本発明は車体の前部に１輪の操向輪、後部に左右１対の
駆動輪を備えた自動３輪車に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a three-wheeled motor vehicle having one steering wheel at the front of the vehicle body and a pair of left and right driving wheels at the rear.
この種の自動３輪車は、主として砂地岬の不整地はもち
ろん、湿地帯等の比較的水深の深い場所を走行する特殊
性から、バルーンタイヤと称される浮力を備えた低圧極
太のタイヤが装備されている。ところで、上記湿地帯で
の使用においては、水深が深すぎて走行不能な場所があ

水面上を走行可能な場所まで移動させたｂという要求が
ある。したがってこの自動３輪車では、人が乗らない空
車の状態において、３輪の輪荷重を略均等にして水面に
浮かせた時の安定性を確保する必要がある。This type of three-wheeled motor vehicle mainly uses low-pressure, extra-thick tires with buoyancy called balloon tires because of the special nature of driving on uneven terrain such as sandy capes, as well as relatively deep water areas such as wetlands. Equipped. By the way, when using the above-mentioned wetlands, there are places where the water is too deep and it is impossible to drive, so it is necessary to float the troops on the water surface and drag them by boat etc.
There is a request for b to be moved to a place where it can run on the water surface. Therefore, in this three-wheeled motor vehicle, it is necessary to ensure stability when floating on the water surface by substantially equalizing the wheel loads on the three wheels when the vehicle is empty and no one is riding on it.
本発明はこのよう、な事情にもとづいてなされたもので

３輪車を提供しようとするものである。The present invention was made based on the above circumstances, and its purpose is to ensure that the wheel loads on the three wheels, the steering wheel and the driving wheel, are approximately equal when the nine cars are busy with no passengers on board. Another object of the present invention is to provide a three-wheeled motor vehicle that has significantly improved stability, especially when floating on the water surface.

ある。That is, in order to achieve the above object, the present invention moves the center of gravity of the engine, which is the heaviest among the functional parts constituting a three-wheeled motor vehicle, from the steering wheel to the wheel pace by 55 degrees.
It is characterized by being located within a range of ~75 arcs.
以下本発明を図面に示す一実施例にもとづいて説明する

較的後方に位置されている。An engine 9 is mounted on the vehicle body 1 so as to be located between the steering wheels 3 and the drive wheels 6.6. The engine 9 on the flow side is an air-cooled two-stroke single-cylinder engine, and is equipped with a cylinder block 11 and a cylinder head 12 on the upper surface of the front end of a crankcase 10. The engine 9fi is one in which the center G is located at or near the crankshaft 13, and this center of gravity is located at the steering wheel s. It is mounted on the vehicle body 1 so as to be located within a range of 75%. death'
As a result, the single center G of Ennon 9 is placed in the above Ili circle, so that the center of gravity of the entire three-wheeled automatic army is located at the approximate center of gravity of the triangle formed by the steering wheel 3 and the driving wheel 6.6. Empirical Kl to come to be located! It is proved. Therefore, when this three-wheeled motor vehicle is viewed from the side, the drive wheel 6. #Glue is located relatively backward.

According to this configuration, the engine 9, which is the heaviest among the various functional parts that make up the three-wheeled vehicle, is covered by the cover 16. The overall center of gravity of the three-wheeled motor vehicle is determined by the steering wheels so that the center of gravity of the three-wheeled vehicle is located within the range of 5 doors 5 of the wheel pace L as measured from the steering wheel 3. 3 and the drive wheel 6.6 or near the centroid of the triangle.

。The present invention described in detail above is applicable to a three-wheeled motor vehicle in which an engine is disposed between one steering wheel and two driving wheels, and the engine has a center of gravity at or near the crankshaft. The center of gravity of this engine is located within the range of 55 to 75 degrees of wheel pace from the steering wheels. According to this, the center of gravity of the three-wheeled vehicle is determined by the centroid of the triangle formed by the steering wheels and the driving wheels, taking into account the weight of various other functional parts and members that make up the three-wheeled vehicle. It has been empirically proven that the steering wheel and drive wheel are located at or near the steering wheel when the vehicle is empty and the driver is not on board. The wheel load on the driving wheels becomes approximately equal. Therefore, it looks like this tricycle is floating on the water! Even in this case, the entire structure does not tilt and has excellent effects such as improved stability.
