FIELD: transportation.
SUBSTANCE: invention is intended for absorption of kinetic energy of impact in case of transport vehicle collision with obstacle. Energy-absorbing device comprises impact bar 1 fixed on body 2 with the help of side guides 3 and pushers installed in cavities of frame wing spars 5 and connected by crosspieces 6. Permanent magnet 7 is installed on crosspieces in the form of plate with row of through holes 8, in cavities of which compressed cylindrical springs 9 are installed, at the ends of which between impact bar 1 and permanent magnet 7 ferromagnetic plate 10 is movably installed. In magnet 7 and plate 10 openings 11 and 12 are arranged for free passage of pushers 4, and on surface of plate 10 grooves 13 are arranged for installation of pusher fixing sections 14.
EFFECT: increased efficiency of transport vehicle protection.
