Definitions

  • the rail vehicle is for example a non-articulated rail vehicle, that is to say a rail vehicle where the bogies are arranged under the cars, and not between the cars, at the junction between the cars.
  • WO 2015/102231 A1 describes a railway vehicle comprising a noise reduction device comprising two coupling members fixed respectively on a side wall of each of the first and second cars.
  • EP 2 106 983 A2 describes a railway vehicle comprising a frame comprising a cavity intended to receive a bogie.
  • the vehicle comprises a disturbance device arranged to modify the air flows forming in the cavity.
  • the disturbance device comprises at least one notch formed in a wall of the cavity.
  • One of the aims of the invention is to overcome this drawback by providing a rail vehicle which makes it possible to reduce the propagation of the noise generated by the bogie and the contact between the wheels and the rail inside the car.
  • the invention relates to a railway vehicle according to claim 1.
  • noise reduction devices make it possible to significantly reduce noise inside cars by reducing the propagation of acoustic waves towards the lower part of the inter-circulation device, by absorption by the noise reduction device itself and by diffraction at the level of each end of the noise canceling device.
  • the vehicle further comprises one or more of the characteristics of claims 2 to 9, taken in isolation or in any technically possible combination.
  • a railway vehicle 10 according to the invention is shown in figure 1 .
  • the rail vehicle 10 is for example a train.
  • the rail vehicle 10 comprises at least a first car 12 and a second car 14 adjacent to each other in a longitudinal direction L.
  • the first car 12 and the second car 14 have a width in a direction substantially perpendicular to the longitudinal direction.
  • Each car 12, 14 has a front end 16 and a rear end 18.
  • Each car 12, 14 comprises frame 20 and a bogie 22 fixed to the frame 20.
  • the bogie 20 is not common to the two cars 12, 14, that is to say that a bogie 22 is integral with a single car 12, 14.
  • Each bogie 20 is for example arranged in the vicinity of a of the ends of the car 12, 14.
  • each car 12, 14 comprises two bogies 22 each extending in the vicinity of one end of the car 12, 14.
  • vehicle 10 can include any number of cars 12, 14.
  • the vehicle 10 comprises at least one intercirculation device 24 connecting the front end 16 of the second car 14 to the rear end 18 of the first car 12.
  • the inter-circulation device 24 allows the passage of a passenger or a member of the crew between the first car 12 and the second car 14 and vice versa.
  • the vehicle 10 further comprises at least two noise-reduction devices 26 fixed respectively on the chassis 20 of each of the cars 12, 14, between the bogie 22 of each of the cars 12, 14 and the inter-circulation device 24.
  • the noise-canceling devices 26 are respectively fixed on the rear end 18 of the first car 12 and the front end 16 of the second car 14 under the floor of the car 12, 14, i.e. next to the rails on which the rail vehicle travels 10.
  • the anti-noise devices 26 extend mainly in a direction substantially perpendicular to the longitudinal direction.
  • At least one of the noise-reduction devices 26 comprises a face 28 extending substantially in a plane of the rear end 18 of the first car 12 or in a plane of the front end 16 of the second car 14, these planes s' extending along the direction of elevation and along the width of the rail vehicle 10.
  • the noise reduction devices 26 extend over the entire width of the first and second cars 12, 14.
  • Each noise reduction device 26 has a dimension in an elevation direction of between 30 cm and 60 cm, for example 50 cm.
  • the noise reduction device 26 comprises a first face 30 fixed to the chassis 20 of the car 12, 14 and a second face 32 substantially perpendicular to the first face 30.
  • the noise reduction device 26 is a straight prism with a trapezoidal base. More particularly, the base is a rectangular trapezoid.
  • the noise-reduction device 26 comprises a third face 34 substantially perpendicular to the second face 32 and substantially parallel to the first face 30.
  • the noise-reduction device 26 further comprises a fourth face 36 bevelled facing the second face 32, oriented towards the front. bogie 22. In other words, the fourth face 36 is not perpendicular to the first face 30 and to the third face 34.
  • the noise-reduction device 26 is a prism with a triangular base.
  • a section of the noise reduction device 26 in a longitudinal plane is a right triangle. The hypotenuse of the right triangle being oriented towards the bogie 22 of the corresponding car 12, 14.
  • the noise reduction device 26 has a different shape, guided for example by the maintenance requirements of the rail vehicle 10 or aerodynamic considerations.
  • the noise-reduction device 26 comprises for example a rigid element, for example made of steel to minimize costs and guarantee good mechanical performance.
  • the noise reduction device 26 comprises a layer of sound absorption material fixed to the rigid element, in order to further improve the noise absorption performance.
  • the absorbent material is, for example, closed cell foam.
  • the thickness of the layer of absorbent material is 50 mm.
  • the rail vehicle 10 according to the invention is particularly advantageous because it makes it possible to significantly reduce the noise inside the coaches 12, 14 by reducing the noise at the level of the intercirculation device 24 by 5 to 25 dB, the reductions maximum noise being obtained with noise reduction devices 26 comprising a layer of absorbent material on their surface.
  • noise reduction devices 26 comprising a layer of absorbent material on their surface.
