1. An air guide device for a vehicle comprising: a chassis frame; an engine being mounted on said chassis frame; and an engine guard being arranged near said engine and protruding from the engine and the chassis frame spaced apart toward a side of the chassis frame so as to protect the engine, said engine guard further including: a hollow portion formed into a substantial U-shape, said hollow portion including a horizontal segment extending transversely away from a side of said chassis frame in a horizontal direction, a vertical segment extending generally parallel to the side of the chassis frame, and an inclined segment extending at an inclined angle downwardly away from a lower portion of said vertical segment and toward said chassis frame, wherein an inner side of said engine guard at the chassis frame is formed with the inclined segment opposing an exterior surface of said engine.
6. An air guide device for a vehicle comprising: a vehicle main body having a chassis frame and an engine; an accessory storage box being secured to a rear side of said vehicle main body; and an accessory storage box guard being arranged near said accessory storage box, said accessory storage box guard being spaced apart from the accessory storage box to protect the accessory storage box and protruding from a side of the chassis frame, wherein an inner side of said accessory storage box guard is formed with a flat surface opposing said accessory storage box and forming an air passage between said accessory storage box and said accessory storage box guard and said accessory storage box guard further includes: said flat surface forming a vertical segment extending generally parallel to the side of the chassis frame, and an inclined segment extending at an inclined angle downwardly away from a lower portion of said vertical segment and toward said accessory storage box.
11. An air guide device for a vehicle comprising: a vehicle main body having a chassis frame and an engine; an accessory storage box being secured to a rear side of said vehicle main body; an accessory storage box guard being arranged near said accessory storage box, said accessory storage box guard being spaced apart from the accessory storage box to protect the accessory storage box and protruding from a side of the chassis frame, wherein an inner side of said accessory storage box guard is formed with a flat surface opposing said accessory storage box; and an engine guard being arranged near said engine and protruding from the engine and the chassis frame spaced apart toward a side of the chassis frame so as to protect the engine, said engine guard further including: a hollow portion formed into a substantial U-shape, said hollow portion including a horizontal segment extending transversely away from a side of said chassis frame in a horizontal direction, a vertical segment extending generally parallel to the side of the chassis frame, and an inclined segment extending at an inclined angle downwardly away from a lower portion of said vertical segment and toward said chassis frame, wherein an inner side of said engine guard at the chassis frame is formed with the inclined segment opposing an exterior surface of said engine.
19. The air guide device according to claim 11, wherein said accessory storage box guard further includes: said flat surface forming a vertical segment extending generally parallel to the side of the chassis frame, and an inclined segment extending at an inclined angle downwardly away from a lower portion of said vertical segment and toward said accessory storage box.
FIGS. 5(a)–5(b) are perspective views of an engine guard of a motorcycle according to a preferred embodiment of the present invention;
FIG. 4 is a partial front elevation of an engine guard fixing part and an engine of a motorcycle according to a preferred embodiment of the present invention. FIG. 5 is a perspective view of an engine guard of a motorcycle according to a preferred embodiment of the present invention. FIG. 6 is a front elevation view for showing an engine guard of a motorcycle according to a preferred embodiment of the present invention. As shown in FIGS. 4 to 6, the engine guard 40 includes a hollow part 45 entirely formed into a substantial U-shape, solid fixing segments 46, 46 fixed at both ends of the hollow part 45 and filled with material inside, and a connecting pipe 47 connecting the fixing segments 46, 46 to each other. As shown in FIG. 4, the hollow part 45 includes a horizontal segment 48 extending in a horizontal direction to cover the upper part of the head cover 9a of the engine 9 when the engine cover 40 is fixed to the chassis, a vertical segment 49 curved to cross at a right angle with the horizontal segment 48 and extending in a vertical direction to cover the side part of the head cover 9a, and an inclined segment 50 curved approximately 45° from the vertical segment 49 and extending in an inclined, downward direction to cover the lower part of the head cover 9a. The hollow part 45 has an irregular sectional shape formed into a bulge work in which a certain pressure is applied inside the raw material under utilization of liquid to perform a bulged-out molding, wherein both ends are connected to the fixed segments 46, 46 formed by forging, e.g., through welding. In addition, the fixed segments 46, 46 and the connecting pipe 47 are also connected with welding.
A reinforcing pipe member 51 is embedded inside each of the horizontal segment 48 of the hollow part 45 and the inclined segment 50 while being fixed to the fixed segments 46 by a proper fixing method such as a welding and the like. The engine guard 40 having the aforesaid configuration is fixed to the chassis by a method wherein the threaded hole 46a formed at the upper fixed segment 46 coincides with a threaded hole integrally formed with the engine hanger 28 of the upper frame 24 and at the same time the threaded hole 46b formed at the lower fixed segment 46 coincides with the threaded hole formed at the side frame 35. The threaded holes are used to fix the engine guard 40 to the chassis by bolts 43, 44 (refer to FIGS. 3 and 4).
FIG. 7 is a partial top plan view in section of an engine guard fixing part of a motorcycle and a part of an engine according to a preferred embodiment of the present invention. As shown in FIG. 7, the preferred embodiment is made such that the vertical segment 49 of the hollow part 45 is formed into a trapezoid section with a major axis inclined in respect to the forward or rearward direction. With this arrangement, the vertical segment 49 is formed such that an inclined surface 52 is formed at a segment where it enters inside the chassis when it is fixed to the chassis. The inclined surface 52 is inclined such that it may oppositely face against the head cover 9a of the engine and it is expanded gradually outside the chassis as it is directed rearwardly of the chassis.
Thus, in accordance with the air guide and engine guard device of the motorcycle having the aforesaid configuration, the inclined surface 52 is formed to be oppositely faced against the head cover 9a of the engine 9 inside the chassis of the engine guard 40 and inside the chassis of the vertical segment 49 of the hollow part 45. In particular, the inclined surface 52 of the vertical segment 49 forms the air guide passage Da between these elements together with the inclined surface 9aa of the cylinder head 9a of the engine 9. Accordingly, when the motorcycle runs, the air striking against the front part of the engine 9 through the side part of the front wheel 7 flows through the air guide passage Da and rearwardly along the side part of the engine 9 so as to form a series of engine cooling airflows.
