Multi-axle vehicle steer drive system

摘要

A multi-axle vehicle steer drive system divides driving torque with a driving differential 15 and steering torque with a steering differential 20 and combines the divided torque outputs additively on one side of the vehicle and subtractively on the other side of the vehicle. This produces steer driving torque distributed via axle differentials 50 and 51 between left and right side drive axles. By using unlimited-slip differentials for dividing the driving and steering torque and no-slip differentials for distributing the steer driving torque between drive axles, the vehicle applies torque to the wheels with the best traction and drives all wheels proportionally to their tracking ability.
