FIELD: machine building.
SUBSTANCE: invention relates to the field of collision energy damping, in particular to the energy dampening methods, to the devices implementing the energy damping method and to the railway vehicles couplings, in which such device is used. Method of collision energy damping consists in irreversible deformation of sacrificial element. Sacrificial element is a bolt made by a cold forming method. Tapered part of bolt is arranged in ring made of solid material. When the specified level of load exceeds the diameter of the wide part of the bolt decreases, it absorbs energy of collision.
EFFECT: reduction of dimensions of absorbing device.
