Abstract
Patente de Invenção:<B>"CONTROLADOR DE RAZãO DE TRANSMISSãO HIDROSTáTICA CONTINUAMENTE VARIáVEL CAPAZ DE GERAR FORçAS DE MOVIMENTO AMPLIFICADAS"<D>. Para controlar a razão de transmissão hidrostática continuamente variável incluindo uma haste de entrada (14), uma haste de saída (16), uma unidade de bomba hidráulica (18) acionada pela haste de entrada (14), uma unidade de motor hidráulico assentada (20), e um prato oscilante em formato de cunha (22) de forma acionada, pivotantemente conectado à haste de saída (16) e posicionado para acomodar as mudanças de fluido hidráulico bombeado entre as unidades de bomba e de motor (18, 20). Um controlador de razão é fornecido possuindo jum par de pistões diferencialmente dimensionados, hidraulicamente atuados (58,68) acoplado por um mecanismo de ligação para pivotar o prato oscilante (22) em direções de mudança de razão de transmissão oposta. O pistão menor (58) é incorporado internamente da haste de saída (16), enquanto o pistão maior (68), de um formato anular, coaxialmente circunda a haste de saída (16). O mecanismo de ligação possui uma geometria eficaz para transladar forças axiais exercidas pelos pistões (58,68) em momentos de mudança de razão amplificados exercidos no prato oscilante (22). O controlador de razão também inclui uma válvula de controle (78) seletivamente posicionada para mudar a pressão de fluido hidráulico atuando no pistão maior (68), tal como para ajustar a razão de transmissão e também determinar a direção de mudança de razão do movimento pivotante do prato oscilante.
