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 method for modulating power to an accessory in a vehicle using a controller with logic, the method comprising: receiving, from a sensor, a signal associated with a power output by a prime mover; comparing the signal with a desired input speed for an accessory; and adjusting the speed provided by the prime mover to a speed required by the accessory using a power modulating device, wherein the power modulating device includes a housing, a variator in th…
