When it comes to high-performance automobiles, automatic transmissions are the popular option for easy and reliable driving. you will explore that working principles of this complex mechanism in a simple, logical way. we'll use an automatic transmission developed by Alice and Transmission for this purpose.
Automatic transmissions work based on the planetary gear set. In order to understand the process, let's take a look at the basic parts of planetary gear, he said. In an automatic transmission, planetary gear sets have one input and one output. The output rotation is drawn from the planet carrier. The two inputs are connected to the rain and some gears. What happens to the output speed when we apply different speeds to the inputs? Here, the ring gear is stationary, and rotation is given exclusively to the sun gear. The carrier will spin, and the ring gear will also rotate. The ring and sun gear rotate at the same speed. In this case, the whole mechanism moves as a single unit. The ring gear speed is increased further. Turning the sun gear in the opposite direction will result in a reverse gear.
So the operation of an automatic transmission is all about transmitting different rotational speeds into the rain. and some years. The beauty of automatic transmission is that this speed variation can be transmitted simply by engaging a few coach packs in an automatic transmission. There is no direct connection between the input and the output shafts. Rather, there is an intermediate chef between the tools. In addition, two sets are used for transmitting power. Pressing the clutch lever together will lock the hub to the case. This is the simplest form of automatic transmission. With this in mind, let's see how the first gear works. If the first clutch pack is applied, the input chef will connect to the intermediate chefs. On the other hand, if the second clutch pack is applied, the ring gear will connect to the case, which will make the range become stationary. In order to achieve the first gear, just apply both the clutch packs together. You can be sure that the input chef will turn this sun gear.
Since the ring is stationary, the output cheap will rotate at almost one third of the input speed. to achieve additional gear ratios on another planetary gear. It is clear that applying c to one will always rotate both the sun gears at the input shaft speed. If we apply to it as well, the planet's career of the second set will turn. But here's the tricky part: this planet carrier is permanently linked to the region of the first set. So when see one and see four are applied together, the ringer of the output set will turn. Thus, at the output, the situation is similar to that of the first gear. Except that here, the rainy season will rotate as well. This means that the speed of the output planet carrier will increase. This is the second gear of the transmission.
The planet's career is also fitted with a hollow shaft. The shaft can be directly connected to the input shaft with the help of a rotating clutch module. If you take a moment to observe and understand this arrangement, the rest of the process will be easy. With this set up, we can achieve a fourth gear that is direct drive. We know that in order to get a direct drive, the ring and sun gear of the output should rotate at the speed of the input shaft. If we apply, see one and c two, this is what happens.
the sun and rain gear will be directly connected to the input shaft. Simply remove the c one and apply the four here at the second set to achieve the sixth gear. input rotation is given to the career and the ringer station. This combination has a very high rotational speed for the sun. So we can achieve a high overdrive ratio at the output. A third planetary gear, they said, is required to get the remaining gerais. The sun gear of this said is always connected to the input shaft, and here again, the output of the set is connected to the input of the agency. This means that applying see three will always turn the ringer of the second set. For the remaining three georgios, see three, is always applied. For the third year, just apply and see one as well. For the fifth gear, remove one and apply the other two.
In order to go in reverse, apply the radio cloud to see five as well. Since the planets in the second set cannot revolve, they will spend action here. This will eventually lead to the reverse rotation of the sungar. Consequently, the final output will be a rotation in the opposite direction. A transmission control unit will decide when to apply the catch pack. Unlike manual transmissions, a talking and voting system is needed in the automatic transmission. When the transmission is in gear and we apply the brakes, we have to isolate the rotation of the Egypt from the transmission. With a fluid coupling, the target voter will help accomplish this. The animation will also give you a good idea of the automatic transmission.
