Definitions
- Multifac coupling device with two coupling arrangements that can be coupled for common rotation
- the invention relates to a multiple clutch device, possibly double clutch device, for the arrangement in a drive train of a motor vehicle between a drive unit and a transmission, the clutch device having a first clutch arrangement assigned to a first transmission input shaft and a second clutch arrangement assigned to a second transmission input shaft, wherein Of the two transmission input shafts that define an axis of rotation of the clutch device, one extends through the other, the clutch arrangements each having an input side that can be directly or indirectly coupled or coupled to an output shaft of the drive unit via a common input side of the clutch device, and wherein the first clutch arrangement has a first output side which is coupled or can be coupled to the first transmission input shaft for common rotation and the second clutch arrangement has a second output has side, which is coupled or can be coupled to the second transmission input shaft for common rotation.
- Such a multiple clutch device is known for example from DE 100 04 179 A1.
- the two clutch arrangements are designed as wet-running multi-plate clutch arrangements, which can be actuated via a respective hydraulic slave cylinder integrated in the clutch device.
- the arrangement of the clutch arrangement is such that a disk set of one clutch assembly is the disk set of the other clutch arrangement surrounds radially outside.
- the inner disk carriers of the two clutch arrangements which each serve as the output side, each have a coupling hub, which sits on the respectively assigned transmission input shaft and is connected to it in a rotationally fixed manner via driving information.
- One of the two clutch arrangements serves as a starting clutch, namely the one that is assigned to the transmission input shaft, via which the torque flow runs when the starting gear is engaged (usually first gear). Since the clutch arrangement is subjected to high stresses due to friction when starting, it is expedient to assign the clutch arrangement comprising the radially outer disk set to the starting gear or the transmission input shaft in question, since its disks have a larger inner diameter and a larger outer diameter than the disks of the other clutch arrangement and accordingly in comparable radial lamella length (outer diameter - inner diameter) offer a larger friction surface and are accordingly more susceptible to friction.
- the radial dimension of the double clutch essentially depends on the friction surfaces of the disks, so that ultimately the frictional stress (friction energy) that occurs during start-up or other slip operation indirectly limits the achievable compactness (radial dimension and axial dimension) of the double clutch.
- the first and the second output side can be coupled to one another directly or indirectly for common rotation.
- the proposal of the invention it is possible to couple the two output sides of the clutch arrangements directly or indirectly for common rotation, so that the drive torque from the drive unit in parallel via both clutch arrangements to the currently "active" transmission input shaft, on which a transmission gear (possibly starting gear) is engaged is, can be transferred.

- the two transmission input shafts can be coupled, for example, by a corresponding coupling device in the transmission.
- the second output side can be coupled to the first transmission input shaft for common rotation and / or that the first output side can be coupled to the second transmission input shaft common rotation can be coupled.
- the coupling of the second output side to the first transmission input shaft can be produced and canceled by axially shifting a coupling hub on the output side mounted on at least one of the transmission input shafts, and / or that the coupling of the first output side to the second transmission input shaft by axially shifting one to at least one of the transmission input shafts mounted coupling hub on the output side can be produced and canceled.
- the coupling hub in question has driving information assigned to the first transmission input shaft and driving information assigned to the second transmission input shaft, and that the transmission input shafts have corresponding counter-driving information.

- the coupling of the first and second coupling hubs to one another can be produced and canceled by axially displacing the coupling hubs relative to one another.
- the first or the second coupling hub can be mounted axially displaceably on at least one of the transmission input shafts.
- the two coupling hubs can advantageously have mutually associated driver formations via which the coupling hubs can be coupled to one another.
- the coupling hub in question has at least one hydraulic slave cylinder is assigned, via which the coupling hub, possibly with the assistance of a return spring arrangement, can be displaced between a first and a second axial position, the coupling being established in one axial position and the coupling being released in the other axial position.
- the hydraulic slave cylinder can be connected or connectable to an assigned hydraulic pressure source via an annular channel between the first and the second transmission input shaft.

- DE 100 04 179 A1 which also provides the person skilled in the art with additional background information which makes it easier to understand the construction according to FIG. 1.
