Description

Assembly of connected components

The invention relates to an assembly of connected components in vehicle or body construction with a connecting means for joining the components.

Such assemblies of joined components are in many areas of a vehicle or a body and are known in the art several times.

The standard joining technique for metals, especially in vehicle construction, is welding. Disadvantages associated with this method are particularly apparent when connecting various metallic materials such as in the connection of components made of steel with components of aluminum or magnesium. The usual method is spot welding. However, it requires certain geometric conditions in order to use the welding tools can. In addition, only a selective power transmission between the parts is made possible. Another technique used is laser welding, which enables a surface connection. However, the required application technique is expensive and prone to failure. However, a major disadvantage of all welding processes is the negative influence on the surface quality due to flying sparks and distortions as well as impairment of the material behavior in the heat affected zone.

In addition, mechanical connection techniques are also used in vehicle construction. For example, such an assembly is known from US4,936,409A. The carrier for a vehicle battery disclosed herein is connected to protruding apertured tabs by means of bolts or screws to the body. However, this attachment connects the carrier with the body only pointwise. In addition, the connection by means of screws or bolts can bring problems in a necessary galvanic separation of the components with it.

Increasingly adhesive bonds are used to produce a full-surface power transmission between the parts arranged. The setting time of the adhesives is always a compromise between pumpability and applicability and the required initial adhesion which is necessary for the further assembly process. In vehicle construction, structural adhesives only reach their full joining force when hardened in the paint oven. However, in order to ensure the mechanical strength of the body, which is necessary for the assembly process, it is generally necessary to set weld spots, which in turn entail the disadvantages listed above. It is therefore an object of the present invention to provide an improved joining technique for vehicle construction, which eliminates the aforementioned disadvantages.

This invention is solved by the features of claim 1.

Advantageous embodiments of the invention are specified by the subclaims.

The basic idea of the invention is the use of an assembly of assembled components in vehicle or body construction with connecting means for connecting the components, wherein a first connection of the components is provided by means of a mechanical connection technology and wherein a second connection of the components is provided by means of a material-fitting joining technique.

Preferably, the connection means is provided with means for providing the mechanical connection. In this case, as connection means both for a connection suitable single or multiple Verbindungsbereiche- or members of the components are used, as well as separate components, such as the expert known fasteners, in particular bolts, screws, spring, keyways, wedges, rivets or pins. In the use of a connecting element as a connecting means are in particular components of a plastic such as polyamide, in particular configured with other fillers or as a composite material. Also conceivable is the use of such a connecting element made of a metallic material, such as steel, in particular a high-strength steel. Such a connection element can be used, for example, as a connector for components to be connected.

As a mechanical first connection is between the components or between the components and the connecting means in particular a frictional connection is conceivable. Of course, the mechanical first connection can also be implemented by means of a positive connection. Thus, in particular, a snap-in connections, a tongue-and-groove connection or bung, a dovetail connection or a feather key connection or other types of connection known to the person skilled in the art can be used.

For the cohesive second compound in particular an adhesive connection is provided. In this case, for example, the connecting means, such as connection areas or members of the components or also designed as separate components connecting elements may be at least partially equipped with an adhesive. In addition, the use of a suitable adhesive for the cohesive second connection can ensure, if necessary, galvanic separation of the components of the assembly. be presented. Also, for example, for the cohesive second compound, an adhesive can be used, which is able to connect, for example, components of different materials.

As components to be connected components can be used in particular in vehicle and body construction to be mounted components. For example, a component represent the body and another component, for example, a battery carrier, a cooler or components, especially pipes of the cooling system, an engine mount, a fender receptacle, an axle component, a bumper, hood or trunk holder or other attachments, which To connect to the body is to represent. Also, such an assembly may represent components of a space frame, as well as a roof or roof or floor components that are to be connected to another component, in particular a body.

Conceivable here is a connection of such a second component with the first component, for example during vehicle and / or body assembly via the mechanical first connection means of a mechanical connection technology. This can for example be done without tools and only serve to fix the position of the components to each other. By the cohesive second connection by means of a cohesive joining technique, the components receive the final fixation and final adhesion to each other.

By using a combined mechanical and material connection or joint further advantages can be achieved. For example, the first connection via a mechanical connection technique for fixing the position of the components to be connected to the module can be used relative to each other. However, the second connection via a cohesive joining technique only makes the final attachment between the components. A further advantage is the possibility of providing an immediate connection force via the mechanical connection, which may be necessary, for example, for the assembly process, in combination with the integral connection, which in particular can be designed flat and, for example, takes place only in a later process step.

