Abstract
SISTEMA HIDRÁULICO DE REGULAGEM DE ALTURA, PARA REGULAR A ALTURA DE UM VEÍCULO EM RELAÇÃO AO SOLO. O sistema compreende: um primeiro par de atuadores hidráulicos lineares, cada um deles colocado entre o corpo do veículo e uma respectiva roda traseira de tal forma que a extensão e compressão de cada um desses atuadores provocam um aumento e uma diminuição, respectivamente, na altura do corpo do veículo, em relação ao solo, no eixo traseiro; um segundo par de atuadores hidráulicos lineares, cada um deles colocado entre o corpo do veículo e uma respectiva roda dianteira, de tal forma que a extensão e compressão de cada um desses atuadores provocam um aumento e uma diminuição, respectivamente, na altura do corpo do veículo, em relação ao solo, no eixo dianteiro; uma unidade de abastecimento pata a geração de um fluxo de fluido, sob pressão; um tanque; um circuito hidráulico que conecta o primeiro e o segundo par de atuadores hidráulicos lineares, com a unidade de abastecimento e com o tanque; e meios de controle de fluxo, dispostos de modo a controlar o fluxo do fluido,sob pressão, de/para o primeiro e o segundo par de atuadores hidráulicos lineares, de modo a assegurar que, durante a elevação ou abaixamento do corpo do veículo, a altura do corpo do veículo, em relação ao solo, no eixo dianteiro é sempre menos do que aquela do eixo traseiro.
