Description

SEALING SYSTEM AND MOTOR VEHICLE COMPONENT WITH

SEALING SYSTEM

The invention relates to a sealing system, in particular a sealing system for sealing against hot gas, for example exhaust gases from an internal combustion engine.

For example, the sealing system is a metallic sealing system.

In particular, the sealing system is a sealing system for automotive applications. In particular, the sealing system is provided for an exhaust system and / or part of an exhaust system, the exhaust system being in particular an exhaust system for exhaust gases from an internal combustion engine.

For example, the sealing system is provided for a turbocharger or part of a turbocharger. In some embodiments, the sealing system is provided for or part of an exhaust manifold.

The invention thus also relates to a motor vehicle component having a

Sealing system, in particular one of the components mentioned above with a sealing system.

The object on which the invention is based is to provide an improved sealing system.

According to the invention, this object is achieved by a sealing system, in particular a sealing system for sealing against hot gas, which comprises a sealing element or a plurality of sealing elements and a carrier device for the sealing element or for the several sealing elements, the sealing system being designed such that at least one state of the sealing element Sealing system with one or at least one sealing element Game is arranged on the carrier device. In embodiments with several sealing elements, it is particularly advantageous if in the

Sealing condition of several, for example all of the several

Sealing elements are arranged with play on the carrier device.

According to the invention, the object is also achieved by a motor vehicle component, in particular a part of an exhaust line, with one

described sealing system solved.

In particular, one advantage of the invention is that the one or at least one sealing element in the sealing state is arranged with play on the carrier device and, as a result, the one or the at least one sealing element has a free space within the play, for example for better adaptation to move to the components to be sealed and to align them accordingly and / or there is a free space within the play to compensate for different thermal expansion behavior of the carrier device and the one or at least one sealing element and at least to reduce, preferably to avoid tension between them.

For example, the arrangement with play of one or the at least one sealing element on the carrier device tensions between them, which could arise due to different stiffnesses of the carrier device and the one or the at least one sealing element, at least reduced, preferably substantially prevented.

For example, one advantage of the invention is that the arrangement of the sealing element with play on the carrier device forces, in particular transverse forces to a sealing axis of the sealing system, between the

Sealing element and the carrier device are at least reduced, preferably substantially avoided. Such forces can occur, for example, when the sealing element is heated by hot gases and expands differently from the carrier device as a result of this heating. The different thermal expansion takes place in particular through the different degrees of heating of the sealing element, which essentially comes into direct contact with the hot gases, and the carrier device, which in particular is not directly exposed to the hot gases. In addition, for example, the thermal expansion of the sealing element and the carrier device is different, since these are formed from materials with different thermal expansion coefficients.

An advantage of the solution according to the invention is in particular that by providing the carrier device, in particular a carrier section thereof, a groove in the components to be sealed can be dispensed with, since positioning of the sealing element and / or the main force circuit and / or compliance with a minimum distance between the components to be sealed is achieved by the provision of the carrier device. In particular, the sealing system can thus be used more flexibly and

for example, the components to be sealed can be manufactured in a structurally simpler manner.

In particular, smaller irregularities between the sealing element and the carrier device can be compensated for by the arrangement with play and / or a different behavior of the same in the sealing state can be compensated for, so that tolerances can be designed to be larger and thus a more cost-effective production of the sealing system is made possible.

In the case of a plurality of sealing elements, it is preferably provided that at least some of them, for example all of them, have the same feature or a plurality of the same features. In particular, one

Arrangement of some of the plurality of sealing elements, in particular an arrangement of all of the plurality of sealing elements, is the same

Characteristic or several identical characteristics. For a simpler description and to avoid repetitions, reference to "the sealing element" is to be understood below as referring to one sealing element or to one sealing element of the several sealing elements, preferably to some of the several sealing elements, for example as all sealing elements . For example, the wording that the sealing element has a feature means that the one sealing element or at least one sealing element of the plurality of sealing elements has this feature and / or that some of the several sealing elements, for example all of the sealing elements, have this feature.

With regard to the arrangement of the sealing element on the carrier device with play, no further details have so far been given.

In a particularly preferred embodiment, it is provided that the sealing system is designed such that, at least in the sealing state, the sealing element and the carrier device are arranged such that they can move with respect to one another. Thus, according to the above explanation, the one or one sealing element, in particular some of the several sealing elements, for example all of the several sealing elements, and the carrier device are preferably arranged such that they can move with respect to one another.

In particular, the sealing element in the sealing state is arranged to be movable relative to a carrier section of the carrier device.

It is preferably provided that the sealing element is arranged on the carrier device such that it can move relative to the carrier device.

In particular, the arrangement of the sealing element and the carrier device which is movable relative to one another ensures that they are not arranged rigidly against one another and thus there is at least a certain mobility between them and thus, for example, the sealing element can be arranged particularly advantageously between the components to be sealed and can adapt to achieve a more reliable seal. In particular, the movable arrangement of the sealing element and the carrier device relative to one another ensures that they can be easily installed during assembly and can be brought into their intended positions, and by the mobility a fine adjustment of the carrier device and the sealing element independently of one another

can be made.

In particular, it is provided that, at least in the sealing state, the sealing element is movably connected to the carrier device. In particular, this achieves the advantages of the movable arrangement and, moreover, the sealing element is roughly positioned in its desired position by the carrier device through the connection of the sealing element to the carrier device. For example, assembly is thereby facilitated since, by connecting the sealing element to the carrier device, these are connected to one another and are therefore easier to assemble.

In particular, the sealing system has a geometric sealing plane. In particular, the sealing system has a sealing axis, which preferably extends at least approximately perpendicular to the geometric sealing plane.

For example, the sealing system extends essentially in the geometric sealing plane. In particular, it is provided that a fluid, for example hot gas, against which the sealing system is to seal, flows at least approximately perpendicular to the sealing plane, for example flows through the sealing system. It is particularly preferred if the sealing system seals in the axial direction of the sealing axis. In other advantageous embodiments, the sealing system seals in the radial direction of the sealing axis. It is particularly advantageous if the sealing system is designed such that, at least in the sealing state, the sealing element on the carrier device is arranged with play in the geometric sealing plane. The arrangement of the sealing element on the carrier device thus has play in the geometric sealing plane. In particular, different expansion behavior of the sealing element and the carrier device, which are induced, for example, by an influence of the hot hot gas, can be compensated for in the geometric sealing plane and / or tensions between the sealing element and the carrier device are caused by the arrangement with play in the geometric sealing plane

at least diminished.

