Abstract

A cowling assembly is mounted on a front portion of the frame of a motorcycle. The cowling assembly includes a cowling covering a front portion of the frame, a windshield disposed on and continuously blending into a central upper portion of the cowling, and a pair of air ducts extending along laterally opposite sides of the windshield and having an air inlet for introducing an air flow developed when the motorcycle is running into the cowling and an air outlet for discharging the air flow introduced from the air inlet in a substantially upward direction. The air inlet is positioned near a lower end of the windshield on each side of the cowling, and the air outlet is positioned at an upper end of the cowling.

Claims

1. A cowling assembly, for use on a motorcycle having a frame, comprising:

a cowling adapted to cover a front portion of the motorcycle;

a windshield disposed on and continuously blending into a central upper portion of said cowling;

a pair of air ducts extending along laterally opposite sides of said windshield, each said air duct having;

an air inlet for introducing an air flow developed when the motorcycle is moving into said cowling and;

an air outlet for discharging the air flow introduced from the air inlet in a substantially upward direction;

wherein said air inlet is positioned near a lower end of said windshield on each side of said cowling;

said air inlet is positioned at an upper end of said cowling; and

each of said air ducts is shaped to direct the air flow discharged from said air outlet toward a vertically and longitudinally extending central plane of the motorcycle.

2. A cowling assembly for use on a motorcycle as described in claim 1 wherein:

said pair of air ducts are integrally formed in side portions of said cowling which extend along laterally opposite sides of said windshield.

3. A cowling assembly according to claim 1, wherein said air outlet has an area smaller than that of said air inlet.

4. A cowling assembly according to claim 1, wherein each of said air ducts is of a curved configuration.

5. A cowling assembly according to claim 1, wherein each of said air ducts has a guide disposed in a rear end of the air outlet for deflecting upwardly the air flow discharged from said air outlet.
