A small, open-wheeled vehicle propelled by an engine, typically a small gasoline engine, relies on a continuous loop of flexible material to transmit power from the engine to the rear axle. This system allows for a simple and efficient transfer of rotational energy, enabling variable speed and torque. A common example is a recreational vehicle used for racing or leisure activities, often featuring a centrifugal clutch for engagement and disengagement of power.
This power transmission method offers several advantages, including relatively low cost, ease of maintenance, and a natural shock-absorbing quality that protects both the engine and the drivetrain from sudden impacts. Historically, similar mechanisms have been used in various applications, from industrial machinery to early automobiles, demonstrating its enduring practicality and adaptability. This straightforward design contributes to its popularity in recreational vehicles, where simplicity and reliability are valued.
