    Once both structures are defined, which are fixed in the plurality of support points, it should be noted that the union of the whole assembly generates an aerodynamically advantageous cross section, which consists of a continuous vertical part that covers the lateral area of the wheels, from which a sheet inclined to the wall of the tank with an obtuse angle with respect to the vertical part. For this, it should be noted that there is perfect continuity between the vertical sheet of the upper structure and the entire vertical surface formed by the upper bar and the plate or skirt of the lower structure. As we have defined, a lateral profile is generated consisting of two edges joined by a vertex that with an obtuse angle, that angle being between 120º and 165º, and preferably around 150º, in which the angled edge closes with the circular wall of the cistern. This configuration allows that the air displaced with the movement of the truck is not introduced in the area of the wheels, generating therefore an increase of the resistances and of the consumption of fuel, but that the air will move towards the rear part of the truck.
    To give continuity to the configuration of the support and the truck, in the rear part of the semi-trailer or truck, this form is also respected, for which several support points are also attached to the chassis of the truck that allow to fix an upper structure and a structure bottom with a fixed plate or skirt without the possibility of being knocked down, since in the rear part the license plate, the lights of the gauges, rear skirts, and other necessary elements of any transport vehicle are located. Also in that rear area a series of gates, preferably circular, are opened with which the longitudinal cabin generated by the upper structure defined above can be accessed.
    In order to complete the description that is being made and in order to help a better understanding of the characteristics of the invention, a set of drawings is attached as an integral part thereof, where the following has been represented as an illustrative and non-limiting nature:

    Figure 1 is a free perspective representation of how the aerodynamic support (1) is integrated in each side of the semitrailer of a tank (2) or of the tank truck, in which the aerodynamic support introduces itself is a structure lateral of superficial planes that eliminate friction angles 20 from the body. As can be seen in this figure, the aerodynamic support
    (1) is composed of two differentiated parts, an upper part or structure (3) with an inclined surface or sheet (30) that comes into contact with the curved wall of the cistern (2) and a vertical surface or sheet (31) , and by a lower part or structure (4) having a plurality of plates (41) or skirts that are
    25 support in bars (40). It can be seen how the rear part of said tank also keeps the aerodynamic shape. This aerodynamic support (1), which as we have mentioned is located on each side of the tank (2), acts in the lateral areas, reducing the resistance to the advance in the area of the wheels

    of support (5), and two cross sections (I-I´ and II-II´) shown in Figure 7 and 8 in which the aerodynamic support section (1) is enlarged.
    Figure 5 is a free perspective representation of a foothold (5). This support point has such a configuration that it has a vertical metal profile (50) that allows the attachment to the frame (8) of the truck, that is to say the structure or frame that supports the tank; and on the other hand, it has a plate (51) that is perpendicular to the previous one and serves so that the upper (3) and lower (4) structures are supported and fixed on it. Specifically, the vertical metal profile that is fixed to the frame (8) is formed by two tabs (50) parallel to the outer surface of the frame (8), and which are drilled (501) for the fastening fasteners to the frame. On the other hand there is a plate (51) located in a horizontal plane. The plate (51) and the two tabs (50) are joined by two metal plates (52) located in a plane perpendicular to the one of the tabs (50). The horizontal plate (51) has a central lightening (510) and a series of holes
    (511) on its sides that allow fastening by screws to the upper structure (3), while it has two flange flanges (520), also with holes (521), whose function is to fix the lower structure (4).
    Figure 6 is an enlarged detail of an exterior view of the junction zone between a support point (5), the upper structure (3) and two ends of lower structures (4). As we have said, the point of support is the end of each of the multiple lower structures (4) that are longitudinally located, and that in each of them there is a sheet (41) or skirt.
    Figure 7 is the representation of section II of Figure 4, focusing on the area of the support point (5), or an enlarged detail of the lateral support shown in Figure 3. This figure shows how the support ( 1) it is constituted by an upper structure (3), closed and longitudinal, that generates a closed cabin (9); a lower structure (4) that supports the sheet (41) or side skirt; and the support point (5) fixed to the chassis (8), which fixes and supports both upper and lower structures. In the case of the upper structure (3), it can be seen how it generates a closed cabin (9) in the shape of an irregular quadrilateral. For this, there is a metal part that forms a horizontal base (32) that is fixed to the plate (51) of the