According to an advantageous development of the invention, it is accordingly provided that the cohesive second connection of the components takes place after the mechanical first connection of the components in order to provide a temporary assembly connection by the mechanical first connection and by the cohesive second connection a final connection of the components of the assembly to achieve.

Another advantage is the use of a structural adhesive for the cohesive second connection by means of cohesive joining technology. Optionally, the structural adhesive be added with Blähstoffen to achieve a wider Abbindefläche. Also, by using such a structural adhesive, any component tolerances arising in the manufacture of the components and / or the connecting means can be compensated during the joining. By the use of adhesives, in particular a surface bonding of the components to be joined can be achieved. Also, there is no negative influence on the surface quality and no heat affected zone with impairment of the material behavior in selbiger when selecting a suitable adhesive in contrast to the usual in vehicle and bodywork welding process.

Structural adhesives are preferably used which, under the conditions of the assembly process of the assembly, for example for the mechanical first connection, do not yet set, but only later, for example, harden by the action of temperature or other forms of energy and provide the cohesive second connection between the components. For this purpose, the structural adhesive can be applied and installed on the mechanical connection means, for example, before or during the assembly process.

Suitable structural adhesives are, in particular, the known high-strength structural adhesives. These are in particular selected from 1- or 2-component adhesives based on crosslinking polyurethanes, epoxy resins and / or anaerobically crosslinking acrylate-containing adhesives. It is also possible to use temperature-stable polyimide adhesives. The adhesives should be stable to temperature and solvents under the conditions of use. Epoxy resin adhesives are adhesives based on epoxy group-containing oligomers or polymers which can crosslink with nucleophilic or electrophilic curing agents, such as, for example, polyamines, polyamides, polymercaptans, polyols or polyphenols. By anaerobic curing adhesives are meant those containing oligomers or polymers having unsaturated double bonds, such as acrylate groups, and wherein free radical crosslinking is initiated by activator / initiator systems and is initiated under anaerobic conditions. As activators redox systems are known, in particular metal-containing systems are suitable. Polyurethane adhesives are to be understood as meaning reactive adhesives based on isocyanate-group-containing polyurethanes which may be in the form of a 2K system or a 1K system. For example, 1-K systems crosslink with water or latent hardeners are activated when exposed to heat. In 2-component systems, isocyanate-containing prepolymers are reacted with curing agents containing nucleophilic, isocyanate-reactive groups, such as OH, NH, SH, COOH groups.

For the structural adhesive it is possible in particular to use suitable polymeric base binders, such as, for example, ethylene-vinyl acetate copolymers (EVA), copolymers of ethylene with (meth) acrylate esters, which may still contain proportional (meth) acrylic acid. lymerized, random or block copolymers of styrene with butadiene or isoprene or their hydrogenation products. The latter can also be triblock copolymers of the type SBS, SIS or their hydrogenation products SEES or SEPS. In addition, the binders may also contain crosslinkers, adhesion promoters, tackifiers, plasticizers and other auxiliaries and additives, such as, for example, low molecular weight oligomers, and these polymeric binders contain propellants to achieve sufficient blowing power and expansion capacity Propellants are in principle all known propellants such as the "chemical blowing agents" which release gases by decomposition or "physical blowing agents", ie expanding hollow spheres Examples of the former blowing agents are azobisisobutyronitrile, azodicarbonamide, di-nitrosopentamethylenetetramine, 4,4 '-Oxybis (benzenesulfonic acid) hydrazide, diphenylsulfone-3,3'-disulfohydrazide, benzene-1,3-disulfohydrazide, p-toluenesulfonyl semicarbazide Examples of the physical blowing agents are expandable plastic microbubbles based on polyvinylidene chloride copolymers or acrylonitrile / (meth) acrylate copolymers, as they are For example, under the name "Dualite" or "Expancel" from the companies Pierce & Stevens and Casco Nobel are commercially available.

Another advantage is the equipment of the connecting means, in particular of fasteners such as screws or bolts for the cohesive second connection by means of cohesive joining technology with a structural adhesive. In particular, threaded portions or other connecting portions or members of such connecting means may be considered with the structural material. The mechanical first connection of the components is provided in this case by the actual mechanical connection technology of the connection means, for example by means of a screw connection. The cohesive second connection is effected by the activation of the structural adhesive, for example by means of a heat action by the paint baking process of the body painting when using a thermally activatable structural material.

