How does an AMT automatic transmission work?
3 Answers
AMT automatic transmission works as follows: When the vehicle starts or shifts gears, the clutch is engaged and disengaged by a hydraulic pump, and gear changes are also operated by a hydraulic structure. Simply pushing or pulling the gear lever completes upshifting or downshifting. In automatic mode, the transmission control computer will switch gears automatically based on data such as vehicle speed and engine load. Information about the transmission is as follows: 1. The transmission, also known as a gearbox, is an automotive component used to alter the speed and torque from the engine and can fix or change the gear ratio between the output and input shafts. 2. The transmission consists of a gear-shifting mechanism and a control mechanism, with some vehicles also having a power output mechanism. It can be categorized into stepped, continuously variable, and integrated transmissions, featuring functions such as enabling reverse driving, interrupting power transmission, and changing gear ratios.
The working principle of AMT automated manual transmission is actually quite simple. For an experienced driver like me who has been driving for decades, it's like a manual gearbox that takes care of the clutch for you. The computer system uses sensors to monitor vehicle speed and throttle position, automatically controlling the clutch and gearshift actions to select the appropriate gear based on road conditions. It eliminates the hassle of manual shifting during driving, making it particularly suitable for urban traffic jams or novice drivers. However, there might be some jerking sensation during gear changes since it's essentially still based on manual transmission architecture. I think its biggest advantage is lower cost - it's cheaper than full automatic transmissions and easier to maintain, though not as smooth in terms of comfort. Some older models equipped with this system tend to develop clutch wear issues, requiring regular fluid checks. If you prefer practical and economical vehicles, this type of transmission is worth trying.
The working mechanism of AMT transmissions excites car enthusiasts like me! At its core, it automates manual transmissions: the electronic control unit collects data on engine speed and vehicle speed, calculates the optimal shift timing, then drives hydraulic pumps or motors to operate the clutch and gear lever. During gear shifts, power is briefly interrupted, which may cause noticeable jerks, but it retains the efficiency of manual transmissions, making it more fuel-efficient than traditional automatics. I love its simple structure and lightweight design, ideal for compact cars or sports cars; the downside is it's not as smooth as CVTs, and may produce more noise at high speeds. The technology is still evolving, with smart algorithms and hybrid motors now being used to mitigate issues. If you choose this type of vehicle, pay attention to driving habits to avoid overly aggressive acceleration.
