Description

[Detailed Description of the Invention] a. Field of Industrial Application The present invention relates to an amphibious saddle type vehicle.

b. Prior Art and Problems of the Present Invention Conventionally, various types of vehicles have been devised for off-road use. However, in order to achieve amphibious functions in such off-road vehicles, it is usually necessary to attach large floats to obtain buoyancy. In off-roading, it is quite possible to cross rivers where bridges have never existed before, and it has been hoped that an amphibious off-road vehicle equipped with a small float would appear. Furthermore, in water transportation, it has been desired to provide a propulsion force for traveling on water without switching to a special screw or the like.

c Means for Solving the Problems The present invention was made in view of the above circumstances, and includes a low-pressure balloon tire 2 and a predetermined tire installed between the front fender 4 and rear fender 5 to obtain buoyancy. A float 3, a propulsion fin 7 provided on the inner circumference of the wheel 1, and a drive shaft 9
A guide plate 8 is fixed to the frame, and a propulsion discharge hole 10 is provided behind the guide plate 8. The water sent by the propulsion fin 7 is sent into the guide plate 8 through the water outlet hole 6, and the water collected by the guide plate 8 is sent to the propulsion discharge hole 1.
To provide an amphibious straddle-type vehicle which obtains propulsive force for running on water by discharging water from zero.

d. Embodiments The present invention will be described below with reference to embodiments shown in the accompanying drawings.

Figures 1a and 1b show an embodiment of a straddle-type vehicle according to the present invention, in which 1 is a wheel, 2 is a low-pressure balloon tire, and 3 is a float.

The float 3 is provided by utilizing the dead space between the front fender 4 and the rear fender 5, and has a predetermined size to obtain buoyancy. In this straddle-type vehicle, the low-pressure balloon tire 2 itself has a large buoyancy, so the float 3 assists the buoyancy.

Next, FIGS. 2a and 2b show a device for obtaining propulsion force when the above-mentioned straddle-type vehicle runs on water, and in the figures, 6 is a water drainage hole, 7 is a propulsion fin,
8 is a guide board.

A predetermined number of the propulsion fins 7 are spirally provided on the inner periphery of the wheel 1, and the water drainage holes 6
Two types of large and small types are provided along the driver shaft 9. The guide plate 8 is fixed to the frame and has a propulsion discharge hole 10 at the rear.

The straddle-type vehicle configured as described above obtains buoyancy through the low-pressure balloon tires 2 and the float 3. on the other hand,
The water guided by the action of the propulsion fins 7 that rotate together with the wheel 1 is directed from the water outlet hole 6 to the guide plate 8.
Send it inside. The water sent in is collected by the guide plate 8 and discharged from the rear propulsion discharge hole 10. As a result, the straddle-type vehicle according to the present invention obtains propulsive force.

e Effects As mentioned above, the straddle-type vehicle according to the present invention has the following effects:
Since the low-pressure balloon tire 2 itself has a large buoyancy, sufficient buoyancy can be obtained by simply attaching a small float 3 to assist the buoyancy. Therefore, there is no need for a large float;
It does not protrude from the vehicle width and is suitable for practical use. Also, when installing the front fender 4
The dead space between the rear fender 5 and the rear fender 5 can be effectively utilized.

Furthermore, the straddle-type vehicle according to the present invention can configure a propulsion device for traveling on water with minimal changes without installing a screw, etc., greatly expanding the range of off-road activities of the straddle-type vehicle. . Furthermore, since the changes are minimal, the performance as a conventional straddle-type vehicle will not deteriorate.
