【発明の詳細な説明】
この発明は、普通の自動車やオートバイに簡単に取り付
けることのできるキャタピラ装置に間する。DETAILED DESCRIPTION OF THE INVENTION The present invention is directed to a caterpillar device that can be easily installed on common automobiles and motorcycles.
車輌が雪道を走行する場合、従来はトレッドを深くした

ェーンを巻いたりしている。しかし、これらのものを用
いても、特にアイスバーンでは必ずしも満足のいく防滑
効果が得られない。Traditionally, when vehicles drive on snowy roads, they use deep treads, special tires with bins, or chains wrapped around the tires. However, even if these materials are used, a satisfactory anti-slip effect cannot always be obtained, especially in ice burns.
また、スパイクタイヤを用いた場合、路面が削られてし
まう等の問題がある。Furthermore, when spiked tires are used, there are problems such as the road surface being scraped.
この発明は、このような問題を解決するため、普通の自
動車にも簡単に取り付けられるキャタピラ装置を得るこ
とを目的とする。In order to solve these problems, the present invention aims to provide a caterpillar device that can be easily attached to ordinary automobiles.
この発明のキャタピラ装置は、主輪、フレーム、２つの
補助輪および無端ベルトからなっている。The caterpillar device of this invention consists of a main wheel, a frame, two auxiliary wheels, and an endless belt.
主輪は、タイヤ付きの車輪をそのまま流用することもて
きる。フレームは、主輪の車軸に回転自在に取り付けら
れる。２つの補助輪は、主輪とほぼ共通した接線を有す
るよう、主輪の前後において、フレームに回転自在に支
持されている。蝿端ヘルドは、主輪と補助輪を包むよう
に、これら３つの輪にかけられている。For the main wheels, wheels with tires can be used as they are. The frame is rotatably attached to the axle of the main wheels. The two auxiliary wheels are rotatably supported by the frame at the front and rear of the main wheel so as to have substantially the same tangent line as the main wheel. The fly-end heald is placed around the main and auxiliary wheels, wrapping them around the three wheels.
このキャタピラ装置では、主輪が駆動されると、無端ベ
ルト−４１−環し、これが路面をけって車輛を進める。In this caterpillar device, when the main wheels are driven, the endless belt 41 loops around and kicks off the road surface to propel the vehicle.
２つの補助輪は主輪とほぼ共通の接線を有するようフレ
ームに取り付けられており、しかも、フレームが車輌の
まわりに自由に回転できるので、主輪と２つの補助輪は
ベルトを介して常に接地する。換言すれば、ベルトは３
つの輪によって常に地面に押し付けられる。このため、
無端ベルトは、大きな接地面積を有する事ができ、路面
をしっかりと捉え、加速時や制動時にスリップを生じに
くい。The two auxiliary wheels are attached to the frame so that they have almost the same tangent line as the main wheels, and since the frame can rotate freely around the vehicle, the main wheels and the two auxiliary wheels are always in contact with the ground via belts. do. In other words, the belt is 3
It is constantly pressed to the ground by two rings. For this reason,
Endless belts have a large ground contact area, firmly grip the road surface, and are less likely to slip during acceleration or braking.
このキャタピラ装置は、一台の自動車の全車輪に適用し
てもよいし、一部のみ、例えば後輪駆動車であれば後輪
のみ、前輪駆動車であれば前輪のみに適用することもて
きる。This caterpillar device may be applied to all wheels of a single vehicle, or it may be applied to only some, for example, only the rear wheels of a rear-wheel drive vehicle, or only the front wheels of a front-wheel drive vehicle. Ru.
この発明の実施例を図面に基づいて説明する。Embodiments of the invention will be described based on the drawings.
実施例は、この発明のキャタピラ装置を乗用車ｌの後部
車軸２に取り付けたものである。車軸２に固定されてい
る主輪３は、ホイル３ａにタイヤ３ｂを嵌めたものであ
り、従来の車輪をそのまま流用してもよい。In the embodiment, the caterpillar device of the present invention is attached to the rear axle 2 of a passenger car 1. The main wheel 3 fixed to the axle 2 is a wheel 3a fitted with a tire 3b, and a conventional wheel may be used as is.
