    [0001] The present invention relates to a frame longitudinal beam structure for chassis frames for utility vehicles, especially trucks and / or buses, according to the preamble of claim 1. Furthermore, the invention relates to to a process for producing a longitudinal frame beam for a longitudinal frame beam structure according to the preamble of claim 23.
    [0002] Chassis for motor vehicles, especially chassis for utility vehicles, according to classification and function, can be framed in four essential groups of construction, which are chassis frame, driver's cabin, displacement mechanism and propulsion section. In this case, the frame of the chassis constitutes the central built group of support of the chassis, in which are assembled both groups constructed of the displacement mechanism as well as the body itself. The same is true for buses, provided that - as is usually the case today - they do not have a self-supporting structure.
    [0003] In the construction of utility vehicles commonly and especially for trucks, buses, and / or semi-trailers that receive their bodywork only in a later assembly step, using the so-called integral support chassis frames.
    [0004] The different frame designs are differentiated by the basic layout of the frame, that is, the arrangement of the support components, in convergent relation and the cross section of the profile, that is, the cross shape of the supporting elements. Conventional chassis frames are shaped like conductive frames that are either rigid and depending on the shape of the profile cuts or are soft to the torsion or rigid to the torsion. In the case of frames for soft torsion chassis, the longitudinal beams and crossbars consist of open profiles. Compared to open profiles, closed profiles, with approximately comparable main dimensions, are more rigid to torsion by a multiple factor. The choice of the appropriate profile will depend, first of all, on the purpose of using the vehicle, whether, for example, it should be used on rough terrain or on the highway, and also depending on the body's torsional rigidity, that is, the flexibility of the body. body fastening.
    [0005] In a very predominant way, frames for chassis and utility chassis are realized as conductors with soft twisting of longitudinal beams of C-shaped frame, that is, U-shaped (hereinafter referred to as C-shaped), representing longitudinal frame beams with fixed fillet as central fillet. In order for vertical forces to be induced by the body and the body consoles, that is, the displacement mechanism and the corresponding support racks on the chassis frame, close to the central push point, the longitudinal beams of the frame will normally be arranged with the opening facing inward. Among the chassis frames employed are known chassis frames that have or on straight longitudinal beam profiles, with continuous and constant cross section, that is, identical, or through curved profiles in horizontal or vertical direction, partially even having of profiles of various curvatures. The production of these longitudinal frame beams takes place regularly in special production sites, where the starting material is unrolled from a so-called coil, that is, a coil, and then cut into platinum shapes and drilled before receiving their final shape in the press, in a process of transformation, folding and flexing of the frame's longitudinal beams. The effort to produce conventional longitudinal frame beams is, therefore, always great and implies high costs and can only be made in special plants that have a large press of up to 50,000kN, or greater pressing force and that, in addition, they feature the most modern profiling facilities for the rolling process, that is, folding of the longitudinal beams.
    [0006] In addition to the traditional longitudinal frame beams which have upper and lower belts, as well as a vertical fillet that joins the two belts, that is, also in the form of a central fillet, they are known, for example, of document DE 10 2007 056 404 A1, longitudinal frame beams of a chassis frame that are formed by two rails that project in the longitudinal direction of the vehicle and that are interconnected in vertical direction by connection elements of variable conformation, that is, bent and curved differently. The two rails that, in this case, form the upper belt, that is, the upper belt of the longitudinal beam of the frame, are shaped like U, and the openings of the rails, vertically overlapping, are facing each other. In the openings, that is, in the region between the flanks of the rails, faces for fixation are provided, in which the connection elements of vertical projection are welded. Structuring this type is very complex from the point of view of production and finishing technique and requires a large number of the most diverse components that represent an enormous cost. In all, this is, therefore, a modular structure of the longitudinal beams of the frame, which is very expensive and, therefore, especially less practical.
    [0007] In addition, from US 2007/0194564 A1 a conductive frame for the vehicle trailer became known, in which the longitudinal beams of the frame are formed by basic profiles with a flattened central fillet in the form of a plate, covering the entire the extension of the longitudinal beam of the frame, and being straight and curved, in whose free opposite ends a flank element is applied or pressed which forms an open profile area in C shape on both sides of the central thread, in which the elements of transverse projection of the conductive frame are integrated and used. The connection of the applied profile elements is verified by a rivet connection.
    [0008] In addition, from document DE 10 2009 041 050 A1 a longitudinal frame beam of a motor vehicle became known, in which the upper belt and the lower belt are formed as a closed hollow profile, with both the upper belt as well as the lower belt, a fixation splint in the direction of the respective other belt is highlighted, this splint being used for the coupling of several connection elements, reciprocally spaced in the direction of the longitudinal beam of the frame. With a modular frame longitudinal beam structure, weight must be saved and, in addition, flexible adaptation of the frame's longitudinal beam structure to the most different types of motor vehicles must be possible.
    [0009] Furthermore, it is generally known to provide a so-called support mechanism divided as a chassis frame, in which in the front area of the vehicle, that is, where the groups are mounted and where the driver's cabin is located, the frame of the chassis always has a longitudinal beam on the left and right sides of the frame, which is shaped with a Z-profile cut. In this Z-profile cut, a longitudinal beam component of the frame follows behind, towards the rear of the frame. frame that has a conventional C shape as a profile cut. The C-shaped rear chassis section will be, in this case, with the Z-shaped front frame section, more complex, screwed, presenting a large number of screw connections.
