In order to solve the above-mentioned problem, in this patent, it is attached to a steering device located in front of an electric motorcycle equipped with a tire for running on a snow surface , and in the plan view, the front side is a large semicircle and the rear side is a small semicircle. A snow surface is formed on the lower surface of the curved plate that is curved narrowly in a side view and curved forward in a side view, and the front semicircle center and the rear semicircle of the curved plate. The snow surface portion in the range between the centers has a cross-sectional shape when viewed from the front , the left and right end portions exhibit downwardly sharp edges, the inside of the edge is slightly convexly curved, and the subsequent central portion is more than the edge. It is formed in a corrugated shape that forms a trough that is located downward and convexly convex downward, and the portion that forms the corrugated shape has a height from the bottom of the curved plate at the center of the trough in a side view, Gradually increase from the front to the center The valley is formed to have an elliptical shape having a long axis in the front-rear direction in plan view, and the valley center in the front cross-sectional view. In addition, it is preferable to provide a snowboard-like downhill body characterized by having longitudinal grooves in the front-rear direction dug in a U-shape .
Moreover, it is preferable to use a snowboard-like downhill body characterized by having small and slender edges on the left and right of the longitudinal groove portion.


従来小型雪上車における、山林での雪道での走行は車重があり車体が長く、回転半径も大きく、木への衝突、深い雪の溝等に埋もれ脱出困難な状況が、多く発生した、其れに引き換え本発明では、後部に設けた極太で深い溝は元より薄くて丈夫で軽いタイヤ車輪の効果を発揮して、今回の発明の主幹である前方に設けた操舵装置のスノーボード状滑降体の働きと、特に低速域にての駆動力を発揮出来る変速比を有し、バイク形状である為に、小回りが効き車重が軽量のために、深い雪の溝に嵌まっても運転者の力を加えての脱出を容易とし、また平坦な圧雪面においては、スノーボード状滑降体の働きで、2輪車の如く軽いハンドルさばきをもって転到しにくい走行に適している。   In conventional small snow vehicles, traveling on snowy roads in mountain forests has a lot of weight, a long car body, a large turning radius, many situations where it is difficult to escape due to collision with trees, deep snow grooves, etc. In exchange for that, in the present invention, the extremely thick and deep groove provided in the rear part exhibits the effect of a tire wheel that is thinner, stronger and lighter than the original, and the snowboard-like downhill of the steering device provided in front of which is the main trunk of the present invention It has a gear ratio that can demonstrate the power of the body and the driving force especially in the low speed range, and because it is a motorcycle shape, the small turn is effective and the weight of the vehicle is light, so even if it fits in a deep snow groove It is easy to escape by applying a person's force, and on a flat snow-capped surface, it is suitable for traveling that is difficult to reach with a light steering wheel like a two-wheeled vehicle due to the action of a snowboard-like downhill body.

本発明の電動雪上バイク37用のスノーボード状滑降体8は図1、図2、図3、図4、図5に示される様に、電動雪上バイク37の操舵機能を充分に発揮する為に設ける事により実現可能とした。   As shown in FIGS. 1, 2, 3, 4, and 5, the snowboard-like downhill body 8 for the electric snow bike 37 according to the present invention is provided to fully exhibit the steering function of the electric snow bike 37. It became feasible by things.

