What does AT mean in cars?
1 Answers
AT in cars refers to the hydraulic automatic transmission, which achieves automatic gear shifting through the combination of hydraulic transmission and planetary gears. The automatic transmission is a gear-shifting device that automatically changes gears based on the vehicle's speed and engine RPM, as opposed to manual transmissions. There are four common types of automatic transmissions in cars, categorized by their working principles: hydraulic automatic transmission (AT), continuously variable transmission (CVT), automated manual transmission (AMT), and dual-clutch transmission (DCT). The hydraulic automatic transmission eliminates the complex gear-shifting and frequent clutch pedal operations of manual transmissions, making driving simpler and more effortless.
