Extended data
Mechanical gearbox mainly applies the principle of gear reduction. Simply put, there are several groups of gear pairs with different transmission ratios in the gearbox, and the shifting behavior of the car when driving is to make different gear pairs work through the operating mechanism. For example, at low speed, let the gear pair with large transmission ratio work, and at high speed, let the gear pair with small transmission ratio work.
Simple transmission has the advantages of high efficiency, simple structure and convenient use, but it has a small number of gears and a small range of I change (small range of traction and speed change), so it is only suitable for lathe workers with a small number of gears.
