A transmission system suitable for operation with a drive machine includes an input shaft for a drive power, at least one output shaft for outputting drive power, a power-split transmission section having at least one variable transmission branch and a mechanical transmission branch, a manual transmission, a transmission system controller, and at least one first and second electric machine for generator and motor operation. The electric machines are electrically connected to one another. The drive power is divided up and conducted by the mechanical and variable transmission branch. An input-coupled, magnetically electric epicyclic gear stage brings together the variable transmission branch and mechanical transmission branch, and is activated by the second electric machine such that the output shaft of the transmission system rotates counter to a direction of rotation at the input shaft to provide a forward and reverse operation of the transmission system.

A vehicle includes a main drive unit, a sub drive unit, and a control unit. The main drive unit includes a main drive rotary electric machine. The sub drive unit includes a sub drive rotary electric machine. The control unit includes a driving force distribution ratio setting unit configured to set a driving force distribution ratio between the main driving force and the sub driving force and is configured to control the outputs of the main drive unit and the sub drive unit so that the main driving force and the sub driving force have the driving force distribution ratio set by the driving force distribution ratio setting unit. The driving force distribution ratio setting unit is configured to set the driving force distribution ratio to minimize electric power loss of the vehicle based on a vehicle speed of the vehicle and a required driving force of the vehicle.

An electric axle assembly includes an electric motor having an output shaft. A two stage gear train is coupled with the output shaft. The two stage gear train includes two reduction gears which provide different gear ratios. A differential is provided. A hollow differential input shaft is splined with the differential wherein the hollow input shaft supports driven gears that rotate independently relative to the hollow differential input shaft. A sliding dog clutch is splined to the hollow differential input shaft selectively engaging the driven gears or maintaining a neutral position wherein the electric motor and gear train are disconnected from the differential.

A system for proactively controlling rimpull limit of a machine includes a hydraulic system having a lift cylinder to move an implement; a lift cylinder pressure sensor that senses a hydraulic pressure of the lift cylinder and responsively produces a lift cylinder pressure signal; and a controller in operable communication with the power train and the lift cylinder pressure sensor. The controller is configured to receive the lift cylinder pressure signal; determine the rimpull limit based at least in part upon the lift cylinder pressure signal; and adjust the torque of the power train to the rimpull limit.
