    摘要: A machine (100) has an internal combustion engine (104) operating in response to a control signal provided by an engine governor (216). The engine (104) provides a torque output to a machine system providing a machine function. An electronic controller (214) determines a current operating state of the engine (104) and a torque utilization of the machine system, and compares the current operating state of the engine (104) with the torque utilization in an engine droop function (302). A change to an engine speed (308) setting of the engine (104) is instructed in response to a change in the torque signal. Such change is to increase the engine speed (308) setting when the torque utilization is increasing, and to decrease the engine speed (308) setting when the torque utilization is decreasing.

    摘要: A hydromechanical transmission includes a hydrostatic transmission, a mechanical transmission having a planetary gearing mechanism, both being driven by an engine. The output of the hydrostatic transmission interacts with the mechanical transmission to provide infinitely adjustable power flow through the hydromechanical transmission. The planetary gearing mechanism includes three planetary gear set and five members to connected the hydromechanical transmission to an output.

    摘要: An electric powertrain, a vehicle using an electric powertrain, and a method of manufacturing a vehicle having an electric powertrain are disclosed. The electric powertrain balances the ability of the vehicle to accept a given load, while at the same time affording the vehicle with an acceptable level of maneuverability. By selectively sizing the ratio of the inertia of the electric motor to the inertia of the vehicle, the optimum balance between these two competing concerns may be reached. Moreover, by optionally ensuring the Stemler Factor is less than or equal to the inertia ratio, the proper balance between load acceptance and maneuverability is attained as well.
