Zusammenfassung: | A continuously variable friction roll toroidal drive includes two variator disks which are rotatable about a common roll axis and which have tracks which are part of the circumferential surface of a torus concentric with the variator roll axis, and a plurality of rollers in contact with the tracks, each being mounted for rotation in a housing with which a support is associated. The axis of rotation of each roller being able to turn about an axis which is inclined at a certain angle to the center plane of the torus. The direction of the action of the support of each roller lies in the center plane of the torus. Each roller is mounted for rotation on a turning body. The turning body is mounted for turning in the housing, the axis of rotation of the turning body being inclined at a certain angle to the center plane of the torus. |
