Definitions

  • the invention relates to the floating assembly of internal floors of various vehicles, for example naval, rail or road vehicles. It relates more particularly to elastic connecting elements damping vibrations and noise that allow to suspend an internal floor structure on the frame of the body / structure of a vehicle and which we will subsequently designate "chassis structure" . To illustrate this invention, we have described elastic connection elements for the floating mounting of internal floors on the chassis of the boiler of railway vehicles.
  • connection elements particularly effective in terms of damping vibrations and noise and which are currently used at present, particularly for the floating installation of internal floors on the floors of the cauldrons of railway vehicles.
  • These elastic connection elements comprise a lower element having a first support wall intended to be fixed on the floor of the chassis structure, an upper element having a second support wall, substantially parallel to said first support wall and intended to be fixed on said inner floor and an elastic mass arranged between said lower element and said upper element so that said lower element and said upper element can make limited movements relative to each other, mainly according to the direction perpendicular to said support walls but also longitudinally and transversely, while remaining distant from one another.
  • connection elements In practice, one installs, leveling and individually fixed, by gluing, screwing, riveting or welding, said elastic connection elements on the floor of the chassis structure and then the elements of the internal floor are placed on said elements of elastic connection, which we will call later "connecting elements".
  • connecting elements typically (the number and distribution of connecting elements depends on the load to be supported), it is necessary to fix 4 to 6 connecting elements per square meter, that is to say of the order of 200 to 300 elements. caulking connection.
  • the time spent preparing the floor of the chassis structure before the placement of the floor elements is of the order of 5-12 h.
  • the connecting elements are fragile obstacles that operators must avoid when moving, so that the intervention devoted to the floating assembly of such floors has been up to now considered particularly long and delicate.
  • the floor elements constituting the internal floor are then assembled and fixed, typically by screwing, on the upper elements of the elements. connection, for example using self-tapping screws.
  • each connecting element is controlled and adjusted in height before the installation and fixing of the floor element, to take into account local height differences resulting from the imperfect flatness of the floor of the chassis structure.
  • European patent EP 0 774 400 has a connecting element whose structure is very close to that of EP 0 576 394 with a lower element, an upper element and an elastic mass arranged between the lower element and the upper element.
  • a connecting element whose structure is very close to that of EP 0 576 394 with a lower element, an upper element and an elastic mass arranged between the lower element and the upper element.
  • the utility model German DE7518155U discloses an elastic connecting element comprising an upper element and a lower element separated by an elastic structure, the lower element itself being subdivided into two parts that can be displaced relative to each other: a flange connected to the elastic structure and a base, the gap between these two parts can be adjusted through a screw-nut system.
  • the applicant has therefore tried to find a satisfactory solution for the floating assembly of an internal floor on the floor of the chassis structure of any vehicle, for example the cauldron of a railway vehicle, resulting in duration of intervention as short as possible, the internal floor must also have a perfect flatness, independent of flatness defects of the floor of the frame structure.
  • one of the two elements separated by the elastic mass (the lower element or the upper element) of the connecting element according to the invention is itself subdivided into at least two mutually integral but movable parts; one in relation to the other in a direction substantially perpendicular to the support walls.
  • Said first piece and said second piece are interconnected by a mechanical connection, called "incomplete”, which has at least one degree of freedom, in that it allows said first piece and said second piece to move. one with respect to the other in a direction substantially perpendicular to said first and second support walls.
  • the connecting element according to the invention differs from DE 75 18 155U in that, by acting on the connection element itself, that is to say by imposing a relative displacement of the first part relative to the second part, it is possible to compensate for the height differences related to the lack of flatness the floor of the chassis structure without the need to pre-equip the floor of the frame structure with elements foreign to the connecting element. So, there is no need, as in EP 0 774 400 or DE 75 18 155U , to fix bases on the floor of the frame structure to receive said connecting elements and to allow their height adjustment.
  • the great advantage of the invention lies in the possibility of pre-equipping the internal floor panels with said connecting elements so that at the time of assembly of the internal floor, there is no waste of time in the preparation of the floor of the chassis structure, which, without prefixed connecting pieces, remains easy to access and can be pushed by the operators without any particular precautions.

  • the following examples show that it is also possible to subdivide the upper element into two parts integral and movable relative to each other.
  • said first piece and said second piece are interconnected by an incomplete mechanical connection, which allows the relative displacement of one piece relative to the other in a direction substantially perpendicular to the support walls.
  • This incomplete mechanical connection is for example a slide connection which provides 5 degrees of connection and allows only a translational movement in the intended direction.
  • This can be a sliding pivot connection with anti-rotation (typically a cylindrical shaft sliding in a bore without rotating about its axis, a helical connection (typically a screw-nut system), or a connection "double plane support” with secant contact planes (typically a system of wedges sliding support).
  • Relative movement of the first piece relative to the second piece can be directly imposed manually. It can also be achieved using an intermediate piece whose displacement causes the relative movement of the first piece relative to the second piece.
  • This intermediate part may be either part of a screw-nut system, one or more translational corners, the body or rod of a cylinder.
  • the spacer can be moved by hand or with the aid of an actuator powered by an auxiliary energy source, such as a compressed spring, an electromechanical, pneumatic or hydraulic cylinder or a deformable enclosure pressurized with air to be used as a pneumatic support.
  • auxiliary energy makes it possible to automate and / or remotely control the movement of the first piece relative to the second piece to reach the gap referred to, for example to allow the leveling of the floor element.
  • said displacement can be performed after the laying of the floor element, even if access to the spacer or to the actuator is not very easy.

  • the connecting element comprises, in addition to the elastic mass formed between the upper element and the lower element, an outer layer which is adjacent to the second support wall and which is made of an insulating and elastic material, insulation to prevent possible stack corrosion between the material of the second support wall and the material of the underside of the inner floor panel, resilient to improve the damping of vibration and noise.

They can also be simply held temporarily secured to the internal floor panel, for example by cooperation of securing means temporary (snap-fastening or screwing means, or reversible force sinking means, typically a male portion of the upper member to be driven into a cavity in said inner floor panel). Once the internal floor panel has been placed on the chassis-frame floor, these temporary securing means are removed in order to allow the activation of a spacer and the setting and freezing of the gap between the first part and the second room.
