What is the Difference Between CVT and Automatic Transmission?
2 Answers
The difference between CVT and automatic transmission lies in the gear configuration and structural design. Most cars currently use either manual or automatic transmissions, where the drive chain and shifting principles are similar to those of a bicycle, involving gear-set shifting that results in noticeable jerking during gear changes. Below is a detailed comparison of the two: 1. Gear Configuration: CVT only shows directional changes like forward or reverse, while automatic transmission converts the shifting direction of manual transmission into a linear motion. 2. Structural Design: CVT lacks the multiple gears of a manual transmission, whereas automatic transmission retains the multiple gears of a manual transmission.
When it comes to the difference between CVT and automatic transmissions, I believe the principle is the core. CVT uses a set of pulleys and a belt to transmit power, unlike conventional AT which relies on gears for shifting; CVT allows for continuous changes in speed, making the drive exceptionally smooth without any shifting jerks. However, automatic transmissions (AT) have fixed gears, such as 4-speed or 6-speed, and switch via a torque converter, occasionally making the shifting noticeable during driving. The advantage of CVT is more pronounced in urban areas, as the engine can always maintain the optimal speed for fuel efficiency; the downside is that the belt may wear out or age, leading to noise over time and potentially higher maintenance costs. Automatic transmissions (AT) are mature in technology and cheaper to repair, but they are less efficient than CVT, especially in traffic jams where fuel consumption is slightly higher. If you drive long distances, AT performs steadily on highways; CVT is more suitable for city commuting, prioritizing comfort.