    support point (5), and going outside there is a vertical reinforcement (33), which serves as support for the vertical vertical sheet (31), moreover, it can be seen as the break
    (300) or vertex that generates the aerodynamic shape coincides with the end of said vertical reinforcement (33). On the other hand, the outer inclined sheet (30), which starts from that vertex (300) towards the curved wall of the cistern (2), is fixed to it by means of a rubber seal joint (34), that is, it is generated a longitudinal rubber gasket on the side of the cistern (2), which is represented in Figure 4. To improve this rubber gasket joint (35), the inclined sheet (30) has a protruding flap (301) that improves said coupling, this flap being
    (301) best represented in later figures. To finish the description of the upper structure, it can be seen that from the base (32) there is an inclined plate (34) that is also fixed at that point of connection between the inclined sheet (30) and the tank wall (2) , in such a way that it stiffens the assembly and closes the cabin. Finally, it is observed that the vertical sheet (31) will have a height such that it reaches the lower structure (4), so that visually from the outside there is total continuity and the support is at all times closed. In another order of things, in this figure it can be seen that the lower structure (4) is formed by longitudinal upper bars (40) with a certain profile which can be variable, with reinforced anchors (42) triangular in shape. areas of the support point (5) being fixed thereto by means of screws in the lower flanges (520) of said support point, and starting or hanging from each of these upper bars (40) there is a vertical plate (41) in the form of skirt In the junction zone between the bar (40) and the vertical plate (41) there is a longitudinal articulation axis (43) that allows the movement or articulation of said vertical plates. Going more in detail, it can be seen that the reinforced anchor (42) is preferably formed by a flat vertical plate and perpendicular to the plane of the plate (41) or skirt, triangular shaped, which has a flange (420) that is fixed by screws to the bottom flange (520) to the support point. In this reinforced anchor (42) a vertical beam (44) is fixed by screws, which is the one fixed by screws and stabilizes the upper longitudinal bar (40). So that the outer vertical plate (41) does not move, a closing element (45) is required, fixed on the vertical beam (44). In the case of


    The present figure shows that the closing element (45) is a threaded key in the lower part of the vertical beam (44) in contact with the vertical plate (41).
    Figure 8 is the representation of section II-II 'of figure 4, and being similar to the section of figure 7, but in this case at any longitudinal point on the side where there is no support point (5 ). This figure highlights the perfect vertical continuity existing in the vertical plane, that is, that the vertical sheet
    (31) of the upper structure (3), the upper bar (40) and the vertical plate (41) are continuous and coincident in plane; which together with the inclined sheet (30) form an aerodynamically improved section.
    Figure 9 is a free perspective representation of the outer part of the aerodynamic support, which can be seen to be formed by the upper structure (3) with its vertical sheet (31) and its inclined sheet (30) having the overlap protruding (301) at its end, and by the lower structure (4) with its longitudinal bar (40) and the vertical plate (41). In this figure it is seen how the angle formed in the vertex (300) generates an obtuse angle (β) with respect to the vertical, which is preferably between 120 ° and 165 °.
    Figure 10 is a schematic representation of the cross-sectional profile of the previous figure, in which the representation of the longitudinal articulation axis (43) which allows, when appropriate, the rotation of the vertical plate (41), and in which the angle (β) generated between the vertical plane of the support, formed by the vertical plate (41), the longitudinal bar (40) and the vertical sheet (31), and the inclined plane of the support formed by the inclined sheet is clearly visible (30), which may be between 120º and 165º, it is sought to be around 150º as an optimum angle and as a preferred embodiment.