- the double clutch 10 can, for example, be assembled from individual parts as follows and installed in a motor vehicle drive train.
- the outer disk carrier 28 of the radially outer clutch arrangement is connected to the input hub 40, which can also be referred to as the central hub, e.g. B. by welding.
- the piston 60 for the radially outer clutch arrangement is then inserted together with its return springs 90 and the associated seals.
- the outer disk carrier 32 is the radially inner clutch connected to the input hub 40, for example welded.
- the piston 62 of the radially inner clutch arrangement together with the associated return springs 92 and the associated seals are then inserted.

- the radial bearing 150 can now be used.
- the inner disk carrier 34 of the radially inner clutch arrangement together with the axial bearing 156 can be inserted.
- the outer and inner disks of the radially inner clutch arrangement, that is to say the disk pack 26, can then then be inserted and secured by the securing or holding ring 162.
- the inner disk carrier 30 of the radially outer clutch arrangement together with the axial bearing 154 is then expediently inserted.
- the outer and inner plates of the radially outer clutch arrangement that is to say the plate set 22, can then then be inserted and secured by the securing or retaining ring 160.
- the double clutch 10 according to FIG. 1 can be mounted as a finished module in the transmission housing bell 14.
- the transmission is preferably brought into a position in which the transmission housing bell 14 is open at the top, so that the double clutch 10 can be axially lowered from above into the receiving space 12 and thereby lowered onto the rotary shaft arrangement 16, 18, 80.
- a securing ring 170 is attached to the inner disk carrier 30, for example fixed to the inner disk carrier by caulking.
- the radial bearing and sealing arrangement (radial bearing 150, radial shaft sealing ring 120, 122) acting between the rotary shafts 16, 18 and 80 and the input hub 40 are preferably preassembled on the double clutch construction 10 and fixed in a suitable manner, so that the double clutch takes up little time can be installed on the transmission side and the risk of incorrect assembly or incomplete assembly is reduced.
- the cover 130 After the double clutch has been pushed onto the rotary shafts 16, 18, 80, the cover 130 must then be installed and secured by the components 134, 136.
- the bearings 152 and 158 can be appropriately preassembled on the module.
- the main difference between the double clutch of FIG. 2 and the double clutch of FIG. 1 is that the coupling hub 52 of the inner disk carrier 30 is axially displaceably mounted on both transmission input shafts 16 and 18 and two groups of entrainment formations, possibly toothings, 202 and 204, to which corresponding counter-driving formations 206 and 208, possibly toothings, of the transmission input shafts 16 and 18 are assigned.
- the entrainment formations 208 of the radially inner transmission input shaft 18 are axially longer compared to the entrainment formations of the transmission input shaft 18 according to FIG. 1, which are only used there for the rotationally fixed coupling of the coupling hub 54 of the inner disk carrier 34, and the entrainment formations follow in the direction of FIG.
- the coupling hub 52 is only in rotary driving engagement with the radially outer transmission input shaft 16, specifically via the driving information 202, 206.
- the coupling hub 52 can counteract the action of a return spring arrangement 212 formed by a plate spring are supported on the one hand on the coupling hub 52 and on the other hand via a support ring 214 and an axial bearing 154 'on the inner disk carrier 34, so that the driving information 204 of the hub 52 comes into engagement with the driving information 208 of the transmission input shaft 18 and thus the inner disk carrier 30 the radially inner transmission input shaft 18 for common rotation and thus to couple the two inner disk carriers 30 and 34 for common rotation.
- the rotational driving engagement between the toothings 202 and 206 can be maintained, as shown in FIG. 3, or these toothings can disengage, so that the transmission input shaft 16 from the double clutch with respect to the rotation of the inner disk carrier 30 is uncoupled.
- Fig. 3 shows the state of the double clutch 10 mentioned, in which the two inner plate carriers, that is, the output sides of the two plate clutch arrangements, are coupled for common rotation by means of the transmission input shaft 18.
