Abstract:
A double-cavity toroidal-type continuously variable transmission, comprising:a case; a pair of input and output disks supported in the interior portion of said case such as to be concentric with each other and be rotated independently of each other, said input and output disks each including an inner surface; a trunnion disposed at a twisted position in a direction extending at right angles to the axial direction of said input and output disks, said trunnion including an even number of pivot shafts arranged concentric with each other or parallel to each other; a plurality of yokes respectively for supporting said pivot shafts of said trunnion in a swingable manner; a displacement shaft including a support shaft portion and a pivot shaft portion arranged parallel and eccentric to each other; a plurality of power rollers, while being supported in said trunnion so as to be rotatable about said displacement shaft, rollably contactable with said inner surfaces of said input and output disks; an output gear interposed between a pair of output disks for taking out the rotational movements of said output disks; a gear housing for supporting said output gear; a support post for supporting said yoke; and, a fixing member for fixing said gear housing and said support post to said case.
