Abstract:
1. A drive system with a drive mode and freewheel mode, comprising: a motor configured to generate rotational movement; a final transfer element configured to receive and rotate with a drive axle; and a final drive assembly in rotational communication with the motor, the final drive assembly being selectively engageable with the final transfer element to drive a drive axle when the drive axle is received by the final transfer element, the final drive assembly having an engaged condition in which power is transferred through the final drive assembly to the final transfer element and a disengaged condition in which power is not transferred through the final drive assembly to the final transfer element; wherein the final drive assembly comprises a gear set positioned adjacent to the final transfer element, the gear set being selectively engagable with the final transfer element in the engaged condition such that rotation of the gear set is transferred to the final transfer element and the gear set being selectively disengageable from the final transfer element in the disengaged condition such that rotation of the final transfer element is not transferred to the gear set; wherein at least one of the final drive assembly and the final transfer element is axially movable with respect to each other between the engaged condition and the disengaged condition.
