Definitions

  • the present invention relates to a car body structure comprising a body bolster and a centre sill intersecting therewith on an underframe, and is especially applicable to such a structure in a railway vehicle.
  • the present invention relates to a car body structure having wires and pipes laid under the floor of the car body.
  • the car body is composed of side structures, end structures, a roof structure and an underframe.
  • the underframe is composed of end sills disposed at both longitudinal car ends, a centre sills connected to the end sills and having couplers for connecting adjacent cars, a body bolster for providing connection with a bogie which is a travelling device of the railway car, a floor capable of having seats and the like arranged thereon, and side sills disposed on both width-direction ends of the car.
  • a car body structure is formed by combining the centre sills and body bolsters provided at both longitudinal car body ends of the underframe so as to have sufficient strength to bear the heavy load acting on the car body via the couplers attached to the centre sill.
  • Japanese Utility Model Examined Publication No. 57-56929 discloses an example of a car body structure in which a centre sill is welded to a lower face plate of a hollow extruded shape member. Further, the present applicant proposes in Japanese patent No. 3624527 (patent document 2) an underframe manufacturing method which enables to efficiently manufacture an underframe composed of a plurality of shape members. Moreover, another example of a car body structure in which a body bolster is welded to a lower surface of the hollow extruded shape member is disclosed on page 308 of the above-mentioned non-patent document 1.
  • various equipments such as power systems, control systems and high-pressure air systems are disposed in a crushed state under the floor of railway vehicles.
  • wires and pipes connected to these equipments are arranged under the floor of the car body, but especially in the area near the bogie, it is difficult to ensure sufficient space for arranging these wires and pipes.
  • Penetration pipes for collectively arranging wires and pipes are efficient means for simplifying the underfloor structure.
  • penetration pipes are disposed in body bolsters to enable wires and pipes to be laid therethrough, but such arrangement lacks to consider any solution to drawbacks such as the deterioration of strength of the body bolsters and increase in the number of components.
  • FIGS. 14 through 16 illustrate one example of a prior art car body structure.
  • FIG. 14 is a bottom view of a prior art car body structure
  • FIGS. 15 and 16 are cross-sectional views taken at E-E and F-F of the car body structure of FIG. 14 .
  • the illustrated car body structure has two centre sills 7 and 7 arranged side by side in the width direction of the car body.

  • reference 6 denotes air spring supports
  • reference 8 denotes coupler supports
  • reference 9 denotes antirolling device supports.
  • a centre pin support 20 is disposed on the lower surface of the body bolster 5.

  • On the lower surface of the floor 2 of the underframe 1 are arranged wires and pipes 11 extending in the longitudinal direction of the car body connecting the ends of the car body and the centre of the car body, and the wires and pipes 11 must be passed through the body bolster 5 extending 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 11 are arranged to pass through penetration pipes 15 disposed independently in the body bolster 5.
  • the body bolster 5 having antirolling device supports 9 receiving large load from the antirolling device must have high rigidity and high strength.
  • the rigidity and strength of the body bolster 5 is deteriorated.
  • the rigidity of the body bolster 5 is further deteriorated as the number of penetration pipes 15 increases, and the strength of the body bolster 5 is deteriorated greatly as the position of penetration pipes 15 becomes closer to the antirolling device supports 9.
  • Various reinforcement members must be disposed to ensure the rigidity and strength of the body bolster 5 to compensate for the deterioration of rigidity and strength of the body bolster 5 by disposing penetration pipes 15, which increases the number of components, complicates the underfloor structure, takes up much underfloor height and raises the manufacturing costs of the car body.
