The application of gears in automobiles and motorcycles primarily focuses on transmission systems and power delivery. In conventional vehicles, the gearbox contains multiple sets of gears that can automatically or manually adjust the transmission ratio based on the driver’s needs and driving conditions. This ensures the engine operates at optimal speed under varying velocities, improving fuel efficiency and performance. For example, a lower gear ratio is used during start-up to provide higher torque, while a higher gear ratio is employed at high speeds to reduce engine revolutions and fuel consumption.

Electric vehicles (EVs) also rely on similar applications, but due to the characteristics of electric motors, they often require simpler gearbox designs. The material and design of gears significantly impact overall performance. High-strength alloy steel gears resist wear and extend service life, while precise machining ensures smooth operation, reduces noise, and enhances the driving experience.

Additionally, with the development of autonomous driving technology, intelligent control of gears will become a critical direction for future automobile and motorcycle technology.