    [00010] In view of the above, it is an objective of the present invention to provide a frame longitudinal beam structure for chassis frames for utility vehicles, especially trucks and / or buses that have a longitudinal support of modular construction frame and that allows adapt the chassis frame of the vehicle in a flexible way in the most different types of motor vehicles, allowing, in addition, a construction according to the flow of forces, with optimized profile cuts and, in addition, it offers a high potential for saving Weight. In addition, it is the task of the present invention to provide a process for producing a longitudinal frame beam, that is, a longitudinal frame beam, for chassis frames for utility vehicles, especially trucks and / or buses, the process being simple and at an advantageous cost from the technical point of view of construction.
    [00011] The solution of these tasks is carried out with the characteristics of the independent claims. Advantageous modalities are the subject of the dependent claims, which are remissive respectively.
    [00012] According to claim 1, it is proposed to build a longitudinal frame beam for chassis frames for utility vehicles, especially trucks and / or buses, which has at least one longitudinal frame beam, of modular construction, which in the assembled state it projects in the longitudinal direction of the vehicle, and the longitudinal beam of the frame has a base profile that essentially protrudes over the entire length of the longitudinal beam of the frame, presenting a central fillet that extends in the form of a plate and - observed of the cross section - it is located between opposite regions of the longitudinal beam of the frame, especially between a region of an upper belt and a lower belt of the longitudinal beam of the frame, being that the central thread - seen in the direction of the longitudinal projection of the base profile - essentially extends in a rectilinear manner and in this central thread are complementary profiles connected in a flat back connection, which are fo separated by separate building components. According to the invention, it is proposed that several complementary profiles, essentially rectilinear, extend in the central thread that essentially protrudes over the entire length of the longitudinal beam of the base profile which in the direction of the longitudinal beam projection are conformed to the at least two longitudinal beam areas of the frame with a longitudinal beam profile cut of varying frame.
    [00013] With a modular structure in this way, according to the invention, for example, on the basis of a single base profile, with a profile cut essentially, continuously constant or identical, a cross-sectional geometry that is suitable can be offered through the direction of the longitudinal beam beam projection, precisely to the respective load case, and which provides the respective required surface inertia moment, that is, the respective required torsional stiffness, in an optimal way, precisely where it is required by respective load situation, so that a longitudinal frame beam conformation, suitable for the dimensions, is made possible, avoiding excess dimensioning, providing the central thread and, in addition, a possibility of straight and spatial coupling for the complementary profiles. This means that, for example, starting from a base profile with a defined cross section and with an equally defined wall thickness, the complementary profiles can be arranged and assembled in such a way that they present, for example, compared with the base profile, different thicknesses of material, ie, wall and / or being formed from another material, for example, a light metal, in order to save weight. In addition, with a modular concept, according to the invention and of this kind, from the base profile and from different complementary profiles, longitudinal frame beam structures can be produced, in which - for example, with reference to identical areas of longitudinal beams of the frame - in different types of vehicles, varied cross profiles can be realized in a simple way, especially also because the complementary profiles can be arranged - with respect to different types of vehicles, for example, at different heights in the vertical direction - thus being able to be positioned, being that, for example, the cross section of the profile, specifically, for example, a cross section of Z profile in the others is preserved.
    [00014] Furthermore, it can be ensured with the solution recommended by the present invention that the longitudinal beams of the frame can be produced with a lower overall wall thickness, that is, of material than this occurs in the longitudinal beam structures of conventional frames , curved and folded, in which a wall thickness is maintained, from the front to the rear, resulting in certain regions in considerable oversizing. The thinner wall thicknesses that are possible according to the invention furthermore have the advantage that with thinner wall thicknesses of this type, smaller bending radii can also be provided, for example, in connection with the folding process such as, for example, the action of rolling, folding or laminating to form the flanks of the profiles of the different building components, with which shorter lengths of the profiled flanks can be obtained and it is feasible to realize, in this way, correspondingly, greater vertical lengths in the region of the central thread, which is advantageous, for example, for the support connection in a large area of the complementary profiles, bringing more constructive free space, in relation to the fixing of construction components. In addition, the manufacture of the components of the frame's longitudinal beams, from the technical point of view of production, can also be used in rolling mills with less technical equipment, so that this way the production and finishing effort can be considerably reduced.
    [00015] Therefore, it should be expressly mentioned that the central fillet, that is, the base profile preferably presents a profiled section, continuously constant or identical, basically in the longitudinal direction, in order to make available in the coupling regions of the complementary profiles, a possibility of spatial coupling, precisely for the complementary profiles, but the base profile, that is, especially the central fillet, naturally can also have reinforcements in the form of grooves, projections, etc., as well as cutouts, duplication of material and / or holes , screws, etc., if necessary. This will then naturally take place preferably outside the coupling areas of the complementary profiles and is not in contradiction to the basic idea of the invention, according to which a base profile serves as a starting point, so that - referred to the most different types of utility vehicles and / or referred to the most different cases of employment, that is, of use - seen on the direction of the longitudinal beam projection of the frame, to make cuts of profile of longitudinal beam of the frame, precisely optimized for the respective case of employment, considering that the base profile can be combined with a defined and applied transversal profile geometry, resulting in complementary profiles in the technical area of production and finishing.
