1. The so-called automatic gearbox (AT) is different from the manual gearbox (MT). It eliminates the manual operation of the clutch and realizes automation. It is a design that reduces the driver's burden and gives priority to safe driving. The vehicle will automatically select the appropriate gear according to the driving speed and traffic conditions. ?
2. In the current automobile market, the price difference between manual and automatic gears of various models is generally between 1 1,000-20,000 yuan. It is understood that the transmission mechanism of manual gear is relatively simple in structure, convenient to manufacture and maintain and low in cost; The structure of automatic transmission mechanism is relatively complex, with high manufacturing cost, difficult maintenance and high cost. However, in actual use, because there are fewer transmission mechanisms for manual operation of automatic transmission, the probability of failure is also small. In general, the automatic transmission only needs to be replaced regularly. Manual gear
In addition to regular replacement, the clutch plate should be replaced according to wear and tear. Therefore, for a long time, the maintenance frequency and cost of manual gears are not low.
3. When not in use, because the power of manual transmission is directly transmitted, the efficiency is slightly higher than that of automatic transmission, and the same speed is slightly lower, saving very little oil. The main fuel-saving method is that when the manual gear slides, the engine only runs; The automatic gear can't be used for driving, and there are more gears, which leads to the difference in fuel consumption.