In particular, it is provided that the sealing system is designed such that, at least in the sealing state, the sealing element is arranged with play on the carrier device in at least one direction, in particular in the direction radial to the sealing axis, and is connected to it, for example. Thus, the advantages of the arrangement with play unfold their advantages in this at least one direction.

It is particularly advantageous if the sealing element is arranged captively on the carrier device in an assembled state, in particular is arranged captively with play. For example, the carrier device holds the sealing element captively in the assembled state, for example with play.

In the assembled state, the sealing element and the carrier device are preferably non-positively and / or materially and / or positively connected to one another.

In particular, the sealing system is assembled in the assembled state and brought into the sealed state during assembly. In particular, the assembly state of the sealing system is a state of the same, which it assumes before it assumes the sealing state. In particular, the sealing system is thus arranged in a captive manner on the carrier device before the sealing state, which simplifies the assembly of the sealing system, since the sealing element is arranged in a captive manner on the carrier device and therefore only one unit needs to be brought into an assembly position.

For example, the sealing element is arranged on the carrier device in a correspondingly captive manner even in the sealing state.

It is particularly advantageous if an expansion space is arranged between the sealing element and the carrier device, for example between the sealing element and a carrier section of the carrier device. In particular, the expansion space is arranged as a radial expansion space in the direction radial to the sealing axis between the sealing element and the carrier device. In particular, the

Expansion space for the play of the sealing element

Available and the sealing element has play within the expansion space, for example, to move and / or expand.

In particularly advantageous embodiments, it is provided that the sealing system, in particular the carrier device, has at least one stop. It is preferably provided that the play of the sealing element is given up to the at least one stop. In particular, the sealing element thus has play and in particular a substantially predetermined play up to the at least one stop, and on the other hand, the sealing element is held in the at least rough desired position by the at least one stop in an advantageous manner. In some advantageous embodiments it is provided that the

Sealing system comprises at least one receptacle for an arrangement part. In particular, the sealing element is arranged with play on the carrier device by means of the receptacle and the arrangement part. The arrangement with play is thus achieved in a structurally simple manner in particular. For example, the arrangement of the arrangement part in the receptacle holds the sealing element with play from the carrier device.

It is particularly preferred if the receptacle contains at least part of the

Provides expansion space. In particular, the advantages of the receptacle and the expansion space are thereby combined.

It is preferably provided that, at least in the sealing state, the arrangement part in the receptacle is arranged to be movable relative to the receptacle at least in one direction, preferably in the direction radial to the sealing axis. In particular, the play is provided for the sealing element at least in this one direction.

For example, the sealing element comprises the receptacle and the carrier device comprises the arrangement part.

In particularly preferred embodiments it is provided that the carrier device comprises the at least one receptacle and that the

Sealing element comprises the arrangement part or at least one arrangement part. As a result, the arrangement of the sealing element with play in the receptacle is realized in a structurally simple manner, and play of the arrangement part in the receptacle provides the play for the sealing element.

In some advantageous embodiments it is provided that the

Recording is formed from several recording subspaces. The plurality of receiving subspaces are preferably arranged offset from one another, in particular spatially offset from one another. In particular, the plurality of accommodating subspaces are through one or more accommodating passages connected to each other for reaching through the arrangement part.

In particular, this ensures that the receptacle for the arrangement part in the plurality of receptacle sub-spaces provides free space for the game and, on the other hand, is arranged so as to be captive due to the arrangement of the arrangement part in the plurality of receptacle sub-spaces, which are in particular offset from one another.

It is preferably provided that the receptacle comprises at least one stop, for example the one stop of the carrier device.

In particular, the advantages of providing one are transferred

Stop on the embodiment with at least one recording.

No further details have so far been given about the arrangement of the sealing element and the carrier device.

It is particularly preferred if the sealing element is held by the carrier device. For example, the sealing element is held by the carrier device at least in the axial direction of the sealing axis. In particular, it is achieved that despite the arrangement with play, the sealing element is held by the carrier device and thus they form a unit, for example. In particular, assembly is thereby facilitated, since when the carrier device is positioned, the sealing element held by it is positioned and / or in the sealing state, the sealing element has the game with its advantages, but has also been held by the carrier device at least in a rough desired position becomes.

It is particularly advantageous if the sealing system has a clamp

device includes. The arrangement with play of the sealing element on the carrier device is preferably carried out by means of the clamping device.

In particular, the sealing element is thus arranged on the carrier device by means of the clamping device and, for example, held by the latter, and thus the advantages of the arrangement with play are achieved in this structurally simple implementation. In particular, the clamping device comprises at least one clamping part, which is clamped in particular at least in the sealing state. For example, the clamping part is clamped in the radial direction to the sealing axis. In particularly advantageous embodiments, the clamping part is clamped in a circumferential direction encircling the sealing axis. For example, the clamping part is only clamped in one direction. In other embodiments it is provided that the clamping part is clamped in several directions.

It is preferably provided that the clamping device comprises a clamping section or a plurality of clamping sections. In particular, the one clamping section or the multiple clamping sections are provided for clamping the clamping part. For example, a clamping section jammed the clamping part. In particular, the clamping part is clamped between the plurality of clamping sections. It is particularly advantageous if at least some of the plurality of clamping sections are arranged offset from one another, whereby in particular a particularly favorable one

Pinching of the clamping part is achieved. As an alternative or in addition, it is provided, for example, that at least two clamping sections in the

Are arranged essentially opposite each other and the clamping part is clamped between them, and in particular a particularly simple clamping is realized.

