CONTINUOUSLY VARIABLE TRANSMISSION

摘要

Disclosed is a continuously variable transmission including: a pair of pressing means provided movably along a shaft center connecting line obtained by connecting a shaft center of the input shaft and a shaft center of the output shaft in a disk overlapping area where the input disk and the output disk are overlapped, so that a torque transmission contact portion is formed by clamping and pressing both the disks in a position corresponding to a target shift ratio; and a pair of support means that support the pressing means by using one end side as a fulcrum, are configured to move along the shaft center connecting line in synchronization with the pressing means, and are configured to generate a force for clamping and pressing both the disks using the pressing means by virtue of a clamping force applied to the other end side.

主权项

1. A continuously variable transmission comprising:
an input shalt connected to a motor; an output shaft arranged in parallel with the input shaft; a discoidal input disk that is provided in the input shaft and has an outer circumferential edge arranged close to the output shaft; a discoidal output disk that is provided in the output shaft and has an outer circumferential edge arranged close to the input shaft; a pair of pressing units provided movably along a shaft center connecting line obtained by connecting a shaft center of the input shaft and a shaft center of the output shaft in a disk overlapping area where the input disk and the output disk are overlapped, so that a torque transmission contact portion is formed by clamping and pressing both the disks in a position corresponding to a target shift ratio to elastically deform both the disks; and a pair of support units that extend to intersect with the shaft center connecting line, support the pressing units by using one end side as a fulcrum, are configured to move along the shaft center connecting line in synchronization with the pressing units, and are configured to generate a force for clamping and pressing both the disks using the pressing units by virtue of a clamping force applied to the other end side.
