The 1 to 4 each show a part of a drive train of a motor vehicle with drive (in this case an internal combustion engine), clutch (in this case a dual clutch) and transmission (in the present case a dual-clutch transmission with two partial transmissions) in half cut. In the present case is the double clutch with a crankshaft 4 the internal combustion engine (or other comparable drive shaft in a drive other than an internal combustion engine) and connected to the two transmission input shafts of a dual-clutch transmission. In the present case, the transmission input shafts are arranged so as to be nested in order to save space, the present disclosure not being restricted to this arrangement. Rather, the proposed storage concept can also be used in completely different arrangements of the transmission input shafts.

Between drive unit and double clutch 1 is according to the in the 1 to 4 embodiments shown no torsional vibration damping connected. Rather, the double clutch is directly with the crankshaft 4 over the screw connection 7 (with one or more screws distributed around the circumference) and the flexplate 8th connected. The crankshaft 4 can be used to center the flexplate 8th a paragraph 4a exhibit. Between flexplate 8th and screw connection 7 at least one washer is arranged. This at least one washer may act as a separate washer under each of the screws (usually: 3) of the threaded connection 7 or be formed as a concentric ring or as a plurality of segments.

The flexplate 8th is with a driver plate 9 via a riveted joint 10 associated with one or more circumferentially distributed rivets. The present is about the riveted joint 10 also a starter ring gear 11 with the driver plate 9 (also referred to as driver cup) connected.

The driver plate 9 is with an intermediate printing plate 12 (also referred to as the central plate) via a screw connection 13 (with one or more circumferentially distributed screws) connected. This screw connection 13 is presently arranged radially, but can also be arranged axially or at a different angle to the normal on the transmission input shaft axes. Likewise, a snap connection is conceivable at this point. In addition, the connection can be made directly or indirectly.

Due to the screw connection 13 and / or snap connection, the intermediate pressure plate 12 and the driver plate 9 - Including the components associated with these components - separated and reconnected. Accordingly, the screw connection 13 and / or snap connection with the intermediate pressure plate 12 a dividing line between two coupling halves, wherein a first hitch be half has the connection and mounting components of the coupling and wherein a second coupling half comprises the actual coupling components. The mounting method explained below relies substantially on such a separation into two coupling halves in order to mount the double clutch mounted on the engine side via a fixed bearing.

Between the intermediate pressure plate 12 and a motor-side pressure plate 14 the engine-side partial clutch are friction linings of a first clutch disc 5 (with integrated damper) can be clamped. The first clutch disc 5 is rotationally fixed about a hub part with a first transmission input shaft 14 connected, which is designed here as a solid shaft.

The first transmission input shaft 14 is in a second transmission input shaft 15 , which is designed as a hollow shaft, rotatably arranged. A hub part of a second clutch disc 6 is rotationally fixed to the drive end of the second transmission input shaft 15 connected. At the second clutch disc 6 (with damper) friction linings are fixed radially on the outside, between the intermediate pressure plate 12 and a transmission-side pressure plate 16 the gearbox side coupling can be clamped.

The motor-side pressure plate 14 is with a tie rod 17 connected. The tie rod 17 rests on a plate spring 18 from. The plate spring 18 is about a wear adjustment to a clutch cover 19 the transmission-side part clutch supported. The clutch cover 19 is with the intermediate pressure plate 12 connected. On the clutch cover 19 is another plate spring 20 supported.

Both disc springs 18 . 20 have radially inner plate spring tongues, which with actuating bearings 21 . 22 in operative connection by a first actuating bearing 21 on the first lever spring 18 the drive-side part clutch and a second actuator bearing 22 on the lever spring 20 the transmission side part coupling can act. Actuating bearing and associated plate spring as an actuating lever accordingly form an actuating device for the respective sub-coupling, wherein the respective actuating lever, the respective pressure plate 14 . 16 in the axial direction relative to the intermediate pressure plate 12 can shift limited.

Instead of Disc springs can also lever springs as an operating lever be used.

The actuation bearings of the actuators are via hydraulic devices 23 . 24 acted upon by an actuating force. This hydraulic central release with hydraulic devices 23 . 24 rests on a coupling housing 3 from.

Instead of a hydraulic actuator can also mechanical lever systems with electric or hydraulic Actuators are used.

The driver plate 9 (the driver pot 9 ) is, as already stated, on the flexplate 8th with the crankshaft 4 over the screw connection 7 connected. The driver pot 9 includes an axial cylindrical portion 9A (where the screw 13 or attack snap connection), a radial portion 9B and a radially inwardly disposed axial neck portion 9C , The radially inwardly disposed axial neck portion 9C is with a bearing outer ring of a rolling bearing 25 connected.

