Background technology
This clutch apparatus is known by patent DE10350573A1.
The document discloses a kind of double clutch device for automotive transmission.It comprises two lamella clutch, it
Be made up of together with the disc group attached troops to a unit respectively interior disk holder and outer disk holder respectively.Two lamella clutch are coaxially
And arrange radially adjacently.The interior disk holder of the lamella clutch of radially outer and the lamella clutch of radially inner side
Outer disk holder is integrally designed to common disk holder.This disk holder is designed as basin shape, and wherein its tub wall removes
Also there is the interior teeth portion being directed radially inwardly toward at this, the clutch of this interior teeth portion and inner radial outside unessential outer toothed portion
Outer disc outer toothed portion coordinate, but outer disc is the most axially displaceably bearing in disk holder.Footpath is inside
The disc group of the disc clutch in portion utilizes operation piston on-load pressure vertically and supports at opposite side vertically in side
On non-yielding prop ring, self backstop of this support ring is on the dead ring being designed as tightening hoop.Dead ring is located at inner side cincture
In the groove of the tub wall of disk holder, in the tooth top that the incision of this groove is prominent respectively inwards.The diameter of dead ring the most so sets
Put size so that the slot between its two teeth of suspension ground bridging, the most described groove is by only present in the region of tooth top
Teeth portion section the most associatedly forms.By the supporting spring being designed as diaphragm spring between the disc of disc group, disc group exists
Side is elastic to be bearing in support ring (namely dead ring) and is being bearing on operation piston at opposite side the most tightly.Dead ring
On the most outer joint-cutting wall of the joint-cutting therefore abutting in whole groove section.Dead ring abuts in axially leaning on of groove section
On outer joint-cutting wall, described groove section is referred to here as supporting groove section.In known clutch apparatus, whole
Groove section is configured to supporting groove section.This is existing problems when considering the conventional manufacture method of this disk holder.In order to
Make for reasons of weight and manufacturability the thinnest tub wall be stablized, the most described joint-cutting generally will not, such as by
Rotary cutter cuts out described joint-cutting in tooth top.It is true that the composition of described joint-cutting is entered by so-called fluting (Einstiche)
OK.To this end, multiple be respectively fan-shaped, combine conglobate knife rest and guide disk holder vertically into.Each knife rest is at it radially
Have on outer side and be parallel to the cutter of disk orientation and in its most inner side, there is startup inclined-plane.All
The inclined-plane that starts of knife rest collectively forms the recess of taper, and the drift of corresponding shaping is introduced in this recess, for by these knife rests
Elapsing the most radially outwardly, the most described cutter incision tooth top and the panel material separated are transformed into bent outward

Ground, namely in same grooving step, produce desired joint-cutting.Only a part tooth top, logical in single grooving step on the contrary
Often produce joint-cutting every a tooth top.But grooving tool is replaced and by the facewidth of turning over of relative configurations afterwards
Instrument replaces, and can implement the second grooving step by this instrument, is used for making other tooth tops produce joint-cutting.Alternatively can use
So-called transfer tool, the most only uses a new tool level.In both of these case disadvantageously, tool changing or work
Tool transfer frequently results in the trickle position difference of the joint-cutting made in different grooving step in practice.Described joint-cutting, enter
And for the bearing-surface of dead ring thus without being positioned in identical plane, therefore in joint-cutting, the dead ring of press-in is wavyly
Deformation.This can cause the instability in the moment transmission of clutch apparatus and especially cause less desirable system vibration.
Summary of the invention
The technical problem to be solved is, so improves this type of clutch apparatus so that the perseverance of moment transmission
Qualitative it is enhanced.
Described technical problem solves by a kind of clutch apparatus, and it comprises the first lamella clutch, this first chip from
Clutch has:
Disk holder in-the first, in one group first, disc is axially displaceably arranged on first in disk holder,
-the first outer disk holder, one group of first outer disc vertically with first in disc alternately, axially displaceably set
Put in the first outer disk holder, and
-one group first supports spring, and the disc of least one set the first disc is the most elastic by described first supporting spring
Ground supporting,
Wherein, in first, disc, the first outer disc and the first supporting spring collectively form the first disc group,
And wherein,
-one disk holder peviform ground molding also has tub wall, and this tub wall has that be distributed on its circumference, radially-inwardly
Point to, axially extend the tooth beyond tub wall height, and
-the first dead ring is set the axial stop as the first disc group, this first dead ring in the first groove
Inner side is around tub wall, and described first groove is made up of multiple first groove sections, and described first groove section is as circumferentially indulging
Long the first joint-cutting extended is arranged in the tooth top of tooth, and wherein the first dead ring is based on the first disc group by the first supporting spring
The initial tension of spring produced abuts in each two joint-cutting of some the first groove sections being used as the first supporting groove section respectively
On a joint-cutting wall in wall so that the first dead ring is passed through being circumferentially arranged at the first supporting groove section (Anlage-
Nutabschnitt) between and be used as first passage groove section (Passage-Nutabschnitt) other first
Groove section and do not contact with joint-cutting wall.
Preferably form of implementation is drawn by the technical scheme of dependent claims.
