Title:
CONTINUOUSLY VARIABLE TRANSMISSION
Document Type and Number:
WIPO Patent Application WO/2023/090610
Kind Code:
A1
Abstract:
The present invention relates to a continuously variable transmission which prevents the disconnection of power when changing gears and minimizes the load/impact of changing gears. In particular, the present invention relates to a continuously variable transmission in which the rotation direction of an eccentric disk for operating a link actuator is made to coincide with the rotation direction of an output shaft in order to prevent noise/vibration/impact that is generated when the rotation direction of the eccentric disk is opposite to the rotation direction of the output shaft. According to an embodiment of the present invention, this transmission comprises: an input shaft (2) to which power is input from the outside; a planetary gear (4) to which a portion of the power is transmitted from the input shaft (2); a driven shaft (3) to which a portion of the power is transmitted from the input shaft (2); a first link shaft (51) that rotates by receiving power transmitted from the driven shaft (3); a link actuator that is operated by the rotation of the first link shaft (51); a gear-changing lever (6) for adjusting the gear ratio of the link actuator; and an output shaft (7) that receives power transmitted from the link actuator and the planetary gear (4). The link actuator includes: an eccentric disk (501) eccentrically rotating about the first link shaft (51); a cam (502) vertically reciprocating due to the rotation of the eccentric disk (501); a first link (504) that is connected to the cam (502) and transmits power to the output shaft (7); and a one-way clutch (506) which is provided between the first link (504) and the output shaft (7) and transmits power only in the particular direction in which the output shaft (7) rotates. The first link shaft (51) is rotated by the driven shaft (3) such that the first link shaft (51) and the output shaft (7) rotate in the same direction.
