The current automatic transmission is the most elaborated mechanical component in today’s automobile. It includes Mechanical systems, Electrical systems, Computer controls, and Hydraulic systems. All the above-mentioned systems are working in perfect harmony which goes virtually unnoticed until there is some difficulty. It is a device that sends the energy from the engine to the drive wheels and is connected to the back of the engine. While starting the engine or climbing a hill, the transmission system provides high torque. Automatic Transmissions are of two types:
Rear
wheel drive: In this, the transmission is usually attached to the back of the
engine. Power flowing from the engine in this system is straightforward. It
flows through the torque converter, the transmission, and the drive shaft and
then reaches the final drive in the end where it is split. It is then sent to the
two rear wheels. An example of a rear wheel is Alpha Alfeto in the early
70s.
Front-wheel
drive: A transaxle is formed when the transmission is combined with the final
drive, on a front-wheel drive. It is a set-up in the transmission gearbox,
clutch, and final drive, all fixed together in a single unit. The front wheels
of the vehicle are driven in those front-wheel drive layouts. It is the most
popular layout used in cars today. Its compact packaging has what made it that
popular. The transaxle is directly connected to the front axles and these front
axles provide power to the front wheels.
Some of
the components of Automatic
Transmissions are Planetary gear sets, a Hydraulic
system such as an oil pump, valve body, clutches and bands, Seals and Gaskets,
Torque converter, Governor, and Computer controls.
