FIG. 8 a diagrammatic illustration of a half longitudinal section through a clutch device according to a seventh embodiment. -
FIG. 1 shows a half longitudinal section through anillustrative clutch device 100. Afirst input side 110, asecond input side 115, afirst output side 120 and asecond output side 125 are arranged around arotation axis 105. - A
first clutch 130 lies between thefirst input side 110 and thefirst output side 120, asecond clutch 135 lies between thefirst input side 110 and thesecond output side 125, and athird clutch 140 lies between thefirst input side 110 and thesecond input side 115. The first twoclutches third clutch 140 may be offset axially relative to one of the twoother clutches - The
first input side 110 is configured for connection to anelectrical machine 145, which is designed as a first drive motor and comprises arotor 150 and astator 155. Theelectrical machine 145 may be an internal rotor type, wherein thestator 155 lies radially outside therotor 150. Thestator 155 may include at least one magnetic coil, and therotor 150 comprises at least one permanent magnet. Therotor 150 may lie radially outside theclutches first input side 110 in a fixed manner by means of riveting. Thesecond input side 115 may be configured for connection to a combustion machine, in particular an internal combustion engine, further may be a reciprocating piston engine, which is designed as a second drive motor. - The output sides 120 and 125 are configured for connection to input shafts of a double gearbox (not shown). The double gearbox normally couples each of the input shafts via a separate gearwheel pair to a common output shaft, which in turn acts on a drive wheel of the motor vehicle. In order to select a gear, either the first clutch 130 or the
second clutch 135 is closed while the respective other clutch 125, 130 remains open. On each gearbox shaft, the double gearbox may include several gearwheel pairs, only one of which is engaged at a time. A gearwheel pair may usually be engaged or disengaged when it is connected to anoutput shaft clutch - In particular, the
clutch device 100 is configured to be used in a drive train of the motor vehicle. Here, the motor vehicle may preferably be operated in a hybrid mode, i.e. driven alternatively by the internal combustion engine, by theelectrical machine 145 or by both drive motors. If the internal combustion engine is used, thethird clutch 140 is closed. If theelectrical machine 145 is used, it is normally actuated electrically such that torque is transferred. The two drive motors may apply both positive and negative torque to the drive train. Theelectrical machine 145 may also receive kinetic energy from the drive train and convert this into electrical energy, which for example may be temporarily stored in an energy accumulator. Because of its compact structure, theclutch device 100 is particularly suitable for installation transversely at the front of the motor vehicle. - A
first actuator device 160 is assigned to thefirst clutch 130, asecond actuator device 165 to thesecond clutch 135, and athird actuator device 170 to thethird clutch 140. All threeactuator devices clutches clutches actuator device hydraulic actuator devices - The three
clutches common housing 175 which is at least partially filled with aliquid medium 180, in particular an oil. The medium 180 may also be used as a working medium of thehydraulic actuator devices clutches first clutch 130 and thesecond clutch 135 are of the multiplate type, in order to allow finely-controlled opening and closing of the torque flow through theclutches - In the embodiment shown, a
radial flange 185 is arranged axially between thefirst clutch 130 and thesecond clutch 135 as a thrust bearing, against which theclutches actuator device actuator devices clutch device 100, so that no resulting forces need be supported externally. -
FIG. 2 shows a diagrammatic illustration of a half longitudinal section through theclutch device 100 shown inFIG. 1 . - The
first clutch 130 has afirst friction packet 200. Thesecond clutch 135 has asecond friction packet 205, and thethird clutch 140 has athird friction packet 210. Thefirst friction packet 200 comprises afirst friction partner 215 and asecond friction partner 220. Thesecond friction packet 205 comprises athird friction partner 225 and afourth friction partner 230. Thethird friction packet 210 comprises afifth friction partner 235 and asixth friction partner 240. In the embodiment, by way of example, the first, third and/orfifth friction partners fifth friction partners sixth friction partners sixth friction partners - The first and second friction partners 215, 220 of the
first friction packet 200 are arranged alternately in the form of a stack to form thefirst friction packet 200. The third and fourth friction partners 225, 230 are arranged alternately adjoining one another in a stack. In thethird friction packet 210, the fifth andsixth friction partners third friction packet 210 has a smaller number of fifth and/orsixth friction partners first friction packet 200 and/or thesecond friction packet 205 has a number of first and second friction partners 215, 220 and/or third and fourth friction partners 225, 230. This is necessitated by the fact that, for example, theelectrical machine 145 transmits a lower torque, which has to be transmitted by the third clutch 140 between thefirst input side 110 and thesecond input side 115, than is provided by the second drive motor on thesecond input side 115. - A more detailed explanation of the arrangement of the
clutches respective friction packet - In
