Title:
CONTINUOUSLY VARIABLE TRANSMISSION BELT
Document Type and Number:
WIPO Patent Application WO/2015/008692
Kind Code:
A1
Abstract:
The present invention addresses the problem of establishing both a reduction of the friction coefficient and an improvement of the durability of the metal rings provided in a metal belt for a continuously variable transmission. A continuously variable transmission belt (15) in which multiple metal elements (32) are supported on metal ring aggregates (31), in which multiple metal rings (33) have been stacked. In the metal ring aggregates (31), at least the inner circumferential surface (33a) of the innermost metal ring (33) is provided with a puckered surface (38) having multiple protruding sections (38a) and multiple valley sections (38b) formed between said multiple protruding sections (38a). A low friction coefficient layer (51), the friction coefficient of the surface of which is lower than the friction coefficient of the surface of the protruding sections (38a), is formed in the valley sections (38b) in the puckered surface (38). The low friction coefficient layer (51) can be a fluoridated layer (51a) or a layer (51b) obtained from a DLC film.
