Oil cooling structure for a vehicle

A cooling structure for a vehicle comprising:

• a cooler positioned to cover a front surface and right and left side surfaces of a head pipe positioned in front of a fuel tank;
• a first conduit for connecting an output for a coolant for an engine to an inlet of said cooler;
• and
• a second conduit for connecting an inlet for a coolant for the engine to an outlet of said cooler;
• wherein at least one of said first conduit and said second conduit extends along a lower surface of said cooler and past said right side surface, said front surface, and said left side surface of said head pipe, and wherein said cooler is connected to a coolant tank for receiving cooled coolant prior to being supplied to said engine.

A cooling structure for a motorcycle including a head pipe having a front surface and right and left side surfaces, a frame structure, a fuel tank and an engine comprising:

• a cooler having an upper surface, a lower surface and being positioned to cover said front surface and right and left side surfaces of said head pipe positioned adjacent to said fuel tank;
• a first conduit for connecting an output for a coolant for said engine to an inlet of said cooler;
• and
• a second conduit for connecting an inlet for said coolant for the engine to an outlet of said cooler;
• wherein at least one of said first conduit and said second conduit extends along at least one of said upper surface and said lower surface of said cooler and past said right side surface, said front surface, and said left side surface of said head pipe, and wherein said cooler is connected to a coolant tank for receiving cooled coolant prior to being supplied to said engine.

• wherein at least one of said first conduit and said second conduit extends along at least one of said upper surface and said lower surface of said cooler and past said right side surface, said front surface, and said left side surface of said head pipe, and wherein said cooler is substantially U-shaped and includes a central portion with side sections projecting therefrom, said central portion of said cooler being positioned adjacent to a forward portion of the head pipe and said side sections projecting therefrom being positioned adjacent to side portions of the head pipe, said side sections each including a fastening bracket at an end thereof for attachment to opposing sides of a frame member attached to said head pipe, and further comprising a supporting pin located on each of said opposing side members of said frame, a pair of elastic bushings, and a pair of fasteners for attaching said brackets to said supporting pins with said elastic bushings sandwiched therebetween;
• and
• a coolant tank connected to said cooler for receiving cooled coolant prior to being supplied to said engine, said coolant tank being formed in portions of said frame member of said motorcycle for receiving cooled coolant from said cooler and communicating the cooled coolant to a point adjacent to said engine for supply thereto, said frame member having opposed first and second sides, said first conduit and said second conduit each being routed past said second side of said frame member.
