Abstract:

The Phase II will continue development of a continuously variable transmission (CVT) that utilizes magnetorheological (MR) fluids. The Phase I program investigated several CVT concepts and defined a design and control approach for a 50 hp CVT that fitswithin the space available (10-inch dia x 3-inch long) in a wheel. The Phase I will conclude with test of a small-scale MR fluid transmission now under development. The Phase II will develop a full-sized CVT engineering prototype, integrate it with a drivemotor, install it on SatCon's dynamometer, and measure key performance parameters. Subsequently, a second prototype, consisting of an in-wheel CVT and a separate CVT control unit, will be developed at SatCon. This in-wheel CVT prototype, suitable for testin an ARL research vehicle or test stand, will possess the necessary interfaces for integration with the wheel and motor: coolant, electrical power/signal connections, proper space envelope, and mounting. The in-wheel CVT and control unit will beintegrated with an in-wheel motor for the ARL research vehicle and tested at SatCon's dynamometer facility prior to delivery to ARL. The control unit, housed in a small electronics enclosure, shall require available vehicle power, a speed reduction commandsignal from the driver or vehicle control unit, and input/output speed feedback, in order to control the CVT.
