Description
この発明は自動二輪車の雨、雪、強風等の悪状況下での走行安定装置に関する。 The present invention relates to a travel stabilization device for motorcycles under bad conditions such as rain, snow, and strong winds.
特許第３０２７２６５号における重量物付加による走行安定装置。 The traveling stabilizer by adding heavy objects in Japanese Patent No. 3027265.
カーブ走行時の遠心力、横風、路面の凹凸等でサイドカーの側車輪が浮き上がった場合、操縦者はスピードを緩めたり、回転半径を大きくして側車輪を着地させようとするが、付加質量により慣性が大きい為ただちに接地しないで不安定になる。 If the side wheel of the sidecar is lifted due to centrifugal force, crosswind, or road surface unevenness when driving on a curve, the pilot tries to slow down the speed or increase the turning radius to land the side wheel. Because of the large inertia, it becomes unstable without immediately touching the ground.
また浮き上がった側車輪はトーイン効果が無くなる為、車体の走行方向が側車輪寄りに変わり不安定になる。 Further, since the lifted side wheel loses the toe-in effect, the traveling direction of the vehicle body changes toward the side wheel and becomes unstable.
また向い風で走行する時や高速で走行する時は前輪分担荷重が減少するので不安定になる。 Also, when driving in a headwind or at a high speed, the load sharing on the front wheels decreases, which makes it unstable.
請求項１記載の発明について、水平翼は走行時に常に下向きの揚力を速度に自乗比例して発生し、その揚力の作用点は搭乗時の自動二輪車の重心位置の前方にあるので、水平翼に最も近い補助輪のみならず、前輪もタイヤの接地圧を増加させて走行を安定させる。The invention of claim 1, wherein, since the horizontal wing squared proportional to generate always a downward lift the speed during running, the action point of the lift in front of the center of gravity of the motorcycle during boarding, the horizontal wing Not only the nearest auxiliary wheel but also the front wheel increases the ground pressure of the tire to stabilize the running.
また補助輪のタイヤが浮き上がっても慣性質量が小さいのでただちに着地できる。 Even if the auxiliary wheels are lifted, the inertial mass is so small that they can land immediately.
またフラップを作動させてより大きな揚力を得ることができるので追い風による揚力減少に対応できる。 Further, since the flap can be operated to obtain a higher lift, it is possible to cope with a decrease in lift due to the tailwind.
また重量級の自動二輪車に対しては水平翼を複葉とすることで十分な効果を得ることができる。 For heavy-duty motorcycles, a sufficient effect can be obtained by using double blades for the horizontal wing.
垂直翼は高速時の直進性維持の為に必要なものである。 The vertical wing is necessary to maintain straightness at high speed.
補助輪のタイヤのトーインによる直進性維持の効果は接地圧に左右されるので路面状況等によって変動するが、特に高速時には連結部材、水平翼、補助輪、垂直翼によって構成された装置全体が受ける空気抵抗が増大し、自動二輪車の進行方向を補助輪側に曲げようとするモーメントが増大する。The effect of maintaining straightness due to toe-in of the auxiliary wheels depends on the contact pressure and varies depending on the road surface conditions, etc., but especially at high speeds , the entire device composed of connecting members, horizontal wings, auxiliary wheels, and vertical wings receives The air resistance increases, and the moment for bending the traveling direction of the motorcycle toward the auxiliary wheel increases.
搭乗時の自動二輪車の重心位置よりも前方に設置した垂直翼が発生する車体側方向の揚力は、車体側に進行方向を曲げようとするモーメントを発生するので［００１１］で説明したモーメントを打ち消しあうので自動二輪車の直進性を維持できる。 The lift in the vehicle body direction generated by the vertical wings installed in front of the center of gravity of the motorcycle at the time of boarding generates a moment to bend the traveling direction toward the vehicle body, so the moment described in [0011] is canceled out. As a result, the straightness of the motorcycle can be maintained.
以上に説明したように本発明の補助輪による自動二輪車の走行安定装置は、連結部材と水平翼と垂直翼と補助輪を備え、水平翼は補助輪のタイヤの接地圧を確保し、垂直翼は補助輪のトーイン効果と併せて左右非対称の車体を低速時、高速時共に直進性を確保して自動二輪車の走行を安定させる。As described above, the motorcycle travel stabilization device according to the present invention includes a connecting member, a horizontal wing, a vertical wing, and an auxiliary wheel. The horizontal wing secures the contact pressure of the tire of the auxiliary wheel, and the vertical wing In addition to the toe-in effect of the auxiliary wheels, the left and right asymmetrical body is kept straight at both low and high speeds to stabilize the motorcycle.
似たような構成であるサイドカーは車重が重いのでハンドル操作を軽くする為、側車輪を重心位置よりも後方の左右の片側に設置するので下り坂での急制動時に前方へ転倒する危険がある。A sidecar with a similar configuration is heavy and has a heavy vehicle weight, so the side wheels are placed on the left and right sides behind the center of gravity, so there is a risk of falling forward during sudden braking on a downhill. is there.
本発明は補助輪を搭乗しない時の自動二輪車の重心位置の左右の片側に設置するので搭乗時には重心が後方に移動する為、［００１４］で説明した危険性はない。Since the present invention is installed on the left and right sides of the position of the center of gravity of the motorcycle when the auxiliary wheel is not mounted, the center of gravity moves rearward when boarding, so there is no risk described in [0014].
