Abstract

In order to improve an assembly, in particular for vehicle construction, comprising at least two components and at least one sealing element which seals in a sealing region between the at least two components, it is proposed that the sealing element comprises a one-piece sealing body and that the sealing body forms a main seal between the at least two components in the sealing region and a secondary seal spatially offset from the main seal between the at least two components.

Description

The invention relates to an assembly with a sealing element and a use of a sealing element for an assembly. The invention also relates to a vehicle component and a vehicle, each with components between which a sealing element seals.

The object underlying the invention is to improve an assembly with a sealing element and a use of a sealing element for an assembly and a vehicle component and a vehicle.

In embodiments of the invention, the above-mentioned object is achieved by an assembly which comprises at least two components and at least one sealing element which seals in a sealing region between the at least two components, wherein the sealing element comprises a one-piece sealing body and the sealing body forms a main seal between the at least two components in the sealing region and a secondary seal spatially offset from the main seal between the at least two components.

In embodiments of the invention, the above-mentioned object is achieved by using a sealing element comprising a one-piece sealing body for an assembly comprising at least two components for sealing between the at least two components in a sealing region, wherein in the sealing region the sealing body forms a main seal between the at least two components and a secondary seal spatially offset from the main seal between the at least two components.

In particular, an advantage of the solutions according to the invention is that the secondary seal provides increased protection against unwanted and damaging media and that the one-piece design of the sealing body, which forms both the main seal and the secondary seal, enables the main seal and secondary seal to be implemented in a smaller installation space.

Advantageously, a sealing effect is increased by the sealing element with the one-piece sealing body, since media against which sealing is required must overcome both the main seal and the secondary seal and a distance to be overcome is increased.

Media against which sealing is carried out and which are particularly undesirable and/or damaging are in particular aggressive media and/or, for example, dirt particles and/or in particular liquids.

For example, at least some aggressive media are liquid and/or gaseous and/or solid.

In particular, aggressive media are those media which attack the material of at least one component of the assembly, for example the material of at least one of the two components between which sealing is to be carried out and/or is carried out.

In particular, an aggressive medium chemically attacks the material.

In particular, a corrosion-promoting medium, for example a corrosion-promoting liquid, is an aggressive medium.

For example, a medium containing electrolytes is an aggressive medium.

In particular, a saline medium, for example a saline liquid, is an aggressive medium.

In particular, the harmful influence of an aggressive medium in particular can cause the material of a component in the area of the secondary seal or main seal to be at least partially damaged and as a result the tightness in the area of this seal to suffer or decrease.

In particular, an advantage of some embodiments according to the invention is that if the sealing effect of the main seal or secondary seal decreases, for example due to damage, the secondary seal or main seal is still present and the overall seal through both seals still has a reliable sealing effect.

In particular, in some embodiments of the invention, the sealing element has a longer service life with a reliable sealing effect.

For example, one advantage of the solutions according to the invention is that they can be implemented more cost-effectively, since the one-piece sealing body forms both the main seal and the secondary seal.

It is particularly advantageous that, for example, assembly is simplified, since only the one-piece sealing body needs to be installed for the main seal and the secondary seal.

For example, the solution according to the invention offers the advantage that the sealing element with the one-piece sealing body, which forms the main seal and the secondary seal, can be installed, for example, between known components, whereby only minor adjustments at most have to be made to the sealing sections of the components.

In particular, the sealing element with the one-piece sealing body can be integrated into the existing installation space in existing designs of two components between which sealing is to be carried out.

No further details have been provided to date regarding advantageous designs of the sealing element, in particular the main seal and the secondary seal.

It is particularly advantageous if the secondary seal is at least partially sealed at a sealing level whose position with respect to a sealing direction of the seal is different from a position of a sealing level in the main seal.

For example, a position of a sealing level of the main seal and/or the secondary seal related to the sealing direction is defined by the position of the part of the sealing body which forms the main seal or the secondary seal. In particular, a position along the sealing direction at which a seal is formed between the sealing body, in particular a sealing side of the sealing body, and a sealing section of one of the at least two components, in particular a sealing surface of this sealing section, defines the position of a sealing level.

In particular, the sealing body seals in the sealing direction between the sealing sections on the at least two components, so that in the sealing body, a passage of a medium against which sealing is being carried out is advantageously at least substantially blocked transversely to the seal.

Advantageously, the at least one secondary seal is arranged offset from the main seal at least transversely to the sealing direction.

Advantageously, the sealing level of the secondary seal and the sealing level of the main seal, which have a different position along the sealing direction, are sealing levels between the sealing body and an identical one of the at least two components.

In particular, an advantage of the different positions of the sealing levels in the secondary seal and the main seal is that a distance to be penetrated by a medium against which sealing is being carried out is extended and, in particular, is made more complex, since in particular the medium not only has to penetrate the seal transversely to the sealing direction, but also has to at least partially penetrate a distance in the sealing direction, thereby increasing the sealing effect of the seal.

Advantageously, a more compact design can be achieved by sealing the secondary seal and the main seal at different sealing levels. For example, the different sealing levels of the secondary seal and the main seal mean that both the main seal and the secondary seal can be installed in an existing installation space, for example, because the installation space required for this is less wide transversely to the sealing direction than, for example, with a multiple-sealing seal at one sealing level.

In particular, each of the at least two components has at least one main sealing surface for the main seal and at least one secondary sealing surface for the secondary seal.

Preferably, the sealing body forms at least one main sealing line on at least one main sealing surface in the region of the main seal on the at least two components.

In some advantageous embodiments, exactly one main sealing line is provided on the corresponding main sealing surface.

In preferred embodiments, the sealing body forms several main sealing lines on at least one, preferably on a respective, main sealing surface.

Preferably, it is provided that in the region of the secondary seal, the sealing body forms at least one secondary sealing line on at least two components, each on at least one secondary sealing surface.

In some advantageous embodiments, it is provided that a distance in the sealing direction between the at least one main sealing line on one of the at least two components and the at least one main sealing line and the other of the at least two components is greater than a distance in the sealing direction between the at least one secondary sealing line on one of the at least two components and the at least one secondary sealing line on the other of the at least two components.

Advantageously, on at least one component of the at least two components, the at least one main sealing line and the at least one secondary sealing line are formed at different position levels with respect to the sealing direction.

Advantageously, such a medium against which sealing is carried out must, in addition to the sealing, also overcome the position difference between the at least one main sealing line and the at least one secondary sealing line.

In some advantageous embodiments, the different position of the at least one main sealing line and the at least one secondary sealing line is advantageous in order to accommodate the main seal and the secondary seal compactly in a small installation space.

Preferably, it is provided that the sealing body is advantageously pressed between the at least two components in the sealing direction at least partially, in particular at least in the region of the main seal and/or in the region of the secondary seal.

Advantageously, the sealing body has several sealing sides.

In particular, at least a part of a respective sealing side in an installed and sealing state lies sealingly against a respective sealing surface of one of the at least two components.

Advantageously, two sealing sides of the sealing body, for example two sealing sides for the main seal and/or two sealing sides for the secondary seal, are opposite each other in the sealing direction.

In advantageous embodiments, a sealing side, for example a sealing side for the secondary seal, is retracted in the sealing direction relative to another sealing side of the sealing body, which is oriented in the same direction and/or which, in an installed and sealed state, at least partially seals against the same component.

For example, one end face of the sealing body relative to the sealing direction forms the further sealing side and one sealing side is retracted relative to the end face in the sealing direction.

In some advantageous embodiments, a sealing side for the main seal and a sealing side for the secondary seal of the sealing body are formed by an end face of the sealing body relative to the sealing direction.

In favorable embodiments, it is provided that the sealing body in the area of the main seal has a larger extension in the sealing direction than in the area of the secondary seal.

In particular, the expansion in the sealing direction between two respective opposite sealing sides of the sealing body is measured.

For example, the sealing body comprises a main sealing bead for forming the main seal and/or a secondary sealing bead for forming the secondary seal.

In particular, the main sealing bead is larger than the secondary sealing bead, at least in the sealing direction.

