What Are the Differences Between Transmission Types?

[LaMiranda]

Here is the classification of transmissions along with their descriptions: Manual Transmission (MT), Automated Manual Transmission (AMT), Dual-Clutch Transmission (DCT), Automatic Transmission (AT), and Continuously Variable Transmission (CVT). Differences explained: 1. Manual Transmission (MT): Composed of gears and a mechanical clutch for each gear, it has a simple structure, high transmission efficiency, and is highly reliable. However, it requires full manual operation, including clutch engagement, which can be a bit cumbersome. But it also offers driving pleasure and helps improve driving skills. 2. Automated Manual Transmission (AMT): Similar in structure to a manual transmission, but the entire gear-shifting process is completed by electronic controls, eliminating the need for manual operation. However, due to insufficient automation in the electronic control system, gear shifts can feel noticeably jerky. Often used as a low-cost automatic transmission solution for economy cars; its simple structure and high shift efficiency also make it popular in racing. 3. Dual-Clutch Transmission (DCT): Similar in structure to a manual transmission, it consists of two sets of clutches. When driving in one gear, the next gear is already engaged and ready to work, resulting in very fast gear shifts, though smoothness at low speeds is slightly compromised. Initially used in sports cars, it is now widely adopted in various vehicle types. 4. Automatic Transmission (AT): Composed of components like a torque converter, its structure is relatively complex. Some power is lost during gear shifts, leading to slightly lower transmission efficiency. However, it shifts smoothly and is mature and reliable in technology, making it the choice for most automatic vehicles. 5. Continuously Variable Transmission (CVT): Primarily consists of two cone-shaped pulleys and a steel belt, allowing for continuous adjustment of the gear ratio. In theory, it is the smoothest and most economical among all transmission types. However, due to its structural limitations, it cannot handle high torque during aggressive acceleration. It is commonly used in vehicles prioritizing economy and comfort.
