  • System for protecting a powertrain
    Patent number: 7766791
    Abstract: A powertrain for a machine is disclosed. The powertrain has a power source and a transmission that is operably connected to the power source. The powertrain also has a differential that is operably connected to the transmission. The powertrain further has a first and second shaft that are operably connected to the differential. The first and second shaft respectively actuate a plurality of traction devices. The powertrain also has a clutch associated with the differential and configured to selectively reduce a total traction available to the machine by releasing the differential as a function of a torque produced by the power source.
