Many friends will care about one question when buying a car: what gearbox is the car carrying? Many people have also heard that the quality stability of dual-clutch gearbox is poor and the failure rate is high. Now it is recognized that the better gearbox is at gearbox, so is at gearbox really better than dual-clutch gearbox? Old driver: You can see it at a glance after comparison.
I comparison of advantages and disadvantages between AT gearbox and dual clutch gearbox
1. The service life of AT gearbox is longer.
Here, the structural principles of two gearboxes need to be involved. at gearboxes generally use hydraulic torque converters, while dual-clutch gearboxes generally use clutch plates. The biggest structural difference between them lies in whether the internal parts are directly connected together, which is generally called rigid and non-rigid.
Due to the internal structure, the wear of dual-clutch gearbox is much greater than that of at gearbox. Generally speaking, At gearbox can run more than 100,000 kilometers, and even does not need overhaul.
However, the dual-clutch gearbox stops and goes under the crowded roads in modern cities, and the gear shifting times are more, and the wear times are also more. Generally, the gearbox needs to be repaired when it runs less than 100,000 kilometers, or the clutch plates need to be changed, so the service life of the dual-clutch gearbox is lower than that of the at gearbox.
2. The AT gearbox has better stability and lower maintenance cost.
In fact, it is also related to the internal structure, one is non-rigid connection, the other is rigid connection, and the later maintenance cost of at gearbox is relatively low, and the gearbox oil is generally changed. As long as the owner maintains it well and there is not too much violent driving in normal use, there will basically be no major failures.
For the dual-clutch gearbox, frequent shifting will lead to serious internal wear. If the overhaul is expensive, the dual-clutch gearbox is different from the manual gearbox. If the manual gearbox is broken, it may only be better to replace a certain component or clutch plate, while the dual-clutch gearbox may need to replace a whole set of parts.
Although the dual clutch gearbox is more fuel-efficient, the later maintenance costs may also offset the saved oil money. It is not that the dual clutch cannot be purchased, but that you need to pay more attention when driving, try to avoid violent driving, and switch to manual mode when traffic jams occur.
Second, AT gearbox has a better reputation.
The origins of the two gearboxes can be traced back to a hundred years ago, but the development trajectories are not quite the same. After the invention of at gearboxes, people have been constantly optimizing and improving them, and this is also the case today. The dual-clutch gearbox was not widely used when it appeared in the market, but it began to be widely used 30 or 40 years ago.
Therefore, the stability of at gearbox will be higher and more mature, while the transmission efficiency of dual clutch gearbox is high, but compared with durability and economy, at gearbox may have more advantages.
There has been data analysis before, saying that statistics and opinions on automobile gearboxes are summarized. Seven of the top ten gearboxes with the highest complaint rate are dual-clutch gearboxes, and only one of them is at gearboxes. Therefore, compared with word of mouth, at gearboxes may be better.
No matter what kind of gearbox has its advantages and disadvantages, the most important thing is that the owner avoids violent driving and develops good driving habits when driving, so as to prolong the life of the gearbox and reduce the maintenance cost. Both gearboxes have been improved and optimized by the market for many years, and the key lies in the quality of driving habits.