スノーボード状滑降体8の形態と機能において、電動雪上バイク37のバイク用操舵装置10の前方下部には、前側は大きい半円Gと後側は小さい半円H形状でF部より前後の面半円部分にはエッジが無く、中央部分がFとF2の間の狭く絞られた部分にはサイドカーブエッジCを設けた平面形状を成し、中央裏面部分は前後方向に緩やかな楕円面形状を呈し、縦溝Bをコノ字状に掘った、滑降面Aが、前記サイドカーブエッジC部分より、若干低位置に形成されると共に、前部は大きく後部は小さく反り上がっており其の部分のエッジは前記の如くエッジLの角の部分は丸く仕上げられており、反り上がりの裏面部Jは平面に仕上がって成る、スノーボード状滑降体8を設けると共に、前項電動バイク37の直進時にはハンドルを左右小刻みに揺動させることにより、2輪車の如く、前記の縦溝Bの効果も加わり、安定した直進走行が可能となり、更に又、前記の反り上がった半円部G、Hのエッジ部分は丸く仕上げられていてエッジが無い為に、電動バイクの傾き具合による左右のターン時にはG、Hの部分が雪面に、左右のサイドカーブエッジCよりも先に雪面に食い込んでターンの妨げになるのを防止することにより左右のサイドカーブエッジCだけの効果が発揮されて鋭いターンを可能としているのが今回の発明の根幹である。   In the form and function of the snowboard-like downhill body 8, the front half of the motorcycle steering device 10 of the electric snow bike 37 has a large semicircle G on the front side and a small semicircle H on the rear side, and a surface half before and after the F part. The circular part has no edge, the central part has a flat shape with a side curve edge C in the narrowed part between F and F2, and the central back part has a gentle elliptical shape in the front-rear direction. The downhill surface A, which is formed in the shape of a conical shape, is formed at a slightly lower position than the side curve edge C portion, and the front portion is large and the rear portion is slightly warped. As described above, the corner portion of the edge L is rounded, and the back surface J of the warp is finished to a flat surface, and a snowboard-like sliding body 8 is provided. Small As a two-wheeled vehicle, the effect of the vertical groove B is added to enable stable straight traveling, and the curved edge portions of the semicircular portions G and H are rounded. Because it is finished and there are no edges, the G and H parts bite into the snow surface when turning left and right due to the inclination of the electric motorcycle, and the snow surface before the left and right side curve edges C interferes with the turn. The basis of the present invention is that the effect of only the left and right side curve edges C is exhibited by preventing this and a sharp turn is possible.

一般にはスキー、スノーボードは、其れが単体である場合においては、左右に傾けることで、サイドカーブの働きでターン操作は出来るが、後部に移動出来ない物体、今回の場合は後部にフレームと車輪が取り付くと、舵取り操作が容易に出来なくなり、前輪の舵取りが出来ない2輪車はすぐに転到する、と同様、容易に舵取り操作が出来ず直ぐにも転倒するが、今回の前方に装備された、スノーボード形状の滑降する板の側面形状は、前後が反り上がった、球形を呈しており、又横断面形状も中央部が若干凸面球状に盛り上がっており、更に平面形状は前部が広い半円状後部が狭い半円状であり其の裏部の下角を丸くしてエッジが無く其の後部の絞り込まれた部分は鋭いサイドカーブエッジが絞り込まれる様に設けられており、更に圧縮スプリングをスノーボード状滑降体の中心より、後部に設けて常に前側が持ち上がる様に工夫されている為、深雪等においてのハンドルの揺動操作が容易に出来ることに特長がある。   In general, when skiing and snowboarding is a single body, it can be turned by tilting to the left and right to operate the side curve, but cannot move to the rear, in this case the frame and wheels at the rear If it is installed, the steering operation can not be easily performed, and the two-wheeled vehicle that cannot steer the front wheels will be transferred immediately. In addition, the side shape of the snowboard-shaped sliding board has a spherical shape with the front and back warped, and the cross-sectional shape has a slightly convex spherical shape at the center, and the planar shape has a wide front part. The circular rear part is narrow semicircular, the lower corner of the back part is rounded, there is no edge, the narrowed part of the rear part is provided so that the sharp side curve edge is narrowed, From the center of the snowboard-shaped gliding member ring, since it is devised always as front side lifts provided at the rear, there is a feature that the swing operation of the steering wheel of the Miyuki etc. easily.

