Abstract

MOLA A AR PARA ELEVAÇçO DE UM EIXO DE RODAS DE VEÍCULO E VEÍCULO PROPORCIONADO COM UMA TAL MOLA A AR. A presente invenção se refere a uma mola a ar (1) para um veículo de suspensão a ar possuindo uma pluralidade de eixos de rodas, compreendendo um fole de ar (3) e um êmbolo mergulhador oco (6), em que a mola a ar (1) compreende uma construção de elevação localizada no interior da mola a ar (1) e sendo expansível pelo efeito da pressão de uma fonte de ar comprimido (2). Em concordância com a presente invenção, a referida mola a ar (1) está caracterizada pelo fato de que a montagem de elevação inclui um cilindro pneumático de elevação (4) interposto entre uma porção superior (9) e uma porção inferior (6) da mola a ar (1), porções (9, 6) que estão conectadas pelo fole de ar (3) A referida mola a ar (1) possibilita uma instalação compacta e eficiente em custos para um eixo de rodas de arrasto (de trailer) sobre um veículo. A presente invenção se refere a um veículo caracterizado pelo fato de que possui uma pluralidade de eixos de rodas proporcionados com uma pluralidade de molas a ar (1) conforme definidas em qualquer uma das reivindicações 1 até 13 precedentemente.
