ABSTRACT PLANETARY GEAR ASSEMBLIES A planetary gear assembly (10) having a stationery housing (18) and co-axial input and output shafts (12,14) having the same diameter and spline formations of the same cross-sectional form on their adjacent end portions (12a,14a). First and second sun gears (13,15) are splined one onto each shaft end portion, a carrier (20) is rotatable about the axis of the input and output shafts, and planet gear means (22,23) carried by the carrier mesh with the sun gears. A brake (31) is provided to hold the carrier stationery 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. The arrangement allows either sun gear (13,15) to be splined onto either the input or output shaft and the meshing planet gear means to be located accordingly so that a given planetary gear assemlbly can be assembled to give either an overdrive or underdrive planetary ratio. The planetery ratio can be omitted if desired by joining the input and output shafts (12,14) with an internally-splined sleeve (50) (see Figure 4).
