VariGlide® is completely scalable across all vehicle platforms.
Dana's VariGlide® technology is bringing higher performance to beltless CVTs
Dana’s innovative new concept for the light-vehicle market, VariGlide® planetary variator technology, is revolutionizing traditional transmissions. Featuring a unique planetary configuration in combination with conventional gearing, the VariGlide concept is an optimal solution for OEMs to meet future fuel efficiency targets and emissions regulations on a variety of light vehicles, including passenger cars, SUVs, CUVs, and pickup trucks. Incorporated into the existing packaging space of a standard automatic transmission, VariGlide technology is an enhanced alternative to dual clutch transmissions, multi-speed automatics, and conventional belt CVTs.
10 percent improved fuel economy over belt CVTs
Greater durability than belt CVTs
Exceptional drivability and smooth shifting
FWD, RWD, and AWD applications
Responsive engine operation
Reduced engine wear and complexity
Planetary Variator Configuration
VariGlide technology provides unparalleled powerpath flexibility through a unique variator design configuration. A set of spinning balls is fitted between an input disc, driven by the engine, and an output disc, which transfers power from the variator to the drive axle. As power enters the input disc, the balls shift on their axes and change contact ratios, depending on engine demands and controller input. This allows the VariGlide variator to provide shifting that is smooth, fast, and controlled.
To efficiently transfer torque, a thin layer of traction fluid flows between the balls. This traction fluid becomes momentarily rigid, allowing the torque to transfer between the balls and discs without slipping. With numerous powerpaths and no abrupt ratio changes, VariGlide technology provides an infinite number of gear ratios for improved shifting, driver comfort, and even greater efficiency when compared to automatic transmissions and CVTs.
