    The conventional leaf springs formed by slats and spanners do not allow an easy simple adaptation to the chassis of mainly cargo vehicles with chassis equipped with pneumatic suspensions and of complex structure, for which reason the invention proposes a spring formed by pieces based on two tubular profiles that are incorporated to the shaft by its area of overlap with the help of an angular support, screws and nuts, and that at one end has the corresponding eye while at the other end an arm has a widening for the support of a pneumatic cushion, placing the arms in different and parallel planes, and its form of attachment to the chassis is standard, also eliminating the blades, and using standard screws.

    DESCRIPTION
    Crossbow formed by two arms attached to an axis.
    Object of the invention
    More specifically, the invention relates to a special crossbow, formed by two tubular sections, in the form of arms joined to said ends by their ends in an overlapping zone, by means of the corresponding screws and nuts that cross the extreme parts of said arms, right of the left and left arm of the right arm, the arms located in different and parallel planes.
    State of the art
    The invention corresponds to the automotive sector and, more specifically to the component industries for said sector, especially for cargo vehicles, trailers and trailers, in which the axles thereof and their crossbows are subject to high loads .
    Within the automotive sector are the manufacturers of crossbows which, as is known, act as a means to support the load of the vehicle and, absorb the shocks produced by the passage of the vehicles, in this case loading by a bump or irregularity of the road , highway or similar road, said crossbows being formed by the superposition of steel slats of different length, thickness and width.
    These slats are pressed against each other, by means of a bolt called cappuccino and, they are kept aligned by means of clamps called rods to prevent them from opening in a fan.
    Other types of crossbows such as those formed by a single solid plank are also known, they place the eye of the crossbow at its ends, the same one of its ends formed by a substantially circular bending thereof, in which the twin is incorporated , while at the opposite end the crossbow ends in a widening in the form or plate on which it rests and, it mounts suspension means of the front axle of the vehicle, or to the chassis thereof, so that said widening is made in a only extreme is the solid lama.
    It is not known the existence of crossbows formed by two tubular sections mounted in distant and parallel planes and, which allows modular solutions, simplicity of assembly and cost savings in its components as part of the same market standards, which do not require of its own design and specific manufacturing only applicable to the crossbows in question.
    Purpose of the invention
    Solve by means of the combination of two arms or parts mounted above and below the axle and subject by screws incorporated to the chassis by means of an angular support, the problems that arise in vehicles with different chassis and different axes, which force them to have different types of crossbows for each and, different types of complementary elements for each crossbow as are the rods, screws, brakes, plates, different bearings.
    Achieve a robust crossbow design by being formed, inter alia, by two parts or arms, which are incorporated into the axle of a vehicle, formed among others, by said axle and a suspension system so as to use the standard axes of said vehicles, shaped

    of attachment to the chassis also standard, eliminating the same as well as the bolts, and using standard screwdrivers, commercial bolts, bearing plates also standard, with the particularity that the tools used to mount them are also.
    Another purpose of the invention is the ease of the crossbow to adapt to an environment, that of the changing spring that requires new quick and easy solutions, while not presupposing a high cost of adaptation of the base crossbow of the invention.
    Another of the purposes of the invention is the possibility of both one end of one of the arms and the end of the other arm making it possible to integrate expansions that allow the crossbow to adapt to different types of suspensions and chassis of different vehicles.
    Description of the invention
    It consists of the superposition and subsequent union of two tubular arms located in parallel planes of different heights, by interposition perpendicularly between the two previous arms of a standard axis, joined the three pieces, the two arms and the axis by means of commercial bolts and nuts, as well as a standard plate adjustable to the chassis, mounting a standard bearing to one of the eyes of the crossbow.
    One of the arms has a shape, resulting from the programmed deformation of a tubular section, which results in an end of said arm, substantially flattened and flat, which allows the possibility of integrating expansions to increase the surface of attachment to the dampers or equivalent elements, at the same time that said arm can vary its length depending on the solicitations of each case.
    To reinforce the union of the two arms of the crossbow, in the overlapping zone at the end of one of the arms, stripes and / or deformations can be projected, which help in combination with others provided on the axis, whichever said union is totally immovable by both axial, normal and torsional stresses.
    As for the material used for the manufacture of one of the signaling arms that does not require the same quality, nature and technical requirements as the arm, which is why any suitable material could be used, with the only limitation that does not offer any type of difficulty in welding operations.
    Likewise, the shape of one of the arms can be easily adapted to the height requirements in a simple way by varying the curvature of the arm or by mounting it rotated 360 ° with respect to the other arm, with standard and simple tooling.
    The other arm, like the first one, has a configuration resulting from the programmed deformation of a tubular section, from which an end substantially flattened by one of its ends derives, while at the other end a widened area has been machined, in the which has provided the eye of the crossbow, in which the corresponding standard bearing with its bushing is inserted, thanks to two skirts provided in the widened area.
    Both arms can vary the length depending on the needs of the environment and solicitations, in addition to those pointed out above, helping the versatility of the recommended crossbow, which acts assuming the spring effect, reducing the effort on the bushing.
    The arms are joined in parallel, not coplanar, thanks to an axis designed to adopt a substantially cylindrical configuration and, in its central area, outward deformations in the form of a curved plateau, which facilitates the union with the parts

