  • Drive system with low speed, high torque drive mode and freewheel mode
    Patent number: 8292776
    Abstract: A drive system with drive and freewheel modes comprises a final transfer element for receiving and rotating with a drive axle, and a final drive assembly in rotational communication with a motor. The final drive assembly is selectively engageable with the final transfer element to drive an axle received by the final transfer element. The final drive assembly has an engaged condition in which power is transferred through the final drive assembly to the drive axle and a disengaged condition in which power is not transferred through the final drive assembly. The final drive assembly comprises a gear set 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. The gear set is 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.
