Abstract

resumo ?processo, e, dispositivo de comando de uma transmissão hidrostática de um veículo automotivo" processo de comando de uma transmissão hidrostática (13) de um veículo automotivo, a transmissão hidrostática (13) compreendendo um circuito de derivação (11), munido com uma válvula (12), acoplado entre dois circuitos hidráulicos complementares (9, 10) acoplando, cada, uma bomba hidráulica (3), acionada por um grupo motopropulsor (2), e acoplada a um primeiro eixo do veículo, um motor hidráulico (4) acoplado a um segundo eixo do veículo, o processo compreendendo um primeiro modo (modo 4x4lock) no qual a transmissão (13) é ativada e um segundo modo (modo 4x2) no qual a transmissão (13) é desativada para que nenhum torque motor seja transmitido ao segundo eixo e que o veículo funcione com duas rodas motrizes. o processo compreende ainda um terceiro modo (modo 4x4auto), no qual a transmissão (13) é ativada e a abertura da válvula (12) do circuito de derivação (11) é controlada para transmitir ao segundo eixo do veículo uma parte do torque motor, variável em função de um parâmetro de funcionamento (v) do veículo.
