Definitions

• the invention relates to a vehicle for the transport of automobiles and in particular to a railway vehicle.
• automobile transport vehicles comprise two platforms placed one above the other on which the automobiles to be transported take place one behind the other.
• the cross section of these transport vehicles must be within the limits of a gauge depending on the distance between the bogies. .
• the height and width of the vehicle must not, during traffic, exceed preset maximum values.
• the lower platform is located as close as possible to the reference plane that constitutes the ground, while at least locally, the so-called upper platform can take two positions:
• transport where this platform is positioned closest to the roof of the vehicles located on the lower platform and
• this upper platform is raised relative to the position of transport of sufficient value to, on the one hand, allow the movement of automobiles without risking accidental contact of their roofs with the underside of the upper platform and despite the movements due to the suspension and, on the other hand, allow the attendant responsible for placing cars on platforms to walk without having to bend.
• the ends of the lower platforms are also provided with movable ramps and gangways in order to allow cars to move from one wagon to another and to cross both the means for hooking wagons between them as tampons.
• ramps are generally articulated around a transverse axis associated with their ends opposite the platform end which they equip and their ends adjoining this platform end being raised during the loading of the cars and overshadowed during transport.
• lifting means are provided for the operation of these ramps and / or these platforms.
• the cover is split into two parts according to a median plane longitudinal to the platforms and substantially perpendicular thereto.
• These covers are, with the chassis of the vehicle, provided with maneuvering means with a view, on the one hand, to lifting the two parts of the cover and, on the other hand, to separate at least the lower edges of these two parts from cover of the aforementioned median plane.
• the devices for maneuvering and articulating the hood fractions are complex, fragile and expensive.
• the invention relates to such a transport vehicle comprising two superimposed platforms called lower and upper, a cover with a cross section substantially in the shape of an inverted U covering substantially entirely the lateral sides of the vehicle and maneuvering means. of the hood for lifting, this vehicle being characterized in that:
• the cover is in one piece and,
• the hood operating means include: means for moving and guiding in translation of the sides of the cover in a direction substantially perpendicular to the reference plane, means for synchronizing the means for moving the sides of the cover to be lifted, the said means for guiding and moving being able to move the cover over an amplitude at least equal to the distance measured between the two platforms at least when the latter are placed in the transport position.

• FIG. 2 a cross-sectional view of a transport vehicle in the car boarding configuration
• FIG. 3 a view of a detail of an embodiment of a transport vehicle.
• a vehicle 1 intended in particular for the transport of automobiles (not shown) in particular but not exclusively on the railway networks.
• This transport vehicle comprises two superimposed platforms 2, 3 called lower 2 and upper 3, a cover 4 in at least one section having a cross section substantially in the shape of an inverted U covering substantially entirely the lateral sides 5, 6 of the vehicle and means 7 for maneuvering the hood in order to lift it from a predetermined height with respect to a reference plane P such as the surface on which the vehicle travels.
• the cross section of these transport vehicles is within the limits of a template imposed by the country in which the vehicle is traveling.
• the height and width of the loaded vehicle must not exceed preset maximum values.
• the lower edges 8, 9 of the cover are preferably located substantially at the same height as the lower platform.
• the upper platform 3 and possibly the lower platform 2 are, at least locally, mobile in height and, for example, each articulated about a horizontal axis of articulation perpendicular to the longitudinal axis of the vehicle and, for its maneuver , the mobile platform is associated at least indirectly with the chassis of the vehicle by lifting means 10.
• the cover 4 is in one piece and,
• the means 7 for maneuvering the cover comprise:
• displacement means 7a and guide 7b in translation of the sides of the cover in a direction D substantially perpendicular to the reference plane P, means 11 for synchronizing the means of movement of the sides of the cover to be lifted, said means 7a, 7b of guidance and displacement being able to move the cover over an amplitude at least substantially equal to the distance measured between the two platforms 2, 3 at least when the latter are placed in the transport position.
• the cover is said to be in one piece in that it retains its initial inverted U shape and its side walls remain parallel throughout its movement.
• the cover can extend over the entire length of a platform, but it can also consist of several sections placed end to end.
• the amplitude of displacement in height of the cover is substantially equal to the distance X separating the two platforms plus an additional predetermined height Y to allow, for example, to place chocks from outside the vehicle under some of the wheels of the automobiles to be transported and, more specifically, place the chocks on the vehicles located on the specific platform.
• this additional height Y will be of the order of four hundred millimeters.
• This arrangement also makes it possible to evacuate both the exhaust gases from the lower platform and from the upper platform.
• the lower edge 8, 9 of the cover 4 has at least locally a groove which, in the lowest position of the cover, covers a rib 13 which is indirectly carried by the chassis of the vehicle.
• This arrangement ensures a good setting of the hood when the traveling vehicle is subjected to shock waves, for example, during train crossings or traffic in tunnels.
• the upper platform 3 is supported by vertical uprights 14 which, advantageously, house the means 7 for maneuvering the cover.
• the cover 4 is associated at least indirectly with the mobile parts of the platforms 2, 3 by transmission means 15, 16 in order to control the movement of the mobile parts of the platforms as a function of the movement of the cover.
• the movable part of at least the upper platform 3 is associated at least indirectly with the means of displacement 7a of the cover by means 16 of connection, which means 16 of connection control its movement synchronized with the cover 4 only at beyond a predetermined fraction of the upward path of said hood.
• the connecting means 16 comprise at least one movable stop 16a at least indirectly secured in translation of the cover over at least a fraction of its movement, which movable stop 16a cooperates with a fixed bearing surface 16b of the platform upper mobile to drive it in its rise when this mobile stop 16a has risen by a predetermined height.
• the lower platform 2 is at least locally mobile, the latter is connected to the upper platform 3 by means 17 of association interposed between a fixed point 18 of the upper platform and a fixed point 19 of the lower platform, which association means 17 allow in the first phase of the rise of the upper platform a distance thereof from the lower platform and then maintain a constant spacing between the two fixed points during the rest of the climb.
• the association means comprise at least one strap 17a, one of the ends of which is associated with the upper platform and the other end of which is provided with an elongated opening 17b in which is engaged a pin 17c carried by the lower platform.
• the means 7a for moving the cover comprises at least one screw jack 7a which drives in vertical translation, on the one hand, the cover and, on the other hand, the movable stop.
• control devices verifying the simultaneity of the movement of the cowls and which, beyond an offset of this movement, stop their movements.
• control devices are, for example, electronic devices measuring the movement of the cover and comparing the said movements between them or, more simply, two sections of electric cable of fixed length, each secured to a cover and mechanically connected by a device junction separable by traction so that, if one cover is ahead of the other by a value greater than a value fixed at least indirectly by the length of the electric cable, this causes the separation of the cable sections and electrically cuts the movement of all the covers.
• the cover is made of a light material but rigid enough not to deform during lifting.
• it is a multilayer material comprising two sheets between which is housed and in particular bonded a panel made of composite material or plastic, such as polyurethane, or else a honeycomb structure.
