A trailer mounted crash attenuation system has an impact head assembly, a bursting tubular trailer frame member, and a breakaway axle assembly. Upon impact by a vehicle, the head assembly is urged forward bursting the tubular frame of the trailer. As the impact continues, the head assembly contacts an axle accelerator rod which results in the disengagement of the axle, trailer tire, and fenders from the trailer frame member. Impact energy is dissipated by the controlled deceleration of the vehicle as it moves forward through the attenuator system.
L'invention concerne un système amortisseur d'impact monté sur remorque, présentant un ensemble tête d'impact, un élément de châssis de remorque tubulaire de rupture, et un ensemble essieu de rupture. Après un impact provoqué par un véhicule, l'ensemble tête est poussé vers l'avant, provoquant la rupture du châssis tubulaire de la remorque. Lors de la progression de l'impact, l'ensemble tête vient en contact avec une barre d'accélérateur d'essieu qui provoque le désengagement de l'essieu, du pneu de remorque et des ailes de l'élément de châssis de remorque. L'énergie de l'impact est dissipée par la décélération contrôlée du véhicule lors de sa progression à travers le système amortisseur.