Another advantage is the use of a structural adhesive for the cohesive second connection of the components, which additionally provides a frictional connection. In this case, the use of the structural adhesive, for example, already in the non-activated state of the structural adhesive, a friction between the components to be connected, for example, the components or the components provided via a separate connection element. This friction can in particular lead to an adhesive force, so that tensile forces can act on the connected components by this non-positive connection, which can be compensated by the adhesive force of the frictional connection, without the connection dissolves. By virtue of this possibility of providing a frictional connection by the structural adhesive, the mechanical first connection, for example a positive connection, can thus be increased, in particular, even before the activation of the structural adhesive. On the one hand, the choice of adhesive Stoffs be relevant by a structural adhesive, which is preferably provided on or on the connecting means is selected for the cohesive second compound, which is, for example, sticky and tough and in this way already in the non-activated state, the two components with each other positively. On the other hand, the contact surface provided with structural adhesive may be relevant for the cohesive second connection, since the adhesion force of the non-positive connection is greater the larger the contact surface provided with structural adhesive. In addition, the use of an expanding adhesive is conceivable that increases the friction between the components to be connected alternatively or additionally in the expansion to provide the cohesive second connection and thus provides a greater adhesive force and a combined material and non-positive second connection.

Another advantage is the use of a structural adhesive, which has damping and / or damping properties in order to provide insulation and / or damping of the assembly with the cohesive second connection of the components. In particular, this selection of a structural adhesive is suitable for assemblies with mechanically moving parts or running motors, which inevitably set the particular in vehicle and / or body construction to find thin-walled sheets in vibration, which are often in the audible range of the human ear. These vibrations can be transmitted in the form of structure-borne noise over the entire vehicle or the machine or the device and can be emitted at remote locations in the air as disturbing sound.

The specialist working in this area of work distinguishes strictly between soundproofing and soundproofing. In the sound attenuation, the acoustic vibration energy in other forms of energy such. B. converted heat. In sound insulation, the passage of longitudinal vibrations (sound) is reduced by a barrier. This happens z. B. also by reflection of the sound. Preferably, the structural adhesive is adapted to the expected application and can either sound-absorbing or sound-damping effect or even have both properties at the same time. In particular, the structural adhesive of this type is the use of a structural material as described in the international patent application PCT / EP2007 / 008141. For the aspects concerning the structural adhesive, reference may be made to the cited document, the disclosure content of which supplements the disclosure of the present patent application in this respect.

Another advantage is the use of a structural adhesive of a thermosetting structural material. This is preferably an expandable structural adhesive. Thus, by the cohesive second connection, in particular in the case of a suitable geometric arrangement of the components, it is also possible to connect regions which still have to remain accessible during the assembly process. When using a thermosetting structural adhesive, it is also advantageous that for curing the thermosetting structural material, the process heat from other process steps, especially in vehicle and / or body construction is used to connect the components cohesively with each other. The activation and / or expansion of the expansible material may preferably take place by utilizing the process heat of a cathodic immersion furnace to cure the cathodic dip painting, for example, a motor vehicle body. Of course, a separate effect of heat to expand the activatable and / or expandable material is conceivable.

Another advantage is the use of a multi-component structural adhesive. Preferably, the two components are mixed together in the mechanical first connection via a mechanical connection technique, which leads to an activation and setting of the structural adhesive and thus to the cohesive second connection of the components via a cohesive joining technique. Further process steps for activating the structural adhesive would not be necessary in this case. The use of a structural adhesive whose heat setting time is, for example, at room temperature in the range from 20 minutes to 90 minutes has proved to be particularly advantageous. This allows a correction of the position of the components to be connected to one another, for example, by the mechanical first connection is released. The final connection of the components by the cohesive second connection takes place only after the setting of the structural adhesive.

Another advantage is the use of a contact surface of the cohesive second connection, which provides the cohesive second connection between the components, which is at least as large as the contact surface of the mechanical first connection, which provides the mechanical first connection between the components. Preferably, the contact surface of the cohesive second connection coincides with the contact surface of the mechanical first connection. In particular, when using an adhesive for the cohesive second compound so an adhesive layer between the individual components to be connected can be provided. Thus, for example, a seal, insulation or damping can be provided. In addition, in particular a possibly necessary galvanic separation of the components to be connected can be ensured. This can be implemented in particular with the use of structural adhesives for the cohesive second compound. Here, for example, a non-conductive structural adhesive can be selected, which in particular can enable an isolation of the components to one another. It can also be ensured that an equally large or preferably larger contact surface of the cohesive second connection not only a punctual, but rather a surface connection of the components, so that, for example, forces acting on the components can be better transmitted. Another object of the present invention is a connecting means for connecting components in the vehicle or body construction comprising means for providing a mechanical first connection to the components and with a structural adhesive for providing a cohesive second connection of the components.

