【発明の詳細な説明】 ［産業上の利用分野］ 本願は、雪上バイクなどの無限軌道装置を備えた車両
に使用する操向装置に関する。The present invention relates to a steering device used for a vehicle equipped with an endless track device such as a snow bike.
［従来の技術］ 車体前部のフロントフォーク下部に操向スキーを枢着
するとともに、車体後部の無限軌道装置により駆動す

として、米国特許第4613006号がある）。このような車
両の操向スキーは金属製であることが一般的である。2. Description of the Related Art A vehicle, such as a snow bike, is known in which a steering ski is pivotally mounted on a lower portion of a front fork at a front portion of a vehicle body and is driven by an endless track device at a rear portion of the vehicle body. 4613006). The steering skis of such vehicles are generally made of metal.
［発明の解決しようとする課題］ ところで、上記の操向スキーの場合、金属の雪面に対
する静止摩擦係数が比較的大きいため、裏側の雪と接触
する面（以下、接雪面という）に着雪し、これがやがて
氷結することにより、走行抵抗を増大させることがあ
る。[Problems to be Solved by the Invention] In the case of the above-mentioned steering ski, since the coefficient of static friction of the metal against the snow surface is relatively large, the ski contacts the snow contact surface on the back side (hereinafter referred to as a snow contact surface). Snow, which eventually freezes, may increase running resistance.
また、操向スキーの横幅は比較的狭くなっていること
が普通であるが、このような場合、接雪面の面圧が高く
なるので、深雪上で沈み込みを生じ雪中へもぐってしま
う現象（スタック）を生じることがある。ゆえに、耐ス
タック性を向上させて、深雪上の走破性を向上させるこ
とも望まれている。In addition, the width of the steered ski is usually relatively narrow, but in such a case, the surface pressure on the snow contact surface becomes high, causing sinking on deep snow and passing through the snow. A phenomenon (stack) may occur. Therefore, it is also desired to improve the stacking resistance and improve the running performance on deep snow.
そこで本願は、かかる諸点を解決できる無限軌道車両
の操向装置を提供することを目的とする。Therefore, an object of the present application is to provide a steering device for a tracked vehicle that can solve such points.

着脱自在に取付けたことを特徴とする。[Means for Solving the Problems] In order to solve the above problems, the invention of claim 1 overlaps a plastic ski cover on at least the back side of the steering ski, and the ski cover is viewed in plan. The main sliding part has a main sliding part which is substantially parallel to the left and right sides and extends in the front-rear direction. The width of the main sliding part is wider than the width corresponding to the steering ski, and the steering ski protrudes upward on the left and right sides of the main sliding part. The right and left sides of the steering ski are provided with rising portions that overlap from the outside, and are detachably attached to the left and right sides of the steered ski at the rising portions.
また、請求項第２項の発明は、スキーカバーの左右両
側部に、操向スキー左右両側よりもさらに長く側方へ延
出した幅広部を設けたことを特徴とする。The invention according to claim 2 is characterized in that wide portions extending laterally longer than both left and right sides of the steered ski are provided on both left and right sides of the ski cover.
［発明の作用］ 操向スキーの接雪面に取付けたスキーカバーはプラス
チック製のため、金属に比べ雪に対する静止摩擦係数が
小さくなる。このため、スキーカバーに対して着雪しに
くくなる。その結果、雪が氷結することによる走行抵抗
の増大を防止し易くなる。[Operation of the Invention] Since the ski cover attached to the snow contact surface of the steered ski is made of plastic, the coefficient of static friction against snow is smaller than that of metal. For this reason, it is difficult to snow the ski cover. As a result, it is easy to prevent an increase in running resistance due to freezing of snow.
また、スキーーカパーの主滑走部左右両側部に上方へ
突出する立ち上がり部を設け、この立ち上がり部を操向
スキーの左右両側面へ外方から重ねて側面にて着脱自在
に取付けたので、滑走時に取付部が雪に接触しにくくな
り、走行時に雪面側から加えられる抵抗である雪面抵抗
を減少させる。In addition, there is a rising part that protrudes upward on the left and right sides of the main sliding part of the ski cover, and this rising part is attached to the left and right sides of the steering ski from outside and attached detachably on the side, so it is attached when sliding This makes it harder for the part to come into contact with snow, and reduces snow surface resistance, which is resistance applied from the snow surface side during traveling.
さらに、平面視で主滑走部の横幅を操向スキーの対応
部分横幅よりも広くしたので、旋回時にもプラスチック
部材であるスキーカバーの左右両側部が雪面へ接触し易
くなるので旋回時の雪面抵抗を減少させる。Furthermore, since the width of the main sliding portion in the plan view is wider than the corresponding portion of the steering ski, the left and right sides of the plastic ski cover, which is a plastic member, can easily come into contact with the snow surface even when turning, so that the snow when turning can be easily obtained. Reduces sheet resistance.
そのうえ、スキーカバーの左右両側部に、操向スキー

スタック性が向上する。しかも、旋回時にこの幅広部が
雪面へ接触するので、前記旋回時の雪面抵抗をさらに減
少させる。In addition, if the left and right sides of the ski cover are provided with wide portions extending laterally longer than the left and right sides of the steered ski, the width of the ski cover will be wider than that of the steered skis. Therefore, since the surface pressure on the snow contact surface is reduced, it is difficult to sink even on deep snow, and the stacking resistance is improved. In addition, since the wide portion comes into contact with the snow surface during turning, the snow surface resistance during the turning is further reduced.