平坦な地面を2輪車が倒れずに走行出来る理屈は、自然の原理と人間が持っている反射神経との組み合わせにより、該2輪車を倒れる方向にハンドルを切って前進することにより解決できる、そこで今回の発明も操舵装置のスノーボード状滑降体裏面は縦長で緩やかな楕円面形状を呈しており、其の前後は反りかえり、左右は絞り込まれたサイドカーブエッジを設けた部分より下側に位置する為直進時はハンドル操作が容易であり左右のターン時には本体を傾けてハンドルを切ると直ちに前記サイドカーブエッジが雪面に食い込んで、2輪車がターンをするかの如く傾き具合に合った回転半径のターンを可能としている。   The reason why a two-wheeled vehicle can run on a flat ground without falling down can be solved by turning the steering wheel in a direction to tilt the two-wheeled vehicle and moving forward by combining natural principles and reflexes possessed by humans. Therefore, in this invention as well, the back of the snowboard-like sliding body of the steering device has a vertically long and gentle ellipsoidal shape, its front and back are warped, and the left and right are below the part where the narrowed side curve edge is provided. Because it is located, it is easy to operate the handle when going straight, and when turning left and right, the side curve edge immediately cuts into the snow surface when the handle is turned and the two-wheeled vehicle is tilted as if turning. The turn of the turning radius is possible.

図1、図3において、本発明のバイク用操舵装置10の舵取り機構の形態と機能について詳細に記すと、スノーボード状滑降体8の荷重中心点Dの前方に傾斜して、ハンドル回転中心軸の延長線Eの先端部が前記スノーボード状滑降体8の左右が固定された軸受ブラケット7にフロントサスペンションフオーク6先端部を左右に跨り軸支している軸の中心に位置して、キャスター車輪の働きと同様に直進復元性を発揮することを可能としている。   1 and 3, the configuration and function of the steering mechanism of the motorcycle steering apparatus 10 according to the present invention will be described in detail. Inclined forward of the load center point D of the snowboard-like downhill body 8, The tip of the extension line E is positioned at the center of the shaft that pivotally supports the tip of the front suspension fork 6 across the left and right sides of the bearing bracket 7 to which the left and right sides of the snowboard-like sliding body 8 are fixed. It is possible to demonstrate straight-line restoration as well as

図1、図3、図5において本発明の根幹である、スノーボード状滑降体8を設けた操舵機構について記すと、フロントサスペンションフオーク6の下部先端は、該スノーボード状滑降体8の中央下部荷重中心点よりも前方に軸支されており、前記スノーボード状滑降体8は前記フロントサスペンションフオーク6の先端軸支部Kを中心に上下にシーソー状に揺動する仕掛けになっており、更に、フロントサスペンションフオーク6パイプ上部に跨る板とスノーボード状滑降体8の中間後方上面部とが圧縮スプリング前9にて接続されており、其の作用でスノーボード状滑降体8は常に前側が前記シーソー状に揺動する仕掛けと相まって、上部方向に持ち上がる力が働いており、其の結果スノーボード状滑降体8前方の反り上がった広い半円状でエッジがない底面が雪を押しのけ易くして、その結果ハンドル操作もより軽くなり従ってより効果的な舵取り操作を可能としている。     1, 3, and 5, the steering mechanism provided with the snowboard-like downhill body 8, which is the basis of the present invention, describes the lower end of the front suspension fork 6 at the center lower load center of the snowboard-like downhill body 8. The snowboard-like downhill body 8 swings up and down like a seesaw around the tip shaft support portion K of the front suspension fork 6, and the front suspension fork is further supported. A plate straddling the upper part of the 6 pipe and the intermediate rear upper surface portion of the snowboard-like downhill body 8 are connected by the front 9 of the compression spring, and the snowboard-like downhill body 8 always swings in the seesaw shape by the action. Combined with the mechanism, the upward lifting force is working, and as a result, the snowboard-like downhill body 8 has a wide semicircular shape that warps forward. Edge there is no bottom to easily pushed snow, thereby enabling the result handle operation becomes lighter therefore more effective steering operation.

