Differential bevel gears (also known as bevel gears) are key components inside the differential, and they play a vital role in the vehicle's transmission system. The differential is located on the drive shaft, and its main function is to allow the left and right wheels to rotate at different speeds when cornering, thereby ensuring that the vehicle passes the curve smoothly.

The specific applications and functions of differential bevel gears are as follows:

• Power distribution: The differential bevel gear distributes the power transmitted from the engine to the drive shaft equally to the left and right wheels. When driving in a straight line, both wheels rotate at the same speed; when turning, the inner and outer wheels are allowed to rotate at different speeds to accommodate the difference in turning radius.
• Changing transmission direction: The design of the differential bevel gears allows them to change the transmission direction. Usually, the main bevel gear (connected to the drive shaft) and the driven bevel gear (connected to the wheels) of the differential are perpendicular to each other, so that the rotational torque can be transmitted to the wheels while changing the direction of the force.
• Wear-resistant and impact-resistant: Differential bevel gears need to withstand large loads and impacts, so they are usually made of wear-resistant materials, such as alloy steel, and undergo special heat treatment to improve their durability.
• Precision manufacturing: The differential bevel gears are manufactured with very high precision to ensure correct meshing between gears and minimal transmission errors. This helps reduce noise and improve transmission efficiency.
• Oil lubrication: The differential bevel gear works in a differential oil bath. The lubricating oil not only lubricates the gears, but also cools the gears and cleans the metal chips produced by wear.

The design and manufacture of differential bevel gears is critical to a vehicle's performance and reliability. Their failure or wear may result in unstable vehicle driving, increased transmission system noise, or even damage to other transmission components. Therefore, regular inspection and replacement of differential oil is an important part of car maintenance and helps to extend the service life of differential and bevel gears.
