Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a radiator device for a water-cooled engine in a motorcycle or other two-wheeled vehicle.

The applicant of the present application proposed a device of this kind in Japanese Patent Application Laid-Open No. 55-140670 filed on the same day, which was designed to be used as a fuel tank, oil tank, air cleaner case, tool box, or other container by straddling the main pipe extending rearward from the head pipe. We have proposed a type in which the radiator is installed approximately horizontally below the radiator, but in the case of a cam type, if the water inlet of the radiator is provided on the radiator itself, its position will be relatively low and the radiator will be placed above the radiator. Since the container is present, supplying water or inspecting the container through the container is relatively troublesome.

The purpose of the present invention is to obtain a device that does not have the inconvenience of camming.A main pipe 2 extending rearward from a head pipe 1 is provided with a container 3 spanning the pipe 2, and a container 3 is provided below the container 3. In a radiator device for a two-wheeled motor vehicle having a radiator 4 on the side, a water supply port 5 is provided on the main pipe 2 and located behind the head pipe 1, and the water supply port 5 is connected to the main pipe 2 and the water supply port 5. A water pipe 7 extending downward within a space 6 previously formed between the container 3
The radiator 4 is connected to the radiator 4 via the radiator 4.

The radiator 4 may be one as in the embodiment shown in FIGS. 1 to 4, or two on the left and right as in the embodiment shown in FIGS. 5 and 6. In the former case, a water pipe 7 is one extending along one side of the main pipe 2, but in the latter case, it is preferable to have two extending from the water supply port 9 and extending along both sides of the main pipe 20. According to this, one common It is advantageous to be able to quickly and reliably supply water to the two radiators 4.4 through the water supply ports 5 of the radiators 4.4.

The main pipe 2 together with the head pipe 1 at its front end and the down tube 8 extending downward from it make up the body frame of the motorcycle as a whole, and in the drawing, 9 is the front wheel, 10 is the steering bundle above it, and 11 is the reinforcement pipe 1 between the down tube 8 and the main pipe 2
2 indicates the lower engine.

The radiator 4 has a somewhat upward slope toward the rear, and above it forms an air guide path 13 that opens forward between the radiator 4 and the container 3, through which air is guided when the car is running. I did it like that.

The water supply port 5 is fixed onto the main pipe 2 via fittings 5a, 5a, and has a removably attached cap 5b on its upper surface, and its position is such that it functions as a fuel tank, for example, as shown in FIG. It is close to the fuel inlet 14 on the top surface of the container 3.

To explain its operation, if you remove the cap 5b on the top surface of the water supply port 5 on the main pipe 2 and inject water,
The sample water is led into the radiator 4 below it through a water pipe 7 connected thereto, and water is supplied to it.

In addition, when there are two radiators 4 on the left and right, each radiator 4 is connected to one common water supply port 5 via each water pipe 7,
Water is quickly and reliably supplied through the water supply port 5, making the work easier and the structure simpler than in the case where a plurality of water supply ports 5 are provided.

In this way, according to the present invention, water can be introduced into the radiator 4 below through the water supply port 5 on the main pipe 2, which is different from the conventional type in which the water supply port is provided in the radiator 4 itself. It has an effect without any inconvenience.
