Double clutch transmission with an hydraulic system to provide pressures and flows

摘要

The system has two clutches (2, 3) proceeded by a changeover valve (4), and two fluid sources for cooling and lubricating the clutches. The changeover valve includes two states in which the fluid sources are directed to the respective clutches. A control valve includes an output which communicates with the input of the changeover valve for regulating the rate of flow from one of the fluid sources into the changeover valve.
