    According to a preferred embodiment, the reinforcing element comprises at least one fold in the longitudinal direction defining at least two essentially flat surfaces, such that a separation distance between each of the at least two essentially flat surfaces and the adhesive track It is variable, between the at least two essentially flat surfaces and the adhesive track being the mounting assembly and / or the side panel and / or the crossbar.
    As we have seen before, each of the metal plates is of different materials and, above all, of different thicknesses, in order to obtain a balance between weight and optimum mechanical resistance for each of them. In addition, to perform spot welding, the clamps must be essentially perpendicular to the plates to be joined, without having air or empty space between them. That is why the common element throughout the knot, the reinforcing element, has folds in the longitudinal direction, in order to adapt to the different thicknesses of the intermediate pieces arranged between the essentially flat adhesive track and the cited reinforcement element. Only in this way will the welding points be possible.
    Furthermore, the assembly system according to the present invention may comprise at least a third welding point located in the first essentially transverse portion and spacing of the first welding point, where the at least a third welding point fixes the reinforcing element , the crossbar and the roof.
    It should be noted, however, preferably there are a plurality of third weld points and they are distributed along the transverse portion, being able to be equidistant from each other. In this way, the sleeper is also joined by a union of three thicknesses. In order to ensure the correct coupling and structural behavior of these components, a plurality of welding points must be made along the first portion of the adhesive track.
    The system according to the present invention can also comprise at least a fourth welding point located in the second essentially longitudinal portion and spacing of the second welding point, where the at least a fourth welding point fixes the side panel and the mounting assembly . Thus, the side panel will be additionally attached to the upright assembly, improving the rigidity and mechanical behavior of the knot.
    It should be noted, however, that there are a plurality of fourth weld points and are

    wherein the adhesive track comprises a first essentially transverse portion, a second essentially longitudinal portion and a corner disposed between the first portion and the second portion, characterized in that it comprises the steps of: a) joining the mounting assembly with the reinforcing element by means of a second welding point arranged in the second essentially longitudinal portion of the adhesive track, where the second welding point is adjacent to the corner, b) joining the side panel with the mounting assembly by at least a fourth welding point arranged in the second essentially longitudinal portion of the adhesive and spacing track of the second welding point, c) joining the roof, the side panel and the reinforcing element by means of a first welding point arranged in the first essentially transverse portion of the adhesive track, where the side panel is between the roof and the reinforcing element, and where the first welding point is adjacent to the corner, and d) joining the roof, the crossbar and the reinforcing element by at least a third welding point arranged in the first essentially transverse portion of the adhesive and spacing track of the first welding point.
    It should be noted that in case the upright assembly has a cover and reinforcement, a preliminary welding stage is first performed between the cover and the reinforcement element. In addition, stage d) can be carried out before stage c), or vice versa.
    The assembly process according to the present invention may also comprise an additional step of joining the roof and the crossbar by at least a fifth welding point located in the first essentially transverse portion of the adhesive and spacing track of the at least a third welding point, and may also comprise an additional step of joining the side panel and the mounting assembly by at least a sixth welding point located in the second essentially longitudinal portion of the adhesive and spacing track of the at least a fourth welding point .
    Consequently, a solution has thus been achieved in which a fabricable knot is achieved with an excellent compromise between stiffness and length of the adhesive track. Thanks to the use of the first inclination of the cross-sectional portion of the roof arranged in the corner, the parallel inclination of the ramp, the at least one fold in the longitudinal direction of the reinforcing element, an assembly is achieved by points


    welding in which none of the points converge more than three thicknesses. In addition, all components are continuous and have neither holes nor crevices, a fact that improves the rigidity of the pieces and the assembly.

    25 Description of a preferred embodiment
    The assembly system according to the present invention allows assembling different subsets of a vehicle body, specifically in the knot
    30 composed of various pieces of sheet metal in the interference zone between a roof 2 and a vehicle upright assembly 4, being able to apply both to the existing knot between roof 2 and front upright and to the existing knot between roof 2 and rear upright.
    The exposed drawings correspond to the assembly of the node formed between the roof 2 and the previous upright assembly 4, also known as pillar A. Thus, as can be seen

    in Figure 1, the vehicle body comprises: - an upright assembly 4, preferably formed by a stiffener reinforcement 44 and an upright cover 45, and comprising a first transverse end 41 that partially limits an adhesive track 9; - a side panel 3 covering at least part of the upright assembly 4 and comprising a ramp 31; - a cross member 6 that extends transversely in the body of the vehicle and with an end disposed substantially opposite one end of the side panel 3; - a roof 2 supported by the crossbar 6 and comprising a first transverse end 21 that partially limits the adhesive track 9; and - a reinforcing element 1, such as a bracket, arranged below the upright assembly 4 and the cross member 6, comprising at least one longitudinal fold 11.
    The roof 2 and the side panel 3 form an essentially flat adhesive track 9 on which a transparent screen, such as a windshield or a window, rests.
    Said adhesive track 9 comprises a first essentially transverse portion 91 and a second essentially longitudinal portion 92, a corner 93 being arranged between said first 91 and second 92 portions.
    It should be noted that in the present description and in the appended claims, the longitudinal and transverse terms refer to the direction of travel of the vehicle.
    These components are joined together by a plurality of welding points 101-106, as will be described below, said welding points joining a maximum of three thicknesses. It is important to note that, in the node where the present invention is applied, there are a multitude of welding points. On the other hand, only the welding points 101-106 applied on the adhesive track 9, object of the present invention and solving the problems described above, are described.
    The arrangement of these components and welding points can be seen in the figures, in particular in Figure 2, where a sectional view is shown. Specifically, this cross-section cuts the adhesive track 9 so as to visualize the arrangement of the body sub-assemblies, as well as the welding points arranged in the corner 93.