In particular, the secondary sealing bead is formed directly or indirectly onto the main sealing bead.

In some advantageous embodiments, the sealing body has at least one engagement recess.

In particular, the at least one engagement recess of the sealing body is designed for an engagement of an engaging segment of one of the two components. The engaging segment advantageously engages in the at least one engagement recess of the sealing body in the assembled and sealing state.

In particular, the main seal or the secondary seal is formed in the region of the at least one engagement recess.

Advantageously, the at least one engagement recess and the segment engaging therein at least co-form the main seal or the secondary seal.

Advantageously, a sealing side of the sealing body, in particular a sealing side for the main seal or a sealing side for the secondary seal, is formed in the at least one engagement recess.

In particular, the part of the sealing body with the at least one engagement recess is formed directly or indirectly onto another part of the sealing body, which at least co-forms the secondary seal or the main seal. For example, the part of the sealing body with the at least one engagement recess is formed onto the secondary sealing bead or the main sealing bead is formed directly or indirectly.

For example, in favorable embodiments, the part of the sealing body with the at least one engagement recess is formed via a connecting part with another part of the one-piece sealing body, for example to the secondary sealing bead or the main sealing bead.

For example, in favorable embodiments, the secondary sealing bead is formed onto the main sealing bead via a connecting part of the one-piece sealing body.

For example, the connecting part has a smaller expansion in the sealing direction than the secondary sealing bead.

In some advantageous embodiments, the connecting part is arranged between the at least two components, but the connecting part is not pressed between the at least two components.

In advantageous embodiments, the sealing body has at least one sealing lip, in particular for the main seal and/or for the secondary seal.

In particular, at least one sealing lip is formed on at least one sealing side. Preferably, at least one sealing lip is formed on at least some sealing sides and/or, for example, on all sealing sides.

For example, at least one sealing lip is a protruding formation on the sealing side in the sealing direction.

For example, the at least one sealing lip for the main seal is formed from the main sealing bead. For example, the at least one sealing lip for the secondary seal is formed from the secondary sealing bead.

Conveniently, at least one sealing lip or each of the plurality of sealing lips forms a respective sealing line with a respective sealing surface of a component against which the respective sealing lip rests, in particular is pressed.

In an advantageous embodiment, it is provided that the sealing body is at least partially, i.e. in particular only partially or preferably completely, formed from a soft sealing material.

For example, the soft sealing material comprises at least one elastomer.

In particular, it is provided that the at least two components each have at least one sealing surface, in particular at least one sealing surface for the main seal and/or at least one sealing surface for the secondary seal.

Advantageously, the sealing body rests at least partially on a respective sealing surface in the installed and sealing state.

In particular, at least one sealing line is formed on each sealing surface.

In advantageous embodiments, it is provided that in at least one component of the at least two components, two sealing surfaces, in particular a sealing surface for the main seal and a sealing surface for the secondary seal, are formed at different position levels related to the sealing direction.

Ideally, such a medium against which sealing is to be carried out must, in addition to the sealing, also overcome the positional difference between the at least two sealing surfaces.

For example, the different position of the at least two sealing surfaces in the sealing direction can make the sealing area more compact and require less installation space.

In some favorable embodiments, at least one component of the at least two components has at least one segment on which at least one sealing surface is formed, wherein this segment protrudes in the sealing direction beyond at least one other sealing surface of this component, in particular protrudes in the direction of the other of the at least two components.

For example, the at least one sealing surface is formed on an end face of the protruding segment facing the other component.

For example, the projecting segment is a protruding segment and/or a wall segment.

In some advantageous embodiments, at least one component of the at least two components in the sealing region has at least one recess formed in the sealing direction.

In particular, the recess has exactly one recess or exactly one recess of several recesses or at least some of several recesses have at least one of the features explained below. For example, some of several depressions have at least one different feature.

For example, a medium against which sealing is to be carried out must also overcome the recess so that protection against this medium is improved.

In some advantageous embodiments, the sealing body is at least partially arranged in a recess in the installed and sealing state.

In particular, the sealing body can be arranged in a precise position and, for example, it is held in one position by the recess.

Advantageously, at least one sealing surface of a component is formed in at least one recess of this component, for example on a recess bottom of the recess.

Advantageously, at least one sealing surface can be formed in this way in a space-saving manner.

In particularly advantageous embodiments, it is provided that a sealing surface of this component is formed on a segment delimiting a recess, for example a protruding segment and/or a wall segment.

In particular, this makes it possible to realize a solution that saves installation space and/or improves protection against unwanted media.

In some advantageous embodiments, at least one recess of at least one component is formed transversely to the sealing direction between the main seal and the secondary seal.

In particular, at least one recess of at least one component is formed transversely to the sealing direction between the secondary sealing surface and the main sealing surface of this component.

Advantageously, the at least one recess between the main seal and the secondary seal acts as an additional barrier for a medium against which sealing is to be and/or will be carried out.

In particular, the passage of a medium through the sealing area, in particular the flow of a liquid medium, is at least made more difficult by the at least one recess between the main seal and the secondary seal.

For example, a medium, in particular a liquid medium, is at least partially held back in the at least one recess between the main seal and the secondary seal, in particular by the action of adhesion forces and/or cohesion forces and/or the surface tension of the medium. For example, the medium collects at least partially in the recess.

In particular, the space in the at least one recess between the main seal and the secondary seal is free and, advantageously, the sealing body does not engage in this recess.
In some advantageous embodiments, it is provided that in at least one component of the at least two components, at least two sealing surfaces of this component are formed at the same position level with respect to the sealing direction.

For example, in embodiments with multiple secondary seals, the sealing surfaces of at least two secondary seals in this component are at the same position level.

In some advantageous embodiments, a sealing surface for the main seal and a sealing surface for the secondary seal are formed on the same position level with respect to the sealing direction in at least one component, in particular in only one component of the at least two components.

For example, this enables a space-saving and/or structurally less complex design to be realized.

For example, two sealing surfaces formed at the same position level are formed on different segments of one component.

In some advantageous embodiments, two sealing surfaces formed at the same position level are formed by an identical surface segment of this component.

In preferred embodiments, it is provided that the sealing body is arranged in the secondary force connection between the at least two components.

In particular, the main frictional connection between the at least two components occurs directly or indirectly between them, but not via the sealing body.

In some advantageous embodiments, the two of the at least two components each have a frictional connection surface via which the main frictional connection between the components takes place, in particular directly and/or indirectly.

In some advantageous embodiments, fastening points on the at least two components and/or fastening means with which the at least two components are fastened to one another are designed in such a way that the main force connection takes place at them and/or excessive pressing of the sealing body is prevented.

In particular, the sealing area extends at least in sections in a longitudinal direction. In particular, the longitudinal direction is oriented in the same direction in individual sections and in a different direction in different sections, for example in order to form a circumferentially self-contained sealing area.

In particular, the sealing lines run in the longitudinal direction.

In particular, the at least two components in the sealing region are arranged opposite one another in a vertical direction, wherein in particular the vertical direction runs at least approximately perpendicular to the longitudinal direction.

In particular, a transverse direction in the sealing region runs at least approximately perpendicular to the longitudinal direction and at least approximately perpendicular to the vertical direction.

Advantageously, two spatial areas located opposite one another in the transverse direction are at least substantially separated from one another by the seal in the sealing area, at least for the media against which the seal is made.

In particular, a gap runs between the at least two components, in particular between their sealing sections. In particular, this gap connects the two spatial areas located on either side of the at least two components in a pre-assembled state. Advantageously, the sealing of the sealing body at least substantially prevents the passage of media against which sealing is being carried out through the gap in the sealed state.

Advantageously, the sealing body extends at least partially elongated in an extension direction, wherein the elongated extension of the sealing body in the extension direction is formed at least substantially corresponding to the elongated course of the sealing region in the longitudinal direction.

In particular, the sealing body has a thickness measured in a thickness direction and a width measured in a width direction, wherein the thickness direction and the width direction run at least approximately perpendicular to each other and both the thickness direction and the width direction each run at least approximately perpendicular to the extension direction.

