Description
本発明は車両用クローラの滑り止め構造、板状フック構造および車両用クローラの滑り止め方法に係り、特に、農林業、土木・建設業等で用いられるクローラ装備車両において、これに装着することによってクローラの滑り止め効果を得ることのできる、車両用クローラの滑り止め構造、板状フック構造および車両用クローラの滑り止め方法に関するものである。 The present invention relates to a vehicle crawler anti-slip structure, a plate-like hook structure, and a vehicle crawler anti-slip method, and in particular, in a crawler-equipped vehicle used in agriculture, forestry, civil engineering, construction, etc. The present invention relates to an anti-slip structure for a crawler for a vehicle, a plate-like hook structure, and a non-slip method for the crawler for a vehicle that can obtain an anti-slip effect of the crawler.
車両用クローラとして一般的なゴムクローラは、駆動輪に掛渡される所定の幅のループ状の帯体であり、その上に所定間隔で凸条のラグが設けられ、ラグ間には凹条部が形成されている構成である。ゴムクローラは駆動輪の回転を受けて無限軌道で周回し、これによりラグが地面に食い込むことによって、車両は走行することができる。 A rubber crawler generally used as a crawler for a vehicle is a loop-shaped belt body having a predetermined width that is stretched over a drive wheel, and convex lugs are provided on the belt at predetermined intervals. Is formed. The rubber crawler circulates in an endless track in response to the rotation of the driving wheel, and the rug bites into the ground so that the vehicle can travel.
しかしラグは突出高さが一定に形成されているため、泥濘・積雪・凍結等の悪路の場合には凹条部に土や雪が入り込み、クローラの接地面が平滑、平坦になってしまう。これにより走行面に対するラグの食い込みが不十分または不可能となって滑りが発生し、車両走行に支障を来すことがあった。かかる問題に対処する技術的提案が、従来なされている。 However, since the lugs are formed with a constant protrusion height, dirt and snow enter the concave streak in the case of rough roads such as mud, snow, and freezing, and the ground contact surface of the crawler becomes smooth and flat. As a result, the lag biting into the running surface is insufficient or impossible and slipping occurs, which may impede vehicle running. Technical proposals for dealing with such problems have been made.
たとえば後掲特許文献1には、車両用クローラに装着される滑り止め具として、クローラの帯体の各側端部に係合するそれぞれ一対のフック部材と、フック部材同士を連結するチェーンと、フック部材に連係しラグの上面よりも突出するように形成された突起部材とを備え、かつ、チェーンを左右に分断可能に連結する連結リンクをチェーンの途中に設けた構成が、開示されている。 For example, Patent Document 1 listed below includes a pair of hook members that engage with each side end portion of a crawler belt as a slip prevention device attached to a crawler for a vehicle, a chain that connects the hook members to each other, And a protrusion member formed so as to project from the upper surface of the lug and linked to the hook member, and a connection link for connecting the chain in a severable manner is provided in the middle of the chain. .
しかし当該文献開示の滑り止め具には、下記の問題点がある。
ア) 両側端部に係止しラグや凹状部と平行に装着される当該滑り止め具は、その直交方向である車両走行方向に対しては一定の滑り止め効果を期待できるものの、平行方向に対しては滑り止め効果が弱い。つまり、横滑りに対して弱い。
イ) したがって、平行方向の成分を有する斜め方向に対しても、滑り止め効果が弱い。
ウ) したがって、水平な悪路であれば一定の滑り止め効果を得られるものの、山間地など、一箇所において、または走行方向上において、多様に傾斜成分を含むような場合には、安定的な滑り止め効果が得られない。
However, the anti-skid tool disclosed in the document has the following problems.
A) The anti-skid device that is locked to both ends and mounted in parallel with the lug or concave part can be expected to have a certain anti-slip effect in the vehicle running direction, which is the orthogonal direction, but in the parallel direction. On the other hand, the anti-slip effect is weak. That is, it is weak against skidding.
B) Therefore, the anti-slip effect is weak even in an oblique direction having a parallel component.
C) Therefore, it is possible to obtain a certain anti-skid effect on a horizontal rough road, but it is stable in the case where various slope components are included in one place such as a mountainous area or in the traveling direction. The anti-slip effect cannot be obtained.
エ) クローラ帯体への係止が、一方側端部あたり二のフック部材によってなされるため、チェーン間に泥濘や雪が絡まり、詰まり易く、塊ができ、結局、クローラの接地面が平坦になり易く、十分な滑り止め効果が得られない。
オ) 滑り止め効果は二箇所の突起部材のみによるものであるため、不十分であり、より十全な効果が望まれる。
カ) 全体構造が複雑であり、その分、取り扱い方法にも煩雑な点がある。
D) Since the crawler belt is locked by two hook members per one end, mud and snow are entangled between the chains, easily clogging, forming a lump, and eventually the crawler grounding surface becomes flat. It is easy and a sufficient anti-slip effect cannot be obtained.
E) Since the anti-slip effect is due to only two protruding members, it is insufficient and a more complete effect is desired.
