Abstract:
A powertrain of a vehicle having wheels, the powertrain comprisinga mechanical gear box having five different gear ratios, at least one thermal engine having an output shaft, which shaft when required can be mechanically connected to at least one of the wheels through the mechanical gear box for driving the at least one of the wheels, an energy storage, at least one engine side electric motor and at least one tire side electric motor, which are connected to the energy storage and are supplied with electric power from the energy storage for supplying or receiving mechanical power or torque when required, connection means connected to the at least one engine side electric motor, to the at least one tire side electric motor, to the output shaft of the at least one thermal engine and to the at least one wheel for mechanically connecting the at least one engine side electric motor to the output shaft of the at least one thermal engine to be driven by the at least one thermal engine and for mechanically connecting the at least one tire side electric motor to the at least one of the wheels for driving the at least one of the wheels; and at least one device which when required performs the mechanical connection between the at least one thermal engine and the at least one wheel and is arranged in such a way that the mechanical connection is performed when a speed of an input shaft of the device is close to a speed of an output shaft of the device.
