摘要
超越离合器系脉动无级变速器的关键部件 ,其工作能力决定了整机效率的高低、输出扭矩的大小和耐用寿命的长短。针对目前广泛使用的高副式 (如滚柱式 )超越离合器承载能力低、工作稳定性较差的缺陷 ,介绍了新型低副差动双制动块式超越离合器的演化过程。研究了衡量差动双制动块式超越离合器工作能力的自然增值系数v与制动块个数n之间的内在联系。通过对该类型超越离合器的伴生连杆机构的分析 ,认为该机构属于具有自调自适应性的内力加压装置 ,即能够自动适应输出轴在其端面两个方向上的尺寸微量变化 。
Overrunning Speed Clutch is one of the key pats in impulse Stepless Speed Regulators, and working capability depends on the control factor of its mechanism efficiency, twist moment and life - span. Aiming at the characteristic of poor dynamic - power, additional dynamic load and speed fluctuation of the higher pair Overrunning Speed Clutch, we put forward a new lower - pair Differential and Double Brake - block Overrunning Speed Clutch, and introducing the process of its evolution. The internal contact between the natural increment coefficient and brake blocks was studied, the natural increment coefficient is an important gist, which scales and distinguishes whether Differential and Double Brake - block Overrunning Speed Clutch can realize normal work or not. According to analyze the company coupler mechanism of Differential and Double Brake - block Overrunning Speed Clutch, we consider this kind of Overrunning Speed Clutch possesses the character functions that can pressurize through internal force. It can automatically adapt to the slight size change of output shaft in the direction of X axis and Y axis. So the working ability is improved.
