Definitions

  • the present invention relates to a car body structure of a vehicle, in particular a railway vehicle.
  • the name “gooseneck” comes from the shape of the part which has a substantially vertical part and a part inclined with respect to the vertical part, and having a rounded cutout in the vicinity of a bogie of the vehicle, and a cutout substantially rectangular with rounded edges in the vicinity of a vehicle door.
  • the subject of the present invention is a car body structure for a vehicle, in particular a railway vehicle, comprising at least two structural parts arranged transversely on either side of the body structure, in which each structural part has a substantially vertical and a part inclined with respect to the vertical part, and comprises at least two sections assembled and made of aluminum or composite material, the body structure comprising a transverse joining beam fixed to each of the two structural parts, the transverse junction being made of steel or composite material.
  • the structural parts and the connecting beam are simple to produce, and the whole is reinforced in such a way. so that the body structure is resistant to high stresses.
  • the invention also relates to a vehicle coach, in particular a railway car, comprising a body structure as described above.
  • FIG. 1 On the figure 1 , there is shown a car 10 of the vehicle.
  • the vehicle is for example a railway vehicle.
  • the vehicle is a bus.
  • Car 10 includes body 12.
  • the body 12 comprises a frame 13.
  • the car 10 comprises at least one door 14 intended for the boarding or alighting of passengers or personnel on board the car 10.
  • Car 10 includes at least one bogie 16 in the vicinity of door 12.
  • Body 12 includes body structure 18.
  • the body structure 18 notably comprises two structural parts 20, 21 arranged transversely on either side of the body structure and a transverse junction beam 22 fixed to each of the two structural parts 20, 21 as can be seen on the picture 3 .
  • Each structural part 20, 21, one of which is shown in the figure 2 has a substantially vertical part and a part inclined with respect to the vertical part and comprises at least two sections 24, 26, 28 assembled as will be described in more detail below.
  • Each structural part 20, 21 is for example intended to be placed between a bogie 16 and a door 12 of the rail vehicle car.
  • the sections 24, 26, 28 are made of aluminum or composite material. Preferably, the sections 24, 26, 28 are made of aluminum.
  • the structural part 20, 21 is therefore light and does not weigh down the car 10.
  • the sections 24, 26, 28 are for example assembled to each other by welding.
  • each structural part 20, 21 comprises three sections 24, 26, 28 assembled.
  • a first section 24 forms an upper part of the structural part 20, 21.
  • the first profile 24 has for example a substantially rectangular shape, the two long sides of which extend substantially along the longitudinal direction L defined with respect to a normal direction of movement of a vehicle.
  • the first profile 24, and in particular the two long sides of the first profile 24, extends between a front end edge 30 and a rear end edge 32.
  • a second section 26 forms a lower part of the structural part 20, 21.
  • the second profile 26 comprises for example three portions 34, 36, 38 comprising a first upper portion 34, a second intermediate portion 36 and a third lower portion 38.
  • the first upper portion 34 advantageously extends in the same plane as the first section 24.
  • the second intermediate portion 36 advantageously extends between the first portion 34 and the third portion 38.
  • the second intermediate portion 36 advantageously forms an obtuse angle with the first portion 34.
  • the third lower portion 38 extends from the second intermediate portion 36.
  • the third lower portion 38 advantageously forms an obtuse angle with the second intermediate portion 36 so that the three portions 34, 36, 38 substantially form a flared U.
  • a third profile 28 called connecting profile extends between the first profile 24 and the second profile 26.
  • the connecting profile 28 extends in the same plane as the first profile 24 and the first upper portion 30 of the second profile 26.
  • the connecting section 28 has, for example, a front edge 40 cut in the shape of a half-parabola, and a rear edge 42 straight.
  • the top of the half-parabola is located in the upper part of the third section 28.
  • the semi-parabolic shape makes it possible in particular to frame the bogie 16 located under the structural part 20, 21 when the latter is in place on a carriage 10 of a railway vehicle.
  • the rear edge 42 extends in the extension of the rear end edge 32 of the first profile 24.
  • the second section 26 extends between a front end edge 44 and a rear end edge 46.
  • the front end edge 44 of the second section 26 is straight and extends in the extension of the front end edge 40 of the connecting section 28.
  • the rear end edge 46 of the second profile 26 advantageously first extends in the extension of the rear end edge 42 of the connecting profile 28 then forms an angle so that the rear end edge 46 of the second profile 26 delimits part of a door passage 14.
  • the angle formed is substantially straight and has rounded edges.
  • the two structural parts 20, 21 are symmetrical with respect to a plane.
  • the two structural parts 20, 21 are symmetrical with respect to a median longitudinal plane P, said plane P separating the car 10 into a left half and a right half.
  • the two structural parts 20, 21 are joined together by a joining beam 22.
  • the transverse junction beam 22, visible on the Figure 3 is made of steel or composite material.
  • the transverse joining beam 22 is made of steel.
  • the transverse joining beam 22 thus contributes to reinforcing the two structural parts 20, 21 which are made of aluminium.
  • the transverse junction beam 22 is arranged transversely between the two structural parts 20, 21 and extends between two ends 50, 52.
  • Each end 50, 52 of the transverse junction beam 22 rests on two adjacent sections 26, 28 of a structural part 20, 21.
  • each end 50, 52 of the transverse junction beam 22 rests on the second lower section 26 and on the connecting section 28.
  • each end 50, 52 of the transverse junction beam 22 has a shape complementary to the shape of the two sections 26, 28 on which it rests.
  • the transverse joining beam 22 is fixed to each structural part 20, 21 by riveting.
  • the transverse junction beam 22 is for example manufactured using an assembly jig.
  • the connecting beams 22 produced from the same template will therefore have identical dimensions, facilitating compliance with body width standards.
  • the body structure 18 thus makes it possible to lighten the body 12 by proposing structural parts 20, 21 in aluminium, while guaranteeing optimum rigidity with the aid of the transverse joining beam 22.
  • the structural parts 20, 21 are placed facing each other symmetrically with respect to the median longitudinal plane P, said plane P separating the car 10 into a left half and a right half.
  • the transverse junction beam 22 is assembled to the structural parts 20, 21 transversely to the plane P, preferably by riveting.
  • the frame 13 comprises a low transverse crosspiece 60.
  • the transverse lower crosspiece 60 is assembled, for example, at the same time as the transverse joining beam 22.
