Abstract

<B><MU>AMORTECEDOR PARA UM VEìCULO<MV><D>. Um amortecedor (10) para um veículo inclui um cilindro telescópico (12) e conjuntos de pistão, com o conjunto de pistão (14) incluindo dois pistões (20a, 24) conectados por um eixo de pistões (22) que passa através de uma parede frontal (12a) no cilindro (12). O fluxo de fluido de um lado da parede frontal (12a) para o outro é restringido por orifício (12c) na parede frontal (12a) e, em uma concretização alternativa, por canaletas externas (22a) no eixo de pistões (22). O pistão e cilindro podem ser guarnecidos com mola, com uma mola de suspensão helicoidal externa (16), ou podem ser impelidos no sentido de uma posição estendida por um reservatório de gás interno pressurizado. O traçado de duplo pistão do amortecedor elimina a necessidade de um reservatório de gás separado, seja no interior do amortecedor ou no exterior do amortecedor, ao mesmo tempo que também se obtém uma eficiência de traçado pela estabilização do pistão contra cargas oscilatórias, sem a necessidade de um selo de biela separado.