    In accordance with the present invention, the first transverse end 21 of the roof 2 extends in the first essentially transverse portion 91 and at least partially in the corner 93, while the first longitudinal end of the upright assembly 41 extends in the second portion 92 essentially longitudinal and at least partially in corner 93. In this way, at least 93 metal plates converge in corner 93, which cannot be welded by a single welding point.
    A first welding point 101 comprised in the first portion 91 fixes the roof 2, the side panel 3 and the reinforcing element 1, the side panel 3 being between the ceiling 2 and the reinforcing element 1, and a second welding point 102 comprised in the second portion 92 fixes the reinforcing element 1 and the upright assembly 4. Said first weld point 101 is adjacent to corner 93 in the first essentially transverse portion 91 of the adhesive track 9, and said second point of Welding 102 is adjacent to corner 93 in the second essentially longitudinal portion 92 of the adhesive track 9, at a suitable distance to allow welding.
    As indicated above and as can be seen in Figure 2, but in more detail in Figure 3 above, a portion of the side panel 3 arranged in the corner 93 comprises a ramp 31. This ramp 31 allows that in the first portion 91 of the essentially transverse adhesive track 9 the side panel 3 runs under the roof 2 and in the second portion 92 of the essentially longitudinal adhesive track 9 the side panel 3 is substantially flush to the roof 2. Thus, the roof 2 and side panel 3 form an essentially flat adhesive track 9.
    Furthermore, according to the embodiment shown, said ramp 31 comprises a second inclination substantially parallel to the first inclination of the transverse end of the roof 21 disposed in the corner 93, said first inclination of the transverse end of the roof 21 being substantially 45 °, although it could have any proper inclination. Furthermore, said inclined vertex of the ceiling 2 arranged in the corner 93 allows a confluence of no more than three thicknesses on both sides of the corner 93, enabling the first welding point 101 and the second welding point 102. Furthermore, this particular geometry prevents the lifting of the vertex after the application of the welding point.
    Advantageously, as shown in Figure 2 but in more detail in Figure 3 below, the reinforcing element 1 comprises at least one fold 11 in the direction

    Additionally, as can be seen in Figure 7, the assembly system can also comprise at least a fifth welding point 105 located in the first essentially transverse portion 91 of the adhesive track 9 and spacing of the third welding point 103. This fifth welding point 105 joins the roof 2 and the crossbar 6.
    5 Finally, also shown in Figure 7, the assembly system may also comprise at least one sixth welding point 106 located in the second essentially longitudinal portion 92 of the adhesive track 9 and spacing of the fourth welding point 104. This sixth welding point joins the side panel 3 and the upright assembly
    10 4.
    The present invention also relates to the assembly procedure of the subsets described above.
    The steps of the process according to the present invention can be seen in Figures 5 to 7.
    First of all, it should be noted that if the upright assembly 4 is formed by an upright reinforcement 44 and an upright cover 45, as shown in the figures, before the
    20 steps described below it is necessary to join the upright reinforcement 44 and the upright cover 45 together.
    The first stage of the process according to the present invention consists in the union of the upright assembly 4 with the reinforcement element 1 by means of a point of
    Welding (second welding point 102 according to the above description) disposed in the essentially longitudinal second portion 92 of the adhesive track 9, and where the mounting assembly 4 is disposed above the reinforcing element 1.
    Next, the side panel 3 is joined with the upright assembly 4 by at least one
    30 welding point (fourth welding point 104 according to the above description) disposed in the essentially longitudinal second portion 92 of the adhesive track 9 and spacing of the second welding point 102, and where the side panel 3 is arranged above the upright set 4.
    35 Subsequently, a positioning of the roof 2 is carried out with respect to the assembly already assembled. Thus, the first inclination is positioned with respect to the longitudinal direction of


    the portion of the transverse end of the roof 21 substantially parallel to the ramp 31 of the side panel 3.
    Next, the roof 2, the side panel 3 and the reinforcing element 1 are joined by
    5 a welding point (first welding point 101 according to the above description) disposed in the first essentially transverse portion 91 of the adhesive track 9, where the side panel 3 is between the roof 2 and the reinforcing element 1, and where the first weld point 101 is adjacent to corner 93.
    10 Finally, the roof 2, the crossbar 6 and the reinforcing element 1 are joined by at least one welding point (third welding point 103 according to the above description) arranged in the first essentially transverse portion 91 of the track adhesive 9 and spacing of the first weld point 101, and where the cross member 6 is between the roof 2 and the reinforcement element 1.
    15 It should be noted, however, that these last two stages can be performed interchangeably in the order indicated or in the reverse order.
    If desired, the process according to the present invention can also
    20 comprises an additional step of joining the roof 2 and the crossbar 6 by at least a fifth welding point 105 and joining the side panel 3 and the mounting assembly 4 by at least a sixth welding point 106.
    Although reference has been made to a specific embodiment of the invention, it is
    It is clear to a person skilled in the art that the described system and assembly procedure are susceptible of numerous variations and modifications, and that all the mentioned details can be replaced by other technically equivalent ones, without departing from the scope of protection defined by the appended claims. .
