ABSTRACT:
A continuously variable transmission unit includes a disc drivingly connected to a first shaft, the disc having a frusto-conical groove in its outer periphery, the walls of the groove being inclined inwardly towards one another; an annular element is mounted for rotation about the disc, so that the inner periphery of the annular element is located within the groove, opposite faces of the annular element engaging the opposed walls of the groove. A connection is provided for transmitting rotation of the annular element to an output shaft and the annular element is mounted for rotation on a carrier, the carrier being adjustable radially of the disc to alter the eccentricity of the annular element with respect to the disc and to change the drive ratio of the transmission. The transmission unit may drive suitable gear trains to extend the range of drive ratios thereof. Positive drive elements may be included between the disc and annular element.
