A propulsion system for a self-propelled vehicle comprises a motor body (15) which is associated with a mechanical transmission (6) conveying motion to the driving wheels (7) of the vehicle, and which integrates and contains in a single body electric propulsion means (30), comprising at least several components (12, 13) of a brushless rotary motor (2); a clutch coupling (4) located downstream of and mechanically connected to the electric propulsion means (30); and a gearbox (5) with discontinuous gear ratios, having an input shaft (17) connected to the clutch coupling (4) and an output shaft (18) coming out to the outside of the motor body (15) and connecting to the mechanical transmission (6). The electric propulsion means (30) comprise the components (12, 13) of at least two brushless motors (2), each equipped with a respective driving shaft (3) provided with a pinion (19) which is coupled by meshing with a predetermined ratio to a clutch coupling (4). |
