A fully mechanical, infinitely variable transmission (IVT) based onthe use of an oscillating inertia is described. The system includesa four-bar linkage mechanism, an epicyclic gear train, and a pairof one-way clutches. The IVT can be used in place of both gearbox and clutch in self-propelled vehicles. A mathematical model is presented. Numerical simulations compare the behavior of a car fitted with a manual gearbox and the same car fitted with the IVT.

Abstract
A fully mechanical, infinitely variable transmission (IVT) based onthe use of an oscillating inertia is described. The system includesa four-bar linkage mechanism, an epicyclic gear train, and a pairof one-way clutches. The IVT can be used in place of both gearbox and clutch in self-propelled vehicles. A mathematical model is presented. Numerical simulations compare the behavior of a car fitted with a manual gearbox and the same car fitted with the IVT.
