Buying a car is a multiple-choice question with another multiple-choice question. The more questions you do, the better, and the higher your final score will be. The average person will probably pick the brand, face value, model, and space, but the person who really understands the car will definitely ask one more question: What transmission is used in this car?
Is the transmission important? Of course, apart from the difference between automatic and manual transmissions, it also directly affects the fuel consumption of the car, the shifting time, and the quality of the power output. Is there any sense of frustration?
Manually save fuel but operate inconveniently, AMT gearbox is economical but has poor experience, AT is convenient but fuel consumption is high, CVT is infinitely high on CVT but the stability is poor... All the way down, only DCT double clutch transmission meets the simple operation and control Good and fuel-saving advantages!
As the name implies, the dual-clutch transmission contains two automatically controlled clutches. The two clutch discs rotate synchronously. Therefore, the power transmission interruption time during the shift process is negligible. The DCT wet double clutch on the upcoming Changan CS15 automatic transmission With a minimum shift time of 0.4 seconds, it is barely noticeable, thus ensuring the continuity and continuity of power transmission. At the same time, the power loss is also very small, and it is naturally more fuel-efficient.
Previously, the biggest market resistance of the dual clutch transmission was due to its stability. The dual clutch transmission, which was first known to most Chinese owners, belongs to the dry dual clutch. A fatal flaw in this transmission is poor heat dissipation. Excessive temperatures can burn clutch friction plates.
Isn't it that way? Of course not, "dry" is not okay, there is "wet"!
For example, the first wet DCT gearbox led by Changan Automobile's UK R&D center, the friction disc is immersed in the transmission oil, and the transmission oil can play the role of cooling and lubrication, so it can withstand greater loads. It is well avoided that the domestic urban roads are too congested to cause frequent shifting of the transmission and clutch overheating.
It's easy to use and stable! This is a wet dual clutch transmission. Of course, some people may ask, this is the transmission that super sports cars like to use, I am afraid that there is no reference value for the general public.
Who said wet dual-clutch only super sports car? The upcoming Changan CS15 automatic version, equipped with the DCT wet dual clutch, this is a small SUV Oh. Now, not only do you know how to choose a transmission, but what kind of car you choose?
