Systems and method for an electric powertrain

A system, comprising:

• an idler shaft collinear with an input shaft and parallel to a first countershaft and a second countershaft;
• a first electric motor with a first output shaft extending into a transmission casing in a direction parallel to the idler shaft;
• a second electric motor with a second output shaft extending into the transmission casing in the direction parallel to the idler shaft;
• and
• a transmission output shaft extending out of the transmission casing in the direction parallel to, the idler shaft but offset vertically below the input shaft and the idler shaft, wherein the first electric motor is positioned vertically above the second electric motor.

A system, comprising:

• an input shaft comprising an input gear driven by output gears arranged on output shafts of two electric motors, a first gear on the input shaft meshed with a first clutch and a second clutch, and a second gear on the input shaft meshed with a third clutch and a fourth clutch, wherein the output shafts of the two electric motors extend through a side of a transmission casing;
• an idler shaft comprising an idler gear and an idler shaft gear, wherein the idler shaft is collinear with the input shaft;
• a first countershaft that is selectively engaged to the first clutch or to the third clutch and is directly coupled with the idler gear via a third gear, wherein the first countershaft is parallel with the idler shaft;
• a second countershaft that is selectively engaged to the second clutch or to the fourth clutch and is directly coupled with the idler gear via a fourth gear, wherein the second countershaft is parallel with the idler shaft;
• and
• an output gear on a transmission output shaft, the output gear meshed with the idler shaft gear;
• wherein the transmission output shaft is parallel to the output shafts of the two electric motors, wherein the transmission output shaft is parallel with the input shaft but offset vertically below the input shaft and further is offset vertically below the idler shaft, and extends through the side of the transmission casing to an output member arranged outside the transmission casing, and wherein a first motor of the two electric motors is positioned vertically above a second motor of the two electric motors.
