The invention relates to a hydraulic system for supplying at least one electrical machine with a fluid for the purpose of cooling and for actuating a clutch device. The invention further relates to adrive unit for a drive train of an electrically drivable motor vehicle. The hydraulic system (1) comprises: a volumetric flow source (10), in particular a pump; the electrical machine (110, 120) to becooled; a clutch actuator (3) for actuating the clutch device (2); and a switching device (21), by means of which the fluid volumetric flow provided by the volumetric flow source (10) can be fed sequentially to the electrical machine (110, 120) and to the clutch actuator (3).
本发明涉及一种液压系统,该系统为至少一台电机供应流体,用于实现冷却和离合装置的致动。另外,本发明还涉及一种驱动单元,用于电驱动机动车的传动系。液压系统(1)包括体积流量源(10),尤其是泵,以及待冷却电机(110,120)和用于致动离合装置(2)的离合器执行元件(3),另有转换装置(21),借此将来自于体积流量源(10)的流体体积流量依次输送到电机(110,120)和离合器执行元件(3)。