F) The overall structure is complicated and the handling method is complicated accordingly.
そこで本発明が解決しようとする課題は、かかる従来技術の問題点をなくし、水平な悪路のみならずあらゆる悪路に対応可能であり、滑り止め効果も安定的かつ十分に得られ、取り扱いもより簡単な、実用性の高い車両用クローラの滑り止め構造を提供することである。 Therefore, the problem to be solved by the present invention is to eliminate such problems of the prior art, and can deal with not only horizontal rough roads but also any bad roads, and the anti-slip effect can be obtained stably and sufficiently, and handling is also possible. It is an object of the present invention to provide a simpler and more practical non-slip structure of a vehicle crawler.
本願発明者は上記課題について検討した結果、クローラの帯体に係止する部材を各側端部あたり板状に形成した単一部材とし、滑り止め機能を発揮する部位をより多く設けること等によって解決できることを見出し、これに基づいて本発明を完成するに至った。すなわち、上記課題を解決するための手段として本願で特許請求される発明、もしくは少なくとも開示される発明は、以下の通りである。 As a result of studying the above problems, the inventor of the present application has formed a single member that is formed in a plate shape around each side end portion of the member that is locked to the crawler belt body, and by providing more parts that exhibit an anti-slip function, etc. Based on this finding, the present inventors have completed the present invention.

本発明の車両用クローラの滑り止め構造、板状フック構造および車両用クローラの滑り止め方法は上述のように構成されるため、これによれば農林業・土木・建設業等で用いられるクローラ装備車両において、水平な悪路のみならず泥濘・積雪・凍結等のあらゆる悪路で、安定的かつ十分なクローラの滑り止め効果を得ることができる。しかも従来技術と比較して取り扱いも簡単であり、実用的である。 The vehicle crawler anti-slip structure, the plate-like hook structure and the vehicle crawler anti-slip method of the present invention are configured as described above, and according to this, the crawler equipment used in agriculture, forestry, civil engineering, construction, etc. In a vehicle, a stable and sufficient crawler anti-slip effect can be obtained not only on a horizontal rough road but also on every bad road such as mud, snow and freezing. In addition, it is easier to handle and practical than the prior art.
また、本発明の車両用クローラの滑り止め構造等によれば、車両走行方向のみならず他の方向に対しても十分な滑り止め効果が得られる。つまり、横滑りにも、斜め方向への滑りに対しても強い。したがって、たとえば山間地など、一箇所において、または走行方向上において多様に傾斜成分を含むような場合であっても、安定的かつ十分な滑り止め効果を得ることができる。 In addition, according to the anti-slip structure of the vehicle crawler of the present invention, a sufficient anti-slip effect can be obtained not only in the vehicle traveling direction but also in other directions.

Therefore, a stable and sufficient anti-slip effect can be obtained even in a case where various slope components are included in one place such as a mountainous area or in the traveling direction.
また、本発明の車両用クローラの滑り止め構造等によれば、クローラ帯体への係止が一方側端部あたり一のみの板状フック構造によってなされるため、従来技術のような泥濘や雪が絡まり、詰まり、クローラの接地面が平坦になり易くなる、という問題が全く発生せず、十分な滑り止め効果が持続的に得られる。 Further, according to the anti-slip structure of the crawler for a vehicle of the present invention, since the locking to the crawler belt body is made by only one plate-like hook structure per one side end, mud and snow as in the prior art are prevented. There is no problem of entanglement, clogging, and the contact surface of the crawler tends to be flat, and a sufficient anti-slip effect can be obtained continuously.
さらに、本発明の車両用クローラの滑り止め構造等によれば、各板状フック構造上に設けられる一または複数の制動手段とともに、連結構造自体も制動手段として機能するため、一層確実、強力な滑り止め効果が得られる。加えて本発明の滑り止め構造は、基本的に二の板状フック構造と連結構造からなる簡素な構成のため、製造上、取り扱い上も有利であり、実用性が高い。 Furthermore, according to the anti-slip structure of the vehicle crawler of the present invention, the coupling structure itself functions as a braking means together with one or a plurality of braking means provided on each plate-like hook structure. Anti-slip effect is obtained. In addition, the anti-slip structure of the present invention has a simple configuration basically consisting of two plate-like hook structures and a connecting structure, and is advantageous in terms of manufacturing and handling, and is highly practical.
以下、図面により本発明を詳細に説明する。
図1A、1Bは、車両用クローラの滑り止め構造の構成例を示す説明図であり、図1Aは連結前、図1Bは連結後の状態を示す。これらに示すように本発明の車両用クローラの滑り止め構造50は、ループ状の帯体と、帯体に複数設けられた凸状のラグと、ラグ間に形成された凹条部とを備えた車両用クローラにおける滑り止め構造であって、帯体の各側端部に係止する二の板状フック構造10、20と、各板状フック構造10、20の間を連結する連結構造30と、クローラの滑り止めをするための制動手段とを備えてなり、制動手段は、板状フック構造上に設けられる制動手段14、24の他、連結構造30自体もまた制動手段として機能するようになされていることを、主たる構成とする。
Hereinafter, the present invention will be described in detail with reference to the drawings.
