MECHANISM FOR ABSORPTION OF KINETIC ENERGY RESULTED FROM FRONTAL IMPACT OF CARRIER AGAINST CARRIER RETENTION SYSTEM FOR USE ON EDGES AND AT ROAD CENTRE, SUCH AS IMPACT DAMPER AND DEAD END

摘要

FIELD: transport.;SUBSTANCE: invention relates to mechanism for absorption of kinetic energy resulted from frontal impact of carrier against the carrier retention system for use on edges and at road centre, such as impact damper and dead end. This done by propagation of plastic deformation in lengthwise direction of one or several wrought metal sections by stiff ram. The latter displaces along wrought channel overlapping a portion of its cross-section connected with system structure element. The latter receives and transmits the carrier impact at displacement along retention system. Note here that wrought channel is directly or indirectly secured to ground surface, hence, does not displace at collision.;EFFECT: carrier impact damper.;7 cl, 11 dwg
