Abstract:
1. A transmission for a hybrid motor vehicle provided with an internal combustion engine and with an electric machine, the transmission comprising a primary shaft adapted to be set into rotation by the electric machine, a secondary shaft, a differential for transmitting rotary motion to wheels of a first axle of the vehicle, a first transmission mechanism interposed between the primary shaft and the secondary shaft, a second transmission mechanism interposed between the secondary shaft and the differential, an overrunning clutch associated with the secondary shaft in such a manner that the secondary shaft is arranged to be set into rotation by the internal combustion engine via the overrunning clutch, and a reducer mechanism upstream of the overrunning clutch, wherein the secondary shaft is arranged to be set into rotation by the internal combustion engine via said reducer mechanism, as well as via the overrunning clutch, wherein an input gearwheel is mounted on the secondary shaft and comprises a hub and a ring gear, the hub being drivingly connected for rotation with the secondary shaft, wherein the overrunning clutch is interposed between the hub and the ring gear of the input gearwheel, and wherein the reducer mechanism comprises the ring gear and a pinion, said pinion being arranged to be set into rotation by the internal combustion engine and wherein said pinion meshes directly or indirectly with the ring gear.
