ABSTRACT:
Rocker link elements (32, 33), which are located in pairs for connection of plate links (40), have end facing friction surfaces (43) which are essentially part spherical, for cooperation with essentially part spherical cone surfaces of cone disks (3, 4, 7, 8, 24-27). A base or central surface line is located approximately at a radial position of engagement with the end facing surfaces (43) of the rocker elements (32, 33) with the cone surfaces of the cones when the transmission is set for a transmission ratio of 1:1. To prevent engagement of edge regions of the rocker link elements with the respective cone disks, surface lines (54, 55) located radially outwardly, or inwardly, respectively, from a central surface line (49, 53), are inclined by an angle (.delta.), with respect to the base or central surface line. The angle of inclination (.delta.) increases, in positive or negative direction, respectively, starting at said central or base surface line about the intersection with the rocking surfaces (41, 42) in the direction to the cone surface (44) of the respective cone in engagement with the respective rocker link element. The engagement surfaces between the rocker link elements and the cone surfaces will thereby be protected by material of the rocker link elements adjacent the engagement location.
