  • Patent number: 5456640
    Abstract: An automatic transmission having an input annulus and a first bevel gear integrally attached to an input shaft to thereby divide torque in the input shaft into two torque components. A sun gear is rotatably mounted about the input shaft, and a set of planetary gears are in simultaneous meshing engagement (i) about the sun gear and (ii) with interior teeth of the input annulus. The sun gear includes a second bevel gear fixedly attached to a side of said sun gear and in substantial co-axial orientation with the sun gear and the first bevel gear. At least one torque-varying gear member comprises a torque-combining bevel gear and a torque-delivering gear integrally intercoupled by a stub shaft. The torque-combining bevel gear is in simultaneous meshing engagement with the first and second bevel gears, and the torque-delivering gear is in meshing engagement with an output gear, said output gear being integrally attached to an output shaft.
