    ASSEMBLY COMPRISING A WALL AND A DEFLECTOR
    The invention relates to motor vehicles.
    A motor vehicle comprises a body having a front structure defining a motor compartment, defined in particular by a front bumper, this front structure having for example a high shock absorption path and a low shock absorption pathway . The high shock absorption path comprises an upper cross member connected to the ends of two longitudinal members, via shock absorbers. In the same way, the low shock absorption pathway comprises a lower crossbar connected to the ends of two extensions, via shock absorbers. The vehicle comprises among others, within the engine compartment, a powertrain (hereinafter referenced by the acronym GMP) and a cooling system defining a front panel.
    The front bumper includes a shield (also called outer skin), this shield concealing for example a top rail and a bottom rail of shock absorption channels.
    The motor vehicle further comprises generally an air deflector, located under the front bumper, and more precisely under the shield, the deflector allowing, when the vehicle is in motion, to optimize the circulation of the air and thus reduce the drag, to the benefit of the consumption and polluting emissions of the vehicle. The deflector is generally made of polymer material.
    During assembly of the vehicle, the deflector and the shield are generally mounted on a front structure, on the same assembly station.
    Document FR 3 008 373 discloses an assembly comprising: a partition integral with a box and placed between a cooling system and a shield; a deflector comprising a body positioned under the partition; More specifically, in this assembly of the prior art, when fixing the deflector, the deflector is initially maintained laterally with respect to the body by means of two holding means, and in a second time, the deflector is attached to the shield following the attachment of the shield on the body and the release of the deflector holding means, the holding means are then removed. Each holding means has a first end adapted to be fixed on a body member and a second end adapted to be fixed on the deflector, and is in the form of a rod having at each end, a hook.
    The set just described is not without drawbacks.
    On the one hand, the attachment of the deflector on the shield and the removal of the fastening means are delicate. Indeed, the accessibility to the different fastening means and the hook of the holding means, located at the height of the deflector, cause the operator to work almost blind. The operation of fixing the deflector is even more critical when the operator must use tools such as flat keys or Allen and / or when the fixing and removal operations are performed on a vehicle whose height under hood is high, by example on a minivan, MPV or van. As a result, these operations are costly in time, to the detriment of productivity.
    In addition to the difficulties to fix the baffle on the shield and to remove the holding means, these operations impose on the operator or operators inappropriate and non-ergonomic work positions, sources of work accidents when these positions are repeated daily.
    A first objective is to provide an assembly comprising a partition integral with a body and a deflector, this assembly to optimize the time required for mounting the deflector.
    A second objective is to provide an assembly comprising a partition integral with a body and a baffle, this assembly improving ergonomics for operators during the assembly of the deflector.
    A third objective is to propose a motor vehicle comprising a set meeting the above stated objectives.
    For this purpose, it is proposed, in the first place, an assembly comprising: a partition secured to a box and placed between a cooling system and a shield; a deflector comprising a body positioned under the partition; the deflector further comprising a claw hinged relative to the body of the deflector, this claw being adapted to be introduced into an opening in the wall.
    Various additional features may be provided, alone or in combination: the partition is fixed to the cooling system; the claw comprises: a core protruding substantially perpendicularly from a flap; A wing protruding substantially perpendicularly from the core so that the core and the wing form an L; the core being adapted to come into contact with a lower edge of the opening, the wing and the flap being able to come on both sides of the partition; the wing is opposite a hole made in the shutter; the claw is movable between a rest position and an attachment position in which the wing and the flap are substantially parallel to the partition; the claw is articulated with respect to a hollow island of the body of the deflector; the claw is articulated through a hinge obtained by a reduction in the thickness of the claw; the deflector and the claw are monobloc; the assembly comprises a second integral partition of the body and placed between the cooling system and the shield, the deflector comprising a second claw articulated relative to the body of the deflector, the second claw being adapted to be introduced within a opening made in the second partition.
    It is proposed, secondly, a motor vehicle comprising a set as described above.
