Abstract
A drivetrain for a hybrid-electric vehicle (200), including an engine (210), a first electrical machine (220), a second electrical machine (230), and at least one driveshaft (260). The first (220) and second (230) electrical machines are axial-flux electrical machines. The first electrical machine (220) is arranged to be driven by the engine (210) so as to operate as a generator and to supply electrical power for the second electrical machine (230). The second electrical machine (230) is arranged to receive electrical power so as to operate as a motor and to drive the at least one driveshaft (260). The drivetrain includes a clutch (225) selectively operable to provide inter-engagement between the rotor of the first electrical machine (220) and the rotor of the second electrical machine (230) to transmit rotary power therebetween.