1A and 1B are explanatory views showing a configuration example of the anti-slip structure of a crawler for a vehicle. FIG. 1A shows a state before connection, and FIG. 1B shows a state after connection. As shown in these figures, the anti-slip structure 50 for a vehicle crawler according to the present invention includes a loop-shaped belt body, a plurality of convex lugs provided on the belt body, and a concave strip formed between the lugs. The anti-slip structure for the vehicle crawler includes two plate-like hook structures 10 and 20 that are engaged with the respective side end portions of the belt, and a connection structure 30 that connects the plate-like hook structures 10 and 20. And a brake means for preventing the crawler from slipping. The brake means is configured such that the connecting structure 30 itself functions as the brake means in addition to the brake means 14 and 24 provided on the plate-like hook structure. It is assumed that the main structure is that
なお図では、各板状フック構造10、20上にはそれぞれ一個ずつの制動手段14、24が設けられた構成であるが、設ける制動手段の数はこれに限定されず、複数個であってもよい。また、板状フック構造10、20上の制動手段14等は、図示するように単純に突起部として形成することで、十分に機能を果たす。なお、突起部の具体的形状は限定されない。つまり、図示する単純な凸状形状のみならず、別の形状であってもよい。 In the figure, the plate-like hook structures 10 and 20 are provided with one braking means 14 and 24, respectively. However, the number of braking means provided is not limited to this, and a plurality of braking means are provided. Also good. Further, the braking means 14 and the like on the plate-like hook structures 10 and 20 sufficiently function by being simply formed as protrusions as shown. In addition, the specific shape of a projection part is not limited. That is, not only the simple convex shape shown in the figure but also another shape may be used.
かかる構成により本滑り止め構造50は、車両用クローラのループ状の帯体の各側端部にそれぞれ板状フック構造10、20が係止部位17、27によって係止され、かつ各板状フック構造10、20の間は連結構造30により連結された状態で、帯体上に装着される。装着状態で車両を走行させると、板状フック構造上の制動手段14、24、および同様に制動手段として機能する連結構造30が走行面(地面)に確実かつ強力に食い込み、たとえ泥濘・種々の状態の積雪・凍結による悪路であっても、またたとえば山間地など一箇所において、または走行方向上において多様に傾斜成分を含むような場合であっても、横滑りもせず、安定的、持続的かつ十分な滑り止め効果を得ることができる。 With this configuration, the anti-slip structure 50 is configured such that the plate-like hook structures 10 and 20 are locked by the locking portions 17 and 27 at the respective side end portions of the loop-shaped belt body of the vehicle crawler. The structures 10 and 20 are mounted on the band while being connected by the connecting structure 30. When the vehicle is run in the mounted state, the braking means 14 and 24 on the plate-like hook structure and the connecting structure 30 that similarly functions as the braking means bite into the running surface (ground) reliably and strongly, Even if it is a rough road due to snow and freezing in the state, or in a case where various slope components are included in one place such as a mountainous area or in the running direction, it does not skid and is stable and sustainable In addition, a sufficient anti-slip effect can be obtained.
図2は、本発明の滑り止め構造の別の構成例を示す説明図である。
本滑り止め構造における連結構造は、図1A等の構成例の連結構造30のように、各板状フック構造10、20とは独立したものとして、使用時にこれらを連結する構成としてもよいし、図2の例に示す連結構造230のように一方の板状フック構造210に予め固定済みの構成としてもよい。また、連結構造30等と板状フック構造10等との間の連結方式は、各図に示すように、連結構造30等の連結用部位31等と、板状フック構造10等側の連結用部位13等とを、適宜の方法にて連結する方式とすることができる。たとえば環状のフック等である。なお、これに関わらず、二の板状フック構造10、20間を確実、安定的に連結できる手段であれば、後述する実施例のような方式も含め、いかなる方法であってもよい。
FIG. 2 is an explanatory view showing another configuration example of the anti-slip structure of the present invention.
The connection structure in the anti-slip structure may be configured so as to be independent from the respective plate-like hook structures 10 and 20 as in the connection structure 30 in the configuration example of FIG. A configuration in which the plate-like hook structure 210 is fixed in advance as in the connection structure 230 shown in the example of FIG. In addition, as shown in each drawing, the connection method between the connection structure 30 and the like and the plate-like hook structure 10 and the like is as follows. It can be set as the system which connects the site | part 13 grade | etc., With an appropriate method. For example, an annular hook or the like. Regardless of this, as long as it is a means that can reliably and stably connect the two plate-like hook structures 10 and 20, any method including a system as in an embodiment described later may be used.
