Abstract
A modular electrically variable transmission includes at least one of a sun-shared module and a sun and ring-shared module assembled to form a two-module electrically variable transmission having a shiftable motor speed reducer subassembly and an electrically variable transmission subassembly. The sun-shared module includes a first motor-generator, an input, and primary and secondary planetary gear sets each having respective primary and secondary ring gears, carriers and associated pinion gears. The pinion gears are in meshing engagement with a single first shared sun gear that is non-rotatably coupled to the first motor-generator. The sun and ring-shared module includes a second motor-generator, a second input, a second shared sun gear and a shared ring gear, and primary and second secondary planetary gear sets. The secondary planetary gear set includes a secondary carrier supporting outer and inner pinion gears. The second shared sun gear is non-rotatably coupled to the second motor-generator.