In some embodiments it is provided that the sealing element comprises the one or more clamping sections and the carrier device comprises the at least one clamping part. In particularly preferred embodiments it is provided that the carrier device comprises the one clamping section or at least some, for example all, of the plurality of clamping sections and in particular the sealing element comprises the at least one clamping part. Thus, for example, the clamping part is clamped by the clamping sections and with play and this game is transferred to the arrangement of the

Sealing element, whereby this is arranged with play and captive on the carrier device.

In some advantageous embodiments it is provided that the

Sealing system includes a connecting part. In particular, the connecting part connects the sealing element to the carrier device. It is preferably provided that, at least in the assembled state, the sealing element is arranged on the carrier device by means of the connecting part. In particular, the sealing element is thereby arranged in a captively secure manner on the carrier device and the assembly of the sealing system is simplified.

For example, the connecting part is at least partially elastic

educated. In particular, it is achieved that the sealing element is arranged on the carrier device so that it cannot be lost, and due to the at least partial elasticity of the connecting part, the sealing element is given a play, for example for a different one from the carrier device

Expansion and / or a relative movement to the carrier device is given.

In preferred embodiments, it is provided that the connecting part has at least one predetermined breaking point, that is to say has one predetermined breaking point or several predetermined breaking points. In particular, the at least one predetermined breaking point is designed such that it breaks open in the sealing state, so that in particular the connection between the sealing element and the carrier device is released by the connecting part in the sealing state and the sealing element is therefore arranged with play. No details have so far been given with regard to the design of the sealing element.

Preferably, the sealing element is formed in the circumferential direction around the sealing axis running around closed. In particular, the sealing element thus runs closed around the sealing axis and seals around the sealing axis and a guide section for the fluid, in particular for the hot gas, which runs at least in the area of the sealing element and is essentially coaxial with the sealing axis.

The sealing element preferably comprises a main section, which is provided in particular for sealing. For example, the main section comprises two sealing sections, which are provided in particular for sealing on one side in each case and which seal on the one side in the sealing state. In particular, the two sealing sections each seal on one side of the sealing state

geometric sealing level.

In particular, the two sealing sections are connected to one another by part of the main section. For example, the main section is essentially designed as a Z-ring. In other embodiments, the main section is essentially V-shaped.

It when the two sealing sections in to the

Sealing axis are spaced from each other in the axial direction and, for example, the geometric sealing plane runs between them.

In particular, it is provided that a distance between the two sealing sections, in particular an axial distance in the axial direction from the sealing axis Direction between the two sealing sections, in one

unstressed state, for example in the assembled state, is greater than in the sealed state. Thus, in particular the sealing sections are spaced apart and are preferably in the

Sealed state applied, so that their distance is reduced, and thus a particularly good seal is achieved by the application.

For example, the distance between the two sealing sections, in particular their distance in the axial direction from the sealing axis, in the unloaded state is at least 0.5 mm, preferably at least 1 mm and / or at most 8 mm, for example at most 5 mm. It is particularly preferred if the distance is at least approximately 2 mm.

In some advantageous embodiments it is provided that the carrier device extends in the axial direction of the sealing axis between two geometric carrier end planes. In particular, the carrier device has in each case one carrier support surface on one of the two geometric carrier end planes. The geometric carrier end planes preferably run at least approximately parallel to one another. It is particularly expedient if the geometric support end planes at least

run approximately perpendicular to the seal axis.

In particular, the carrier device thus has a predetermined thickness in the direction between the carrier end planes, in particular in the axial direction to the sealing axis, and in the sealing state serves as a spacer between the components to be sealed. In particular, the

Carrier contact surfaces are particularly cheap to provide a support for the components to be sealed and thus to achieve a stable arrangement with a reliable seal. In particular, takes place in the

Sealing condition, the main power connection via the carrier device and the sealing element is arranged in the force shunt. It is particularly advantageous if at least in the unloaded

State the sealing element is formed with at least one sealing section extending in the axial direction of the sealing axis beyond the carrier device. In particular, at least one sealing section thus projects beyond the carrier device in the unloaded state and thus offers a point of attack for the application. By doing

Sealing condition is provided in particular that the sealing element no longer protrudes beyond the carrier device in the direction axial to the sealing axis. In particular, the sealing sections in the sealing state are essentially arranged in one of the geometrical support end planes, where they form the seal to the components to be sealed.

It is particularly advantageous if in the unloaded state

at least one of the geometric support end planes runs between the two sealing sections and thus in particular at least one of the two sealing sections protrudes beyond the support device and thus provides a point of application for the application.

Preferably, the sealing element is at least partially, in particular fully, made of a metallic material. In particular, the metallic material offers favorable properties with regard to the resistance to the fluid to be sealed, in particular to the hot gases, and is flexible enough to reliably seal.

For example, the metallic material comprises nickel and is preferably a nickel alloy. In some embodiments it is provided that the metallic material comprises spring steel or is spring steel.

For example, the sealing element, at least its main section, is formed from a sheet metal. With regard to the design of the carrier device, no further details have so far been given.

The carrier device is preferably at least partially encompassing the sealing element, the carrier device in particular

Sealing element encompasses at least partially around the circumference of the sealing axis. In particular, the carrier device thus offers a stable hold for the sealing element.

In particular, it is provided that the carrier device comprises a carrier section which at least partially encompasses the sealing element in a favorable manner. For example, the carrier section extends at least partially, preferably completely, around the sealing axis around the sealing element.

In particular, the carrier section is provided as a spacer and / or for a main force connection in the sealing state. A reliable seal is thus achieved in a favorable manner, the main force connection being effected via the carrier device and the sealing element in the force shunt being able to seal reliably and being protected against an excessive, damaging force influence.

In particular, the carrier section extends between the two carrier end planes and has the carrier contact surfaces in these. The carrier section between the carrier contact surfaces is preferably essentially solid. In particular, the carrier section thus forms a stable spacer and the main force connection can take place via this.

In some advantageous embodiments, it is provided that the carrier section of the carrier device is formed in one piece. In particular, it is achieved that this can be produced in a structurally simple manner and is particularly stable due to the one-piece design. In some particularly preferred embodiments it is provided that the carrier device comprises a plurality of carrier layers. It is preferably provided that the carrier section is formed from the plurality of carrier layers. In particular, an inexpensive carrier device can be provided in this way. For example, a carrier device with a complex configuration, for example with a receptacle with a plurality of subspaces, can also be easily produced in a structurally simple manner.

