Description

[Detailed description of the invention] [Industrial application field] The present invention relates to an amphibious vehicle.

[Conventional technology]

As one of the special vehicles, along with Vans for driving,
There is an amphibious vehicle that is equipped with a propulsion device for water navigation and is capable of traveling not only on land but also on water.

[Problem to be solved by the invention]

By the way, some of the above-mentioned amphibious wheels have a small body shaped like a ship's body in order to obtain sufficient buoyancy on water. However, since such amphibious vehicles have extremely unique shapes and structures, productivity cannot necessarily be said to be good.

In view of the above-mentioned circumstances, an object of the present invention is to provide an amphibious wheel that can obtain sufficient buoyancy during water navigation and has good productivity. The purpose is to provide an amphibious vehicle capable of

(Means for Solving the Problems) Accordingly, in the present invention, a front float element and a rear float element are provided in a straddle type vehicle so as to be spaced apart from each other in the front and rear directions across r1 in the outer region of the step of the vehicle. In addition, an amphibious vehicle was constructed by providing a propulsion device for water navigation on the saddle type vehicle.

[Effect]

According to the above configuration, sufficient buoyancy can be obtained when navigating on water due to the function of the float, and an amphibious vehicle can be obtained by simply adding a float and a propulsion device for water navigation to existing straddle-type wheels. Furthermore, since no float is located in the space outside the step, it is possible to get on and off the vehicle smoothly.

〔Example〕

Hereinafter, Kikomei will be explained in detail based on the drawings.

Figure 1.2 shows an amphibious wheel according to the present invention.

This amphibious wheel 1 is provided with a float 31F and a float 3LR in the left side area of the straddle type four-wheel vehicle 2, and a float 3RF and a float 3RR in the right side area, and further includes the straddle type four-wheel vehicle 2 (hereinafter referred to as , a water navigation propulsion device 4 is provided at the rear of the bottom of the vehicle body 2.

In addition, floats 3 located on the left and right front sides of the vehicle body 2

On the other hand, a rear float element 3R is constituted by a float 3LR and a float 3RR located on the left and right rear sides of the vehicle main body 2.

The above flows 1 to 3LF, 3LR1 and 3RF.

3RR each has a vibe frame 51 as shown in the figure.
Vehicle body 2 via F, 5LR1 and 5RF, 5RR
is attached to. The above vibe frame 51F is
It has a front vibrator 5LFa and a rear vibrator 5LFb, each vibrator 5LFa.

5LFb is bolted to the front carrier 2a1 of the wheel body 2 and the vehicle body frame 2b, respectively, as shown in FIG. 3.4. Further, the vibe frame 5LR has a front vibe 5LRa and a rear vibe 5LRb, each of which has a front vibe 5LRa and a rear vibe 5LRb.

5LRb is bolted to the left step 2cL and rear carrier 2d, respectively. On the other hand, the vibe frame 5RF and the vibe frame 5RR also have a front vibe 5RFa, a rear vibe 5RFb, and a front vibe 5.
RRa, W part has a vibe 5RRb, and each vibe 5RFa.

5RFb, 5RRa, and 5RRb are bolted to the front carrier 2a, the vehicle body frame 2b, the right step 2CR, and the rear carrier 2d, respectively.

Here, as is clear from the figure, float 31F, float 3LR1, flow 1-3 RF and float 3R
R is the outer area space (second
lower area in the figure) and outer area space of right step 2cR (
In other words, the front float element 3F and the rear float element 3R are arranged on the outer side of the left step 20L and the right step 2cR. They are placed spaced apart from each other across the area.

In addition, the float 31F and the float 3RF, and the float 3LR and the float 3RR are arranged symmetrically on both sides of the left-right center 1DO-O of the vehicle body 2, respectively, and the float 31F and the float 3RF are arranged symmetrically on both sides of the left-right center 1DO-O of the vehicle body 2. ~31F and float 3LR, and float 3RF and float 3RR are respectively connected to vehicle body 2.
They are arranged at substantially symmetrical positions across the longitudinal center mp-p passing through the center of gravity G of the vehicle.

Furthermore, each float 3LF, 3LR, 3RF.

3RR is for each vehicle 2F, 2F, and 2R when the amphibious vehicle 1 is on the water, as shown in FIG.

