Title: TRANSMISSIONS
Abstract:
A transmission (10) comprising a disc variator (16) and an epicyclic gear set (40) in which the input shaft (18) of the variator (16) is connected to a first input (42) of the epicyclic gear set (40), and in which, an output (38) of the variator (16) is connected to a second input (46) of the epicyclic gear set (40). By changing the contact point (19) of a roller (34) of the variator (16), the relative speeds of the inputs (42, 46) of the epicyclic gear set (40) can be varied to provide infinitely variable control of the speed and/or direction of an output (50) of the epicyclic gear set (40). The transmission (10) can be incorporated into a transaxle transmission (20), which has a variator (16) and two epicyclic gear sets (40, 41), the respective outputs (50, 51) of which can be used to independently control the speeds and/or directions of, for example, (60, 62) connected to the respective epicyclic gear sets' output shafts (50, 51).
