NSK Develops a Highly Efficient Toroidal Variator Module for Front-wheel Drive Automobiles
NSK Ltd. (NSK; Headquarters: Tokyo, Japan; President and CEO: Norio Otsuka) today announced that it has developed the world's first*1 toroidal variator1 for use in front-engine, front-wheel drive (FWD) vehicles. The new product surpasses both the multi-step automatic transmission (AT) and the belt-drive continuous variable transmission (CVT) in fuel economy.
NSK will exhibit this product at Tokyo Big Sight (located in Koto Ward in Tokyo) from Wednesday November 30 to Saturday December 11 at the Tokyo Motor Show 2011.
*1 as of November 2011 (NSK Ltd.)
*2 Toroidal variator: A transmission that enables continuously variable shifting without a speed changing gear. It provides a smooth ride and improved fuel economy because it avoids clunky or lurching gearshifts by maintaining the transmission in the optimum gear ratio for engine speed. NSK's new toroidal variator has a wider gear ratio coverage and better efficiency than the toroidal CVT.
