AXLE DIFFERENTIAL AND METHODS OF CONTROLLING A WHEELED MULTI AXLE VEHICLE

摘要

An axle differential (200) for a vehicle includes a differential gear cluster (206) arranged in communication with a torque biasing gear cluster (208), wherein the torque biasing gear cluster is configured for varying the proportion of drive torque between the two outputs (204). A first drive path provides input (201) to the differential gear cluster and a second drive path provides input (202) to the torque biasing gear cluster, either independently of the first drive path or by diverting torque from the first drive path. A pivot turn axle differential is also provided, wherein even and odd epicyclic gear trains can be selected to cause rotation of the axle outputs in the same or opposite directions.
