Abstract

A hybrid module for a hybrid vehicle is disclosed. The hybrid module has two clutches located radially inward of an electric motor, and in their own respective fluid chamber. Fluid from one chamber can cool one of the clutches. Then the fluid can travel axially to the other chamber to cool the other clutch. The hybrid module can include a wall assembly between the two clutches, separating the fluid chambers. After the fluid cools both clutches, the fluid is directed to the wall assembly, and passes through two walls, radially outwardly, to spray onto the electric motor to cool the motor.
