摩托车无级变速器调速特性分析

Speed characteristic analysis of continuously variable transmission for motorcycles

针对雪橇摩托车V型橡胶带无级自动变速器起步打滑和调速困难的问题,通过对主动带轮的轴向受力仿真分析,发现了导致打滑现象出现的主要原因;采用双象限调速蹄块新结构,分析了双象限调速蹄块的调速特性。分析结果表明:双象限调速蹄块不仅可以有效地解决V型橡胶带无级自动变速器起步打滑的问题,提高无级变速系统的传动效率,同时也能较好地改善雪橇摩托车无级变速传动系统的调速特性。

To solve the problems of V-belt＇s slippage during starting phase and the difficulty of the ratio change of snowmobile＇s rubber V-belt clutch system, the main reason of the V-belt＇s slippage is found based on the axial force analysis of the primary clutch. Then the speed characteristic of the continuously variable transmission with dual quadrant flyweight is analyzed. The results show that the dual quadrant flyweight not only solves the problem of the V-belt＇s slippage during starting phase effectively, but also increases the transmission efficiency of the clutch system, and improves the characteristic of ratio change of the snowmobile＇s rubber V-belt clutch system.
