What are the characteristics of Electric car model gear?

Electric vehicle model gears are crucial core components in the electric vehicle transmission system, and their performance directly affects the power transmission efficiency and driving stability of the electric vehicle.

Advantages

High strength and wear resistance: Metal materials excel in mechanical properties, enduring high loads and fast transmission, ensuring longevity and reliability.

High precision: Precision machining achieves high-accuracy gear manufacturing, meeting the stringent transmission system requirements of new energy vehicles.

Vibration and noise reduction: Optimized gear tooth shape and surface treatments minimize transmission noise, enhancing driving comfort. S

elf-lubricating properties: Surface coatings or lubrication designs reduce friction and lower maintenance costs.

It has wide applications in electric vehicle transmission systems:

Reducer: converts the motor's high-speed and low torque output into low-speed and high torque, driving the wheels to rotate.

Drive motor: It serves as a connecting component between the motor and the wheel, transmits power.

Differential: realizes independent driving of left and right wheels and improves driving stability.
