Definitions

  • the present invention relates to a car body structure having a body bolster and a center sill intersecting therewith arranged under a floor of the car body, and further having wires and pipes laid under the floor.
  • the car body is composed of side structures, end structures, a roof structure and an underframe structure.
  • Underframe On both longitudinal car body ends on the lower surface of the floor structure (hereinafter referred to as underframe) are provided center sills having couplers for connecting adjacent cars and body bolsters for supporting the weight of the car body via bogies.
  • a car body structure is adopted in which the center sills and body bolsters provided at both longitudinal car body ends of the underframe are combined to provide sufficient strength to bear the heavy load acting on the car body via the couplers attached to the center sill, in order to bear the car-end compressive load mentioned earlier.
  • Japanese Utility Model Publication No. 57-56929 discloses an example of a car body structure in which a center sill is welded to a lower surface of hollow extrusions. Further, the present applicant proposes in Japanese patent No. 3624527 (patent document 2) an underframe manufacturing method which enables to manufacture an underframe composed of a plurality of shape members efficiently. Moreover, another structural example in which a body bolster is welded to a lower surface of hollow extrusions is disclosed in page 308 of the above-mentioned non-patent document 1.
  • FIGS. 8 and 9 illustrate one example of a prior art car body structure.
  • FIG. 8 is a bottom view of a conventional car body structure
  • FIG. 9 is a cross-sectional view taken at D-D of the car body structure of FIG. 8 .
  • the illustrated car body structure has two center sills 47, 47 aligned side by side in the width direction of the car body.
  • reference 2 denotes the floor
  • reference 3 denotes side sills
  • reference 4 denotes end sills
  • reference 6 denotes air spring supports
  • reference 9 denotes antirolling device supports 9 provided on the body bolster 45.
  • wires and pipes On the lower surface of the floor 2 of the underframe 41 are disposed wires and pipes extending in the longitudinal direction of the car body connecting the ends of the car body and the center of the car body, and the wires and pipes must be passed through the body bolster 45 arranged to extend in the width direction of the car body so as not to take up much space in the height direction of the car body by being arranged in a straight line.
  • the wires and pipes are arranged through penetration pipes 50 disposed independently in the body bolster 45.
  • body bolsters 45 having antirolling device supports 9 must have high rigidity and high strength. Thus, it is not preferable to form openings on the body bolster 45, but by forming penetration pipes 50, the rigidity and strength of the body bolster 45 is deteriorated.
  • the rigidity of the body bolster 45 tends to be reduced as the number of penetration pipes 50 increases, and the strength of the body bolster 45 deteriorates greatly as the position of penetration pipes 50 approximates the antirolling device supports 9.
  • Various reinforcement members are disposed to ensure the rigidity and strength of the body bolster 45, but the prior art method of providing reinforcement members increases the number of components and welding locations, complicates the underfloor structure, takes up much underfloor height and increases the manufacturing costs of the car body.
  • FIGS. 10 and 11 illustrate another example of a prior art car body structure.
  • FIG. 10 is a bottom view of a car body structure of this example
  • FIG. 11 is a cross-sectional view taken at G-G of the car body structure of FIG. 10 .
  • the same components as those illustrated in FIGS. 8 and 9 are provided with the same reference numbers.
  • This prior art car body structure has an underframe 51 in which a single center sill 57 is disposed in the center of width of the car body intersecting with the body bolster 55.
  • the body bolster 55 has penetration pipes 60 passing therethrough arranged on both sides of the center sill 57 for allowing wires and pipes to be passed through.
  • US-2 946 297 and GB-849 226 show railway cars in which conduits for wires and pipes intersect body bolsters.
  • the object of the present invention is to provide a car body structure having various equipments and wires or pipes for connecting the same arranged under the floor of a car body, capable of solving the problem of the car body structure including the increase of the number of components, complication of the underfloor structure and increase of the manufacturing costs of the car body, and capable of facilitating the laying process of wires and pipes through a body bolster without deteriorating the rigidity of the body bolster.
  • the present invention provides a car body structure as set out in claim 1.
  • the center sill is penetrated through the body bolster, the intersecting portion of the center sill forming a penetration portion, and the interior of the penetration portion is used to pass wires and pipes therethrough, so that the conventional penetration pipes dedicated for passing wires and pipes are no longer necessary, and the prior art problem of deterioration of rigidity and strength of the body bolster caused by the formation of voids for passing the dedicated penetration pipes in the body bolster can be solved.
  • a penetration portion effective for simplifying the underfloor structure related to the arrangement of wires and pipes is provided using a strength member (center sill) constituting the major structure of the underframe, so that it is no longer necessary to provide through pipes dedicated for passing wires and pipes through the body bolster. Therefore, the present invention enables to maintain the rigidity and strength of the underfloor structure, especially the body bolster, of the car body, facilitate the laying operation of wires and pipes through the body bolster, prevent increase of components of the underfloor structure and complication of the underfloor structure, and reduce the manufacturing costs of the car body.

  • an underframe 1 is composed of a floor 2 formed by arranging a plurality of panel members side by side in a plane and joining the same together, side sills 3 disposed on both side ends of the floor 2 in the width direction of the car body, end sills 4 disposed on both longitudinal ends of the floor 2, and a body bolster 5 and center sills 7 disposed on the lower surface of the floor 2.
  • the floor 2 is formed by arranging panel members formed of a plurality of hollow extrusions in a plane so that their longitudinal direction corresponds to the longitudinal direction of the car body, and joining the side ends of adjacent plate members together.
  • the floor 2 is joined by welding the upper and lower surfaces, or both sides, of adjacent panel members.

  • the end sills 4 are arranged to extend longitudinally along the longitudinal ends of the floor 2.
  • the end sills 4 are formed of hollow extrusions.
  • the body bolster 5 is attached to the lower surface of the floor 2 near the longitudinal center area of the car body at a given distance from the end sill 4.
  • the body bolster 5 is disposed at a position where the car body is supported by the bogie, and is arranged to extend across the whole length of the width direction of the car body between the both side sills 3, 3.
  • the body bolster 5 has a given width in the longitudinal direction of the car body, and on both ends thereof are arranged air spring supports 6, 6.
  • the weight of the car body is supported by a bogie via air springs (not shown) of the bogie at positions corresponding to the air spring supports 6, 6 provided on the body bolster 5 on the lower surface of the floor 2.
  • Two center sills 7, 7 are disposed to extend in the longitudinal direction of the car body symmetrically with respect to the center line of width of the car body between the end sills 4 and body bolsters 3.
  • Each center sill 7 is formed of a hollow extrusion having a rectangular cross-section and a hollow interior.
  • a coupler support 8 On the end of the center sills 7, 7 corresponding to the longitudinal direction of the car body is disposed a coupler support 8 for attaching a coupler (not shown) for connecting the car with an adjacent car.
  • the other end of the center sills 7, 7 disposed near the center in the longitudinal direction of the car body intersects with and is attached to the body bolster 5.
  • the body bolster 5 has antirolling device supports 9, 9 for fixing an antirolling device (not shown) for suppressing rolling of the car body disposed in the space near the air spring supports 6, 6, that is, in this example, in the space between the air spring supports 6, 6 and the center sills 7, 7.
