Definitions

  • the present invention relates to a car structure forming a rail vehicle such as a railroad vehicle or a monorail car, and in particular relates to a car structure configured by jointing hollow members made of aluminum alloy, for example.
  • a car structure comprises a roof component forming an upper side, two side structures forming lateral sides, an underframe forming a lower side, and two end components forming end sides in a longitudinal direction.
  • Patent Document 1 Japanese Patent Publication No. 2604226
  • an entrance provided in the side structure of the car structure is formed by providing an opening in the hollow member of the side structure and welding an entrance frame having a large thickness to the opening for reinforcing.
  • Patent Document 2 Japanese Patent Publication No. 3751236
  • a rail car structure is subjected to vertical static load due to passengers on the vehicle or dynamic load caused by vertical vibration or the like generated when the vehicle runs on rails. Therefore, it is necessary that the rail car structure has the required strength against these loads.
  • Parts in the structure which may be in a severe condition in terms of strength due to these loads are two side structures which entirely bear these loads.
  • static or dynamic deformation occurs in a concentrated manner around an entrance of the side structure where a large opening is formed for passengers getting on or off and therefore this area is in the most severe condition in terms of strength.
  • a robust frame is generally provided around the entrance of the side structure. The technical cause of this severe condition in terms of strength will be described again hereinafter with reference to FIG. 3 .
  • Coupling of the entrance frame and the side structure is accomplished by extending a face plate of the hollow member forming the side structure towards the entrance frame and placing the face plate on a seat provided in the entrance frame and butt welding a tip of the face plate thereto.
  • deformation due to vertical load is concentrated and high stress is generated on the face plate which is sandwiched between the robust hollow member and entrance frame. If plate thickness of the face plate of the hollow member is increased as a whole in order to prevent this, the weight of the structure is significantly increased accordingly.
  • a car structure comprising a side structure formed by a hollow member consisting of a vehicle outer face plate, a vehicle inner face plate, and a plurality of ribs coupling both face plates, the side structure comprising an entrance opened therein, in which an entrance frame is fixed to the vehicle outer face plate and the vehicle inner face plate of the hollow member along an opening edge of the entrance, wherein the vehicle outer face plate and the vehicle inner face plate are welded by a joint member along the opening edge, and the joint member consists of a first joint part which couples the vehicle outer face plate and the vehicle inner face plate and a second joint part which couples a part of the first joint part near the vehicle outer face plate and a vehicle outer side of the entrance frame.
  • a car structure having the required strength against vertical load can be provided while avoiding increase in weight of the structure.
  • two face plates of the hollow member are coupled by the first joint part so that they can withstand the vertical load. Therefore, two face plates may be thin and thereby the side structure can be light in weight.
  • FIG. 1 is a perspective view of a rail car structure of one embodiment of the present invention
  • FIG. 2 is a II-II cross sectional view of FIG. 1 ;
  • FIG. 3 illustrates how the rail car structure is deformed due to vertical load
  • FIG. 4 is a view equivalent to FIG. 2 of another embodiment of the present invention.
  • FIG. 5 is a view equivalent to FIG. 2 of another embodiment of the present invention.
  • FIGS. 1 to 3 A first embodiment of the present invention will be described with reference to FIGS. 1 to 3 .
  • a rail car structure 20 comprises a roof component 1 forming an upper side, two side structures 2 , 2 forming lateral sides, an underframe 3 forming a lower side, and two end components 4 , 4 forming end sides.
  • Each of the roof component 1 , the side structures 2 , 2 , the underframe 3 , and the end components 4 , 4 is formed by jointing (welding or friction stir welding) a plurality of extruded members.
  • the extruded members forming the roof component 1 , the side structures 2 , 2 , and the underframe 3 are hollow members made of aluminum alloy and the hollow members are extruded in a longitudinal direction of the railroad car structure 20 .
  • the extruded members forming the end components 4 , 4 are single materials with ribs made of aluminum alloy and the single materials are extruded in a vertical direction of the railroad car structure 20 .
  • FIG. 3 illustrates how the rail car structure 20 is deformed due to vertical load.
  • FIG. 3 is a side view of the rail car structure.
  • the rail car structure 20 is supported by running gears at the centers in a running direction (the longitudinal direction of the rail car structure) of body bolsters 17 , 17 .
  • Load in the vertical direction of the rail car structure 20 is applied on the rail car structure 20 , the load being caused by the rail car structure 20 itself as well as mounted members such as electrical equipments and passengers on the vehicle.
  • the rail car structure 20 is deformed due to the vertical load so as to have a downwardly convex shape between the body bolsters 17 , 17 .
  • the deformation occurs in a concentrated manner at entrances 6 , 6 which have large openings for the passengers getting on or off. Therefore, robust entrance frames (shortly referred to as “frames” hereinafter) 7 , 7 are mounted and fixed around the entrances 6 , 6 .
  • frames also referred to as “frames” hereinafter
  • the side structure 2 is formed by a hollow member consisting of two face plates, i.e. a vehicle outer face plate 8 and a vehicle inner face plate 9 and a plurality of ribs 16 coupling the two faceplates 8 , 9 .
  • an entrance 6 is opened in the side structure 2 .
