摘要： An output transfer group is disclosed for use with a mobile machine. The output transfer group may have a housing, and an input yoke extending from the housing and configured to receive an input torque. The output transfer group may also have a first output yoke extending from the housing and configured to provide a first output torque, a second output yoke extending from the housing and configured to provide a second output torque, and a plurality of gears disposed within the housing and connecting the input yoke to the first and second output yokes. The output transfer group may further have a disk stack operatively connected to two of the plurality of gears, and an actuator configured to selectively compress the disk stack to vary a split of the input torque between the first and second output yokes. The actuator may be maintained in contact with the disk stack during operation of the output transfer group.

摘要： A hydraulic circuit is disclosed for use with a powertrain having an engine, a transmission, and an output transfer group. The hydraulic circuit may have a first sump configured to collect fluid drained from the transmission, and a second sump configured to collect fluid drained from the output transfer group. The hydraulic circuit may also have a primary pump configured to draw fluid from the first sump and generate at least one flow of pressurized fluid directed to the transmission and to the output transfer group.

摘要： An output transfer group for use with a mobile machine includes a hollow gear with a plurality of gear teeth arranged on an outer periphery of the hollow gear and configured to receive an input torque. The output transfer group also includes a differential nested inside the hollow gear and configured to split the input torque between a first output and a second output.

摘要： An output transfer group is disclosed for use with a mobile machine. The output transfer group may have a housing, an input yoke extending from the housing and configured to receive an input torque, a first output yoke extending from the housing and configured to provide a first output torque, and a second output yoke extending from the housing and configured to provide a second output torque. The output transfer group may also have a gear train disposed within the housing and connecting the input yoke to the first and second output yokes. The gear train may create a torque reduction between the input yoke and the first and second output yokes, and includes a lockable differential located downstream of the torque reduction.
