ABSTRACT:
A continuously variable traction transmission uses a pair of rotatable, substantially cone shaped members, one cone being connected to a power input shaft and the other cone being connected to the load output shaft. The small diameter of one cone is oriented adjacent the large diameter end of the other cone. The cone surfaces are configured such that the cones may make contact at a point or small area, for example, as seen longitudinally, the surface of one cone may be slightly convex and the surface of the other cone may be straight. The shafts on which the cones rotate are angularly adjustable with respect to each other such that the point of contact, and therefore the ratio of diameters of the cones, may be varied from one end of the cones to the other to continuously vary the input/output ratio of speed and torque transmitted through the transmission. Control systems for the transmission permit automatic or external manual control over the starting input/output ratio and over adjustment of the input/output ratio during operation.
