Abstract
A hybrid drive unit configured for arrangement in a torque path upstream from a transmission and downstream from an internal combustion engine is provided. The hybrid drive unit includes an electric motor, a clutch configured for selectively coupling the internal combustion engine to the electric motor for driving the transmission, and a housing supporting the electric motor. The housing includes a fluid inlet channel for directing cooling fluid from the transmission to the electric motor. The hybrid drive unit also includes a filter assembly attached to the housing. The filter assembly is arranged in a fluid flow path of the cooling fluid downstream of the inlet and upstream of the electric motor. The filter assembly is configured for removing ferrous metallic particles from the cooling fluid.
