Abstract
A continuously variable transmission (CVT) includes a power transmission mechanism and at least one conical disk. The power transmission mechanism has a contact surface, and the power transmission mechanism includes a plurality of engaging elements. The plurality of engaging elements are retractably disposed on the contact surface. The disk surface of the conical disk has a plurality of engaging walls capable of engaging with the engaging elements. The continuously variable transmission is able to transmit power by way of engagement, such that the coupling between the power transmission mechanism and the conical disk is more stable. Thus, the continuously variable transmission is adaptable to high torsion application.

A continuously variable transmission, comprising:
- a power transmission mechanism having a contact surface, and the power transmission mechanism comprising a plurality of engaging elements retractably disposed on the contact surface, and
- at least one conical disk having a plurality of engaging walls extending from a center of the conical disk to an outer region of the conical disk;
- each engaging wall having a side wall and a top wall, wherein the top wall faces the contact surface, and the side wall is connected to the top wall and substantially extends along a tangent of a radial direction of the conical disk;
- wherein some of the engaging elements are in contact with the side wall while some of the engaging elements are in contact with the top wall.
