CEDAR PARK, TX--(Marketwired - March 14, 2017) - Fallbrook Technologies Inc., the inventor of the NuVinci continuously variable planetary (CVP) transmission technology, today announced that NuVinci technology is included in the latest edition of the influential and widely used mechanical engineering textbook, "Fundamentals of Machine Component Design 6th Edition," by Robert C. Juvinall and Kurt M. Marshek, published by Wiley. This is the first edition of the textbook to include a section on traction drives, which includes NuVinci technology. The textbook includes a diagram showing a NuVinci CVP and a link to more traction drive information available in a newly created section on Fallbrook's website at www.fallbrooktech.com/traction-drives.
NuVinci technology combines the time-proven versatility of the planetary gear arrangement with the advantages of seamless shifting in a continuously variable transmission (CVT). Just like a planetary gearset, it can split or sum power, or step speed and torque up or down. However, unlike traditional planetary gearsets, the NuVinci CVP can also vary the speed and torque of the power it is transmitting through an infinite set of ratios within its range, thereby providing a whole new set of solutions for engineers looking to optimize the efficiency of their systems in both cost and system level performance.
Acknowledging the significance of the inclusion of the NuVinci technology in the publication, Jeremy Carter, Fallbrook's vice president of product development, notes that "for the first time, a widely used textbook for mechanical engineering students discusses traction drives, including the NuVinci CVP. This acknowledges traction drive CVTs as an accepted and recognized element of mechanical system design, just as gears have been for centuries. NuVinci is a platform technology and is suitable for a broad range of applications."
Since its incorporation in 2004, Fallbrook and its community of licensees from major industry players have invested hundreds of millions of dollars in the development of the technology. Last summer, Dana Incorporated presented its VariGlide® CVP variator using the NuVinci technology at the International VDI Wissenforum Conference in Friedrichshafen, Germany, and VanDyne Superturbo Inc. recently selected the technology for its next generation of variable speed SuperTurbo™ drives. Allison Transmission has licensed NuVinci for medium- and heavy-duty applications, while TEAM Industries has licensed it for light off-road and on-road applications. Additionally, Continental has adopted NuVinci technology for its urban mobility initiatives.
"The NuVinci CVP provides the most adaptable, scalable, and affordable CVT available today for companies that need a cost effective, easily controlled, and durable alternative to conventional transmissions or other CVTs," said William G. Klehm III, Fallbrook's chairman and CEO. "The NuVinci CVP can also be used as a variable planetary drive in virtually any mechanical device and is far simpler, offers more stable control, permits more scalability across product lines, is easier to package, and is less expensive to manufacture and assemble." Since the invention of NuVinci technology, Fallbrook and the community of NuVinci licensees have developed and are developing numerous enhancements including support for faster shifting and increased power handling.
Included in the attachment below is additional information about the benefits of the NuVinci technology. Further information is available on the Fallbrook Technologies website: www.fallbrooktech.com.
The Juvinall and Marshek textbook is currently available directly from the publisher (Wiley) and will soon be available on Amazon and other booksellers.

Additional Information on NuVinci® Technology
The planetary configuration provides the CVP inherent advantages over other traction CVTs described in the textbook.
- Designs incorporating NuVinci technology can potentially improve efficiency without sacrificing performance and vice-versa.
- Unlike toroidal CVTs, the NuVinci CVP distributes the transmitted torque over several spheres in an inherently stable configuration, thus lowering total clamping force required and significantly improving durability, control stability, and torque density.
- This not only provides enhanced traction characteristics when looking at the entire variator, but it also provides design robustness and reliability required by the transportation and mechanical industries at an affordable cost and uncompromising package size -- separating it from the rest of the class of traction CVTs.
- The NuVinci CVP reduces energy consumption through its continuous speed changing characteristics, allowing the power input prime mover (such as a gasoline engine or electric motor) to operate in its most efficient speed range.
- Overall, the NuVinci CVP's mechanical and manufacturing characteristics improve performance and reliability while reducing costs over conventional CVTs and stepped transmissions. As a result, it can potentially replace the planetary gear transmission in most mechanical devices.
