Abstract

A hybrid module for a drive train of a motor vehicle includes a housing, an electric machine disposed within the housing. The electric machine having a stator and a rotor arranged radially within the stator. The hybrid module having at least one hydraulically cooled friction clutch arranged radially within the rotor. A cooling device is provided that is configured to cool a plurality of friction surfaces of the at least one friction clutch and which has an annular collecting region coupled to the rotor for conjoint rotation therewith and entraining a hydraulic medium during operation, as well as a scoop section, which is secured to the housing and projects into the collecting region and via which the hydraulic medium is fed to a retaining chamber during operation.
