Abstract

AMORTECIMENTO DEPENDENTE DO CURSO. Um absorvedor de choque de dois estágios tem um tubo de pressão dentro do qual um conjunto de pistão é disposto de forma deslizável. Uma haste de pistão é unida ao conjunto de pistão e estende-se para fora do tubo de pressão. Uma luva é disposta, de forma deslizável, dentro do tubo de pressão e acopla a haste de pistão. Depois que uma quantidade especificada de movimento do conjunto do pistão com relação ao tubo de pressão em um movimento de extensão do absorvedor de choque, a luva acopla uma pluralidade de furos posicionados, em forma de espiral, na haste de pistão e reduz o fluxo de fluido através do conjunto de válvula para comutar progressivamente o absorvedor de choque de amortecimento suave para amortecimento firme. Em uma outra concretização, a luva acopla um sulco espiral de profundidade variável na haste de pistão para reduzir o fluxo de fluido através do conjunto de válvula para comutar progressivamente o absorvedor de choque de amortecimento suave para amortecimento firme. Em, contudo, uma outra concretização da presente invenção, a luva acopla uma fenda afilada da seção reta variável para reduzir o fluxo de fluido através do conjunto de válvula para comutar progressivamente o absorvedor de choque de amortecimento suave para amortecimento firme.