For example, the multiple carrier layers are simply placed on top of one another. It is particularly preferred if the plurality of carrier layers are connected to one another in a cohesive and / or non-positive and / or positive manner. For example, the multiple carrier layers are welded together, in particular spot-welded.

The one or more carrier layers is preferably formed from a metallic material. In particular, an inexpensive metallic material, for example inexpensive steel, can be used, and thus a cost-saving embodiment of the carrier device can be provided.

In particular, one advantage is to be seen in the fact that the carrier device, in particular the one or more carrier layers, can be produced from an inexpensive material, in particular since they are not directly exposed to the hot gases and only for the sealing element which is directly exposed to the hot gases , a higher quality and more expensive material is needed.

Preferably, a thickness of the carrier device in the axial direction to the sealing axis is at least 0.2 mm, preferably at least 0.5 mm and / or at most 3 mm, preferably at most 2 mm. For example, the thickness is at least approximately 0.8 mm. For example, this thickness of the carrier device corresponds to the axial distance between the two carrier end position planes. Above and below, the wording "at least

approximately "to be understood in connection with an indication that deviations that are not technically relevant and or that are due to technical reasons

Deviations from the specification are included. In particular are

Deviations of up to ± 20%, preferably of up to ± 10%, particularly advantageously of up to ± 5%, for example of up to ± 1%, from the given information, for example from a specified value, also included. In the case of specified directions or a specified parallelism, for example, deviations by up to ± 20 °, preferably by up to ± 10 °, in particular by up to ± 5 °, are also included.

according to a third embodiment and Fig. 15 shows a section as shown in Fig. 14 through the carrier device and the sealing element.

A first exemplary embodiment of one designated as a whole by 100

Sealing system comprises a carrier device 112 and at least one sealing element 114. A variant of the exemplary embodiment is shown by way of example in FIGS. 1 to 8.

The sealing system 100 is provided for sealing against a fluid, in particular against hot gases, in particular as a seal transverse to a sealing axis 122.

In particular, the fluid, in particular the hot gases, flows in one

installed state of the sealing system 100 essentially in the axial direction 124 to the sealing axis 122, for example through a fluid guide channel.

The fluid guide channel comprises several parts, for example. In particular, it is provided that the sealing system 100 seals between two parts of the fluid guide channel.

In particular, the fluid flows essentially in the axial direction 124 in a fluid guidance area which runs at least in the area of the sealing system 100 essentially in the axial direction 124.

The fluid guide area also extends in the radial direction 126 to the sealing axis 122 and is in particular at least largely delimited in the radial direction 126 by the parts of the fluid guide channel.

In particular, the sealing system 100 is part of the radial delimitation of the fluid guidance region and extends at least with some parts of the same in a circumferential direction 128 around the sealing axis 122. In particular, the sealing system 100 has a passage opening 132 through which the sealing axis 122 runs. So can

in particular the fluid, in particular the hot gas, essentially pass through the passage opening 132 in the axial direction 124 to the sealing axis 122.

In particular, at least a part of the sealing system 100, for example at least the sealing element 114, borders the passage opening 132. This part, in particular the sealing element 114, runs in the circumferential direction 128 around the passage opening 132, in particular closed, and delimits the passage opening 132 in radial direction 126.

The sealing system 100 is designed, for example, as a flat seal.

In particular, the sealing system 100 extends essentially in a sealing plane 136. The sealing plane 136 runs at least approximately perpendicular to the sealing axis 122.

In particular, extensions of the sealing system 100 are shown in FIG

Sealing plane 136 is substantially larger, for example at least a factor 10 larger, than an expansion of the sealing system 100 in a direction perpendicular to the sealing plane 136.

The sealing element 114 extends in particular in the circumferential direction 128 in a closed manner around the sealing axis 122.

In particular, the sealing element 114 has a main section 152, which likewise extends in the circumferential direction 128 around the sealing axis 122.

In particular, the main section 152 surrounds the passage opening 132, in particular in the sealing plane 136. The main section 152 is provided for sealing, in particular for sealing between the two parts of the fluid guide channel. In the installed sealing state, the main section 152 seals

especially between these two parts. Preferably, main section 152 includes two sealing sections 156 and 158, which

in particular also closed in the direction of circulation 128 around the

Seal axis 122 run around (Fig. 2 and 3).

The two sealing sections 156 and 158 are in particular for

Sealing provided on each side of the sealing system 100.

For this purpose, the two sealing sections 156 and 158 are in the axial

Direction 124 spaced from each other.

In particular, the sealing element 114 is produced from an output element that extends essentially in a surface, in particular in a geometric plane. The sealing element 114 is preferably produced from a sheet metal.

On the two sealing sections 156 and 158, the sealing element 114 is, in particular, curved.

The curvatures on the sealing sections 156 and 158 preferably form suitable sealing surfaces. Due to the bend, in particular on the sealing sections 156 and 158, the main section 152 is preferably resilient and thus adapts favorably to the components to be sealed.

For example, the sealing element 114 is formed in the main section 152 as a Z-ring. The main section 152 has a Z-shaped cross-sectional shape in a radial section. In particular, the main section 152 has a Z-like cross-sectional shape if it comprises two transverse sections which are spaced apart from one another in the axial direction 124 and on one respective edges thereof are connected to one another at a respective connecting part which extends transversely to the axial direction 124. The sealing sections 156 and 158 are formed in particular by the transitions of the respective cross section in the connecting part.

The transverse sections and the connecting part preferably run closed in the circumferential direction 128 around the sealing axis 122.

In variants of the exemplary embodiment, provision is made, for example, for the main section 152 to have a V-like cross-sectional shape. In particular, a V-like main section 152 is formed by two leg sections

formed, which run in particular in the circumferential direction 158 around the sealing axis 122. In particular, the two leg sections each extend transversely to the circumferential direction 128 between two edges. The two leg sections are connected to each other at one of their edges and extend from their connected edges to diverge. In particular, the edges arranged opposite the connected edges form the sealing sections 156 and 158.

