Abstract

"ATENUADOR DE COLISãO COM DISPOSIçãO DE CABO E CILINDRO PARA DESACELERAR VEìCULOS". A invenção refere-se a um atenuador de colisão aperfeiçoado que utiliza uma disposição de cabo e cilindro de retenção de choque para controlar a taxa na qual um veículo que impacta o atenuador de colisão é desacelerado para uma parada segura. O atenuador de colisão está compreendido de uma seção dianteira e uma pluralidade de seções móveis com painéis laterais corrugados angulares sobrepostos. Quando o atenuador de colisão é impactado por um veículo, a seção dianteira e as seções móveis diminuem telescopicamente em resposta, e assim, são efetivamente longitudinalmente retraídas. Para este propósito, as seções estão montadas deslizantes sobre pelo menos um trilho de guia que está preso no solo. Posicionada de preferência entre dois trilhos de guia está a disposição de cabo e cilindro que exerce uma força sobre a seção dianteira para resistir ao movimento para trás da seção dianteira quando atingida por um veículo que impacta utilizando uma força de restrição variável para controlar a taxa na qual um veículo que impacta é desacelerado para parar com segurança o veículo. Os painéis laterais podem também ser utilizados em uma configuração de trilho de proteção. Uma variedade de disposições de transição para prover uma continuação suave do atenuador de colisão para um obstáculo fixo protegido pelo atenuador de colisão.
