Abstract

본 발명은 차량, 특히 건설시계에 대한 구동장치에 관한 것이다. 하나의 디젤엔진(24)에 하나의 제어펌프(25), 하나의 제어모터(1), 하나의 공급펌프(26)로 구성된 유체정력학적 변속기가 연결되어 있다. 부하변속이 가능한 유성변속기(2)와 변속변환을 위하여 변속변환밸브(34,40)가 감안되어 있다. 하나의 제동변환밸브(30)에 의하여 하나의 브레이크(14)가 작동된다. 제동변환밸브(30)는 도관부(33,39)에 의하여 변속변환밸브와 연결되어 있다. 제동변환밸브(30)의 한 변환위치에서 하나의 축압기(37)는 압력된다. 또다른 변환위치에서는 하나의 연결이 축압기로부터 브레이크의 한 압력실(20)로 이루어진다. 정상주행에 있어서 축압기는 항시 압력매체로 채워진다. 브레이크 작동시에 조정가능한 잔유압이 항시 브레이크에 작용된다. 이것은 동력학적 제동을 위하여 감안되었다. 제동은 항상 보다 고단에서 행해지며 허용되지 않은 긴 지체시간치들이 저지된다.
