る等の不都合がある。
In a motorcycle, various heavy objects such as an engine, a fuel tank, and a battery are attached to the body of the motorcycle. These parts are placed in a well-balanced manner on the left and right so that the center of gravity is on the center line of the car body, but in the case of a shaft-drive car where the rear wheels, engine, and drive shaft are connected and driven, simply arranging the parts is not sufficient. It is difficult to maintain the weight balance between the left and right sides, and the center of gravity may deviate from the center line of the vehicle if there is a heavy object. In such a case, if you take your hands off the steering wheel and drive the vehicle, the front wheels will cut toward the side where the center of gravity is, resulting in poor straight-line running stability and other inconveniences.
この発明は、かかる点に鑑み重心位置が車体の
中心線に対して左右にずれている場合においても
直進走行安定性を有するオートバイの車体を得る
ことを目的とする。
In view of this, an object of the present invention is to provide a motorcycle body that maintains straight-line running stability even when the center of gravity is deviated from the left or right with respect to the center line of the vehicle body.
以下本発明を図面に示す実施例について説明す
る。
The present invention will be described below with reference to embodiments shown in the drawings.
オートバイの車体１は、鋼管を適宜溶着して作
ることが多く、車体１の中心線はＡである。これ
に対し、エンジン２、後輪３等、各種部品を装着
してゆくと、車全体の重心Ｂは、車体１の中心線
Ａ上から外れた位置になる。このような場合に、
車体１の前端に溶着して固着されるヘツドパイプ
４を、後輪３の中心と重心Ｂを結んだ重心線Ｃ上
にオフセツトして、車体１に固着する。ヘツドパ
イプ４は、前輪５を装着した前ホークを回動自在
に連結するもので、前輪５の中心も重心線Ｃを通
る。 The body 1 of a motorcycle is often made by appropriately welding steel pipes, and the center line of the body 1 is A. On the other hand, as various parts such as the engine 2 and the rear wheels 3 are installed, the center of gravity B of the entire vehicle moves away from the center line A of the vehicle body 1. In such a case,
A head pipe 4 which is welded and fixed to the front end of the vehicle body 1 is fixed to the vehicle body 1 by being offset on the center of gravity line C connecting the center of the rear wheel 3 and the center of gravity B. The head pipe 4 rotatably connects the front fork on which the front wheel 5 is attached, and the center of the front wheel 5 also passes through the center of gravity line C.
しかして、車体１の前端のヘツドパイプ４を重
心線Ｃ上に位置するようにオフセツトさせて車体
１に固着することによつて、前輪５と後輪３が重
心線Ｃ上に配置できて、車の重心Ｂが、前輪５と
後輪３を結んだ線上になり、車体１に関係なく、
左右のバランスがとれる。このため、直進走行安
定性の向上が図れる。又、ヘツドパイプ４を僅か
にオフセツトするだけでよいので、製作上他に与
える影響が少く、ハンドル操作等も気づかずに自
然にできる範囲で処理できる。 By offsetting the head pipe 4 at the front end of the vehicle body 1 so that it is located on the center of gravity line C and fixing it to the vehicle body 1, the front wheels 5 and rear wheels 3 can be placed on the center of gravity line C, and the vehicle The center of gravity B is on the line connecting the front wheels 5 and rear wheels 3, regardless of the vehicle body 1,
Balance between left and right. Therefore, straight-line running stability can be improved. In addition, since it is only necessary to slightly offset the head pipe 4, there is little influence on other parts of the manufacturing process, and the steering wheel operation can be done within a natural range without noticing.
以上説明したように、この発明は、重心位置が
車体の中心線に対して左右に外れるオートバイに

ンスが合致し、直進走行安定性の向上が図れる。
又、ヘツドパイプだけオフセツトして車体前端に
固着するだけでよいので、車体製作等、他に与え

に気づくこともなく、自然に操作できる範囲で処
理できる。
As explained above, the present invention provides for a motorcycle in which the center of gravity is offset to the left or right with respect to the center line of the vehicle body. Since the center of gravity is placed on the line connecting the centers of the front and rear wheels, the left and right balance of the entire vehicle is matched, improving straight-line driving stability.
Further, since it is only necessary to offset the head pipe and fix it to the front end of the vehicle body, there is little influence on other processes such as the production of the vehicle body, and productivity is high. In addition, since the amount of offset is small, the driver does not notice it when operating the steering wheel, and can handle it within a natural range.
