What are the types of transmissions?
1 Answers
Transmissions are mainly divided into the following types: 1. AT Transmission: Officially known as Hydraulic Automatic Transmission, this is the most commonly encountered automatic transmission. The advantages of AT transmissions are obvious, offering more direct power, but the drawbacks are also prominent, including noticeable jerking during acceleration and relatively higher fuel consumption. 2. CVT Transmission: Officially named Continuously Variable Transmission, it is primarily represented by Japanese cars, with models from Honda and Nissan mostly using CVT transmissions. The characteristics of CVT transmissions are quite distinct. Since the gear ratio is not a series of discrete points but a continuous range of values, it provides excellent smoothness and outstanding fuel economy. However, the downside is also relatively obvious, lacking a burst point in instantaneous power output. 3. MT Transmission: Short for Manual Transmission, AMT (Automated Manual Transmission) is a hybrid between MT and AT transmissions. Its advantage lies in lower production costs and more convenient operation compared to manual transmissions. However, the disadvantages of AMT transmissions are more pronounced; improper operation can easily lead to strong jerking, significantly affecting comfort. 4. Dual-Clutch Transmission: Abbreviated as DCT, it employs two sets of clutches that alternately work to achieve seamless gear shifting. It is further divided into dry and wet dual-clutch transmissions. Dual-clutch transmissions offer fast shifting speeds and minimal power loss during gear changes.
