and / or the intermediate gear and / or the coupling unit, in particular the coupling shaft, in the housing can be made such that a bearing are mounted in a housing portion and another bearing in another housing portion. Such a design of the housing allows easy mounting of the components of the drive unit. The bearings may be radial bearings, in particular radial ball bearings. Of course, other types of bearings are suitable for storing the aforementioned components.
    The drive unit and the internal combustion engine together form a hybrid drive unit. The drive unit or the hybrid drive unit can be used in a vehicle, in particular a watercraft.

    The drive unit 1 shown in FIG. 1 has a housing 10 and an electrical machine 11. The housing 10 of the drive unit 1 is connected to an internal combustion engine housing 20 of an internal combustion engine 2. The drive unit 1 or its housing 10 has an indentation 12 on its side facing the engine 2. The electric machine 11 is provided with respect to the longitudinal direction of the internal combustion engine 2 or in relation to the longitudinal axis of the crankshaft of the internal combustion engine 2 between the housing 10 of the drive unit 1 and the internal combustion engine 2. More specifically, the electric machine 111n of the recess 12 is arranged and fixedly connected to the housing 10 of the drive unit 1. From the housing 10 of the drive unit 1 protrudes a lift 50 of a switching means 5 shown in FIG.

The coupling unit 3 has a coupling shaft 30 which can be connected to an output shaft, not shown in the figures, of the internal combustion engine 2.

    Clutch world 30 has at Rirem the internal combustion engine 2 opposite end on a cavity into which the transmission coupling means 32 shown in Figure 3 penetrates Furthermore, the coupling shaft 30 carries a coupling means 31, which is designed as a multi-plate clutch, and at least one resilient clamping means, in particular a spring assembly 33rd The coupling means 31 is carried by the coupling shaft 30. Furthermore, the coupling means 31 is connected to a clutch gear 39 shown in FIG. The spring assembly 33 is arranged in the radial direction of a central axis K of the coupling shaft 30 between the coupling shaft 30 and a sleeve-shaped Kraftübertragungsmittei 38. Seen in the axial direction, the spring assembly 33 is disposed between a bearing 37 of the Kupptungswelle 30 and a projection 380 of the power transmission means 38. In this case, the arrangement of the spring assembly 33 in the coupling unit 3 is seen in the axial direction such that the frictionally acting Kuppkingsmittel 31, in particular a package of disc-shaped friction plates, is biased.
    The amount of bias can be adjusted via the bearing 37 by at least one provided on the Kupptungswelle 30 shim 34. An axial displacement of the at least one adjusting disk 34 in a direction away from the spring assembly 33 is prevented by a securing ring 35. The power transmission means 38 is axially displaceable along a central axis K of the coupling shaft 30 and has a flange 381 which can be brought into contact with the coupling means 31, in particular with the multi-plate clutch. Due to the bias of the spring assembly 33, and thus the application of force to the force transmitting means 38 via the projection 380, the flange 381 presses against the coupling means 31, so that the coupling means 31 is in a coupled state or constantly urged into the coupling state.
    The coupling unit 3 also has a bush 36 with a protruding portion 360. The bush 36 is farther away from the central axis K than the power transmission means 38 when viewed radially from the central axis K of the clutch shaft 30. Between the bush 36 and the power transmission N2011 / 26300 30/09/2011 13:34 No .: R102 P. 015/036 25 13:31:55 30-09-2011 16/36 is arranged a bearing 361, so that the bushing 36 can rotate with respect to the power transmission means 38. The bush 36 is analogous to the power transmission means 38 along the central axis K of the crankshaft 30 axially displaceable. The bearing of the coupling shaft 30 takes place by means of two mutually beabstan-determinant bearing 37. The aforementioned bearings 37 are formed as radial bearings
    As can be seen from Figure 3, the clutch gear 39 is rotatably connected both to the coupling means 31, in particular the multi-plate clutch, as well as to the transmission clutch means 32. The gear coupling means 32 is formed coaxially with the coupling shaft 30 and partially protrudes into the cavity of the coupling shaft 32. Here, the gear coupling means 32 is formed such that the portion projecting into the cavity of the coupling shaft 30 is not rotationally connected to the coupling shaft 30, thus ensuring in that no rotational movement of the coupling shaft 30 is transmitted directly therefrom to the gear coupling means 32 when the coupling means 31 is inactive, ie solved or relaxed. The transmission coupling means 32 has a receiving portion 320 into which an input shaft 60 of the transmission 6 shown in FIG. 6 can penetrate. At the end remote from the gear coupling means 32 end of the coupling shaft 30, a vibration damper 21 is arranged.
    The clutch gear 39 meshes with an intermediate gear 4, which is arranged in the drive unit 1 between the electric machine 11 and the clutch unit 3. The intermediate gear 4 is mounted in the housing 10 of the drive unit 1 via bearings 40, in particular radial bearings
    The electric machine 11 is arranged outside of the preferably lubricating oil-filled housing 10 of the drive unit 1 and has an output shaft 110, which projects partially into the cavity of the housing 10. The projecting into the housing 10 portion of the output shaft 110 is connected to a gear 111, in particular formschligsig. The output shaft 110 and the gear 111 rotate about a center axis A of the output shaft 110. The complete electric machine 11 is supported by the housing 10 of the drive unit 1.