Another object of the present invention is a method for connecting components in the vehicle or body construction are provided in the first to be connected components. Subsequently, the components are connected by means of a connecting means via a mechanical first connection by means of a mechanical connection technique. Subsequently, the components are joined by means of the bonding agent, which is equipped with a structural adhesive, via a cohesive joining technique.

Some particularly preferred embodiments of the invention will now be explained in more detail with reference to the drawings.

The assemblies illustrated in the figures may in particular include components such as a battery carrier, a fender receptacle, an axle component, a bumper, a bonnet or a boot holder, a roof or a roof or a floor component or other attachments, which preferably with a second component , For example, a body, a space frame, a frame or parts of these mentioned components are connected.

FIG. 1 shows a sectional side view of an assembly 1 according to the invention. The assembly 1 consists of a first component 2, in the present case a battery carrier for accommodating a starter battery. As well as a second component 3, a region of a vehicle body in the engine compartment of the vehicle, to which the first component 2 is to be mounted. For mounting, the component 2, 3 have substantially circular openings 14, 15 with the same diameter, which are aligned with one another in the installation position of the components 2, 3 shown. Furthermore, the assembly 1 comprises a connecting means 4 designed as a bolt, which consists of a cylindrical portion whose diameter is slightly smaller than the diameter of the openings 14, 15. For mounting, the connecting means 4 in a mounting direction 11, in the direction of the components. 2 3 with the cylindrical portion in the openings 14, 15 moves. The connecting means 4 also has a head portion 12, which may also be circular, but has a larger diameter than the cylindrical portion. Consequently, the connecting means 4 is in the inserted with the cylindrical portion in the openings 14, 15 with the state of the cylindrical portion radially projecting portion of the head portion 12, a support surface 13, on one of the components 2, 3, in the present embodiment, the first component. 2 , on. On the circumference of the cylindrical portion, the connecting means 4, a structural material 7. This is a thermally activatable and expandable structural material 7. In addition, the structural material 7 is provided on the first component 2 facing support surface 13 of the head part 12.

Figure 2 shows a sectional side view of the assembly of Figure 1 after the movement of the connecting means 4 in the mounting direction. The cylindrical portion of the connecting means 4 is provided in the illustrated embodiment in the openings 14, 15 and provides a connection, the first mechanical connection 9, between the components 2, 3 ready. In the present embodiment, the assembled connecting means 4 prevents at least one displacement of the two components 2, 3 against each other. On the components 2, 3 acting forces act mainly in the region of the openings 14, 15 on the connecting means 4. However, a small load of the connecting means 4 can also in the region of the head part 12, in particular in the region of the transition from support surface 13 to the lateral surface of the cylindrical Section of the connecting means 4 are detected. Of course, this first mechanical connection 9 can also be designed such that the two components 2, 3 are permanently connected to each other. Between the cy- The cylindrical portion of the connecting means 4 and the openings 14, 15 limiting side walls of the components 2, 3, the structural material 7 is provided. In addition, the structural material 7 is located between the support surface 13 of the head part 12 and the surface of the first component 2. In this way, in particular a direct contact of the connecting means 4 with the surface of the components 2, 3 can be avoided. This can be useful in particular for a seal or prevent, for example, contact corrosion between the components 2, 3 and the connecting means 4.

FIG. 3 shows a sectional side view of the assembly 1 from FIG. 1 with an activated and expanded structural material 8, for example, utilizing the process heat of a cathodic immersion furnace to cure the cathodic dip painting of the vehicle body. The expanded structural material 8 provides a cohesive connection 10 between the connecting means 4 and the components 2, 3 and thus a cohesive second connection 10 of the components 2, 3 with each other. In addition, the expanded material 8 fills the gaps between the connecting means 4 and the side walls of the components 2, 3 delimiting the openings 14, 15 and between the support surface 13 of the head part 12 and the surface of the first component 2. Due to the expansion of the structural material 8 is also accompanied by a frictional connection with the cohesive second connection 10. The friction between the connected components is increased by the expansion and results in an adhesive force. The structural material 8 thus generates in the present exemplary embodiment a combined non-positive and cohesive second connection 10.

