manual transmission, also called manual transmission, the English called manual transmission, referred to as MT, i.e. the toggle lever to change the gear engagement position within the transmission, change the transmission ratio by hand, to achieve the purpose of the transmission. When the clutch depressed, only have to move the shift lever dial.
1. noun manual gearbox interpretation
manual transmission, also known as manual transmission, the English called manual transmission, referred to as MT, namely hand toggle lever to change gears in the transmission engagement position, change the transmission ratio to achieve the purpose of the transmission. When the clutch depressed, only have to move the shift lever dial.
2. Advantages and disadvantages of the manual transmission
apparent advantages of simple structure, reliable, and low manufacturing and maintenance costs, and high transmission efficiency (in theory, would be more fuel-efficient), In addition, since pure mechanical control, quick shift reaction, and can be more direct expression of the will of the driver, and therefore richer driving pleasure, these are the advantages of a manual gearbox. But compared to the automatic transmission, it is cumbersome to operate, and frustrated at a distinct disadvantage when the range switching is irreparable.
3. The operating principle of a manual transmission
is a manual transmission gear sets have different gear ratio configuration, the basic principle is that it works through different switching gear sets to achieve the teeth ratio of transformation. As a key link power distribution, power transmission must have both the input shaft and the output shaft large, constituting together with the gear transmission, a manual transmission is the most basic components. Power input shaft and the clutch is connected, the power transmission from the clutch is transmitted directly through the input shaft to the gear set, the gear train is composed of different diameter gears of different gear ratio achieved by the power transmission effect is completely different, normal driving also refers to the shift change gear ratio.

4. The action of the manual transmission
Physical characteristics of the engine determines the presence of transmission. First, any engine has a peak speed; second, engine maximum power and maximum torque occurs at a certain speed range. For example, the engine maximum power at 5500 rpm appear. Transmission can produce different gear ratio between the engine and the wheels in an automobile traveling, the shift may be such that the engine operate at its optimum power performance state. Ideally, the transmission gear ratio should be flexible. The continuously variable transmission (CVT) to have this characteristic, can play a better dynamic performance of the engine.