In this exemplary embodiment, the carrier device 112 comprises two carrier layers 172 and 174 and in particular is essentially formed from these two carrier layers 172, 174. 4 and 5, the carrier layers 172, 174 are each shown separately by way of example.

The two carrier layers 172 and 174 each extend essentially in a geometrical carrier layer plane 176, 178. In particular, an expansion of the respective carrier layer 172, 174 in their respective carrier layer plane 176, 178 is substantially larger, for example by at least that

10 times, in particular at least 20 times larger, than an extension of the respective carrier layer 172, 174 perpendicular to its corresponding carrier layer plane 176, 178. In an assembled state, the two support layers 172 and 174 are arranged, in particular, one on top of the other and, for example, non-positively and / or positively and / or integrally connected.

In particular, in the assembled state, the two carrier layer planes 176 and 178 run at least approximately parallel to one another and in particular also at least approximately parallel to the sealing plane 136.

For example, the carrier layers 172, 174 are each formed from a sheet metal. The sheet of the support layers 172, 174 is preferably thicker than the sheet which forms the sealing element 114, in particular its main section 152.

In particular, the carrier device 112 has a carrier opening 182 which, in the assembled state, at least partially coincides with the passage opening 132.

In the assembled state, in particular the sealing element 114 and in particular its main section 152 is arranged in the carrier opening 182.

Each of the carrier layers 172, 174 has a respective opening, which together form the carrier opening 182.

In particular, the carrier device 112 has a carrier section 184. In this embodiment, the carrier section 184 is formed by a respective main layer section 186, 188 of the carrier layers 172, 174

educated. The carrier section 184 extends at least partially around the carrier opening 182 and preferably the carrier section 184 extends in the circumferential direction 128 in a closed manner around the carrier opening and thus also around the passage opening 132.

In particular, the carrier section 184 also extends around the sealing element 114, preferably closed in the circumferential direction 128.

The carrier device 112 extends in the axial direction 124 in particular between two geometric carrier end planes 192 and 194. In particular, the carrier end planes 192 and 194 run at least approximately perpendicular to the axial direction 124. In particular, the two carrier end planes 192 and 194 run at least approximately parallel to one another and in particular also at least approximately parallel to the sealing plane 136. In addition, the carrier layer planes 176, 178 in particular also run at least approximately parallel to the carrier end planes 192 and 194.

In particular, the carrier section 184 extends in the axial direction 124 from one carrier end plane 192 to the other carrier end plane 194 and forms a respective carrier contact surface 196, 198 in these carrier end planes 192, 194.

In this exemplary embodiment, a carrier layer 172, 174 thus forms a respective carrier bearing surface 196, 198 and the carrier layers 172, 174 abut one another with respective sides opposite the respective carrier bearing surface 196, 198.

In particular, the carrier section between the carrier contact surfaces 196 and 198 is essentially solid. In a sealing state of the sealing system 100, the sealing element 114 is arranged with play on the carrier device 112, and in particular in this exemplary embodiment it is provided that the sealing element 114 is arranged with play on the carrier device 112 even in an assembled state.

The sealing system 100 in particular comprises at least one receptacle 210.

In this exemplary embodiment, it is provided that the carrier device 112 has a plurality of receptacles 210, for example four receptacles 210, and thus the sealing system 100 also has a plurality of receptacles 210.

Here, the receptacles in this embodiment are essentially the same. The following statements relating to “the receptacle 210” thus relate to each of the plurality of receptacles 210. In variants of the exemplary embodiment, the plurality of receptacles 210 are designed differently. For example, some recordings have only some, the same or different, of the features explained below.

The receptacle 210 is provided for receiving an arrangement part 212. In particular, an arrangement part 212 is provided for each of the plurality of receptacles 210, and so the sealing system 100 preferably comprises an arrangement part 212 for each receptacle 210.

In particular, the arrangement part 212 engages in the receptacle 210.

In this exemplary embodiment, the sealing element 114 comprises the

Arrangement parts 212, for example four arrangement parts 212 for the four receptacles 210. The arrangement part 212 is designed, for example, as a flat section, which in particular extends essentially in the radial direction 126 away from the main section 152.

In particular, the arrangement part 212 comprises an intermediate section 216 and an end section 218. In particular, the arrangement part 212 with the intermediate section 216 is arranged on the main section 152. Of the

The intermediate section 216 extends essentially in the radial direction 126 and merges with the increasing extent of the arrangement part 212 in this direction into the end section 218. In this direction of extension, the arrangement part 212 extends in particular to an im

End portion 218 end of the same.

The arrangement part 212 and the main section 152 are preferably formed in one piece, in particular from the same sheet metal.

In particular, the arrangement part 212 is designed as a tab.

The receptacle 210 has in particular a receptacle space 222 which extends from a receptacle opening 224.

The receiving space 222 preferably comprises a plurality of receiving subspaces 226, which are arranged offset to one another in the axial direction 124 and radial direction 126.

The receiving subspaces 226 are connected to one another by means of a receiving passage 228. For example, the receiving subspaces 226 are partially overlapping, so that in the area of their overlap

Recording subspaces 226 themselves form the receiving passage 228.

The receiving space 222 and in particular the receiving subspaces 226 are delimited by a receiving wall, designated as a whole by 232, which has individual partial wall sections 234. In particular, a plurality of partial wall sections 234 form projections or corners 236 in the receiving space 222. For example, two of these partial wall sections 234 run transversely, in particular at least approximately perpendicularly, to one another and form the projection 236 or the corners 236 in a transition region between these two.

In particular, a receiving passage 228 runs between two projections 236 or corners 236, which connects two receiving subspaces 226 to one another.

In particular, opposed, mutually offset partial wall sections 234 are provided, which in particular extend essentially in the same extension directions.

Thus, in particular, the receiving space 222 is designed as an angled space having a plurality of receiving subspaces 226.