図3は、本発明の滑り止め構造のまた別の構成例を示す要部説明図である。図示するように本滑り止め構造の板状フック構造310上の制動手段は、上述したように二以上設けるものとすることができる。図の例では、制動手段314、315の二個が設けられているが、もちろん三個以上であってもよい。また形状に限定されないことも、上述のとおりである。 FIG. 3 is a main part explanatory view showing still another configuration example of the anti-slip structure of the present invention. As shown in the figure, two or more braking means on the plate-like hook structure 310 of the present non-slip structure can be provided as described above. In the example shown in the figure, two braking means 314 and 315 are provided. Of course, three or more braking means may be provided. Moreover, it is as above-mentioned that it is not limited to a shape.
板状フック構造ごとに制動手段を複数設ける場合は、図示するように、一つは板状フック構造310の使用時における外側端部に制動手段314のように設け、一つは内側端部側に制動手段315のように設けることが推奨される。本滑り止め構造がクローラに装着された状態において、全体の中央部には制動手段として機能する連結構造が位置しているが、全方向に対する制動効果(走行面に対する食い込み効果)をより良好に得るために、各制動手段相互を適度に離間させることが有効だからである。 When a plurality of braking means are provided for each plate-like hook structure, as shown in the figure, one is provided like a braking means 314 at the outer end when the plate-like hook structure 310 is used, and one is on the inner end side. It is recommended to provide the same as the braking means 315. In the state where the anti-slip structure is mounted on the crawler, a connecting structure that functions as a braking means is located at the center of the entire structure, but the braking effect in all directions (the effect of biting on the running surface) is obtained better. For this reason, it is effective to appropriately separate the respective braking means.

FIG. 4 is an explanatory view showing the configuration of the plate-like hook structure of still another configuration example of the anti-slip structure of the present invention. Also,
FIG. 5 is a plan view showing a state in which the anti-slip structure shown in FIG.
6 is a cross-sectional view taken along arrow VI-VI in FIG.
7 is a cross-sectional view taken along arrow VII-VII in FIG.
FIG. 8 is a side view taken along the line VIII in FIG. In addition, in each of these drawings, the connecting structure 430 and its connecting part are conceptually shown, and are not limited to the illustrated forms.
各図に示すように本滑り止め構造450の板状フック構造410等は、帯体Cにおける一または複数の凸状部(凸状のラグ)C8を覆うよう、被覆部位418等を備えた形状に形成されている。これにより、被覆部位418等が帯体Cの凸状部C8を被覆した状態で板状フック構造410等が帯体Cに装着されるため、確実かつ安定した装着状態が維持される。 As shown in each figure, the plate-like hook structure 410 etc. of the anti-slip structure 450 has a shape provided with a covering portion 418 etc. so as to cover one or more convex portions (convex lugs) C8 in the band C. Is formed. Thus, since the plate-like hook structure 410 and the like are attached to the band C in a state where the covering portion 418 and the like cover the convex portion C8 of the band C, a reliable and stable mounting state is maintained.
なお、連結構造430等としてはチェーンを好適に用いることができる。もちろん、二の板状フック構造410、420等を確実、安定的かつ強固に連結でき、しかもそれ自体制動手段として機能し得るものである限り、如何なるものであってもよいが、チェーンは本発明に係る連結構造として、作用効果およびコスト面から最適な一つといえる。 A chain can be suitably used as the connection structure 430 and the like. Of course, as long as the two plate-like hook structures 410, 420, etc. can be reliably, stably and firmly connected, and can function as braking means, the chain is not limited. It can be said that the connection structure according to the above is one of the most suitable from the viewpoints of operational effects and cost.
なおまた、上述文献開示技術の滑り止め用具のように、各フック部材にチェーンを設けてそれらを連結リンクでつなぐ、という複雑な構成は、本発明では不要である。本発明の滑り止め構造450においては、一本のみのチェーンによって連結構造430等として機能できる。しかも、一本のチェーンによって連結することにより、雪・氷等が絡まることがなく、したがって塊が発生するということもなく、これらを除去するために作業中断したり、効率が低下する事態を防止することができ、継続的に円滑な作業を実施することができる。 Further, as in the anti-skid tool of the above-mentioned document disclosure technique, a complicated configuration in which a chain is provided on each hook member and they are connected by a connecting link is not necessary in the present invention. The anti-slip structure 450 of the present invention can function as the connection structure 430 or the like with only one chain. Moreover, by connecting with a single chain, there is no entanglement of snow, ice, etc., and therefore no clumps are generated, preventing work interruptions or removal of efficiency to remove them. Can be performed continuously and smoothly.
本発明滑り止め構造に係る連結構造の態様は、板状フック構造とは独立した態様(図1A、1B)、一方の板状フック構造に付設された態様(図2)に限定されない。すなわち、図示しないが、各板状フック構造にそれぞれ連結構造が設けられていて、これらが相互に係合するよう形成されている構成であってもよい。この場合、各連結構造同士の連結は直接なされる方式でもよいし、別の連結用部材により連結される方式でもよい。 The aspect of the connection structure according to the anti-slip structure of the present invention is not limited to the aspect independent of the plate-like hook structure (FIGS. 1A and 1B) and the aspect attached to one of the plate-like hook structures (FIG. 2). That is, although not shown in the drawings, a connection structure may be provided for each plate-like hook structure, and these may be configured to engage with each other. In this case, the connection structures may be connected directly or may be connected by another connecting member.
