Automotive gear is a vital part of the automotive transmission system, the main role is to transfer power between the engine and the wheels, to ensure that the vehicle can travel at the appropriate speed and torque. Here are some detailed descriptions of car gears:

Basic functions: The car gear transmits the power generated by the engine to the wheel through the way of meshing to achieve the vehicle's acceleration, deceleration, steering and other functions.

Type:

Spur gear: used to transmit rotating motion between two axes.

Helical gear: Compared with spur gear, helical gear tooth surface is at a certain Angle, can withstand greater load, and more stable transmission.

Bevel gear: Used to transmit the rotating motion between the two axes at a certain Angle, commonly seen in the rear axle drive of automobiles.

Planetary gears: Used to achieve complex power distribution, such as planetary gear sets in automatic transmissions.

Application: Automotive gears are widely used in manual transmission, automatic transmission, differential, drive axle and other important parts.

In short, the automotive gear as one of the core components of the automobile, its technological progress and innovation is of great significance to the development of the entire automotive industry.
