Abstract

An infinitely-variable transmission system is disclosed. The system comprises an input shaft () and an output shaft (). The transmission is operative to transmit rotational drive between the input shaft () and the output shaft (). The transmission includes a variator () that can transmit drive at a continuously variable ratio between a minimum variator ratio and a maximum variator ratio. The transmission can operate a low-speed regime and in a high-speed regime. The transmission is operative in the low-speed regime, at a neutral low regime variator ratio, the transmission is in geared neutral, in which, the output of the transmission is stationary irrespective of the speed of the input of the transmission and at a maximum low regime variator ratio, the output of the transmission is driven from the input of the transmission at a maximum low-regime transmission ratio, In the high-speed regime, at a minimum high regime variator ratio, the output of the transmission is driven from the input of the transmission at a minimum high-regime ratio and at a maximum high regime variator ratio, the output of the transmission is driven from the input of the transmission at a maximum high-regime transmission ratio.
