Abstract
An infinitely variable transmission system for differentially steered vehicles comprises two planetary gearboxes, each coupled to drive, as output, a driving component, such as track or wheel, on either side of a vehicle. The planetary gearboxes are drivingly coupled to a power source, such as an engine or motor, via fixed gear ratio driver and via belt drive system of two or more variable ratio belt drive pulleys. Each of the two outputs of the transmission can independently and simultaneously be controlled to revolve in forward, neutral (stop), and reverse directions in a manner of continuously and infinitesimally variable speed and torque.

An infinitely variable transmission system for differentially steered vehicles comprising;
- a driver pulley, which is drivingly connected to a power source;
- two variable ratio driven pulleys, each of which is controllably varied to control the speed and direction of rotation of each transmission output and hence each driving component;
- a single belt extending around the two driven pulleys and the driver pulley, forming a variable ratio belt drive system;
- and
- two planetary gearboxes, where gear sets of each are drivingly connected to the power source, a respective variable ratio driven pulley, and a respective driving component as output.
An infinitely variable transmission system for differentially steered vehicles comprising;
- a variable ratio driver pulley, comprising a means for continually exerting force on its flanges towards each other, that is drivingly connected to a power source;
- a variable ratio driven pulley with its flanges disconnected from each other;
- a belt extending around the driver and driven pulleys, forming a variable ratio belt drive system;
- a means for;
- controllably and independently moving each flange of the driven pulley along a respective straight path, established by the contact line between the belt and the respective flange face, established at the cross sectional view formed by the sectioning plane that passes through the axes of rotation of driver pulley and driven pulley flanges;
- and
- allowing for rotational motion of each flange about its respective axis;
- two planetary gearboxes, where gear sets of each are drivingly connected to the power source, a respective variable ratio driven pulley flange, and a respective driving component as output.
