CONTIUNOUSLY VARIABLE TRANSMISSION

摘要

PROBLEM TO BE SOLVED: To reduce size and weight as well as simultaneously securing the durability of a disk 2b at an input side by improving a torque transmission mechanism between the disk 2b at the input side forming a toroidal continuously variable transmission and a first carrier 64 forming a planetary gear transmission. SOLUTION: A plurality of projections 70 are formed at a peripheral edge located outside a traction part at an internal surface side in the radial direction in an an external side of the disk 2b at the input side. Each projection 70 is engaged with a notch 69 formed at a peripheral edge of a support plate 65a of the first carrier 64. This constitution makes it possible to relieve a stress applied on the disk 2b at the input side and thin the support plate 65a so as to solve the problem. COPYRIGHT: (C)2004,JPO&NCIPI
