Abstract

"SISTEMA DE TRANSMISSãO". Uma transmissão tendo uma pluralidade de relações de engrenagens (15, 17), meios seletores (13) para engrenar seletivamente as relações de engrenagens, meios de embreagem (2) para seletivamente transmitir acionamento a partir de uma fonte de acionamento para a transmissão e um sistema de controle para controle de limite de torque de embreagem, o referido sistema de controle sendo construído e disposto para ajustar automaticamente o valor do limite de torque de embreagem antes de os meios seletores selecionarem uma relação de engrenagem desengrenada a fim de permitir movimento rotacional relativo entre os lados de entrada e saída da embreagem, se o torque excede o valor pré-determinado, quando a relação de engrenagem desengrenada é engrenada pelos meios seletores.
