Document Type and Number:
WIPO Patent Application WO/2017/065247
Kind Code:
A1
Abstract:
Provided is a continuously variable transmission in which a chain (4) wound into a groove between a fixed pulley (31) and a movable pulley (32) comprises: a link row (41) configured from a plurality of link plates (42X, 42Y); and a link pin (43) that connects the plurality of link plates (42X, 42Y). The pulley shaft (31A) of the fixed pulley (31) comprises an enlarged diameter section (31b) that is a curved surface and in which the diameter gradually increases as proximity to a first sheave surface (31a) increases. The link plates (42X, 42Y) include first link plates (42Y) overlapping with the enlarged diameter section (31b) and second link plates (42X) not overlapping with the enlarged diameter section (31b) when the winding diameter of the chain (4) is at a minimum and the link plates (42X, 42Y) are viewed from the radial direction (R) of the pulley shaft. The inner circumferential edges (42b') of the first link plates (42Y) are positioned further to the outer circumferential side than the inner circumferential edges (42b) of the second link plates (42X).
