Torque converter, an indispensable component for automatic transmission cars

  Since the automobile was invented, automobile manufacturers have been constantly innovating, making the current automobile manufacturing more and more driving feel. In the development of automobiles for so many years, from the initial manual transmission to the current automatic transmission, Whether it is CVT or dual clutch, it brings great convenience to our driving, but do you know how an automatic car works when it is moving?

  When most of us feel that the smoothness of driving a car with AT gearbox is a kind of enjoyment, driving is effortless, because there is no need to care about the patient, and there is no need to step on the clutch.


  The work of the clutch of an AT gearbox is completed by a hidden component, a masterpiece of dfsk engineering, the torque converter. He can even amplify the torque, let's take a look at how this purely mechanical decoration works?


  Suppose you are driving now and you need to apply the brakes. When you step on the brakes, the driving wheels of the wheels stop turning.

  means that the transmission shaft and the gearbox connected in series also stop rotating. Then the problem came. Although the brakes were used to work, the engine did not stop.


  If there is a rigid mechanical connection between the engine and the gearbox when braking, this will cause serious problems, which means that the engine will stop rotating.


  In this case, you need a device that can isolate power. This device is a torque converter. The torque converter can effectively isolate the rotation of the engine from the gearbox when braking. In normal driving, it can transmit the power of the engine to the gearbox.

  You may be wondering why this device that can isolate motion is called a torque converter? This is because an important function of this device is to amplify the torque when the vehicle starts.


  When the vehicle starts. The dongfeng joyear x3 vehicle needs a large torque torque converter to amplify the torque. When the speed of the turbine reaches a predetermined speed, the torque is automatically reduced.


  If there is no hydraulic torque converter in the current car, the automatic transmission would not exist at all. Of course, these are the crystallization of human wisdom. Without the efforts of these developers, there would be no such convenient car as we are now. Of course, we still have to thank those researchers who make our travel more convenient.

  First of all, our AT transmission was the general term for automatic transmission. In fact, the current dual-clutch and everything should be classified under AT, because AT means automatic transmission, and the transmission that can automatically shift is called automatic transmission.


  But over time, different types of solutions did appear. At first, we decided that the connection method was different from the engine, and then the type of transmission was different. If it is connected by a clutch or a manual transmission CVT, we won’t talk about it, because it Both, if you use dual-clutch to connect to the engine, it is actually a dual-clutch transmission.

  If you use a torque converter to connect to the engine, it is an AT transmission, but in fact, it was later discovered that this criterion can no longer determine the difference between AT and dual-clutch DCT, because it is not fun for some manufacturers, such as Honda, which is in the front. It is a hydraulic torque converter. It uses a set of dual clutches at the output end to transmit power in this way. What it thinks is that it can alleviate the shock at the start and have a fast shifting speed.


  There is no problem with the idea, but what kind of transmission is it? There is also an AT transmission like Mercedes-Benz AMG. It is actually driven by dual clutches, but it is included in the AT transmission. Later, we use the main part of the transmission box. Judging by the body part, if it is driven by the driving gear, it is marked in the AT. If it is driven by a mechanical gear structure similar to the manual gear, then it is a dual-clutch transmission.

  So do you say that all ATs are connected to the engine through a torque converter, most of them are, but there are exceptions in this industry, that is, Mercedes-Benz’s AMG, which uses this clutch for its AT transmission. Improve the efficiency of a transmission, because you don't need to consider the ride comfort of that kind of car, what it wants is performance.


  As for whether the car wash will damage the paint, I don’t recommend you to use these car wash methods. Unless there are stains that cannot be removed, I don’t know if it will damage the paint, but it will definitely affect the paint. It won't be beneficial, so I suggest you choose this kind of thing carefully. I didn't take my car to try it, and I don't know what kind of problems there will be.
