From the service life of 100,000 kilometers, how big is the gap between CVT gearbox and AT gearbox?
With the continuous development of science and technology, automatic gearbox has been widely used in automobile industry. Among these automatic gearboxes, CVT (continuously variable transmission) and automatic transmission are the two most common ones. In this paper, CVT gearbox and AT gearbox will be compared and analyzed from the point of view of service life of 100 thousand kilometers, and their differences will be discussed.
CVT and AT Introduction CVT gearbox is a continuously variable automatic gearbox, and its structure is mainly composed of and. CVT is characterized by stepless speed change, smooth acceleration or deceleration, and improved driving comfort. However, due to its structural reasons, the torque bearing capacity of CVT gearbox is relatively low and the fuel consumption is relatively large.
AT gearbox is an automatic gearbox with step speed change, which is composed of hydraulic torque converter, and. AT gearbox is characterized by simple operation, good durability and high torque, so it performs better in power transmission. However, the fuel consumption of AT gearbox is relatively high, and the shift process is also slightly frustrated.
Analysis of service life From the service life of 100,000 kilometers, there are some differences between CVT gearbox and AT gearbox.
First of all, from the reliability point of view, CVT gearbox has a relatively low failure rate under the same mileage because of its simple structure. However, because of its complex structure, AT gearbox involves the cooperation of multiple parts, so its failure rate is relatively high under the same mileage.
Secondly, from the performance point of view, CVT gearbox, because of its stepless speed change, makes the vehicle more smooth during acceleration and deceleration, and improves the driving comfort. Although the AT gearbox is easy to operate, there is a sense of frustration in the shift process, which affects the driving comfort.
Details and cases The specific details and cases can better illustrate the performance of CVT and AT gearboxes in actual use. For example, when driving in the city, CVT gearbox makes drivers more relaxed and reduces fuel consumption because of its smooth acceleration and deceleration performance. On the other hand, when driving on the highway, AT gearbox shows its advantages of durability and bearing high torque, which makes the vehicle more stable when driving at high speed.
However, in some specific cases, the performance of CVT and AT gearboxes may change. For example, in the case of large torque, CVT gearbox may slip, which affects its transmission efficiency. In this case, AT gearbox shows better stability and transmission efficiency.
Conclusion Based on the above analysis, we can draw the following conclusions: 1. In the service life of 100 thousand kilometers, CVT gearbox has advantages in reliability and low failure rate; 2. CVT gearbox performs better in driving comfort, and the acceleration and deceleration process is smoother; 3. AT gearbox performs better in bearing high torque, and is suitable for high-speed driving or bearing heavy load; 4. Under different road conditions and driving demands, CVT and AT gearboxes have their own advantages, and the choice should be made according to the actual situation.
Therefore, when choosing an automatic gearbox, consumers should choose the type that suits them according to their actual needs and usage scenarios.
