Automatic Transmissions: How it works?

If you used to drive a car, you might be surely knowing that there are two types of transmissions in a vehicle i.e. manual transmission and automatic transmission.

Transmissions gears and shafts doesn’t have any clutch pedal in the car. In an automatic transmission, there is no gear shift. The car runs automatically once you put the transmission of the car into the drive mode.

Automatic transmissions do its work by the torque converter present in it. A torque converter is the source which takes the place of clutch in the automatic transmission. It has four components by which it performs its actions i.e. the turbine, the impeller, the lock-up clutch, and the stator.

In this, the input shaft is connected to the turbine and the impeller to the engine which drives the turbine by various forces. And the impeller rotates the turbine which sends the torque to the transmission. The work of the stator is to be between the turbine and the impeller. It helps in increasing the output of the torque and redirecting the fluid which returns from turbine to the impeller. The work of the lock-up clutch is to lock the turbine so that it can be mechanically connected to the impeller.

Summary

As it is known that Transmission,Gears and Shafts are divided into many parts and types and here is described about the working of the automatic transmissions. Now it could be said that both the transmissions do the same work but in very different ways. The work process of automatic transmissions is totally amazing as it changes the gears of the car automatically
