Automatic transmissions have attracted most drivers around the world. Convenient, Comfort, hassle-free operations have moved up the use of automatic transmission.
Automatic transmissions are quicker gear shifters than manual, control module and sensors decide the optimum points of upshifts and downshift, proper gear selection is necessary for maximum fuel savings. Automatic transmissions have many variations that are used in all types of vehicles. Let’s take a look at each kind and highlight their characteristics and learn about their applications.
1.Torque Converter (AT)
2.Automated- Manual Transmission (AMT)
3.Continuously Variable Transmission (CVT)
4. Dual-Clutch Transmission (DCT)
5.Direct Shift Gearbox (DSG)
1.TORQUE CONVERTER (AT)
This is widely known as torque converter automatic transmission this found in almost every car. This transmission uses hydraulic fluid coupling or torque converter to change the gear instead of a clutch. ECU is connected to this mechanism to allow smooth and proper engine control of the vehicle.
AUTOMATED- MANUAL TRANSMISSION (AMT)
This type of transmission is not like other automatic transmissions, it uses regular (manual gearbox) clutch and gear configuration, but uses sensors, actuators, processors, and pneumatics to replicate manual gear use. Automated-manual transmission is known for jerky performance at low speeds and hard accelerations, but give high fuel efficiency (mileage) over a long distance.
CONTINUOUSLY VARIABLE TRANSMISSION (CVT)
The continuously variable transmission uses belts or pulleys instead of traditional steel gears and it allows for seamless gear shifting with various ratios dependent on engine speed or RPM. This is typically higher than the RPM that achieves peak efficiency. This allows for maximum efficiency and continuous acceleration, which is good for fuel economy
DUAL-CLUTCH TRANSMISSION (DCT)
