Power train for electrical propulsion vehicle, has transmission intercalated between motor and generator, and planetary gear whose crown gear transmits movement toward wheels of electrical propulsion vehicle
The train (10) has two electric machines including an electric motor (11) and a generator (12) connected to a planet carrier (21) and a sun gear (22) of a simple planetary gear of a continuously variable transmission (20). The transmission is intercalated between the motor and the generator. A crown gear (23) of the planetary gear transmits movement toward wheels of an electrical propulsion vehicle. The motor is maintained at an idle speed when the vehicle is in a stop position, and driven by a coolant circulation pump (50) and a compressor (51).