The bearing inner ring of the rolling bearing 25 is with a support element 26 connected, wherein the carrier element 26 on the drive housing 2 is attached. The rolling bearing 25 is presently the drive side arranged fixed bearing, ie the rolling bearing 25 (Fixed bearing) is fixed in the axial direction, and / or can accommodate tilting moments in the axial direction and has a degree of freedom in the radial direction.

Below is the connection to the interface 28 between drive (engine block) and transmission (gear block) explained in more detail by the supported on the engine block carrier element.

The drive-side (motor-side) clutch bearing 25 (= Fixed bearing) is according to the embodiment according to 1 radially outside the crankshaft flange 4 arranged and over the driver plate 9 (Mitnehmertopf 9 ) with the double clutch 1 connected by the bearing outer ring with the radially inner axial neck portion 9C and a bearing cap 27 axially fixed, bearing cap 27 and axial neck section 9C are connected to each other via rivet connections.

On the engine block and / or on the clutch bell, the engine-side fixed bearing 25 in the axial direction and against tilting of a support element 26 supported, with the engine block 2 and / or the transmission block (clutch bell) is connected.

According to the in 1 embodiment shown is the connection between rolling bearings 25 and carrier element 26 radially displaceable. By this radial degree of freedom, the rolling bearing 25 on the crankshaft 4 Set the default rotation axis. This can be achieved constructively, for example, by means of a large radial clearance fit between the carrier element 26 and the support member facing this bearing inner ring of the bearing 25 respectively.

In In the axial direction, the bearing inner ring, on the other hand, has to be grasped with little play be as little as possible Axial or Allow tilting movements.

For example, to prevent rattling or Mitwandern, the bearing inner ring can also be biased radially and / or axially with spring elements. In 1 is an example of a spring element 128 shown that the bearing inner ring of the bearing 25 preloaded in the axial direction.

Around to facilitate sliding of the bearing inner ring in the radial direction and about the wear too reduce, can also sliding bearing elements or special surface treatments or coatings will be used.

The embodiment of the double clutch 1 to 1 Accordingly, based on a bearing concept in which a roller bearing as a motor side bearing (ie between engine and actual clutch) is arranged and axial forces and tilting moments of the clutch receives and wherein a radial degree of freedom between the bearing and the engine block or the gear block is provided so that the bearing on the axis of rotation of the crankshaft 4 can adjust, whereby a radial relative movement can be avoided.

In order to avoid or at least minimize the radial relative movement per motor revolution, the smallest possible coaxial error between the fixed bearing (rolling bearing 25 ) and the crankshaft seat (driver cup 9 and flexplate 8th ) to be available. If this is not feasible, the fixed bearing (bearings 25 ) are also each provided with a radial degree of freedom on the fixed bearing coupling side (ie seen from the fixed bearing in the direction of the clutch) and on the fixed bearing housing side (ie seen from the fixed bearing in the direction of the engine), as shown in 4 is shown.

With one degree of freedom on the clutch side and on the housing side of the fixed bearing, the bearing can move freely within certain limits until the radial Gleitbewegun conditions on both sides of the fixed bearing are minimal, so that an energy minimum is reached. This energy minimum is reached when the fixed bearing on the axis of rotation of the crankshaft 4 has set. In order to facilitate and maintain this setting of an energy minimum, spring elements can be used, in particular in the case with one radial degree of freedom on the coupling side and on the housing side of the fixed bearing, which bias the bearing rings axially or radially. Also sliding elements, surface treatments and surface coatings can positively influence such an adjustment of the energy minimum.

For heavy fixed bearings (rolling bearings 25 ) can on the non-rotating connection side of the fixed bearing (ie the fixed bearing housing side, ie the fixed bearing inner ring in the embodiment of the 1 . 2 and 4 or the bearing outer ring in the embodiment according to 3 ) also be attached a device that balances the weight and inertial forces of the fixed bearing, z. B. a counterweight or a radially acting spring.

As stated in the introduction, the torque of the engine (the drive) from the crankshaft 4 over the flexplate 8th transferred to the double clutch. Axial and wobble movements of the crankshaft flange as well as axial tolerances of the flexplate become thereby 8th balanced. alternative to A Flexplate can also be another type of elastic connection, such. B. leaf springs, are used. In addition, it is also possible to use a kind of damper whose tangentially arranged helical or bow springs serve less the damping of torsional vibrations, but the axial and tumbling motion of the crankshaft 4 compensate.

For installation of the motor-side fixed bearing 25 mounted double clutch 1 It is particularly useful if a separation point between the actual clutch and the connection and storage components is provided on the engine. The attachment and storage components comprise in particular the carrier element 26 , the camp 25 and the driver pot 9 , The actual coupling elements comprise in particular the central plate 25 , the printing plates 14 . 16 , the tie rod 17 , the clutch cover 19 and the lever springs. As a rule, the controls ( 21 - 24 ) mounted separately in the clutch bell (the actuators but also with the actual coupling elements can be installed together).

