A generic simplified layout of the IVT is shown below, this represents a layshaft layout, a coaxial layout is also possible. Beneath the diagram a brief description of each component is given.
The variator - is how the Torotrak IVT creates its continuous variation of ratio, learn more here.
The input gearset - transmits the power from the engine via the low regime clutch to the planet gear in the epicyclic gear train.
The epicyclic gearset - is the means by which the running engine can be connected to the stationary road wheels without a slipping clutch or torque converter, learn more here.
Fixed ratio chain - takes the drive from the output discs and transmits it to the sun gear of the epicyclic gearset and the input of the high regime clutch. An idling gear can be used instead of a chain.
High regime clutch - engaged for all forward speeds above the equivalent of a second gear, learn more here.
The IVT facilitates the optimum management of the engine by use of computer control, learn more here.