    [00016] In this case, a concrete modality is particularly preferred, in which at least the central thread of the base profile extends in the direction of the longitudinal beam of the frame, without a curvature (free from curvature), seen in the direction of the elevated axis of the longitudinal beam of the frame and / or conformed to a fold (without folding, that is, free from folding) in a transversal direction towards the longitudinal direction of the frame. It is preferred from the technical point of view of finishing especially that the base profile as a whole is formed as a simple profiled component, without curvature and / or without curvature and, therefore, projecting in a straight direction towards the longitudinal beam of the frame. In this way, the longitudinal beams of the frame as a whole can be produced simply, without a complex bending and folding action, because the complementary profiles can be selected in such a way that the desired longitudinal frame beam areas can be shaped. in certain diverse regions, also without the application of a curvature or folding process of the basic profiles. As already mentioned above, in this process it is understood with the expression to bend a bend or chamfer in the elevated direction of the axis, while with the bend it is understood to bend or chamfer in a transversal direction towards the longitudinal direction of the frame.
    [00017] Especially preferred, as at least the central fillet of the base profile, preferably the entire base profile has a profile cross section - seen in the longitudinal direction - basically the same continuously, but this does not exclude - as already mentioned - that the central thread, preferably outside the coupling area of the complementary profiles, at certain points, has at least one reinforcement such as a groove and / or protrusion and / or at least a cutout.
    [00018] The base profile, preferably that extends essentially over the entire length of the longitudinal beam of the frame, of straight projection and without curvature, will preferably be one piece, especially of the same material and / or one piece, because in this way it can be reduced considerably the effort applied to the construction component and, therefore, also the effort of the production itself.
    [00019] As already indicated, these complementary profiles can be attached differently to the base profile. For example, complementary profiles can be fixed flattened on the same side, seen in a transversal direction towards the direction of the longitudinal beam of the frame, or on different sides of the central thread of the base profile. Alternatively or additionally, complementary profiles can be coupled at different heights in the central thread of the base profile, in a spatial connection. In addition, complementary profiles can be coupled, in an alternative or additional character, referring to the direction of the longitudinal projection of the complementary profile and the direction of the longitudinal direction of the base profile, at a defined and reciprocally out of angle, in a spatial connection in the central thread of the base profile, so that, for example, with straight profile components, form a region of longitudinal frame beam that corresponds to a region of longitudinal frame beam, produced in a conventional manner by forming curvatures and / or bending.
    [00020] It is understood that the complementary profiles present only a longitudinal projection in the direction of the longitudinal beam of the frame, as this is necessary for the formation of a desired profile cut in the respective area of the longitudinal beam of the frame, so that the profiles Complementary items should normally be made shorter than the base profile allocated to them. The spatial support connection in this case represents a particularly stable coupling that makes it possible to induce the force, without undesired force peaks in the respective area of the frame's longitudinal beam.
    [00021] According to an especially preferred modality, with respect to the concrete conformation of the complementary profiles, it is proposed that profiled flanks of the complementary profiles, connected in the central thread of the base profile, are formed without curvature, in the direction of elevated axis and / or without bending , in a transversal direction towards the direction of the longitudinal beam of the frame, being preferably all the complementary profile formed as a profiled component without curvature and / or without bending and, therefore, of rectilinear projection. In this way it is possible - as already explained in relation to the base profile - again to considerably reduce the technical effort of production and by the adequate conformation and selection of the complementary profiles, even so any longitudinal beam cross section of the desired frame can be realized at the same time. along the longitudinal beam of the frame and this - as already mentioned previously - in a different way along the longitudinal beam of the frame.
    [00022] Here again, it can be concretely provided that at least the profile flank of the respective complementary profile, preferably the complementary profile as a whole, coupled to the central thread of the base profile, presents a profile cross section of preference, basically covering the entire complementation profile, seen in the direction of longitudinal projection, but this does not exclude, as mentioned before, that the complementary profile preferably has outside the coupling region, in the central thread of the base profile and at defined points, at least one reinforcement shaped like a bandage and / or protrusion and / or having at least one cutout.
    [00023] According to a concrete modality, especially preferred, it is proposed that the base profile has a profile cross section, with at least one profile flank that projects in an angular direction - at least in areas, from the central fillet which, through the complementary profiles, can be complemented for a profile cross section that includes Z or C format, or a profiled cut. Especially preferred in this case is a structure, in which the base profile - at least in an area of the longitudinal beam frame, front or rear - is complemented with at least one complementary profile, especially with a single complementary profile, making up a section cross-sectional profile that includes the Z shape and / or in which the base profile is complemented at least in a region of the front or rear longitudinal beam, relative to the direction of travel, with at least one complementary profile, especially a single complementary profile, with a longitudinal beam of profile section frame that includes or presents the C shape, preferably in a state mounted on profiled flanks that in the direction of transverse displacement project inwards. In this way, a structure of the longitudinal beam of the frame is made available which, in connection with utility vehicles, especially trucks and here especially heavy trucks, is optimally shaped and advantageous in relation to the layout of the driver's cab, displacement mechanism and drive section , that is, from the body itself and, for example, in the front region it offers a construction geometry, and, for example, in the front region it offers a fish belly shape geometry, without folding or curving a longitudinal beam of the frame , that is, the base profile and / or the complementary profiles, while, for example, the rear area may have the conventional C shape with profile flanks designed inwards, in the form of upper and lower belts.
    [00024] The expression "comprehensive profile cut" means that, for example, in connection with a profiled cut that includes, for example, the C shape, the expression can also cover cross-section geometries that, for example, have a shape And, since this format E also includes a C format. The analog is valid for all other cross sections of profiles expressed with the word "include".