４はフレームであり、その中央に円板４ａが回転自在に
支持されており、この円板が主輪のホイル３ａと共にナ
ツト５て車軸２に取り付けられている。Reference numeral 4 denotes a frame, and a disk 4a is rotatably supported at the center of the frame, and this disk is attached to the axle 2 with a nut 5 together with a main wheel 3a.
したがって、フレーム４は、車軸２のまわりに１山に回
転することができる。Therefore, the frame 4 can rotate around the axle 2 in a single rotation.
フレーム４の前後には、主輪３を挟むように、補助輪６
が回転自在に支持されている。補助輪は、主輪３と同様
、タイヤ付きのものである。６ａは補助輪の軸である。Auxiliary wheels 6 are provided at the front and rear of the frame 4 so as to sandwich the main wheel 3.
is rotatably supported. The auxiliary wheels, like the main wheels 3, are equipped with tires. 6a is the axis of the auxiliary wheel.
７は無端のゴムベルトてあり、主輪３と２つの補助輪６
を包むように、これらにかけられている。7 is an endless rubber belt, which has a main wheel 3 and two auxiliary wheels 6.
It is hung on these so as to enclose it.
なお、前記２つの補助輪６は主輪３と共通の接線を持つ
よう取り付けてあり、したがって、無端ベルト７は側方
から見たとき三角形になり、三角形の底辺中央に主輪３
の最下部が接するようになっている。The two auxiliary wheels 6 are attached so as to have a common tangent line with the main wheel 3. Therefore, the endless belt 7 has a triangular shape when viewed from the side, and the main wheel 3 is located at the center of the base of the triangle.
The bottoms of the two are in contact with each other.
無端ヘルド７の外周面には、滑り止めのためのトレッド
８が形成されている。ベルト７の内周面には突条９が縦
通しており、これが、主輪３と補助輪６の缶タイヤの外
周面の溝３Ｃ１６Ｃに嵌合し、ベルト７が横ぶれしたり
、タイヤから外れたりしないようになっている。A tread 8 for preventing slipping is formed on the outer peripheral surface of the endless heald 7. A protrusion 9 runs longitudinally on the inner peripheral surface of the belt 7, and this fits into the groove 3C16C on the outer peripheral surface of the can tires of the main wheel 3 and the auxiliary wheel 6, and prevents the belt 7 from wobbling sideways or from the tire. It is designed so that it will not come off.
さらに、ベルト７や主輪３が空まわりしないよう、ベル
ト７の内周面と各タイヤの外周面に互いに嵌合する凹凸
が形成されている（図示しない）。Furthermore, in order to prevent the belt 7 and the main wheels 3 from spinning idly, irregularities are formed on the inner circumferential surface of the belt 7 and the outer circumferential surface of each tire so that they fit into each other (not shown).
無端ベルト７は主輪３と補助輪６の各タイヤの空気を抜
いた状態でかけ、かけた後、空気を入れて緊張させろ。Put on the endless belt 7 with the main wheel 3 and auxiliary wheel 6 tires deflated, and then put some air in there to make them tense.
使用中にベルトがゆるんだ場合も同様である。なお、ベ
ルトのゆるみを取り除くため、２つの補助輪６の間隔を
調節できるような機構を設けてもよい。The same applies if the belt becomes loose during use. In addition, in order to remove slack in the belt, a mechanism that can adjust the interval between the two auxiliary wheels 6 may be provided.
以上説明したように、この発明によれば、無端ベルトが
大きな接地面積を有するので、路面をしっかりと捉える
ことができ、タイヤだけの場合より、加速・制動時のス
リップを小さくおさえることができる。As explained above, according to the present invention, since the endless belt has a large ground contact area, it can firmly grip the road surface, and slips during acceleration and braking can be suppressed to a smaller extent than when using only tires.
また、この発明装置は、一本の車軸に取り付ける構造な
ので、普通の自動車やオートバイにも特別の改装を加え
ないで取り１寸けられるという効果がある。Furthermore, since the device of this invention has a structure that is attached to a single axle, it has the effect of being able to be installed on ordinary cars and motorcycles without any special modification.
