ABSTRACT:
A continuously variable transmission system includes an input assembly having a first member connected to an input shaft, the first member being of cylindrical formation and having a pair of axially separated inwardly directed flange formations. The opposed faces of flange formations are conical and are inclined inwardly away from one another. A second member is mounted in fixed rotational relationship but movable axially of the first member. The second member has an inwardly directed flange formation with oppositely inclined conical faces. The first and second members thereby define a pair of inwardly directed annular grooves the walls of which diverge inwardly. First and second annular discs are mounted for rotation about axes parallel to but eccentric of the axis of rotation of the input assembly, so that each disc engages in a different one of the grooves. Each disc engages the opposed conical walls of its associated groove so that drive is transmitted from the input assembly to each of the discs. The axes of rotation of discs are movable so that the radial position of engagement of each disc with the walls of the associated groove may be varied, one disc moving into the groove while the other disc moves out of groove and vice versa, so that both discs are maintained in driving engagement with the walls while the drive ratio therebetween is varied. The first disc is drivingly connected to one element, the second disc to a second element and an output is taken from the third element of an epicyclic gear train.
