VARIATOR DISC AND VARIATOR FOR A TOROIDAL GEARBOX

摘要

A variator disc (50; 28,30) for a toroidal variator (26), in particular, for a motor vehicle toroidal gearbox (10), is disclosed, whereby the variator disc (50; 28, 30) has a curved running surface (80), arranged coaxial to a variator axis (54) and on which rollers (34) of the toroidal variator (26) may run. The variator disc (50; 28, 30) further comprises at least two partial discs (58, 60), embodied as a traction disc (58), on which the running surface (80) is embodied, or as support disc (60) designed to support the axial forces applied to the running surface (80) and the traction disc (58) itself is supported on the support disc (60) in the radial direction out towards the variator axis (54).
