2、附 錄 A 外文文獻Manual transmissionManual transmission is the most basic of transmission of a type, its effect is changing, and provide the transmission reverse and neutral. Usually, the pilot on the clutch pedal through manipulation and in any HuanDangGan can choose between gear. There are a few manual transmission, such as motorcycles, cars, some transmission shift transmission allows only sequence, the transmission is called sequence shift transmission. In recent years, along with the electro。

3、附錄 A 英文文獻Transmission descriptionTransmission gearboxs function the engines output rotational speed is high, the maximum work rate and the maximum torque appears in certain rotational speed area. In order to display engines optimum performance, must have a set of variable speed gear, is coordinated the engine the rotational speed and wheels actual moving velocity. The transmission gearbox may in the automobile travel process, has the different gear ratio between the engine an。

4、1Transmission designAs we all know,automobile engine to a certain speed can be achieved under the best conditions, when compared issued by the power, fuel economy is relatively good. Therefore, we hope that the engine is always in the best of conditions to work under. However, the use of motor vehicles need to have different speeds, thus creating a conflict. Transmission through this conflict to resolve.Automotive Transmission role sum up in one sentence, called variable speed twisting, twisting。

5、附 錄附錄 A 英文文獻Transmission descriptionTransmission gearboxs function the engines output rotational speed is high, the maximum work rate and the maximum torque appears in certain rotational speed area. In order to display engines optimum performance, must have a set of variable speed gear, is coordinated the engine the rotational speed and wheels actual moving velocity. The transmission gearbox may in the automobile travel process, has the different gear ratio between the engin。

6、附 錄 AThe output of the engine speed is very high, the maximum power and the maximum torque in a certain speed area appears. In order to bring into full play the best performance engine, it must have a variable speed device, to coordinate the speed of the engine and the actual speed. Transmission can be in the course of driving in the car, and the engine between different ratios of produce, through the shift can make the engine to the best in the dynamic properties of state. The three main tra。

7、附 錄How Manual Transmissions WorkIf you drive a stick-shift car, then you may have several questions floating in your head.How does the funny H pattern that I am moving this shift knob through have any relation to the gears inside the transmission? What is moving inside the transmission when I move the shifter? When I mess up and hear that horrible grinding sound, what is actually grinding? What would happen if I were to accidentally shift into reverse while I am speeding down the fr。

15、附 錄Market Analysis and Forecast of Light Vehicle Transmission1 Global transmission market statusThe current global vehicle production increases at an average annual rate of 3.5% per year and is expected to at least 89 million at 2015. With the increase in light vehicle production, manual transmission and planetary gear automatic transmission is also expected to yield increases, but they will be occupied a part of the CVT market share by the AMT. Compared with planetary gear transmission, AMT a。