以上説明した本発明滑り止め構造を構成可能な、あるいは構成するための板状フック構造自体もまた、本発明の範囲内である。また、本発明に係る車両用クローラの滑り止め構造、および板状フック構造の材料や仕様は特に限定されない。要するに車両用クローラに装着して十分な滑り止め機能を維持できる物性を備えた材料であれば、金属その他適宜公知の材料を用いることができる。また、サイズその他の仕様も、クローラの仕様に合わせる等して適宜に設計可能である。 The plate-like hook structure itself that can or can constitute the anti-slip structure of the present invention described above is also within the scope of the present invention. Moreover, the materials and specifications of the anti-slip structure of the vehicle crawler and the plate-like hook structure according to the present invention are not particularly limited. In short, any other known material can be used as long as it is a material having physical properties that can be mounted on a crawler for a vehicle and maintain a sufficient anti-slip function. Also, the size and other specifications can be appropriately designed according to the crawler specifications.
以上説明した車両用クローラの滑り止め構造を、対象の車両用クローラに装着して行う滑り止め方法もまた、本発明の範囲内である。滑り止め構造は、一方のクローラあたり複数個を装着して用いることにより、本発明の所期の目的を十分に果たすことができる。なおクローラあたりの装着個数は、後述するように6個以上とすることが望ましい。また、各滑り止め構造間は等間隔または略等間隔(均等または略均等)とすることが望ましい。効果がより安定、確実となるからである。 An anti-slip method in which the anti-slip structure for a vehicle crawler described above is mounted on a target vehicle crawler is also within the scope of the present invention. By using a plurality of anti-slip structures mounted on one crawler, the intended purpose of the present invention can be sufficiently achieved. The number of mounted units per crawler is preferably 6 or more as will be described later. In addition, it is desirable that the anti-slip structures are equidistant or substantially equidistant (equal or substantially equal). This is because the effect is more stable and reliable.
以下、本発明の実施例を簡単に説明するが、本発明がこれに限定されるものではない。
<車両用クローラの滑り止め構造、およびそれを用いた滑り止め方法>
図9、10は、本発明実施例をクローラに装着した状態の写真図であり、それぞれ前方からと、側方からの写真図である。なお、装着対象は林業用車両であり、かかる状態で木材を積載して山間地における泥道や積雪の道を走行したところ、横滑りの防止も含め、十分な滑り止め効果を得ることができた。しかも走行中、泥濘や雪が滑り止め構造(用具)に絡まったり詰まったりすることもなく、極めて安定した滑り止め効果を得ることができた。なお、図9、10に示す例では左右各クローラに8個ずつ滑り止め構造を装着する例を示している。8個の滑り止め構造はクローラ全長に対し均等または略均等に装着されており、かかる構成により本実施例では、走行路面に対して常に4箇所で滑り止め構造が機能し、その結果、良好な滑り止め効果を得ることができた。
Examples of the present invention will be briefly described below, but the present invention is not limited thereto.
<Anti-slip structure of vehicle crawler and anti-slip method using the same>
9 and 10 are photographic views of the present embodiment mounted on a crawler, respectively, from the front and from the side. The target for installation was a forestry vehicle. When wood was loaded in such a state and traveled on muddy roads and snowy roads in mountainous areas, a sufficient anti-slip effect including prevention of skidding was obtained. Moreover, during running, mud and snow were not entangled or clogged with the anti-slip structure (tool), and an extremely stable anti-slip effect could be obtained. In the example shown in FIGS. 9 and 10, an example in which eight anti-slip structures are attached to each of the left and right crawlers is shown. The eight anti-skid structures are mounted equally or substantially uniformly with respect to the entire length of the crawler, and in this embodiment, the anti-slip structure always functions at four locations on the traveling road surface. An anti-slip effect was obtained.
図11〜17は本発明実施例の外観形態を示す図であり、順に、連結状態の実施例の正面図、背面図、側面図(左右共通)、平面図、底面図、左上前方からの斜視図、右下後方からの斜視図である。また、図18は右方側の板状フック構造の左上前方からの斜視図、図19は左方側の板状フック構造の右上前方からの斜視図である。これら各図に示すように本実施例の車両用クローラの滑り止め構造550は、クローラ帯体(図示せず)の各側端部に係止する二の板状フック構造510、520と、各板状フック構造510、520の間を連結する連結構造530と、クローラの滑り止めをするための制動手段とを備えてなり、制動手段は、板状フック構造510、520上に設けられる制動手段514、524の他、連結構造530自体もまた制動手段として機能するように構成されている。なお、制動手段514、524は、本実施例のように単純に突起部として形成することで十分に機能を果たすことを確認済みだが、上述したように突起部の具体的形状は限定されない。つまり、図示する単純な凸状形状のみならず、別の形状であってもよい。 11-17 is a figure which shows the external appearance form of an Example of this invention, and is the front view of a connection state of an Example, a rear view, a side view (right and left common), a top view, a bottom view, and a perspective from the upper left front. It is a perspective view from the lower right rear figure. FIG. 18 is a perspective view from the upper left front of the plate hook structure on the right side, and FIG. 19 is a perspective view from the upper right front of the plate hook structure on the left side. As shown in these drawings, the vehicle crawler anti-slip structure 550 of this embodiment includes two plate-like hook structures 510 and 520 that are engaged with each side end of a crawler belt (not shown), A connecting structure 530 for connecting the plate-like hook structures 510 and 520 and a braking means for preventing the crawler from slipping are provided. The braking means is provided on the plate-like hook structures 510 and 520. In addition to 514 and 524, the connecting structure 530 itself is also configured to function as braking means. The braking means 514 and 524 have been confirmed to function sufficiently by being simply formed as protrusions as in this embodiment, but the specific shape of the protrusions is not limited as described above. That is, not only the simple convex shape shown in the figure but also another shape may be used.