As mentioned above act on the components 2, 3 acting forces in the present embodiment substantially in the region of the openings 14, 15 on the connecting means 4 a. However, a slight load of the connecting means 4 can also in the region of the head part 12, in particular in the region of the transition from support surface 13 to the lateral surface of the cylindrical portion of the connecting means 4. By equipping the head part 12 on the support surface 13 with the structural material 8 is also a großflächigere Distribution of forces acting on the head part 4 forces achieved. In particular, voltage peaks can be better distributed and loads reduced.

In addition, in particular with a suitable selection of the structural material 8, a sealing and / or insulation and / or a damping of the assembly 1 can be achieved. In the present case, the contact surface of the cohesive second connection of the components 2, 3 corresponds at least to the contact surface of the mechanical first connection of the components 2, 3. Both contact surfaces coincide. In addition, it may preferably come to an overlap of the contact surface of the mechanical first connection through the contact surface of the cohesive second connection 10. Thus, when selecting a suitable, for example, insulating structural material 8, in particular a possibly ne necessary galvanic separation between the connecting means 4 and the components 2, 3 are ensured. By using an additional insulation layer, not shown, between the components 2, 3 or insulation coating of one of the two components 2, 3, complete galvanic separation of the components 2, 3 can be made possible.

This combination of mechanical connection of the components 2, 3 and cohesive connection 10 brings great advantages. The mechanical connection provides in the present embodiment, a mounting fixation of the components 2, 3 ready. The position of the component 2, the battery carrier, is fixed via the mechanical connection via the connecting means 4 relative to the second component 3, the vehicle body, so that further assembly steps for producing the vehicle can take place. Also, a disassembly of the module can be done, for example, to reposition the first component 2 on the second component 3.

The final attachment and fixation of the first component 2, the battery carrier with the second component 3, the body takes place only by the activation and expansion of the structural material 8, whereby the cohesive second connection 10 of the components 2, 3 is provided. In this case, a thermal structural material 8 has been selected, the properties of which is set in particular with regard to the activation to the stoving temperature of the paint of the vehicle body. Thus, the activation of the structural material 8 during an already carried out process step, the stoving of the paint, take place, which saves time and costs.

FIG. 4 shows a sectional side view of an alternative of an assembly 1 according to the invention with two essentially cylindrical components 2, 3 to be connected before assembly. In the present embodiment, no connection means in the form of a separate component is needed. To the first component 2, a tapered first connecting member 5 is formed. To the second component 3, in turn, a corresponding to the first link 5, an inner cone exhibiting second link 6 is formed. Furthermore, a multi-component structural material 16 with a first component 17 and a second component 18 is provided on the first connecting member 5 in circumferential fashion. By a movement of the first component 2 with the first mounting member 5 first in the mounting direction 11 in the direction of the second mounting member 6 of the second component 3, a first connection, the mechanical connection between the components 2, 3 are made possible. This mechanical connection is made via the two connecting members 5, 6 depending on the requirement, in particular by means of a frictional connection by wedging or clamping or a positive connection similar to a tongue and groove connection. When merging the connecting members 5, 6, the multi-component structural member provided on the first connecting member 5 is material 16 is mixed by the second component 18 is pressed by the inner cone of the second connecting portion 6 bounding wall of the second component 3 in the direction of the first component 17. By mixing the components 17, 18, an activation of the structural material 16 takes place, which leads to a second connection, a cohesive connection, of the two components 2, 3 via their connection regions 5, 6. By suitable selection of the structural material 17, in particular a positional correction of the components 2, 3 can take place relative to one another. In this case, curing or setting times of the structural material of preferably in about one hour are conceivable.

FIG. 5 shows a sectional side view of a further alternative of an assembly 1 according to the invention with two components 2, 3 to be connected and one connection means 4. The components 2, 3 consist of a solid metallic square material and have at their opposite end regions one in each case in the direction of the components 2, 3 tapered inner gap on. Between the components 2, 3 is provided as a connecting means 4, a connecting element which has corresponding to the inner columns outer column and provides a mechanical connection 9 between the components 2, 3 via a force or positive connection between the gap areas. In addition, a structural material 8 is provided on the outer gaps of the connecting means 4, which is activated in the illustrated embodiment and which provides a cohesive second connection 10 of the components 2, 3 via the connecting means 4.

