Abstract

a suspensão compreende uma mola mecânica (10) interposta entre uma massa não suspensa (um) e uma massa suspensa (sm) do veículo, um amortecedor (12) interposto entre a massa não suspensa (um) e a massa suspensa (sm) do veículo, em paralelo com a mola mecânica (10), um atuador hidráulico linear (14) disposto em série com a mola mecânica (10), um acumulador (16), um tanque (t) contendo um fluido de operação incompressível e um circuito hidráulico (18) para conectar hidraulicamente, de acordo com modos de operação pré-determinados, o atuador (14), o acumulador (16) e o tanque (t) um com o outro. o circuito hidráulico (18) compreende uma primeira linha hidráulica (20) através da qual o acumulador (16) é conectado hidraulicamente com o tanque (t), uma segunda linha hidráulica (22) através da qual o atuador (14) é conectado hidraulicamente com o tanque (t), uma terceira linha hidráulica (24) que conecta as primeira e segunda linhas hidráulicas (20, 22) uma com a outra, uma única bomba (p) que é feita como uma bomba reversível e é disposta ao longo da terceira linha hidráulica (24), um motor elétrico reversível (m) acoplado à bomba (p) para acioná-la em qualquer direção e, uma pluralidade de válvulas (v1, v2, v3, v4, v5, vs) dispostas ao longo das primeira e segunda linhas hidráulicas (20, 22) para controlar o fluxo do fluido de operação entre o acumulador (16), o tanque (t) e o atuador (14).
