REVERSE GEAR STRUCTURE OF CONTINUOUSLY VARIABLE TRANSMISSION FOR VEHICLE

摘要

PURPOSE: A reverse gear structure of a continuous variable transmission for a vehicle is provided to reduce the overall size of a transmission by arranging a shift unit for moving reverse in a driving pulley side. CONSTITUTION: A continuous variable transmission unit (T3) is formed to make continuous variable transmission by making a driving pulley and a driven pulley receiving rotation power from an input shaft are connected by a belt. A sub transmission unit (T4) varies a speed ratio of the rotation power transferred from the continuous variable transmission unit. A first external gear (G1) is variably connected to the input shaft by a reverse clutch. A second external gear (G2) is engaged with the first external gear. The second external gear is connected to the sub transmission unit.
