What are the classification and advantages and disadvantages of transmissions

Transmissions are categorized into manual transmissions, normal automatic transmissions, CVTs, dual clutch transmissions and AMTs. Various transmissions have their own advantages and disadvantages. The one that suits you is the best.

Advantages of manual transmission:Simple structure, reliable performance, low manufacturing and maintenance costs, high transmission efficiency. Because it is purely mechanical control, the gearshift response is fast, and it can express the driver's wishes more directly, so it is more enjoyable to drive. Disadvantages:But compared with automatic transmission, it is more troublesome to operate. Advantages of normal automatic transmission:The technology is mature and stable, and the ride comfort is also good. There is no need to shift gears when driving in general. Widely used in high-end models of major brands. Disadvantages:Loss of transmission efficiency, so the fuel consumption is high, the internal structure is precise and complex, and the maintenance cost is high.Advantages of CVT:Smooth when shifting gears, no jerky, and fuel saving. Disadvantages:Because it is driven by steel belt friction, it is easy to slip when accelerating sharply, the transmission power is limited, and it can't be used in high-power vehicles above 3 liters. Advantages of dual clutch transmission:Dual clutch transmission combines the advantages of manual transmission and automatic transmission. Two clutches are used instead of a torque converter. The two clutches work alternately with each other to achieve the effect of backlash-free gear shifting. Disadvantages:Since no torque converter is used, it is impossible to realize the "semi-linkage" action of manual transmission, and for the engine with smaller displacement, the characteristic of insufficient torque at low speed will be fully exposed. amt transmission advantages:Amt transmission retains the advantages of high transmission efficiency, compact mechanism, reliable operation, easy manufacturing, etc. inherent in traditional MT gear transmission. It has the advantages of high transmission efficiency, compact mechanism, reliable operation, easy manufacturing and so on. Compared with AT, it not only responds faster, but also increases power by more than 7% and saves fuel by 10 ~ 15%. Disadvantages: when shifting, the single clutch gear is connected to the platform, the power will stop briefly when the clutch is separated, the ride comfort is not as good as ordinary AT hydraulic joints, limiting its application in high-end luxury cars.