Preferably, the sealing body has a thickness that varies along its extension in the width direction.

For example, the sealing body has a width that varies in the thickness direction.

In particular, the sealing body is arranged in the sealing region such that its thickness direction is oriented at least approximately parallel to the vertical direction and/or its width direction is oriented at least approximately parallel to the transverse direction.

In some advantageous embodiments, the sealing direction is oriented at least approximately parallel to the vertical direction and/or the thickness direction.

In some preferred embodiments, the sealing direction is oriented at least approximately parallel to the transverse direction and/or the width direction.

In some advantageous embodiments, the components of the assembly define an interior space. In particular, the interior space is separated from the environment of the assembly by the at least two components of the assembly.

In some advantageous embodiments, at least one secondary seal in the sealing area is arranged closer to the environment of the assembly than the main seal.

In particular, the secondary seal forms a first barrier for a medium coming from the environment. This first barrier advantageously increases the sealing effect of the entire seal. For example, parts that are located behind the secondary seal in relation to the direction transverse to the sealing direction, for example parts of the main seal, are already somewhat protected by the secondary seal, so that the service life of the seal is increased.

In some preferred embodiments, at least one secondary seal in the sealing region is arranged closer to the interior than the primary seal.

In particular, the secondary seal forms an additional barrier and an additional Protection is provided if at least residual parts of an undesirable medium from the environment overcome the main seal, whereby these penetrating medium parts would then still have to overcome the secondary seal, and thus the interior is better protected.

In some advantageous embodiments, the gap between the at least two components between the sealing element and the environment of the assemblies has no dead space.

In some particularly advantageous embodiments, the sealing element, in particular its sealing body, extends in the gap between the at least two components at least on one side to one end of the gap, wherein in particular at the end of the gap the gap merges into one of the two spatial regions located on both sides. In particular, the sealing element, in particular its sealing body, extends to one end of the gap, at which the gap merges into an area surrounding the assembly.

In particular, the sealing element, in particular its sealing body, extends transversely, for example at least approximately perpendicularly, to the sealing direction to at least one end of the gap.

In some preferred embodiments, the sealing element, in particular its sealing body, is flush on at least one side of the assembly which faces one of the two spatial regions located on both sides, advantageously on the side which faces the surroundings of the assembly, with at least one, i.e. exactly one or both, of the at least two components between which sealing is to be carried out and/or is carried out.

Advantageously, an accumulation of a medium against which sealing is to be carried out and/or which is undesirable and/or damaging is at least reduced or even advantageously at least substantially completely prevented.

The components of the assembly can be made of a wide variety of materials.

In some preferred embodiments, a material of at least one component of the assembly, in particular a material of at least one component of the at least two components between which sealing is to be and/or will take place, comprises and/or is a metal.

For example, one advantage of this is that the at least one metallic component enables and/or improves electromagnetic compatibility (EMC) of the assembly and, in particular, electromagnetic interference can at least be reduced.

In such embodiments, the sealing body forming a main seal and a secondary seal is particularly advantageous because at least one metallic component is protected particularly favorably by the seals formed and/or even in the event of partial damage to the at least one metallic component, for example due to corrosion, an at least substantially reliable sealing effect is still achieved due to the spatially offset arrangement of the main seal and the secondary seal.

In some preferred embodiments, a material of at least one component of the assembly, in particular a material of at least one component of the at least two components between which sealing is to be and/or will take place, comprises and/or is a plastic.

For example, this is advantageous because the plastic component is at least less susceptible or not at all susceptible to corrosion.

The sealing element can be used in a wide variety of applications.

The use of the sealing element is particularly advantageous in vehicle construction, in particular in motor vehicle construction, for example in automobile construction, and/or in rail vehicle construction and/or in shipbuilding, for example for ferries, and/or in aircraft construction.

The assembly can be an assembly for a wide variety of applications.

In particular, the assembly is an assembly for vehicle construction, advantageously for motor vehicle construction, for example automobile construction, and/or shipbuilding, for example for ferries, and/or rail vehicle construction and/or aircraft construction.

For example, the components of the assembly form a housing, wherein the housing defines an interior space. The interior space is advantageously sealed by the at least one main seal formed by the sealing body and the at least one secondary seal.

In particularly advantageous embodiments, the sealing element comprising the sealing body and in particular the assembly comprising the sealing element and at least two components is used for a vehicle component, in particular for a Motor vehicle component, for example an automobile component, and/or for a ship component, for example a component of a ferry, and/or for a rail vehicle component and/or for an aircraft component, in particular for an electric drive unit.

In the case of a vehicle component, the advantages mentioned above are particularly beneficial since these components must be protected from dirt, such as dirt particles and in particular aggressive liquid, gaseous and/or solid media, occurring in the environment, for example on the route, in particular on the road and/or rail route and/or waterway and/or air route.

In particular, vehicle components are exposed to a wide variety of aggressive media, such as salty water, in particular salty splash water and/or sea water and/or slush mixed with road salt, and must be protected against these.

For example, in the case of vehicle components, particularly in the interior thereof, parts must also be effectively protected against the ingress of moisture, which may occur, for example, during rain and/or when the vehicle is washed and/or which may occur due to water surrounding the vehicle.

In particular, the above-mentioned object is also achieved by a vehicle component, in particular a ship component and/or a motor vehicle component, for example an automobile component, and/or a rail vehicle component and/or an aircraft component, which comprises an assembly with one or more of the above-mentioned, for example, optional features and/or in which a sealing element comprising a one-piece sealing body with one or more of the above-mentioned, for example, optional features is used.

In some advantageous embodiments, the vehicle component is an electric drive unit.

In particular, the assembly in the electric drive unit forms a housing in the interior of which an electric drive is provided and, for example, arranged.

The above-mentioned advantages are particularly beneficial for the electric drive unit, since the electric drive must be particularly effectively protected against unwanted media, such as dirt and especially moisture.

In particular, the above-mentioned object is also achieved in embodiments of the invention by a vehicle, in particular a motor vehicle, for example an automobile, and/or a ship, for example a ferry, and/or a rail vehicle and/or an aircraft, which comprises an assembly with one or more of the above-mentioned, for example, optional features and/or in which a sealing element comprising a one-piece sealing body with one or more of the above-mentioned, for example, optional features is used.

As already explained above, the above-mentioned features have a particularly positive effect on the vehicle.

Above and below, features and/or elements which are described as being provided by way of example and/or in particular and/or conveniently and/or advantageously and/or preferably and/or the like are features and/or elements which are not absolutely necessary for the success of the basic inventive idea, but which represent, for example, advantageous inventive developments.

A in the 1 to 4 The exemplary embodiment of an assembly designated as a whole by 100 comprises at least two components 112 and 114 and a sealing element 116 for sealing between the at least two components 112, 114 in a sealing region 118.

In particular, in the sealing region 118, a sealing section 122 of the one component 112 and a sealing section 124 of the other component 114 are arranged opposite one another and, for example, at least partially adjacent to one another, as shown by way of example in the enlarged illustration of the sealing region 118 in the 2 is shown.

In particular, two spatial regions 132 and 134 are separated from one another by the two components 112 and 114, wherein these two spatial regions 132 and 134 are at least partially still connected to one another by a gap 136 in the sealing region 118 and in particular between the two sealing sections 122 and 124, as long as the sealing element 116 is not arranged in a sealing manner between the two components 112 and 114.

In an assembled and sealed state of the assembly 100, the sealing element 116 seals in the sealing area 118 between the two components 112 and 114 and in particular the sealing element 116 interrupts the connection of the two spatial areas 132, 134 through the gap 136, so that the gap 136 is at least substantially impermeable to undesirable media, in particular to dirt and/or liquids.

For example, the two components 112 and, in variants, advantageously further components of the assembly 100 form a housing in which an interior space 142 is defined, as for example in 1 is shown.

The interior space 142 is at least partially delimited by the components 112 and 114 and is sealed in the sealing region 118 to the outside, in particular with respect to an environment 144 of the housing formed by the assembly 100, by the sealing element 116.

