Rail vehicle with impact-absorbing posts
View Patent ↗A rail vehicle with at least two impact-absorbing posts (RS 1 , RS 2 ) which are disposed in a front end region (END) and extend vertically to the floor (BOD) of the rail vehicle. A deformable area (KZO) is provided on the front side of the floor (BOD) and each impact-absorbing post (RS 1 , RS 2 ) is connected to the roof section (DAB) of the rail vehicle via the upper-end region (OE 1 , OE 2 ) thereof, each impact-absorbing post having, in the respective upper-end region thereof, a pre-determined collapsible region (OE 1 , OE 2 ) where the buckling (SK 1 , SK 2 ) of said post should occur in the event of a collision.
1. A railroad vehicle comprising:
at least two collision posts disposed in an end region of the railroad vehicle and extending perpendicularly to a floor of the railroad vehicle,
wherein a crumple zone is located at a front end region of the floor and each of the collision posts is connected at its upper end region to a roof region of the railroad vehicle,
wherein each of the collision posts has a buckling region in its upper end region where each post is adapted to buckle upon collision by having thereat a construction weaker than remaining portions of the post, and
wherein the collision posts are configured as door posts of a door opening.
2. A railroad vehicle as defined in claim 1 , wherein the buckling region of a collision post is realized by means of at least one slot-shaped recess in the collision post.
3. A railroad vehicle as defined in claim 2 , wherein each of the collision posts has two slot-shaped recesses extending parallel to each other on that side thereof which faces a body of the railroad vehicle.
4. A railroad vehicle comprising;
at least two collision posts disposed in an end region of the railroad vehicle and extending perpendicularly to a floor of the railroad vehicle,
wherein a crumple zone is located at a front end region of the floor and each of the collision posts is connected at its upper end region to a roof region of the railroad vehicle, and
wherein each of the collision posts has a buckling region in its upper end region where each post is adapted to buckle upon collision by having thereat a construction weaker than remaining portions of the post, and
wherein the buckling region of a collision post is realized by means of at least one slot-shaped recess in the collision post.
5. A railroad vehicle as defined in claim 4 , wherein each of the collision posts has two slot-shaped recesses extending parallel to each other on that side thereof which faces a body of the railroad vehicle.
