摘要

無段變速器為一種可提供連續速比變化的傳動裝置，具有換檔無頓挫的優點。經過數十年來的發展，其可靠度、速比變化範圍、與扭力傳輸上限已獲得很大的改善，並在現今的汽機車市場中獲得廣泛應用。為了進一步擴大其變速範圍並提升其扭力容量，各國廠商與研究者紛紛提出各式各樣的設計，將不同的離合器與齒輪組與無段變速器相搭配，抑或結合複合動力系統以提升車輛整體的能源效率。本文首先介紹不同無段變速器的構造以及變速原理，接著說明無段變速器在傳動系統中的特殊應用方式，最後則介紹各種結合無段變速器的複合動力系統之架構。

A Continuously variable transmission (CVT) is a transmission device that provides seamless speed ratio variation without shifting shock and power interruption during ratio shifting. Its reliability, ratio coverage, and maximum allowable torque have been greatly improved after decades of development, and are widely applied in today's on-road and off-road vehicles. To increase the ratio coverage and to enhance the torque capacity, various designs and systems have been proposed to combine the CVT with different mechanisms such as clutches and gear sets. In some system, the CVT is embedded in the hybrid system with multiple power sources in order to enhance the energy efficiency. This article first introduces the structure and principle of different types of CVT, then the special applications of CVT in the transmission system are specified, and finally, the structure of hybrid system with CVT is introduced.
