Toroidal continuously variable transmission

摘要

In a toroidal continuously variable transmission, a link support structure of one of upper and lower links linking ends of trunnions includes a stationary portion fixed to a transmission casing. Also provided is an engagement portion formed at the link and in contact with the stationary portion. The engagement pair restricts a fore-and-aft movement of the link relative to the casing in a direction of a common rotation axis O1 of input and output disks. A freedom for the fore-and-aft movement of the link relative to the casing is relatively less than a freedom for a vertical movement of the link relative to the casing in a direction of the trunnion axis O2 and relatively less than a freedom for a left-and-right movement of the link relative to the casing in a direction normal to both the common rotation axis O1 and the trunnion axis O2.