    [00025] This means, in other words, that the base profile can have a cross-section of profile basically random, for example, a cross-section of profile in the form of L or C or E or even in the form of T, while , for example, the complementary profiles have a cross section with the same or different profile - referred to the complementary profiles and / or the base profile - and / or they can present a cross section of an L or C or E profile. example, that the base profile in the cross section in the form of C or E is complemented in a region of longitudinal beam in the direction of travel, with at least one complementary profile, constituting a profile cut that includes or presents a Z shape. Alternatively , it could be predicted in this sense that the base profile in the T-shaped cross section is complemented in a longitudinal beam region of the front frame in the direction of displacement, with at least one comp profile element, composing a longitudinal beam region of the rear frame, with reference to the direction of displacement, with at least one complementary profile, composing a profile cross section that includes or presents the C shape. In this case, however, they result especially in connection with profile flanks, not required at the respective point of the longitudinal beam of the frame, longitudinal beam structures of the frame that produce a job of material eventually increased, which can have negative effects in view of the costs.
    [00026] In this sense, according to an especially preferred and concrete solution of the invention, it is envisaged that the base profile will have an L-shaped cut, as this way - especially in connection with a complementary profile that, for example, also it presents an L-shaped cross section, the desired and necessary L, Z or C-shaped profile cuts - can be formed at the most different points of the longitudinal beam, in the direction of the projection of this longitudinal beam. In addition, the profile flank that protrudes from the central thread already shows, according to the position of its assembly, at least a partial area of the upper belt and / or lower belt, normally provided. A concrete construction is particularly preferred, in which the base profile for the complementary profile has an L-shaped cross section, since in this sense basically identical components can be used.
    [00027] According to another especially preferred modality, it is foreseen that the complementary profiles overlap, at least in certain regions, reciprocally in a region of central longitudinal beam frame, located in the region of the longitudinal beam of rear frame, seen in the direction of the longitudinal frame beam, this superposition being at least in certain areas, preferably overlapping on opposite sides of the central thread, at least in certain areas. A superposition of this species in the longitudinal direction of the support in the longitudinal beam of the frame allows a smooth transition regarding the resistance of the longitudinal beam of the frame, in this region.
    [00028] In this context, it is also particularly advantageous that the complementary profiles, coupled on opposite sides of the central thread, overtake this central thread - seen in the direction of a high axis - in an upward or downward direction, in such a way that in the area of the overlapping of the complementary profiles , these complementary profiles are always adjacent with one of their profile flanks, in a spatial connection and / or the other sides of the complementary profiles point in the opposite direction of the central thread. By the spatial arrangement of the complementary profiles that go beyond the base profile in the overlapping region, a particularly stable connection of the complementary profiles in the base profile is ensured in a simple way, so that in this region the longitudinal beam of the frame in this region is shaped optimized under from a technical point of view of energy flow, presenting high values of resistance and inertia that are especially advantageous when the region of the superposition is located in a requested region with special intensity of the chassis frame, that is, of the longitudinal beam structure of the chassis frame of the vehicle. It is understood that the complementary profiles, located on opposite sides, can be arranged both at approximately the same height, to conform, for example, in connection with a cross section of L profile, of the complementary profiles, in this region of overlap, a profile Upper T. In the same way, the complementary profiles - also in view of the flanks of the protruding profiles of the central fillet - can be arranged at different heights, with reference to the vertical direction, so that a staggered arrangement of the complementary profiles in the overlapping region results. As already explained above, this depends on the respective employment and use cases, that is, the respective load cases. The versions presented above demonstrate again that the system according to the invention provides a modular coffin for the formation of a longitudinal support beam structure, individually optimized for the respective use case, so that the production and finishing costs with this optimized conformation of the respective longitudinal frame beam construction faces can be reduced in a simple way.
    [00029] In connection with the structure of the longitudinal frame beams that has just been described in the region of the overlap, it is also advantageous that at least one of the complementary profiles, in the region of the profile flank that exceeds the central thread in the transition region, having an angle and / or curvature such that the region of the profiled flank that extends beyond the central fillet is out of phase on a defined lag path, especially in less than a portion of the thickness of the central fillet wall, in front of the region of the profiled flank, connected to the central thread, towards the profiled flank area of the other allocated complementary profile. In this way, in a simple way, the spatial coupling of the two complementary profiles can be ensured in the region of the superposition, as well as in the area that exceeds, in the direction of a high axis, the central thread.
    [00030] For example, the complementary profiles can be basically joined with the base profile, in a conventional way, with closure due to shape or force, for example, at least through a screw connection and / or rivets. According to an especially advantageous aspect of the present invention idea, the complementary profiles, however, should be joined with the base profile, with closure due to the shape and especially through an adhesive connection. In this context, it would be especially advantageous if the components constructed to be interconnected are coupled by means of a spatial adhesive connection, preferably by means of a glue connection, that is, an adhesive that joins the entire region of the back and the connection of the components to be interconnected with a defined adhesive layer thickness, filling a defined gap between the construction components to be interconnected. The gap distance can, for example, be ensured by spacer elements, such as balls integrated in the glue or cams, etc., pressed within the connection area. In this way, there are a number of advantages:
    [00031] Therefore, the adhesive connection, in the same way as a connection with closure due to force, for example, a screwed or riveted connection, can ensure a highly firm construction component fixing and meeting the respective requirements, and through the thickness of the adhesive layer, that is, glue, can also be influenced by the specific frequency and elasticity of the frame. In addition, by using the adhesive material technique, considerable weight energy can be achieved, because a large number of couplings by screws and / or rivets, which really contribute considerably to the high weight of the frame structures can be saved. In particular, there is an advantage here that even in the case of a combined closure connection due to the shape and / or strength with an adhesive connection, it continues as before, it is possible to save a series of screw connections, that is, riveted. The use of the adhesive connection also allows, in a simple way, a mixture of material, because the adhesive layer keeps the construction components at a distance, normally incidents of corrosion, so that. For example, conventional steel materials, for example, in the region of the base profile, can be combined in a simple way with light metal material of the complementary profiles, without the possibility of contact corrosion.
