The hybrid propulsion system comprises: an internal combustion engine (ICE), an electric machine (EM), a primary shaft (14) adapted to receive the rotary motion from the electric machine (EM), a secondary shaft (16), a differential (36) for transmitting the rotary motion to the wheels of an axle of the vehicle, a first transmission mechanism (26) interposed between the primary shaft (14) and the secondary shaft (16) for transmitting the rotary motion between the primary shaft (14) and the secondary shaft (16), a second transmission mechanism (40) interposed between the secondary shaft (16) and the differential (36) for transmitting the rotary motion between the secondary shaft (16) and the differential (36), and an overrunning clutch (54) associated to the secondary shaft (16), whereby the secondary shaft (16) receives the rotary motion from the internal combustion engine (ICE) via the overrunning clutch (54). A reducer mechanism (58, 62) is also provided upstream of the overrunning clutch (54), whereby the secondary shaft (16) is arranged to receive the rotary motion from the internal combustion engine (ICE) via the reducer mechanism (58, 62), as well as via the overrunning clutch (54). |
