The rise of electric vehicles (EVs) has become a major trend in modern transportation, and gears play an increasingly important role.

Electric motors power EVs, and the primary function of the gear system is to convert the high-speed rotation of the motor into the low-speed, high-torque output required by the wheels. This process is vital for improving the acceleration performance of EVs. Compared to traditional internal combustion engine vehicles, electric motors can deliver high torque across a wide range of speeds, providing greater flexibility in design. Many EVs adopt a single-speed gearbox, simplifying the drivetrain structure, reducing maintenance requirements, and enhancing efficiency.

With technological advancements, gear design has become more lightweight, utilizing high-strength materials to reduce overall weight and improve energy efficiency. Furthermore, EV energy recovery systems rely on efficient gear operation to convert kinetic energy into electrical energy during deceleration or downhill driving, storing it in the battery and further enhancing overall performance.