In particular, one of the spatial regions 132, 134, here for example the spatial region 132, is the interior space 142 and the other spatial region 132, 134 separated from the two components 112, 114 and the sealing element 116, here for example the spatial region 134, is a spatial region of the environment 144 of the housing.

In other variants of the embodiment, it is provided that in the sealing region 118 the one interior space 142 is separated from another interior space which is defined by at least some components of the components 100, or from another spatial region defined by components of this assembly 100.

Advantageously, the assembly 100 is designed and constructed for protecting a particular electrical component, for example an electric drive, wherein the component is advantageously arranged in the interior space 142.

In some variants, it is provided that at least the two components 112 and 114 form a fluid guide line for guiding a fluid in a flow space. In this case, one of the spatial areas, for example the spatial area 132, is at least one spatial area of the flow space and the spatial area of the flow space is separated in a fluid-tight manner in the sealing area 118 by the two components 112 and 114 and the sealing element 116 from a spatial area outside the flow space, here for example from the spatial area 134. For example, the spatial area outside the flow space is in turn a spatial area defined by components of the assembly 100 or a spatial area of an environment 144 of the assembly 100.

In particular, the sealing region 118 extends at least partially elongated in a longitudinal direction 152.

Advantageously, the sealing region 118 comprises a plurality of sections and the longitudinal direction 152 is oriented in different directions in the different sections, so that the sealing region 118 composed of the plurality of sections extends circumferentially and in a self-contained manner around one of the spatial regions 132, 134, here for example around the spatial region 132 of the interior space 142.

In a transverse direction 154, which in particular runs at least approximately perpendicular to the longitudinal direction 152, the two spatial regions 132 and 134 in the sealing region 118 are arranged opposite one another and in particular the gap 136 between the two components 112 and 114 is arranged in the transverse direction 154 between the two spatial regions 132 and 134.

In particular, in several sections of the sealing region 118, the transverse direction 154 is oriented differently in different sections according to the respective different orientation of the longitudinal direction 152 in the different sections.

In particular, the respective sealing sections 122, 124 of the two components 112 and 114 extend elongated in the longitudinal direction 152 in accordance with the design of the sealing region 118 and have a width extension in the transverse direction 154. In particular, the width extension is smaller, in particular significantly smaller, for example at least ten times smaller, than an extension of the sealing sections 122, 124 in the longitudinal direction 152.

In a vertical direction 156, the two components 112, 114 with their respective sealing sections 122, 124 are arranged opposite one another in the sealing region 118.

In particular, the vertical direction 156 runs at least approximately perpendicular to the longitudinal direction 152 and at least approximately perpendicular to the transverse direction 154.

The sealing element 116 comprises a one-piece sealing body 172, designated as a whole by 172, which is exemplary in 3 is shown.

In particular, the sealing body 172 is made of a flexible sealing material, preferably a soft sealing material. For example, the sealing material of the sealing body 172 comprises at least one elastomer.

In particular, the sealing body 172 extends longitudinally in an extension direction 174, wherein the longitudinal extension of the sealing body 172 in the extension direction 174 advantageously corresponds substantially to the elongated course of the sealing region 118 in the longitudinal direction 152.

The sealing body 172 has a particularly varying thickness in a thickness direction 176. In a width direction 178, the sealing body 172 has a particularly varying width extension.

In particular, the extension direction 174 and the thickness direction 176 and the width direction 178 each run at least approximately perpendicular to one another.

In particular, the thickness of the sealing body 172 varies along its extension in the width direction 178.

In particular, the width of the sealing body 172 varies along its extension in the thickness direction 176.

In favorable variants of the embodiment, the sealing body 172 has along the extension direction 174 with respect to cross sections which in the thickness direction 176 and/or in the width direction 178, have an at least substantially constant cross-sectional shape.

In particular, in a properly installed state of the sealing element 116 and in the sealed state, the thickness direction 176 of the sealing body 172 and the vertical direction 156 of the sealing region 118 are aligned at least approximately parallel to one another and the width direction 178 of the sealing body 172 and the transverse direction 154 of the sealing region 118 are aligned at least approximately parallel to one another.

In particular, the sealing body 172 is installed in the vertical direction 156 between the two sealing sections 122, 124 of the components 112, 114 in the installed and sealing state.

Advantageously, the sealing body 172 comprises a main sealing bead 212 and at least one secondary sealing bead 214.

A sealing body 172 with exactly one secondary sealing bead 214 is shown in one variant by way of example in 3 shown.

The main sealing bead 212 has two sealing sides 224 and 226 opposite one another in a sealing direction 222, wherein in the installed and sealing state the sealing sides 224, 226 of the main sealing bead 212 sealingly abut a respective main sealing surface 234 and 236 of the two sealing sections 122, 124. In particular, the main sealing bead 212 forms a main seal 238 between the two components 112, 114 with the main sealing surfaces 234, 236 of the sealing sections 122, 124.

In this embodiment, the sealing direction 222 is preferably oriented at least approximately parallel to the thickness direction 176 and the vertical direction 156. In particular, a thickness of the main sealing bead 212 is measured as the thickness between the two sealing sides 224 and 226.

For example, the main sealing bead 212 is elongated in the sealing direction 222 compared to its extension transverse to the sealing direction 222, for example, an extension of the main sealing bead 212 in the sealing direction 222 is at least twice as large as its extension transverse to the sealing direction.

Preferably, the main sealing bead 212 has at least one sealing lip on each of its two sealing sides 224 and 226, here for example two sealing lips 242 and 244 on one sealing side 224 and two sealing lips 246 and 248 on the other sealing side 226.

In particular, a respective sealing lip 242, 244, 246, 248 is a formation of the main sealing bead 212 that protrudes on the respective sealing side 224, 226 in the sealing direction 222.

The secondary sealing bead 214 has two sealing sides 262 and 264 opposite one another in the sealing direction 222, wherein in the installed and sealing state the sealing sides 262 and 264 of the secondary sealing bead 214 sealingly abut against a respective secondary sealing surface 266 and 268 of the two sealing sections 122 and 124. In particular, the secondary sealing bead 214 with the secondary sealing surfaces 267, 268 of the sealing sections 122, 124 forms a secondary seal 272 between the two components 112, 114.

Preferably, in this embodiment, a thickness of the secondary sealing bead 214 is measured as a thickness between the two sealing sides 262, 264.

Preferably, the secondary sealing bead 214 has at least one sealing lip on each of its sealing sides 262, 264, here, for example, a sealing lip 276 on the sealing side 262 and a sealing lip 278 on the opposite sealing side 264.

In particular, the sealing lips 276, 278 on the corresponding sealing sides 262, 264 of the secondary sealing bead 214 are protruding formations of the respective sealing side 262, 264 formed from the secondary sealing bead 214 in the sealing direction 222.

In particular, the main sealing bead 212 has a greater extent in the sealing direction 222 than the secondary sealing bead 214, wherein the extent of the main sealing bead 212 in the sealing direction 222 is, for example, at least twice as large, preferably at least three times as large, as the extent of the secondary sealing bead 214 in the sealing direction 222.

In this embodiment, the respective extension in the sealing direction 222 of the main sealing bead 212 and the secondary sealing bead 214 corresponds to a respective thickness of the main sealing bead 212 and the secondary sealing bead 214, respectively.

The main sealing bead 212 and the secondary sealing bead 214 extend longitudinally in the extension direction 174 corresponding to the longitudinal extension of the sealing body 172 and are arranged next to one another transversely to the sealing direction 222. In this embodiment, they are therefore particularly arranged next to each other in the width direction 178.

In variants, the secondary sealing bead 214 is formed directly onto the main sealing bead 212.

The secondary sealing bead 214 is formed onto the main sealing bead 212 in particular via a connecting part 288.

For example, the connecting part 288 has a smaller extension in the sealing direction 222 than the secondary sealing bead 214. In particular, in this embodiment, the connecting part 288 has a smaller thickness than the secondary sealing bead 214.

In particular, the connecting part 288 extends longitudinally in the extension direction 174 corresponding to the longitudinal extension of the sealing body 172.