    ends of both arms provided with the corresponding grooves, which are carried out through the use of conventional screws and nuts.
    The provision of projections and / or deformations in the axis of the direction in combination with projections embuticiones in the ends of the arms and, the help of screws and nuts previously mentioned, help to the solidity of the union not only with respect to axial efforts but torsional
    Finally, another part of the recommended crossbow is an angular support to be able to attach the recommended crossbow to the chassis, equipped with both its vertical and horizontal part, of two holes to allow the mounting of the crossbow to the chassis, the distance between the holes will be standard as well as its thread and the so-called thread pitch, said support being able to receive a thermal treatment if necessary.
    Other details and characteristics will be revealed in the course of the description that follows, in which a graphic representation of the invention is shown by way of illustration but not limited to, which may be implemented with any type of materials and measures that conform to the planned solicitations.

    Description of an embodiment of the invention
    In one of the preferred embodiments of the invention and, as can be seen in Figures 1 and 2, the crossbow (10) comprises as main elements the following:
    - An arm (10a).
    - An arm (10b).
    - A shaft (11).
    - An angular support (12) with its connecting rod (21).
    - Some screws (30).
    - Nuts (23).
    The arm (10a) of the crossbow (10), as can be seen in figure 6, has clearly differentiated areas, at one end a flat area (13) that after a change in width extends towards the other end in an intermediate tubular zone (14) of substantially rectangular section with blunt vertices, which in turn ends in the overlap handle (18).
    The central area of the overlap handle (18) and its upper concave configuration surface forms the depressed zone (10c), while on the inner surface of the overlap handle (18) it has flare areas (20a) and (20b) see figure 13, as well as in said overlap handle (18) as can be seen in detail in figure 6, the inlet and outlet holes (22) are provided as mouths of the areas threaded tubular (31) and non-threaded tubular areas (33). The function of the longitudinal projections (29) is to facilitate the assembly of extensions not shown in the figures.
    The arm (10a) has at one of its ends (18), which we will call an overlap handle an opening (19) as can be seen in figure 2 and, in the vicinity of it, threaded tubular areas (31 ) of thread (32), through which the screws (30) are threaded, as can be seen in figure 13, which work in combination with other non-threaded tubular areas (33), provided on another arm (10b ) at its end near the mouth (27).
    In turn, in the depressed area (10c) of the arm (10a), as can be seen in figure 6, if necessary, stripping strips and any other equivalent solution, not shown in the figures, can be machined in combination with lateral surface
    (11.4) and the seal (11.5) overlap in the shaft tube (11) and, help retain one end of the arm (10a), with said end of the arm (10b), forming an overlapping zone (34) that it is distinguished in strokes in figure 5, when the screws (30) are introduced through the inlet and outlet holes (22) in the threaded tubular areas (31) as can be seen in figures 11 and 13 and , of the non-threaded tubular areas (33) and subsequently screw the nuts (23) at the ends of said arms the screws (30), see also figure 3.
    The arm (10b) as can be seen in Figure 7, in turn has a widened part (20), of formal and functional characteristic identities than those of the arm (10a), which extends towards the end in a intermediate tubular zone (24) of substantially rectangular section of blunt vertices, whose height varies from one end to the other and, which ends in a widened area (28) in which the eyes of the crossbow (10) are provided, formed by the hole (16) the skirts (26) and, the bearing (17) that is mounted on said skirts (26), the opening of the widened area (28) being distinguished by (15).
    In the upper part of one of the ends of the arm (10b), there is the widened area (20) in which an angular support (12) is coupled, the detail of which can be seen in the
    Figure 15, and comprising a vertical part (12.1) and a horizontal part (12.2), affected (12.1 - 12.2) by two holes (35), located at standard distances, which allow insertion into said holes (35) of a connecting rod (21) comprising a head (21.1). Said angular support (12) allows the fastening of the crossbow (10) to the chassis of the vehicle in the appropriate position, thanks to the holes (35).
    Between the arm (10a) and the arm (10b), located at different heights but in parallel, the axis (11) of substantially cylindrical configuration, of openings (11.1) and (11.2) and whose lateral surface (11.4) is mounted it is affected by two extensions in its central part directed outwards, as can be seen in figures 4c and 4d, forming the plateaus 10 (11.3), as can be seen in figure 5 in which fit these plateaus (11.3) with
    the depressed areas (10c) and (10d).
    On the other hand the arms (10a-10b) of the crossbow (10) can be mounted in the ways in which figures 9 and 10 are represented, in the first figure n ° 9 the crossbow (10) the widened area (28) looks down, while in the second figure No. 10, the widened area 15 (28) looks down above.
    Described sufficiently the present invention in correspondence with the attached figures, it is easy to understand that any modifications of detail that are deemed convenient may be made therein, provided that the essence of the invention that is summarized in the following claims is not altered.