かかる構成により本滑り止め構造550は、車両用クローラのループ状の帯体の各側端部にそれぞれ板状フック構造510、520が係止部位517、527によって係止され、かつ各板状フック構造510、520の間は連結構造530により連結された状態で、帯体上に装着されて用いられる。実際に、非公開状態にて装着状態で車両を走行させたところ、板状フック構造上の制動手段514、524、および同様に制動手段として機能する連結構造530が走行面(地面)に確実かつ強力に食い込み、たとえ泥濘・種々の状態の積雪・凍結による悪路であっても、またたとえば山間地など一箇所において、または走行方向上において多様に傾斜成分を含むような場合であっても、横滑りもせず、安定的、持続的かつ十分な滑り止め効果を得ることができた。 With this configuration, the anti-slip structure 550 includes the plate-like hook structures 510 and 520 that are locked to the respective side end portions of the loop-shaped belt body of the vehicle crawler by the locking portions 517 and 527, and the plate-like hooks. The structures 510 and 520 are connected to each other by a connecting structure 530 and mounted on a band body. Actually, when the vehicle is run in a state of being mounted in a non-disclosure state, the braking means 514 and 524 on the plate-like hook structure and the connecting structure 530 that similarly functions as the braking means are securely and securely on the running surface (ground). Even if it is a bad road due to strong bite, mud, snow in various states, freezing, etc., even if it includes various slope components in one place such as a mountainous area or in the running direction, Stable, persistent and sufficient anti-slip effect could be obtained without skidding.
各図に示すように、本実施例滑り止め構造550の板状フック構造510、520上の制動手段としては、内側端部側の制動手段514、524のみならず、外側端部の制動手段515、525も設けられている。このように、各制動手段相互が適度に離間した構成により、本滑り止め構造がクローラに装着された場合において、全体の中央部には制動手段として機能する連結構造530が位置し、かつ、全方向に対する制動効果すなわち走行面に対する食い込み効果がより良好に得られる。 As shown in the drawings, the braking means on the plate-like hook structures 510 and 520 of the anti-slip structure 550 of this embodiment are not only the braking means 514 and 524 on the inner end side but also the braking means 515 on the outer end part. 525 are also provided. As described above, when the anti-slip structure is mounted on the crawler, the connecting structure 530 functioning as the braking means is located in the central portion of the entire anti-slip structure by the configuration in which the respective braking means are appropriately separated from each other. The braking effect with respect to the direction, that is, the biting effect with respect to the running surface can be obtained better.
殊に、突起状をなす外側端部の制動手段515、525により、走行面に対する食い込み効果がより一層向上し、より一層横滑り、斜め方向への滑りに対して強いものとなっている。特に本実施例のように制動手段515、525が板状フック構造510、520の最外端に設けられた構成では、その効果が大きい。 In particular, the braking means 515 and 525 at the outer end portion having a protruding shape further improve the biting effect on the running surface, and is more resistant to side-slip and slip in an oblique direction. In particular, in the configuration in which the braking means 515 and 525 are provided at the outermost ends of the plate-like hook structures 510 and 520 as in the present embodiment, the effect is great.
また本実施例では、板状フック構造510、520の係止部位517、527を構成するところの¬状(かぎ状)部の端部がそのまま、制動手段515、525を形成している形態である。かかる構造は、形態としても簡素であって製造上有利である他、デザインとしても好ましい。高い走行面に対する食い込み効果、横滑り、斜め方向への滑りに対する高い滑り止め効果が得られることは、いうまでもない。 In the present embodiment, the end portions of the ¬-shaped (key-shaped) portions constituting the locking portions 517 and 527 of the plate-like hook structures 510 and 520 form the braking means 515 and 525 as they are. is there. Such a structure is simple in form and advantageous in manufacturing, and is also preferable in design. It goes without saying that a high biting effect on a high running surface, a side slip, and a high anti-slipping effect against slipping in an oblique direction can be obtained.
