摘要： A continuously variable transmission (CVT) having a main shaft configured to support and position various components of the CVT. Shift cam discs cooperate with ball-leg assemblies to shift the transmission ration of the CVT. Load cam discs, a torsion disc, rolling elements, and a hub cap shell are configured to generate axial force, transmit torque, and manage reaction forces. In one embodiment, a splined input shaft and a torsion disc having a splined bore cooperate to input torque into the variator of the CVT. Among other things, various ball axles, axle-ball combinations, and reaction force grounding configurations are disclosed. In one embodiment, a CVT having axial force generation means at both the input and output elements is disclosed

摘要： A variable speed transmission having a plurality of tilting balls (1) and opposing input (34) and output (101) discs is illustrated and described that provides an infinite number of speed combinations over its transmission ratio range. The use of a planetary gear set allows minimum speeds to be in reverse and the unique geometry of the transmission allows all of the power paths to be coaxial, thereby reducing overall size and complexity of the transmission in comparison to transmissions achieving similar transmission ratio ranges.

摘要： A traction-drive system that in one embodiment comprises an idler (110) rotatable about a longitudinal axis, a plurality of rotatable and generally disc-shaped planet rollers (300) each having an inner contact surface (310), a case contact surface (315) and an idler contact surface (320), the inner contact surface being of a first diameter, the case contact surface being a second diameter and the idler contact surface being of a third diameter, the planet rollers distributed about the idler and each planet roller contacting the idler at its respective idler contact surface. The traction drive system of this embodiment also comprises an inner ring (400) rotatable about the longitudinal axis adapted to contact the case contact surface of each of the planet rollers. In some embodiments, the inner contact surface of each roller only contacts the inner ring, the case contact surface of each roller only contacts the case ring and the idler contact surface of each roller only contacts the idler.
