Systems and method for an electric powertrain

A system, comprising:

• a multi-speed transmission arranged in a housing, the multi-speed transmission, comprising:
• an input shaft comprising an input gear driven by two electric motors;
• a first clutch comprising a first clutch gear configured to rotate a first shaft on which a first synchronizer is arranged, wherein the first clutch is arranged on the input shaft;
• a second clutch comprising a second clutch gear configured to rotate a second shaft on which a second synchronizer is arranged, wherein the second clutch is arranged on the input shaft;
• an idler shaft comprising a plurality of gears, each in meshed engagement with a gear of either the first synchronizer or the second synchronizer;
• and
• an output shaft comprising an output gear in meshed engagement with a gear of the idler shaft.

A system, comprising:

• a first electric motor comprising a first electric motor shaft on which a first electric motor output gear is arranged;
• a second electric motor comprising a second electric motor shaft on which a second electric motor output gear is arranged;
• a multi-speed transmission arranged in a housing, the multi-speed transmission, comprising:
• an input shaft comprising an input gear driven by one or more of the first electric motor output gear and the second electric motor output gear;
• a first clutch comprising a first clutch gear configured to rotate a first shaft on which a first synchronizer is arranged, wherein the first clutch is arranged on the input shaft;
• a second clutch comprising a second clutch gear configured to rotate a second shaft on which a second synchronizer is arranged, wherein the second clutch is arranged on the input shaft;
• an idler shaft comprising a plurality of gears, each in meshed engagement with a gear of either the first synchronizer or the second synchronizer, wherein input shaft is positioned vertically above the idler shaft;
• and
• an output shaft comprising an output gear in meshed engagement with a gear of the idler shaft.
