Title:
BELT-TYPE CONTINUOUSLY VARIABLE TRANSMISSION
Document Type and Number:
WIPO Patent Application WO/2023/084592
Kind Code:
A1
Abstract:
The present disclosure is directed to a configuration that enables degree of freedom in designing a belt-type continuously variable transmission to be increased. A belt-type continuously variable transmission 10 according to an embodiment is a belt-type continuously variable transmission in which a belt runs over a driving pulley to which driving force from an output shaft of a motive power source is transmitted, and a driven pulley. In the belt-type continuously variable transmission, a driving mechanism includes a motor that generates driving force in an axial direction of a movable pulley half in the driving pulley, so as to move the movable pulley half with respect to a fixed pulley half. The driving mechanism is rotated by rotation of the motor, and includes a screw member that extends in the axial direction and is immovable in the axial direction, and a movable holder that has a female screw portion to which the screw member is screwed and that is movable in the axial direction along with the movable pulley half. The screw member 134 is situated on the output shaft 20 side with respect to a peripheral portion 64o of the movable pulley half 64b.
