Abstract

"DISPOSITIVO PARA O AUMENTO DA SEGURANçA DE FUNCIONAMENTO PARA UM CIRCUITO HIDRáULICO DE UMA EMBREAGEM ACIONáVEL HIDRAULICAMENTE". A presente invenção refere-se a um dispositivo conhecido para o aumento da segurança de funcionamento para um circuito hidráulico de uma embreagem acionável hidraulicamente, com um acumulador de pressão e um cilindro de desengate, que compreende um êmbolo primário, um êmbolo secundário e um volume de compensação, partindo daí deve ser aperfeiçoado de tal modo que, com a parada do veículo e o freio de estacionamento solto é impedida uma soltura não intencionada da embreagem. De acordo com a invenção, para isso, é empregado um dispositivo de controle da pressão e de alimentação da pressão (28), que determina uma pressão de operação de referência e uma pressão de repouso que, em caso de falhas do sistema, permite apenas um deslocamento do êmbolo secundário (16) de tal modo que, a pressão de compressão do disco de embreagem ainda é suficiente para manter o veículo na parada.
