METALLIC BELT ELEMENT, METALLIC BELT, AND BELTLESS CONTINUOUSLY VARIABLE TRANSMISSION

摘要

PROBLEM TO BE SOLVED: To provide a metallic belt element for use in a beltless continuously variable transmission. SOLUTION: The metallic belt element laminated in the circumferential direction of a metallic band in the form of an endless belt is composed of a porous metallic sintered body. The porous metallic sintered body is preferably manufactured by metal injection molding method and has a relative density of 95% or more. Of pores formed in the porous metallic sintered body, closed pores should preferably occupy 95% or more. COPYRIGHT: (C)2003,JPO
