Description

The 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 assembled components are in many Areas of a vehicle or a body and are the state the technique known several times.

The Standard joining technique for metals especially in the Vehicle construction is welding. Disadvantages with this Procedures are associated in particular when connecting various metallic materials such as in the Connection of components made of steel with components made of aluminum or magnesium. The usual method is spot welding. However, it requires certain geometrical conditions around the To apply welding tools. In addition, will only a selective power transmission between the decreed Sharing allows. Another technique used is the laser welding, which is a flat Connection allows. The required application technology However, it is expensive and prone to failure. A large Disadvantage of all welding processes, however, is the negative Influencing the surface quality by flying sparks and distortion and impairment of material behavior in the heat affected zone.

In addition, mechanical connection techniques are also used in vehicle construction. For example, such an assembly of the US4,936,409A known. 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 connections are used to form a full-surface Power transmission between the parts manufacture. The setting time of the adhesives is always one Compromise between pumpability and applicability and the required Ersthaftung necessary for the further assembly process is. Structural adhesives predominantly reach their full joining force in vehicle construction when curing in the paint oven. However, to those for whom Assembly process necessary, mechanical strength of the body usually need welding points are set, which in turn are listed above disadvantages entail.

Therefore It is the object of the following invention, an improved joining technique to provide for the vehicle, the aforementioned disadvantages eliminated.

These Invention is solved by the features of claim 1.

advantageous Embodiments of the invention are defined by the subclaims specified.

basic idea The invention is the use of an assembly of joined Components in vehicle or body construction with connecting means for connecting the components, wherein a first connection of the components is provided by a mechanical connection technique and wherein a second connection of the components by means of a cohesive Joining technology is provided.

Preferably is the connecting means with means for providing the mechanical Connection equipped. It can act as a connecting means both individual or single connection suitable for a connection multiple Verbindungsbereiche- or members of the components used come as well as separate components, such as fasteners known in the art, in particular bolts, screws, springs, feather keys, wedges, rivets or pens. When using a connecting element as a connecting means In particular, components made of a plastic such as, for example, are suitable Polyamide, in particular with other fillers or as Composite material designed. Also conceivable is the use of a Such a connecting element made of a metallic material, such as steel, especially a high strength steel. One Such connecting element can, for example, as a connector be used for connecting components.

When mechanical first connection is between the components or between the components and the connecting means is in particular a non-positive connection conceivable. Of course is the mechanical first connection also by means of a form-fitting Connectible. Thus, in particular, a snap connections, a tongue and groove connection or bung, a dovetail connection or a feather key or other known in the art Connection types are 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 as a separate components configured connecting elements at least area be equipped with an adhesive. By using a suitable adhesive for the cohesive second connection also an optionally necessary galvanic separation of the components of the assembly can be ensured. Also, for example, for the cohesive second compound, an adhesive can be used, which is able to connect, for example, components of different materials.

When components to be connected can be used in particular in vehicle and body construction to be mounted components are used. So For example, a component can represent the body and another component, for example a battery carrier, a cooler or components, in particular pipes of the cooling system, an engine mount, a fender mount, an axle component, a bumper, bonnet or trunk holder or another attachment, which are connected to the body should represent. Also, such an assembly components a space frame, as well as a roof or roof or floor components, that with a further component, in particular a body to be connected.

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

By Use of a combined mechanical and cohesive Connection or joining can have more advantages be achieved. For example, the first connection can be over a mechanical connection technique for fixing the position of the connecting components of the assembly used relative to each other become. The second connection via a cohesive However, joining technology is only the final Attachment between the components. Another advantage is the possibility of providing an immediate Connection force over the mechanical connection, which for example, may be required for the assembly process in combination with the material connection, which can be configured in particular flat and, for example only in a later process step.

According to one advantageous development of the invention, it is therefore provided that the cohesive second connection of the components takes place after the mechanical first connection of the components, around by the mechanical first connection a temporary To provide mounting connection and the cohesive second connection a final connection of the components to achieve the assembly.

One Another advantage is the use of a structural adhesive for the cohesive second connection by means of the cohesive Joining technology. Optionally, the structural adhesive can be mixed with expandable materials to achieve a wider setting area. Also can by the use of such a structural adhesive any in the manufacture of the components and / or the connecting means compensated component tolerances in the addition compensated become. Through the use of adhesives, in particular a achieved surface bonding of the components to be joined become. There is also a choice of a suitable adhesive in the Contrary to the usual in vehicle and body shop Welding process no negative influence on the surface quality and no heat affected zone with impairment of the material behavior in selbiger.

Preferably come here structural adhesives used, which among the Conditions of assembly process of the assembly, for example the mechanical first connection, not yet set, but only later, for example, by the action of temperature or others Cure energy forms and the cohesive provide second connection between the components. For this can the structural adhesive, for example, before or during Assembly process applied to the mechanical fasteners and be installed.

