Abstract

A railcar includes: an underframe including a pair of side sills located at both respective ends of the underframe in a car width direction and extending in a car longitudinal direction and a plurality of cross beams coupling the pair of side sills to each other in a car width direction; and an underfloor cover covering an underfloor portion of the underframe. The underfloor cover includes upper and lower plate-shaped members (a shielding plate and a closing plate) made of stainless steel, and the upper and lower plate-shaped members are at least partially spaced apart from each other.

First claim

The invention claimed is:

1. A railcar comprising:
an underframe including
a pair of side sills located at both respective ends of the underframe in a car width direction and extending in a car longitudinal direction and
a plurality of cross beams coupling the pair of side sills to each other in the car width direction;

at least one underfloor device hung by the cross beams; and
an underfloor cover covering an underfloor portion of the underframe and including upper and lower plate-shaped members made of stainless steel, the upper and lower plate-shaped members being located lower than the underfloor device and being at least partially spaced apart from each other in an upward/downward direction,
the upper and lower plate-shaped members are provided in a range of a bottom portion of the underfloor cover, the range not overlapping the underfloor device in a plan view.

2. The railcar according to claim 1 , wherein the underfloor cover includes a heat insulating material provided between the upper and lower plate-shaped members.

3. The railcar according to claim 1 , wherein the underfloor cover includes a spacer provided between the upper and lower plate-shaped members and configured to maintain a distance of separation between the upper and lower plate-shaped members.

4. The railcar according to claim 1 , further comprising a hanging metal fitting including
a pair of post portions made of aluminum alloy and
a beam portion made of stainless steel and coupling lower end portions of the pair of post portions to each other in the car width direction,
upper portions of the pair of post portions being coupled to the cross beam, and the beam portion being coupled to the underfloor cover.

5. The railcar according to claim 1 , further comprising a hanging metal fitting including
a pair of post portions each including an upper portion made of aluminum alloy and a lower portion made of stainless steel and
a beam portion made of stainless steel and coupling lower end portions of the pair of post portions to each other in the car width direction,
the upper portions of the pair of post portions being coupled to the cross beam, and the beam portion being coupled to the underfloor cover.

6. A railcar comprising:
an underframe including
a pair of side sills located at both respective ends of the underframe in a car width direction and extending in a car longitudinal direction and
a plurality of cross beams coupling the pair of side sills to each other in the car width direction;

at least one underfloor device hung by the cross beams;
an underfloor cover covering an underfloor portion of the underframe and including upper and lower plate-shaped members made of stainless steel, the upper and lower plate-shaped members being located lower than the underfloor device and being at least partially spaced apart from each other in an upward/downward direction; and
a hanging metal fitting including
a pair of post portions made of aluminum alloy and
a beam portion made of stainless steel and coupling lower end portions of the pair of post portions to each other in the car width direction,

upper portions of the pair of post portions being coupled to the cross beam, and the beam portion being coupled to the underfloor cover.

7. The railcar according to claim 6 , wherein the underfloor cover includes a heat insulating material provided between the upper and lower plate-shaped members.

8. The railcar according to claim 6 , wherein the underfloor cover includes a spacer provided between the upper and lower plate-shaped members and configured to maintain a distance of separation between the upper and lower plate-shaped members.

9. A railcar comprising:
an underframe including
a pair of side sills located at both respective ends of the underframe in a car width direction and extending in a car longitudinal direction and
a plurality of cross beams coupling the pair of side sills to each other in the car width direction;

at least one underfloor device hung by the cross beams; and
an underfloor cover covering an underfloor portion of the underframe and including upper and lower plate-shaped members made of stainless steel, the upper and lower plate-shaped members being located lower than the underfloor device and being at least partially spaced apart from each other in an upward/downward direction; and
a hanging metal fitting including
a pair of post portions each including an upper portion made of aluminum alloy and a lower portion made of stainless steel and
a beam portion made of stainless steel and coupling lower end portions of the pair of post portions to each other in the car width direction,

the upper portions of the pair of post portions being coupled to the cross beam, and the beam portion being coupled to the underfloor cover.

10. The railcar according to claim 9 , wherein the underfloor cover includes a heat insulating material provided between the upper and lower plate-shaped members.

11. The railcar according to claim 9 , wherein the underfloor cover includes a spacer provided between the upper and lower plate-shaped members and configured to maintain a distance of separation between the upper and lower plate-shaped members.
