An example prototyped as a bicycle transmission was patented in 1994. [19] The operating principle for a ratcheting CVT design, using a Scotch yoke mechanism to convert rotary motion to oscillating motion and non-circular gears to achieve uniform input to output ratio, was patented in 2014.
A continuously variable transmission (CVT) can change seamlessly through a continuous (infinite) range of gear ratios, compared with other automatic transmissions that provide a limited number of gear ratios in fixed steps. The flexibility of a CVT with suitable control may allow the engine to operate at a constant angular velocity while the ...
A continuously variable transmission (CVT) can change seamlessly through a continuous range of gear ratios. This contrasts with other transmissions that provide a limited number of gear ratios in fixed steps. The flexibility of a CVT with suitable control may allow the engine to operate at a constant RPM while the vehicle moves at varying speeds.
Continuously variable transmissions are an automotive transmission fitted in a vehicle, using a continuously variable drive ratio or variator device. The typical "automatic gearbox" is not usually considered to be a continuously-variable transmission, as it relies on shifting between discrete gear ratios.
Variomatic is the continuously variable transmission (CVT) of the Dutch car manufacturer DAF, originally developed by Hub van Doorne. [1] It is a stepless, fully- automatic transmission , consisting of a V-shaped drive-belt, and two pulleys , each of two cones, whose effective diameter can be changed so that the "V" belt runs nearer the spindle ...

The K110 was Toyota's first belt-type CVT and production began in August 2000. Toyota said that the transmission was both fuel-efficient and offered high driving performance. The K110 features a torque converter with a long-travel damper to help achieve quiet operation and improved fuel efficiency. Applications: Toyota Opa – 2.0L (2000–2005)
