Original Abstract Submitted
A three-speed gearbox assembly for an electric drive module (EDM) of an electric vehicle includes a housing, a first and second planetary gear set, and a first, second, third and fourth clutch. The first planetary gear set is configured to selectively connect to an output of an electric motor and includes a first sun gear, a first ring gear and a first planetary carrier. The second planetary gear set is rotationally coupled to an output of the first planetary gear set and includes a second sun gear, a second ring gear and a second planetary carrier. The first clutch selectively couples the first carrier to the housing. The second clutch selectively couples the first sun gear to the housing. The third clutch selectively couples the output of the electric motor to the first sun gear. The fourth clutch selectively couples the output of the electric motor to the first carrier.