スノーボード状滑降体の全体の形状と構造においては、物が物だけに、多くの試作、試運転は言うまでも無く、縦横の比率、前後の反り上がり具合と、其の部分のエッジと左右の鋭いエッジとの境目の徐徐に変化する形状と其の位置は特に多くの試作、試運転が要求され、この部分が本発明の明暗の別れ目である事は言うまでもない、又、深雪においては多少この部分は抵抗になるが、緩やかな楕円面形状を呈した裏面滑降面の縦溝部分の左右の小さく細長いエッジIの形状は平面の雪上を直線状に走行するには2輪車に概ね近い状態でなけれ
ばならないことが望まれる。
In the overall shape and structure of a snowboard-like downhill body, not only things but also many prototypes and trial runs, not to mention the aspect ratio, the degree of warping up and down, the edge of that part and the sharpness of the left and right The gradually changing shape and the position of the boundary with the edge require a lot of trial manufacture and trial operation, and it goes without saying that this part is a part of light and dark of the present invention. However, the shape of the small and narrow edges I on the left and right of the vertical groove part of the back-sliding surface, which has a gentle elliptical shape, is generally close to that of a two-wheeled vehicle in order to run straight on snow on a flat surface. It is desirable to have to.

本発明は操縦に関しては、例えば斜面の雪面を横断走行する場合は2輪車と同様谷側に倒れ易く、其の状況の防止方法として、よくスキーの斜滑降で行うギルランデ滑降をする様にスキーの谷側のテールを滑らして蛇行滑降を行えば良いのだが、後部車輪が付いている為に横滑りを出来ないので、谷側には少し下り、山側には傾きを強くして半円を描く様に走行して、其の状況を繰り返して走行して、谷側への転倒するのを乗り切って走行するのもウィンタースポーツとしての醍醐味でもある、但し前記の状況は硬い急斜面の場合であり、其れ以外の深雪の緩斜面においてはこの限りではない。   In the present invention, for example, when driving across the snow surface of a slope, it is easy to fall to the valley side like a two-wheeled vehicle, and as a method for preventing such a situation, the Gillande downhill is often performed by ski downhill. You can slide down the tail on the ski valley and meander down, but you can't skid because of the rear wheels. It is also a real pleasure as a winter sport to run as depicted, run repeatedly, ride over the fall to the valley side, but the situation above is a case of a hard steep slope However, this does not apply to other gentle snowy slopes.

本発明は雪上走行専用タイヤ車輪を後方緩衝装置に設け、前方操舵装置にはスノーボード状特殊滑降体を設けて成る、電動駆動雪上走行用バイクであり、駆動及び充電機能を有した、モータージェネレーターとマニュアルトランスミッションとの兼ね合いを持ち、小回りが効き、軽量で、且つ低速での駆動力は抜群であり走行音も静かで、雪上においてのバイク並みの運転操作が可能であり、更に技術面での目覚ましいものがある、電動バイクとスノーボードとの効率の良い組み合わせにより、ウィンタースポーツはもとより、雪の山野でのハンテイング、更には、陸上自衛隊雪中訓練用にも適用出来て利点が多い。   The present invention is an electrically driven snow travel motorcycle, in which a tire wheel dedicated to snow travel is provided in a rear shock absorber, and a snowboard-like special downhill body is provided in a front steering device, and a motor generator having a drive and charging function, It has a balance with a manual transmission, has a small turn, is lightweight, has excellent driving power at low speed, has a quiet running sound, and can be operated like a motorcycle on snow, and it is also remarkable in terms of technology Due to the efficient combination of electric bikes and snowboards, there are many advantages that can be applied not only to winter sports, but also to hunting in the snowy mountains, and also to training for the Ground Self-Defense Force in the snow.
