Clutch, the seal assembly has potted component, and the potted component has the flange segments of an annular, and the flange segments set
There are multiple sealing lips, the sealing lip points to the common radial direction of potted component and respectively constituted and prepares for reclining
Sealing surface on the pressure piston or housing of the pressure cylinder unit, and the potted component has a support ring, the branch
Pushing out ring by the radial side away from the sealing surface of the potted component be supported ground and diametrically with the sealing
Face is arranged in the flange segments at interval.Additionally, the utility model is related to a kind of pressure cylinder unit in itself, the pressure cylinder
Unit is preferably designed for clutch active cylinder (Kupplungsgeberzylinder) or clutch slave cylinder
(Kupplungsnehmerzylinder) and with this seal assembly.
Background technology
The seal assembly of the type is sufficiently known by prior art.Thus, for example DE 10 2,013 200
986A1 discloses a kind of seal assembly of piston-cylinder units, and rising has lip ring, and lip ring has static sealing lip
With motion seal lip, they are connected to each other.The seal is received in an acceptance division, and the acceptance division has at least one circumferentially
Wall portion and at least one axial wall portion, and seal is radially supported at circumferential wall in the acceptance division with static sealing lip
In portion.Motion seal lip is abutted in another wall portion being contiguous on the acceptance division in the case where that can slidably support, and
The axial end portion of static sealing lip can be abutted in the axial wall portion.Additionally, being provided with for reducing seal in static state
The device of the torsion in the axial end region of sealing lip and/or in axial wall portion.
Thus, by seal assembly known in the art, these seal assemblies are especially also used in disconnect-type clutch system
In system.(clutch active cylinder (English is often constructed as especially in the field of these pressure cylinder units：“Clutch Master
Cylinder "/CMC) have proven to disadvantageously, to be situated between using the fluid of relative low value in the use of these pressure cylinder units
Uncomfortable noise may occur during matter by slip against each other of the potted component in corresponding housing or pressure piston to increase
It is long.Especially under about 80 DEG C or more than 80 DEG C of running temperature, this kind of motion artifacts are often produced, these motion artifacts can
Comfortlessly perceived with by the user of motor vehicle.Here, also produced in the range of sealing surface mostly relatively high simultaneously
Friction.
Utility model content
Therefore, the purpose of this utility model is to eliminate by shortcoming known in the art and be provided in particular in a kind of sealing group
Part, the seal assembly will also ensure the noise as no as possible of pressure cylinder unit when in the fluid media (medium) using relative low value
Operation.
According to the utility model, the purpose is realized in the following way：Support ring is in (seal assembly) unloaded condition
Lower taper ground (namely the axial direction of opposing seal component obliquely) is formed with and abut in operation the flange segments
On supporting surface.
Thus, seal assembly abuts in piston or housing so that its flange segments is sealed as homogeneously as possible in operation
On, in the operation, in the radial direction intermediate cavity that seal assembly is compressed between pressure piston and housing with certain pretightning force.
Constructed by the taper of support ring, hence it is evident that noise behavior is improved, because purposefully avoiding under all operating conditions
It is contiguous to the region contact with housing or pressure piston on sealing lip.
The prescription in the dependent claims of other Advantageous embodiments and below explaination in detail.
If flange segments are connected with the matrix of potted component and can be elastically deformed in the radial direction in addition, then institute
Flange segments are stated particularly efficiently to work.
Additionally, in this context it is also advantageous that flange segments and matrix material single type ground/integrally construct.
The potted component is advantageously manufactured thus, it is possible to abnormal cost on the whole.
In addition meet purpose, flange segments by elasticity/plastic material of elastically deformable, for example, be preferably suitable for making
By the elastomer of sealing medium is made, because therefore advantageously have impact on sealing effectiveness.The support ring also advantageously by
Elasticity/plastic material of elastically deformable, such as elastomer, thermoplastic or thermosetting plastic are made.
Also advantageously, flange segments axially extend size aspect and are configured to exist than support ring in an unloaded condition
Its axially extending size aspect (under the unloaded condition) is bigger.Thus avoid：It is preferred that by different from flange segments or close
There is touching in the region in support ring and housing or the region on pressure piston that the plastic material of envelope element is made.In particular by
This avoids the abrasion of support ring material.
When flange segments are supported under the load condition of seal assembly in its whole axially extending size by supporting surface,
Support ring is particularly effectively applied on the sealing lip of all quantity.

Construction/trend, thus, the potted component especially effectively and is stably abutted on pressure piston or housing in operation
In corresponding abutment face.
If supporting surface is constructed/moved towards as follows, i.e. supporting surface is from the matrix of potted component out towards ledge zone
The free end of section go its size/it diametrically becomes big, then particularly effectively realize the sealing.
Additionally, the utility model is directed to a kind of pressure cylinder unit, the pressure cylinder unit has：Housing；With can be described
It is that the mode moved in housing is received and with the housing cross a fluid, preferably the pressure chamber of hydraulic pressure pressure live
Plug；And the seal assembly described at least one in embodiment described before, the seal assembly is with as follows
Mode is arranged so that the pressure chamber is sealed relative to surrounding environment (in fluid, preferably in terms of hydraulic pressure).Thus, it is also special
The pressure cylinder unit is not constructed effectively.
In the case, pressure cylinder unit preferred configuration is clutch active cylinder or is further preferably configured as clutch
Slave cylinder.
It is also advantageous that, flange segments configuration and are supported by support ring as follows, i.e. the flange segments with
The running temperature of pressure cylinder unit relatively changeably abuts in pressure piston by its sealing lip on number and/or the power that reclines
Or on housing.Thus sealing effectiveness relatively can particularly effectively be controlled with the running temperature of pressure cylinder unit.
Also comply with purpose in this context, flange segments configuration and are supported by support ring as follows,
That is, flange segments are when the running temperature of pressure cylinder unit is between -60 DEG C and -30 DEG C, preferably in about -40 DEG C of operation temperature
Under degree, only with a part for these sealing lips by its sealing surface, preferably with two the two of sealing lip sealed patches of sealing surface
Lean against on pressure piston or housing, and at least one other sealing lip (with its sealing surface) is in the running temperature/operation temperature
It is arranged to be spaced apart with pressure piston or housing under degree scope.
It is also advantageous that, flange segments configuration and are supported by support ring as follows, i.e. flange segments are in pressure
