Problems solved by technology

The latter however are only suitable when the collision-related parties are not excessively off-line and they do little to prevent the contact surface from tilting (so that a potentially undesirable tendency to climb up or slide laterally remains)

Embodiment Construction

[0036] This embodiment concerns a deformable element for a subway car. In this embodiment, the car coupler should be able to absorb shocks corresponding to speed differences of up to 15 km / h. Furthermore, the displaceable element should be able to absorb the impact energy for which the deformable element according to the invention is designed. As shown in Figures 4 and 5 (showing an example of two such wagons WG in collision motion) these elements are placed in the crumple zone at the end of the wagon WG, on the outer frame of the wagon body.

[0037] Referring to FIG. 1 , a deformable element KE has a profile part CR ("crash profile" or "crash profile") and two end plates AC, AP at the ends, which will absorb the impact load. As can be seen from the exploded view in FIG. 2 , the anti-collision molding CR has a substantially square design. Furthermore, it has a porous cross-section in which small square holes extend along the corners, leaving a cross-shaped free space ZF in ...

Abstract

Disclosed is a crumple element for a vehicle, particularly a railway vehicle, comprising a profiled part (CR) that is located between two end plates (AC, AP), has the shape of a tubular case, is provided especially with a polygonal cross section, and is used for dissipating impact energy in case of longitudinal compression caused by plastic deformation. Said crumple element further comprises a guiding element which is disposed parallel to the longitudinal direction of the profiled part (CR) and is connected in a fixed manner to the end plate (AC) facing away from the vehicle. The end plate (AP) that faces the vehicle is provided with a hole (DL) which is shaped such that the guiding element (FH) is able to longitudinally slide therethrough in a contactless manner and can be laterally inclined counter to the longitudinal direction.

Description

technical field [0001] The subject of the invention is the improvement of a deformable element of a vehicle, in particular a rail vehicle, comprising a profiled part in the form of a tubular box, in particular with a polygonal cross-section, placed between two end plates for the Dissipates impact energy by plastic deformation during longitudinal compression, and also includes a guide element arranged parallel to the longitudinal axis of the profiled part, which guide element is firmly connected to the end plate away from the vehicle and can pass through the end plate facing the vehicle. A through opening in the plate is displaced. Background technique [0002] Such deformable elements, also called crash elements in English terminology, are used in particular in vehicle production (eg rail vehicle production, truck production, etc.) as a way to control energy dissipation in the event of a collision. They are well known components of the crumple zone of a vehicle, and rail ve...
