What is the difference between AMT and manual-automatic transmission?
1 Answers
Transmission is one of the important drivetrain components of a car, and transmission performance is also a key parameter determining vehicle performance. Transmissions are mainly divided into manual transmissions and automatic transmissions. Among them, both AT and AMT belong to automatic transmissions. The specific differences between the two are as follows: AT Transmission: The AT transmission consists of a valve body, oil pump, clutch, brake, one-way clutch, diaphragm spring, snap ring, steel plates, friction plates, large sun gear, small sun gear, planetary carrier, and ring gear. The AT transmission has a complex and precise structure, and in actual vehicle installation, it needs to be connected to a torque converter. AT - Automatic Transmission, mature technology, relatively higher fuel consumption. AMT Transmission: The AMT transmission is essentially a manual transmission with automatic clutch and gear-shifting control functions. Its structure is fundamentally the same as that of a traditional parallel-shaft manual transmission. AMT transmissions generally have relatively larger shift shocks (though advancements in electronic control technology have made shifting actions and timing more precise, reducing the shocks). They are simple in structure, highly reliable, and easy to maintain. Since they are essentially manual transmissions with added automatic clutch and shifting mechanisms, they have more gear ratios, making them more adaptable to various complex operating conditions. Ordinary AMT transmissions cannot amplify input torque because they lack a torque converter, except for some heavy-duty transport vehicles that use AMT transmissions equipped with torque converters to handle their specific operating conditions.
