Abstract

A hydraulic vectoring axle includes a differential (35) driven by a drive shaft from a pπme mover, and two axles (40) driven by the differential A differential earner (32) of the differential is geared to an element of an epicychc gear set (160, 140), another element of which is coupled to one of the axles and a hydrostatic motor (80) The differential earner is geared to a vanable displacement hydrostatic pump (90), which is hydrauhcally coupled with the hydrostatic motor A control system controls the displacement of the vanable displacement hydrostatic pump Power from the pnme mover flows pπmaπly through the differential to the output shafts Torque can be vectored from one axle to the other by selectively setting the displacement of the pump so that it dπves the motor to transmit a torque to one axle that is greater that the torque of the other axle, and the difference is determined by the displacement setting of the pump The desired torque distribution between the two wheels is determined by computer controls based on inputs from sensors in the vehicle.
