ABSTRACT:
A rotary transmission is of the dual clutch kind and includes three gear trains through which the clutches providing alternative drive paths between a common input shaft and a common output shaft. One clutch drives the output shaft either through a two-wheel gear train or through a three-wheel train of which the first wheel is a gear wheel driven directly from the input shaft, the second wheel is a gear wheel interengaged with the first wheel and journalled on the output shaft and the third wheel is a sleeve wheel journalled on and engageable with the output shaft so that the second wheel drives the output shaft through the sleeve wheel. The other clutch is arranged to drive the output shaft either through a two-wheel gear train of which the second gear wheel is provided by the sleeve wheel or through a six-wheel gear train of which all the gear wheels are members of the first, second and third mentioned trains. In another embodiment said one clutch drives the output shaft through a second two wheel gear train which forms part of the six wheel gear train.