FIG. 2 , thefirst clutch 130 is arranged offset axially relative to thesecond clutch 135. In this case, thefirst clutch 130 and thesecond clutch 135 are arranged in radial overlap. Here, a radial overlap is understood to exist when thefirst clutch 130 and/or thesecond clutch 135 and possibly the third clutch 140 are projected into a plane arranged perpendicularly to therotation axis 105 and theclutches second clutch - In the embodiment, the
first clutch 130 may have the same radial extent as thesecond clutch 135. Of course, it is also possible for the first clutch 130 to be of radially wider or narrower design than thesecond clutch 135. In this case, it is advantageous if thefirst clutch 130 is arranged so as to radially overlap thesecond clutch 135 at least partially and preferably completely. - The third clutch 140 may be arranged axially between the
first input side 110 and thefirst clutch 130, on a side of the first clutch 130 facing away from thesecond clutch 135. Thefirst clutch 130 is arranged axially adjacent to thesecond clutch 135. This configuration has the advantage that the radial installation space is particularly small. In this case, the third clutch 140 fully overlaps thefirst clutch 130 and thesecond clutch 135. Thus, thethird clutch 140 is arranged in the radial installation space of the first andsecond clutches third clutch 140 is arranged offset axially relative to thesecond clutch 135 and to thefirst clutch 130. The third clutch 140 may be designed to be of the same radial width as thefirst clutch 130 and thesecond clutch 135. It is also possible for the third clutch 140 to be of radially thinner or wider design than thefirst clutch 130 and/or thesecond clutch 135. - In
FIG. 2 , a variant of the arrangement of theclutches FIGS. 1 and 2 is indicated in dashed lines. In this case, thethird clutch 140 is arranged axially adjacent to thesecond clutch 135, on a side facing away from thefirst clutch 130. Here, it is likewise possible for thefirst input side 110 to be arranged on a side of thesecond clutch 135 facing away from thefirst clutch 130. Thefirst clutch 130 is arranged axially adjacent to thefirst input side 110. Thefirst input side 110 can be connected in a torque-transmitting manner to thethird clutch 140 by means of elements that are not shown. -

Thefirst input side 110 may be arranged radially on the outside relative to thethird clutch 140. As illustrated by solid lines inFIG. 3 , the third clutch 140 may be arranged in axial overlap with thefirst clutch 130. Here, an axial overlap means that at least two of theclutches rotation axis 105 is arranged and theclutches third clutch second clutches - In a variant (illustrated in dashed lines), the
third clutch 140 is arranged radially on the outside relative to thesecond clutch 135. Thethird clutch 140 is arranged in axial overlap with thesecond clutch 135. The decision as to whether thethird clutch 140 is arranged radially on the outside in axial overlap with the first clutch 130 or in axial overlap with thesecond clutch 135 depends on a potential installation space requirement, and therefore the arrangement described inFIG. 3 allows more flexible adaptation of the third clutch 140 to the available installation space limits. -

FIG. 7 shows a diagrammatic illustration of a half longitudinal section through aclutch device 100 according to a sixth embodiment. Theclutch device 100 is of similar design to theclutch device 100 shown inFIGS. 5 and 6 . Here, thefirst clutch 130 is arranged radially on the inside relative to thesecond clutch 135. Here, thefirst clutch 130 and thesecond clutch 135 are arranged in axial overlap and may be preferably in full axial overlap. Here, by way of example, thefirst clutch 130 is coupled radially on the inside to thefirst output side 120. By way of example, thesecond clutch 135 is coupled radially on the inside to thesecond output side 125. Thefirst clutch 130 is coupled radially on the outside to thefirst input side 110. Thesecond clutch 135 is likewise coupled radially on the outside to thefirst input side 110. - The
third clutch 140 is arranged offset radially relative to thefirst clutch 130 and thesecond clutch 135. Thethird clutch 140 is furthermore arranged in axial overlap with thefirst clutch 130 and thesecond clutch 135. By way of example, thethird clutch 140 is here coupled radially on the inside to thesecond input side 115 and radially on the outside to thefirst input side 110. Of course, it is also conceivable for the third clutch 140 to be coupled radially on the outside to thesecond input side 115 and radially on the inside to thefirst input side 110. - In a variant of the embodiment of the
clutch device 100 shown inFIG. 7 , thethird clutch 140 is arranged on the opposite side inFIG. 7 . In this case, thethird clutch 140 is likewise arranged in axial overlap with thefirst clutch 130 and thesecond clutch 135. -
FIG. 8 shows a diagrammatic illustration of a half longitudinal section through aclutch device 100 according to a seventh embodiment. Theclutch device 100 is of substantially identical design to theclutch device 100 shown inFIG. 7 . As a departure therefrom, thesecond clutch 135 is arranged radially on the inside relative to thefirst clutch 130. Thus, thesecond output side 125 is also arranged radially on the inside relative to thefirst clutch 130 and to thesecond clutch 135. Thethird clutch 140 is likewise arranged in axial overlap with the first andsecond clutches - Attention is drawn to the fact that it is also conceivable, in addition to the embodiments of the
clutch device 100 which are shown inFIGS. 1 to 8 , for theclutches - Attention is also drawn to the fact that the features of the
