Abstract

A planetary gear assembly (10) has co-axial input and output shafts (12, 14) having the same diameter and spine formations of the same cross-sectional form on their adjacent end portions (12a, 14a). A brake (31) is provided to hold a planet carrier (20) stationary so that the assembly operates in its planetary ratio. A clutch 27 is provided to clutch a torque transmitting member (24) which is splined onto either the input or output shaft to the carrier (20) to lock-up the assembly and provide a direct drive ratio. Either of two sun gears (13, 15) may be splined onto either the input or output shaft and the meshing planet gear means (22, 23) located accordingly so that a given planetary gear assembly can be assembled to give either an overdrive or underdrive planetary ratio. The planetary ratio can be omitted if desired by joining the input and output shafts (12, 14) with an internally-splined sleeve. <IMAGE>
