Claims
- 1. A car body of railway rolling stock comprising:
- a roof framing including roof outer plate members of a ferrous material and roof frame members of a ferrous material;
- two side framings including side outer plate members of a ferrous material and side frame members of a ferrous material;
- two end framings including end outer plate members of a ferrous material and end frame members of a ferrous material; and
- an underframe including an end underframe and a center underframe, said end underframe comprising two side sills, two cross beams connected between said two side sills, and said center underframe including extruded shaped light alloy members, light alloy joining members welded to the ends of said center underframe as viewed in a longitudinal direction of the car body, and coupling means for coupling said joining members to said cross beams of said end underframe, wherein said cross beams are disposed in respective positions close to the center underframe, and said cross beams having coupling flanges extending toward the center underframe, said coupling flanges being connected to respective ones of said joining members by said coupling means.
- 2. A car body of railway rolling stock comprising:
- a roof framing including roof outer plate members of a ferrous material and roof frame members of a ferrous material;
- two side framings including side outer plate members of a ferrous material and side frame members of a ferrous material;
- two end framings including end outer plate members of a ferrous material and end frame members of a ferrous material; and
- an underframe including an end underframe and a center underframe, said end underframe comprising two side sills, two cross beams connected between said two side sills, and said center underframe including extruded shape light alloy members, light alloy joining members welded to the ends of said center underframe as viewed in a longitudinal directions of the car body, and coupling means for coupling said joining members to said cross beams of said underframe, wherein said side sills each has an upper flange and a lower flange extending toward a respective side of the center underframe, said center underframe having, on each side thereof, an upper flange member extending toward said upper flange of a respective one of said side sills, and a lower joining member extending toward said lower flange of said respective one of said side sills, said upper flange and said upper flange member being overlapped and connected by second coupling means, and said lower flange and said lower joining member being connected by third coupling means.
- 3. A car body of railway rolling stock comprising:
- an underframe including an end underframe comprising two side sills, two cross beams connected between said two side sills, two end beams connected between respective ends of said side sills and two floor panels all of a ferrous material, at least one of said floor panels including a keystone plate disposed on a respective one of said cross beams;
- a center underframe including extruded shaped light alloy members, and arranged between said two side sills;
- a light alloy joining member welded to an end of said center underframe,
- a joining member provided on a web of said respective one of said cross beams, coupling means for coupling said joining members together, wherein said light alloy joining member has a substantially T-shaped cross-section with a stem of said T-shape cross-section being interposed between the keystone plate and said joining member provided on the web of said respective one of said cross beams.
- 4. A car body of railway rolling stock according to claim 3, wherein a spacer is interposed between said light alloy joining member and the keystone plate.
- 5. A car body of railway rolling stock according to claim 4, wherein a clearance is provided between an end of the keystone plate and said light alloy joining member, and wherein a filler material is provided in said clearance.
