摘要： A drive system for a work machine is disclosed. The drive system has at least one driven traction device and a transmission operatively connected to the at least one driven traction device. The transmission is configured to drive the at least one driven traction device. The drive system further has a controller configured to determine a ground tractive capacity associated with the at least one driven traction device and to limit an amount of torque transmitted from the transmission to the at least one driven traction device when the amount of torque to be transmitted will exceed the ground tractive capacity.

摘要： Electrical devices such as motors and generators create heat as they operate. This can lead to lower performance and life. Therefore, it is important to provide cooling for such devices. This is particularly true in heavy duty applications such as earthmoving or other industries. Methods and apparatus are disclosed to provide cooling that involves the circulation of two fluids in defined pathways. Heat within a case or other enclosure for an electrical device is transferred to one fluid. Heat from the one fluid is subsequently transferred to the other fluid. In one example, this heat transfer may occur across fins for increased effectiveness. It is also preferred that the flow of fluid be closed loop so that contaminants are not introduced into the electrical device. By providing the heat transfer out of the electrical device as described, cooling is enhanced that can lead to longer lived and better performing devices.
