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.

1. An infinitely variable transmission system for differentially steered vehicles comprising: a variable ratio driver pulley having a pair of flanges, comprising a means for continually exerting force on said flanges towards each other, wherein said variable ratio driver pulley is drivingly connected to a power source;a variable ratio driven pulley having a pair of flanges, with said flanges disconnected from each other;a belt extending around the driver and driven pulleys, forming a variable ratio belt drive system;wherein each flange of the driven pulley is controllably and independently movable along a respective straight path that is parallel to the contact line between the belt and the respective flange face; and wherein each flange of the driven pulley is independently rotatable 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. 2. An infinitely variable transmission system for differentially steered vehicles as in claim 1, in which; ring gears of both planetary gearboxes are drivingly connected to the power source;a planet gear carrier element of each planetary gearbox is drivingly connected to a respective driving component as a transmission output; anda sun gear of each planetary gearbox is drivingly connected to a respective variable ratio driven pulley flange, to be driven in the opposite direction of rotation of the respective ring gear. 3. An infinitely variable transmission system for differentially steered vehicles as in claim 1, in which; planet gear carrier elements of both planetary gearboxes are drivingly connected to the power source;a ring gear of each planetary gearbox is drivingly connected to a respective driving component as a transmission output; anda sun gear of each planetary gearbox is drivingly connected to a respective variable ratio driven pulley flange, to be driven in the same direction of rotation of the respective planet gear carrier element. 4. An infinitely variable transmission system for differentially steered vehicles as in claim 1, further comprising: two telescopic extending shafts, each coupled with two universal joint couplings on either ends, with further shafts extending from those universal joints to drivingly connect each driven pulley flange to a respective sun gear;two housing elements being positioned on the back side of a respective driven pulley flange, each comprising;a thrust bearing positioned in contact with the back side of each respective driven pulley flange;an opening through the body of the housing element for each respective flange's shaft to pass through, and to provide radial bearing support for each said shaft;a back face machined to be parallel to the straight path of motion of each respective flange;a set of straight cut grooves on said back face, running parallel to the respective straight path of motion of each respective flange;two guide blocks, stationarily positioned within a body of the transmission, each comprising; a front face, machined to match and be in contact with the back face of a respective housing element;raised grooves on said front face to match and slidingly engage with the cut grooves of a respective housing element; a through opening to allow each respective flange's shaft to pass through;wherein each housing element is slidable along the face of a respective guide block, to control the operations of the transmission.
