This system utilizes a clutch mechanism that engages automatically based on engine speed. At low speeds, the clutch remains disengaged, allowing the engine to run without driving the output shaft. As engine speed increases, centrifugal force throws weights outward. This outward movement forces contact with the clutch drum, transmitting power through a belt to the driven component. Common examples include go-karts, small motorcycles, and some industrial equipment where a simple, automatic power transmission system is desired.
The automatic engagement provides a smooth start-up, preventing engine stalling under load and reducing wear and tear on both the engine and the driven component. This type of system eliminates the need for complex manual clutching mechanisms, simplifying operation and reducing maintenance requirements. Historically, these systems have played a significant role in various applications, offering a cost-effective and reliable method for power transmission in smaller engines.
