The Research of NewPlanetary Ring Tapered Gear Divergent Power on CVT

基于当前无级变速器油耗大,传动效率偏低,传动结构复杂的缺陷,设计一种新型行星环锥齿轮功率分流式无级变速器,即RX环锥齿轮无级变速器与2K-H无级变速器的组合。对传统无级变速器进行结构改进设计,在原传动调速的基础上,以高效率,大变速比为研究设计目标,对其理论分析和研究。结果表明:该新型变速器传动效率高,变速范围广,有效实现传动比的无级变化,无封闭功率循环现象和无根切现象出现;且其传动系统中的调速性能及传动效率均优于原行星锥齿轮变速器;具有很高的推广实用价值。

Based on current fuel consumption slightly larger CVT, Lower transmission efficiency, defects of complex transmission structure, Proposes a new power split planetary ring bevel gear-type continuously vari-able transmission. That is RX gear CVT combination with a 2K-H CVT. To the structural of Conventional CVT’ s design improvements, On the basis of the original transmission speed control, High efficiency, gear ratio for the study of the design goals. And analysis and calculation its theoretical. The results show： the new gearbox drive have high efficiency, wide range, effectively infinitely variable transmission ratio, no closed cycling power phenomenon and no undercutting of phenomenon, and its transmission in speed per-formance and the drive efficiency are better than the original tapered planetary gear transmission. It possesses Promotion of high practical value.
