<p>A compact nutating traction drive transmission (10) having particular utility in a vehicle (232) as a steering differential. The transmission (10) includes an input body (38) rotatable about a central axis (32), first and second cone-like members (84, 86) rotatably mounted on the body (38) on an inclined axis (32), and a pair of traction rings (60, 62) reacting against the respective cone-like members (84, 86). A first embodiment includes a tubular shaft (110) and a solid main shaft (108) which are rotatably mounted and pilotably interconnected along the inclined axis (88), and a coupling apparatus (114) is utilized for transmitting torque independently from the cone-like members (84, 86) to their respective shafts (110, 108). Similar axially compact gear trains (206) are driven by the respective shafts (110, 108) which have a construction and gear train ratio sufficient for maximizing the effectiveness of the transmission (10). A second embodiment includes a tubular shaft (110), a solid shaft (108), and an extension shaft (282) connected to the second cone-like member (86') for providing a greater resistance to bending centrally thereof than the first embodiment.</p> |
