摘要
具有自调自适应性的差动双制动块式超越离合器不仅克服了高副式 (如滚柱式 )超越离合器承载能力低、工作稳定性较差的缺陷 ,同时具有工作原理可靠及结构新颖的特点。通过对差动双制动块式超越离合器的“伴生连杆机构”研究 ,认为该机构属于具有自适应性的内力加压装置 ;分析了其工作原理 ,并讨论了工作过程中的夹紧、稳定运转、超越和放松 4个阶段 ;借助于欧拉公式 ,在确定该类型机构自然增值系数的基础上 。
Differential and double brake-block overrunning speed clutch overcomes the shortcomings of low load-carrying capacity and poor stability of the higher pair overrunning speed clutch (such as the roller one) and has the advantages of automatic adaptability, reliable working principle and novel structure. Through the study of the company coupler mechanism of the differential and double brake-block overrunning speed clutch, it is realized that this kind of overrunning speed clutch can pressurize through internal force. Its working principle and the four phases in one working cycle (clamping, steady working, exceeding, loosing) are analyzed.The calulating model is proposed with the Euler-equation, on the base of defining natural increment coefficient of this type of mechanism.
