Abstract
The invention concerns a hybrid drive chain of a vehicle (1) comprising a heat engine (2) connected to a mechanical assembly (4) including a gearbox (5) coupled with a differential (6) itself coupled with the driven wheels (7G, 7D) of the vehicle (1) by their respective axle shafts (8G, 8D), and at least one electrical machine (3) including a stator (10) and a rotor (11), cooperating with the heat engine (2) via the mechanical assembly to provide heat and/or hybrid traction to the driven wheels (7G, 7D). The invention is characterized in that the electrical machine (3) is arranged between the differential (6) and one of the driven wheels (7D), by surrounding the axle shaft (8D) connecting the driven wheel (7D) to the differential (6).
