    • Embodiments are directed to a front end accessory drive (FEAD), subassemblies, and components therefor. Embodiments disclosed cover power modulating devices (PMD) which can be used in a FEAD. In one embodiment, a continuously variable transmission (CVT) is coupled directly to a crankshaft of a prime mover, and the CVT is used to regulate the speed and/or torque delivered to an accessory. A compound drive device includes a motor/generator subassembly cooperating with a CVT subassembly to provide a motor functionality with torque multiplication or division, or alternatively, a generator functionality with torque multiplication or division. In some embodiments, a FEAD includes a PMD having a sun shaft configured to couple to a sun of the PMD and to an electric motor component, such as an electrical armature or an electrical field. In one embodiment, the electrical armature the electrical field are placed concentrically and coaxially and configured to rotate relative to one another in opposite directions.
    • 实施例涉及前端附件驱动(FEAD),子组件及其部件。 所公开的实施例涵盖可用于FEAD中的功率调制装置(PMD)。 在一个实施例中,无级变速器(CVT)直接联接到原动机的曲轴,并且CVT用于调节传递到附件的速度和/或扭矩。 复合驱动装置包括与CVT子组件协作的电动机/发电机子组件,以提供具有扭矩倍增或分配的电动机功能,或者可选地,具有扭矩倍增或分配的发电机功能。 在一些实施例中,FEAD包括具有太阳轴的PMD,该太阳轴被配置为耦合到PMD的太阳和电动马达部件,例如电枢或电场。 在一个实施例中,电枢电场被同心地且同轴地放置并且被配置成在相反的方向上相对于彼此旋转。
