[0002] Motorcycles are two- or three-wheeled vehicles driven by gasoline engines and steered by the front wheel operated by handlebars. They are lightweight, flexible, and fast, and are widely used for patrol, passenger and freight transportation, as well as sports equipment. Motorcycles commonly use a combination of sprockets and chains for transmission.

[0003] When a motorcycle is in motion, mud and sand on the road surface are easily thrown out and come into contact with the sprocket. As the sprocket rotates, some of the mud and sand will enter the meshing point between the chain and the sprocket, causing friction and damage to the sprocket. Utility Model Content
