Abstract

A switching unit for a hybrid module for a drivetrain of a hybrid vehicle is provided. A first clutch is selectively closable to transmit torque from a drive shaft to a first output shaft. A second clutch is selectively closable to transmit torque from the drive shaft to a second output shaft. A plurality of ducts include a cooling oil supply duct, a first cooling oil duct configured to supply cooling oil to the first clutch, and a second cooling oil duct configured to supply cooling oil to the second duct. A switching unit selectively supplies cooling oil to the first and second clutches via the first and second cooling oil ducts, respectively, wherein the switching unit includes a slide having an aperture extending therethrough, and the slide is configured to move to alternatively fluidly the coiling oil supply duct with the first or second cooling oil ducts.
