    BASKET ASSEMBLY FORMED BY MORE THAN TWO PIECES Object of the Invention
    More specifically the invention relates to a
    crossbow of thekindtire,istellwithcushion
    tire integratedinonehisextremes,that
    understands twosectionstubularthatbeuniteby
    overlapping its ends, and which are incorporated in the overlapping zone also intended for attachment to the vehicle's axis by means of flanges and safety means.
    Another object of the invention is another crossbow formed by two or more pieces, among others one of tubular section and another of full section (sheet of rolled steel) with the same purpose of the first.
    State of the art.
    The oldest crossbows conceptually speaking, as means to guarantee the contact of the wheel with the road in front of the irregularities of the terrain, and withstand the solicitations that derive from the dynamic load of the vehicle, are those that are formed by the union with overlapping slats of steel of different length, strength and elasticity, as well as of different thickness length and width, (conventional crossbow). These slats are pressed against each other by means of a bolt called cappuccino and, are kept aligned by means of clamps so that they do not open in a fan.
    Combining slats with different characteristics
    resistance thickness length and width, it is possible to cover different types of solicitations of each of them depending on the magnitude of load that supports the
    vehicle and also cover different rigidities, depending on its characteristics due to its
    application.
    One end of the crossbow is articulated to the
    rack using the twin "U" configuration,
    eight or suspension rod that when swinging allows the
    10 elongation of the crossbow during flexion, one of
    the arms of said twin is introduced into the eye
    surrounded by bushes with greasers and seals for
    save fat while the other arm of the
    twin articulates to the crossbar or support of the
    fifteen bodywork.
    Subsequently, crossbows have been designed where the
    trapezoidal section obtained by the combination of leaves
    of different lengths described in the previous section,
    it is replaced by a profile with one or several slats
    twenty solid, parabolic profile, that is the thickness of the
    section varies parabolically throughout its
    length (parabolic crossbow).
    The pneumatic crossbow part of the concept of
    parabolic crossbow, at whose ends the eye is located
    25 of the crossbow, formed at one end by a
    noticeably circular bending thereof, in which
    the twin is incorporated while at the end
    opposite the crossbow ends in a flat area or
    plate, on which the pneumatic cushion is supported and mounted,
    3 o by inserting a plate of between the plate and the cushion
    support for. The pneumatic cushion is connected to the chassis of the
    vehicle to transmit the efforts caused by the
    Vehicle dynamics and dampen vibrations.
    Occasionally, the support plate is removed
    causing a certain widening of the flat area, of
    so that this widening is done in one
    5 piece.
    The existence of single-leaf springs is unknown.
    slat formed by two different tubular sections, which
    ensure the benefits that result from two
    Tubular parts or sections. By the request of
    10 Spanish Invention Patent of the same holder
    201330845 whose object is a "Tubular Crossbow of
    variable section "is described and claimed in that the
    structure of the crossbow is an elongated body, which
    it has an internal hollow of variable section in its
    fifteen different longitudinal zones; being able to keep the
    walls of said inner hollow its constant thicknesses
    and variables along its longitudinal axis.
    On the other hand, in document US2002 / 105117
    report a crossbow (10). Said crossbow (10) comprises
    2 o a first elastic sheet (12) and a second sheet
    elastic (18). The first sheet (12) has a first
    end (14) configured as an eye for union with
    the vehicle chassis using an insert (16) and a
    second end (26). The second sheet (18) also
    25 It has a first end (20), configured as an eye
    for connection with the vehicle chassis by means of a
    insert (22) and a second end (24). The two sheets
    (12, 18) overlap each other in an area of
    central overlap between seconds
    30 ends (24, 26) of each sheet (12, 18). This area of
    overlap reinforces crossbow resistance (10)
    in the central region where tensions are maximum, which prevents the possibility of catastrophic breakage.
    A tubular crossbow is disclosed in document P201330845. Said tubular crossbow comprises a tubular body (1) that has a widened area (15) at the first end where an eye (3) is configured by means of an additional piece, or integrally, and which has a head at a second end support (2) for a pneumatic cushion. In addition, said tubular body
    (1) comprises conformations (12), such as through holes. Thanks to its tubular configuration, the aforementioned crossbow achieves an appropriate mechanical resistance and, at the same time, a reduced weight.
    In JP2004084758 a crossbow (18) is disclosed. Said crossbow (18) comprises a first elastic sheet (lla) with a first eye (12) at one end and a second elastic sheet (14a) with a second eye (15) at one end. Both sheets (lla, 14a) overlap in a central overlapping area adjacent to an axle (19) of the vehicle and are joined together by screws (16) and nuts (17). In addition, the plates (lla, 14a) are attached to the axle (19) of the vehicle by means of a support assembly (20) that uses bolted joints. Thus, a crossbow (18) is constructed in an inexpensive manner in which the first sheet (lla) is different from the second sheet (14a) from
    from crossbowsdifferent(eleven,14)thatThey aredividedby
    half.
    The improvementfromthesuspensionsfromthevehicles
    oblige tothemanufacturersfromcrossbowstoto be able to guarantee
    exactly the properties that characterize these crossbows, so that in combination with other elements
    of the suspension offer the requirements demanded before the solicitations caused by the loading of the vehicle before the irregularities of roads, highways and the like and, not approximately.
    The ends of the crossbows that we can consider as a state of the art, end in two eyes through which and with other elements they articulate themselves to the chassis of the vehicle, in which the bearings are mounted.
    Also the state of the art is known crossbows in which one of the ends is a plate

