Abstract

trata-se de um sistema de transmissão (1) disposto para transmitir potência gerada por um motor (2) de um veículo. o sistema de transmissão (1) compreende uma tomada de potência (3) para acionar um implemento e uma unidade hidrostática (5) para transmitir potência a partir do motor (2) para a tomada de potência (3). a unidade hidrostática (5) compreende: uma primeira unidade de potência hidráulica (6) que tem uma primeira linha de conexão (19) e uma segunda linha de conexão (20); uma segunda unidade de potência hidráulica (7) que tem uma primeira linha de conexão (21) e uma segunda linha de conexão (22); uma válvula (23) para conectar a primeira unidade de potência hidráulica (6) e a segunda unidade de potência hidráulica (7), sendo que a válvula (23) é posicionável pelo menos em uma primeira posição e em uma segunda posição. na primeira posição, a primeira linha de conexão (19) e a segunda linha de conexão (20) da primeira unidade de potência hidráulica (6) são conectadas, respectivamente, à primeira linha de conexão (21) e à segunda linha de conexão (22) da segunda unidade de potência hidráulica (7). na segunda posição, a primeira linha de conexão (19) e a segunda linha de conexão (20) da primeira unidade de potência hidráulica (6) são conectadas, respectivamente, à segunda linha de conexão (22) e à primeira linha de conexão (21) da segunda unidade de potência hidráulica (7). a válvula (23) é controlada, de acordo com um ciclo de histerese quando exigido para comutar entre a primeira posição e a segunda posição em um valor predefinido de velocidade de motor (¿).
