Hybrid drive sub-assembly for a vehicle

A motorized module for driving and braking an intermediate shaft of a hybrid sub-assembly comprising a plurality of primary toothed wheels suitable for being driven by a main engine of the vehicle, a secondary shaft suitable for driving an assembly of one or more driving wheels of the vehicle, a plurality of secondary toothed wheels capable of being coupled to the secondary shaft, and intermediate toothed wheels rigidly connected to the intermediate shaft for rotation therewith, the primary toothed wheel(s) and the secondary toothed wheel(s) each permanently meshing with a corresponding toothed wheel of the intermediate toothed wheels, the motorized module including at least one reversible electric machine capable of driving and braking the intermediate shaft, a connection interface capable of being kinematically linked to the intermediate shaft for rotation therewith, wherein the motorized module comprises a dual clutch mechanism including:

• a torque transmission casing kinematically linked to the connection interface;
• a first multi-disc clutch capable of switching from a coupled state for coupling the torque transmission casing to a first coupling member, to an uncoupled state for uncoupling the torque transmission casing from the first coupling member, the first coupling member being kinematically linked to a power take-off member;
• a second multi-disc clutch capable of switching from a coupled state for coupling the torque transmission casing to a second coupling member, to an uncoupled state for uncoupling the torque transmission casing from the second coupling member, the second coupling member being kinematically linked to the reversible electric machine;
• said motorized module comprising a speed reducer arranged kinematically between the reversible electric machine and the second coupling member.