In 1 this separation point is a radial screw connection 13 between the central plate 12 and the driver pot 9 (the connecting element between motor-side fixed bearing 25 and central plate 12 ) realized. As a result, the connection and storage components can be separated from the coupling components and to the engine 2 (pre) be mounted. The mounting on the engine or on the motor housing 2 takes place in such a way that the flexplate 8th on the crankshaft 4 bolted and the support element 26 on the engine block 2 is attached. This can, for example, as in 1 shown at the engine block transmission block interface 28 respectively.

In addition, the carrier element can 26 possibly radially inward at the point 29 on the engine block 2 support.

The actual double clutch 1 is without the connection and storage components in the clutch bell 3 positioned. Since the actual coupling components in this assembly phase, when the engine and transmission are not yet connected to each other, is separated from the connection and storage components, the actual coupling components require a provisional fixation. This can be done, for example, by radial screws 30 done by the clutch bell 3 starting with the dual-clutch components. A provisional fixation can also be realized by an automated mounting device. Also, plastic elements may be provided which serve as a temporary fixation and tear off automatically at the first start of the drive train.

If the motor with the connection and bearing components and the gearbox are provided with the actual clutch components, the engine and gearbox can be bolted together. This in 1 shown carrier element 26 lies between the engine and transmission and thus becomes in the place 28 fixed. Subsequently, the connection and storage components are reconnected to the actual coupling components. For this purpose, z. B. openings in the clutch bell 3 be provided so that the separation point 13 is accessible. In addition to the in 1 shown radial screw connection, the separation point 13 also be designed as an axial screw or as a snap connection. For most applications, this is expedient if the separation point is arranged as close as possible to the motor rear wall. After the separation point is connected, the provisional fixation 30 the double clutch removed or disabled.

As stated, the carrier element is 26 at the separation point 28 between engine block 2 and gear bell 3 tethered. In order to perform the carrier elements as possible compact and streak, but its attachment can also be done on a smaller pitch circle diameter, as the connection point 28 from engine block 2 and gearbox block 3 ,

To the carrier element 26 To screw on the engine block, are recesses in the driver pot 9 and the flexplate 8th in the embodiment according to 2 intended. The remaining features of the embodiment according to 2 the double clutch 1 with fixed bearing arranged on the motor side 25 correspond to those related in 1 described embodiments. For clarity, therefore, are in 2 only the most essential reference numerals are given, wherein the reference numeral 31 for the at least one recess in the driver pot 9 and the reference numeral 32 for which at least one recess in the flexplate are supplemented.

In the embodiments of the double clutch 1 with motor-side arranged fixed bearing according to 1 and 2 is the fixed bearing arranged on the motor side 25 arranged radially outside of a crankshaft flange. However, this positioning radially outside of the crankshaft flange requires a relatively large bearing diameter. Furthermore, engines are known in which the crankshaft flange terminates relatively flat with the engine rear wall and thus the bearing is not in the context of the 1 and 2 shown position can be arranged. 3 shows an embodiment in which an intermediate piece 33 on the crankshaft 4 is screwed. With the help of this on the crankshaft 4 screwed intermediate piece 33 can the motor side arranged fixed bearing 25 also in front of the crankshaft 4 be positioned. Through the intermediate piece, the bearing can be moved not only in the axial direction, but the bearing can also be arranged radially inside or outside of the crankshaft flange.

To realize this, is the support element 26 for the embodiment according to 3 compared to the explanations after the 1 and 2 modified. According to the in 1 and 2 shown embodiments, the support member 26 an annular portion which is bolted to the motor housing and partially or completely abuts this, and a cylindrical portion which is axially aligned and engages around the bearing inner ring of the fixed bearing. The annular region and the axially aligned cylindrical region of the carrier element are in this case welded together. Between the annular region and the axially aligned cylindrical portion is in addition to the position trough ring to which the spring element 28 recorded and supported. Instead of the annular region, at least one longitudinally extending region (comparable to one or more mounting lugs) may be provided, around the carrier element 26 to be attached to the engine block or gearbox block. The annular region or region can also be biased against the motor housing, so that a force acts on the support point, whereby the rigidity of the support element is increased.

In contrast, the carrier part has 26B according to 3 an only comparatively short annular area or a comparatively short longitudinal extent on the engine block 2 is applied, which is continued by a radial region extending at an angle from the engine block 2 removed and opens into an axially aligned cylindrical portion which is connected to a bearing outer ring of the fixed bearing 25 is applied, the bearing outer ring of the fixed bearing 25 between an end region of the axially aligned cylindrical region of the carrier element 26B and one with the carrier element 26B connected bearing cap is held.

