| 摘要 |
The invention relates to a hydraulic system for controlling a twin-clutch transmission operating with wet clutches, said system containing a pump for generating a system pressure in a supply line, and a control valve device for subjecting each clutch actuator to actuating pressure derived from the system pressure and modulated according to operating states. Said system also comprises a system valve which guides hydraulic liquid conveyed by the pump into a return pipe when the system pressure is reached. The hydraulic liquid flowing through the return pipe can be supplied to the clutches for cooling same. |
