Description

[Detailed description of the invention] This invention is designed to reduce the amount of mud that accumulates, which reduces the cooling performance of the radiator of a water-cooled engine such as a motorcycle.
This invention relates to a mud prevention device for a radiator to prevent intrusion.

A radiator guard with a wire mesh is attached to the front of the radiator of a water-cooled engine mounted on a motorcycle for purposes such as dust prevention, but it is not suitable for off-road use when the motorcycle is traveling on rough terrain such as in competitions. In this case, mud thrown up from the road surface adheres to the wire mesh of the radiator guard, clogging the wire mesh, and mud also enters the radiator, reducing air circulation. As a result, the cooling performance of the radiator decreases.

The present invention has been made to solve the above-mentioned problems.The purpose of the present invention is to install a plurality of elastic plates in parallel in an inclined manner in front of the wire mesh of the radiator guard, and to By overlapping each other, the elastic plates prevent mud from adhering to the wire mesh, and by overlapping the opposing ends of the elastic plates with a gap in the front and back direction, the gap is reduced. This is a radiator prevention system that ensures air flow through the elastic plate, and even if mud adheres to the elastic plate, it is automatically removed by the self-vibration of the elastic plate, which is made of an elastic material such as rubber, caused by engine vibration. We are here to provide mud equipment.

A preferred embodiment of the present invention will be described below in detail with reference to the accompanying drawings.

FIG. 1 is a side view of an off-road motorcycle to which a device according to the present invention is applied. A water-cooled engine 2 is mounted on a vehicle body frame 1, and the engine 2
A cooling radiator 3 is placed in front of a fuel tank 4, and a radiator cover 5 covers the outside thereof.
In this way, the radiator 3 is located in the upper part of the vehicle body, behind the head pipe 7 that pivotally holds the front fork 6 for suspension of the front wheels so as to be rotatable left and right, and is connected to the engine 2 via water pipes 8 and 9. Ru.

As shown in FIG. 3, the radiator 3 is assembled to the side surface of the center frame 12 with bolts 10 and 11 at the upper and lower bracket parts 3a and 3b, and as shown in FIG.
3 is attached with screws 14... An opening 13a is formed in the front surface of the box-shaped radiator guard 13, and a wire mesh 15 is provided in the opening 13a facing the radiator 3.

A plate-shaped mud guard 16 made of an elastic rubber material is fixed to the front surface of the radiator guard 13 by adhesive or the like, and the mud guard 16 is integrally provided with a plurality of elastic plates 17. . That is, the elastic plates 17 are integrally formed with the mound guard 16 by die processing or punching during the molding process of the mound guard 16, and are fixed in the vertical direction to the longitudinal direction by fixing the mound guard 16 to the radiator guard 13. The elastic plates 17 arranged in the left-right direction are arranged in parallel in front of the wire mesh 15, and the right end 17a of each elastic plate 17...
As shown in FIG. 4, the elastic plates 17 are formed by molding from the main body of the mud guard 16, so the elastic plates 17 are arranged diagonally in front of the wire mesh 15 with the opening side facing outward from the vehicle body.

Figure 5 shows elastic plates 17-1 and 17 adjacent to the left and right.
-2 detailed positional relationship, Matsudo Guard 16
As mentioned above, elastic plates 17-1 and 17-2 are connected to the main body of
The right end portions 17-1a and 17-2a are formed, and the left end portions 17-1b and 17-2b are formed as the mud guard 16.
is connected to the main body of the The left end portion 17-1b of the elastic plate 17-1 and the right end portion 17-2a of the elastic plate 17-2 facing the left end portion 17-1b are separated from each other in the front-rear direction by a gap S. The opposing ends 17-1b and 17-2a overlap each other over a length l in the left-right direction.

Therefore, when the motorcycle runs, air flows through the gap S and the opening 16a formed in the mud guard 16 behind the elastic plate 17 as shown by the arrow.
Make sure to check the wire mesh 15 and even the radiator 3 behind it.
At the same time, mud that is thrown up from the road surface and collides head-on with the elastic plate 17 can pass through the gap S and the opening 16a because there is an overlapping part of length l. In other words, mud is blocked by the mud guard 16 and does not adhere to the wire mesh 15. The mud adheres to the elastic plate 17, which is made of rubber elastic material,
Since the elastic plate 17 self-vibrates due to engine vibrations, road vibrations while the motorcycle is running, etc., mud is naturally removed from the elastic plate 17. Also, the mud is elastic plate 1
When the elastic plate 17 collides with and adheres to the radiator guard 13, the elastic plate 17 bends and deforms to absorb and alleviate the collision force, so that the radiator guard 13 can be protected.
7 is caused by the elastic deformation caused by the adhesion of mud.
However, once the mud is removed as described above, the elastic plate 17 returns to its original state due to its own elastic restoring force, and the gap S is again in a communicating open state. Become.

Although the above embodiments are cases in which the device according to the present invention is applied to a motorcycle, the present device can also be applied to a radiator of a water-cooled engine other than a motorcycle.

As is clear from the above explanation, according to the present invention, a plurality of elastic plates are installed in parallel in a slanted manner in front of the wire mesh of the radiator guard, and the opposing ends of adjacent elastic plates are overlapped with each other with a gap in the front and back direction. Although the gaps provide good air circulation, the overlap prevents mud from penetrating or adhering to the wire mesh, allowing the radiator to exert its original cooling performance. Furthermore, even if mud adheres to the elastic plate, the mud can be removed by itself because the elastic plate self-vibrates due to engine vibration or the like.
