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 mechanical CVT not only offers the best peak efficiency (up to 94%) available on the market but it also maintains industry leading efficiencies regardless of input power. Unlike other types of transmissions that are optimized to work in specific narrow power ranges, the traction drive design maintains its efficiency over the complete power and speed range.
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.
Over 500,000 hours of testing in laboratories and real-life applications by OEMs (Original Equipment Manufacturers) and CVTCORP.
– Over 200 units tested in the field
– 25,000 hours accelerated life test
Internal testing and in-field experience have led to the development of today’s transmission and in achieving the level of reliability required by the industry. Our facilities can also perform accelerated testing in harsh environments that exceed industry standards and performance criteria. We are constantly researching new designs to improve our software, efficiency and configurations.
Electrification Motor and Drive Downsizing
Superior Performance with Software
One Variator, Multiple Designs
The right technology for today and tomorrow
Electrified powertrains either hybrid or full electric are getting rapid acceptance in the off-highway market. With the torque multiplication of the CVT then, there is a great opportunity to optimize the full e-powertrain and properly size motors, generators, inverters, batteries and battery management system resulting in smaller packages, enhanced range and reduced cost.
