Gearbox for a front axle of an electric tractor

A method for an electrified drivetrain of a vehicle, comprising:

• operating the electrified drivetrain in a first gear stage, including transmitting torque from a first input shaft coupled to an electric motor to an output shaft via a first gear set, the output shaft coupled to a first axle and/or a second axle;
• determining that a speed of the first input shaft has met a predetermined condition relative to a threshold, and in response, shifting from the first gear stage to a second gear stage and operating the electrified drivetrain in the second gear stage, including transmitting torque from the first input shaft to the output shaft via a second gear set;
• and
• determining that a request to operate a power takeoff unit has been received, and in response, transmitting torque from the first input shaft and/or from a secondary power source to the power takeoff unit via a power takeoff shaft and a third gear set, wherein the power takeoff shaft comprises a first half shaft and a second half shaft and wherein transmitting torque from the first input shaft and/or from the secondary power source to the power takeoff unit via the power takeoff shaft and the third gear set comprises transmitting torque from the secondary power source to the power takeoff unit via the second half shaft by decoupling the first half shaft from the third gear set via a first disconnect device and coupling a second input shaft to the second half shaft via the third gear set coupled to the second half shaft by a second disconnect device, the second input shaft driven by the secondary power source, the second half shaft coupled to the power takeoff unit.

An electrified drivetrain for a vehicle, comprising:

• a first input shaft configured to be driven by a first electric motor;
• a second input shaft configured to be driven by a second electric motor;
• a power takeoff shaft configured to be driven by the second electric motor;
• an output shaft coupled to a front differential and/or a rear differential;
• a gearbox including a first gear set and a second gear set each coupling the first input shaft to the output shaft and a third gear set coupling the second input shaft to the power takeoff shaft;
• and
• a first disconnect device configured to selectively decouple the output shaft from the first input shaft via the first gear set.
