Two-speed transmission for electric vehicle

A two-speed transmission that transfers torque from a motor to a final drive unit, comprising:

• an input shaft having a first end that connects with the motor and a second end opposite said first end;
• an output shaft that connects with the final drive unit;
• a planetary gear set selectively coupling said input shaft and said output shaft;
• said planetary gear set including a sun gear connected to said input shaft;
• said planetary gear set including at least one pinion having a first gear and a second gear rotatably fixed with said first gear;
• said first gear having a first diameter and said second gear having a second diameter that is different than said first diameter;
• said first gear of said at least one pinion being meshingly engaged with said sun gear and disposed radially outwardly of said sun gear;
• said planetary gear set including a ring gear meshingly engaged with said second gear of said at least one pinion and circumscribing said second gear of said at least one pinion;
• said planetary gear set including a carrier connected to said output shaft and supporting said at least one pinion;
• a brake selectively coupled to a ground;
• and
• a dog clutch selectively coupling said ring gear and said brake, said brake providing a first gear ratio by resisting rotation of said ring gear with respect to said ground when said brake and said dog clutch are engaged, wherein said dog clutch includes a plurality of teeth that interlockingly engage a component of said dog clutch that is fixed to said ground when said dog clutch is actuated to couple said ground and said brake.