The present invention based on cognition be, it is not necessary to all of groove section firmly supports dead ring.In theory three
Individual supporting-point is sufficient for determining the position of ring.But this is inadequate in practice, because dead ring is transported at clutch apparatus
Bearing obvious pressure during row, this pressure can cause dead ring to deform when supporting is insufficient to.On the other hand it is a discovery of the invention that be
Stability needed for providing, the most complete supporting of dead ring or the supporting in whole groove sections are to need not
's.By the present invention, supporting-point be reduced for groove section a part, being especially reduced to can be by the most common manufacture
Those groove sections made by process.It is typically one of two groove sections.The remaining channel groove section of being referred to as
The most inapplicable and tightened relative ring the thickness of groove section goes out greatly certain proportion, and therefore dead ring does not contact theirs
Joint-cutting wall.
Therefore as mentioned above in terms of joint-cutting location, it only occurs in the height position of each joint-cutting wall of supporting groove section
Putting, support ring abuts on joint-cutting wall in assembling end-state.The width of the opposed position of joint-cutting wall, namely joint-cutting
It is largely unessential, as long as dead ring is positioned in joint-cutting.Generally, the most for stability reasons, supporting groove portion
The joint-cutting of section can design size as small as possible, in terms of its width, be namely substantially equal to the thickness of dead ring.The most excellent
Choosing regulation, the width of slit of channel groove section is more than the width of slit of supporting groove section.Therefore it is accomplished that, channel groove
The joint-cutting of section offset along the supporting direction of dead ring relative to supporting groove section and leave for dead ring simultaneously enough
Space, therefore dead ring will not contact channel groove section joint-cutting wall below, but recessed through passage contiguously without wall
Groove section.
Technical staff is it is to be understood that the contacting of bottom land of dead ring and groove section (supporting or channel groove section)
Do not affect the effect of the present invention.
The present invention is largely independent of the special tectonic of clutch apparatus.It especially advantageously can have only one
The simple clutch apparatus of individual lamella clutch is applied.But the present invention particularly advantageously has the cloth that axially adjoins each other
Use in the case of the double clutch device of the lamella clutch put.In this double clutch device, two lamella clutch
Outer disk holder be made up of integral type, benzvalene form, common disk holder constitutes.This disk holder must have at least two
The individual groove for fixing two dead rings, namely for each lamella clutch, there is at least one groove.To this end, each list
The relative localization of the groove section of only groove and the mutual relative localization of two grooves must be carried out with the highest precision.
In the preferably extension design of the present invention, the above-mentioned principle reducing supporting-point is applicable to each of each dead ring independently
Groove, but wherein in reality manufactures, all joint-cuttings should being arranged in tooth are by unique manufacturing step, especially slot step
Suddenly make.In detail, the present invention in terms of double clutch device favourable application it is meant that with aforesaid according to the present invention's
Based on single clutch device, also include that the second lamella clutch, described second lamella clutch have
Disk holder in-the second, disc in axially displaceably arranging a group second in disk holder in described second,
-the second outer disk holder, described second outer disk holder is constituted and in institute with the first outer disk holder integral type
State axially displaceably arrange in the second outer disk holder vertically with second in the outer disc of disc an alternate set second, and
-one group second supports spring, and the least one set disc in the second disc is by described second supporting spring mutually bullet
Property supporting,
Wherein, disc, the second outer disc and the second supporting spring collectively form axially adjacent with the first disc group in second
The second disc group, and wherein the second dead ring is arranged as the axial stop of the second disc group, and this dead ring exists in inner side
Around tub wall in second groove, described second groove is made up of multiple second groove sections, and described second groove section is as edge
Circumference lengthwise extend the second joint-cutting be arranged in the tooth top of tooth, wherein the second dead ring due to the second disc group by second
Hold the elastic pre-stress that spring produces to abut in each two of some the second groove sections being used as the second supporting groove section and cut
On one joint-cutting wall of slotted wall, and the second support ring is not passed through with joint-cutting wall being circumferentially arranged at second concave contiguously
Other the second groove section between groove section and as second channel groove section.
When this principle is converted, two kinds of modification are proved advantageous particularly.First modification specifies, propping up of the first groove
Concave groove section is the same with the supporting groove section of the second groove to be arranged on identical tooth.Especially in supporting groove section with logical
In road groove section dentation ground form of implementation alternately, this channel groove section also meaning that the first groove and the second groove
Channel groove section is arranged on identical tooth.In this modification, support teeth and passage tooth are different in terms of the flank of tooth.For system
Make process it means that the highest precision, adding of contrary passage tooth must be kept in the common processing of all of support teeth
Work can be carried out with relative coarseness and with having bigger width of slit.
Specify on the contrary in another kind is also regarded as favourable modification, the supporting groove section of the first groove and second recessed
The channel groove section of groove is equally arranged on identical tooth.Especially hand at supporting groove section and channel groove section dentation

Put on identical tooth.In this modification, each tooth had both carried a channel groove section and had also carried a supporting groove portion
Section.The most all of tooth must be with identical precision processing.But described precision adds with the support teeth in above-mentioned first modification
It is to reduce, because the relative localization at these two grooves need not be considered in same procedure of processing that the manufacture of work is compared.Instead
And, in the accurate manufacturing technique step process of the first groove, namely in the manufacture process of its supporting groove section, the second groove
Location the most cursorily namely is considered in the category of the manufacture of its channel groove section.Vice versa, in the essence of the second groove
In the category of degree manufacturing step, the position of the first groove is only roughly considered.
As sufficiently known in prior art and the above, it is further advantageous that groove section is passed through in scope of the invention
Being recessed on the tooth of tub wall composition, then the sheet material forming material of described tub wall or its tooth constitutes bend radially outward stable bridge
Frame.
