    • The present invention provides a continuously variable belt pulley transfer system that addresses prior deficiencies with CVT -type systems, particularly when used with accessory drive systems. The continuously variable belt drive system includes a driving pulley assembly and a driven pulley assembly, with a continuous belt transferring rotary motion between them. A direct electronic actuation mechanism is used for controlling ratio changes on the pulley transfer assembly. An integrated stepper motion is used as the prime mover for the mechanism. A differential planetary roller screw mechanism converts the rotary motion from the stepper motor to axial motion for actuating the sheave poison of the V-shaped belt.
    • 本发明提供了一种连续可变的皮带轮传动系统,其可以利用CVT型系统解决先前的缺陷,特别是当与附件驱动系统一起使用时。 无级变速皮带传动系统包括驱动滑轮组件和从动滑轮组件,连续皮带在它们之间传递旋转运动。 直接电子致动机构用于控制皮带轮传送组件上的比例变化。 集成步进运动用作机构的原动机。 差速行星滚子丝杠机构将来自步进马达的旋转运动转换为轴向运动,以致于V形皮带的滑轮中毒。
