Abstract
A drive arrangement for a remotely controlled unmanned ground vehicle which has both tracks and wheels. The track drive and the wheel are both connected to a drive shaft assembly which includes a spring loaded axially movable splined shaft engagable and disengagable with a motor driven gear train. A ball lock key assembly is mateable with an extraction knob located at the end of the splined shaft to quickly and effortlessly disengage the shaft to allow for free-wheeling in the event of a power failure, or like problem, and to thereafter reengage the shaft for normal operation after the problem is remedied.