    Other features and advantages of the invention will appear more clearly and concretely on reading the following description of embodiments, which is made with reference to the accompanying drawings, in which: FIG. perspective view of a motor vehicle comprising an assembly having a deflector and partitions; Figure 2 is a perspective view of the attachment step of the baffle on a box and more precisely on the partitions integral with the body; Figure 3 is a perspective view, in a first orientation, of the deflector hooked on the partitions; Figure 4 is a perspective view, in a second orientation, of the deflector mounted on the partitions; Figure 5 is a perspective view of the shield attachment step on the body and the baffle hung.
    In Figure 1 is shown a vehicle 1 comprising a body 2 having a structure 3 before defining a motor compartment defined by a front bumper 4.
    One defines with respect to the vehicle 1 an orthogonal reference XYZ comprising three axes perpendicular two by two, namely: - an axis X, defining a longitudinal direction, horizontal, coincides with the general direction of movement of the vehicle 1, - a Y axis, defining a transverse direction, horizontal, which with the X axis defines a horizontal XY plane, - Z axis, defining a vertical direction, perpendicular to the horizontal XY plane.
    In the following description and with reference to the reference defined above, the terms "longitudinal" or "longitudinally" refer to a direction coincident with the X axis, the terms "transverse" or "transversely" are reference to a direction coincident with the Y axis, and the terms "vertical" or "vertically" refer to a direction coincident with the Z axis.
    The front structure 3 is delimited laterally and symmetrically by a wing, a wing liner and a wheel well (not shown).
    According to the embodiment illustrated in the figures, the front structure 3 further comprises a high shock absorption path 5 and a low shock absorption path 6.
    The high impact absorption pathway 5 comprises an upper crossmember 7 connected to the ends of two longitudinal members 8, via shock absorbers 9. In the same way, the low impact absorption pathway 6 comprises a lower crossmember 10 connected to the ends of two extensions 11, via impact absorbers 9.
    The vehicle 1 comprises, in the engine compartment, including a powertrain (hereinafter referenced by the acronym GMP and not shown in the figures) and a system 12 for cooling, defining a front panel. GMP includes a particular engine and transmission devices, to transmit the power generated by the engine to the wheels of the vehicle. The cooling system 12 comprises in particular a fan assembly (hereinafter referred to by the acronym GMV and not shown in the figures) and a radiator 13, the cooling system 12 having the primary function of cooling a cooling liquid circulating in the engine. engine. The radiator 13 is in this case mounted on a transverse support 14, this support 14 being fixed at each end to the high shock absorption path 5 via a vertical plate 15.
    The vehicle 1 further comprises an assembly 16 comprising: a partition 17 secured to the body 2 and placed between the cooling system 12 and a shield 18; a deflector 19 comprising a body 20 positioned under the partition 17.
    The deflector 19 comprises a claw 21 articulated with respect to the body 20 of the deflector 19, this claw 21 being adapted to be introduced into an opening 22 formed in the partition 17.
    More specifically, according to the example illustrated in the figures, the assembly 16 comprises two vertical partitions 17 laterally fixed on the cooling system 12, the deflector 19 comprising two claws 21, each claw 21 being able to be introduced within the opening 22 of one of the partitions 17.
    In the example shown, the shield 18 (also called outer skin and partially shown) conceals the upper crossbar 7 and the lower cross 10 of the channels 5, 6 of shock absorption. The shield 18 comprises an inlet mouth 23 in the form of a grid, adapted to let the outside air into the cooling system 12.
    According to the embodiment illustrated in the figures, the vertical partitions 17 are laterally fixed on the cooling system 12 and in other words on the front panel, these partitions 17 being also known as "anti-recycling partitions". The partitions 17 are placed between the cooling system 12 and the shield 18, and make it possible to prevent the hot air coming from the engine from entering the outside air into the cooling system 12 and adversely affect the thermal balance of the system 12 of the system. cooling. Each partition 17 matches the elements located between the shield 18 and the cooling system 12, such as the upper cross member 7 and the lower cross member 10, so that the volume in front of the cooling system 12 is isolated and so that only the air from outside, via the inlet mouth 23, enters the cooling system 12.