    [00032] Another special advantage of gluing must be seen in the fact that through gluing the connection points can be very tightly sealed, which is also of great importance with regard to protection against corrosion.
    [00033] Another essential advantage of the solution according to the present invention can be seen in the fact that in the use of the bonding technique, moreover, the hardening of the bonded connection in the context of the coating to be provided in any way of the longitudinal beam of the frame, a KTL coating can be specially made (KTL = cataphoresic immersion lacquer).
    [00034] Preferably the glue will be applied in the form of liquid glue, but basically it could also be formed by an adhesive tape.
    [00035] According to an aspect of the invention in this sense, especially advantageous, it is proposed that the building components to be interconnected are joined before the adherent connection hardens, producing a closed connection due to shape and / or force, especially with a connection screwed. Basically, this connection could also be removed again after hardening. It is especially advantageous, however, when the construction component is pre-fixed, until the adherent connection has hardened, a connection with closure is fixed due to the at least viable force, while at the same time, at least one assembly component and / or a group will be fixed in the longitudinal beam of the frame or in the structure of the longitudinal beam of the frame. In this way, a particularly advantageous functional integration can be achieved, because the connection elements that will have to be provided in any way for the assembly components can be made simultaneously as fixing points, that is, reference points for the exact relative positioning of the building components to be interconnected through the adhesive connection. These additional connections with closure due to force produce, in this case, a reinforcement of the adherent connection, in a way that result in particularly highly resistant and secure couplings between the different construction components.
    [00036] Seen basically, it makes possible, therefore, the solution recommended by the present invention, in general, the use of light construction and the gluing technique, in connection with longitudinal beam structures of utility vehicle frames, which brings the numerous advantages already described above with respect to weights, costs, energy costs, etc., enabling a simple individual adaptation of the respective geometries of the longitudinal beam to the respective use cases, starting from an identical base profile.
    [00037] In this way, with the solution of the present invention, both in the base profile as well as in the complementary profile, that is, in the complementary profiles, very reduced material thicknesses, below 12mm, and especially below 10mm, can be achieved by example, wall thicknesses from 3 to 5mm, especially 8mm, in the case of vehicles, 10mm, that is, 12mm and in the lightest vehicles, 7mm.
    [00038] The solution recommended by the present invention also makes it possible - if this is necessary for the respective employment cases, that is, load cases - that the base profile and / or the complementary profiles are reinforced in defined areas, especially in defined areas of the profile flanks that protrude from the central fillet region, with at least one reinforcement element, especially in the sense of a duplication of material. This can be done, for example, by at least one separate building component, as a reinforcing element, for example, a building component in strip and / or plate format or also profiled in L shape, which is joined with the base profile and / or with the respective complementary profile allocated, with closure due to force, by means of a screw coupling and / or rivets, and / or through a glue coupling. Alternatively, in this sense, the reinforcement element may also be formed by a folding and / or edging of a profiled edge free region of a profiled edge of the base profile and / or at least one complementary profile. In the same way, the reinforcement can also be formed integrally in the respective profile-building component, for example, by a corresponding lamination of the respective profile-building component with variable wall thicknesses, for example, in the direction of a building component, smooth conformed.
    [00039] Regarding the process, the task will also be solved by the characteristics of claim 23.
    [00040] According to claim 23, a process is proposed to produce a longitudinal frame beam structure, with a longitudinal frame beam that, at least in assembled state, projects in the longitudinal direction of the vehicle, being of modular construction , and said longitudinal beam of the frame has a base profile, preferably a base profile that extends the entire length of the longitudinal beam of the frame, to which at least one complementary profile, formed by a separate construction component, will be connected. a form of spatial coupling. According to the invention, at least one complementary profile will be joined with the base profile by means of a glue connection and additionally by at least one connection with closure due to the strength and / or shape, especially through at least one connection by rivets and / or screws, and the construction components to be interconnected, by means of at least one connection with closure due to the strength and / or shape, until the adhesive connection hardens, will be aligned and / or pre-fixed precisely in position.
    [00041] The advantages that result from the execution of the process according to the invention, have already been explained in connection with the structure of the longitudinal beam of the frame, so that in this sense reference is made to the modalities presented above.
    [00042] As already explained, the hardening, that is, the hardening of the bonding connection is also performed here preferably in the context of an electrochemical coating process, especially a KTL lacquering of the longitudinal beam of the frame.
    [00043] According to another preferred modality, it is predicted that by means of the connection that enables the prefixing of the construction and / or alignment component, at least one connection with closure due to the force and / or shape, simultaneously, will also be fixed at least a building component and / or a group, in the longitudinal beam of the frame or in the structure of the longitudinal beam of the frame. The resulting advantages have also been mentioned above.
    [00044] The components to be joined will be coupled by means of a spatial adhesive connection, preferably through a region of the entire installation and connection of the components to be interconnected, with the application of an adhesive layer of defined thickness and / or with a space between columns of the components to be interconnected, as has also been explained before.