Since the storage the entire electric machine 11 via the radial bearings 113, the housing 10 is formed partially reinforced in the sections where the bearings 113 are arranged, for example, provided with stiffening ribs.
    The output shaft 110 and the coupling shaft 30 are arranged such that their central axes A, K are offset from one another. At this time, the center axis of the output shaft A is parallel to the center axis of the clutch shaft K.
    Furthermore, it is expedient to arrange the output shaft 110 of the electric machine 11 and the output shaft or the axis of rotation of the crankshaft of the internal combustion engine 2 parallel to each other and align in the same direction or with the same orientation, wherein the drive unit 1die the two mutually parallel engine by means of Kuppiungseinheit 3 with respect to the respective ready gestelite torque as needed coupled or decoupled. That is, the output side of the internal combustion engine 2 and the output side of the electric machine 11 are associated with a unitary side and a common housing wall of the drive unit 1, respectively. The drive unit 1 or its housing 10 thus preferably represents an end-face or distal end of this double or parallel unit, whereby, for example, a downstream transmission or an adjoining drive train can easily be connected to the drive unit 1 due to a relatively unrestricted installation space.
    The housing 10 has a first or front housing section 100 and a second or rear housing section 101, which are connected to one another via screws 102. These housing sections 100,101 essentially form half shells, which in the assembled state form the housing 10 of the drive unit 1. The rear housing section 101 is connected to upper screws 114 with a housing 112 of the electric machine 11.

The switching means 5 has a lever 50. The lever 50 is connected via a shaft 51 with a cam 52. Upon rotation of the hoist 50 forcibly rotates the shaft 51 and thus the cam 52. A rotation of the lever 50 can be effected by a schematically indicated in Figure 4 actuating means, in particular by an electrically driven or activatable actuator 550.
    Furthermore, the SchaEtmittel 5 a fork-shaped transmission means 53. The fork-shaped transmission means 53 has a shift fork 532 and a cam counterpart 533. The shift fork 532 has a substantially U-shape with a base and two legs extending from the base. The cam counter 533 is disposed on the shift fork 532 such that upon rotation of the lever 50, a force is applied to the cam counter 533 via the cam 52. In particular, the cam counterpart 533 is arranged on the basis of the shift fork 532. At the two legs of the Schaitgabei 532 a Drehiager 530 is arranged, over which the shift fork 532 can rotate. At the remote from the base ends of the two legs of the Schattgabel 532 a thrust bearing 531 is arranged in each case.
    It is expedient if the switching means 5 can be actuated either manually via muscle power or via the human body weight and also by means of an electrically operable actuator 550. In this case, the electric actuator 550 may be performed as a servomotor 551, in particular as an electric motor with a Spindeigetriebe whose spindle nut is motion-coupled to the switching means 5. Optionally, a manually releasable coupling connection 552, for example, a bolt connection 553 formed with splint lock, through which the switching means. 5 if necessary separated from the electric actuator 550, in particular manually and without tools can be decoupled.

    According to an advantageous development, the switching means 5 by means of a lever-shaped cable 554, by means of a linkage, by means of a hydraulic cylinder assembly of master and slave cylinder or by means of a similar power transmission means 555 with application of manual operating force switchable, whereby the coupling means 31 - Fig. 3 - by purely manual actuation force or by the weight of an operator in the decoupled state is überfohrbar Thus, the internal combustion engine 2 is secured in the decoupled drive state transferred. In order to enable a parallel, optional actuation of the manually to be adjusted power transmission means 555 and the electrically adjusted actuator 550, in particular a spin delmotors 551, the power transmission means 555 is tensile, but compressible or shortened executed. In particular, can be provided as power transmission means 555 between the actuator 550 and the lever 50 of the switching means 5, a cable or chain connection, or other tensile forces transmitting, but against compression or shear forces decoupling force transmission means 550. Such a power transmission means 550 can also be formed by a telescopic tension member 556, which transmits tensile forces and absorbs shear forces or not transmits by telescopic shortening its length from its first end to its distal end, as schematically indicated in Fig. 4 has been.
    FIG. 5 shows the switching means 5 in a state installed in the drive unit 1. As can be seen from Figure 5, a fixing of the sound means 5 in at least one cylindrical fixing section 13 of the housing 10 of the drive unit 1 via bolts 55. More precisely, the bolts 55 are inserted into the respective cylindrical fixing portion 13 and come into contact with the pivot bearing 530 of the shift fork 532. A spring 54 is coupled to the shift fork 532 such that it is assured that after a return movement of the lever 50 to its undeflected position, the shift fork 532 is also rotated to the undeflected position.

