POWER-SPLIT-TYPE CONTINUOUSLY VARIABLE TRANSMISSION AND OIL SUPPLY STRUCTURE

摘要

A power-split-type continuously variable transmission (304) includes: a belt-type continuously variable transmission (343); a tumbler gear mechanism (344) for reversing power inputted to an input shaft (341) and transmitting the reversed power to a primary shaft (351); a planetary gear mechanism (345) having a carrier (382), a sun gear (381) provided to be capable of rotating integrally with a secondary shaft (352), and a ring gear (383) provided to be capable of rotating integrally with an output shaft (342); a split drive gear (346); a split driven gear (347) that is provided to be capable of rotating integrally with the carrier (382) and that meshes with the split drive gear (346); a clutch (C1) for engaging and disengaging the input shaft (341) and the split drive gear (346); and a clutch (C2) for engaging and disengaging the sun gear (381) and the ring gear (383).
