Automatic transmission is a type of motor vehicle
transmission that automatically changes the gear ratios as the vehicle start
moving, thus freeing the driver from such hardships. The most common type found
in automobiles is hydraulic automatic transmission. But have you ever think
that what makes this automatic transmission possible? Such type of transmission
consists of several transmission components and systems that are particularly designed to work together in a
symphony of electrical, hydraulic and mechanical energy. Let’s get to know
about these components that make this transmission actually possible.
The hydraulic system
This basically controls the clutches and bands so as to
control the planetary gear sets. For the proper functioning, it uses special
transmission fluid which is sent under pressure by the oil pump.
Planetary Gear Sets
Planetary gear sets is one of the important transmission components that provides
the several forward and reverse gear ratios.
Seals and Gaskets
This component is used to prevent oil leaking by keeping it
at the place where it is supposed to be.
The Torque
Another important component that makes the automatic
transmission components possible is the torque converter that acts like a clutch and stop
the vehicle while the engine is still running.
The Governor and the
modulator
These components are used in the non – computerized
transmission and usually provide the inputs that instructs the transmission
when to shift.
The Computer Controls
These are related to the computerized transmissions components and use
the sensor on engine to detect the things such as throttle position, vehicle
speed, engine speed, engine load, switch position, stop light etc.
