Abstract

PURPOSE:To obtain a light-weight amphibian vehicle having a simple structure at a low cost in a vehicle mounting a land driving source by installing a propelling device for surface navigation which is driven by the land driving source. CONSTITUTION:In an amphibian vehicle 1, floats 3L, 3R are provided on both left/right sides of a vehicle body 2, e.g., a saddle straddling type four-wheel vehicle while providing a surface navigating propelling device 4 in the rear on the bottom portion of the vehicle body 2. At the time of navigating on water surface, the driving force of an engine 5 as a land traveling driving source which is mounted on the vehicle body 2 is transmitted to the propelling device 4 via power transmission means 6, 9, 8 and a gear box 7. An unshown impeller which is housed inside the main duct body 4a in the propelling device 4 is rotated to generate a water current and obtain propulsion force. Also a rudder duct 4e which is pivotally supported in the rear of the body 4a is oscillated in left/right directions by means of a control handle 2a to carry out change- direction.

Description

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

[Conventional technology]

One type of special vehicle is an amphibious vehicle, which is equipped with a propulsion device for navigation on water as well as various mechanisms for traveling, and is capable of traveling not only on land but also on water.

[Problem to be solved by the invention]

Incidentally, such an amphibious vehicle is normally configured to drive the land traveling mechanism and the propulsion device for water navigation by separate engines. This not only complicates the work required to perform maintenance and inspection on a plurality of engines, but also increases vehicle weight and manufacturing costs.

SUMMARY OF THE INVENTION In view of the above circumstances, an object of the present invention is to provide an amphibious vehicle that facilitates maintenance and inspection work, reduces vehicle weight, and reduces manufacturing costs.

[Means to solve the problem]

Therefore, in the present invention, the above object has been achieved by configuring the propulsion device for water navigation to be driven by a drive source for land travel.

[Effect]

The R side for land travel and the propulsion device for water navigation are driven by one drive source.

〔Example〕

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

FIG. 1 shows an amphibious vehicle configured by providing a straddle-type four-wheeled vehicle with a float and a propulsion device for water navigation.
This shows an example to which the present invention is applied.

This amphibious vehicle 1 has floats 31° 3R installed in the left and right side areas of a vehicle body (saddle-type four-wheeled vehicle) 2, and a water navigation propulsion device 4 installed at the rear of the bottom of the vehicle body 2. It is made up of.

As shown in FIG. 1.2, an engine 5 as a drive source for land travel mounted on the vehicle body 2 is provided with a drive sprocket 6 at the end of a drive shaft 5a. On the other hand, the gear box 7 provided at the rear of the engine 5 is provided with a driven sprocket 8 at the end of its input shaft 7a, and a chain 9 is wound around the drive sprocket 6 and the driven sprocket 8. It is hung.

The gear box 7 has the input shaft 7a and an output shaft 7 extending in the longitudinal direction of the vehicle body orthogonal to the input shaft 7a.

A bevel gear 7C1 and a bevel gear 7d that fit into each other are fixedly installed on the input shaft 7a and the output shaft 7b, respectively, and the input shaft 7a, the output shaft 7b, and the bevel gears 7c and 7d are installed in the casing 7e. Accommodation has been set up.

A propulsion device 4 is provided behind the gear box 7. This propulsion device 4 includes a main duct body 4a fixed to the gear box 7, and an impeller 4b housed in the body 4a and fixed to the output shaft 7b of the gear box 7. . The above body 4a
An inlet 4C is formed at the front lower part of the body 4a, and an ejection port 4d is formed at the rear of the body 4a.Furthermore, a ladder duct 4e is connected to the rear of the body 4a via a support shaft 4f. As shown by the arrow mark and the arrow R, it is supported so as to be swingable in the left and right directions.

The ladder duct 4e is linked to the steering handle 2a of the vehicle body 2 by a linking means (not shown), and is swung left and right in conjunction with the operation of the handle 2a.

Now, when the engine 5 starts operating, the wheels of the vehicle body 2 are rotationally driven via a power transmission mechanism (not shown), and the vehicle 1 runs on land.

Meanwhile, the engine 5 starts operating and the drive shaft 5
When a is driven to rotate, the input shaft 7a is rotated via the drive sprocket 6, chain 9, and driven sprocket 8, and then the impeller 4b is rotated via the bevel gears 7c, 7d and the output shaft 7b. Vehicle 1
When is on the water, due to the rotation of the impeller 4b,
Water is sucked in from the suction port 4C of the main duct body 4a, and then the sucked water is spouted rearward from the spout port 4d through the rudder duct 4e, thereby allowing the vehicle 1 to sail on water. Note that the direction of the vehicle 1 on the water is changed by swinging the rudder duct 4e.

As described above, the vehicle 1 uses one engine 5 to travel on land and on water.

By the way, the engine 5 in the vehicle 1 is equipped with a reverse mechanism (not shown), and the drive shaft 5a can be reversely rotated by the mechanism. When the drive shaft 5a is reversely rotated, the impeller 4b of the propulsion device 4 is reversely rotated, water is ejected forward from the intake port 4C of the main duct body 4a, and the vehicle 1 moves backward on the water.

In the vehicle 1, the propulsion device 4 is always driven when the engine 5 is in operation, but the drive shaft 5a
A clutch mechanism is interposed between the and propulsion device 4, and the clutch mechanism is turned off except when navigating on water and the propulsion bag! 4 can also be configured to be stopped. Furthermore, it goes without saying that the present invention can be effectively applied not only to amphibious vehicles comprising a saddle-ride type vehicle equipped with a float and a propulsion device, but also to various B-type amphibious vehicles.

〔Effect of the invention〕

As described above in detail, according to the amphibious vehicle according to the present invention, by driving the propulsion device for water navigation by the drive source for land travel, it is possible to travel on land and navigate on water with one drive source. Therefore, US work is easy and 3.
Moreover, the weight of the vehicle can be reduced, and manufacturing costs can also be reduced.