さらに本実施例では、制動手段515、525には凹部が一箇所設けられ、その端部の立体形状は平坦ではない。かかる構成は制動効果、滑り止め効果を一層高め、さらなる食い込み効果、横滑り、斜め方向への滑りに対する滑り止め効果を得ることができている。 Furthermore, in this embodiment, the braking means 515, 525 is provided with one recess, and the three-dimensional shape of the end is not flat. Such a configuration further enhances the braking effect and the anti-slip effect, and can obtain a further biting effect, a side slip, and an anti-slip effect against slipping in an oblique direction.
なお、外側端部の制動手段が本実施例の制動手段515、525のような形態に限定されないことはいうまもない。立体形状も、凹部ではなく凸部でもよいし、両方あってもよいし、さらに凹部・凸部の具体的形状も、またこれらが設けられる数も限定されない。 Needless to say, the braking means at the outer end is not limited to the form of the braking means 515, 525 of this embodiment. The three-dimensional shape may be a convex portion instead of the concave portion, or may be both, and the specific shape of the concave portion and the convex portion and the number of these provided are not limited.
くわえて、本実施例構成に関わらず、板状フック構造上のもの、連結手段併用のものに限らずに、本発明の制動手段の少なくともいずれかにおいて、凹部または凸部の少なくともいずれかが一箇所以上設けられた構成であっても、本発明の範囲内である。 In addition, regardless of the configuration of the present embodiment, not only those on the plate-like hook structure and those using the connecting means, but in at least one of the braking means of the present invention, at least one of the concave portion or the convex portion is one. Even a configuration provided at more than one place is within the scope of the present invention.
各図に示すように本実施例滑り止め構造550の板状フック構造510、520は、クローラの帯体における一または複数の凸状部(凸状のラグ 図示せず)を覆うよう、被覆部位518、528を備えた形状に形成されている。これにより、被覆部位518等が帯体Cの凸状部を被覆した状態で板状フック構造510等が帯体に装着されるため、確実かつ安定した装着状態を維持することができた。 As shown in the drawings, the plate-like hook structures 510 and 520 of the anti-slip structure 550 of this embodiment are covered with a covering portion so as to cover one or a plurality of convex portions (convex lugs not shown) in the crawler belt. 518 and 528 are formed in a shape. As a result, the plate-like hook structure 510 and the like are attached to the band while the covering portion 518 and the like cover the convex portion of the band C, and thus a reliable and stable mounting state can be maintained.
本実施例滑り止め構造550の連結構造530は、図18、19等に示すように、一方の板状フック構造520に予め固定済みのチェーンである。作用効果およびコスト面から、チェーンの使用で十分であることが確認された。そして、連結構造530と板状フック構造510との間の連結方式は、各図に示すように、連結構造530の連結用部位531と、板状フック構造510側の連結用部位513とを、連結用部材56によって連結する方式である。 The connection structure 530 of the anti-slip structure 550 of this embodiment is a chain that is fixed in advance to one plate-like hook structure 520 as shown in FIGS. It was confirmed that the use of a chain was sufficient from the viewpoint of operation and cost. And as shown in each figure, the connection method between the connection structure 530 and the plate-like hook structure 510 includes a connection part 531 of the connection structure 530 and a connection part 513 on the plate-like hook structure 510 side. This is a method of connecting by a connecting member 56.
具体的には、チェーンの末端の環である連結用部位531を、U字状をなす連結用部位513の開口端部より内側に入り込ませ、ピン形の連結用部材56を連結用部位513、連結用部位531に挿通させて固定し、連結する方式である。かかる連結方式により本実施例滑り止め構造550は、両板状フック構造510、520が確実かつ強固に連結された状態でクローラに装着され、作業上、十分な滑り止め効果を得ることができた。なお、図19に示す一方の板状フック構造510斜視図では、連結用部材56が連結用部位513に取り付けられている状態を示すものである。 Specifically, the connecting portion 531 which is the ring at the end of the chain is made to enter inside the opening end portion of the connecting portion 513 having a U-shape, and the pin-shaped connecting member 56 is connected to the connecting portion 513, In this method, the connection portion 531 is inserted and fixed to be connected. With this connection method, the anti-slip structure 550 of this embodiment is mounted on the crawler in a state where both plate-like hook structures 510 and 520 are securely and firmly connected, and a sufficient anti-slip effect can be obtained in the work. . In the perspective view of one plate-like hook structure 510 shown in FIG. 19, the connecting member 56 is attached to the connecting portion 513.
本実施例の滑り止め構造550においては、先行技術の滑り止め用具のような複雑な構成は不要であり、連結構造530であるところの一本のみのチェーンによって完全に機能できる。しかも、一本のチェーンによって連結する方式により、雪・氷等が絡まって塊ができるということも、全く発生しなかった。したがって、塊を除去するために作業中断したり、作業効率が低下することもまったくなく、継続的に円滑な作業を実施することができた。 The anti-slip structure 550 of the present embodiment does not require a complicated configuration as in the prior art anti-slip tool, and can be completely functioned by only one chain as the connection structure 530. Moreover, there was no occurrence of lumps of snow, ice, etc. due to the connection method using a single chain. Therefore, the work was not interrupted to remove the lump, and the work efficiency was not lowered at all, and the smooth work could be carried out continuously.