In particular, the connecting part 288 is formed transversely to the sealing direction 222, in particular in this embodiment in the width direction 178, on opposite sides on the one hand on the main sealing bead 212 and on the other hand on the secondary sealing bead 214.

For example, the secondary sealing bead 214, in particular with the connecting part 288, is an arm extending from the main sealing bead 212 transversely to the sealing direction 222.

In particular, the secondary sealing bead 214 is formed onto the main sealing bead 212 at an end of the main sealing bead 212 relative to the sealing direction 222.

Advantageously, a sealing side 224 of the main sealing bead 212, which is located at the end of the main sealing bead 212 to which the secondary sealing bead 214 is formed, and a sealing side 262 of the secondary sealing bead 214 oriented in the same direction are formed at least substantially at the same level with respect to the sealing direction 222.

Advantageously, an end face of the sealing body 172 relative to the sealing direction 222 forms a sealing side 224 of the main sealing bead and a sealing side 262 of the secondary sealing bead 214, which are oriented in the same direction and, in particular, are located at the same level relative to the sealing direction 222.

In particular, at least one sealing side of the secondary sealing bead 214 and the main sealing bead 212, which are oriented in the same direction with respect to the sealing direction 222, are formed at different levels with respect to the sealing direction 222. The corresponding sealing side, here the sealing side 264, of the secondary sealing bead 114 is set back with respect to the corresponding sealing side, here the sealing side 226, of the main sealing bead 212 in the sealing direction 222.

Advantageously, one sealing side, here the sealing side 226 of the main sealing bead 112, relative to which one sealing side, here the sealing side 264 of the secondary sealing bead 214, is set back, forms alone an end face of the sealing body 172 relative to the sealing direction 222.

In particular, one sealing side, here the sealing side 264 of the secondary sealing bead 214, is set back in the sealing direction 222 considerably beyond the sealing side oriented in the same direction, here the sealing side 226 of the main sealing bead 212. In particular, it is set back so far that this set-back sealing side 266 is located closer in the sealing direction 222 to the sealing side opposite it, here the sealing side 262 of the secondary sealing bead 214, and/or closer to the opposite sealing side of the other bead, here the sealing side 224 of the main sealing bead 212, than to the sealing side with the same orientation, here the sealing side 226 of the main sealing bead 212.

In advantageous variants of the embodiment, the sealing body 172 extends to an end 294 of the gap 136, wherein at the end 294 of the gap 136 the gap 136 merges into the adjacent spatial region 132, 134.

In particular, in this embodiment, the sealing body 172 extends with its secondary sealing bead 214 to the end 294 of the gap 136.

Even in advantageous variants of the embodiments explained below, the sealing element 116, in particular its sealing body 172, extends to at least one end of the gap 136, at which the gap 136 merges into one of the adjacent spatial areas 132, 134. Depending on the variant, the sealing element 116, in particular the sealing body 172, extends with a secondary sealing bead 214 and/or with a main sealing bead 212 and/or another part of the sealing element 116, for example a part of the sealing body 172, to at least one end of the gap 136.

In particular, the sealing body 172 is flush with the two components 112, 114 on at least one side of the assembly 100 which faces an adjacent spatial region 132, 134, in particular at the end 294 of the gap 136.

In advantageous variants of the embodiments explained below, the corresponding sealing element 116, in particular its sealing body 172, also ends flush with the two components 112, 114 on at least one side of the assembly 100 which faces one of the adjacent spatial regions 132, 134, in particular in the region of one end of the gap 136.

Advantageously, no dead space is formed at the end 294 of the gap 136.

In particular, at least one of the two components 112, 114 has in its sealing section 122, 124, here for example the component 112 in its sealing section 122, a recess 318 extending in a recess direction 312 from a recess opening 314 to a recess bottom 316.

In particular, the recess direction 312 is oriented at least approximately parallel to the sealing direction 222 and thus the recess 318 in this embodiment extends, for example, in the vertical direction 156.

Transversely to the recess direction 312, the recess 318 is delimited on each side by a respective wall segment 322 and 324, so that the recess 318 is arranged between the two wall segments 322 and 324 in this direction, which here is in particular oriented at least approximately in the same direction as the transverse direction 154.

The sealing body 172 is preferably arranged with its main sealing bead 212 at least partially in the recess 318. The sealing body 172 preferably engages with the part arranged in the recess 318 starting from the recess opening 314 on the recess base 316 in the recess 318. The sealing body 172 advantageously lies sealingly against the recess base 316 in the installed and sealed state.

Advantageously, the recess bottom 316 forms a sealing surface of the component, here for example the main sealing surface 236.

Advantageously, the wall segments 322 and 324 extend in a direction oriented at least substantially parallel to the recess direction 312 up to a respective end face 326 or 328 facing the sealing section of the other component.

In particular, an end face of one of the wall segments, here for example the end face 326 of the wall segment 322, forms a sealing surface of the component, here for example the secondary sealing surface 268.

Thus, in particular in the case of the sealing section 122, its main sealing surface 236 and its secondary sealing surface 268 are formed at different position levels with respect to the sealing direction 222.

In particular, in this exemplary embodiment, the sealing surfaces of a component, here for example the main sealing surface 234 and the secondary sealing surface 266 of the component 114, are formed by a common surface segment 342 of the sealing section 124. This surface segment 342 advantageously has a surface that runs at least approximately perpendicular to the sealing direction 222 and forms these sealing surfaces 234 and 266.

Thus, in particular the main sealing surface 234 and the secondary sealing surface 266 of this component 114 are formed at the same position level with respect to the sealing direction 222.

In particular, the main sealing surfaces 234 and 236 of the two components 112 and 114 are arranged opposite each other in the sealing direction 222 and the secondary sealing surfaces 266 and 268 of the components 112 and 114 are arranged opposite each other in the sealing direction 222.

Advantageously, the sealing body 172 is at least partially pressed between the two sealing sections 122 and 124 in the sealing direction 222.

In particular, the main bead 212 is pressed between the main sealing surfaces 234 and 236 of the sealing sections 122, 124 in the sealing direction 222.

Advantageously, the at least one sealing lip of the respective sealing side of the main sealing bead, in this case the sealing lips 242 and 244 on the sealing side 224 and the sealing lips 246 and 248 on the sealing side 226, together with the respective main sealing surface 234, 236, against which the respective sealing side 224, 226 rests with the sealing lip, forms a respective main sealing line 352, 354, 356, 358 of the main seal 238.

In particular, the secondary sealing bead 214 is pressed between the secondary sealing surfaces 266 and 268 of the sealing sections 122, 124 in the sealing direction 222.

Advantageously, at least one sealing lip of the respective sealing side of the secondary sealing bead forms, here for example the sealing lip 276 of the sealing side 262 and the sealing lip 278 of the sealing side 264, with the respective secondary sealing surface 246, 268, against which the corresponding sealing side 262, 264 rests, form a respective secondary sealing line 366, 368 of the secondary seal 272.

In particular, at a respective sealing line, here for example at the main sealing lines 352, 354, 356, 358 and at the secondary sealing lines 366 and 368, a region of increased compression of the sealing body 172 is formed, at which an increased sealing effect is advantageously achieved.

In particular, the connecting part 288 between the main sealing bead 212 and the secondary sealing sausage 214 is at least substantially not pressed even in the pressed state of the sealing body 172.

In this case, in particular an extension of the connecting part 288 in the sealing direction 222, in this case in particular a thickness of the connecting part 288, is smaller than or at most substantially equal to the extension of the secondary sealing bead 214 in its pressed state.

Preferably, the two sealing sections 122 and 124 of the two components 112 and 114 lie directly against each other with respective frictional surfaces 382 and 384.

In particular, the frictional surfaces 382 and 384 of the sealing sections 122 and 124 are opposite surfaces and each run at least approximately perpendicular to the sealing direction 222.

In particular, a main frictional connection between the two components 112 and 114 in the sealing area 118 takes place via the two frictional connection surfaces 182, 184 and the sealing body 172 is arranged in the secondary frictional connection.

