ABSTRACT:
A driveline for an engined vehicle, comprises a continuously-variable ratio transmission (1) having an input, adapted to be driven by the engine, and an output (3) and first and second epicyclic gears (4, 10) for providing a high and low regime. The planet carrier (6) of the first epicyclic gear and the sun gear (12) of the second epicyclic gear are directly driven by the said output of the continuously-variable ratio transmission, and the sun gear (5) of the first epicyclic gear and the annulus (11) of the second epicyclic gear are directly driven by the engine, the annulus (7) of the first epicyclic gear providing an output in low regime, and the planet carrier (13) of the second epicyclic gear providing an output in high regime.
