Abstract

Variable transmissions and drivelines using such transmissions having a direct drive mode, a reverse mode, and a continuously variable mode of operation using a continuously variable variator in combination with a gearbox having a one or two speed forward gear, a reverse gear, and a direct drive clutch. The direct drive clutch transfers power from the input shaft directly to the gearbox by running the variator in a unitary (1) speed ratio configuration, or by bypassing the variator altogether by using a set of clutches that disconnect the variator from the input shaft. Additional gears may be provided in the gearbox.
