Title:
TRANSMISSION GEAR RATIO INFINITE CONTINUOUSLY VARIABLE TRANSMISSION
Document Type and Number:
Japanese Patent JP3473471
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To reduce deflection of a unit output shaft to improve the durability and the efficiency of power transmission.
SOLUTION: A continuously variable transmission 2 and a unit output shaft 6 are connected through a chain 40, and a helical gear or a transmission output gear 7 is provided on one end of the unit output shaft 6. When a power circulation mode is advanced, the direction of rotation of the unit output shaft 6 is set to be counterclockwise when viewed from the transmission output gear 7 side, and the tooth traces of respective helical gears on the unit output shaft 6 when viewed from the transmission output gear 7 side are set to be right hand helix for a constant transmission output gear 3b, and to be left hand helix for the transmission output gear 7.
