Abstract
Patente de Invenção: "SISTEMA DE EMBREAGEM EM UMACAIXA DE MUDANçAS". Uma caixa de mudanças apresenta nomínimo uma embreagem de mudança (3, 4), que pode seracionada por força de mola no sentido de fechamento e, atravésde uma pressão hidráulica, pode ser acionada no sentido deabertura, e pode ser engatada de um modo tal que o meio depressão de um dispositivo de acionamento (6, 7) previamentesolicitado por pressão escoe, até um determinado nível depressão, diretamente para um reservatório de meio de pressão (21)e, abaixo de um determinado nível de pressão, encha um depósito(17, 24) e a partir desse depósito (17, 24) escoe, através de umponto de estrangulamento (22, 25), para um reservatório de meiode pressão (21), a fim de possibilitar um engate da embreagem (3,4) com modulação de pressão.
