What does ECVT continuously variable transmission mean?
1 Answers
CVT continuously variable transmission, as the name implies, does not have specific gears. In operation, it is similar to an automatic transmission, but the change in speed ratio differs from the gear-shifting process of an automatic transmission, instead providing continuous speed variation, thus ensuring smooth and uninterrupted power delivery. Advantages and disadvantages of CVT transmission: 1. Since it lacks the transmission gears of a conventional automatic transmission, there is no gear-shifting process, eliminating the associated jerky shifting sensation. As a result, the power output of a CVT transmission is linear, providing a very smooth driving experience. 2. The transmission system of a CVT theoretically allows for an infinite number of gears, offering greater flexibility in gear settings. It is easier to achieve a balance between gear ratio, speed ratio, performance, fuel consumption, and exhaust emissions compared to traditional transmission systems. 3. The mechanical efficiency and fuel economy of CVT transmission are significantly better than those of conventional automatic transmissions, second only to manual transmissions, resulting in much better fuel efficiency. 4. Compared to traditional automatic transmissions, its cost is slightly higher; moreover, improper operation increases the likelihood of issues. 5. The CVT transmission itself has its drawbacks, primarily that the steel belt used in transmission can only withstand limited force.
