Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a tank mounting structure for mounting a recovery tank or the like for engine cooling water of a motorcycle.

[Prior art]

Generally, in a motorcycle, an engine cooling water recovery tank is placed inside a side cover below the seat, and is attached to a stay welded to the vehicle body frame using screws or the like. When installing this recovery tank, there is always some dimensional error when attaching the stay to the vehicle body frame, so to prevent the tank from interfering with the side cover due to the dimensional error and making installation impossible, it is necessary to install the tank outside the tank. Be sure to install 1 between the side surface and the inner surface of the side cover.
It has become common to design so that there is a gap of about 0 to 15 mm.

However, if such a large gap is formed, the tank capacity must be reduced by the amount of the gap, which is negative for increasing the tank capacity.

[Purpose of the invention]

An object of the present invention is to provide a tank mounting structure for a motorcycle that can minimize the gap between the tank and the side cover, thereby increasing the tank capacity.

[Structure of the invention]

The present invention, which achieves the above object, is a motorcycle in which a tank is disposed inside a side cover, in which the tank is fixedly attached to the side cover.

〔Example〕

Hereinafter, the present invention will be explained with reference to embodiments shown in the drawings.

In FIG. 1, numeral 1 is a wide aluminum body frame, 2 is a water-cooled engine, and 3 is a seat. A resin side cover 4 is attached to the lower side of the seat 3, and a recovery tank 5 for engine cooling water is disposed inside the side cover 4. This recovery tank 5
is connected by a hose 11 to a cooling water inlet 13 provided at the top of the radiator 12 .

As shown in Figure 2.3, there are several mounting brackets 9 degrees around the recovery tank 5.
are formed, and these mounting brackets 9゜---------,
9 is a rod 10 integrally molded on the inner surface of the side cover 4.
, -.-110 and fixed by tapping or heat caulking.

In this mounting state, the gap t between the outer surface of the recovery tank 5 and the inner surface of the side cover 4 is as small as about 2 to 3 mm.

The side cover 4 to which the recovery tank 5 is attached in this manner is fixed to the seat rail 1a constituting the vehicle body frame, either directly or indirectly via a mounting bracket or the like.

According to the tank mounting structure described above, the recovery tank 5 is not mounted via a stay welded to the vehicle body frame (seat rail, etc.) as in the past, but is mounted directly to the inner surface of the side cover 4, so that the recovery - Even if the gap t between the tank 5 and the tank 5 is made extremely small, the recovery tank 5 will not become impossible to install due to interference between the two. In other words, with the conventional mounting structure, it was necessary to provide a gap of about 10 to 15 mm to allow for dimensional errors when attaching (welding) the stay to the vehicle body frame, whereas with the above mounting structure, it was necessary to provide a gap of about 2 to 3 mm. Since a gap is sufficient, it can be reduced to about 115. Therefore, the capacity of the recovery tank 5 can be increased by the amount by which the gap is made smaller.

Further, according to the above-mentioned mounting structure, the recovery tank and the side cover can be sub-assembled and then assembled on a line, so that the assembly work efficiency can be significantly improved.

Additionally, if the body frame is made of aluminum, welding is difficult, so the traditional structure of welding the stay to the body frame and attaching the recovery tank to the stay inevitably increases welding costs. However, with the above mounting structure, such welding costs can be reduced.

In the above-mentioned embodiment, the case of a recovery tank for engine cooling water was exemplified, but the present invention is not limited to such a water tank. It is also applicable to other tanks that may be attached.

〔Effect of the invention〕

As described above, the present invention provides a motorcycle in which the tank is disposed inside the side cover, in which the tank is fixedly attached to the side cover, so that even if the gap between the tank and the side cover is significantly reduced, Interference between the two will not make it impossible to install the tank (and by making this gap smaller, the tank capacity can be increased by that much).
