本発明は、側車付二輪車に関し、特にその車体
ジオメトリーに特徴を有した側車付二輪車に関す
る。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a two-wheeled vehicle with a sidecar, and more particularly to a two-wheeled vehicle with a sidecar having characteristics in its body geometry.
［従来の技術］
従来の比較的軽量（例えば排気量1000c.c.以下の
もの）の側車付二輪車にあつては、本機二輪車の
前後輪及び側車の側輪は路面に対して垂直に接地
するようなジオメトリーが採られていた。[Prior art] In the case of conventional relatively lightweight two-wheeled vehicles (for example, those with a displacement of 1000 c.c. or less) with sidecars, the front and rear wheels of the two-wheeled vehicle and the side wheels of the sidecar are perpendicular to the road surface. The geometry was such that it would touch the ground.
しかしながら、従来に比べ本機二輪車が大重量
（例えば排気量1000c.c.を越えるもの）の側車付二
輪車を提供する場合、上記従来のジオメトリーを
そのまま適用したのでは、本機二輪車と側車との
重量アンバランスの増大等により、以下のような
問題が発生する。 However, when providing a motorcycle with a sidecar that is heavier than conventional motorcycles (for example, one with a displacement exceeding 1000 c.c.), applying the conventional geometry as described above will not allow the two-wheeler and sidecar to The following problems occur due to an increase in weight imbalance between the two.
すなわち、本機二輪車の重量が側車のそれに比
べて大きくなればなる程、側車側へ旋回する際の
本機二輪車に発生する遠心力は大きくなり、よつ
て、側車の浮き上がり現象が生じ易くなる。この
点は、側車の乗員有無に拘らず通常の自動二輪車
同様の特性を確保できるように対処しなければな
らない。 In other words, the greater the weight of the two-wheeled vehicle compared to the sidecar, the greater the centrifugal force generated in the two-wheeled vehicle when turning toward the sidecar, which causes the sidecar to lift up. It becomes easier. This point must be addressed in such a way that the characteristics of a normal motorcycle can be ensured regardless of whether or not there are occupants in the sidecar.
［発明が解決しようとする課題］
上記のような問題点に鑑み、本願発明の目的と
するところは、本機二輪車の重量が比較的大きな
側車付二輪車であつても、従来の側車付二輪車あ

できるようなジオメトリーを採用した側車付二輪
車を提供することにある。[Problems to be Solved by the Invention] In view of the above-mentioned problems, it is an object of the present invention to solve the problem that even if the two-wheeled vehicle is a relatively heavy two-wheeled vehicle with a sidewheel, An object of the present invention is to provide a two-wheeled vehicle with a side wheel that adopts a geometry that can ensure running characteristics similar to those of a two-wheeled vehicle or a normal two-wheeled motor vehicle.
［課題を解決するための手段］
本発明による側車付二輪車は、本機側の車輪と
側車側の車輪の夫々の車軸をその外側端が高くな
るように傾斜させ、且つ前記側車側の車輪の車軸
を、その車両左右方向における外側端部が内側端
部よりも車両の前方側に位置するように傾斜させ
ると共に該側車側の車輪の車軸を本機後車輪の車
軸に対し本機前車輪側へ偏位した位置に設けたこ
とを特徴としている。[Means for Solving the Problems] A two-wheeled vehicle with a sidecar according to the present invention has the axles of the wheels on the machine side and the wheels on the sidecar side inclined such that their outer ends are higher, and Tilt the axle of the side wheel so that its outer end in the left-right direction of the vehicle is located further forward of the vehicle than the inner end, and align the axle of the side vehicle side wheel with respect to the axle of the rear wheel of the machine. It is characterized by being installed in a position offset toward the front wheels.
［作用］
第１に、本機側の車輪の車軸をその外側端が高
くなるように傾斜、すなわち、本機側の車輪に逆
キヤンバを設けたことにより、本機二輪車の重心
が予め側車側へ偏倚した状態となることから、側
車側へ旋回する際の側車の浮き上がり現象を防止
することができる。[Function] First, by tilting the axle of the wheel on the side of the machine so that its outer end is higher, in other words, by providing a reverse camber on the wheel on the side of the machine, the center of gravity of the two-wheeled vehicle of this machine is aligned in advance with the side wheel. Since the vehicle is biased to the side, it is possible to prevent the side vehicle from lifting when turning toward the side vehicle.
第２に、側車側の車輪の車軸をその外側端が高
くなるように傾斜させると共に、かかる車軸を車
両中心面に対して前方に傾斜、すなわち、側車側
の車輪に逆キヤンバを設けると共にトーインを付
与せしめたことにより、車両の直進性を確保する
ことができる。 Second, the axle of the wheel on the side car is tilted so that its outer end is higher, and the axle is tilted forward with respect to the vehicle center plane, that is, the wheel on the side car is provided with a reverse camber. By providing toe-in, the straight-line performance of the vehicle can be ensured.
詳述すると、前述の如く側車の浮き上がり防止
対策として本機側の車輪に逆キヤンバを設けたこ
とにより、前後の車輪各々にキヤンバスラストが
生じ、車両は常に側車側へ旋回する傾向を持つこ
とになる。従つて、このままでは車両の直進性が
確保されない為、側車側の車輪にも逆キヤンバを
設けて本機側に生じるキヤンバスラストを打ち消
すようにする。しかしながら、本機側は前後二つ
の車輪にキヤンバスラストが生じるのに対し、側
車側は一つの車輪にキヤンバスラストが生じるだ
けである為釣り合いがとれず、依然として本機側
にキヤンバスラストが発生した状態となる。 To explain in detail, as mentioned above, as a countermeasure to prevent the sidecar from lifting up, the wheels on the machine side are provided with reverse camber thrust, which creates canvas thrust in each of the front and rear wheels, which prevents the vehicle from always turning toward the sidecar. I will have it. Therefore, since the straight running performance of the vehicle cannot be ensured as it is, a reverse camber is also provided on the wheels on the side car side to cancel out the camber thrust that occurs on the main machine side. However, while canvas thrust occurs on the two front and rear wheels on the machine side, canvas thrust only occurs on one wheel on the sidecar side, so there is no balance, and canvas thrust still occurs on the machine side. occurs.
そこで、さらに側車側の車輪にトーインを施す
ことによつて、側車側の車輪の逆キヤンバだけで
は打ち消せなかつた本機側のキヤンバスラストを
完全に消去し、これにより車両の直進性が確保さ
れることになる。 Therefore, by applying toe-in to the wheels on the sidecar side, the canvas thrust on the machine side, which could not be canceled out by the reverse camber of the wheels on the sidecar side, is completely eliminated, and this improves the straightness of the vehicle. will be ensured.
第３に、側車側の車両の車軸を本機後車輪の車
軸に対し本機前車輪側へ偏位した位置に設ける。
すなわち、十分なリード量を確保することによ
り、本機二輪車側への旋回時における車両の前の
めり現象を防止することができる。 Thirdly, the axle of the vehicle on the side car side is set at a position offset toward the front wheels of the machine with respect to the axles of the rear wheels of the machine.
That is, by ensuring a sufficient amount of lead, it is possible to prevent the vehicle from leaning forward when the vehicle turns toward the two-wheeled vehicle.
詳述すると、従来のようなキヤンバ角を有しな
い車両にあつては、本機側へ旋回する際、本機車
輪には旋回側へキヤンバスラストが生じ易い傾向
にあり問題はないが、前述の如く本機車輪に逆キ

