摘　　要：研究了一种高效率、大功率的无级变速器,其主要由变径带轮无级变速传动和行星差动轮系传动组成。通过变径带轮传动与行星传动组合,可以实现多路传动和功率汇流;通过行星差动轮系两个输入转速自由配比,可以调节功率汇流比例。该机构具有结构简单,传动功率大、传动效率高、工作平稳等特点。A high-efficiency and high-power continuously variable transmission(CVT)is studied,which is mainly composed of variable-diameter pulley stepless speed change transmission and planetary differential gear train transmission.Multi-channel transmission and power convergence can be realized through the combination of variable-diameter pulley transmission and planetary gear transmission,and the ratio of power convergence can be adjusted through the free ratio of two input speeds of planetary differential gear train.The mechanism has the characteristics of simple structure,high transmission power,high efficiency transmission and stable operation.
