Abstract

AMORTECEDOR DEPENENTE DA FREQüENCIA CONTROLADO ELETRICAMENTE um amortecedor a gás inclui uma câmara de trabalho de gás pressurizado e válvulas no pistão para controle do fuxo do gás aravés do pistão. Um sistema está em comunicação com a câmara de trabalho para ontrole da pressão de gás na câmara de trabalho, de modo a controlar as características de amortecimento do amortecedor. Uma unidade de controle eletrónica é utilizada para controle da abertura e do fechamento das válvulas no pistão para também controlar as características de amortecimento do amortecedor.
