The gear of the gearbox is 124R35. What gearbox is it?

Automobile gearboxes are divided into manual and automatic. Manual gearbox is mainly composed of gears and shafts, which produce variable speed and torque through different gear combinations. Automatic gearbox at is composed of hydraulic torque converter, planetary gear and hydraulic control system, which realizes variable speed and torque by means of hydraulic transmission and gear combination.

The economy and practicality of a car are not entirely determined by the number of gears. Because if you want to reach the highest grade, the premise is to have enough acceleration time and driving speed, because the greater the speed ratio, the higher the corresponding maintenance speed, and only at this time can you show the economic advantages of 8 speed ratio and 7 speed.

In fact, this also extends a problem, that is, the more gears in the gearbox are related to the power output of the engine.

If you use a 0.8-liter three-cylinder machine with a 6-speed automatic transmission, it is definitely overqualified, so the speed ratio of the 4-speed automatic transmission is more suitable for its power. Another reason is that most automatic gearboxes are equipped with manual shift function, and the f 1 car has only 7 gears at most. If there are more gears, Schumacher will be in a hurry. Judging from the structure of the 8-speed automatic gearbox, its complexity is no less than a finely crafted handicraft, which can only be accommodated by luxury cars with huge volume, high cost and wide body.
