Lifts the double clutch gearbox, may be mostly thinking of the public in the first time, because in 10 years ago, it is the advantage of the public to promote turbocharged + double clutch, which makes consumers for automobile power assembly. Cognition is no longer limited to the traditional natural inhale + AT transmission, thereby paving the way for other vendors. However, it has taken someone else, and the public has dropped into the pit. Due to the lack of research on domestic road conditions, the early dry double clutch can be called the whole army, and the problems such as falling, abnormal sound, and power discontinuation have always plagued the public. The first few of the monthly complaints on the list of complaints can see the quality of the double clutch gearbox, and even the “3.15 party” is also boarded.
Although it comes back, although the dry dual clutch gearbox is caused by major setbacks, we can still see the public today. Many of its entry compact sedan or SUV continue to adopt DQ200’s dry dual-clutch gearbox, and the sales performance of each car is very good, then this is to mean that today’s dry dual-clutch speed box is worth buying. ?
Before the value is not worth buying, you may wish to first understand the working principle of the double clutch transmission. In fact, the dual-clutch gearbox can be understood as a combination of two manual gearboxes, in other words, there are two clutches, during the working process of dual-clutch, and another clutch is ready to prepare the next gear. Therefore, the transmission efficiency of the double clutch transmission is relatively high, and the shift speed is faster than the general AT and CVT. This also explains why the mass engine horsepower does not occupy, and the accelerated performance of 100 kilometers is still in the same level. The reason for the first echelon. However, behind the extremely high transmission efficiency is achieved by the change of shifts.
Due to the inside lack of a liquid torque converter for a buffer, an overheating occurs when the low speed is frequently liter, and then accelerate the clutch The film wear, the serious situation will occur, and the power transmission is interrupted, and it will return to the factory. In this regard, the public develops a wet double clutch gearbox, soaking the clutch tablets in the lubricating fluid, help to reduceA series of problems that have been overheated, but they are subject to cost, wet double clutch generally only appear in its 200,000-priced model, and the market has a very large Sagitar, LaVida, Bora, etc. entry-level compact cars, Dry dual-clutch gearbox is still used.
Combined with its own car environment
Since the dry double clutch gearbox stability is lacking, it is not What should we avoid this type of model when we buy a car? Regarding this problem, it is actually divided into two sides. If you live in urban traffic conditions are not very congested, or the daily car environment is concentrated in high-speed, urban expressway, such as a small number of vehicles, and the speed of speed, and there is no problem with the dry dual clutch gearbox. Because there is no low-speed frequency plus downstream. And if you use the car environment to get off work, you have to experience the morning and evening peak every day, then it is recommended to be cautious. Although the clutch overheat can use the manual mode to fix the gear, but this is a bit like the sense of treatment.
Don’t put a mistake when it is permanent
, if you want to pursue the ultimate acceleration experience in the case of limited budget, So dry double clutch can be selected, from the product, the DQ200 is not 10 years ago, the DQ200 of the problem is like the EA888 engine, although the second generation of burning oil is very serious, but after the improved piston After the ring, the third generation has no large-area burnt oil, the DQ200 is the same, after years of improvement, its stability and changing will not be in the same day, in addition to the very low speed Outside of the impact, all other aspects are very good.
Summary 
Synthetic, dry double closing is not to buy, but only require a specific use environment and for the car Knowledge has a certain understanding, but this is a little higher for ordinary consumers, so if you just want to buy a pediced home car, then it is recommended that you choose a tradition.The AT gearbox or CVT gearbox is more secure.
