Three speed electric vehicle transmission

A multi-speed transmission, comprising:

• an input shaft coupled to a first electric motor and a second electric motor via a first gear train;
• a first clutch shaft selectively coupled to the input shaft via a third gear train and one of a second gear train and a fourth gear train depending on a selected gear ratio;
• a second clutch shaft selectively coupled to the first clutch shaft via the second gear train;
• and
• an output shaft coupled to the second clutch shaft via a fifth gear train in one of a short drop configuration and a long drop configuration, wherein a first clutch is positioned on the first clutch shaft, a second clutch is positioned on the input shaft, and a third clutch is positioned on the second clutch shaft;
• wherein the first clutch includes a first gear that meshes with a second gear that is coupled to the input shaft;
• wherein the second clutch includes a third gear that meshes with a fourth gear that is coupled to the first clutch shaft;
• wherein the first gear meshes with a fifth gear that is included in the third clutch;
• wherein a fifth gear is coupled to or incorporated in the first clutch;
• and
• wherein a sixth gear is coupled to or incorporated in the third clutch and meshes with the fifth gear.

An electric drive unit, comprising:

• a transmission system comprising:
• an input shaft;
• a first clutch shaft;
• a second clutch shaft;
• a first clutch configured to selectively engage the first clutch shaft;
• a second clutch configured to selectively engage the input shaft;
• a third clutch configured to selectively engage the second clutch shaft;
• and
• an output shaft coupled to the second clutch shaft, wherein the output shaft is positioned in one of a first and second position relative to the input shaft;
• and
• one or more electric motors, wherein each of the one or more electric motors is coupled to the input shaft of the transmission system;
• wherein the first clutch includes a first gear that meshes with a second gear that is coupled to the input shaft;
• wherein the second clutch includes a third gear that meshes with a fourth gear that is coupled to the first clutch shaft;
• wherein the first gear meshes with a fifth gear that is included in the third clutch;
• wherein a fifth gear is coupled to or incorporated in the first clutch;
• and
• wherein a sixth gear is coupled to or incorporated in the third clutch and meshes with the fifth gear.
