Abstract
Description
- The present invention relates to a driver's cabin of a rail vehicle.
- Crashworthiness standards for railway vehicle bodies, and more specifically for the driver's cabin, usually require the provision of a survival space for the driver. This survival space must keep its integrity during a collision even in the presence of significant peak-forces. Local plastic deformation and local buckling are acceptable if it is demonstrated that they are sufficiently limited, so as not to significantly reduce the passenger and driver survival spaces. The deformation of the structure should not cause any vehicle equipment or parts (e.g. driver's desk, windscreens, etc.) to enter the designated survival space during the collision scenarios. The structure immediately ahead of the driver's survival space should, as far as practical, not fail in a manner that itself creates a hazard (e.g. exposed fracture surfaces and protrusions should be avoided).
- To meet these requirements in a driver's cabin with a driver's desk, one option is to accommodate the driver's desk into a crash-resistant cell located behind the front energy-absorbing structure, so as to make sure that the driver's desk will not be subjected to deformations. This solution, however, is space consuming.
- The standard provides that it is acceptable for the survival space to be provided in a compartment immediately adjacent to the driving position, provided that there is immediate access to it. In this respect, it has been proposed in
US 8,141,497 , to provide a sliding-type structure comprising the driver's desk as well as various shock absorbers located in front of a survival space. When the vehicle is involved in a collision, the driver must leave the desk at once to find shelter in the survival space. The sliding-type structure moves backwards towards the survival space. The shock absorbers are collapsed to absorb the shock energy while the driver's desk is moved backwards without substantial deformation. The driver is safe only insofar as he has had time to leave the desk. - The invention aims to provide a driver's cabin for a rail vehicle, which meets high crashworthiness requirements with a compact structure.
- According to a first aspect of the invention, there is provided a driver's cabin of a rail vehicle defining a front direction and comprising
- a driver's cabin structure comprising a crash-resistant structure surrounding an inner survival space of the driver's cabin and an energy-absorbing structure located in front of the crash-resistant structure and surrounding an inner crushable space of the driver's cabin, and
- a driver's desk structure located inside the driver's cabin structure and attached to the driver's cabin structure, wherein the driver's desk structure comprises a deformable framework of profiles at least partially, and preferably totally located in the inner crushable space of the driver's cabin and at least one crash-resistant crossbeam fixed to the crash-resistant structure and located, with respect to the front direction, behind the deformable framework of profiles, preferably in the inner survival space.
- This arrangement takes advantage of the space available in the inner crushable space surrounded by the energy-absorbing structure to house a deformable part of the driver's desk structure and, thanks to the crash-resistant crossbeam, prevents the deformable part of the driver's desk from penetrating the inner survival space. In the event of a frontal collision, the deformable framework of profiles will undergo a controlled deformation and will collapse, while the crash-resistant crossbeam will remain stable, i.e. substantially without deformation. The driver does not have to leave the driving position to find shelter in a remote part of the driver's cabin or outside the driver's cabin. The driver's cabin is compact, which means that more room is available for the passenger or cargo area.
- In the present application, the terms "crash-resistant" shall be used to characterise a structure or a structural component such as a crossbeam, that does not undergo a gross plastic deformations or general buckling during a frontal impact on the driver's cabin.
- Preferably, the crash-resistant crossbeam is located at a rear end, preferably a rear upper end, of the driver's desk structure. Thus, the crash-resistant crossbeam is ideally located to prevent the deformable part of the driver's desk from penetrating the inner survival space. Preferably, the crash-resistant crossbeam is located in the inner survival space.
- According to one embodiment, the crash-resistant crossbeam is located, with respect to the front direction, in front of abutments of the crash-resistant structure, and is connected to the crash-resistant structure such that during a frontal collision the crash-resistant crossbeam bears against the abutments of the crash-resistant structure. Thanks to the crash-resistant crossbeam and associated abutments of the crash-resistant structure, the driver's desk does not fully collapse and does not encroach into the survival space. The motion of the crash-resistant crossbeam itself is limited or prevented by the abutments. The survival space of the driver, acc. to EN 15227, can be located near the driver seat and desk without injuring the driver.