    Each partition 17 comprises an outer face 24 facing the absorbers 9 of the channels 5, 6 shock absorption, this outer face 24 surrounding the rectangular opening 22 located in the lower part of the partition 17. The opening 22 comprises, in a lower portion, a lower edge. The partitions 17 are for example made of polymer material.
    The air deflector 19 is located beneath the bumper 4 before and more precisely under the shield 18 and the partitions 17, this deflector 19 allowing, when the vehicle 1 is in motion, to optimize the circulation of the vehicle. air and so reduce the drag.
    According to the embodiment illustrated in the figures, the deflector 19 comprises the honeycomb body 20 and two claws 21, each claw 21 comprising on the one hand a flap 26 hinged relative to a hollow island 27 of the body 20 via a hinge 28. Each claw 21 further comprises a core 29 protruding substantially perpendicularly to the flap 26 and a flange 30 projecting substantially perpendicular to the core 29, so that the core 29 and the flange 30 form an L and that the wing 30 is facing a rectangular hole 31 of the flap 26.
    The hinge 28 connecting the island 27 and the flap 26 is obtained by a reduction of the thickness of the flap 26 near the island 27, this type of hinge 28 being known under the name "hinge film".
    Each claw 21 is movable between a hooking position (illustrated in Figures 3 and 4) in which the flange 30 and the flap 26 are opposite and substantially parallel to the outer face 24 of the partition 17, and a rest position.
    According to the embodiment illustrated in Figure 2, in the rest position, the flange 30 and the flap 26 of a claw 21 are substantially perpendicular to the outer face 24 of the partition 17.
    The claws 21 and the body 20 are monobloc and for example made of polymer material.
    According to an embodiment not shown, each claw 21 is attached to the body 20.
    When mounting a vehicle 1, the shield 18 and the deflector 19 are mounted on a vehicle 1 being assembled on the same assembly station. As represented in FIG. 2, the expression "vehicle 1 during assembly" is understood to mean a vehicle 1 comprising a body 2 (including among other things a high shock absorbing channel 5, a low shock absorption channel 6, platens 15, a support 14) on which are mounted in particular a GMP, a cooling system 12, partitions 17.
    In the following description, we will describe the various steps necessary for the attachment of a front shield 18 and a deflector 19 on a body 2 of a vehicle 1 automobile.
    The various steps can be performed by one or more operators, manually or with the aid of tools.
    Initially, the deflector 19 may be partially fixed on the structure 3 before.
    First, the operator hooks the deflector 19 on the body 2 and more specifically on the partitions 17. In fact, the operator introduces each claw 21 hinged in the opening 22 of one of the partitions 17. More precisely , the operator places each claw 21 in the hooking position, then he introduces each wing 30 within an opening 22, before descending vertically the deflector 19 so that each claw 21 is in a so-called hooked position (illustrated on Figures 3 and 4), that is to say that the partition 17 is between the core 29 and the flap 26 and that the core 29 is in contact with the lower edge 25.
    Second, the shield 18 is fixed on the body 2 and the baffle 19 hooked (shown in Figure 5).
    Following the fixing of the shield 18, the claws 21 remain in the hooked position. When using the vehicle 1, each claw 21 remains mobile with respect to the partition 17.
    The assembly 16 which has just been described offers the following advantages.
    First, the time required to mount the deflector 19 is reduced. Indeed, the attachment of the deflector 19 on the partitions 17 is permanent, the operator no longer having to remove holding devices at the end of the attachment of the deflector 19. The operator is no longer or almost no longer in the obligation to access the deflector 19 via the engine compartment to perform the mounting of the deflector 19, to the benefit of productivity and ergonomics for the operator.
    Secondly, the connection between the claw 21 and the partition 17 is a partial connection, since each claw 21 remains movable relative to the respective partition 17, this type of connection notably to avoid having high mechanical stresses. at the level of the partition 17 during an impact of the deflector 19 with for example a retarder, thus reducing the risk of breakage of the deflector 19.
    Third, with the addition of articulated claws 21 and openings 22, the assembly 16 is adaptable to any type of vehicle.
