Preventing damage to automotive gears requires a comprehensive consideration of the daily use and maintenance of the vehicle. Here are some key measures to prevent damage to car gears:

1. Regularly replace lubricating oil:

Regularly replace the lubricating oil of the gearbox and differential according to the manufacturer's recommendations.

Use recommended types of lubricants to ensure proper lubrication and protection of gears.

2. Avoid excessive load:

Avoid driving for long periods of time under heavy loads or extreme conditions, such as climbing slopes with a full load or dragging heavy objects, as this will increase the load on the gears.

3. Smooth driving:

Avoid sudden acceleration, deceleration, and turning, as these operations can cause additional pressure on the gears.

4. Correct gear shifting:

Shift gears at the appropriate speed and RPM to avoid excessive engine RPM during gear shifting.

5. Avoid coasting in neutral:

When driving downhill or for a long time, avoid coasting in neutral for a long time, as this may cause excessive wear on the transmission gears.

6. Regular inspection:

Regularly inspect the gearbox and differential for leaks, abnormal noises, or other abnormal conditions.

Check the gear oil level and quality to ensure that the oil is clean and at the appropriate level.

7. Keep the cooling system working properly:

Ensure that the cooling system (such as the gearbox cooler) is functioning properly to prevent gear oil from overheating.

8. Avoid prolonged high-speed driving:

Avoid driving at high speeds for long periods of time, especially in low gears, as this can increase gear wear.

9. Use high-quality fuels and lubricants:

Use high-quality fuel and lubricants to reduce engine and gearbox wear.

10. Avoid sudden acceleration or deceleration when dragging heavy objects:

When dragging heavy objects, avoid sudden acceleration or deceleration, as this will increase the load on the differential gear.

11. Pay attention to vehicle load:

Avoid exceeding the rated load of the vehicle, as heavy loads can increase gear wear.

12. Avoid driving for extended periods of time in extreme temperatures:

Avoid driving for long periods of time in extreme high or low temperature environments, as extreme temperatures can affect the effectiveness of lubricating oil.

By taking these preventive measures, the risk of damage to automotive gears can be significantly reduced, the service life of the gear system can be extended, and the reliability and performance of the vehicle can be ensured.
