摘　　要：对大功率摩托车用无级变速传动系统中的转速感应部分调速蹄块进行分析。无级变速器主动轮的工作半径取决于调速蹄块绕固定销旋转的位移量以及调速蹄块工作曲面的形状,调速蹄块的设计影响着整个系统的速比变化。推导出调速蹄块对主动轮轴向压力影响的数学表达式,并把这个数学表达式用一个新的概念——等效半径来表示。最后,针对调速蹄块质心、工作曲面对主动轮不同的影响,改进了等效半径的公式,改进后的计算公式比先前的计算公式更加完善。The clutch weight,which is the wheel speed sensor in the continuously variable transmission system installed on the large power motorcycle,is analyzed.The displacement that clutch weight revolves around the fixed pin and the shape of cultch weight＇s working curved surface decide the working radius of CVT＇s driving wheel.The design of clutch weight affects the velocity ratio change of the whole system.The mathematical expression that the clutch weight has influence on the axial pressure of the driving wheel is deduced,and the mathematical expression is defined by a new concept,which is named equivalent radius.And finally,the expression of equivalent radius is improved based on the effect that the centre of mass of clutch weight and working curved surface have on the driving wheel,and the improved expression is more perfect.
