Electric variable transmission for hybrid electric vehicles with four forward modes and six fixed gears

An electric variable transmission comprising:

• a first, second, and third planetary gear set, wherein the first, second, and third planetary gear sets are interconnected;
• wherein the first planetary gear set comprises a plurality of first planetary gear subcomponents including a first sun gear, a first ring gear, and a first planetary pinion rotatably mounted on a first planetary carrier, and wherein the third planetary gear set comprises a plurality of third planetary gear subcomponents including a third sun gear, a third ring gear, and a third planetary pinion rotatably mounted on a third planetary carrier;
• an input shaft directly connected to the third planetary gear set of the third planetary gear set;
• a first electric motor continuously connected to the third planetary gear set, and additionally connected to the first planetary gear set through a first selectively engageable clutch;
• a second electric motor continuously connected to the first planetary gear set, and additionally connected to the second planetary gear set through a second selectively engageable clutch;
• a transmission housing connected to the first planetary gear set through a third selectively engageable clutch and to the second planetary gear set through a fourth selectively engageable clutch;
• a fifth selectively engageable clutch connected to at least two subcomponents on the third planetary gear set;
• an output shaft connected to the second planetary gear set;
• and
• wherein the electric variable transmission provides four forward electric variable transmission modes and six fixed gears.