    [00045] Furthermore, according to an especially preferred sequencing, it is envisaged that several complementary profiles - according to the aspect of the invention already widely mentioned in the context of structuring the longitudinal beam - are so connected in a central fillet of a base profile, especially between a region of the upper belt and a region of the lower belt of the longitudinal beam of the frame, which in the direction of the projection of the longitudinal beam are formed at least two areas of longitudinal beam of frames with a section translation of profile of the longitudinal beam varied picture. Regarding the resulting advantages, reference will be made again to the explanations previously made.
    [00046] Furthermore, in claim 27 a longitudinal frame beam is claimed which is produced by a process according to the invention.
    [00047] The invention will be explained based on a drawing.
    [00048] The figures show: Figure 1 schematically a presentation only in principle and top view of a longitudinal beam structure supporting a frame for a chassis frame of a utility vehicle, for example a truck or a bus, Figure 5 a up to 2c schematic cross-sectional views along line AA, BB and CC in figure 1, figure 2d exemplified alternative conformation of the longitudinal frame beam region of figure 2a, figure 6 schematically a perspective overview of a longitudinal frame beam Figure 7 to up to 4b varied layout possibilities, shown schematically, of a complementary L-shaped profile in a base profile, also in L-shape, Figure 5a schematically, a C-shaped base profile with a complementary L-shaped profile , in a frontal region of the longitudinal frame beam, Figure 5b the rear region of the longitudinal frame beam, covering the structure of the longitudinal frame beam of Figure 5 a, Figure 8 schematically, a first conformation of a profile flank, reinforced by edging, covering a complementary L-shaped profile, in the present example, Figure 9 another alternative conformation in relation to figure 6, showing a reinforced profile flank of a profile complementary here in L-shape, Figure 10 schematically, a complementary profile in L- here produced as basic shaped unit- with variable wall thicknesses.
    [00049] In figure 1, a top view is shown schematically and principally for a longitudinal beam structure of frame 1 of a chassis frame of a utility vehicle, for example a truck or a bus, which has two longitudinal beams of frame 2, reciprocally distanced and essentially projected in parallel and reciprocally converging and projecting, in the assembled state shown here, in the longitudinal direction of the vehicle X, of modular structure, and which, in the example presented here, are of equal construction, that is, identical, which, however, would not necessarily have to be the case.
    [00050] As can be seen especially from the overall view of figures 1 and 3 (figure 3 shows, schematically one of the two longitudinal beams of frame 2 in a main and perspective presentation), the longitudinal beams of table 2 present here a base profile 3, presenting here an L-profile cut, which essentially extends over the entire length of the longitudinal beam of frame 2 and, in addition, it is rectilinear and not curved, so that the base profile in L presents a continuous continuous profile cut, that is, constant.
    [00051] Concretely, the base profile 3 here presents a central thread 3a that extends essentially towards the elevated axis of the vehicle, that is, in the vertical direction Z (see figure 1) in an upward direction, in which is formed a flank L 3b as a lower belt profile and here, in the example chosen, it stands out essentially in the transverse direction of the vehicle towards the inside, being here, for example near the two longitudinal beams in frame 2.
    [00052] As can be seen especially from figure 2a showing the cut along line AA, in connection with figures 1 and 3, in the central thread 3a of the base profile 3 and on the outside of the central thread 3a, in relation to the direction transverse to vehicle Y, a complementary front profile 4 is coupled with a profile cut in the shape of L. Specifically, here a vertical flank 4b of the front complementary profile L, 4, front, is coupled in a spatial way on the external side of the central thread 3a, and preferably - as can be seen especially from figure 4a - through a layer of integral glue 9 as an adhesive connection and with one or more screw connections 10 with closure due to the force. The adhesive connection 9 is not shown in figure 2a, for reasons of better visualization. Likewise, the number of screw connections 10, shown here in all figures, should also be understood by way of example only, in order to describe the idea of the invention in more detail, based on a concrete execution example.
    [00053] The complementary profile L 4 front also has a flank L 4a, which - seen in the transverse direction of the vehicle Y - points outwards from the central thread 3a, forming here an upper belt profile. In this way, in this frontal region of the beam, a longitudinal section of the longitudinal beam of the frame 2 of table 2 can also be seen in the longitudinal beam of frame 6, as can be seen especially in figure 2a.
    [00054] As long as it is considered necessary for the respective load case, that is, individual case, it is possible to mount additional reinforcement elements 11 on the longitudinal beam support of table 2, which, in the case of conformation according to the figure 2a, they are joined here - always as strips in the form of plates, by means of a glue connection, for example - with the side L 3b of the base profile 3 and with the side L 4a of the complementary profile L 4 front. Alternatively, or in an additional character, the reinforcement elements 11 can also be coupled to the respective construction component by means of a connection with screws 10, which in figure 2a is also drawn only by dashes, in an extremely schematic manner. The reinforcement element 11 can - as shown in figure 2c by dashes - also be formed by a profile component, in the present case an L profile.
    [00055] To reinforce regions and longitudinal beams of individual frame, especially in the case of thin wall thickness, for example, of the base profile 3, it can be predicted that defined areas have a stiffness 11a in the form of groove, which is designed in figure 2a in an extremely schematic way.
