The mCVT transmission uses a toroidal architecture which offers smooth, seamless shifting with no steps through an infinite number of speeds. The infinite number of ratio enables the engine to operate at or close to its “sweet spot” therefore driving significant fuel economy. The CVT also makes construction equipment easier to drive, safer, more productive and due to its high efficiency, provides the OEM’s with the opportunity to downsize engine. Using a smaller engine and potentially cheaper emission after-treatment result in major system cost reduction for the OEM’s.

The mCVT efficiency compares very favorably to other types of transmission:

When compare to a powershift with torque converter, the efficiency is better AND enable using the engine at its most efficient point, which increases fuel economy.

Compared to other CVT’s such as a hydrostatic transmission, the efficiency is 15-20% better and is similar or better than hydromechanical CVT’s typically used on large equipment and agricultural tractor while being much more cost effective.

Our traction drive CVT is both powerful and fuel efficient by design. With a very low parts count, power is not wasted through parasitic losses due to excessive gearing, hydraulics and numerous clutch packs.

Efficiency is achieved by transferring torque and power from the input (end) discs to the output (center) disc through 6 actuated rollers. No metal to metal contact occurs as the specially formulated traction oil used in the transmission is trapped at each contact point between rolling element surfaces. The pressure at contact points induces a phase change in the oil which then momentarily becomes visco-elastic, allowing torque to be transferred without slippage.
