Abstract

"MóDULO DE AMORTECEDOR DE MOLA PNEUMáTICA COM AJUSTE DE AMORTECIMENTO COM BASE NA CARGA INTERNA". é propiciado um conjunto de suspensão que inclui um amortecedor que possui um alojamento cheio de fluido hidráulico. Uma mola pneumática é sustentada no amortecedor e a mola pneumática inclui uma bexiga cheia de ar. Um conjunto de válvula é circundado pelo alojamento de fluido e pela bexiga. O conjunto de válvula está em comunicação de fluido com o fluido hidráulico e o ar. O ar manipula a válvula e ajusta o fluxo do fluido hidráulico através do amortecedor para ajustar o amortecimento com base na carga do veículo experimentada na mola pneumática. De preferência, o conjunto de válvula está situado dentro da cabeça de cilindro interno posicionado entre a haste do pistão e a parede cilíndrica externa do amortecedor. O conjunto de válvula pode incluir uma válvula de vaivém que coopera com outras válvulas e molas para propiciar amortecimento variável ao longo da carga do veículo experimentada pela mola interna. Alternativamente, uma válvula linear de duas posições pode ser utilizada para alterar o amortecimento em resposta a uma pressão predeterminada dentro da mola pneumática correspondente a uma carga de veículo específica.
