IMPROVED MULTIPLE SPEED DOUBLE PLANETARY GEAR TRANSMISSION ABSTRACT OF THE DISCLOSURE A multiple speed gear transmission includes a pair of planetary gear arrangements connected in series, the output of the first connected to the input of the second. Each such planetary gear arrangement includes on the shafts of its planets, at least two different gear surfaces of different diameters, and in one embodiment three such gear surfaces are provided. A drive annular gear connects the input of each such arrangement to one of the gear surfaces and at least two annular gears, i.e. sun gears or ring gears, are further connected with each planet gear for pro- viding different forward drives and/or reverse drive. The planet carrier is connected to the output member of each arrangement. A direct drive clutch is provided for connecting the drive annular gear directly to the planet carrier for direct drive. In one embodiment the drive annular gear of the first arrangement is a ring gear and the drive annular gear of the second arrangement is a sun gear. In another embodiment, the drive annular gears of both arrangements are ring gears.
