    Abstract: Multi-speed transmission for electric vehicles (EVs) can reduce the size of the electric motor and provide an appropriate balance between efficiency and dynamic performance. Currently used multi-speed transmissions for EVs were initially designed for internal combustion engine (ICE) vehicles. Since ICEs cannot operate below certain speeds and their speed control during gear changes is not an easy task, the presence of clutches or torque convertors is inevitable for start-ups, idle running and gear changing. This, however, is not the case for EVs as electric motors are speed controllable in a wide range of operating speeds. Accordingly, transmissions without clutches or torque converters are established for EVs.

    Abstract: A transmission to transfer power from an electric motor to first and second axles of a vehicle includes an input shaft adapted to be driven by the electric motor and a first planetary gear set. A second planetary gear set has a first member driven by the first planetary gear set, a second member restricted from rotation and a third member. A differential assembly has a first side gear adapted to drive the first axle, a second side gear adapted to drive the second axle and a pair of pinion gears meshed with the first and second side gears. A first clutch is operable to drivingly interconnect the first member and the differential assembly. A second clutch is operable to drivingly interconnect the third member and the differential assembly.
