Shape likes.Second contact area 7b is formed by the ring week region on cylindrical surface 39.Cylindrical surface 39 as that can see in fig 1 and 2
As with its longitudinal direction/longitudinal extension part along central axis 9 radial direction stretch.Second contact area 7b/ cylinder
Face 39 radially can be relatively movably contained in the hole 26 (also referred to as long hole) correspondingly shaped.Therefore second matches
The hole 26 for closing contact area 8b forms guide rail 10, and the second contact area 7b radially can be guided movably along guide rail.Cause
This, the second single-piston 4b is permanently connected along ring circumferential direction/rotation direction and load-carrying unit 6 about central axis 9/in carrying member
Support/receiving on part 6, however can relatively movably be accommodated relative to load-carrying unit 6 along the radial direction of central axis 9.As a result,
Cylindrical contact portion is realized between the cooperation of the second contact area 7b and second contact area 8b.It can also according to other embodiments
It is capable, and the second contact area 7b is constituted according to the first contact area 7a or contacts second contact element 13b with first
Element 13a is configured to ball on the whole in the same manner.
In this regard, the second cooperation contact area 8b's is used to connect lug boss 33 as can be seen in figure 16 and 17
Corresponding receiving hole 34 long hole is configured to according to mobility radially.
Third single-piston 4c is illustrated in detail in conjunction with Fig. 9 and 10.Third single-piston 4c is equally single living according to first in principle
4a construction is filled in, therefore for the terse difference only described between single-piston 4a and 4c below.Form third contact area
The third contact element 13c of 7c is shaped differently with first contact element 13a again.Third contact element 13c has half of spherical surface
27, third contact element by means of half of spherical support on support component 15 (Figure 15).Third contact area 7c is formed in again
It is towards on the side of load-carrying unit 6.Third contact area 7c flatly shapes/is configured to flat face 35.The flat face
35 (replace with 40 face formula contact of the mating surface/face contact on the equally substantially level land/flatly constitute of third cooperation contact area 8c
Selection of land, point contact or line contact are also feasible).Thus third contact area 7c and third cooperation contact area 8c are in contact plane 11
Middle contact.Therefore third contact area 7c is allowed about central axis 9c not only radially but also along ring circumferential direction
(inside contact plane 11) can be moved relative to third cooperation contact area 8c.
In order to ensure the movement, receiving hole 34 is accordingly constituted greatly.However in order to ensure cooperating with the shape of holder 12
Connection, as in Fig. 1 it is good it is visible as, be mounted with the additional fixing element 36 in fixed plate form.Fixation member
Part 36 equally has receiving hole 34, and the receiving hole vertically supports convex with 33 collective effect of lug boss and in the mounted state
Portion 33 is played, is movably coupled with load-carrying unit 6 so that the holder 12 of third single-piston 4c is anti-.
Fig. 2, Figure 18 and Figure 19 are returned to, it is also proposed that, holder 12 has window 37 in support region 32 about holder 12.
The window 37 is configured to, so that window is for realizing mistake proofing connection.The window 37 is designed and sized to, so that especially second connecing during installation
Element 13b and third contact element 13c is touched relative to the relative rotation position of piston matrix 14 and load-carrying unit 6 and along diameter
It is introduced into correct position to the orientation in direction.
In other words, three piston disconnector (secondary cylinder 1) formed according to the present invention, three piston disconnector are for sub- clutch
A part of the manipulation device of K1.Equally exist the manipulation device for sub- clutch K2.According to the present invention based in hydraulic work
Three contact portions between plug system (single-piston 4a, 4b, 4c) and the loading plate 6 of bearing (the first manipulation bearing 5) realize movement
The design of aspect is learned, the radial misalignments compensation of bearing is located on the loading plate.Therefore piston 4a is equipped with spherical contact portion.
Second piston 4b is equipped with cylindrical contact portion, and wherein lateral surface 39 is radially shown outward.Third piston 4c is arranged
There is plane, linear or dotted contact.Contact point 1 and 2 (first and second contact area 7a, 7b) can be regarded as convex respectively
It is shape and spill.Therefore ball contact is made of ball, and the ball bond is in the spherical recess portion 26 of loading plate 6.Equally,
Contact portion 2 is made of cylinder, and the cylinder is bonded in the cylindrical recess portion 26 of loading plate 6.Only in contact portion 3, (third is connect
Touching region 7c) it is in the fit shapes that spill is abandoned in loading plate 6.Here, considering line contact, point contact or face contact.
