Abstract
"SISTEMA DE SUSPENSãO HIDRO-PNEUMáTICO". é descrito um sistema de suspensão hidro-pneumático de eixo frontal para o eixo acionado de um veículo utilitário agrícola, especificamente para o eixo frontal de um trator agrícola, o qual contém, no mínimo, um cilindro hidráulico arranjado entre o chassi do veículo e o corpo do eixo. A câmara de extremidade da haste e a câmara de extremidade do pistão são, cada uma, conectadas a no mínimo um acumulador. Além disso, um circuito de válvula alimentado por meio de uma bomba hidráulica é fornecido para o controle de nível, o qual controla a pressão nos acumuladores como uma função da carga sobre o corpo do eixo. Para melhorar as características operacionais elásticas do veículo utilitário é proposto que os componentes mecânicos e hidráulicos sejam projetados para uma suspensão elástica sob carga máxima do corpo do eixo. O circuito de válvula é configurado e controlado de tal modo que nos acumuladores é mantida constantemente uma pressão adequada para tornar possível uma suspensão elástica do corpo de eixo sob quaisquer cargas e condições de operação do veículo.