じ易い傾向になり（ハンドルを右側へ向けると、
逆キヤンバとなつていることから、前輪は車両前
方へ傾斜した状態となる）、車両のいわゆる前の
めり現象（側車の前方部分が落ち込む現象）が生
じる。 To be more specific, when a vehicle does not have a conventional camber angle, when turning toward the main machine, the main machine's wheels tend to generate canvas thrust toward the turning side, and there is no problem. If you turn toward the machine with the wheels of this machine equipped with a reverse camber as shown in the figure, the wheels of this machine tend to generate canvas thrust in the forward direction of the vehicle (if you turn the steering wheel to the right,
Because of the inverted camber, the front wheels are tilted toward the front of the vehicle), resulting in the so-called forward leaning phenomenon of the vehicle (a phenomenon in which the front portion of the side wheels dips).
そこで、これに対処すべく側車側の車輪を車両
前方側に配置して本機後輪に対するリード量を大
きくし、すなわち、路面に対する車両の支点を前
方に位置付けてかかる前のめり現象を防止してい
る。 Therefore, in order to deal with this, the wheels of the side car are placed on the front side of the vehicle to increase the amount of lead from the rear wheels of this machine.In other words, the fulcrum of the vehicle relative to the road surface is positioned forward to prevent this phenomenon of leaning forward. There is.

わゆるキヤンバスラストが作用する。[Examples] Examples of the present invention will be described below with reference to the drawings. 1 to 3 show a two-wheeled vehicle with a side wheel, which is an embodiment of the present invention. In the figure, 1 is the motorcycle main unit, and 2 is the side vehicle. These main machine 1 and sidecar 2 are
As shown in Fig. 4, the machine side frame F 1 and the side car side frame F 2 are assembled as the respective skeletons, but the connecting frame F 3 is bent to connect the frames F 1 and F 2 . It has been processed,
The frame F 1 and the frame F 2 are assembled in advance so as to open downward from each other. Therefore, as shown in FIG. 1, the wheels 1a on the machine 1 side and the wheels 2a on the side car 2 side are set so as to open downward when viewed from the front. In other words, with respect to the vertical line V, the outer end of the axle of each wheel is at a higher position than the inner end, i.e., the vertical diameter extension lines Y 1 , Y 2
are inclined inward by angles θ 1 and θ 2 . By setting such angles θ 1 and θ 2 , so-called canvas thrust acts on the vehicle body.

現象を助長することになる。 In this case, canvas thrust will act on the front wheels 1a and rear wheels 1b on the machine side, and only on one wheel 2a on the side car side, so that they face each other, but in terms of balance, the machine side The canvas thrust becomes large. Therefore, in order to deal with this unbalanced cabin thrust, as shown in FIG. The unbalanced canvas thrust can be completely eliminated by providing a so-called toe-in angle in which the extension line X of the vertical diameter of the wheel 2a is tilted forward by an angle θ 3 . to erase. By setting such a camber angle and toe-in angle, the canvas thrust acting on the side wheel 2 side is eliminated, but conversely, when turning toward the machine 1 side, it is possible to eliminate the canvas thrust acting on the side wheel 2 side. This is particularly disadvantageous for sidecars leaning forward. Furthermore, if there is an occupant in the sidecar, the centrifugal force acting on the occupant will promote the forward leaning phenomenon.

b and the axle misalignment of the wheel 2a of the sidecar 2, the so-called lead amount lm/m, is increased, for example l = 260~
This problem can be solved by setting the speed to about 300m/m.
すなわち、本機１側への旋回時に生じる前のめ
