A CVT, or continuously variable transmission, is a type of automatic transmission that uses two cone-shaped pulleys connected by a belt or chain instead of traditional fixed gears. This design allows the transmission to change through a continuous range of gear ratios, providing smooth, stepless gear changes without the jolting shifts typical of conventional automatic transmissions
. Key features of a CVT include:
- Infinite gear ratios: Unlike traditional transmissions with a fixed number of gears, a CVT can vary its gear ratio seamlessly to keep the engine operating at optimal RPM for power or fuel efficiency
- Pulleys and belt system: The two pulleys adjust their effective diameters by moving halves closer or farther apart, which changes the belt's position and thus the gear ratio continuously
- Fuel efficiency: By maintaining the engine at its most efficient speed, CVTs often improve fuel economy compared to traditional automatics
- Smooth driving experience: The absence of discrete gear shifts results in a smooth ride without the typical shift shock
CVTs are commonly found in compact, fuel-efficient vehicles rather than high- performance cars, as they prioritize efficiency and smoothness over sporty driving feel
. In summary, a CVT is an automatic transmission system that continuously adjusts gear ratios using pulleys and a belt or chain, optimizing engine performance and fuel economy while providing a smooth driving experience