Preferably, the frictional connection surface 382 of the sealing section 122 with the recess 318 is formed on the end face 328 of a wall segment 324, wherein this wall segment 324 is the other wall segment delimiting the recess 318 than that wall segment 322 on which the secondary sealing surface 268 is formed.

Advantageously, the wall segment 324 with the frictional connection surface 382 extends further in the direction of the other sealing section 124 by a distance 388 in the sealing direction 222 than the wall segment 322 with the secondary sealing surface 268. Preferably, the distance 388 corresponds to an extension of the secondary sealing bead 214 in the sealing direction 222 in the pressed state.

The frictional connection surface 384 of a sealing section 124 is formed, for example, on the surface segment 342, which also forms the main sealing surface 234 and the secondary sealing surface 266 of this sealing section 214.

For example, the frictional connection surfaces 382 and 384 of the components 112 and 114 are formed in the region of an end 394 of the gap 136, wherein at the end 394 the gap 136 merges into an adjacent spatial region 132, 134.

Advantageously, the frictional connection surfaces 382 and 384 of the components 112, 114 are designed such that no dead space is formed at the end 394 of the gap 136 at which the frictional connection surfaces 382 and 384 are formed.

In particular, the gap 136 extends between the ends 294 and 394.

For example, ends 294 and 394 are opposite ends of gap 136.

In some variants of this embodiment, the main seal 238 is arranged closer to the inner spatial region 132, for example the interior 242, than the secondary seal 272 relative to the direction running transversely to the sealing direction 222, i.e. here in particular relative to the transverse direction 154, so that the secondary seal 272 is arranged closer to the outer spatial region 134, for example the environment 144, than the main seal 238.

In particular, the wall segment 324, which in particular has the frictional connection surface 382, is arranged on a side of the sealing section 122 facing the inner space region 132 and the wall segment 322, which in particular has the secondary sealing surface 268, is arranged on a side of the sealing section 122 facing the outer space region 134.

Such a variant is exemplified in the illustration in the 1 and 2 shown.

In some variants of this embodiment, the main seal 238 is arranged closer to the outer spatial region 134, for example the environment 144, in the direction transverse to the sealing direction 222, in this case in particular in the transverse direction 154, than the secondary seal 272, so that the secondary seal 272 in these variants is arranged closer to the inner spatial region 132, for example the interior 142, than the main seal 238 with respect to the direction running transversely to the sealing direction 222.

In particular, the wall segment 324, which in particular has the frictional connection surface 382, is arranged on a side of the sealing section 122 facing the outer spatial region 134, and the wall segment 322, which in particular has the secondary sealing surface 268, is arranged on a side of the sealing section 122 facing the inner spatial region 132.

Such a variant is also exemplified by the representation in the 2 shown and by appropriate modification of the sealing area 118, the exemplary representation of the 1 representative of such variants.

In particular, the two components 112 and 114 are fastened to one another at several fastening points 412 with fastening elements 414, as shown by way of example in 4 is shown.

In particular, the fastening elements 414 also apply and maintain the pressing force required for pressing the sealing body 172.

In some favorable embodiments, the fastening elements 414 and the fastening points 412 are designed in such a way that excessive compression of the sealing body 172 is prevented. Depending on the variant, the design preventing excessive compression is provided as an alternative or in addition to the design of the sealing sections 122, 124 with frictional connection surfaces 382, 384, via which a main frictional connection takes place.

In particular, the plurality of fastening points 412 are arranged along the course of the sealing region 118 in the longitudinal direction 152.

In particular, a distance between the mutually facing sides of the sealing sections 122 and 124 in the vertical direction 156 is smallest at the fastening points 412 and somewhat larger in the course of the sealing region 118 in the longitudinal direction 152 between the fastening points 412, since, for example, at least one sealing section of a component, such as the sealing section 124 of the component 114, bulges slightly due to the stresses in the sealing region 118.

In particular, different distances between the sealing sections 122 and 124 in the sealing direction 222 are compensated by the elasticity of the sealing body 172, in particular the elasticity of its main sealing bead 212 and/or the secondary sealing bead 214, so that along the entire course of the sealing region 118 the sealing body 172 rests sealingly against the respective sealing surfaces 234, 236, 266, 268 and closes the gap 136 between the sealing sections 122 and 124.

In particular, a design and functioning of the components 112 and 114 and the sealing element 116 of the assembly 100 in the sealing area 118 as well as, for example, advantages thereof are briefly summarized as follows.

The components 112 and 114 have a respective sealing section 122, 124 in the sealing region 118, which are arranged opposite one another in particular in the vertical direction 156 and between which a gap 136 is formed.

A spatial region 132, 134 is located laterally, in particular with respect to the transverse direction 154, of the sealing region 118.

The sealing body 172 of the sealing element 116 is arranged in the gap 136 between the two sealing sections 122 and 124 and lies sealingly against sealing surfaces 234, 236, 266, 268 of the sealing sections 122 and 124. Advantageously, the gap 136 is essentially closed to prevent undesirable media, for example liquids and/or dirt particles, from passing through from one of the spatial regions 132, 134 located to the side of the sealing region 118 into the other spatial region 134, 132, in particular transversely to the sealing direction 222.

Advantageously, a main seal 238 and at least one secondary seal 272 offset transversely to the sealing direction 222 are formed by the sealing sections 122 and 124 and the sealing element 116, in particular by the sealing body 172, in order to increase the sealing effect of the seal.

For example, in variants of the embodiment, a secondary seal 272 is arranged transversely to the sealing direction 222 with respect to a transition from one of the spatial regions 132, 134 to the other of the two spatial regions 134, 132 and with respect to a passage direction in front of the main seal 238,

The direction of passage is oriented from the spatial region 132, 134 from which the undesired medium originates, in the direction of the spatial region 132, 134 which is to be protected from this undesired medium.

In particular, one advantage of this is that the unwanted medium must first overcome the secondary seal 272, and thus less of the unwanted medium reaches the main seal 238, which can thereby more effectively protect the corresponding spatial area 132, 134 from the unwanted medium.

In some advantageous variants, a secondary seal 272 is arranged after the main seal 238 with respect to the passage direction.

In particular, one advantage of this is that any residual portions of the undesirable medium that were not blocked by the main seal 238 and that could pass through the main seal 238 in the direction of passage are stopped by the secondary seal 272, so that the spatial region 132, 134 to be protected is even better protected from the undesirable medium.

In particular, the main seal 238 and the secondary seal 272 are at least partially formed at different position levels with respect to the sealing direction 222.

Advantageously, the path through which the undesirable medium has to pass in order to overcome the seal becomes longer and geometrically more complex, thereby increasing the sealing effect of the seal.

For example, by designing the main seal 238 and the secondary seal 272 at least partially at different position levels, the seal can be made more compact.

In particular, for this purpose, at least one of the sealing sections 122, 124 has at least two sealing surfaces against which the sealing body 172 rests in a sealing manner, wherein the at least two sealing surfaces are located at different position levels with respect to the sealing direction 222, such as here, for example, the main sealing surface 236 and the secondary sealing surface 268 of the sealing section 122.

Advantageously, the sealing body 172 has different dimensions in different areas in the sealing direction 222, here for example different thicknesses of the main sealing bead 212 and the secondary sealing bead 214, in order to be able to have a sealing effect at different position levels with respect to the sealing direction 222.

It is particularly favorable if at least one sealing section 122, 124 has a recess 318 in which the sealing body 172 is partially arranged in the sealing state, wherein advantageously at least one sealing surface is formed in the recess 318.

In particular, the recess 318 allows the formation of seals at different position levels with respect to the sealing direction 222 to be realized particularly favorably.

For example, one advantage of the recess 318 is that the sealing body 172 partially arranged therein is held at least substantially true to position.

Advantageously, in the installed and sealing state, the sealing body 172 is pressed in the sealing direction 222 at least in the region of the seals at different position levels, here in particular in the region of the main seal 238 and the secondary seal 272.

In advantageous variants, the two sealing sections 122, 124 with frictional connection surfaces 382 and 384 are arranged on one another in a direct force-transmitting manner, for example in direct contact, so that a main force connection between the components 112 and 114 can take place via the frictional connection surfaces 382, 384 and the sealing body 172 is arranged in the force shunt.

