摘要

基于传统的牵引式行星环锥式摩擦无级变速器,首先,提出了行星环锥齿轮式功率分流的无级变速器的设计方案;然后,对其整体变速比作出了两种方法的推导,并对功率流方向和功率流的分配关系作出了准确的判断;最后,对变速系统的整体传动效率进行了详细的分析计算,并用实例进行计算,与原行星环锥无级变速器传动效率进行了比较分析,并根据功率分流的比例图得出了总输入功率数值大小的范围。结果表明,经改进后的行星环锥齿轮式功率分流无级变速器的传动效率不仅比原来行星环锥无级变速器提高很多,而且总的输入功率可达到原来的行星环锥式无级变速器几倍之多,实现了大功率传动。

Abstract

Based on the traditional traction planetary ring cone friction continuously variable transmission,the planetary ring bevel gear power split type continuously variable transmission is firstly proposed,and the derivation with two methods of its overall gear ratio is carried out. Furthermore,the power flow direction and distribution relationship are obtained accurate judgments. Finally,the overall transmission efficiency of the transmission system is analyzed and calculated in detail,comparative analysis of the transmission efficiency with the original planetary rings cone continuously variable transmission is carried out by using the example. The numerical range of total input power is obtained with the power split ratio diagram. The results show that,the improved planetary ring bevel gear power split type continuously variable transmission not only has a higher transmission efficiency than the original planetary rings cone continuously variable transmission,but also the total input power of the improved transmission can be up to the original transmission a few times,a high-power transmission is achieved.
