What is the Function of an Automatic Transmission?
2 Answers
An automatic transmission is a gear-shifting device that can automatically change gears based on the vehicle's speed and engine RPM, with its core function being to achieve automatic gear shifting. Below is an introduction to automatic transmissions: 1. Types: There are three common types of automatic transmissions in vehicles, namely AT transmissions, dual-clutch transmissions, and CVT transmissions. Dual-clutch transmissions are a product developed based on manual transmissions. 2. AT Transmission: AT transmissions, also known as torque converter transmissions, are connected to the engine via a torque converter. 3. CVT Transmission: CVT transmissions are a type of automatic transmission with a relatively simple internal structure, consisting of only two cone pulleys and a steel belt inside.
Having driven for over 20 years, automatic transmissions are simply a lifesaver in traffic jams. It's like having a smart assistant that shifts gears automatically based on speed and throttle input, completely eliminating the need to worry about clutch pedals or gear changes. Especially on mountain roads or during rush hour, not having to constantly operate the right foot significantly reduces fatigue. More importantly, it keeps the engine operating within the optimal RPM range, avoiding the stalling issues that new drivers often encounter with improper gear selection. Nowadays even pickup trucks and off-road vehicles use automatic transmissions—their reliability is proven, though regular fluid changes are essential to prevent jerky shifting. Honestly, after getting used to the convenience of automatics, there's really no going back to manual transmissions.
