Compared to traditional fuel vehicle gears, new energy vehicle gears have the following main characteristics:

1. High precision requirements: New energy vehicles usually use high torque motors, which require higher precision for gears to ensure the accuracy of gear meshing and transmission efficiency, and reduce energy loss.

2. High strength and wear resistance: Due to the large output torque of the motor in new energy vehicles, gears need to withstand higher loads. Therefore, gear materials need to have higher strength and wear resistance to cope with long-term use and heavy loads.

3. Low noise and low vibration: Electric vehicles have strict control over noise and vibration, and gears need to maintain low noise and low vibration during operation to improve ride comfort

4. Lightweight: New energy vehicles attach great importance to weight control because reducing weight can directly improve the vehicle's endurance. Therefore, lightweight materials and technologies will be used in the design of gears.

5. High temperature resistance: The motors and controllers of new energy vehicles generate high temperatures during operation, and the gears need to maintain stable performance in high-temperature environments.

6. Long lifespan: New energy vehicle gears require a longer service life to reduce maintenance costs and replacement frequency.

7. Environmentally friendly materials: In order to meet the environmental characteristics of new energy vehicles, gears will be manufactured using environmentally friendly materials and processes as much as possible to reduce their impact on the environment.

8. High efficiency transmission: The gear design of new energy vehicles requires higher transmission efficiency to improve energy utilization and vehicle performance.

9. Specific design requirements: The gear design of new energy vehicles may need to adapt to specific modes, such as single speed transmission or multiple speed ratio transmission, to meet different driving needs.

10. Compatibility with the motor: The gear system needs to match the characteristics of the motor to ensure the efficiency and performance of the entire electric drive system.

These characteristics make new energy vehicle gears have special requirements in material selection, design, manufacturing, and testing to meet the high performance, high efficiency, and environmental protection needs of new energy vehicles.
