When we are shopping for a car, the choice of transmission becomes an important issue. CVT gearboxes and AT gearboxes, as two of the most common types of gearboxes on the market, each have unique advantages. So, which gearbox is more durable?Let's follow in the footsteps of the old driver and work together to ** this question. CVT gearbox: a smooth and economical representativeCVT gearbox, also known as continuously variable gearbox, is characterized by smoothness and economy. The CVT gearbox achieves continuously variable gearing through a combination of steel belts and pulleys, which means it can maintain an optimal rev ratio at any speed, resulting in smoother acceleration and more economical fuel consumption. Specifically, a CVT gearbox works by changing the gear ratio by changing the distance between the pulleys. This design allows the CVT transmission to maintain the best rev ratio at any speed, resulting in smoother acceleration and more economical fuel consumption. In addition, CVT gearboxes also have the advantages of simple structure, light weight and small size, so they are widely used in small cars and compact cars. However, the CVT gearbox also has its drawbacks. Due to its structural characteristics, CVT gearboxes are prone to slippage when subjected to high torques, which leads to a shortened life of the gearbox. In addition, the repair cost of CVT gearboxes is relatively high. Therefore, if you have a driving requirement that requires frequent high torques or high maintenance costs, then a CVT transmission may not be the best choice. AT gearbox: the epitome of stability and durabilityAT transmission, also known as automatic transmission, it achieves shifting through a torque converter and a planetary gear set. Compared with CVT gearbox, AT gearbox is more stable and durable. It can withstand more torque and still maintain a stable RPM ratio at high speeds. The advantage of an AT gearbox is its stability and durability. Due to its structural design with torque converter and planetary gear set, the AT gearbox can withstand high torque without slippage. This allows the AT transmission to maintain consistent performance in all driving conditions. In addition, the repair cost of the AT gearbox is relatively low, as it has a relatively simple construction and has been improved and optimized over the years.
The gap after 80,000 km: Durability is instantaneousWhen the CVT and AT transmissions have traveled 80,000 km, the durability gap between them becomes even more pronounced. Due to the structural characteristics of the CVT gearbox, it is prone to slippage when subjected to high torque, which will lead to a shortening of the life of the gearbox. As a result, after 80,000 km, the CVT gearbox may need to be replaced or repaired. The AT gearbox, on the other hand, can maintain good performance after 80,000 kilometers due to its stable and durable characteristics. While it may be slightly less smooth and economical than a CVT gearbox, the stability and durability of an AT gearbox will make it a more economical option in the long run. Specifically, the planetary gear set structure of the AT gearbox gives it greater strength and durability, capable of withstanding greater torque and higher speeds. The use of torque converters ensures the smooth transmission of power and smooth gear changes. Therefore, in long-term use, the performance of the AT gearbox decays relatively little and has a longer service life.
Conclusion: To sum up, CVT gearboxes and AT gearboxes have their own advantages and disadvantages. The CVT gearbox has the advantages of ride and economy, making it suitable for driving in the city and on the highway;The AT gearbox, on the other hand, has the characteristics of stability and durability, and is suitable for use in harsh road conditions and heavy load conditions.
