Output transfer group for mobile machine powertrain

A method of transferring torque, comprising:

• receiving a torque input;
• reducing the torque input;
• splitting the torque input after reduction between two output yokes;
• and
• selectively locking the two output yokes to rotate together.

A mobile machine, comprising:

• a frame;
• a front axle rotatably supporting a front end of the frame;
• tandem rear axles rotatably supporting a rear end of the frame;
• an engine;
• a transmission connected to the engine;
• and
• an output transfer group operatively connecting the transmission to the front and tandem rear axles, the output transfer group including:
• a housing;
• an input yoke extending from the housing to connect with the transmission;
• a first output yoke extending from the housing to connect with the front axle;
• a second output yoke extending from the housing to connect with the tandem rear axles;
• and
• a gear train disposed within the housing and connecting the input yoke to the first and second output yokes, wherein:
• the gear train creates a torque reduction between the input yoke and the first and second output yokes;
• and
• the gear train includes a lockable differential located downstream of the torque reduction and configured to split the torque about 1:2 between the front axle and the tandem rear axles when the lockable differential is unlocked.