It is installed at a height such that approximately the center of 2R is located at water surface z-7. In addition, the above floats 31F and 3L
As described above, R, 3RF, and 3RR generate sufficient buoyancy to float the vehicle 1 on the water.

On the other hand, the engine 10 mounted on the vehicle body 2 is provided with a drive sprocket 11 at the end of its drive shaft 10a. Further, a driven sprocket 13 is provided at the end of an input shaft 12a of a gear box 12 provided at the rear of the engine 10, and a chain 14 is wound between these sprockets 11, 13. .

Behind the gear box 12, there is a main duct body 4a and an impeller 4b housed within the body 4a.
A propulsion device 4 for water navigation is provided.

The main duct body 4a is fixed to a gear box 12, and the impeller 4b is fixed to a propeller shaft 12b that is linked to an input shaft 12a via a pair of bevel gears (not shown). Further, at the rear of the body 4a, a ladder duct 4C is attached to bolts 4d and 4.
It is supported so as to be swingable from side to side, as shown by the arrow mark and the arrow R, using d as a support axis. The rudder duct 4C is linked to the steering handle 2e of the vehicle main body 2 by a linking means (not shown), and is swung left and right by the operation of the handle 2e. Furthermore, the water navigation propulsion device 4 is provided on the left-right center BO-O of the axle body 2, and is also provided at a position lower than the center of gravity of the vehicle 1.

When the engine 10 starts operating, the drive shaft 1
The impeller 4b is rotated from 0a via the drive sprocket 11, chain 14, driven sprocket 13, and gear box 12. When the vehicle 1 is on water, water is sucked into the body 4a from the inlet 4e of the main duct body 4a due to the rotation of the impeller 4b, and then the sucked water flows into the rudder duct 4C.
The vehicle 1 travels on water by ejecting backward through the water. Note that, at this time, the direction of the vehicle 1 is changed by operating the steering handle 2e.

By the way, as mentioned above, float 3LF.

Since the 3LR, 3RF, and 3RR are each disposed approximately symmetrically in one direction on the left and right with respect to the center of gravity G, the vehicle 1 can travel very stably on the water. In addition, as mentioned above, during water navigation, each wheel 2F, 2F,
Since the water surface is located approximately in the center of 2R, 2R, each of the above wheels 2F, 2F.

By using the rotations of 2R and 2R as propulsive force, the navigation speed on water can be increased.
On the other hand, when the vehicle 1 is on land, the engine 10 operates to drive the wheels 2 through a power transmission mechanism (not shown).
R and 2R are rotationally driven, thereby causing the vehicle 1 to travel on land.

By the way, the driver steps from the side of vehicle 1 to step 2cL.
Alternatively, step onto step 2cR and get into vehicle 1. From vehicle 1, step onto step 2CL or 2cR and get off to the side of the vehicle. Here, as mentioned above, the flow h 3 LF and the float 3LR1 or the float 3
RF and float 3RR are placed apart from each other across the space outside the step, so the driver can
.

The user can get on and off the vehicle 1 without being obstructed by 3LR, 3RF, and 3RR.

〔Effect of the invention〕

As detailed above, the amphibious vehicles related to Honkomei are:
A saddle type vehicle is provided with a front float element and a rear float element spaced apart from each other across a space outside the step, and a water navigation propulsion device is provided on the saddle type vehicle. ing. Therefore, sufficient buoyancy during water navigation can be obtained through the function of the float, and an amphibious vehicle can be manufactured by simply adding a float and 8 propulsion units for water navigation to an existing saddle-type vehicle. As a result, productivity is improved. In general, since no floats occupy the space outside the step, the driver can smoothly get on and off the vehicle without being disturbed by anyone.

In this example, the front float element and the rear float element are composed of two separate floats placed on the left and right sides of the vehicle body, respectively. Of course, it is also possible to configure each of them with one float, and for example, the front and rear float elements may be configured with floats each having a U-shaped planar shape surrounding the front and rear parts of the vehicle body, respectively.

In addition, in this example, 1, the propulsion device is driven by an engine as a drive source for traveling, but as a propulsion device,
It goes without saying that a device driven by a completely separate engine, such as an outboard motor, may also be used.
