Abstract

acionador eletromecânico com regulagem hidráulica, e trem de pouso equipado com esse acionador para sua manobra. acionador eletromecânico com regulagem hidráulica, e trem de pouso equipado com esse acionador para sua manobra. a presente invenção se refere a um acionador eletromecânico, comportando um motor elétrico (11) para acionar uma árvore de saída (4) em rotação por intermédio de um redutor (20) e meios de regulagem (30) passivos, permitindo um controle da velocidade de rotação da árvore de saída, e comportando um elemento de frenagem (30), disposto entre uma saída do redutor e a árvore de saída a acionar, esse elemento de frenagem sendo ajustado para assegurar dois níves de frenagem diferentes, segundo sentido de rotação da árvore, caracterizado pelo fato de o elemento de frenagem ser do tipo hidráulico e comportar meios de transvasamento (33) de fluido entre duas câmaras (34,35) sob o efeito da rotação da árvore de saída através de um elemento de laminação seletiva (41), que, segundo o sentido de rotação do acionador, opõe duas resistências distintas ao transvasamento do fluido de uma câmara à outra.