6 shows a sectional side view of a further alternative of an assembly 1 according to the invention with two components 2, 3 to be joined. Here, too, the two hollow cylindrical components 2, 3 have an inner or outer cone as mutually corresponding connecting members 5, 6, through which a mechanical connection 9 between the components 2, 3 can be provided. Between the connecting members 5, 6 an activated structural material 8 is provided, which provides a material connection 10 between the components 2, 3. This cohesive connection 10 is used in addition to the connection of the components 2, 3 in the present embodiment, in particular the sealing of the hollow cylindrical components 2, 3, so that the components 2, 3, for example, as operating lines, in particular for supply of fuel, oil, air or coolant for the vehicle can be used.

FIG. 7 shows a sectional side view of a further alternative of an assembly 1 according to the invention with two components 2, 3 to be connected. In the exemplary embodiment shown, a first connection 9 of mechanical type is provided by means of a dovetail connection. For this purpose, a first connecting element 5 formed as trapezoidal spring or prongs is formed on the first component 2. On the second component 3, there is again an integrally formed second connecting member 6, which corresponds to the first connecting member 5, in the form of a trapezoidal shape Groove into which the first link 5 engages. With such a mechanical first connection 9 not only lateral forces between the components 2, 3 can be transmitted, but also tensile forces. In addition, a structural material 8 is provided either on one of the connecting links 5, 6, which in the exemplary embodiment shown is in the activated state and provides a cohesive second connection 10 between the components 2, 3.

8 shows a sectional side view of a further alternative of an assembly 1 according to the invention with two components 2, 3 to be connected. In the present exemplary embodiment, the two components 2, 3 are of hollow cylindrical design and are used, for example, as pipelines for the coolant circuit of a vehicle. In order to achieve a constant pressure and volume flow within the pipes, a constant diameter of the pipes is advantageous. For this purpose, the second structural element configured as a straddle tube 3 has a widened connecting member 6, wherein the inner diameter of the connecting member 6 is greater than the outer diameter of the first component 2. The first component 2 is pushed for assembly with a connecting member 5 in the direction of the second component 3 until the connecting member 5 is in the expanded connecting member 6 as in the embodiment shown. By pushing together the two connecting members 5, 6, a mechanical first connection 9 of a positive type between the components 2, 3 can be provided. Between the connecting members 5, 6, an activated structural material 8 is provided, which provides a cohesive second connection 10 between the components 2, 3. This cohesive connection 10 serves in addition to the connection of the components 2, 3 in the present embodiment, in particular the sealing of the hollow cylindrical components 2, 3. Before assembly, the non-activated structural material on the inner wall of the widened connecting member 6 is provided. The unactivated structural material is highly viscous and sticky in this state. When pushing together of the two components 2, 3 and the introduction of the connecting member 5 in the widened connecting member 6, a non-positive connection between the components 2, 3 is provided by the non-activated structural material by its highly viscous and sticky properties in addition to the mechanical first connection 9 positive manner ,

Of course, materials with other shapes and properties can also be used for the cohesive second connection 10. For example, as such, a particularly thin band, preferably non-adhesive in the non-activated state, can be wound around the connecting member 5 of the first component 2. Subsequently, the first component 2 is pushed for mounting with the connecting member 5 in the direction of the second component 3 until the connecting member 5 is in the expanded connecting member 6 as in the embodiment shown. After thermal curing, harden tet the band wound around the connecting member 5 and optionally expand and provide the cohesive second connection 10 between the components 2, 3.

9 shows a sectional side view of a further alternative of an assembly 1 according to the invention with two components 2, 3 to be connected and a connecting element 4. The components 2, 3 have openings, each with an internal thread 20. The connecting means 4 is equipped with a corresponding to the internal threads 20 external thread 19. For a mechanical connection 9 of the two components 2, 3, the external thread 19 of the connecting means 4 is brought into engagement with the internal threads 20 of the components 2, 3 by the connecting means 4 being rotated relative to the components 2, 3. In addition, a structural material 8 is provided on the external thread 20, which is in the shown embodiment in the activated state. The structural material 8 comes in mechanical connection with the internal thread 20 of the components 2, 3 in contact and after activation, for example by the influence of heat when using a thermally activatable structure material 8, a cohesive connection 10 both between the connecting means 4 and the components 2, 3 and thus between the components 2, 3 via the connecting means 4 ready.
