V-BELT CONTINUOUSLY VARIABLE TRANSMISSION, SADDLE-RIDING-TYPE VEHICLE AND MANUFACTURING METHOD OF V-BELT CONTINUOUSLY VARIABLE TRANSMISSION

摘要

PROBLEM TO BE SOLVED: To provide a V-belt continuously variable transmission capable of simplifying an assembly process, suppressing increase of manufacturing cost, preventing deterioration of machining accuracy and avoiding disadvantage in terms of a layout space.;SOLUTION: A fixed sheave half 72a of the V-belt continuously variable transmission (CVT) 30 is equipped with a primary sheave 71 mounted to a primary sheave shaft 46c and a secondary sheave 72 mounted to a secondary sheave shaft 62. The fixed sheave half 72a of the secondary sheave 72 consists of a sheave main body part 72c in an approximately doughnut plate shape on which a V-belt 72 is wound and a boss part 72d in an approximate cylinder shape extending to the right from a right side surface of the sheave main body part 72c. The sheave main body part 72c and the boss part 72d are formed as separate parts.;COPYRIGHT: (C)2007,JPO&INPIT
