Abstract

Servo hidráulico para uma mudança de engrenagem, onde, aqui é descrito, um servo-mecanismo (1) hidráulico para uma caixa-de-mudança de engrenagem provida de um eixo (2) de controle; o servo (1) tem: um quadro (4); um primeiro atuador (5) hidráulico, o qual é conduzido pelo quadro (4) e tem duas primeiras câmaras (7), as quais são alternadamente preenchidas com um fluido pressurizado para deslocar axialmente o eixo (2) de controle nas duas direções; duas primeiras válvulas (26) solenóides, as quais controlam o enchimento das duas primeiras câmaras (7); um segundo atuador (6) hidráulico, o qual é conduzido pelo quadro (4) e tem ao menos uma segunda câmara (14) que é preenchida com um fluido pressurizado para girar o eixo (2) de controle sobre seu eixo (3) central; uma segunda válvula (27) solenóide, a qual controla o enchimento da segunda câmara (14); e um corpo (25) de suporte, o qual é fixado ao quadro (4) aloja as válvulas solenóides (26, 27), e tem dentro de si uma série de circuitos (31, 40), a qual conecta as próprias válvulas solenóides (26, 27) tanto às câmaras (7, 14) dos atuadores (5, 6) como a um suprimento do fluido pressurizado.