In particular, individual partial wall sections 234 each form a stop 242, a stop 242 in particular being formed by a projection 236 or a corner 236. For example, two stops 242a and 242b are arranged offset from one another in the radial direction 126 and delimit a respective receiving subspace 226 in the axial direction 124. In particular, a receiving passage 228 runs between the respective receiving subspaces 226a and 226b between the stops 242a and 242b.

In addition, the receiving subspaces 226a and 226b delimited by the stops 242a and 242b are preferably offset from one another in the axial direction 124. In particular, the stops 242a and 242b limit their respective receiving subspace 226a and 226b in the opposite direction in the axial direction 124, so that, for example, the stop 242a is arranged below its receiving subspace 226a and the stop 242b above its receiving subspace 226b.

In this exemplary embodiment, the receptacle 210 is formed by the carrier layers 172, 174 of the carrier device 112.

For this purpose, the carrier layers 172, 174 each have cutouts 252, 254, which are arranged, for example, in or adjacent to the respective main layer section 186, 188 in the respective carrier layers 172, 174.

The recesses 252, 254 each have a cavity 262, 264 in the respective carrier layer 172, 174, which is at least partially delimited by a respective edge section 266, 268 of the respective carrier layer 172, 174.

The cavity 262, 264 extends into the respective carrier layer 172, 174 in an extension direction. In particular, the cavities 262, 264 are designed as continuous cavities, ie they extend in the

Direction of extension throughout the respective carrier layer 172, 174, preferably from one side of the respective carrier layer 172, 174 to a side of the carrier layer 172, 174 opposite this side in the direction of extension.

The direction of extension is, in particular, at least approximately parallel to the axial direction 124.

In one of the carrier layers, for example in the carrier layer 172, the cutouts 252 are preferably designed as half-sided cutouts. In particular, a half-sided recess 252 is formed open transversely, in particular at least approximately perpendicularly, to the direction of extension of the cavity 262. In particular, the half-side recess 252 is designed to be open in the radial direction 126. Thus, the edge section 266 limits the cavity 262 transversely, in particular at least approximately perpendicularly, to the direction of extension thereof only partially, the cavity 262 being designed to be open in the non-limited area.

For example, the cavity 262 opens out on the half-sided one

Recess 252 in the carrier opening 182.

In one of the carrier layers, for example in the carrier layer 174, the cutout 252 is designed as a cutout delimited overleaf, with the cutout delimited on the overlap, the cavity 264 being delimited overleaf transversely, in particular at least approximately perpendicularly, to its direction of extension by the edge section 268. Thus, in the case of the recess 254, which is completely delimited on the reverse, the edge section 268 in particular runs around the cavity 264 in a self-contained manner.

A cutout 252 of one support layer 172 preferably corresponds to a cutout 254 of the other support layer 174, the

corresponding recesses 252, 254 form a common receptacle 210.

Recesses 252, 254 corresponding to one another in the different carrier layers 172, 174 are preferably arranged offset with respect to one another, wherein in this exemplary embodiment these recesses 252, 254 are offset with respect to one another in the radial direction 126. Thus, the cavities 262, 264 in the assembled state in the radial direction 126 and axial direction 124 are offset from one another, since the respective support layers 172, 174 are arranged in the axial direction 124 lying one on top of the other. In particular, the cavities 262, 264 each form a receiving partial space 226 and the receiving wall 232 with its partial wall sections 234 is formed by the edge sections 266 and 268 of the recess 252, 254.

In particular, the cutouts 252 and 254 partially overlap, so that their cavities 262, 264 form the receiving passage 228 in an overlap region.

In the assembled state, the arrangement part 212 is received in the receptacle 210, the arrangement part 212 engaging in particular in the receptacle 210.

In particular, the arrangement part 212 extends through a plurality of receiving part spaces 226.

For example, the intermediate section 216 extends through the receiving partial space 226 formed by the half-side recess 252, preferably from the area opened transversely to the direction of extension of the cavity 262 to an area of the cavity 262 which forms the receiving passage 228. In this case, the intermediate section 216 preferably lies against the stop 242a, which is formed by an edge section 268 of the other carrier layer 174.

In a transition area between the intermediate section 216 and the end section 218, the arrangement part 212 is preferably partially curved and runs with this curved transition area through the receiving passage 228. The end section 218 of the arrangement part 212 is arranged in particular in the receiving part space 226 formed by the recess 254 delimited on the rear. The end section 218 preferably lies on the stop 242b, which passes through an edge section 266 of the other carrier layer 172

is being trained.

The receptacle 210, in particular its receptacle space 222, has a greater extent than the arrangement part 212, so that the

Arrangement part 212 is recorded with play in the receptacle 210.

In particular, an expansion of the receiving space 222 is radial

Direction 126 is greater than an expansion in the radial direction 126 of the area of the arrangement part 212 accommodated in the receptacle 210, so that the arrangement part 212 can still expand or move in the radial direction 126 with play into a free space in the accommodation space 222.

In particular, the end section 218 is made shorter in the radial direction 126 than an expansion of the receiving subspace 226 receiving it.

In particular, in a variant of the exemplary embodiment it is provided that the arrangement part 212 is clamped between the two stops 242a and 242b, so that this variant of the exemplary embodiment comprises a clamping device, designated overall by 310.

The arrangement part 212 is a clamping part 312 between the clamp

sections 314 pinched.

The clamping sections 314 are formed by parts of the edge sections 286, in particular by the stops 242a, 242b. In particular, the clamping part 312 is clamped between the stops 242a and 242b oriented opposite to the axial direction 124 and thus essentially clamped in the axial direction 124.

For further details of a preferred embodiment of the clamping part 312 formed by the arrangement part 212 and the clamping sections 314 formed by the edge sections 266, 268, reference is made to FIG

Versions in connection with the arrangement part 212 and the edge sections 266, 268 and in particular with respect to the further versions in connection with the receptacle 210, in particular with the receptacle wall 232 and the stops 242.

In summary, the functioning of the sealing system 100 is essentially as follows:

The carrier device 112 holds the sealing element 114 with play. In particular, the sealing element 114 is arranged in the carrier opening 182 and the sealing element 114 surrounds the passage opening 132.

