Abstract

The present invention discloses a front wheel power system that can independently control power to each wheel, as well as create direct control over average and differential front wheel torque.

Description

technical field [0001] The present disclosure relates to front wheel drives, and in particular, to control of front wheel drives on work vehicles such as motor graders. Background technique [0002] Conventional work vehicles, such as motor graders, include all-wheel drive capability in which at least one motor is used to drive the front wheels and a transmission is used to transfer power from the engine or possibly an electric motor to the rear wheels. During vehicle steering, the front wheels may follow an arcuate or circular path, and when the diameter of the front wheels is equal to that of the rear wheels, for vehicle efficiency and handling experience, the front wheels may be required to rotate at a greater speed than the rear wheels because the front wheels Can travel greater distances. Furthermore, the front wheels on the outer steer diameter (outer wheels) may be required to rotate at a greater speed than the front wheels on the inner steer diameter (inner wheels),...
