Abstract

A roller transmission, in particular toroidal transmission, with infinitely variable transmission ratio, includes a friction wheel (6) disposed between a driving disk (2) and driven disk (3) and rotatably mounted to a swingable carrier (7). The friction wheel has a circumferential friction surface (8) for interaction with confronting end faces (4, 5) of both disks (2, 3). The friction wheel (6) is made of two sheet metal parts (9, 10) interconnected outside the friction surface (8) and defining a partition plane which is disposed substantially transversely to the rotation axis of the friction wheel (6), wherein at least one cavity (15) is arranged between both sheet metal parts (9, 10).
