Definitions

  • the present invention relates to bonding of a side structure and an underframe in a car body of railway car.
  • a car body of a railway car is comprised of an underframe constituting the floor, side structures constituting the side surfaces, a roof structure constituting the roof, and end structures constituting the end portions in the longitudinal direction of the car body.
  • the underframe is comprised of two side sills arranged along the longitudinal direction of the car body, and cross beams arranged between the two side sills in perpendicular to the side sills.
  • the lower surface of the underframe is provided with bolsters, which are welded in the width direction of the car body, for mounting to a bogie. The bolsters are also welded to the side sills.
  • the bolsters are provided at two locations along the longitudinal direction of the car body.
  • the underframe and the side structures are united by welding.
  • the side structures are placed on top of the underframe, and are welded from the internal side and the external side.
  • the externally welded region is visible from the external side.
  • the thick bolsters are welded to the lower surface of the underframe. Therefore, the width size of the underframe tends to differ at different locations in the longitudinal direction. Especially, the width size greatly shrinks at the region with the bolster. For example, when the bolster is welded to the underframe, the width size of the underframe shrinks for approximately 10 mm. Therefore, the cross beam with its length elongated in prospect of this shrinkage is welded to the side sill, and then the bolster is welded thereto to obtain a predetermined size. Therefore, the welding operation of the underframe is troublesome. Moreover, the shrinkage differ from the temperature during welding operation and the like, making it difficult to manufacture an underframe with good accuracy.
  • the object of the present invention is to enable manufacturing of a high-accuracy car body with ease.
  • an upper and lower portion of a first side sill at an end portion in the width direction of an underframe and an upper and lower portions of a second side sill at an lower end portion of a side structure are respectively overlapped in the horizontal direction;
  • FIG. 1 is a longitudinal cross-sectional view of the feature according to an embodiment of the present invention.
  • FIG. 2 is a view showing the assembling operation of the underframe and the side structures according to the present invention.
  • FIG. 3 is a perspective view of the car body seen from below.
  • a car body is comprised of an underframe 10 , a pair of side structures 20 , a roof structure 30 , and end structures 40 .
  • the underframe 10 is formed by welding a plurality of hollow-shaped materials 50 , 60 that are arranged along the longitudinal direction of the car body.
  • a bolster 15 is welded to the lower surface of the underframe along the width direction thereof.
  • the bolster 15 is made of thick, plural plates.
  • the bolster 15 is also welded to the side sills at the end portions in the width direction of the underframe.
  • Each underframe 10 includes two bolsters 15 , which are provided on a bogie.
  • the hollow-shaped materials 50 , 60 are bonded together by welding or friction stir bonding.
  • the hollow-shaped material 60 constituting the end portion of the underframe 10 is comprised of two face plates 61 , 62 , and connecting plates 63 connecting the two in a truss shape. Also, to the end portion side of the hollow-shaped material 60 (end portion side of the underframe 10 in the width direction), there is provided unitarily a rigid hollow-material 65 corresponding to a so-called side sill.
  • the side sill 65 is extruded together with the hollow-shaped material 60 .
  • the region of the side sill 65 projects downward from the lower face plate 62 of the hollow-shaped material 60 .
  • the hollow-shaped material of the region is thicker than the other hollow-shaped materials (larger in the longitudinal size), and is thicker in plate thickness. Also, the same is larger in width size.
  • the bolster 15 is welded to the lower surfaces of the hollow-shaped materials 50 , 60 .
  • the end portion of the bolster 15 is welded to the side surface of the side sill 65 which projects downwardly.
  • the hollow-shaped material 50 is substantially the same as the hollow-shaped material 60 with the side sill 65 taken away.
  • the side structure 20 is comprised of a plurality of hollow-shaped materials 80 , 90 arranged along the longitudinal direction of the car body.
  • the hollow-shaped materials 80 , 90 for the general region have the same structure with the hollow-shaped materials 50 , 60 , but differ in the size and the plate thickness.
  • the lower end of the hollow-shaped material 90 at the lower end of the side structure is provided with a hollow-shaped material 95 corresponding to a so-called side sill.
  • the side sill 95 is welded to the side sill 65 , and constitutes a so-called one side sill.
  • the plate thickness at the region of the side sill 95 is thickened.
  • a projecting segment 101 is projected towards the horizontal direction from the side surface of the side sill 95 facing the underframe 65 .
  • the projecting segment 101 overlaps the upper surface of the upper face plate 71 of the side sill 65 . This overlap is fillet welded w 1 from above.
  • the upper surface of the face plate 71 at the overlap is concaved.
  • the projecting segment 101 is formed by projecting a horizontal connecting plate 105 of the hollow-shaped material 90 in the horizontal direction.
  • the side sill 65 facing the side sill 95 includes a projecting segment 73 projecting in the horizontal direction from a lower face plate 72 .
  • the face plates 71 , 72 are face plates in the horizontal direction which constitute the hollow-shaped material of the side sill 65 .
  • the projecting segment 73 overlaps the projecting segment 103 which is formed by projecting a lower plate (a connecting plate constituting the hollow-shaped material) 102 of the side sill 95 in the horizontal direction. The overlap is fillet welded w 2 from below.
  • the projecting segment 103 overlaps the projecting segment 73 from above.
  • a face plate 91 constituting the side surface of the side sill 95 is elongated downwardly to form a projecting segment 104 .
  • the projecting segment 104 is positioned at the external side of the car than the welding region, so that it makes the visual contact of the welding region from side direction (for example, from a platform) difficult. Therefore, there is no need to flatten the welding region, and the operation could be simplified.
  • the size of the overlap between the face plate 71 and the projecting segment 101 , and the size of the overlap between the projecting segment 73 and the projecting segment 103 are larger than the shrinkage of the case where a plurality of hollow-shaped materials 50 , 60 are welded together, and the maximum shrinkage of the case where the bolster 15 is welded thereto. Therefore, even if the underframe 10 shrunk at respective places, a pair of side structures 20 , 20 could be welded at predetermined intervals with ease.
  • a jig 201 with predetermined size is arranged between a pair of side structures 20 , 20 , and jigs 202 , 202 from exterior interposes the same therebetween, as is shown in FIG. 3.
  • the reference number 205 denotes a bed for placing the car body.
  • the projecting segment 73 may overlap the plate constituting the lower hollow-shaped material of the side sill 95 . That is, the projecting segment 101 may overlap the face plate 71 . Also, the projecting segment 103 may overlap the lower surface of the projecting segment 73 .
  • the side sill is indicated for each of the underframe 10 and the side structure 20 .
  • it may be formed in one body as a substantial strength member.
  • the large members positioned below the upper surface of the underframe 10 are side sills.
  • the width size of the car body could be obtained regardless of the accuracy of the width size of the underframe, the operation could be carried out with ease, and the cost could be lowered. Also, the bonding of the underframe and the side structures are performed from above and below, so that it makes it difficult to see the bonding region at the exterior of the car body from the side direction of the side structures. This results in simplified bonding operation, and cut in cost.
