  • Patent number: 10106034
    Abstract: 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.
    Type: Grant

  • Patent number: 9765881
    Abstract: 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.

  • Patent number: 9541183
    Abstract: 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.

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.

  • Patent number: 7418815
    Abstract: A particulate trap has a housing with an inlet and an outlet. The particulate trap also has a plurality of filters disposed within the housing in parallel relation. The particulate trap further has at least one electrode disposed within the housing and configured to impart a charge to particulates entrained within an exhaust flow as the particulates pass near the at least one electrode.

  • Patent number: 7356987
    Abstract: An exhaust gas recirculation system for a power source, has at least one inlet port configured to receive at least a portion of a flow of exhaust produced by the power source. The exhaust gas recirculation system also has an electrode disposed upstream of the at least one inlet port and configured to charge particulate matter in the flow of exhaust. The exhaust gas recirculation system further has at least one collection surface configured to allow the at least one electrode to repel the charged particulate matter away from the at least one inlet port towards the at least one collection surface.
