Title:
CONTINUOUSLY VARIABLE TRANSMISSION
Document Type and Number:
WIPO Patent Application WO/2013/008624
Kind Code:
A1
Abstract:
In the continuously variable transmission, when an eccentric disc (19) is rotated relative to an eccentric cam (18) using a gear change shaft (15) that fits coaxially into the inside of an input shaft (12), the eccentricity (ε) of the eccentric disc (19) with respect to the input shaft (12) changes and as a result of the reciprocation stroke of the connecting rod (33) changing, the intermittent rotation angle of the output shaft changes and the gear ratio is changed. Since the center of gravity (G) of the eccentric disc (19) has been made to coincide with the center of eccentric rotation (O1), even if the eccentric disc (19) is eccentrically rotated with respect to the eccentric cam (18) in order to change the gear ratio, the distance (d) from the axis line (L) of the input shaft (12) to the center of gravity (G) of the eccentric disc (19) does not change. Therefore, even if the gear ratio is changed, the second moment of inertia of the eccentric disc (19) with respect to the axial line (L) of the input shaft (12) does not change and vibrations that accompany changes in gear ratio can be kept to a minimum.
