Abstract

A drive unit including a drive rack with teeth on two opposite sides, with two rack gears and primary and secondary drive gears mounted on primary and secondary shafts on either sides, a tertiary drive gear mounted on a tertiary shaft; such that the, primary drive gear and the secondary gear are meshed with the tertiary gear but not each other; each said primary drive gear and secondary drive gear includes, or is attached to the associated shaft by, a freewheel device configured to allow that drive gear, when in use, to be driven by the associated shaft in only one direction, and freewheel in the other.
