A first friction plate carrier 6 is arranged on the rotor 4, and this friction plate carrier constitutes the input friction plate carrier of the clutch K1 of transmission side.The input friction plate is suspended on this input friction plate carrier 6 of this clutch K1, and these input friction plates axially upper and output friction plate alternately arrange, and these output friction plates are suspended on the output friction plate carrier 7 of clutch K1.At this, hydraulically carry out the operation of clutch K1.
In addition, be provided with the input friction plate carrier 8 of the clutch K2 of driving side at rotor 4, the input friction plate of the friction plate group of minute clutch K2 is suspended on the input friction plate carrier 8.The input friction plate also axially alternately arranges with output friction plate, and output friction plate is suspended on the output friction plate carrier 9 of clutch K2.At this, operated clutch K2 hydraulically.
Compare with the output friction plate carrier 7 of clutch 1, the output friction plate carrier 9 of clutch K2 internally arranges diametrically, has therefore produced radial and axial nested.
Between the output friction plate carrier 9 of rotor 4 and clutch K2, be provided with first thrust-bearing 10.
Between the output friction plate carrier 7 of the output friction plate carrier 9 of clutch K2 and clutch K1, be provided with second thrust-bearing.
Output friction plate carrier 7 and input wheel hub 1 at clutch K1 are provided with the 3rd thrust-bearing 12 in other words between the input block 2.
Between input wheel hub 1 and a lid 13, be provided with a rigid bearing 14.To wet chamber and surrounding environment of lid 13 is that drying chamber is separated, and this wet chamber refers to clutch housing (Kupplungsglocke), is arranged in this clutch housing by the double-action wet clutch of Fig. 1.
The output friction plate carrier 7 of clutch K1 is connected with first transmission input shaft 15 by an axial grafting tooth section, and the output friction plate carrier 9 of clutch K2 is connected with another transmission input shaft 16 by a grafting tooth section.
Between two transmission input shafts 15 and 16 in this coaxial setting, be provided with a radial bearing 17.
Be provided with two radial bearings 18 and 19 between stator 18 and rotor 4, wherein, by this stator 18, hydraulic supply unit leads to the Effector of the hydraulic pressure of clutch K1 and K2.
At this, between the transmission input shaft 15 of inside and input wheel hub 1, be provided with a radial bearing 20 (often being also referred to as " leading bearing (Pilotlager) ").
Therefore, be supported on the stator 18 by radial bearing 18 and 19 by the double-action clutch structure of Fig. 1, and therefore be supported on the case of transmission.In addition, it is bearing on the inner transmission input shaft 15 by leading bearing 20, and towards the live axle of clutch, namely is supported towards input wheel hub 1.By the live axle (namely inputting wheel hub 1) of clutch and an additional lid bearing 14 between the clutch cover 13, whole unit is supported regularly with respect to housing.
In the axial direction, by these three thrust- bearings 10,11 and 12 and by cover support of bearing 14 realizations.
In double-action wet clutch described above, it has the axial nested single clutch of wet type operation, torque is delivered on the rotor 4 and by clutch K1 and K2 and is delivered on output friction plate carrier 7 and 9 by being positioned at outside input alms bowl 2, and is delivered on these transmission input shafts by these (compare be positioned at the friction plate group outside) output friction plate carriers 7 and 9.Because minute clutch K1 and K2's is axial arranged, the outside friction disc carrier 7 round adjacent minute clutch K2 of clutch K1 must constitute " deeply, the form of alms bowl.In other words, produced the parts of a long alms bowl shape, its center of gravity with respect to the supporting in the zone between the outside friction disc carrier 7 of K1 and the transmission input shaft 15, wheel hub tooth section from relatively away from.Because large to the lever arm of its turning point from the center of gravity of outside friction disc carrier 7, this turning point is positioned at driving gear section together with the center of transmission input shaft 15, tumble with respect to transmission input shaft 15 so this friction plate carrier 7 can occur in when operation, and occur to the tumbling of parts (especially with respect to input friction plate carrier 6 and be suspended on the input friction plate of the inside) of the driving side of double-action wet clutch.So, described tumbling according to the tolerance range of these parts may cause outside friction disc carrier or its friction covering with the inner attrition piece carrier or be suspended on the friction plate producing contacting of not expecting there.In the inner attrition piece carrier with the speed discrepancy rotation when this causes friction covering to be embedded in joint and disengagement, or imbed in the inner attrition piece.Therefore can adversely affect the function of clutch.Correspondingly produce thus following task, namely support in this wise the outside friction disc carrier, so that tumbling of it is all so little in each tolerance range, so that it does not contact with the parts that rotate with speed discrepancy.
