Definitions

  • the subject of the present invention is a bellows for rolling stock, intended by example to ensure the connection between two cars of a mobile assembly such as a train, a tram, a bus, or any other rail or road vehicle.
  • Some known devices use a riveted configuration made of leather with like reinforcements of aluminum profiles, while others are made on the basis of a coated fabric on both sides of polyvinyl chloride (PVC), or rubber, then cut, assembled by gluing and sewing and finally reinforced on the outer contour of the waves by a bent and crimped aluminum profile.
  • PVC polyvinyl chloride
  • the problem therefore exists of providing a bellows of connection against bad weather, in particular for a railway car, ensuring watertightness and to absorb the travel between cars while maintaining a developable geometry for guarantee a good service life.
  • a general object of the present invention is to bring an advantageous solution to this problem.
  • an interconnection bellows having the features of claim 1 for rolling stock, having wavy regions forming a deformable volume, characterized in that it comprises a plurality of modules assembled together, each module being made of a material based on a elastomer such as rubber and comprising at least two wavy regions joined together by vulcanization.
  • This vulcanization assembly presents in besides the important advantage of avoiding the presence of seams which affect waterproofing on the one hand and part constitute dirt retention zones.
  • the bellows is advantageously characterized by that at least one module has at least one element of reinforcement housed inside at least one stiffener of the module, said stiffener being constituted by a frame having a larger section than the rest of the module, said stiffener being located in the extension of the outer end of at least one wavy region.
  • said stiffener connects two wavy regions of the module, when the module is not a module end.
  • Said frame may include at least one recess making it possible to house at least one said element of reinforcement.
  • Said reinforcing element is preferably a glass and resin rod, especially epoxy.
  • Said stiffener may have a surface external forming an external contour of the form module general rectangular.
  • Said stiffener may have regions substantially straight connected to each other by corner regions.
  • the reinforcement (s) are advantageously arranged only in regions substantially straight.
  • the bellows is characterized in that the modules constituting the bellows have a said frame stiffener located at each of their ends longitudinal and in that said end frames are delimited longitudinally by regions of closed outline and in that said modules are assembled between them at least one end by said frames end for example using screws so that press said contour regions against each other closed.
  • the bellows advantageously comprises a fabric or a sheet of woven rushes embedded in said material to rubber base at least in one area of the module.
  • Said closed contour regions can have complementary sawtooth profiles, to ensure a good seal.
  • the process is characterized in that the module blank has at least one stiffener forming a frame stiffener having a cross section greater than that of the rest of the blank, said stiffening frame connecting two said wavy regions, and in that at least one element of reinforcement is housed inside the stiffener frame.
  • the interconnection bellows shown in Figure 1 is a bellows 40 connecting between two cars with a number of wavy regions or waves 2 vulcanized in shape, seamless or collage.
  • each wave is in the form of an inclined frame 2 which presents in section a substantially planar section, inclined by an angle ⁇ with respect to the normal to the axis longitudinal XX 'of the bellows.
  • the edge 21 of the frame 2 which is directed towards the inside of the bellows 40 extends by a planar region 20 of closed contour which is vulcanized with the flat region 20 of wave 2 which is adjacent.
  • the module shown in Figure 1b comprises, for example, six wavy regions 2.
  • the edge 22 of the frame 2 which is directed towards the outside of the bellows 40 is extended by a stiffener exterior 3 which is common to two adjacent frames 2.
  • the stiffener 3 has a clearly marked section greater than that of regions 2, while frames 2 constitute flexible waves making it possible to ensure the displacements sought. In this way the stiffeners 3 of the bellows 40 retain their shape during deformation frames 2.
  • Said external stiffener 3 has preferably reinforcing elements 1 such as one or several epoxy glass rods which are housed in the external stiffener 3, which are for example drowned therein, in particular with adhesion to the material constituting the external reinforcement 3, or else fixed thereon, for example by being arranged in recesses provided for this purpose.
  • the external stiffener 3 forms a frame exterior of axis XX 'of generally rectangular shape outer contour 35 and having parts substantially straight 10, 12 and 14 interconnected by corner regions 11. Reinforcements 1, are of preferably arranged only in parts substantially straight 10, 12 and 14.
  • a reinforcement 1 is for example a glass rod epoxy with a diameter of 4 to 6 mm, which is manufactured conventionally from a braided glass rod which is passed through an epoxy resin bath, the resin being then polymerized.
  • the reinforcement (s) 1 according to the invention allow to overcome wave reinforcements by Aluminum of the Prior Art. Such reinforcements in aluminum which are bent and crimped, are complicated work.
  • the bellows 40 is made from modules 50 placed end to end and assembled for example by screws 6, at external end stiffeners 30.
  • the frames 2 which form the central part of the wave, the flat regions 20 and the external stiffeners 3 and 30 are made in vulcanized elastomer, for example rubber, and more particularly in vulcanized rubberized fabric, the waves 2 being joined together by vulcanization, this vulcanization ensuring mechanical cohesion and tightness at the level of the frames 2 and the stiffeners exteriors 3.
  • Each module 50 can have two end stiffeners 30 delimited longitudinally by regions of closed contour 36 allowing their assembly for example by screws 6. These regions 36 may have additional profiles 31, for example sawtooth, to ensure a seal without having a very large number of fixing screws 6 (figure 3).
  • the fixing screws 6 can thus be spaced apart for example 200 to 300 mm.
  • Wave 1 reinforcements can be combined to form a very light part, presenting a module of progressive bending according to the characterization of the rods and how they work.
  • the wave reinforcement 1 can be the support of the wave and advantageously replace the fabric on its surface to create a wave behaving like "a flat spring ".
  • the end fixing can be resumed on a stiffener 32 with dimensions larger than the stiffener 30 and which is adhered to the end frame 2 ' and drilled in 38 for fixing on the body of the car (see Figure 1b).
  • each end may consist of a metal cable fixed on the wave, outside or inside of it for secure the bellows on a profile provided for this effect.
  • the bellows 40 in its set consists of 2 or 3, even 4, 50 modules which are molded, vulcanized and which are assembled by this system where the mark 30 constitutes the molded rubber stiffener with its reinforcements glass-resin 5, the assembly consisting of modules C and D being assembled here by means of screws 6 (figure 3).
  • FIG. 1 represents a bellows 40 consisting of two modules 50.
  • the entire frame 2 can be made on the basis of a ply 7 of rushes of epoxy glass to ensure great vertical stiffness at frame 2 while retaining its possibilities of deformation.
  • This rush sheet includes for example strings of epoxy glass thread spaced one step apart example from 5 to 10 mm and joined together by weft threads to form the web 7.
  • the corner regions 11 can also be provided with a ply 7.
  • the web 7 which constitutes the reinforcement is embedded in the rubber.
  • the present invention applies also to give stiffness to the joints sealing molded or extruded.
  • the bellows according to the invention may have one end a seal 55 molded or extruded which is then adhered (or glued) to the bellows.
  • a way preferred embodiment of this joint is shown in Figure 5. It has a reinforcement region 58 in which are preferably drowned one or more reinforcing elements 8, for example one or more rods glass-resin, and a lip 9 intended to ensure sealing.
