EMERGENCY CRASH-SYSTEM OF THE ELECTRIC TRAIN Russian patent published in 2018 - IPC B61G9/00 

FIELD: machine building; transportation.

SUBSTANCE: proposed is an emergency crash system, which includes a coupler of the leading car, the head center, two head side and inter-car crash apparatuses, in which, in order to ensure the negative acceleration continuity in the event of an accidental impact, each of the crash apparatuses contains a reducible by forcing through block die crush element, made in the form of a pipe, at that, exceeding of the structural working stroke of the head central crash apparatus over the structural working stroke of the lateral crash apparatus is (0.4…0.8) m, initial deformation force of the head central crash apparatus is (1.8…2.2) of the side crash apparatus initial deformation force, end car crash elements deformation force is (1.1…1.3) of the side crash apparatus doubled deformation force, and the total energy capacity of the head crash apparatuses is at least twice the total energy capacity of the end car crash apparatuses.

EFFECT: damage to cars is reduced, the safety of passengers is increased.