The bearing inner ring of the motor side arranged fixed bearing 25 is with the driver pot 34 connected, which radially inwardly has a recess to which the bearing inner ring is attached and secured with a retaining ring.

In accordance with another aspect of the present disclosure (which may be used in conjunction with or separately from the remaining aspects of this and the other embodiments), both the bearing inner race and the outer bearing race are the fixed bearing 25 axially as well as radially fixed to the carrier element 26B and at the driver pot 34 appropriate. The radial degree of freedom is determined according to the in 3 shown embodiment at the connection point 35 of the carrier element 266 to the engine block 2 realized.

For this purpose, the connection point 35 a washer 36 on which one or more screw (s) 37 screwed to the engine block. The washer 36 has at least one recess 36A on, in softer the motor-side end of the support element 26B intervenes. The motor-side end of the support element 26B can now be in between the intermediate disc 36 and engine block 2 formed groove 38 move smoothly.

Especially from a comparison of 1 and 2 on the one hand and the 3 on the other hand, it becomes clear that the radial compensation point between motor-side fixed bearing 25 and motor housing 2 (or gearbox housing 3 ) at any point of the bearing connection between the fixed bearing 25 and the engine block 2 can lie.

In addition, a further radial compensation point between the fixed bearing 25 and the actual double clutch (central plate) are.

Another possibility to realize the radial degree of freedom is the fixed bearing 25 Even if its structure can compensate for a sufficiently large radial offset, can be dispensed with one or both externally arranged balancing position.

The variants described above for generating the radial degree of freedom are also combinable with each other to the radial degree of freedom to increase.

That under the 1 and 2 described assembly concept can also be applied to the embodiment of the double clutch 1 with fixed bearing arranged on the motor side 25 according to 3 be applied, it comes only the intermediate piece 33 Add that to the crankshaft 4 must be connected before the connection and storage components on the engine block 2 be attached.

In addition, in all embodiments between drive shaft 4 and Flexplate (or similar connection) or between intermediate piece 33 and flexplate 8th (or other axially elastic and radially rigid connecting element) a support element 33A be arranged, which is the power flow between the drive shaft 4 and ensures coupling.

The storage concept described above, in particular for a double clutch, can be adapted to a large number of dual clutch types (wet and dry). A corresponding example is in 4 shown.

In the double clutch according to 4 with a drive and a driven side actuator, the motor side arranged fixed bearing 25 over the clutch cover 36 the motor-side coupling with the central plate 12 get connected. The remaining features of the embodiment, especially with regard to the storage concept correspond to in 1 shown.

For the installation of such a double clutch to 4 the motor-side coupling must be disconnected from the central plate. This motor-side (partial) coupling is fastened to the engine together with the connection and mounting components. After the gearbox with the provisionally fixed transmission-side (partial) coupling is mounted on the engine block, the two partial clutches are reconnected to a double clutch.

4 In addition, an embodiment of the fixed bearing connection can be removed, in which a radial degree of freedom on the bearing inner ring and a further radial degree of freedom are provided on the bearing outer ring. This degree of freedom can also be combined with all other types of degrees of freedom education.

at all embodiments are muted or undamped Clutch discs usable.

The above description discloses in particular a storage concept for a double clutch with a fixed bearing, the motor side of the central plate 12 is arranged and receives axial forces and tilting moments of the clutch. By at least one radial degree of freedom of the fixed bearing or the bearing connection radial forces are supported on the crankshaft. Thus, a tension between the fixed bearing and the crankshaft bearing in the radial direction is excluded. Axial and wobble movements of the crankshaft flange as well as axial tolerances are compensated by a flexplate (or another elastic connection).

by virtue of The present type of load as a bearing in particular rolling bearings, such as deep groove ball bearings, four-point deep groove ball bearings, four point bearings, double-row angular contact ball bearings or double row thrust bearing well suited. The fixed camp can be off a single bearing or several bearings, preferably side by side are arranged, and possibly also necessary fasteners for securing the fixed bearing property, such as circlips.

The The above description shows a possibility of (double) coupling store on the motor side and the axis of rotation of the coupling coaxial with Align crankshaft. As a result, there are no compensation elements for the Axial offset between motor and coupling required. The misalignment occurs then between the clutch and the transmission and can by clutch discs and the elasticity the transmission input shafts are compensated.

Would the Clutch rigidly mounted on the crankshaft, as it has long been According to the prior art, the operating forces of the clutch on the other hand transferred to the crankshaft bearings. These actuating forces are with double clutches quite high and act over a comparatively long time Time. In contrast, The axial actuating forces are added the present teaching a fixed bearing (rolling bearing) supported. Thus, a storage for Clutches (especially dry double clutches) presented, the without consuming Additional element with the axial offset between the engine and gearbox rightly comes.
