A hybrid module housing includes a bulkhead. The bulkhead has a first radial channel for providing a clutch apply pressure, a second radial channel for providing a clutch cooling flow, and a third radial channel for providing a motor cooling flow. In an example embodiment, the third radial channel is arranged to be on a bottom half of the hybrid module housing when the hybrid module housing is installed in a vehicle. In an example embodiment, the first radial channel and the second radial channel are open at a radially outer surface of the bulkhead, and the third radial channel is sealed at the radially outer surface of the bulkhead. In an example embodiment, the third radial channel includes an axial passage open at a radial wall of the bulkhead.

Hybrid module cooling flow

A torque converter for a hybrid module may include a hydraulic coupling arrangement, a front cover, an impeller shell, and an electric rotor. The hydraulic coupling arrangement may include an impeller and a turbine. The front cover may have a first rim extending in a first axial direction. The front cover may at least partially encase the hydraulic coupling arrangement. The impeller shell may be fixed to the front cover and may at least partially encase the hydraulic coupling arrangement. The impeller shell may have a second rim extending in a second axial direction, opposite the first axial direction, a circumferential ring at a distal end of the second rim, and at least one impeller blade. The electric rotor may be fixed to the impeller shell second rim and axially retained by the circumferential ring.

Hybrid module configuration

A hybrid module includes a housing, an electric motor, a hydraulic coupling, a first clutch, a second clutch, and a flow plate assembly. The housing is arranged for fixing to a planetary transmission and an engine. The electric motor is disposed in the housing. The electric motor has a stator fixed to the housing and a rotor rotatable relative to the housing. The hydraulic coupling is disposed in the housing and is at least partially radially inside of the electric motor. The first clutch is for drivingly connecting the rotor to the engine. The second clutch is arranged in parallel with the hydraulic coupling for drivingly connecting the rotor to an input shaft of the planetary transmission. The flow plate assembly is fixed to the housing. The flow plate assembly has a first flow plate with a first radial groove forming a first portion of a first radial flow channel, and a second flow plate, fixed to the first flow plate, forming a second portion of the first radial flow channel.

Hybrid module

A hybrid module includes a housing, an annular stator, first and second annular rotors, and a first bearing. The housing is arranged for fixing to a combustion engine and a multi-speed transmission of a vehicle. The annular stator is fixed to the housing. The first annular rotor is disposed on a first axial side of the stator. The second annular rotor is disposed on a second axial side of the stator, opposite the first axial side. The first bearing is installed between the first annular rotor or the second annular rotor, and the annular stator. In an example embodiment, the first annular rotor or the second annular rotor includes an annular magnet. In an example embodiment, the first annular rotor is fixed to the second annular rotor.
