Fallbrook Technologies Inc., a technology company in the area of transmissions for vehicles and equipment, has entered a memorandum of understanding (MOU) with TRW Automotive U.S. LLC, a subsidiary of TRW Automotive Holdings Corp. Under terms of the MOU, Fallbrook and TRW will explore the development of a number of possible applications for Fallbrook’s NuVinci continuously variable accessory drive (CVAD) technology for commercial vehicles, which is designed to optimize the performance and efficiency of engine-driven accessories such as the alternator, air-conditioner, water pump, and power steering. The NuVinci technology uses a set of rotating and tilting balls positioned between the input and output components of a transmission; tilting the balls changes their contact diameters and varies the speed ratio. The specific applications covered by the MOU were not disclosed. The companies will continue to investigate development of these applications with the possibility of entering a definitive joint development agreement, the negotiation of which is expected to conclude in 2011.
