摘　　要：链环式超越离合器是一种原理新颖、结构独特的超越离合器，它是针对在脉动无级变速器中使用的滚柱式超越离合器的缺陷而研制的。介绍了链环式超越离合器的基本结构、数学模型和自锁条件，分析了它的三个优良特性——对制造或磨损引起的尺寸变化的宽容性、对摩擦因素不稳定的适应性和自锁裕度的充裕性及稳定性。通过与滚柱式超越离合器的对比分析，说明了链环式超越离合器在耐用寿命方面的巨大优势。Chain ring overrunning clutch is developed for the disadvantages of roller overunning clutch that is used in variable stroke drive, its working principle is original and its construction is unique. In this paper, basic construction, mathematical model and self locking requirements of chain ring overrunning clutch were introduced. Based on these, three excellent features i.e. lenity to variable dimensions caused by manufacture or wear, adaptation to unstable friction coefficient and ampleness and stablenes to self locking abundance were analyzed. On the basis of comparison and analysis, performance superiority of chain ring overrunning clutch is presented.