In further embodiments explained in more detail below, those elements and features which are at least substantially identical in design and/or which at least substantially fundamentally fulfill the same functions as in another embodiment, in particular in the embodiment explained above or, for example, in another of the further embodiments, are provided with the same reference numerals and, in order to avoid repetition, with regard to more detailed information on such elements and/or features, reference is made in full to the description in connection with the embodiment explained above and/or the other further embodiments, unless a statement in another embodiment is obviously not compatible with the design in the further embodiment.

In particular, the components 112, 114 and the sealing element 116 of the embodiments explained below are part of an assembly 100, which forms, for example, a housing with an interior 142, as described above in particular in connection with the 1 and 4 explained, so that these explanations also apply to favorable variants of the embodiments explained below and the 1 and 4 are also representative of the embodiments explained below.

A second embodiment of an assembly 100a comprising at least two components 112 and 114 and a sealing element 116 for sealing between the two components 112 and 114 in a sealing area 118 is exemplary in variants in the 5 and 6 shown, wherein a sealing body 172a of the sealing element 116 is shown by way of example in 7 is shown.

In particular, in the second embodiment, the sealing body 172a has two secondary sealing beads 214 I and 214 II, which are arranged transversely to the sealing direction 222, here in particular in a width direction 178 of the sealing body 172a, on both sides of a main sealing bead 212 of the sealing body 172a and are formed directly or indirectly onto the main sealing bead 212.

In particular, the sealing direction 222 is oriented at least approximately parallel to the vertical direction 156 and/or the thickness direction 176.

In particular, at least one of the secondary sealing beads 214 is at one end of the extension of the main sealing bead 212 in the sealing direction.

In some advantageous variants, the secondary sealing beads 214 I and 214 II are arranged at least substantially at the same position level with respect to the sealing direction 222, as shown by way of example in the 5 to 7 is shown.

In other advantageous variants, the two secondary sealing beads 214 I and 214 II are arranged at different position levels with respect to the sealing direction 222, as will also be explained below in connection with further embodiments.

Advantageously, a sealing side 224 of the main sealing bead 212 and at least one sealing side 262 of a secondary sealing bead 214 or a respective sealing side 262 I, 262 II of the two secondary sealing beads 214 I, 214 II are formed by an end face of the sealing body 172a related to the sealing direction 222, in particular if the one secondary sealing bead 214 or both secondary sealing beads 214 is/are arranged at one end of the extension in the sealing direction 222 of the main sealing bead 212.

In particular, in each of the secondary sealing beads 214 I and 214 II, at least one of their sealing sides 262 and 264 is retracted in the sealing direction 222 relative to a sealing side, here relative to the sealing side 226, of the main sealing bead 212.

Advantageously, the main sealing bead 212 and/or at least one secondary sealing bead 214 has at least one sealing lip 242, 244, 246, 248, 276, 278 on their respective sealing sides 224, 226, 244, 266.

Advantageously, each of the sealing sections 122 and 124 of the components 112 and 114 has a main sealing surface 234, 236 for the main seal 238, here in particular for the main sealing bead 212, and for each of the secondary seals 272 I and 272 II, thus in particular for each of the secondary sealing beads 214 I and 214 II, a respective secondary sealing surface 266 I, 266 II, 268 I, 268 II.

Advantageously, in at least one sealing section, here for example in the sealing section 124a, the main sealing surface 234 and at least one secondary sealing surface 266 are formed by a common surface segment 342 of the sealing section.

In some advantageous variants, the common surface segment 342 forms the main sealing surface 234 and the two secondary sealing surfaces 246 I and 266 II, in particular when the two secondary sealing beads 214 I and 214 II are arranged at one end of the extension of the main sealing bead 212.

This is exemplified in the 5 and 6 shown.

In other favorable variants, the common surface segment 342 forms the main sealing surface 234 and one of the secondary sealing surfaces 266 and in particular a further segment of the sealing section 124a forms the further secondary sealing surface 266, wherein the further segment protrudes in particular in the sealing direction 222 beyond the common surface segment 342 in the direction of the other sealing section 122a. In particular, this is provided if one of the secondary sealing beads 214 is arranged at one end of the extension in the sealing direction 222 of the sealing body 212 and the other secondary sealing bead 214 is arranged offset in the sealing direction 222.

Preferably, at least one sealing section, here for example the sealing section 122a, has a recess 318 in which the sealing body 172a is at least partially arranged and wherein the recess 318 preferably has at least one sealing surface.

In particular, the main sealing bead 212 is at least partially arranged in the recess 318 and has at least one main sealing surface 236.

In particular, wall segments 322 and 324 of the sealing section 122a, which are arranged on both sides of the recess 318 and in particular which delimit these, form a secondary sealing surface 268 I and 268 II.

Preferably, a respective end face 326, 328 of the wall segments 323, 324 facing the other sealing section 124a forms a respective secondary sealing surface 248 I, 248 II.

In some favorable variants, the two wall segments 322 and 324 extend at least substantially equally far in the direction of the other sealing section 124a, i.e. here they extend in particular at least approximately equally far in the sealing direction 222 and/or the vertical direction 156, up to the respective sealing surface 268, as shown by way of example in the 5 and 6 is shown.

In other favorable variants, in particular when the secondary sealing beads 214 I and 214 II are arranged offset from one another in the sealing direction 222 and/or have different extensions in the sealing direction 222, the two wall segments 322 and 324 extend to the respective secondary sealing surface 268 I and 268 II to different distances in the sealing direction 222.

In particular, the sealing lips 242, 244, 246, 248, 276, 278 form a corresponding sealing line 352, 354, 356, 358, 366, 368 with the respective sealing surface 234, 236, 266, 268.

In particular, the sealing body 172b has a main sealing bead 212 and a secondary sealing bead 214, wherein the secondary sealing bead 214 is formed directly or indirectly onto the main sealing bead 214 with respect to a sealing direction 222 between two ends of an extension of the main sealing bead 214.

Advantageously, the secondary sealing bead 214 is arranged transversely to the sealing direction 222 next to the main sealing bead 212.

For example, the sealing direction 222 is oriented at least substantially parallel to the vertical direction 156 and/or the thickness direction 176.

Advantageously, the main sealing bead 214 has sealing sides 224 and 226 arranged opposite one another in the sealing direction 222, and the secondary sealing bead 214 has sealing sides 262, 264 arranged opposite one another in the sealing direction 222.

For example, a respective end face of the sealing body 172b relative to the sealing direction 222 forms a respective sealing side 224 and 226, in particular of the main sealing bead 212.

In particular, the sealing sides 262 and 264 of the secondary sealing bead 214 are located at different position levels with respect to the sealing direction 222 than the sealing sides 224 and 226 of the main sealing bead 212, in particular because the sealing sides 262, 264 are located retracted.

Advantageously, the sealing sides 224, 226, 262, 264 of the main sealing bead 212 and/or secondary sealing bead 214 each have at least one sealing lip 242, 244, 246, 248, 276, 278.

In particular, the sealing sections 122b and 124b of the components 112 and 114 each form at least one main sealing surface 234, 236, in particular for the main sealing bead 212, and a secondary sealing surface 266, 268, in particular for the secondary sealing bead 214.

Advantageously, the recess 318, in particular on its recess bottom 316, has a sealing surface against which the sealing body 172b rests in a sealing manner, here for example the main sealing surface 236 for the sealing contact of the main sealing bead 212.

Advantageously, one of the wall segments at least partially delimiting the recess 318, here for example the wall segment 322, forms a secondary sealing surface 268, in particular for the sealing contact of the secondary sealing bead 214.

In particular, the secondary sealing surface 266 of this sealing section 124b is formed on a segment of the sealing section 124b, which is in particular a protruding segment 452 and/or a wall segment 122', wherein this segment protrudes in the sealing direction 222 beyond the main sealing surface 234 of this sealing section 124b in the direction of the other sealing section 122b.

Advantageously, in one sealing section, here in the sealing section 122b, the frictional connection surface 382 is formed on an end face 328 of the wall segment 324, which at least partially delimits the recess 318 but does not form the sealing surface 268.