    Receiving portion 320 of the gear coupling means 32 and is connected to the Getriebekupplungsmittei 32 drehest. The connection can be made in a positive way.
    The mode of operation of the drive unit according to the invention is explained below. Although the explanation is made with reference to the reference numerals, the operation is not limited to the embodiment shown in the figures.
    The drive unit 1 can be operated in three different states. In a first operating state, both the torque of the internal combustion engine 2 and the torque of the electric machine 11 are transmitted to the input shaft 60 of the transmission 6 or to a drive train of a vehicle. In a second operating state, only the torque of the internal combustion engine 2 and in a third operating state, only the torque of the electric machine 11 is transmitted to the input shaft 60 of the transmission 6.
    In an operation of the drive unit 1 in the first operating state, the torque of the output shaft of the internal combustion engine 2 is transmitted to the coupling shaft 30 of the Kupplungseinhett 3 and thus the Kupplungsmittei 31. Since the spring pack 33 is in the prestressed state and thus the flange 381 of the power transmission means 38 exerts a force on the Kuppjungsmittel 31, this is in a coupled or coupling state. Thus, the torque of the Kupplungsweiie 30 is transmitted via the Kupplungsmittei 31 to the clutch gear 39. Since the gear coupling means 32 is connected to the clutch gear 39 rotatably, the torque of the clutch shaft 30 is finally transmitted to the gear coupling means 32 and to the input shaft 60 of the transmission 6 connected to the gear coupling means 32. The torque of the electric machine 11 is transmitted to the intermediate gear 4 via the output shaft 110 or the gear 111 connected to the output shaft 110. Since the intermediate gear 4 with the clutch tooth N2011 / 26300 30/09/2011 13:37

    In the second operating state, a torque transmission from the output shaft of the internal combustion engine 2 to the input shaft 60 of the transmission 6 is analogous to the first operating state described above. The only difference between the two operating states is that in the second operating state of the electric machine 11 no torque is provided. In this state, no electrical energy is consumed or absorbed by the electric machine 11. The torque applied by the internal combustion engine 2 to the clutch gear 39 is transmitted, in addition to the gear coupling means 32, to the intermediate gear 4 and thus to the gear 111 of the output gear 110 of the electric machine 11. This ensures that the output shaft 110 of the electric machine 11 rotates upon rotation of the output shaft of the internal combustion engine 2. The rotation of the output shaft 110 of the electric machine 11 can be used as a flywheel for the internal combustion engine 2.
    In the third operating state takes place, as already mentioned above, only a threat torque transmission of the torque of the electric machine 11 to the transmission coupling means 32 and thus to the input path 60 of the transmission 6. By an actuation of the switching means 5, the coupling means, in particular the multi-plate clutch, converted into an uncoupled or decoupled state, so that no torque transmission from the clutch world 30 to the clutch gear 39 is more. The torque transmission from the output gear 110 of the electric machine 11 to the gear coupling means 32 takes place in the manner described for the first operating state.
    A decoupling of the coupling shaft 30 of the clutch gear 39 by means of the switching means 5 can be done as follows. The actuation of the Schaltmittefs 5 via actuating means can be done manually or electrically. Upon actuation, the lever 50 of the switching means 5 is rotated as a result of the rotation of the lever 30/09/2011 13:38

In this case, the fork-shaped transmission means 53 rotates about the pivot bearing 533. Upon rotation of the transmission means 53, the thrust bearings 531 press on the protruding portion 360 of the sleeve 36 against the spring force of the spring assembly 33th Since the force exerted by the transmission means is greater than the spring force of the spring Federpaketes 33, the power transmission means 38 moves axially in a direction away from the coupling means 31. That is, the flange 381 of the power transmission means 38 no longer presses against the coupling means 31. Thus, in a design of the coupling means 38 is achieved as a multi-plate clutch, that the blades are no longer pressed against each other, and thus can no longer transmit the torque of the Kupplungswetle 30 to the clutch gear 39. Thus, the multi-plate clutch is in an uncoupled or decoupled state.
    When moving the switching means 5 to its initial position, no force is exerted on the cam counterpart 533 by the cam 52. A rotation of the fork-shaped transmission means 53 in its initial position is ensured by the spring 54. As a result of the reverse rotation of the transmission means 53 in the starting position of the pressure bearings 531 no Kraltauf the protruding portion 360 of the sleeve 36 is exercised. By the spring assembly 33, a force is exerted on the projection 380 of the power transmission means 38, which causes the power transmission means 38 and thus also the sleeve 36 to move in the direction of the coupling means 31. A movement of the bushing 36 is achieved in that it is frictionally connected via the bearing 37 with the power transmission means 38. In this case, the power transmission means 38 moves as long as towards the coupling means 31 until a sufficiently high force is transmitted to the coupling means 31 through the flange 381, which ensures that the coupling means 31 is in a coupled, the respective torque transmitting state N2011 / 26300 P.022 / 036 30/09/2011 13:39 No .: R102 25 13:36:56 30-09-2011 23/36
