ABSTRACT:
The invention relates to a hydraulic system (1) for providing pressures and volumetric flows in a dual clutch transmission, in particular for providing a first volumetric flow for cooling and lubricating a first clutch (2) and for providing a second volumetric flow for cooling and lubricating a second clutch (3). The hydraulic system is distinguished by the fact that at least one switching valve (4), which in a first position guides a lubricating flow onto the first clutch (2) and a cooling flow onto the second clutch (3) and in a second position guides the lubricating flow onto the second clutch (3) and the cooling flow onto the first clutch (2), is connected upstream of the first clutch (2) and the second clutch (3). The cooling flow is preferably variable.
