Description

[Detailed Description of the Invention] This invention relates to an improvement of a radiator air guide device for a motorcycle equipped with a water-cooled engine.

When installing a water-cooled engine on a motorcycle,
Generally, the radiator is placed in front of the frame in front of the engine, facing forward, and the wind from driving hits the radiator to cool the engine. However, in front of the radiator are the front forks, front wheels, and front mudguards, and the front mudguard in particular is located in the center front of the radiator and has a large surface area, blocking the wind from flowing into the radiator. For this reason, an outward-facing louver is provided on the front side of the radiator to guide the wind flowing outside the front wheel mudguards to the radiator to compensate for the lack of cooling air. However,
If the vehicle is driven on rough roads in the rain, the louvers may collect mud, causing mud jams and resulting in insufficient cooling.

This idea is an improvement based on these points.
Embodiments of the present invention shown in the drawings will be described below.

A plurality of louvers 2 are arranged to spread outward on the front side of a radiator 1 mounted forward on the front part of a vehicle body. Especially on the outside, a large louver 3 that widens outward is arranged. In addition, between the louver 2, the large louver 3, and the radiator 1, be careful not to let stones or large chunks of mud hit the radiator 1.
A wire mesh 4 is attached. Further, on the rear side of the large louver 3, a window hole 5 is provided on the side surface to open into the space between the wire mesh 4 and the radiator 1. A side louver 6 is provided outward from the rear side of the window hole 5 so as not to protrude outward beyond the large louver 3. 7 indicates the front wheel.

However, louver 2 and large louver 3 are
The running wind flowing on both outsides of the front wheels 7, front wheel mudguards, etc. is received and flows to the radiator 1 to cool the radiator 1 with a large amount of air. The side louver 6 receives the traveling wind that passes through the outside of the large louver 3 and flows into the radiator 1 through the window hole 5.
aids cooling. When driving on a rough road in the rain, the louver 2 and the large louver 3 collect mud thrown up by the front wheels 7, and the mud adheres to the wire mesh 4 stretched on the rear side. This causes clogging and impedes air flow. However, even in this case, since the side louver 6 is located at the rear of the large louver 3, there is little mud adhesion and the running wind flows through it, which helps cooling. In this way, even when the amount of traveling air received from the front is reduced, cooling air flows from the side louvers 6 through the window holes 5 to the radiator 1, thereby resolving insufficient cooling.

As explained above, this idea places a plurality of louvers with their front ends expanding outward on the front side of the radiator, places a large louver on the outside, and then stretches a wire mesh between the louvers and the radiator. A window hole that opens into the space between the wire mesh and the radiator is provided on the rear side of the large louver, and the side louver is placed outward so that it does not protrude beyond the large louver from the rear side of the window hole. The side louvers catch wind from the vehicle that passes through the outside of the louver and sends it to the radiator through the window holes, helping to cool the vehicle. In addition, in rainy weather, the side louvers do not protrude outwards as much as the larger louvers, so they are less likely to be hit by muddy water, and are effective in cases where the front side becomes clogged with mud, resolving insufficient cooling. .

Claims (1)

[Scope of utility model registration request] A plurality of louvers whose front ends widen outward are arranged on the front side of the radiator, and a large louver whose front end widens outward is arranged on the outside, and a wire mesh is stretched between the louvers and the radiator. This motorcycle radiator air guide device is characterized in that a side louver is provided on the rear side of the large louver so as not to protrude outward beyond the large louver from the rear side of a window opening between the wire mesh and the radiator.
