Background technique
This clutch apparatus is as known to patent DE10350573A1.
The document discloses a kind of double clutch devices for automotive transmission.It includes two lamella clutch, it
Be made of respectively interior disk holder and external disk plate rack together with the disc group attached respectively.Two lamella clutch are coaxially
And it arranges radially adjacently.The lamella clutch of the interior disk holder and radially inner side of the lamella clutch of radially outer
External disk plate rack is integrally designed to common disk holder.The disk holder is designed as basin shape, and wherein its tub wall removes
Also there is except unessential outer toothed portion the interior teeth portion being directed radially inwardly toward, the clutch of the interior teeth portion and inner radial herein
Outer disc outer toothed portion cooperation, therefore outer disc torsionally but be axially displaceably supported in disk holder.Diameter is inside
The disc group of the disc clutch in portion utilizes operation piston on-load pressure and along axial direction in another side bearing in side along axial direction
On non-yielding prop ring, itself backstop of the support ring is on the dead ring for being designed as tightening hoop.Dead ring be located at interior side ring around
In the groove of the tub wall of disk holder, groove incision is respectively inwards in tooth top outstanding.Therefore the diameter of dead ring is set in this way
Size is set, so that the slot between its two tooth of suspension ground bridging, therefore the groove is as only present in the region of tooth top
Teeth portion section does not form associatedly.By the bearing spring for being designed as diaphragm spring between the disc of disc group, disc group exists
Side elasticity is pre- tightly (namely dead ring) and to be supported on operation piston on being supported on support ring in the other side.Dead ring
Therefore on the outer joint-cutting wall of the axial direction for the joint-cutting for sticking on whole groove sections.The axial direction that dead ring sticks on groove section is leaned on
On outer joint-cutting wall, the groove section is referred to here as supporting groove section.In known clutch apparatus, therefore whole
Groove section is configured to supporting groove section.When considering the common manufacturing method of this disk holder, there are problems for this.In order to
So that tub wall usually very thin for the reason of the weight and manufacturability is stablized, then the joint-cutting usually will not, for example by
Rotary cutter cuts out the joint-cutting in tooth top.In fact, the composition of the joint-cutting by so-called fluting (Einstiche) into
Row.For this purpose, it is multiple be respectively it is fan-shaped, be combined into circular knife rest and guide disk holder into along axial direction.Each knife rest is in its radial direction
There is starting inclined-plane with the cutter for being parallel to disk orientation on outer end side and in its radial inner end side.It is all
The starting inclined-plane of knife rest collectively forms the recess of taper, and the formed punch of corresponding shaping is introduced into the recess, is used for these knife rests
It jointly radially outwardly elapses respectively, therefore the cutter cuts tooth top and is transformed into bent outward by isolated plate material
Bent stabilization gantry.But for stability reasons, each tool holder designs must be wider than single dental transition.Therefore institute is with teeth cannot be simultaneously
Ground namely generates desired joint-cutting in same grooving step.The only a part tooth top, logical in single grooving step instead
Often joint-cutting is generated every a tooth top.Later grooving tool be replaced and by relative configurations but turn over a facewidth
Tool replaces, and the second grooving step can be implemented by the tool, for making other tooth tops generate joint-cutting.Alternatively it can be used
So-called transfer tool, wherein a new tool level is used only.In both cases the shortcomings that is, tool changing or work
Tool transfer frequently results in the subtle position difference of the manufactured joint-cutting in different grooving steps in practice.The joint-cutting, into
And therefore the bearing surface for being used for dead ring will not be located in identical plane, therefore the dead ring being pressed into joint-cutting is wavyly
Deformation.This will lead to the instability in the torque transmitting of clutch apparatus and especially leads to undesirable system vibration.
Summary of the invention
Technical problem to be solved by the present invention lies in improve such clutch apparatus, so that the perseverance of torque transmitting in this way
It is qualitative to be enhanced.
