Abstract
An energy-absorbing device for the end of rail vehicles is provided. In order in particular to reduce the cost of adaptation and matching between vehicle manufacturers and suppliers of the energy-absorbing device and the couplings (3) and the design and/or quality risks, the energy-absorbing device exhibits a base frame (1) which carries all the proposed elements for energy absorption in the end area and which is fastened as a compact preassembled module to the sub-frame (9) entirely in the defined interface area.
Claims20
An energy-absorbing device for the end of a rail vehicle with a subframe with a vertically arranged front wall interface area, the device comprising:
- a base frame;
- an energy absorbing arrangement connected only to said base frame;
- and
- a vehicle coupling fastened to said base frame through a coupling mounting, wherein said energy absorbing arrangement cooperates with said base frame to form a pre-assembled module and is fastened as a compact pre-assembled module only to the vertically arranged front wall interface area of the sub-frame of the rail vehicle.
An energy-absorbing device for the end of rail vehicles having a sub-frame interface area, the device comprising:
- a base frame;
- a bumper and an energy absorption means for absorption of forces applied to the bumper, said energy absorption means being connected exclusively to said base frame;
- and
- a vehicle coupling fastened to said base frame through a coupling mounting, wherein said energy absorption means cooperating with said base frame and said bumper to form a pre-assembled module is fastened as a compact pre-assembled module only to the vertically arranged front wall interface area of the sub frame of the rail vehicle.
A rail vehicle comprising:
- a sub frame with an interface surface extending substantially in a vertical plane;
- a base frame mounted to said sub frame;
- an energy absorbing element mounted to said base frame;
- a bumper bar mounted to said energy absorbing element;
- and
- a coupling with a coupling linkage, said coupling linkage being mounted directly to said base frame.
