Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a motorcycle that can run not only on land but also on water and snow.

[Conventional technology]

As this type of motorcycle, for example, JP-A-53-75
619 and Japanese Patent Laid-Open No. 54-113186, the former has floats installed on both sides of the motorcycle, and floats are used to float the motorcycle on the water.
Propulsion is obtained from web propellers installed on both sides of the rear wheels, and on snow the lower surface of the float is used as a sliding surface to propel the vehicle forward using the driving force of the rear wheels. It moves by rotating the floats installed at both ends.

[Problem that the invention seeks to solve]

However, in all of the above, the water and snow traveling devices are large and the propulsive force and driving force are weak, so they are unsuitable for motorcycles that require agile running performance.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a multi-purpose motorcycle that has sufficient propulsive force and driving force, and that allows easy installation of attachments and ensures good running performance.

[Means for solving problems]

To achieve the above object, the present invention provides an engine unit mounted on a vehicle body frame, a waterproof cover covering the engine unit, a front fork supporting the front wheels, and a power transmission device transmitting power from the engine unit to the rear wheels. , a propulsion device for traveling on water that is switched and driven by this power transmission device, a float that is removably installed on the vehicle body frame, a ski that is attached to the front fork in place of the front wheel when driving on snow, and a ski that is attached to the front fork in place of the front wheel when driving on snow, and a ski that is attached to the front fork in place of the front wheel when driving on snow It is characterized by having an endless track device connected to a power transmission device.

〔Example〕

Hereinafter, one embodiment of the present invention will be described based on the drawings.

The motorcycle 1 has an engine unit 3 mounted in the center of a body frame 2, and the engine unit 3 is covered with a waterproof cover 4. A front fork 6 supporting a front wheel 5 and a front fork 6 for supporting a front wheel 5 are mounted on the front part of the body frame 2. A bar handle 7 for steering the rear wheel 8 is provided at the rear of the body frame, and a rear fork 9 that supports the rear wheel 8 and a suspension suspension 1o are provided at the rear of the body frame.
A fuel tank 11 and a seat 12 are provided on the upper part of the vehicle body frame 2.

In one arm 9a of the rear fork 9, a drive shut 1 is connected to a rod 14 of a transmission 13 of the engine unit 3 via a universal joint 15.
6 is inserted and connected to the rear wheel 8 to constitute a power transmission device 17, and the power of the engine unit 3 is transmitted by this power transmission device 17 when traveling on land or on snow, which will be described later.

Further, the transmission 13 of the engine unit 3 is provided with a propulsion device 18 for traveling on water, and is used in conjunction with the power transmission device 17 when traveling on water. This propulsion device 18
The rotor 19 of the mission 13 rotates an impeller (not shown) to eject a jet of water rearward from the outlet 20, 20 to generate propulsive force.

Furthermore, floats 21 and 22 are attached to the motorcycle 1 to float the motorcycle 1 when traveling on water.

These floats 21 and 22 are made of FRP and are formed into a closed box shape, and the float 21 attached to the front of the vehicle body is
The float 22 is attached to the front part of the vehicle body frame 2 via a stay 23 above the front wheel 5, and the float 22 is attached above the rear wheel 8 of the vehicle body frame 2, and can be removed when driving on land or on snow. .

Furthermore, in this motorcycle 1, skis 24 are attached to the front fork 6 instead of the front wheel 5 when driving on snow, and a track device 25 is attached to the rear fork 9 instead of the rear wheel 8, and a power transmission device 17.

Since the motorcycle 1 according to the present invention is configured as described above, when traveling on land, it travels in the same manner as a normal motorcycle in the state shown in FIG. 1, and when traveling on water, it travels in the state shown in FIG. 4. As shown in FIG. 5, the floats 21 and 22 are attached and the vehicle travels using the propulsion device 18 for traveling on water, and when traveling on snow, it travels using skis 24 and an endless rolling device 25, as shown in FIG.

Therefore, compared to conventional floats when traveling on water, skis when traveling on snow, and endless rolling devices are smaller and easier to install, and the propulsive force of water propulsion devices and the driving force of endless rolling devices are also smaller than before. Since it is also powerful, it can be made into a multi-purpose motorcycle that ensures good running performance.

Furthermore, the water propulsion device used in water scooters and the endless rolling device used in snowmobiles can be used, respectively, which is advantageous in terms of cost.

〔Effect of the invention〕

As described above, the present invention provides a propulsion device for traveling on water in the engine unit of a motorcycle, and a float is removably disposed on the body frame to enable traveling on water, and when traveling on snow, skis are used in place of the front wheel. Since the endless rolling device is driven by the engine unit instead of the rear wheel, it is possible to provide a multi-purpose motorcycle that has sufficient propulsive force and driving force, is easy to install attachments, and has good running performance. can.
