摘要

提出一种新型结构的卡盘式变径带轮无级变速器，该新型无级变速器（CVT）在传动上使用卡盘式变径带轮与多楔带相结合的带传动方式，实现了带轮与传动带的面接触式摩擦传动。推导了卡盘式变径带轮传动的有效圆周力计算公式，并分析了卡盘式变径带轮最大有效圆周力的变化规律，验证了卡盘式变径带轮具有大转矩的传动能力。另外，进行了基于Adams的卡盘式变径带轮传动动力学仿真，研制出卡盘式变径带轮无级变速器实验装置，进行了实际运行测试。结果表明，该新型CVT传动速度平稳，满足车辆使用要求。

Abstract

A new structure of chuck-type adjustable radius pulley continuously variable transmission (CVT) is proposed. The new CVT uses the belt drive mode of the combination of the chuck-type adjustable radius pulley and the multi-wedge belt in the drive, and the face contact friction drive between the pulley and the drive belt is realized. The calculation formula of the effective circumferential force of the chuck-type adjustable radius pulley drive is deduced, and the variation law of the maximum effective circumferential force of the chuck-type adjustable radius pulley is analyzed, which verifies the drive ability of the chuck-type adjustable radius pulley with large torque. In addition, the dynamics simulation based on Adams is carried out, and the experimental device of chuck-type adjustable diameter CVT is developed to test and verify. The results show that the drive speed of the new CVT is stable and meets the requirements of vehicle use.
