-34- Abstract of the Disclosure Nutating Traction Drive Transmission A compact nutating traction drive transmission is disclosed having particular utility in a vehicle as a steering differential. The transmission includes an input body rotatable about a central axis, first and second cone-like members rotatably mounted on the body on an inclined axis, and a pair of traction rings reacting against the respective cone-like members. A first embodiment includes a tubular shaft and a solid main shaft which are rotatably mounted and pilotably interconnected along the inclined axis, and a coupling apparatus is utilized for transmitting torque independently from the cone-like members to their respective shafts. Similar axially compact gear trains are driven by the respective shafts which have a construction and gear train ratio sufficient for maximizing the effectiveness of the transmission. A second embodiment includes a tubular shaft, a solid shaft, and an extension shaft connected to the second cone-like member for providing a greater resistance to bending centrally thereof than the first embodiment.
