#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.
