1, good fuel economy: CVT can realize stepless speed change in a wide range, and can obtain the best matching between transmission system and engine working conditions. Depending on the stepless speed change of the transmission to adapt to the various speeds of the car, the engine can work in the best working condition for a long time, thus improving the combustion efficiency of the engine and improving the fuel economy accordingly.
2. Good power: CVT can realize closed-loop control with the engine, fully mobilize the maximum torque of the engine, and its performance of deceleration and torque increase is obviously better than that of MT and at, so it is assembled on SUV models that need to emphasize torque.
3. Good comfort: CVT can improve driving comfort. CVT has no shift process, continuous linear speed increase, no shift impact, and no AT downshift during rapid acceleration. CVT system has a wide transmission ratio. Generally, when driving at a high speed of 2.400-0.395, the engine speed is low and the noise is low, so that drivers and passengers can enjoy quiet and relaxed comfort during the journey.
Brief introduction to CVT gearbox history
Since 1886 applied for the patent of the first continuously variable transmission, this technology has been improved and improved. Many automobile manufacturers (including General Motors, Audi, Honda and Nissan) are designing power transmission systems around CVT.
The continuously variable transmission is different from the traditional automatic transmission. It has no gearbox consisting of a group of gears, that is, it has no interlocking gears. The most common type of CVT can run on a well-designed pulley system, which can provide infinite variability between the highest gear and the lowest gear without discontinuous steps or gear shifting.
