For particularly preferred embodiment, the invention further relates to a kind of clutch apparatus with the slope actuator.
Background technique
In the prior art, commonly known clutch operating device, wherein using composition to operate disconnect-type clutch
The separation equipment of cylinder is exported for CSC/ concentric clutches.This disconnect-type clutch is for example in 10 2,013 215 737 A1 of DE
Middle disclosure.In addition, the prior art of applicant's known internal, the prior art of the inside not yet discloses and discloses a kind of use
In the slope mechanism of operation clutch.
Therefore, the rolling element slope driver of known mechanical, composition have the rolling element of mandatory guidance from the prior art
Retainer.However, the disadvantage in the known embodiment is: rolling element due in operation deformation mechanism and skidding
And it is different from travelling forward to movement backward, that is to say, that along the movement of the first rotation direction of two slope rings relative to each other
Different from the movement of the second opposite rotation direction along slope ring relative to each other.Therefore occur: rolling element is rolling it every time
Its original starting point is no longer reached afterwards.In terms of run time, this path difference superposition, and therefore lead to rolling element or rolling
The so-called undesirable migration of body retainer.
Summary of the invention
Therefore, the purpose of the present invention is to: disadvantage known from the prior art is eliminated, and a kind of slope is especially provided and is held
Row device, the slope actuator are further improved in terms of its wearing character.
According to the present invention, this is accomplished in that first slope ring and/or the second slope ring sloped region exists
Geometrically be configured to so that synthetically acted in adjustment process between its supporting side walls and rolling element pressure (
In terms of size and/or action direction) in the length of supporting surface by targetedly adjusting/control.Here, pressure is in principle
Can be adjusted to so that it is fully eliminated in a region, i.e., in a region between slope ring and rolling element not
Pressure transmitting occurs.
It is realized by this control of the pressure to be transmitted: will be rolled in operation referring to corresponding rolling element or accordingly
Kinetoplast deflects in its rolling process so that the rolling element especially low abrasion be arranged between the ring of slope.
Other advantageous embodiments illustrate in detail below.
It is particularly advantageous herein: in first slope ring and/or the second slope ring sloped region or upper structure
At benchmark groove (Referenzierkuhle), so that in the case where being arranged rolling element within benchmark groove, rolling element
It is arranged in base position relative to slope ring no pressure.By this base position, each separation process starts from rolling element
Restriction and be always to maintain identical position because the base position is always arranged in rolling element in a manner of not stressing
Place.Therefore the micromotion for causing rolling element or retainer to migrate can not be superimposed, move so that unintentionally rolling element does not finally occur
It moves.
When benchmark groove is connected in the pressure section with supporting side walls of sloped region along sloped region observation
(in the pressure section, the pressure in adjustment process is transmitted between rolling element and slope ring), corresponding sloped region
Especially dexterously constitute.
If expanding the radial and/or axial spacing between the ring of slope relative to pressure section in benchmark groove,
So especially cost low land it can realize benchmark groove.Benchmark groove is shaped preferably as lug boss/portion of arching upward/protrusion.
When first slope ring is configured to inner ring and the second slope ring is configured to outer ring and/or the setting of benchmark groove is the
When in (second) sloped region of two slope rings or upper, the second slope ring can be more simply manufactured.As an alternative also advantageously:

The orientation angle of the action direction of pressure changes in the length of supporting side walls.Particularly, change the action direction and only in pressure
The orientation angle constituted between the radial line radially stretched.The pressure between slope ring and rolling element is distributed in tune as a result,
In the whole length of supporting side walls be during section it is particularly desirable, to avoid the possibility of rolling element and possible retainer
Unintentionally migration.
If orientation angle changes in the length of supporting side walls with the step or infinitely, the pressure distribution acted on can
Especially changeably it is adjusted.
Be particularly suitable for: the surface of the rolling element that reclines of supporting side walls expands in the length of supporting side walls.
Furthermore it is advantageous that: it is observed along supporting side walls, orientation angle is at least three longitudinal regions/sub-portion section/intersection
It is different in domain.Here, orientation angle can increase on three longitudinal regions, preferably increase on all three longitudinal regions, or
Person reduces, and preferably reduces on all three longitudinal regions.Alternative in this, also it is possible that: orientation angle is first from first longitudinal direction
Region increases towards second longitudinal direction region, and then reduces from second longitudinal direction region towards third longitudinal region.Also it is also feasible that:
Orientation angle reduces from first longitudinal direction region towards second longitudinal direction region first, and then from second longitudinal direction region towards third longitudinal region
Domain increases.
Be also advantageous in that: rolling element keeps being spaced relative to each other by means of retainer/roller holder along ring circumferential direction
It opens.Also it is possible that: rolling element is mutually arranged in a manner of no retainer.

Illustrate the second embodiment of slope actuator 1 according to the present invention in conjunction with Fig. 6 to 10.Herein it may be noted that
Be: the principle embodiment of the slope actuator 1 of second embodiment corresponds to the embodiment party of the slope actuator 1 of first embodiment
Case.Therefore, in order to brief, the difference between the two embodiments is hereinafter only inquired into.
In addition it should be pointed out that: even if the invisible benchmark groove 8 in Fig. 6 to 8, however the benchmark groove can
Implement according to first embodiment.
The section of first slope ring 2 implemented in fig. 8 to 10 is on the basis of Fig. 6 and 7.In a second embodiment, first
Each first slope region 6 of slope ring 2 is configured to, so that closing during adjustment process between supporting side walls 5 and rolling element 4
Targetedly changed in the length of supporting side walls 5 at the pressure that ground acts on.Particularly, in this embodiment, pressure
Size be kept substantially in the length of 2/ supporting side walls 5 of sloped region it is identical, however the action direction 12 of pressure change.
