Abstract: A track-type tractor includes a frame housing defining an internal cavity extending to an outer bore, an electric motor module, and a final drive assembly. The electric motor module includes a motor housing having a flanged end portion, and a rotor shaft extending through the flanged end portion. The flanged end portion is mounted to a outer mounting surface of the frame housing surrounding the outer bore, such that the electric motor module extends through the outer bore and is retained within the frame housing internal cavity. The final drive assembly is mounted to the flanged end portion and includes a gear set in operative engagement with the rotor shaft for motorized operation of the final drive assembly.

Abstract: An electric drive retrofit kit includes a rear entry electric drive motor module that includes an electric drive planetary gear assembly and a second electric drive planetary gear assembly which can be inserted into a rear final drive cavity of a frame housing for a tracked tractor with a high track drive. The electric drive retrofit kit may further include a generator, a cooling package, an additional water pump, a steering pump, a steering motor, power inverters with control modules, and electric cables.

Abstract: A system for managing braking torque in a machine uses a first braking system, a second braking system that is independent of the first braking system and a controller that monitors activity in both braking systems. The controller selectively reduces torque in the first braking system as torque in the second braking system increases to limit undesired effects of possible over-braking.
