Title:
CONICAL FRICTION WHEEL-TYPE CONTINUOUSLY VARIABLE TRANSMISSION
Document Type and Number:
WIPO Patent Application WO/2011/033720
Kind Code:
A1
Abstract:
Provided is a conical friction wheel-type continuously variable transmission wherein a local surface pressure caused by the movement of a contact point of an external contact surface of a ring in association with the deformation of a friction wheel is suppressed. The internal contact surface (70) of a ring (25) has a linear portion (70a), and the external contact surface (71) is comprised of a curved portion (71a) of a single arc. The contact point (P) of the curved portion is deviated toward a large diameter portion (J) of a friction wheel (23), with which the curved portion is in contact. Even if the contact point moves due to the deformation of an input-side friction wheel (22) (P→P1), the distance between the contact point and a corner is long, and accordingly, a local surface pressure is prevented from occurring at the corner.