It is visible in fig. 8: first slope region 6 in the section (cross section in first slope region 6) observation by its
Support side wall 5 in longitudinal region 20 with the first curved surfaces is supported on rolling element 4, and the curved surfaces follow rolling
The surface of body 4.By the surface, the pressure to be transmitted between first slope ring 2 and rolling element 4 (support force) is along what is drawn
Action direction arrow 12 medially acts on a surface.The action direction 12 of pressure is relative to reference line, herein for radially
The radial line 17 of direction stretching, extension has orientation angle α 1.
Then, as combined Fig. 9 and 10 visible: the orientation angle changes in the length in first slope region 6.According to figure
In the second longitudinal direction region 21 of 9 6/ supporting side walls 5 of first slope region, it is fixed to be equipped between action direction 12 and radial line 17
Parallactic angle α 2, the orientation angle are configured to be greater than angle α 1 herein.
Vertical according to the third on the side in first longitudinal direction region 20 that second longitudinal direction region 21 is arranged in of Figure 10
Into region 22, the orientation angle between action direction 12 and radial line 17 has than at second longitudinal direction region 21 (α 2) and first
Bigger orientation angle α 3 in longitudinal region 20 (α 1).
However, orientation angle α 1, α 2 and α 3 can also be constituted in another manner in principle.Two orientation angle α 1 and α 2 can
Greater than α 3.In addition, orientation angle α 2 can also be greater than two orientation angle α 1 and α 3.Orientation angle α 1 can also be greater than orientation angle α 2 and α 3
Deng.
In a second embodiment, preferably each first slope region 6 is with each herein in order to which general view is not shown further
Second sloped region 7 composition has orientation angle α 1, α 2 and the α 3 changed in the length of corresponding sloped region 6,7.However principle
It is upper it is possible that: only a other sloped region 6 or 7 is equipped with orientation angle α 1, α 2 and the α 3 or sloped region 6,7 of this variation
It constitutes differently from one another.
In other words, according to the present invention, especially propose that two kinds are used for rolling element in rolling element slope driver (slope actuator
1) measure of ground movement is limited within.
First measure is related to benchmark groove 8.Here, providing the feasibility on the basis of itself for rolling element 4.If referred to
Rolling element 4 does not stress at specific position then realizing.Whereby, each separation process/adjustment process starts from rolling element 4
Limit and be always to maintain identical position.The micromotion for causing rolling element or retainer to migrate is not superimposed, and is not sent out correspondingly
Green-ball migration.Being in figures 1 and 3 for the rolling element 4 of ball in the illustrated case will go into benchmark groove 8.
Here, entire (pressure) power is also directed on the driver of slope via ball 4.The centering warp of two slope rings 2,3 (inside and outside)
It is felt relieved by the side wall of slope 2,3 or ball 4 to carry out.Ball migration can be carried out from the position.In figures 2 and 4, ball 4 is located at
In groove 8.Therefore, ball 4 and system " slope driver " are decoupled.Other than gravity and the possible caused power by vibration,
It is acted on ball 4 without others power.Now, friction cone 10 undertakes the centering of two slope rings 2,3.Whereby, ball 4 is with itself
On the basis of and in subsequent separation process since the point of restriction, the point is always identical.Before the possibility of ball 4 passes through
Separation process caused by micromotion by before subsequent separation process set benchmark and zero setting.
Second measure is related to the contact angle (orientation angle/pressure angle) of variation.The theory being based on to this is with slope driver
Based on, the slope driver is operated via lever and then Lateral Force is on the slope driver, therefore described
Slope driver, which has by each arbitrary operation angle to the different power on rolling element, to be distributed.Upward tool is walked on entire slope
There is the running track of unique contact angle (orientation angle/pressure angle) so far in ideal conditions only (along sloped region
Domain) reach its perfect condition in specific point in running track, i.e., when the preset rolling of geometry for passing through running track
When kinetoplast position is with by being distributed preset rolling element position consistency to the power on ball, just reach its perfect condition.All its
During he puts, is not matched so far by the preset contact angle of the geometry of running track and pass through transverse direction on rolling element
The distribution of power caused by power.In other words: in terms of geometry, rolling element being forced in following position, the rolling element is originally
Do not entered in the position by dynamic balance or power distribution.For the contact angle/orientation angle and power relative to each operation angle
Balance is consistent, needs following running track (sloped region 6,7), the running track shows connecing for variation via operation angle
Feeler.The variability can be each slope 6,7 identical, or each slope 6,7 is different.Fig. 8 is shown
The first contact angle α 1 under first operation angle.The contact angle can be using arbitrary value.Fig. 9 shows under the second operation angle
Two contact angle α 2.Second contact angle α 2 can be greater than 0 and be less than the arbitrary value of α 1.In shown example, α 2 is greater than α
1.Figure 10 shows the third contact angle α 3 under third operation angle.Third contact angle α 3 can be greater than 0 and less than α's 1 and α 2
Arbitrary value.In shown example, α 3 is greater than α 2.Between the section shown in instances, it can have with any contact
Any more other section (=operation angle) at angle.In addition, variable contact angle can be phase for whole running tracks 6,7
With, but each running track 6,7 can be unique.It can be considered that all feasible angle combinations, it may be assumed that 1 < α of α 2 <
α3；α1>α2>α3；α1<α2>α3；Or 1>α of α, 2<α 3.
Also it can be considered that the combined rolling element slope with the first measure or the second measure or the first and second measures is driven
Dynamic device 1.
