Abstract

A railway vehicle includes a carbody frame which includes a roof, a bottom side opposed to and spaced apart from the roof, two opposite sides, a front end face, and a rear end face opposite to the front end face. The roof, the bottom side, the two opposite sides and the front and rear end faces delimit altogether an inner space. One or more posts are positioned at at least one of the front and rear end faces and extend, along a substantially vertical axis, for at least a portion of a vertical distance existing between the roof and the bottom side. One or more crushable devices are connected to and extend along the substantially vertical axis for at least a predominant portion of the vertical extension of an associated post of the one or more posts.

First claim

What is claimed is:

1 . A railway vehicle comprising:
a carbody frame which includes a roof, a bottom side opposed to and spaced apart from the roof, two opposite sides, a front end face, and a rear end face opposite to the front end face along a front-rear direction, wherein the roof, the bottom side, the two opposite sides and the front and rear end faces delimit altogether an inner space, wherein a mounting face forming one of said front and rear end faces comprises a through opening configured to define a passageway; a first collision post and a second collision post which are positioned at the mounting face and extend each, along a substantially vertical axis, for at least a portion of a vertical distance existing between said roof and said bottom side, the first collision post and the second collision posts being positioned at each side of said through opening respectively, while being protruding from the mounting face inwardly towards the inner space; two crushable devices, parallel and distinct from the first collision post and the second collision post, each of the two crushable devices being connected to and extending, along said substantially vertical axis, for at least a predominant portion of the vertical extension of an associated post of said first and second collision; and a diaphragm of a gangway, which is configured to provide the passageway in and out from the railway vehicle, said diaphragm being positioned, outside said inner space, at and spaced apart from the mounting face with the diaphragm having an attachment surface facing towards said inner space, wherein said first and second crushable devices respectively comprise (i) a frame which extends vertically along said substantially vertical axis, wherein the frame has a U- or C-shaped cross section to form a profile of the vertical extension and has an elongated profile space delimited by two parallel sides and a bottom side of the profile, and (ii) a plurality of plates arranged in a sequence along said substantially vertical axis in the frame, each transversally in the elongated profile space, to be spaced apart from each other, wherein the plurality of plates are connected to the profile, wherein the first crushable device is interposed between and is connected to the first collision post and the attachment surface of the diaphragm, so that the two parallel sides in the profile of the first crushable device are spaced along the front-rear direction, while extending each parallel to the attachment surface of the diaphragm, wherein the second crushable device is interposed between and is connected to the second collision post and the attachment surface of the diaphragm, so that the two parallel sides in the profile of the second crushable device are spaced along the front-rear direction, while extending each parallel to the attachment surface of the diaphragm.

2 . The railway vehicle according to claim 1 , wherein each of the crushable devices is connected to a surface of the associated post oriented outwardly with respect to said inner space.

3 . The railway vehicle according to claim 1 , wherein each of the two crushable devices is connected in a removable way to a surface of the associated post oriented outwardly with respect to said inner space, so that the two crushable devices are protruding outwardly from the mounting face.

4 . The railway vehicle according to claim 1 , wherein each of the two crushable devices is connected in a removable way to the attachment surface of the diaphragm.

5 . The railway vehicle according to claim 1 , wherein the profiles of the two crushable devices open at two vertical profile sides with opposite orientations so that the respective bottom sides of the profiles are facing each other.

6 . The railway vehicle according to claim 1 , wherein the first collision post and the second collision post comprise at least a first corner post and a second corner posts which are positioned at the corners formed by each of the two opposite sides with the mounting face.

7 . The railway vehicle according to claim 1 , wherein each profile of the crushable devices defines three crushable device outer sides, which consist of the two parallel sides and the bottom side in said profile, and wherein the profiles of the two crushable devices are directly carrying the diaphragm.

8 . A railway vehicle comprising:
a carbody frame which includes a roof, a bottom side opposed to and spaced apart from the roof, two opposite sides, a front end face, and a rear end face opposite to the front end face along a front-rear direction, wherein the roof, the bottom side, the two opposite sides and the front and rear end faces delimit altogether an inner space, wherein a mounting face forming one of said front and rear end faces comprises a through opening configured to define a passageway; collision posts positioned at the mounting face and extending each, along a substantially vertical axis, for at least a portion of a vertical distance existing between said roof and said bottom side, the collision posts being distributed to have at least one collision post at each side of said through opening respectively; two crushable devices, parallel and distinct from the collision posts, each of the two crushable devices being connected to and extending, along said substantially vertical axis, for at least a predominant portion of the vertical extension of an associated post of said collision posts; and a diaphragm of a gangway, which is configured to provide the passageway in and out from the railway vehicle, said diaphragm being positioned, outside said inner space, at and spaced apart from the mounting face with the diaphragm having an attachment surface facing towards said inner space, wherein said first and second crushable devices respectively comprise (i) a frame which extends vertically along said substantially vertical axis, wherein the frame is a vertical frame having a U- or C-shaped cross section, thus having an elongated interior space delimited by two parallel sides and a bottom side of the vertical frame, and (ii) a plurality of plates arranged in a sequence along said substantially vertical axis in the frame, each transversally in the elongated profile space, to be spaced apart from each other, wherein the plurality of plates are connected to said vertical frame, wherein in each of the first crushable device and the second crushable device, the two parallel sides in the corresponding vertical profile are spaced along the front-rear direction, while extending each parallel to the attachment surface of the diaphragm.

9 . The railway vehicle according to claim 8 , wherein each of the first crushable device and the second crushable device is connected to a surface of the associated post oriented outwardly with respect to said inner space.

10 . The railway vehicle according to claim 8 , wherein the collision posts comprise at least a first corner post and a second corner post which are positioned at the corners formed by each of the two opposite sides with the mounting face.

11 . The railway vehicle according to claim 8 , wherein the plates are welded to the frame in the first crushable device and in the second crushable device.