In some advantageous variants, the frictional connection surface 384 of the one sealing section 124b is formed on a same surface section thereof as the main sealing surface 234, so that a common surface segment 342 forms these two surfaces 384, 234, as shown by way of example in the 8th shown variant.

In some favorable variants, the segments with the respective frictional connection surface 382 and 384 each protrude beyond the segment with the respective secondary sealing surface 268, 266, for example when the respective segment with a frictional connection surface 382 and 384 protrudes in the sealing direction 222 beyond the position level of the sealing surface 268, 266 of its own sealing section 122, 124 but does not protrude to the position level of the sealing surface 266, 268 of the other sealing section 124, 122. In particular, a position level in the sealing direction 222 at which the two frictional connection surfaces 384, 382 contact each other is then located between the position levels of the two secondary sealing surfaces 266 and 268.

For example, here the sealing side 264 of the secondary sealing bead 214 is so far behind the sealing side 226 of the main sealing bead 212 is retracted such that the sealing side 224 of the main sealing bead 212 oriented in the other direction is closer to the sealing side 226 of the main sealing bead 212 than the retracted sealing side 264 of the secondary sealing bead 214. In addition, for example, here the sealing side 224 of the main sealing bead is retracted so far in the sealing direction 222 behind the sealing side 262 of the secondary sealing bead 214 that the sealing side 264 of the secondary sealing bead 214 oriented in the other direction is closer to the sealing side 262 in the sealing direction 222 than the retracted sealing side 224 of the main sealing bead 214, as shown by way of example in 12 is shown.

The step 472 is formed on a side of the segment which faces the sealing surfaces 236, 268 of the other sealing section 122d.

For example, the segment with the sealing surfaces 234, 266 is a wall segment 322", from which a segment 452" extends even further in the direction of the other sealing section 122d.

In particular, in this segment 322", 452", a sealing surface, here the main sealing surface 234, is set back transversely to the sealing direction 222 relative to another sealing surface, here the secondary sealing surface 266.

In some advantageous variants of the embodiments explained above, at least one recess 512 is provided as explained below.

Elements and/or features described in connection with one or more of the embodiments explained above are also optionally provided in variations of the embodiments explained below.

In particular, the at least one recess 512 in at least one of the sealing sections 122, 124 of the components 112 and 114 is designed as a barrier for a medium, in particular a liquid medium, against which sealing is to be and/or is being carried out. The recess 512 is advantageously designed as a groove or gap in the sealing section 122, 124.

Advantageously, the recess 512 is designed such that the flow of a medium that has penetrated the main seal 238 and/or the secondary seal 272 is at least made more difficult or even stopped. In particular, the recess 512 is designed such that a combination of adhesion forces and/or cohesion forces and/or the surface tension of the medium holds the medium to the recess 512.

In particular, the recess 512 extends in the sealing direction 222 into the sealing portion 122, 124 on which this recess 512 is formed.

For example, in some advantageous variants, a recess 512 designed as a barrier for a medium is formed only in the sealing section 122, 124 of one of the two components 112, 114, as shown by way of example in the 16 , 17 is shown.

In some preferred variants, a recess 512 I, 512 II is formed in each of the sealing sections 122, 124 of the two components 112, 114, as shown by way of example in the 18 , 19 is shown.

In particular, the recess 512 is formed transversely to the sealing direction 222 between the main sealing surface 234, 236 and the secondary sealing surface 266, 268.

In some preferred variants, the sealing surfaces 234, 236, 266, 268, which are formed on the same sealing section 122, 124 as the recess 512 and on both sides of the recess 512, are formed at an at least substantially equal height level with respect to the sealing direction 222, as shown by way of example in the 16 and in the 18 and 19 for the sealing surfaces on the sealing section 124.

In some advantageous variants, the sealing surfaces 234, 236, 266, 268, which are formed on the same sealing section 122, 124 as the recess 512 and on both sides of the recess 512, are formed at different height levels with respect to the sealing direction 222, as shown by way of example in the 17 for the sealing surfaces on the sealing section 124 and in the 18 and 19 for the sealing surfaces on the sealing section 122 is shown as an example.

In some advantageous variants, not explicitly shown in the drawing, a recess 512 I and 512 II is formed on the sealing sections 122, 124 of the two components 112, 114 and the respective sealing surfaces 234, 236, 266, 268 are formed on both sealing sections 122, 124 at different height levels relative to the sealing direction 222.

In particular, the region of the gap 136 in which the recess 512 is formed is bridged by a connecting part 288 of the one-piece sealing body 172. The connecting part 288 connects the part of the sealing body 172 which at least co-forms the main seal 238 with the part of the sealing body 172 which at least co-forms the secondary seal 272.

Preferably, variants of embodiments with at least one recess 512, which is designed as a barrier for a medium, are otherwise at least partially designed as explained above in connection with one of the several embodiments and/or at least partially as in the 16 to 19 shown trained. In particular, in order to avoid repetition, reference is made in full to the above statements with regard to advantageous designs, in particular with regard to advantageous designs of the sealing sections 122, 124, for example with at least one recess 318 for at least a part of the sealing body 172 and/or favorable designs of segments 322, 324, 342, 452, 462, 464, and/or advantageous designs of the sealing body 172, for example of sealing sides 224, 226, 262, 264 with preferably at least one sealing lip 242, 244, 246, 248, 276, 278 and/or parts of the sealing body 172 for the main seal 238 and/or secondary seal 272, for example a main sealing bead 212 and/or secondary sealing bead 214, and/or with regard to orientations of Directions 152, 154, 156, 174, 176, 178 and/or further configurations of the sealing element 116 and/or the components 112, 114 and the assembly 100, for example with respect to the frictional connection and/or the fastening of the components.

In some advantageous variants of the embodiments, a part of the sealing body, which at least forms the main seal 238 or the secondary seal 272, has an engagement recess 522 into which a segment of a sealing section, for example the sealing section 122, engages. Such a variant is shown by way of example in 19 In some favorable variants of the embodiments explained above, which are used in connection with the 1 to 18 explained, a part of the sealing body 172 is designed accordingly. For example, in some favorable variants, a part of the sealing body 172 is provided with an engagement recess 522 instead of a secondary sealing bead 214 and/or instead of a main sealing bead 212 and/or another part.

In particular, the engagement recess 522 has a bottom region 526 and sections of the sealing body 172, for example legs thereof, are formed on both sides of the bottom region 526 and extend on both sides of a free space of the engagement recess 522 away from the bottom region 526.

For example, the part of the sealing body 172 with the engagement recess 522 has a U-shaped profile in a cross section which is taken in particular at least approximately perpendicular to the extension direction 174 of the sealing body 172.

In particular, the sealing section 122, 124, which the engagement recess 522 faces, here for example the sealing section 122, engages with a segment 528 in the engagement recess 522. For example, the engaging segment 528 is a wall segment 322, 324 and/or a protruding segment 452, as explained above.

In particular, the engaging segment 528 has a sealing surface 234, 266 for the primary seal 238 or the secondary seal 272.

Advantageously, a front side of the engaging segment 528 faces a bottom region 526 of the engaging recess 522. Advantageously, the sealing surface 234, 266 is formed on the front side and a sealing side 224, 226, 262, 264 of the sealing body 172 for the main seal 238 and the secondary seal 272 is formed on the bottom region 526.

Advantageously, the engaging segment 528 is pressed into the engagement recess 522 so that the engaging segment 528 presses the sealing body 172 in the region of the engagement recess 522, in particular in the region of the bottom region 526.

Advantageously, lateral legs of the engagement recess 522 encompass the engaging segment 528.

For example, the sealing body 172 is flush with the other component which is arranged opposite the component with the engaging segment 528, here for example with the component 114 on a side facing the adjacent spatial region 132, 134. In particular, the leg of the engagement recess 522 is flush with the other component.

In further advantageous variants and/or embodiments, features and/or elements which are described in one of the embodiments explained above are combined with features and/or elements which are described in another of the embodiments explained above.
