Description

[Detailed Description of the Invention] (Field of Industrial Application) This invention relates to a reserve tank for replenishing a radiator with cooling water in a two-wheeled motor vehicle equipped with a water-cooled engine.

(Prior art) This type of reserve tank is also provided with a liquid level display means, but exposing all of it would spoil the external appearance, so the reserve tank is Generally, it is covered with a cover, and a viewing window is formed only in a portion of the cover that corresponds to the liquid level display means.

Here, the liquid level display means takes advantage of the fact that the reserve tank is made of transparent or semi-transparent resin, and uses, for example, a pair of upper and lower panels that respectively display high and low levels on the side (elevated surface) of the reserve tank. A level observation line is integrally formed, and the liquid level is confirmed by comparing the confirmation line and the liquid level through a side confirmation window. Such a technique is disclosed in, for example, Japanese Utility Model Application No. 52-137873.

With the above type, there is a confirmation line on the side, so the driver has to lower his/her posture to check it.Also, since the liquid level display means is provided on the side of the tank, it is difficult to actually check the level. Confirmation is done by visually comparing the liquid level with reference to the confirmation line, and therefore, due to this comparative confirmation method, the level cannot be detected intuitively.

In addition, conventionally, as disclosed in Utility Model Application Publication No. 53-51730, instead of the side of the tank,
It is also known that an overhang with an inclined upper surface is formed along the side of the tank, and a liquid level display means is provided on the upper surface of the overhang. This allows you to visually check the liquid level from either diagonally above the tank or directly above it.

By the way, as mentioned above, in a motorcycle, it is important not to spoil the external appearance, and for this purpose, it is desirable to cover the reserve tank with a cover as much as possible.

From this point of view, although the method shown in the above-mentioned Japanese Utility Model Publication No. 53-51730 is effective in making it easy to visually check the liquid level when the reserve tank is arranged with almost the entire part exposed, As a liquid level display device for a motorcycle reserve tank that attempts to improve the external appearance by covering most of the tank with a cover, it is not very effective as it only requires some ingenuity in forming an overhang. do not have.

(Purpose of the invention) This invention was made in view of the above circumstances,
Automatic 2 allows you to easily and intuitively check the liquid level while standing without compromising the appearance.
The purpose is to provide a reserve tank for cooling water for wheeled vehicles.

(Structure of the invention) In order to achieve the above object, this invention projects a transparent or translucent reserve tank forward of the engine and is placed below the radiator. To,
The Louis level display surface and the low level display surface are formed in a step-like manner so that they are both horizontal planes, and a confirmation window is provided on the front end upper surface of the cowling that covers the reserve tank at a location corresponding to the level display section. is forming.

(Example) Hereinafter, an example of this invention will be described with reference to the drawings.

FIG. 1 shows a right side view of a two-wheeled motor vehicle. In the figure, 1 is a vehicle body on which a water-cooled engine 2 is mounted. 3 is a fuel tank, and a seat 4 is provided at the rear of the fuel tank. A fairing 5 is attached to the front part of the vehicle body 1, while a radiator 6 is installed at a position corresponding to the front part of the engine 2.
is installed.

In such a motorcycle, a resin cowling 7 is attached to the front bottom, and in this case,
A reserve tank 8 for cooling water is installed within the cowling 7.

That is, in FIG. 2, reference numeral 9 denotes a tank mounting bracket, and this bracket 9 is fixed to the inner surface of the bottom wall 10 of the cowling 7 at several locations by fasteners 11. Both sides of the front end of this tank mounting bracket 9 are upright, and the left and right upright portions 1
The reserve tank 8 is placed on a tank receiving part 13 formed at the upper end of the tank 2, and is tightened from above by a fitting 14. Therefore, a pair of upper and lower recesses 15 are formed on the left and right sides of the reserve tank 8.

In such a reserve tank 8, the top wall 16 is tilted forward, and a water supply port 18 with a cap 17 is provided on the slope.
A low level display surface 19 and a low level display surface 20 one step lower than the low level display surface 19 are each formed in a step-like horizontal plane at the front end of the display.

On the high level display surface 19, as shown in FIG.
There is a high-level embossed mark 21 embossed in the shape of an English letter H, and a low-level embossed mark 22 embossed in the shape of an English letter L on the low-level display surface 20.
are provided integrally with a reserve tank 8 made of transparent (or semi-transparent) resin.

The protruding state is shown in FIG. 4, in which the raised marks 21 and 22 are made to protrude upward under uniform wall thickness.

On the other hand, the cowling 7 is made of resin, and as shown in FIG. 3, the left and right side walls 23 are curved.
23, and a front end upper surface portion 24 between both side walls 23, 23 is shaped to cover the front end portion of the reserve tank 8 from above, and corresponds to the upper side of both raised marks 21, 22 on this front end upper surface portion 24. By forming a rectangular confirmation window 25 at the location where the image is displayed, the embossed marks 21 and 22 can be confirmed from above (actually, from diagonally above).

Note that an opening 26 is formed above the rear end of the front end upper surface portion 24, and cooling water can be replenished through this opening 26.

Therefore, in the above configuration, when the liquid level of the cooling water containing the coolant is at level a as shown in FIG.
is green due to the color of the coolant, and both the raised marks 21 and 22 are embossed greener than the level display surfaces 19 and 20 due to the green color of the coolant. At this time, it is intuitively clear that the cooling water is at a high level.

Next, when the level drops to b, the green display on the high level display surface 19 and the high level embossed mark 21 disappears, and only the low level display surface 20 and the low level embossed mark 22 are displayed in green, and at this time, the cooling water is in the low level range.

Further, when the level drops to c, both the level display surfaces 19 and 20 and the raised marks 21 and 22 become transparent, and at this time the cooling water is empty or nearly empty.

The level of each cooling water can be checked while the driver is standing, and since it is a simple step-by-step check method rather than a comparative check method like the conventional method mentioned above, You can easily detect the level even from Further, in the above embodiment, since the confirmation window 25 is not arranged in a place visible from the side of the vehicle, the design is excellent.

Note that if the reserve tank 8 is provided inside the fairing 5 shown by A in FIG. 1 or inside the cover of the seat 4 shown by B in FIG.
Not only is it necessary to form a confirmation window in the cover of the seat 4, but also it is difficult to visually check the liquid level while driving or standing with a confirmation window provided in such a location.

(Effects of the invention) As explained above, according to this invention, the reserve tank is made to protrude ahead of the engine, is placed below the radiator, and the liquid level is maintained at the front of the upper wall of the reserve tank. Since a display surface is formed, the driver can easily check the liquid level from above while standing.

In addition, each level display surface is formed of two stepped horizontal surfaces, and these horizontal display surfaces are marked with a high level display mark and a low level display mark, making it possible to visually check the liquid level intuitively. can.

Moreover, since the reserve tank is covered with a cowling and the confirmation window is formed only in the area corresponding to the level display, the confirmation window is almost invisible, especially when viewed from the side, making it a great motorcycle. The appearance can be improved.
