Abstract

"PASSAGEM SECUNDáRIA DEPENDENTE DE CURSO". Um absorvedor de choque tem um tubo de pressao com um conjunto de pistão disposto de forma deslizante no tubo de pressão e fixado a uma haste de pistão. O conjunto de pistão divide o tubo de pressão em uma câmara de trabalho superior e uma câmara de trabalho inferior. O conjunto de pistão inclui um conjunto de válvula de compressão e de recuo. o conjunto de pistão também inclui um alojamento fixado à haste de pistão, que define uma câmara de pressão na qual é disposto de forma deslizante um pistão para a definição de câmaras de fluido superior e inferior. A câmara de pressão está em comunicação com a câmara de trabalho superior através de uma passagem que se estende através da haste de pistão. o alojamento, o pistão e as câmaras de fluido provêem um amortecimento em dois estágios no recuo e na compressão com uma transição suave entre um amortecimento suave e firme.
