POWER TRANSMISSION UNIT FOR SHAFTS AND VEHICLES FOR CARRYING PASSENGERS AND GOODS

The present invention refers to a power transmission set for tractioned axles of vehicles applied, particularly in vehicles with hybrid motorization systems whose characteristics were designed and developed to provide effective control of working conditions, being fully electric, fully combustion, hybrid or even acting as an electric generator. More particularly, the present invention refers to a power transmission set which is comprised of a primary axle (10) and a secondary axle (12), which are interconnected by a selector unit (11) responsible for selecting and controlling the type of motor propulsion applied to the tread axle (R) of said vehicle (V), and, cooperatively with coupling/uncoupling devices (30, 40), it becomes possible to obtain a configuration in which only the combustion engine (MC) is responsible for propulsion; only the electric motor (ME) provides propulsion, in which both engines (MC, ME) work together to generate torque; or, also, the uncoupling of the traction of the tread axle (R) so as to feed the electric motor (ME) that becomes an electric power generator. The present invention also refers to a vehicle for the transport of cargo and passengers comprising the present power transmission set.