- According to one embodiment, the abutments include at least two abutments each facing a respective end of the crash-resistant crossbeam.
- According to a preferred embodiment, the abutments are formed by safety brackets of the crash-resistant structure. The safety brackets can be welded, bolted or riveted to another structural element, e.g. a beam of the crash-resistant structure.
- According to a preferred embodiment, the crash-resistant crossbeam is connected to the safety brackets by longitudinal connections, each comprising an elongate shaft extending in the front direction. During a frontal impact, such longitudinal connections will be subjected to compression load, or no load at all if the crash-resistant crossbeam bears directly against the abutments.
- According to an embodiment, the safety brackets vertically support the crash-resistant crossbeam. The longitudinal connection may include a L-shaped corner bracket to vertically support the crash-resistant crossbeam.
- Preferably, the deformable framework of profiles of the driver's desk structure comprises connections and/or profiles provided with structural weaknesses. These structural weaknesses ensure a controlled collapse of the deformable framework.
- According to one embodiment, the deformable framework of profiles is attached to the energy-absorbing structure, preferably via welded, bolted and/or riveted connections, in such a way that during a frontal collision, the deformable framework of profiles is crushed as a result of a deformation of the energy-absorbing structure.
- According to a preferred embodiment the driver's desk structure comprises a crash-resistant framework of profiles at least partially located in the inner survival space, and comprising the crash-resistant crossbeam and further crash-resistant profiles. Preferably, the at least one crash-resistant crossbeam is an upper crash-resistant crossbeam located at a rear upper end of the driver's desk structure, and the crash-resistant framework of profiles includes a lower crash-resistant crossbeam located below the upper crash-resistant crossbeam, preferably at a lower rear end of the driver's desk structure, and preferably located, with respect to the front direction, in front of lower abutments of the crash-resistant structure, the lower abutments being preferably formed by lower safety brackets. The lower crash-resistant crossbeam contributes to the protection of the inner survival space. Attachment brackets can be provided for attaching and vertically supporting a lower part of the crash-resistant framework of profiles to an underframe of the crash-resistant structure. Preferably, the energy-absorbing structure is fixed to the crash-resistant structure.
- According to a preferred embodiment, non structural components of the driver's desk are housed in the driver's desk structure, preferably in a free space within the deformable framework of profiles, preferably at least partially in the inner crushable space of the driver's cabin. The space available in front of the survival area is optimally used for functional components of the driver's cabin. These non structural components may include wiring and instruments, which will be crushed in the event of a frontal collision. Non structural components of the driver's desk can also be housed at least partially in a free space within the crash-resistant framework of profiles of the driver's desk structure.
- Preferably, a panelling is fixed to the driver's desk structure in the survival space, preferably between the driver's desk structure and a driver's space of the driver's cabin. The panelling will prevent ingress of non-structural components of the driver's desk into the survival space.

The panelling covers the parts of the driver'sdesk structure 46 that are located in thesurvival space 22. - During a frontal collision, the energy-absorbing
structure 18 is bent and crushed and moves towards the crash-resistant structure 14 of the driver's cab as illustrated infigures 4 and 5 . The deformable framework ofprofiles 48, which is attached to the energy-absorbingstructure 18, is crushed. Parts of the collapsed deformable framework ofprofiles 48 and of the collapsed non structural components initially housed in the deformable framework ofprofiles 48 may enter the free space within the crash-resistant framework ofprofiles 50. The crash-resistant framework ofprofiles 50, on the other hand, remains stable. In particular, the upper and lower crash-resistant crossbeams safety brackets - The deformations of the driver's
desk structure 46 take place in a controlled manner and in a predefined area without degrading the performance of the energy-absorbingstructure 18. Thanks to the upper andlower safety brackets resistant crossbeams desk structure 46 is safely attached to the side portions of the crash-resistant structure 14 of the driver'scabin 10. The part of the driver's desk that is located in thesurvival space 22 remains stable and does not translate into the driver'sspace 22 in a manner that can injure the driver. The driver does not have to leave the driving position to find shelter in a remote part of the driver's cabin or outside the driver's cabin.
