1.1 Shift gearbox
Classification usually gearbox as follows: Manual transmission
The general automatic gearbox / common automatic transmission with tiptronic
CVT stepless gearbox with gear box of the /CVT Dual clutch gearbox Sequential gearbox (1) manual gearbox
Manual transmission, also known as manual gear, English name is manual transmission, referred to as MT, which push the shift lever to change gears meshing position inside the transmission, changing the transmission ratio, so as to achieve the purpose of speed. Step on the clutch, can move the shift lever.
The working principle of a manual gearbox
The manual gear box is composed of different gear ratio of the gear group, its basic principle is through the gear group work in different, to realize the transformation of gear ratio. As the key link for power distribution, transmission must have the power input shaft and the output shaft of the big two, together constitute the transmission gear, is a manual transmission is the most basic component. The power input is connected with the clutch shaft clutch

transmission, from the power to directly through the input shaft to the group, the gear set is composed of different diameter gear, gear power transmission effect of different proportion reached is completely different, the usual shift driving also refers to change gear ratio.
Next, let us through a simple model to tell you, the principle of manual gearbox shift. Below is a simple structural model of 3 axis 2 speed gearbox.

The input shaft (green) is also called the first shaft, connected by a clutch and engine, shaft and the gear is a hard connected components. Red is called the intermediate gear shaft. Enter the two gear shaft and intermediate shaft is in constant mesh state, so when the input shaft rotates will drive shaft rotation. Yellow is the output shaft, it is also called the second shafts and connected to the drive shaft (only for rear wheel drive, the precursor is generally two), and then through the differential drive vehicles.
When the wheel rotates the same with spline shaft to rotate together, at this time, blue gear shaft can occur on the spline shaft relative free rotation. Therefore, the engine stops, and the wheel is rotated, the blue gear and shaft in the stationary state, and the spline shaft with wheels. The principle and the rear
