Abstract

Atuador combinado com freio de controle reológico. O presente invento se refere a um atuador combinado (17) provido de um elemento móvel (19); um acionador (20) para deslocar o elemento móvel (19); e um freio de controle reológico (23), que é mecanicamente acoplado ao elemento móvel (19) para ajustar o elemento móvel (19); o freio de controle reológico (23) tem: duas câmaras de ajuste (25) contíguas; um fluido reológico (26) contido nas duas câmaras de ajuste (25); um pistão deslizante (28), que separa de forma estanque as duas câmaras de ajuste (25) e é mecanicamente conectado ao elemento móvel (19); pelo menos um tubo de conexão externo (29) que conecta reciprocamente as duas câmaras de ajuste (25); e um dispositivo de acionamento (30) que é acoplado ao tubo de conexão externo (29) para aplicar um campo magnético variável ao fluido reológico (26) contido no tubo de conexão externo (29) para variar a viscosidade do fluido reológico (26) entre um valor mínimo e um valor máximo.
