Automatic transmissions suppliers in Delhi NCR

We use automatic transmissions developed by AVTEC Transmission for this purpose. Automatic transmissions work based on the planetary gear set. In order to understand this process, let take a look at the basic parts of planetary gear sets.

Now let see 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. This will cause the carrier to spin as you can see here. The ring gear is also rotating. The ring and sun gears 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 reverse gear. So the operation of automatic transmission is all about transmitting different rotation speeds into the ring and sun gears. The beauty of automatic transmission is that this speed variation can be transmitted simply by engaging a few clutch packs. In the coming sessions. In an automatic transmission, there is no direct connection between the input and the output shafts, rather there is an intermediate shaft between the two. 

In addition to clutch packs are used for transmitting power. Pressing the clutch packs together will lock the hub to the case. This is the simplest form of automatic transmission. With this in mind, let see how 1st gear works. If 1st clutch pack is applied the input shaft will connect to the intermediate shaft. On the other hand, if the 2nd clutch pack is applied, the ring gear will connect to the case which will make the gear become stationary. In order to achieve 1st gear just apply both the clutch packs together. You can note that the input shaft will turn the sun gear. Since the ring gear is stationary the output shaft will rotate as shown with almost one-third of the input speed.
