The gears of new energy vehicles play a crucial role in the transmission system of vehicles, and their core functions are mainly reflected in the following aspects:
1、 Power transmission
1. Motor power output:
The gears of new energy vehicles efficiently transmit the power generated by the motor to the driving wheels, enabling the vehicle to travel normally. The high speed and low torque output by the motor are transmitted and varied through the gear system, and converted into low speed and high torque suitable for wheel drive.
2. Power distribution:
In hybrid vehicles, the gear system is also responsible for the rational allocation of power output between the electric motor and the internal combustion engine, ensuring optimal power combinations under different operating conditions.
2、 Variable speed adjustment
1. Deceleration and torque increase:
By the deceleration effect of gears, the high speed of the motor is reduced while increasing the output torque, allowing the vehicle to obtain sufficient driving force under various driving conditions.
2. Transmission function:
The transmission gears of new energy vehicles can achieve variable speed function by changing the meshing relationship of gears under different driving speeds and load conditions, improving driving flexibility and adaptability.
3、 Improve transmission efficiency
1. Reduce energy loss:
High precision gear design and manufacturing make gear meshing tighter, reduce friction losses during transmission, and improve energy transfer efficiency.
2. Optimize the transmission ratio:
By optimizing the transmission ratio of the gears, the motor can operate within an efficient working range, further improving the energy efficiency performance of the entire vehicle.
4、 Reduce noise and vibration
1. Precision machining:
The precision machining and surface treatment of gears reduce noise and vibration during meshing, improving driving comfort and quietness.
2. Noise reduction design:
The special tooth design and meshing method further reduce the noise of the transmission system, making the driving experience of new energy vehicles smoother and quieter.
5、 Ensure driving stability
1. Uniform power output:
The gear system ensures even driving force for the wheels and improves the stability of the vehicle through smooth power transmission.
2. Adapt to various working conditions:
Under different driving conditions, the gear system can be flexibly adjusted to maintain stable power output and driving status of the vehicle.
6、 Extend service life
1. Wear resistant materials:
Adopting high wear-resistant materials and advanced surface treatment technology to enhance the wear resistance of gears and extend their service life.
2. Structural optimization:
By optimizing the structural design of gears, their fatigue resistance is improved to ensure reliable performance even during long-term high-intensity operation.
The gears of new energy vehicles provide solid technical support for the performance improvement and green travel of new energy vehicles through efficient power transmission, variable speed regulation, transmission efficiency improvement, noise and vibration, driving stability guarantee, and extended service life.
