Abstract
Official abstract text for this publication.
Embodiments are directed to a front end accessory drive (FEAD) and 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.
First claim
Opening claim text (preview).
What we claim is: 1. A power modulating device comprising: a plurality of spherical planets; a sun in contact with the spherical planets; an electrical armature operably coupled to the sun; an electrical field mounted coaxially about and concentrically with the electrical armature; and first and second traction rings in contact with the plurality of spherical planets, wherein the electrical armature and the electrical field are configured such that both the electrical arma…
