Drive train device

Trasmissione di moto a un assale

A reduced friction between pivots and a gear intended to increase human power make this model an interesting example of a multi-faceted knowledge being applied to a single device. This "drive train for a cart", in which power is transmitted to one wheel only, apparently anticipates the idea for the "differential gear", which Leonardo highlighted in later drawings.
