Automotive gears are key components in the automotive transmission system, responsible for transmitting power and changing speed and torque. The following is a detailed introduction to the classification of automotive gears:

Classified by function:

Transmission gears: used to transmit power, such as gearbox gears, differential gears, etc.

Steering gear: used to change the direction of power, such as steering gear.

Reduction gear: Used to reduce speed and increase torque, such as the main reducer gear.

Classified by shape:

Spur gear: a gear whose tooth surface is parallel to the axis, with smooth transmission but high noise.

Helical gear: a gear whose tooth surface forms a certain angle with the axis, with smooth transmission, low noise, but high axial force.

Cone gear: The tooth surface is conical and used to transmit power between intersecting axes, such as differential gears.

Worm gear: Used to transmit power between vertically staggered axes, with a high transmission ratio but low efficiency.

Classified by material:

Steel gears: high strength, good wear resistance, widely used in various transmission systems.

Cast iron gears: Low cost, suitable for low-speed, low load transmission.

Plastic gears: lightweight, low noise, suitable for light load transmission.

As the core component of the automotive transmission system, the performance of automotive gears directly affects the driving experience and safety of the car.