    [00056] As can also be inferred, especially with the comparison of figures 4a and 4b, in addition, there is the possibility - according to the use case and the load case, that is, type of vehicle - on the basis of a profile 3 proper, basically the same and identical, providing a cross-section in Z of the longitudinal beam of the frame, which differs in relation to its projection in height. This can simply be done, due to the fact that the complementary element 4 L - as shown in the comparison of figures 4a and 4b - for example for those use cases, a lower profile structure in the vertical direction is required in the frames, ie , with height axis Z, couple the profile of component 4 correspondingly deeper in the central thread 3a. The height offset is drawn here with L. This example, which was only explained here in more detail by way of example, in connection with the frontal region of the longitudinal beam of frame 6, naturally applies to any region of the longitudinal beam of frame 2, also for the rear region of the longitudinal beam of frame 7, which will then be described in more detail in connection, for example, with figure 2c. In connection with the conformations of figures 4a and 4b, it should be presented, just as an example and schematically, what the flexible conformation possibilities are available with the modular structure of the longitudinal frame beam according to the invention. In particular, it is also possible, for example, to form the base profile 3 of a material other than one or more complementary profiles. In the same way, the base profile and complementary profiles can have wall thicknesses, that is, different material thicknesses.
    [00057] It is also possible as an alternative for the conformation, according to figure 2a (see figure 2d), for example, in the case of the largest curve of the desired largest wheel, shorten the profiled flank 4a, shown in figure 2a and, when instead, apply on the opposite side of the central thread 2a, another complementary profile - L-4 which has a profiled flank 4a which is also short and correspondingly does not harm the area built in the transverse direction or in another way. In this way, an identical and rigid profile cross-section is made available which, in a simpler way, can be formed from various profiled construction components and without the need for complex technical finishes. The modular coffin according to the invention therefore allows - as shown by the example that can be used in a similar way for any other region of the frame's longitudinal beam - a simple, flexible construction according to the needs of a longitudinal beam from the board.
    [00058] Furthermore, it can be seen, from figures 4a and 4b, that the adhesive connection 9 maintains the two components, which are the base profile 3 on the one hand and the complementary profile-L 4 at a distance of such a defined way that in this way, also in the case of different materials, contact corrosion is avoided. According to the thickness of the adhesive connection 9 used, a certain damping and vibration behavior of the frame's longitudinal beam can be adjusted, that is, the structure of the longitudinal beam of the frame 1, altogether.
    [00059] Based on the coupling, only schematic and exemplified of the complementary front profile 4-L, in the base profile 3, in a global view with schematic presentation of figure 1, another embodiment of the invention, especially preferred, may be presented. Thus it can be well verified especially from figure 2a and also from figures 4a and 4b, that the complementary profile-L 4, in addition to the adhesive connection 9, by means of one or several connections with closure due to the force, especially by screw connections 10 , being fixed in the central thread 3a of the base profile 3, in order to exactly align with each other, the construction components to be interconnected (base profile 3 and complementary profile 4), before the adhesive connection 9 hardens, this being alignment and positioning done exactly in a reciprocal sense, which means prefixing. The construction component that is thus provided with adhesive connection 9 and which has the screw connections 10, will be in the context of a common coated KTL lacquer, and based on the high temperatures of the KTL coating there is a hardening of the adhesive connection 9 , so that the complementary profile-L 4 will be coupled to the base profile 3, both by the adhesive connection, through the adhesive connection 9, as well as by the screw connections 10, with virtually double security. In this case when, for example, other connections always fail, the other connection technique can continue to perform, that is, accept the support and connection function.
    [00060] The screw connections 10 have in the especially preferred case also the screw connections, by means of which another construction component of the frame structure of the longitudinal beam of frame 1, here, for example, a front beam 12, is in any case connected to the longitudinal beams of opposite frame 2. The screw connections 10 therefore perform here only in a dual function, in addition to the attachment of additional construction components, according to the example of the front cross member 12, they also actually prefix one or more complementary profiles in the base profile. 3, before the respective connection is hardened by means of glue.
    [00061] Of course, it is also possible to let the connection harden by glue also by means of a coating process, which eventually still requires more time.
    [00062] At this point, it will again be expressly mentioned that the front beam 12 here was selected merely schematically and by way of example, but of course other connecting elements of building components, that is, of connection in the structure, can also be used. of the longitudinal frame beam, in analogous form, for example, an engine support, a gear handle, a fender, etc., to mention just a few examples.
    [00063] It should be mentioned at this point that, instead of threaded connections 10, connections by rivets may also be provided. In the same way, it would be basically possible instead of the connection elements with closure due to the force, for the effect of the pre-positioning of the complementary profiles in the base profile 3 to provide a connection technique with closure due to the shape, that is, combined techniques of connection with closure due to shape and closure due to force.
    [00064] The above explanations apply in a similar way, and in the direction of transfer, also to the rear region of the longitudinal beam of frame 7, in which, as can be seen especially in figure 2c, which shows a CC section of the figure 1, the base profile 3 is complemented by means of a L-shaped front complementation profile 5, for a C-shaped profile cut, whose flank 5a and 3b in L points towards the inside, always in the direction of the another longitudinal beam of frame 2. There is also the spatial coupling of a vertical flank 5b of the complementary profile-L 5 in the central thread 3a, in an advantageous way, by means of a glued spatial connection, not shown in detail in figure 2c and, for example, a screw connection 10, of course here, too, only an adherent connection or a screw connection can be provided (as an example for a connection with a lock due to the force).
    [00065] Furthermore, it can be seen from figure 2c that here, if necessary, in the form and manner explained above, reinforcement elements 11 with stiffening action can also be mounted or provided.
