Abstract

In this paper, we consider a continuously variable transmission (CVT). The conventional continuously variable transmissions (CVTs) are mainly classified as belt-type CVTs or toroidal CVTs. Each CVT is basically composed of several friction parts, friction wheels and other mechanical components. Because these conventional CVTs use friction force, their energy transfer efficiency might be inferior. Especially, the conventional toroidal CVTs require precise processing in shaping and surface processing since two rollers are being pushed by strong compression power. Consequently, we propose a new structural CVT in this paper. The proposed CVT consists of a couple of quadric crank chains and one-way clutches. Two identical quadric crank chains are placed symmetrically in the mechanism. Since the proposed method is not based on friction conduction, it provides a mechanism that creates no noise, is durable, and offers high transmission efficiency.
