Buying a car or a house is a major life event. No one wants to spend hundreds of thousands or even hundreds of thousands on a faulty car. The gearbox is one of the three major parts of the car. If there is such a failure, it is terrible and annoying, so which gearbox is the most reliable?Let's start with manual transmissions.
Despite the fact that they are being phased out, the quality of manual transmissions is already very stable. As long as you choose a common car brand, there will be almost no breakdowns when using it. Compared to the shift feel and manufacturing precision, for example, Volkswagen's manual transmission is excellent in terms of shift feel and gear clarity, while the manual transmission of Japanese cars is slightly weaker.
It feels hard to use. Self-owned manual transmissions have also made great progress, such as the difficulty of shifting gears and unclear gears in previous years, which are now becoming less and less. The AT gearbox has mature technology, reasonable structure and is not easy to damage. And after years of inspection, everything that can be improved has been improved.
The input power of the AT gearbox is a hydraulic torque converter, which is a soft connection: another function of the torque converter is torque conversion, which can double the torque of the engine. The deceleration mechanism inside the gearbox is not an ordinary deceleration, but consists of multiple planetary gears. Shifting gears is even more exciting, using the clutch to shift gears. There are several sets of clutch plates in the gearbox.
Gear changes can be achieved by pressing the start-stop clutch plates in the corresponding gear. There is no effect on the gears when shifting gears. When the clutch is engaged, part of the impact is eliminated, so the impact on the gears is negligible. Wear and tear between the hardware is very low, so an AT-qualified gearbox has a long service life.
After hundreds of thousands of kilometers, the clutch plates and gaskets can still be used, and the maintenance cost is not high. The MT gearbox achieves the purpose of shifting gears by moving the gear lever, changing the gear position in the gearbox and controlling the degree of engagement of the clutch. When the clutch is depressed and the gear lever is moved.
Cars are faster and more fuel-efficient than automatic transmission cars when accelerating or overtaking. Therefore, the advantage of MT gearbox is that it is full of driving pleasure, and MT gearbox is about 10,000-20,000 yuan cheaper than automatic transmission. DCT Transmission: The most efficient transmission. Advantages: direct transmission, high transmission efficiency, fast gear shifting, great driving pleasure.
Disadvantages: poor smoothness at low speed, poor mass stability, and low maximum torque. The dual-clutch gearbox initially made a bad impression because the dual-clutch gearbox did not have a torque converter and controlled two sets of gears through two input shafts, which were engaged and disengaged for shifting operations. The structure is much simpler than that of an AT gearbox.
Therefore, it is a big test for the adjustment of car companies. Currently, many dual-clutch transmissions work just fine, such as the dual-wet clutches from Volkswagen, Hyundai, and Lynk & Co. The main factor affecting the life of the dual clutch is the adjustment of the manufacturer, and the clutch plate of the dual clutch is more susceptible to high temperatures.
So theoretically, the clutch plates of a dual clutch are more likely to be damaged. In the case of long-term traffic congestion, the service life of the dual-clutch transmission will be significantly shortened. It is not advisable to blindly follow which gearbox to follow when buying a car. You can buy it according to your car model and your own needs. AT transmissions, although relatively the most reliable, have higher fuel consumption.
Low gears are rarely equipped. The terminal model, dual-clutch wet gearbox, good performance, good shifting, fast response, fuel saving, suitable for consumers who pursue performance and family use, although the CVT can not withstand too much torque, but it is suitable for self-driving. Starting model with a small displacement. It is characterized by smoothness and fuel efficiency. Dual-clutch dry shifting is fast and fuel-efficient.
If you know its Xi before driving, it will be very reliable. The above sharing on this topic is my personal opinion and suggestion.
