Definitions

  • the present invention relates to a rail vehicle body and a rail vehicle with improved crashworthiness.
  • Crashworthiness standards for railway vehicle bodies define a series of collision scenarios and identify common methods of providing passive safety that may be adopted to suit individual vehicle requirements.
  • European Standard EN 15227:2008+A1:2010 also specifies the characteristics of reference obstacles for use in the design collision scenarios. Some of the scenarios deal with rigid or massive obstacles and others with deformable obstacles, leading to potentially conflicting optimisation strategies.
  • a rail vehicle comprising a rigid chassis extending under the driver's cab is known from EP 1 215 098 A1 . It comprises a protection shield, located in front of the cab, provided with a rigid structure. The shield rests on the chassis and is connected to the chassis by an energy absorbing element interposed between the shield and the chassis.
  • the invention aims to provide improved response to a collision scenario dealing with a deformable obstacle without negatively impacting the response to a collision scenario dealing with an identical train unit.
  • a rail vehicle body having a longitudinal vertical median plane and comprising:
  • the non-deformable obstacle-removing rams provide means for removing a deformable obstacle without deforming the end structure of the rail vehicle body.
  • the corresponding free spaces ensure that in a collision scenario involving an identical train unit, the non-deformable obstacle-removing rams will not collide first with the obstacle.
  • the terms "non-deformable" with reference to the non-deformable obstacle-removing rams shall mean that the rams are able to withstand without plastic deformation an impact with the specific deformable obstacle defined in the European Standard EN 15227:2008+A1:2010 in the conditions specified in the Standard.
  • the rams are able to withstand without plastic deformation an impact with an obstacle which has the following characteristics: a mass of 15 000 kg, a centre of mass at 1 750 mm above rail level, no friction to the ground and a stiffness of less than 6430 kN/mm.
  • each of the free spaces has a width measured perpendicularly to the longitudinal vertical median plane, which is greater than a width of the symmetric image of the corresponding non-deformable obstacle-removing ram, preferably with a transverse clearance greater than 100mm, most preferably greater than 200mm.
  • the transverse clearance will compensate potential misalignments between two identical colliding rail vehicles on a straight track. Such misalignment may result, in particular, from the lateral clearance between the car body and the running gear and from the lateral clearance between the wheels and the track.
  • the non-deformable structural framework includes a set of non-deformable beams extending in the vertical transversal reference plane and supporting the set of one or more non-deformable obstacle-removing rams
  • the set of non-deformable beams preferably includes a transverse beam and one or more vertical beams extending between a subframe of the non-deformable structural framework and the transverse beam, each of the one or more vertical beams supporting one of the non-deformable obstacle-removing rams.
  • each of the one or more non-deformable obstacle-removing rams has a slanted shape.
  • a set of shock absorbing elements in a non-deformed state which protrudes from the vertical transversal reference plane in the longitudinal forward direction at a vertical distance Z below the set of one or more non-deformable obstacle-removing rams, wherein the shock absorbing elements are deformable in a deformed state upon impact with an obstacle.
  • the shock-absorbing elements will be the first to collide with the obstacle.
  • the shock-absorbing elements should preferably not be involved in the collision scenario against the deformable obstacle and should therefore preferably be at a substantial distance below the non-deformable obstacle-removing rams.
  • the vertical distance Z is more than 400 mm, preferably more than 500 mm, most preferably more than 600 mm.
  • the shock absorbing elements have a front end which, in the deformed state of the shock absorbing elements, is tangent to a rearward vertical transverse plane, which is in front of, or coplanar with, the vertical transversal reference plane.
  • the shock-absorbing elements should preferably be dimensioned such as to absorb a significant part of the collision energy in the collision scenario with an identical train.
  • the non-deformable obstacle removing rams should preferably be dimensioned such that, in a collision scenario with a 80t wagon provided with elastomeric buffers as defined in the European Standard EN 15227:2008+A1:2010, they never contact the obstacle. Therefore, the shock absorbing elements have a front end which, in the non-deformed state of the shock absorbing elements, is at a predetermined distance Y1 in front of the vertical transversal reference plane, and Y 1 ⁇ 105 ⁇ mm
  • the non-deformable obstacle removing rams should preferably be dimensioned such that they contact and possibly remove the deformable obstacle before it reaches the shock-absorbing elements.
  • the forward end of the obstacle-removing rams is located at a predetermined distance Y 2 from the vertical transversal reference plane, and Y 1 ⁇ Y 2 ⁇ 350 ⁇ mm
  • a rail vehicle comprising the rail vehicle body as described hereinbefore and a set of running gears for carrying and guiding the rail vehicle body along a track, wherein the running gears define a track level, wherein the set of one or more non-deformable obstacle-removing rams protrudes from the vertical transversal reference plane in the longitudinal forward direction at a predetermined height Z 2 above the track level and the set of shock absorbing elements protrudes from the vertical transversal reference plane in the longitudinal forward direction at a predetermined height Z 1 above the track level, wherein: ⁇ 1,2 ⁇ m ⁇ Z 2 Z 1 ⁇ 1,2 ⁇ m
  • the obstacle-removing rams are specifically located at a height that will collide with a deformable obstacle, whereas the shock absorbing elements are located below the deformable part of the obstacle.
  • a rail vehicle comprising the rail vehicle body as described hereinbefore and a set of running gears for carrying and guiding the rail vehicle body along a track, in particular a rail vehicle as described hereinbefore, wherein the running gears are such that the vehicle body has a given lateral clearance relative to a mid-path defined by the track in a transverse direction perpendicular to the longitudinal vertical median plane, and each of the free spaces has a location and dimensions such as to contain a second image of the corresponding non-deformable obstacle-removing ram which results from a translation of the symmetric image in the transverse direction with an amplitude equal to the lateral clearance.
  • an end structure 10 of a vehicle body 12 of a rail vehicle 14 comprises a non-deformable structural framework 16 defining a vertical transversal reference plane 100 of the rail vehicle body 12 perpendicular to a longitudinal forward direction 200, and to a longitudinal vertical median plane 300 of the vehicle body 12.

  • the longitudinal vertical median plane 300 is not a plane of symmetry for the vertical beams 24, 26, i.e. the vertical beam 24 on one side of the longitudinal vertical median plane is not at the same distance from the plane 300 as the vertical beam 26 on the other side.
  • the rail vehicle body 12 further comprises a set of shock absorbing elements 34, 36 protruding from the vertical transversal reference plane 100 in the longitudinal forward direction 200.

  • the rail vehicle 14 comprises a set of running gears 38 for carrying and guiding the rail vehicle body 12 along a track 40.
  • the running gears 38 define a track level 400, and the set of shock absorbing elements are at a predetermined height Z 1 above the track level 400.

  • the rail vehicle body 12 further comprises a set of two non-deformable obstacle-removing rams 42, 44 integral with the non-deformable structural framework 16 and protruding from the vertical transversal reference plane 100 in the longitudinal forward direction 200.

  • the non-deformable obstacle-removing rams 42, 44 protrude from the vertical transversal reference plane 100 in the longitudinal forward direction 200 at a predetermined height Zz above the track level and above the shock absorbing elements 36, 38, such that: 1,20 ⁇ m ⁇ Z 2
  • the height Z 2 is such that: 1,70 ⁇ m ⁇ Z 2 ⁇ 2,20 ⁇ m