In particular, the carrier device 112, in particular with the carrier section 184, essentially encompasses the sealing element 114, with a clearance running between the two, so that the sealing element 114 still has space for expansion, in particular a thermally induced expansion, and / or an escape space for the sealing element 114 for positions

shifts of the same is present.

In particular, a radial extension of the sealing element 114, in particular with the exception of the regions of the arrangement parts 212, is essentially smaller than a radial extension of the carrier opening 182, so that at least in the radial direction 126 essentially between the sealing element 114 and the carrier device 112, in particular theirs Carrier section 184, a free space, which is designed in particular as a gap, runs. For easier assembly and as a protection against loss, the sealing element 114 with the arrangement part 212, which engages in the receptacle 210 of the carrier device 112, is arranged on the same.

For sealing between two components to be sealed, the sealing system 100 with the carrier device 112 and the sealing element 114 is positioned between the two components to be sealed and subjected to force, whereby in particular the components and the parts of the sealing system 100 are pressed against one another.

The main force connection between the components to be sealed takes place via the carrier section 184. This is designed for this purpose and is designed to be correspondingly stable.

The sealing element 114 lies between the two components to be sealed in the force shunt, one of the sealing sections 156, 158 in each case sealingly abutting one of the two components to be sealed.

For this purpose, in particular the main section 152 is deformed and, for example, the sealing section 158 projecting in the axial direction 124 beyond the carrier end plane 194 is pressed in the region between the two carrier end planes 194, 192, and in particular the other sealing section 156 is also pressed sealingly against the other component to be sealed.

Although the sealing element 114 is held by the carrier device 112, a relative position thereof relative to the carrier device 112 can still be changed by the arrangement with play, so that the assembly of the sealing system 100 is simplified. In addition, tolerances for the components can be made larger. In the installed sealing state, in particular hot gas flows through the passage opening 132, as a result of which the sealing element 114 in particular is heated or even heated and thereby expands thermally induced.

Since the sealing element 114 is arranged in a space surrounding it and is held by the carrier device 112 with play, the sealing element 114 has a free space for the thermally induced expansion, so that this takes place without essentially creating tension in the sealing element 114.

Another variant of the exemplary embodiment, in particular as a seal in the exhaust line of a motor vehicle, for example as an exhaust gas turbocharger seal, is shown by way of example in FIG. 9.

Again, this sealing system 100 comprises a carrier device 112, which holds a sealing element 114 with play.

For example, the carrier device 112 in turn comprises carrier layers 172, 174 and has a carrier opening 182 in which the

Sealing element 114 is arranged.

In addition, the carrier device 112 comprises a carrier section 184 which, in particular in a circumferential direction 128 and in the radial direction 126, extends closed around the sealing element.

The carrier device 112 also has receptacles 210 for receiving arrangement parts 212, as a result of which the sealing element 114 is held on the carrier device 112 with play. Furthermore, it is particularly provided that the carrier device 112

Has attachment points 322. In particular, the fastening points 322 are provided in order to fasten the carrier device 114 to at least one of the components to be sealed.

In particular, openings are arranged at the fastening points, in particular in the support layers 172, 174. In an assembled state, fastening means, in particular screws, reach through these openings and thus achieve the fastening and, for example, an additional application.

In a further variant of the exemplary embodiment, which is shown by way of example in FIG. 10, the sealing system 100 comprises a plurality of sealing elements 114.

In particular, this variant is also provided for sealing in an exhaust line of a motor vehicle, for example as an exhaust manifold seal.

Each of the sealing elements 114 extends around a respective passage opening 132.

In particular, it is provided that the carrier device 112 for each

Sealing element with associated sealing opening 132 has a corresponding carrier opening 182, in which these are arranged.

In particular, it is provided that the carrier section 184 extends at least with partial sections around each of the carrier openings 182. A respective partial section is preferably designed to run around the respective carrier opening in a closed manner. For example, it is provided that the carrier section 184 is formed to extend flat between two carrier openings.

For example, provision is made for at least some of the sealing elements 114, in particular their respective main section 152, to have an essentially oval shape or essentially a polygonal shape, for example a rectangle, with rounded corners in an axial plan view. In this case, the main section 152 in particular essentially runs along a contour which is oval or corresponds to a polygon with rounded corners.

The stress on the sealing elements, in particular due to the thermally induced expansion, is different in different sections of the main section 152 because of the different curvature in these sections. Relief for the sealing element is ensured by its arrangement with play.

It is also preferably provided that the design of the sealing element 114, in particular its main section 252, is designed in accordance with the different loads. For example, a material thickness or an axial spacing of the sealing sections 156, 158 along the extent of the main section 152 is designed differently.

Otherwise, all other features and elements in these variants are at least essentially the same as in the first

Variant of the exemplary embodiment described with its variations, so that with regard to the description thereof, reference is made in full to the above explanations. In a second exemplary embodiment, which is shown by way of example in FIGS. 11 to 13, those elements which are at least in the

Are essentially the same or their function is at least fundamentally the same as for the corresponding elements of the first

Embodiment, with the same reference numerals as the corresponding elements in the first embodiment and regarding the description thereof, reference is made to the explanations in connection with the first embodiment, unless otherwise stated. For example, if a variation of an element or feature in this exemplary embodiment should be particularly pointed out in comparison to the first exemplary embodiment, is indicated

in particular provide the corresponding reference symbol with a dash.

A carrier device 112 is also in this exemplary embodiment

provided, a sealing element 114 being arranged in a carrier opening 182 thereof.

The sealing system 100 has a clamping device 310, by means of which the sealing element 114 is arranged on the carrier device 112.

In particular, a clamping part 312 is clamped between two clamping sections 314a and 314b.

The clamping part 312 comprises an expansion element 332, which is arranged between the two clamping sections 314a and 314b. In particular, the two clamping sections 314a and 314b are opposite one another

arranged.

The expansion element 332 has an extension in an extension direction which is greater than a distance between the two clamping sections 314a and 314b. In the assembled state, the expansion element 332 is inserted between the two clamping sections 314a and 314b, specifically in such a way that its direction of extension extends essentially from one of the clamping sections 314 to the other clamping section 114. Due to the extension of the expansion element 332 in this direction, which is greater than the distance between the two clamping sections 314 from each other, the spreading element 332 is thus clamped between the clamping sections 314.