  • a frame 7 disposed along an opening edge of the entrance 6 has been directly jointed to the vehicle outer face plate 8 and the vehicle inner face plate 9 of the hollow member for the side structure 2 by means of welding or friction stir welding.
  • the side structure 2 and the frame 7 are coupled via an L-shaped fitting.
  • the L-shaped fitting 10 is a member having an L-shape as a whole in a cross section perpendicular to the opening edge as shown in FIG. 2 .
  • the L-shaped fitting 10 consists of a first joint part 10 a which is in the form of a plate and joins the vehicle inner face plate 9 and the vehicle outer face plate 8 of the side structure 2 in an end side of the side structure 2 in the side of the entrance 6 and a second joint part 10 b which is in the form of a plate and is integrally connected to the first joint part 10 a and formed to project towards the frame 7 in the side of the vehicle outer face plate 8 . Thickness of the second joint part 10 b is larger than thickness of the vehicle outer face plate 8 .
  • the first joint part 10 a is butt welded to the vehicle outer face plate 8 and the vehicle inner face plate 9 , as shown by welded parts 11 , 12 , respectively.
  • the second joint part 10 b is butt welded to the frame 7 , as shown by a welded part 13 . Because the vehicle outer face plate 8 and the vehicle inner face plate 9 are coupled by the first joint part 10 a , a distance between the vehicle outer face plate 8 and the vehicle inner face plate 9 in the edge of the side structure 2 is not changed and the face plates are firmly attached to each other, so that deformation in out-of-plane directions with respect to the vehicle outer face plate 8 and the vehicle inner face plate 9 can be suppressed which can be caused by vertical static or dynamic load acting around the opening of the entrance 6 . Because the second joint part 10 b having a large thickness firmly couples the entrance frame 7 and the vehicle outer face plate 8 by welding, the required strength can be ensured around the entrance.
  • the first joint part 10 a of the L-shaped fitting 10 is vertically placed along a vertical opening edge of the entrance 6 .
  • the first joint part 10 a may be also horizontally placed along upper and lower opening edges of the entrance 6 , continuously.
  • an extended part 7 e of the frame 7 is differently placed in relation to the vehicle inner face plate 9 in the side of the vehicle inside and they are coupled by fillet welding, as shown by a welded part 14 .
  • Plate thickness (vertical dimension in FIG. 2 ) of the second joint part 10 b of the L-shaped fitting 10 i.e. joint depth of butt welding by the welded part 13 is larger than plate thickness (vertical dimension in FIG. 2 ) of the vehicle outer faceplate 8 of the side structure 2 .
  • Outer surfaces of the L-shaped fitting 10 and the welded parts 11 , 13 for butt welding are coplanar with an outer surface of the vehicle outer face plate 8 of the side structure 2 and an outer surface of the frame 7 .
  • the outer surfaces of the vehicle outer face plate 8 of the side structure 2 , the frame 7 , and the L-shaped fitting 10 are flush with each other, i.e. coplanar.
  • the outer surfaces of the vehicle outer face plate 8 of the side structure 2 , the frame 7 , the L-shaped fitting 10 , and the welded parts 11 , 13 for butt welding are coplanar, superior design can be provided without uneven portions on the outer surface of the side structure 2 . Moreover, generation of vehicle exterior noise due to the uneven portions on the outer surface of the side structure 2 can thus be prevented.
  • the frame 7 is formed by an extruded member (a member extruded in the vertical direction in FIG. 2 ) or formed by cutting, and corner parts of vertical parts 7 a , 7 b and a horizontal part 7 c of the frame 7 can be integrally formed by welding in FIG. 1 .
  • the welding line is oblique to the corner parts.
  • cut-out parts shaped as third corner parts are placed and coupled to the vertical parts 7 a , 7 b and the horizontal part 7 c by welding.
  • FIG. 1 also shows the horizontal part 7 d of the frame 7 in the lower end of the entrance 6 , the lower horizontal part of the frame 7 is eliminated by welding the lower end of the frame to a side beam of the underframe 3 .
  • a second embodiment of the present invention will be described with reference to FIG. 4 .
  • the L-shaped fitting 10 in the embodiment in FIG. 2 is composed of a first joint part 10 A and a second joint part 10 B which are two separate members.
  • the first joint part 10 A and the second joint part 10 B are in the form of plates and it is not necessary to form an L-shaped fitting 10 with cut-out members or extruded members as in FIG. 2 . Therefore, the material and processing cost can be reduced.
  • the first joint part 10 A and the second joint part 10 B are butt welded as shown by a welded part 15 so that they are coupled to form an L-shape in a cross section perpendicular to the opening edge as shown in the figure.
  • the plate 10 B is welded to the plate 10 A here, the plate 10 B may be welded to the face plate 8 .
  • a third embodiment of the present invention will be described with reference to FIG. 5 .
  • the second joint part 10 B in the second embodiment is integrally formed with the frame 7 .
  • the second joint part is provided as a projecting part 7 B which projects from the frame 7 towards the side structure 2 .
  • the first joint part 10 A and the second joint part 7 B are welded by a welded part 15 and coupled to form an L-shape in a cross section perpendicular to the opening edge.
  • the L-shaped fitting can be easily formed and the processes of jointing the second joint part 7 B can be reduced, in comparison to the first embodiment shown in FIG. 2 .
