Abstract
A drive system for a vehicle that includes a transmission with three forward and three reverse gears. The transmission is optionally coupled to an electric motor as part of a fully electric or hybrid drive system. The transmission optionally includes a first and a second planetary gearset, a first and a second brake, and a clutch which may be separated into individual drive modules, optionally in separate detachable housings. A single electric motor may be provided with a single transmission, or multiple electric motors may be included to individually drive multiple separate tires, tracks, or other earth engaging elements. Single or multiple motors may be arranged upstream or downstream of the transmission, and they may be aligned parallel with or perpendicular to a drive axle.
