Why is the CVT transmission so smooth?
3 Answers
Because the CVT transmission is a continuously variable transmission, this type of transmission does not have fixed gears. The process of changing speed and torque is continuous, so there is no jerking, making it very smooth. Here is a detailed introduction to the CVT transmission: 1. The structure of the CVT transmission is very simple. It consists of two cone-shaped pulleys and a steel belt inside. The steel belt can move on the pulleys, allowing the transmission to vary speed and torque. Conventional transmissions have different gear sets, and the gear ratio span in these transmissions is larger than that of a CVT, resulting in jerking after gear shifts. 2. Conventional transmissions are like climbing stairs, where each step represents a gear. Transmissions with more gears have smaller step heights, reducing jerking. Transmissions with fewer gears have higher step heights, leading to more noticeable jerking during shifts. In contrast, the CVT transmission replaces the stairs with a smooth ramp, which has no steps, giving the CVT excellent smoothness.
As a seasoned driver with 30 years of experience, I can explain why CVT transmissions are so smooth. It's because they don't have any gear structures at all. Traditional automatic transmissions rely on gear shifts, and every gear change feels like a kick in the pants. CVTs use a pair of conical pulleys and a steel belt (or chain) system, sliding like a bicycle gear shifter, allowing the gear ratio to change seamlessly and continuously. This means no jerking during acceleration—just step on the gas, and the car moves forward smoothly, with the engine RPM staying steady, saving fuel and providing comfort. I especially love it in city traffic jams; it doesn't hesitate like dual-clutch transmissions. Toyota commonly uses CVTs, and after driving a Corolla for ten years, its smoothness has never let me down. The downside is slightly weaker power response during high-speed overtaking, and the belt is prone to wear, requiring regular maintenance. Overall, it's perfect for relaxed driving—gliding along effortlessly like skating.
Driving a car with a CVT feels absolutely amazing! With my old manual transmission, every gear shift came with a jerk, but now my Civic accelerates seamlessly, as if riding on a cushion of air. The CVT operates using two pulleys and a metal belt, constantly adjusting the ratio during gear changes, keeping the engine sound smooth and continuous. Traditional automatic transmissions jerk with every shift, but the CVT completely avoids this, letting you focus on driving. I've also driven my friend's Audi with a CVT, which was even smoother with its hybrid system, making it both economical and practical. In traffic jams, its advantages shine even more—so smooth you forget about the frustration of jerky shifts. The downside is that some cars might respond a bit slower at high speeds, but for daily commuting, it's perfect. Just remember to change the oil on time, and the belt's lifespan will be extended.