More piston system K1 (first piston unit 3) are divided into three piston components (single-piston 4a, 4c, 4c).Thus exist
Ensure in the case where optimal positioning: engagement bearing K1 reaches always or in most cases the center of rotation of clutch.Here,
It is considered as interfering by the effect that the unknown friction valve between different components, different thermal expansions and tolerance obtain
Amount.Therefore also suggest following kinematics scheme: the contact portion equipped with floating when clutch and outer ring K1 are contacted, the floating
Contact portion only preload load via clutch under unsteered state.When release bearing 5 and loading plate 6 contact,
It is proposed the contact portion (radial misalignments compensation) pre-tightened.When loading plate 6 and piston 4a, 4b, 4c contact, propose less stationary is
System.The system is made up of ball contact, and in ball contact, piston 4a bearing ball, the ball bond is in loading plate 6
In corresponding shape in.The contact portion positions loading plate 6.Inclination and rotational freedom do not determine also.The system passes through cylinder
Shape contact portion is constituted, and lateral surface 39 radially protrudes outward (wei β t).The contact portion determines the freedom degree of rotation.?
It is contemplated that ball, the ball stretch in cylindrical face.The system is made up of the contact portion of plane, which, which eliminates, is
System tilts and blocks last freedom degree.Herein also it is contemplated that point contact or line contact.
This set generates following characteristic in three or more pistons of application, and the characteristic can be with common CSC
Similar, it is self-centering in center of rotation that this is related to bearing 5.By quasi-static characteristic, or by being connect in loading plate 6 with piston
Approximation determines that friction valve is 1 (blocking) when touching, which occurs on the position being arranged thus: in the radial wrong of bearing 5
In the compensation of position.
Realize from contact area 7a to 7c and with contact area 8a is constituting to 8c, quasi-static contact portion, so as to one
Aspect defined position, bearing 5 can reach its position in the position.To this it is required that at the time of contact for eccentric power
Greater than the power when radial misalignments are compensated for bias.Meanwhile manufacturing tolerance compensation is needed in contact portion 4 and is used for possible
The compensation of different thermal expansions.In this regard, by a/b/c (contact portion that 7a to 7c and 8a to 8c) are constituted provides necessary freedom degree,
Although its corresponding blocking for the self-centering expression contact portion of bearing 5.Therefore corresponding in thermal expansion or when tolerance compensating
Single contact portion in match.Spherical contact portion (the first contact area 7a with the first cooperation contact area 8a) is always
The radial position of restriction system.It for example makes load-bearing part 6 relative to loading plate 6 when expansion (temperature) occur in shell 2 (plastics)
(steel) is eccentric.The expansion or bias are kept out by other contact portions.Therefore, the contact portion is (with the second cooperation contact area 8b's
Second contact area 7b) only determine loading plate 6 the circular orientation via cylindrical body.But the radial position of cylindrical body is not stopped
It sets, but its open radial position, so that reaching new position in cylinder inflation.Cylindrical face in loading plate 6
In the case where angled error, the piston 4b of contact portion 7b is carried by slight rotation compensation angular error, but cylinder
Body shows greatly its Angle Position orientation in piston 4b.Contact portion 7c (the third contact area with third cooperation contact area 8c
7c) for theme thermal expansion show no sign of stop movement because it only plane earth reclines.When compensating thermal expansion, ball is corresponded to
Contact portion, such as bearing 5 and loading plate 6 pull out from center of rotation together.However when manipulating next time, bearing 5 is in clutch
Reach its position via radial misalignments compensation again in the center of rotation of device.
Furthermore it mentions, component 13b and 13c is respectively provided with the shape of ball on its side towards piston, this is realized pair
Identical component 15 is used respectively in all contact portions, and is realized and compensated in systems slight in the ball contact
Angular error feasibility.In addition, via four possible rake joists of column (columnar region 29) limit in component 14 (piston)
Gap.These columns 29 are preloaded lotus at runtime or are squeezed by the pressure in pressure chamber towards loading plate 6 in manipulation.When present
When tilting, these columns 29 encounter loading plate 6 according to embodiment, or encounter as realized here and stick on carrying
Component 12 on plate 6.Thus power is generated, the power acts on the contrary with tilting force and prevents to tilt.In shown modification
In scheme, preloads and applied on this system by clutch.This preloads and is sequentially supported at shell 2 below via component
It is upper: bearing K15 → 6 → component of loading plate 13a, 13b, 13c → 15 → piston of support plate (piston matrix 14).In pressure-loaded
When, via sealing element and piston applied force in reverse order.
