A compact P2 hybrid module for connecting an internal combustion engine to a transmission of a vehicle. The P2 module includes an input shaft, an electric motor having a stator and a rotor, a torque converter having a front cover and a rear cover. The torque converter further including an impeller and a turbine coupled to one another so as to form a hydrodynamic circuit, and the turbine being further coupled to an output member of the torque converter. The front cover of the torque converter being rotationally fixed with the rotor of the electric motor. An electric connect/disconnect friction clutch assembly having first and second sets of friction plates. The first and second sets of friction plates being rotationally lockable with one another during engagement of the electric connect/disconnect friction clutch assembly. An electro-mechanical controllable clutch assembly having an input member and an output member.
A compact P2 hybrid module for connecting an internal combustion engine to a transmission of a vehicle, the architecture comprising:
The compact P2 module according to any of the preceding claims, wherein the electro-mechanical controllable clutch assembly is generally located radially inward of the electric connect/disconnect friction clutch assembly.
The compact P2 module according to any of the preceding claims, wherein the first set of friction plates of the electric connect/disconnect friction clutch assembly are rotationally fixed with the rotor
The compact P2 module according to any of the preceding claims, wherein the second set of friction plates are rotationally fixed with the input shaft.
The compact P2 module according to any of the preceding claims, wherein the electric connect/disconnect friction clutch assembly further includes an actuator, the actuator including member being axially moveable and configured to engage the first and second sets of friction plates with one another during engagement of the electric connect/disconnect friction clutch assembly.
The compact P2 module according to any of the preceding claims, wherein the input member of the electro-mechanical controllable clutch assembly is rotationally fixed with the input shaft.
The compact P2 module according to any of the preceding claims, wherein the output member of the electro-mechanical controllable clutch assembly is rotationally fixed with the rotor.
The compact P2 module according to any of the preceding claims, wherein the input member of the electro-mechanical controllable clutch assembly is a clutch rotor.
The compact P2 module according to any of the preceding claims, wherein the output member of the electro-mechanical controllable clutch assembly is coupled to a clutch armature of the electro-mechanical controllable clutch assembly.
The compact P2 module according to any of the preceding claims, wherein the output member of the electro-mechanical controllable clutch assembly defines a reaction plate of the electric connect/disconnect friction clutch assembly.
The compact P2 module according to any of the preceding claims, further comprising a torque path from the engine to the transmission, the electro-mechanical controllable clutch assembly being located upstream in the torque path relative to the electric connect/disconnect friction clutch assembly.