    Purpose of the invention
    By dividing the crossbow into two main parts, it is possible to integrate forming operations without chip removal into the process using means of energy consumption considerably lower than that required to obtain similar shapes in solid sections. This makes it possible, for example, to integrate part of the flange elements into the profile, in particular; In the current embidases, two upper flange plates are used, (which embraces the crossbow by its upper face) and lower (which embraces the crossbow by its lower face and to the axis by its upper face). Both plates are fixed to each other by means of threaded U-pieces at their ends (curbs) and tightening nuts, forming a package that guarantees the union between the shaft and the crossbow. The proposed solution eliminates the need for the top plate whose function is integrated into the profile. Description of the invention
    The proposed invention breaks with the known concept of pneumatic leaf springs, formed by a sheet of the same material that is attached to the shaft by means of a flange formed by 2 anchor plates and 2 rods and shows a new type of crossbow formed by two main parts that join by overlapping by one of its ends, being able to execute under this new concept alternative versions, in which the two

    Description of an embodiment of the invention.
    In one of the preferred embodiments of the invention and as can be seen in Figure 2, the crossbow (10) as a main feature of the present invention is formed by two parts

    Tubular insertable part (lOa) and, right part
    (10b) also tubular, see figures # 1 and 2. Insert (lOa) of solid section and right part of tubular section, see figures # 3 to 5.
    According to another of the characteristics of the invention, the sections of the tubular profiles of the parts (10) and (10b) have been designed to allow an overlapping zone (11) of the ends of (10 and 10b) of the crossbow (10), with a configuration of the aforementioned sections of substantially rectangular perimeter with blunt vertices, with two major upper and lower bases (23) and (24) respectively on the right side (1 Ob), as shown in Figure 1 and, two lateral bases (22), so that the tubular part (10b) in the overlapping zone (11), includes a stud
    (30) that penetrates a hole (31) of the insertable part (10) as can be seen in figure no.
    one.
    So that the force in the overlap zone (11) is effective and complements that exerted with the
    nut (18) pressing the area (11), a longitudinal groove has been projected on the lateral bases (22) ~
    (29) which allows a small deformation of said lateral bases (22) and in this way reinforce the union of the parts (10) and (10b) by overlapping.
    In the tubular part (10b) there are provided means that facilitate the overlapping of the parts (10) and (10b), and immobilization of both parts with "U" shaped clamps (called rods), at whose ends the one of the arms of said "U" calls embracones, threaded areas are provided for the tightening of the crossbow (10) by its overlapping zone (11) to the front axle (12), with the help of nuts (18), and plate (19), so that the clamp pressure
    (17) when tightening the nuts (28) allow said tubular part (10b) to close firmly on the other insertable part (10) in the overlapping zone (11).
    The front axle (12), in turn, has at its upper major base (23) buttresses (12.1), as can be seen, for example, in figure 1, so that the overlap zone (11) gain in rigidity thanks to these projections (12.3).
    The upper and lower bases (23 and 24) of the tubular part (10b) respectively, have been duly shaped in order to superficially present perimetral projections (20), followed by a substantially truncated conical crown (25), the projections (20) as can be seen in figure 1, they limit the longitudinal movement of the clamps (17) together with two tabs (21) as shown in figure 6, which is obtained by partial folding of the lateral bases
    (22) from the right side (10b), while at the base
    major lower (24) also of the tubular part (1 Ob), the front axle (12) is coupled supporting the vertices
    (26) of the axis (12) in the truncated conical crowns.
    According to another of the features of the invention, in order to prevent the movement of the parts (10A 10b) in the overlapping zone (11) in addition to the clamps (1 7), the assembly by the lower part of (11) is provided. ), of a plate (19) in whose four vertices (28) two holes (27) are provided, for the passage of the arms of the clamps (17) and their threaded ends, so that the entire area is tightened Overlapping (11) is achieved by the pressure of the plate (19) on the shaft (12) and, (12) in turn at the