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-hindering acrylate-containing adhesives. It is also possible to use temperature-stable polyimide adhesives. The adhesives should be temperature and solvent stable 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. Anaerobic curing adhesives are understood to include 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 initiated under anaerobic conditions becomes. 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 present as a 2-component system or as a 1-component 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 may in particular be suitable polymers Base binders are used, such as ethylene-vinyl acetate copolymers (EVA), copolymers of ethylene with (meth) acrylate esters, optionally still proportionately contain (meth) acrylic acid in copolymerized form, random or block copolymers of styrene with butadiene or Isoprene or its hydrogenation products. The latter can also triblock copolymers of the type SBS, SIS or their hydrogenation products Be SEES or SEPS. In addition, the binders can still Crosslinkers, adhesion promoters, toughening resins ("tackifiers"), Plasticizers and other auxiliaries and additives such. B. low molecular weight Contain oligomers. To achieve a sufficient drivability and expandability contain these polymeric binders still propellant. Suitable blowing agents are in principle all known Propellant such. B. the "chemical blowing agents" the release gases by decomposition or "physical blowing agents", d. H. expanding hollow spheres. Examples of the former Propellants are azobisisobutyronitrile, azodicarbonamide, di-nitrosopentamethylenetetramine, 4,4'-oxybis (benzenesulfonic acid hydrazide), diphenylsulfone-3,3'-disulfohydrazide, Benzene-1,3-disulfohydrazide, p-toluenesulfonyl semicarbazide. Examples for the physical blowing agents are expandable plastic microbubbles based on polyvinylidene chloride copolymers or acrylonitrile / (meth) acrylate copolymers, as they are z. B. under the name "Dualite" or "Expancel" of the companies Pierce & Stevens or Casco Nobel are commercially available.

One 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 technique with a structural adhesive. In particular, threaded areas or other connection areas or members of such connecting means with the structural material be considered. The mechanical first connection of the components is in this case by the actual mechanical connection technology the connection means provided, for example by means of a Screw connection. The cohesive second compound takes place through the activation of the structural adhesive, for example by means of a heat through the paint-baking process of Body painting when using a thermally activated Structural material.

One Another advantage is the use of a structural adhesive for the cohesive second connection of the components, which in addition a non-positive connection provides. It is through the use of structural adhesive For example, already in the non-activated state of the structural adhesive a friction between the components to be joined, for example the components or the components via a separate Connection element provided. This friction can in particular lead to an adhesive force, so that by this non-positive Connection to the connected components tensile forces act can, by the adhesion of the non-positive Compensation can be compensated without the Connection triggers. By this way of providing a non-positive connection through the structural adhesive Thus, the mechanical first connection, for example a positive connection, especially before the Activation of the structural adhesive can be increased. there On the one hand, the choice of the adhesive can be relevant for the cohesive second compound is a structural adhesive, which is preferably provided on or at the connecting means is selected, which, for example, sticky and is tough and already unactivated in this way Condition the two components together positively combines. On the other hand, the structural adhesive provided with Contact surface for the cohesive second connection be relevant because the adhesion of the non-positive The larger, the larger the connection provided with structural adhesive contact surface. In addition is the use of an expanding adhesive conceivable, the alternative or additionally in the expansion to provide the cohesive second connection the friction between increases the components to be joined and thus a larger Adhesive force and a combined non-positive and non-positive provides 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 vibrations, which are often in the audible range of the human ear. These vibrations can take the form of Structure-borne noise propagated over the entire vehicle or the machine or the device and can be emitted at remote locations in the air as a 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 is described. For the aspects concerning the structural adhesive, reference may be made to the said document, the disclosure content of which supplements the disclosure of the present patent application in this respect.

One Another advantage is the use of a structural adhesive from a thermosetting structural material. Preferably this is an expandable structural adhesive. So can by the cohesive second connection, in particular with suitable geometric arrangement of the components also areas be connected, which remain accessible during the assembly process have to.

At the Use of a thermosetting structural adhesive It is also advantageous that the curing of the thermal hardening structural material the process heat from other process steps, in particular in vehicle and / or body construction is used to the components cohesively with each other connect to. The activation and / or expansion of the expandable Materials can preferably be made by utilizing the process heat a KTL furnace for curing the cathodic dip coating for example, a motor vehicle body done. Of course is also a separate effect of heat for expansion of the activatable and / or expandable material conceivable.

One Another advantage is the use of a multi-component structural adhesive. Preferably, the two components in the mechanical first connection via a mechanical connection technology mixed together, resulting in activation and ligation of the Structural adhesive and thus to the cohesive second compound of the components via a cohesive joining technique leads. Further process steps for activating the structural adhesive would not be necessary in this case. As a particularly advantageous has proven the use of a structural adhesive whose Setting time, for example, at room temperature in the range of 20 Minutes to 90 minutes. This allows a correction the position of the components to be connected to each other by, for example, 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.

One Another advantage is the use of a contact surface the cohesive second compound which the cohesive second connection between the components provides which is at least as large as the contact surface of the me chanical first connection, which is the mechanical first connection provides between the components. Preferably coincides the contact surface of the cohesive second Connection with the contact surface of the mechanical first Connection. Especially when using an adhesive for the cohesive second compound can thus be an adhesive layer provided between the individual components to be connected become. For example, a seal, an insulation or attenuation can be provided. In addition, in particular a possibly necessary galvanic separation of the be guaranteed to be connected components. This is especially in the use of structural adhesives for the cohesive second connection can be implemented. Here, for example a non-conductive structural adhesive can be selected, the in particular, allow an isolation of the components to each other can. Also can be guaranteed that by an equal size or preferably larger contact area the cohesive second compound not just a punctual, but rather a surface connection of the components takes place, so that, for example, acting on the components Forces can be transmitted better.
