The gears of a beach buggy are key components in its transmission system, working together to transmit power and enable it to travel on various terrains. Gears are usually made of high-strength metal materials, such as alloy steel, to withstand high torque and frequent use. The gear system of a beach buggy may include the following main parts:

1. Main transmission gear: located on the engine output shaft, responsible for transmitting the engine's power to the transmission.

2. Variable speed gears: Inside the gearbox, different sizes of gear combinations are used to achieve speed changes and torque adjustments for the beach buggy.

3. Differential gear: In a four-wheel drive beach buggy, the differential allows the left and right wheels to rotate at different speeds, which is crucial for maintaining vehicle stability during turns.

4. Drive shaft gear: connects the differential and the wheels, ultimately transmitting power to the drive wheels of the beach buggy.

5. Reverse gear: enables the beach buggy to achieve reverse function.

The design and manufacturing of beach bike gears require precise engineering techniques to ensure that they can withstand harsh working environments such as sand, mud, and water. Regular maintenance and lubrication are key to maintaining the good operating condition of the gear system, including checking gear wear, replacing lubricating oil, and tightening loose components. When using a beach buggy, sudden acceleration and sudden braking should be avoided to reduce impact and wear on the gear system.