Furthermore, the clamping part 312 in particular comprises a holding section 334, which holds the expansion element 332 on the main section 152.

Preferably, the clamping part 312 is T-shaped, the holding portion 334 widening in the transition to the expansion element 332.

For example, the clamping sections 314 are formed by edge sections 266 'of a recess 252' in the carrier layer 272.

In particular, the cutout 252 has a cutout opening 342 which the cutout 252 ′ to the carrier opening 182 and thus to

Sealing element 114 opens.

It is preferably provided that a cavity 262 ′ of the cutout 252 ′, starting from the cutout opening 342, widens as it extends into the carrier layer 172, in particular stepwise

broadened.

An edge section 266 'thus forms a stop 242' directed inward into the recess 252 'at the widening of the cavity.

In particular, the carrier device 112, in particular the carrier layer 172, also has a receptacle 210 for the clamping part 312, which thus also forms an arrangement part 212. The clamping part 312 forming the arrangement part 212 engages with its holding section 334 through the cutout opening 342 into the cutout 252 '.

In particular, the expansion element 332 extends in the widened region of the cavity 262 '. When the clamping part 312 moves out of the recess 252 ', this play has up to the stop 242' and when the clamping part 312 moves beyond this play, and in particular when the entire sealing element 114 moves beyond the play, the clamping part strikes 312, in particular with the expansion element 332, against the stop 242 ', so that the clamping part 312 does not slip out of the recess 252'.

It is preferably provided in this exemplary embodiment that only one carrier layer 172 forms the carrier section 184 and in particular the carrier device 112 comprises only one carrier layer 172.

The one carrier layer 172 extends between the two carrier end planes 192 and 194 and forms a respective carrier contact surface 196, 198 in these carrier end planes 192, 194.

In this case, the one carrier layer 172 forms one of the carrier support surfaces 196, 198 on opposite sides thereof.

In addition, all other features and elements in this exemplary embodiment are preferably at least substantially the same as in the first exemplary embodiment and / or its variants, so that with regard to the description thereof, reference is made in full to the explanations in connection with the first exemplary embodiment. In a third exemplary embodiment, which is shown by way of example in FIGS. 14 and 15, those elements which are at least in the

Are essentially the same or have at least basically the same function as corresponding elements in the first or second exemplary embodiment, with the same reference numerals as the corresponding element and with regard to the description thereof, reference is made to the explanations in connection with the first and / or second

Embodiment referenced, unless otherwise stated below.

In the third exemplary embodiment as well, the sealing system 100 comprises a carrier device 112 on which a sealing element 114 is arranged.

The carrier device 112 has a carrier opening 182, in which a main section 152 of the sealing element 114, which comprises two sealing sections 156, 158, is arranged.

In particular, the carrier device 112 comprises a carrier layer 172, which forms a carrier section 184.

In particular, the carrier layer 172, in particular at least in the region of the carrier section 184, extends between two carrier end planes 192, 194.

The carrier layer 172 has a carrier contact surface 196, which extends in particular in one of the carrier end planes, for example in the carrier end plane 192.

In particular, the carrier section 184 has the carrier contact surface 196. The sealing element 114 is arranged by means of a connecting part 352 to the carrier device 112. In this exemplary embodiment it is provided that the connecting part 352 is formed in one piece with the sealing element 114 and in particular its main section 152. In variants, the connecting part 352 is arranged on the sealing element 114 and these are preferably connected to one another in a material and / or non-positive and / or positive manner.

In particular, the sealing element 114 comprising the main section 152 and the connecting part 352 is formed from a sheet metal.

For example, the connecting part 352 is essentially flat and in particular rests on the carrier support surface 196.

The connecting part 352 has a plurality of predetermined breaking points 354.

The predetermined breaking points 354 are arranged in a separation area 356 of the connecting part 352. The separating region runs, in particular in a ring shape, around the main section 152, and in particular around the passage opening 132, in the circumferential direction 128 in a closed manner.

The separating region 356 preferably runs along an edge of the carrier layer 172, in particular of the carrier section 184, this edge delimiting the carrier opening 182. The separation region 356 thus thus runs, for example, in a transition from the carrier opening 182 to the carrier section 184.

In the separating area 356, the connecting part 352 is essentially formed by breaks and two sections of the connecting part 352 running on a respective side of the separating area 356 are only connected to one another by a plurality of webs 362. Zones 364 free of material run between the individual webs 362 in the direction of circulation 128.

The material-free zones 364 thus run in particular along the edge of the carrier layer 172, the main section 152 arranged in the carrier opening 182 being connected only by the individual webs 362 to a section of the connecting part 352 lying on the carrier bearing surface 196 and connected to the carrier layer 172.

When the sealing system 100 is installed, the carrier device 112 with the sealing element 114 is positioned between the two components to be sealed and these are subjected to force.

As a result of the action, which also acts on the connecting part 352 with the predetermined breaking points 354, the connecting part 352 breaks at the predetermined breaking points 354. In this case, the webs 362 in particular break.

The arrangement of the predetermined breaking points 354, that is to say in particular also the arrangement of the separation area 356, on the edge of the carrier layer 172 is particularly favorable since the application of the predetermined breaking points 354 to the edge supports the breaking thereof.

Thus, in the installed and sealing state, the main section 152 with the sealing sections 156 and 158 is detached from the carrier device 112, in particular from the carrier layer 172, and can move and / or expand substantially freely in the carrier opening 182 at least in the radial direction 126, for example, expand due to the heating by the hot gases against which the sealing system 100 seals.

Thus, the sealing element 114 with its main section 152 is in the

Sealed state in the carrier opening 182 held with play. The main section 152 has play to move easily and for expansion, in particular a thermally induced expansion. In addition, the further features and elements in this exemplary embodiment are preferably configured essentially as in the first and / or second exemplary embodiment or their variants, so that with regard to the description thereof, reference is made to the statements in connection with the first and second exemplary embodiments.
