Title:
CONTINUOUSLY VARIABLE TRANSMISSION
Document Type and Number:
Japanese Patent JP2013019501
Kind Code:
A
Abstract:

To reduce torque fluctuation input to a variable speed actuator from a drive source by effectively utilizing the inertial secondary moment of the variable speed actuator in a continuously variable transmission constituted by connecting an input shaft and an output shaft via a connecting rod and a one-way clutch.

The variable speed actuator 23 having an electric motor 25, a reducer 26, and an actuator housing 24 changes the change gear ratio by relatively rotating the input shaft 12 and a change gear shaft 15. The rotation of the electric motor 25 is transmitted to the gear change shaft 15 by reducing the same by the reducer 26, so that the control accuracy the change gear ratio can be enhanced by finely relatively rotating the input shaft 12 and the change gear shaft 15, and the whole of the variable speed actuator 23 having large inertial secondary moment rotates integrally with the input shaft 12 and the gear changed shaft 15, and also the torque fluctuation of the engine can be suppressed by making the variable speed actuator 23 function as a flywheel, consequently, and thereby the torque fluctuation input into the variable speed actuator 23 can be reduced and the control accuracy of the change gear ratio can be enhanced.
