Abstract
A vehicle drive system includes a primary axle driven by torque from a transmission, an output shaft or propeller shaft driven by the primary axle or transmission, a secondary axle, a secondary axle clutch, and a secondary axle drive module. The secondary axle clutch is configured to operatively connect the secondary axle with the output shaft. The secondary axle drive module is operatively connected between the output shaft and secondary axle. The drive module includes an overspeed gear set connected in parallel with a one-way clutch to facilitate application of torque to the secondary axle even when the secondary axle is rotating faster than the primary axle.
