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.
