ABSTRACT:
This invention provides improved sensitivity and ease of movement of the speed control apparatus for tractive transmissions which employ a tilting ring in contact with concave and convex tractive surfaces. A construction is shown which eliminates the need for thrust capability in the main support bearings of shafts which carry the concave and convex members. The kinematic requirements for location of ring tilting axis is defined.