クローラあたりの滑り止め構造装着個数について、さらに説明する。
左右各クローラに装着して十分な滑り止め効果を得るための装着個数について実験した。その結果、路面側に対して常に2箇所での滑り止めが機能するよう4個を装着したところ、滑り止め効果は必ずしも十分とはいえなかった。一方、各クローラに6個装着し、路面側に対して常に3箇所での滑り止めが機能するようにした場合には、十分な滑り止め効果を得ることができた。
The number of anti-slip structure mounted per crawler will be further described.
An experiment was conducted on the number of pieces mounted on the left and right crawlers to obtain a sufficient anti-slip effect. As a result, when four pieces were attached so that the anti-slip at two places always functions on the road surface side, the anti-slip effect was not necessarily sufficient. On the other hand, when six pieces were mounted on each crawler and the anti-slip function at three locations always functions on the road surface side, a sufficient anti-slip effect could be obtained.
したがって、本発明の滑り止め構造は、路面に対し3箇所以上で常に滑り止めが機能できるよう、クローラあたり6個以上を装着するようにすることが望ましい。また、各滑り止め構造間ができる限り均等(等間隔)となるよう装着することが望ましい。 Therefore, it is desirable to install six or more anti-slip structures of the present invention per crawler so that the anti-slip function can always function at three or more locations on the road surface. Further, it is desirable that the anti-slip structures are mounted as evenly as possible (equal intervals).
本発明の滑り止め構造は、クローラに対して確実・強固に係止、固定できることは上述のとおりであり、通常は、作業中にこれが脱落してしまうことは、まずない。しかしながら、悪路等における不慮の衝撃等により1個が脱落してしまうことはあり得る。実際に各クローラに6個ずつ装着した状態で相当程度の悪路を走行し、強制的に1個を脱落させてみたところ、その後の滑り止め効果は明らかに低下した。このことからも、各クローラあたり常に6個が装着されている状態の維持されることが望ましいと考えられた。 As described above, the anti-slip structure of the present invention can be securely and firmly locked and fixed to the crawler as described above, and it is unlikely that it will fall off during operation. However, it is possible for one to fall off due to an unexpected impact on a rough road or the like. Actually, when 6 pieces were attached to each crawler, the vehicle traveled on a considerably rough road, and when one was forcibly dropped, the subsequent anti-slip effect was clearly reduced. From this, it was considered that it was desirable to maintain a state in which 6 pieces were always attached to each crawler.
したがって、脱落の発生する場合を想定して、6個より多くの滑り止め構造を装着しておき、走行路面に対して常に3箇所以上において滑り止め機能が維持されるようにすることもできる。たとえば前掲図9等の実施例のように、各クローラに8個装着する方法である。なお、かかる目的のためには、たとえば7個であってもそれなりの補償作用を得られるが、各滑り止め構造をできるだけ均等に配置することで、より安定的な滑り止め効果を得たい観点からは、7個よりも8個とし、脱落の発生しない限りは常に、路面に対して4箇所での滑り止めが機能する装着方法が望ましい。もちろん、9個や10個以上であれば、より高度な滑り止め効果、脱落時を想定した安定性の向上が期待できるが、通常は実施例に示した片側8個ずつの装着方法で、申し分の無い効果を得ることができる。 Therefore, assuming that a dropout may occur, more than six anti-slip structures may be attached so that the anti-slip function is always maintained at three or more locations on the traveling road surface. For example, as in the embodiment shown in FIG. 9 and the like, it is a method of attaching eight to each crawler. For this purpose, even if there are seven, for example, a reasonable compensation action can be obtained, but from the viewpoint of obtaining a more stable anti-slip effect by arranging each anti-slip structure as evenly as possible. It is desirable to use a mounting method in which the number of slips is eight rather than seven and always prevents slipping at four locations on the road surface as long as no dropout occurs. Of course, if it is 9 or 10 or more, you can expect more advanced anti-slip effect and stability improvement assuming drop-off, but normally, the installation method of 8 on each side is fine, The effect without can be obtained.
本発明の車両用クローラの滑り止め構造、板状フック構造および車両用クローラの滑り止め方法によれば、泥濘・積雪・凍結その他のあらゆる悪路で、横滑り防止も含め、安定的かつ十分なクローラの滑り止め効果を得ることができる。しかも従来技術と比較して取り扱いも簡単であり、実用的である。したがって、農林業・土木・建設業分野、その他関連する全分野において、産業上利用性が高い発明である。 According to the vehicle crawler anti-slip structure, the plate-like hook structure, and the vehicle crawler anti-slip method of the present invention, stable and sufficient crawlers including prevention of skidding on any bad roads such as mud, snow, freezing, etc. The anti-slip effect can be obtained. In addition, it is easier to handle and practical than the prior art. Therefore, the invention is highly industrially applicable in the fields of agriculture, forestry, civil engineering, construction, and other related fields.