The possible solution of above-mentioned task is the grafting tooth section of the tooth top centering on the transmission input shaft of inside.This solution only is that cost is high, does not therefore make great efforts in this respect before.In addition, although may use the grafting tooth section of tooth top centering, the gap owing to also having in the tooth section of tooth top centering always also exist the possibility of tumbling, represents by the motion arrow B, has produced again thus the worn area that represents with C.
The below shows, how to this expensive solution alternatively, by between the wheelboss part of the outside friction disc carrier 7 of inputting wheel hub 1 and clutch K1, using the leading bearing of the location that is fated, the radial motion of limiting friction sheet carrier, this radial motion illustrates by the motion arrow B in Fig. 2.
In addition, the below shows with it with replacing it in combination or, the wheelboss part that this task also can be by lengthening outside friction disc carrier 7, especially solves by the grafting tooth section between extension shaft and the wheelboss part.
Figure 3 illustrates shown in figure 2 possible first measure of tumbling of above-mentioned, as to be used for reducing clutch K1 outside friction disc carrier 7.In the embodiment shown in fig. 3, leading bearing 20 no longer between transmission input shaft 15 and input wheel hub 1, but be positioned at clutch K1 outside friction disc carrier 7 wheelboss part 7 ' and input between the wheel hub 1 (live axle of clutch).This has two effects basically for reducing tumbling of outside friction disc carrier 7:
1. by outside friction disc carrier 7 is bearing in the live axle 1, tolerance chain (by direct supporting) has reduced concentricity tolerance, and has reduced the radial clearance of grafting tooth section 21 inside.
2. the transmission input shaft 15 in inside has saved leading bearing, and this has created structure space extraly in the scope of grafting tooth section.This structure space is used to add long splice tooth section.The transmission input shaft of lengthening in inside of grafting tooth section produced the in other words wider supporting base of the wheelboss part 7 ' of friction plate carrier 7 of friction plate carrier 7.Therefore when the radial clearance of grafting tooth section 21 is identical, possible the tumbling of the sheet carrier 7 of can obviously reducing friction.
This measure and following characteristics are combined, that is, the input wheel hub 1 of clutch (by lid bearing 14) radially is supported with respect to speed changer in surrounding the housing of clutch (by corresponding clutch cover 13) regularly.By the further minimizing of consequent radially public chain, in conjunction with the leading bearing of having passed and lid bearing, in case of necessity in conjunction with the possible lengthening of grafting tooth section, stop to the full extent 7 possible the tumbling of outside friction disc carrier.
The lengthening of grafting tooth section also can come to replenish in the following manner, and namely wheelboss part 7 is configured to have the axial overlap X with respect to outer transmission input shaft 16.At last, by this way can be to the full extent with whole design constraints irrespectively chosen axis to the length of grafting tooth section.
Figure 4 illustrates another embodiment of double-action wet clutch, it is substantially the same in the described structure of Fig. 3.As to the replenishing of shown in Figure 3 and described content, except between the leading wheelboss part 7 ' of bearing 20 ' with the outside friction disc carrier 7 of external wheel for inputting hub 1 and clutch K1, also used another leading bearing 20 in this embodiment ".Identical design is therewith, uses a wider leading bearing (for example as rolling body bearing or sliding bearing).By this wider bearing unit, except the radial force that occurs, also can receive tilting moment.Thus, when identical possible the tumbling of the outside friction disc carrier 7 of K1, also may strengthen radial clearance or the rotation sideshake of grafting tooth section of the wheelboss part 7 ' of clutch K1.
The output terminal friction plate carrier that is positioned at the outside of embodiment's described above something in common first minute clutch K1 in the double-action wet clutch of axially setting, wet type operation must center on second minute clutch K2.For this reason, the parts of long alms bowl shape have been produced, its center of gravity is away from the supporting relatively in the zone of wheel hub tooth section, therefore parts are easily tumbled when operation, thus because with respect to the speed discrepancy of parts on every side and owing to can produce wearing and tearing with contacting of parts on every side, these wearing and tearing may adversely affect the function of clutch.These embodiments show, how by between the input shaft of the drive hub of friction plate carrier and clutch, using a leading bearing, and the combining cover bearing can limiting friction sheet carrier radial motion, and tumble by lengthening can limit equally at the grafting tooth minister degree on the transmission input shaft and on the driven wheel hub.
Therefore the carry-out part or the output hub that show highlightedly a clutch pass through the supporting of bearing in the unit of the driving side of this clutch.The unit of the driving side of this clutch is bearing in the housing that surrounds clutch regularly by a relative speed changer of other bearing again.By minimizing tolerance chain radially, and by adding possibly long splice tooth section, limited possible the tumbling of friction plate carrier.In addition, can receive the tilting moment of tandem compound by the bearing matrix of widening (bearing of widening or additional bearing) of leading bearing, therefore when identical tumbling, can reduce the rotation sideshake (Verdrehflankenspiel) of grafting tooth section.