- the radially outer transmission input shaft 16 is still in rotary engagement with the coupling hub 16, so that during operation it must be ensured that no gear is engaged on the transmission input shaft 16.
- the transmission input shaft 16 can then rotate loosely with the transmission input shaft 18.
- the coupling hub 52 can be actuated hydraulically in the sense of an axial displacement against the restoring force of the restoring spring 212.
- a hydraulic ring channel 220 is formed between the transmission input shafts 16 and 18, via which a hydraulic slave cylinder formed by the two transmission input shafts 16 and 18 and the hub 52 can be acted upon by hydraulic pressure, the hub 52 serving as a piston of the slave cylinder.
- the hydraulic Slave cylinder or hydraulic line 220 is sealed by sealing rings 222 or 224 or the like, which act between the respective transmission input shaft and an associated inner circumferential section of hub 52. If the switching pressure acting on the hydraulic slave cylinder is removed, the plate spring 212 pushes the hub 52 from the position shown in FIG. 3 back to the position shown in FIG.
- the ability to connect the two output sides of the two clutch arrangements enables, for example, the start-up load to be absorbed by both clutch arrangements, but that the overall drive torque transmitted by both clutch arrangements is only transmitted to the transmission and thus to the driven wheels via a transmission input shaft.
- An advantage of such an arrangement is that the effective drag torque is lower at low temperatures and that splashing and sticking is avoided or can be avoided more easily, in particular in that the coupling arrangement with the smaller lamella outer diameter does not or only slightly into the one in the coupling housing (Gearbox housing bell) remaining cooling oil is immersed.
- the radially outer clutch arrangement When starting off in a state according to FIG. 2 with the radially inner clutch arrangement, the radially outer clutch arrangement runs at a certain differential speed as a result of drag torques, provided that no gear is engaged on the transmission input shaft 16.
- this clutch arrangement can be synchronized with the speed of the inner clutch arrangement.
- the output or output side of the radially outer clutch arrangement can be coupled to the output or output side of the radially inner clutch arrangement by corresponding actuation of the coupling hub 52.
- the radially outer clutch arrangement can be switched on completely, and it can then be used with both clutch arrangements, for example in first gear be approached.
- the output side of the two clutch arrangements could first be coupled to one another by corresponding actuation of the coupling hub 52 and only then switched on (engaged) by appropriate actuation of their hydraulic slave cylinder, whereupon both clutch arrangements are then started, for example, in first gear can.
- the radially outer clutch arrangement 20 is opened first, so that a gear, for example the second gear, can then be engaged on the radially outer transmission input shaft 16.
- the load can then be transferred from the starting gear to the second gear in a manner known per se by means of the known overlapping circuit of the two clutch arrangements, so that an interruption in tractive force is avoided.
- FIG. 2 The construction of FIG. 2 and the assignment of the first gear to the radially inner clutch arrangement 24 and the second gear to the radially outer one
- Coupling arrangement 20 also offers the advantage that starting in the second
- Gear with a much higher partial load is possible than if the second gear were assigned to the radially inner clutch arrangement. If the second gear were assigned to the radially inner clutch arrangement, it would be possible, for example, to start with only 20 to 30% of the maximum load. By assigning the second gear to the radially outer clutch arrangement, a partial load of 60 to 70% can be started in the second gear, for example. A further increase is possible by the fact that the two also start off in second gear
- FIGS. 4 and 5 essentially corresponds to the exemplary embodiment of FIGS. 2 and 3.
- the two output sides of the clutch arrangements according to FIGS. 4 and 5 are not arranged to rotate together by means of the radially inner transmission input shaft 18 are coupled, but that the coupling hubs 52 and 54 are associated driving formations, possibly toothings, 230 and 232, which do not mesh with one another according to FIG. 4 and mesh with one another according to FIG. 5 as a result of an axial displacement of the coupling hub 52 in the direction of the drive unit and thus couple the two coupling hubs 52 and 54 to one another for common rotation.
- An advantage of the construction according to FIGS. 4 and 5 is that the entraining formation 208 of the radially inner transmission input shaft 18 can be made axially shorter, which enables the double clutch 10 to be made more compact axially.
