  • Variable-Reluctance Sensors
    controls, and antilock-braking systems. Variable-reluctance (VR) sensors work well for these automotive applications because
  • 2002 Audi A4 1.8T CVT
    I wanted to test the continuously variable transmission (CVT) Just in case you can't decipher Audi's code for naming vehicles, the car I tested was an A4 with the 1.8-liter turbocharged engine and continuously variable transmission. It's a great little sedan, and I use the term a little bit loosely
  • Two modes are better than one for heavy-duty hybrids
    , " in this context, describes the configuration of transmission gearing for optimal efficiency at varying speeds and power levels. Unlike conventional continuously variable transmissions, the 2-Mode full hybrid 's electrically controlled system uses no mechanical belts or bands. Shifts between modes are synchronous
  • Better metals for modern cars
    , with special electrical or magnetic properties. Additionally, advances such as camless valve trains, and continuously variable-transmissions will demand much of alloys. Steel makers continue to keep pace with a lot of new ideas. Stainless steels are about 50% stronger than lowcarbon steels. Their high

    converter, say company officials. WinDrive is the first variable transmission for wind-turbine drivetrains without a frequency converter. It is based on a hydrodynamic converter combined with a superimposing planetary gear stage. The system converts fluctuating turbine-rotor inputs into a constant
  • April 21, 2009 - Wind-turbine drive takes the prize at Hannover Fair
    generators, variable wind speed needs to be converted to a constant output speed. The WinDrive system is the first dynamic variable-transmission applied to the drivetrain of a wind turbine without a frequency converter. The drive system is based on a hydrodynamic converter in combination
  • 2005 Mercury Montego Premier AWD
    After a few miles in the Mercury Montego, I recalled that Ford had been considering a continuously variable transmission for it. Did this model have one? It didn't feel any different than what was expected push on the gas and it goes. The tach would rise and fall during accelerations, so I assumed
  • 2007 Nissan Sentra 2.0 S
    still have to turn the ignition, but as long as the fob is inside the vehicle, you don 't need the key.) The continuously variable transmission, hitched to a 2.0-liter DOHC four-cylinder engine, is super smooth and surprisingly responsive. The Sentra can also be ordered with a six-speed manual
  • 2009 Dodge Caliber R/T
    . The 2.4-liter engine, paired with a continuously variable transmission, was good for 172-hp @ 6,000 rpm and 165 lb-ft torque at 4,400 rpm. The Caliber handles nicely and its sport-tuned suspension and 18-in. alloy wheels give it a nice smooth ride. The Caliber's Mopar premium coilover suspension kit
  • Gear Drives
    The most reliable means for changing shaft speed remains a mechanical variable-speed transmission. These drives are used to provide a variable output speed from a constant-speed power source (as in a machine tool driven by a constant-speed ac motor) or to provide torque increase

  • Automotive Transmissions
    This has also lead to a massive diversification among transmission designs, with individual solutions and competing concepts: manual transmissions (MT), automated manual transmissions (AMT), dual clutch transmissions (DCT), conventional automatic transmissions (AT), continuously variable transmissions (CVT) and hybrid drives.

  • The Automotive Transmission Book
    In the 1990’s transmission technology—especially the step automatic transmissions— was challenged by the introduction of continuous variable transmissions for higher torque applications.