    [00066] The coupling of the complementary profile-L rear 5 can basically be done precisely as shown in figure 2a, in connection with the complementary profile-L front 4, that is, with a vertical flank 5b, continuously straight and not curved, in the direction of the longitudinal beam beam projection. Alternatively, this vertical flank 5b, however, can also have, in the transition region, in the area of the profiled flank that exceeds the central thread 3a, of the vertical flank 5b, providing an angle, that is, a curvature 13 of this type, in a way that the area of the profiled flank 14 that exceeds the central thread 3a of the base profile, is so out of step by the thickness of the wall of the central thread 3a, that this region exceeding the flank of the profile 14, together with the central thread 3a, forms a outer face 15 flat, essentially continuous, which is especially advantageous when - as can be seen in figure 2b showing the cut along the BB line in figure 1 - the two complementary profiles-L 4, 5 are coupled on opposite sides of the central fillet 3a of the base profile, reciprocally overlaps in a central region of the longitudinal frame beam, that is, in an overlapping region 8, in the direction of projection of the longitudinal frame beam, because the yes it is ensured that also the area of the profile flank 14 that overtakes, being relative to the complementary profile-rear L 5, touches a spatial coupling on the correspondingly allocated vertical flank 4d, that a continuous spatial support connection of the vertical flank is ensured 4b of the front complementary profile-L 4 in the overlapping region 8, both in the central thread 3a of the base profile 3 and also in the vertical side 5b of the complementary profile-L rear 5. Also between the two vertical sides 4b, 5b, the connection can be basically formed as a glue and / or closure connection due to the force and / or closure due to the shape. In the same way, it would also be possible not to provide for any additional connection measures in the support region of the region of the profile flank 14 on the vertical flank 4b of the complementary profile-L front 4, in the region of the overlap 8, both in the central thread 3a of the profile base 3, as well as on the vertical flank 5b of the complementary profile-L rear 5. Also between the two vertical flanks 5a, 5b the connection can basically be formed as a glue and / or closure connection due to the force and / or closure due to the form. In the same way, it would also be possible not to provide for any additional connection measures in the support region of the protruding profile flank region 14, on the vertical flank 4b of the complementary profile-L 4 front, but to ensure a mere support connection of these two flank regions. in the central fillet 3a of the region that exceeds the base profile 3.
    [00067] Also when in connection with figure 2b, the two L-flanks 4a and 5a that make up the upper belt are located at the same height which corresponds in connection with the shape of figure 2b of making a D-profile, these two complementary profiles-L 4,5 can of course also be mutually out of date, which is shown schematically as an example in figure 3.
    [00068] As has been mentioned several times before, both in the central region of the longitudinal beam in Table 8, as well as in the rear region of the longitudinal beam in Table 7, the screw connections presented here as an example, can serve as connections with closure due to the force in a double function, both from the prefixing of the respective complementary profile in the base profile 3 and this until the envisaged adhesive layer is hardened and additionally also used for the coupling of other construction components, which is shown in connection with the rear region of the frame longitudinal beam 7 schematically and as an example, with the rear cross member 16.
    [00069] The indications made allow us to understand without difficulty that the base profile 3, which essentially extends throughout the longitudinal section of the longitudinal beam of frame 2, in a straight and non-curved direction, is formed in one piece, that is, especially of a single material and / or in one piece, while the complementary profiles extend only over the partial region of the longitudinal projection of the longitudinal beam of frame 2, that is, of the base profile 3.
    [00070] As shown in figures 6 to 8, only based on the complementary rear profile-L 5, but what could likewise apply to the complementary front profile-L 4, that is, for each complementary profile, ie , for each base profile, the reinforcement element 11 could also be realized by marginal bending, that is, edging 17 of the free end of the L-flank 5a. In the conformation, according to figure 6, the border is made in such a way that the bordered region 17, that is, folded, at least in certain regions, leans against a spatial connection in the remaining part of the -L 5a flank. Figure 7 shows the embodiment, in which the beaded, i.e. folded, area 17 has a defined gap distance from the remaining region of the L-flank. For this purpose, the embossed region 17 is supported here with its free front edge 18, on the vertical flank 5b of the complementary profile 5.
    [00071] Figure 8 finally presents an execution variant, in which the complementary profile 5, in the region of the vertical flank 5b, presents a material thickness, essentially thinner than the L-flank 5a, for example, the thickness of material d of the vertical flank 5b, corresponding approximately to half the thickness of material D of the L-flank 5a. For example, the material thickness d of the vertical flank 5 can be in the range between 3 to 5 mm, while the material thickness d of the L-flank 5a can be approximately between 6 to 8 mm. A profile of this nature, with varying material thickness, can, for example, be produced in the context of smooth geometry. In the case of figure 8, therefore, the reinforcement element 11, different from what happens in figures 6 and 7 - is not formed by a bordered region 17, but is an integral component of the L-flank.
    [00072] As mentioned above, the above applies basically in connection with any other complementary profile, that is, with the base profile 3.
    [00073] Figure 5 finally presents yet another alternative conformation of the present idea of invention, in which the base profile 3 presents a continuous C-shaped cut, so that for the conformation of a Z-shaped profile cut, in region of the longitudinal beam of the front frame 6, shown in figure 5a, there should only be a complementary profile-L 4 there, whereas in the longitudinal region of the rear frame 7, shown in figure 5b, due to the existing C-shape in base profile 3, no additional profile should be provided here. Here, too, the connection of the complementary profile L 4 analogous to the shape and manner described above can be made by means of one or more screw connections 10 and / or a spatial bonding connection.
