Bicycle free-wheel.
The blue sprocket receives motion from the pedaling bicyclist. The yellow hub rotates only when the sprocket rotates clockwise.
Clockwise rotation of the yellow hub has no influence to the blue sprocket.
The red pawl is always pressed toward the sprocket's teeth by a spring. In reality two pawls are used.
