What is a Continuously Variable Transmission?
2 Answers
Continuously Variable Transmission (CVT) is a type of transmission system that can continuously obtain any gear ratio within the transmission range, allowing the drivetrain to be optimally matched to the engine's operating conditions. CVTs are commonly found in Japanese car models. The advantages of this type of transmission include smooth operation, as there is no noticeable gear shift shock during operation, which helps improve driving and riding comfort. Unlike traditional transmissions, a CVT does not have a gear-driven structure inside. Instead, it uses two variable-diameter pulleys connected by a belt to transmit power.
CVT? I've studied it before, it's a type of automatic transmission but unlike traditional ones with fixed gears. The core mechanism uses a belt and pulley system; the diameters of the two pulleys can vary continuously, allowing seamless power transfer from the engine to the wheels. The advantage is exceptionally smooth driving without the jerky feeling during gear shifts like conventional automatics, with acceleration as smooth as an electric vehicle, plus better fuel efficiency – in my experience, you can squeeze out a few extra kilometers in city driving. However, there are drawbacks: some complain about a droning sound during acceleration, like a rubber band stretching, and prolonged high-load driving might affect reliability. Maintenance requires regular changes of specialized transmission fluid and belt inspections, making upkeep slightly costlier. Overall, it's widely used in Japanese cars and suits regular drivers who prioritize comfort.
