【従来の技術】[Prior art]

無限軌道帯用の履帯は通常その沓面に、その長さ方向に沿って突出させた単数 または複数のラグを有する履板を多数のリンクにより、ブッシュおよびピンを介 して相互に無端状に連結した鉄製のものが用いられている。 ところが舗装路 面上の走行に際しては路面を著しく損傷するために、最近では図3および図4に 示したような各履板5の沓面にゴムやウレタン等の弾性材を使用した、取り付け 面に保型板2を有する弾性履板1を、鉄製履板5の4カ所のボルト穴6に対応す る位置にそれぞれボルトの頭部3aを埋設させたボルト3により、該ボルト3の 先端を鉄製履板5のボルト穴6から裏面側に突出させて、これを締め付け用袋ナ ット4により締め付け固定するようにしたものが多く用いられている。 Tracks for endless tracks are usually endlessly connected to each other through bushes and pins by means of a number of links on the shoe surface with a lug or lugs protruding along its length. The one made of connected iron is used. However, since the road surface is seriously damaged when traveling on a paved road surface, recently, as shown in FIGS. 3 and 4, an elastic material such as rubber or urethane is used for the shoe surface of each track 5 as a mounting surface. The elastic crawler plate 1 having the shape retention plate 2 is attached to the iron crawler plate 5 by bolts 3 in which heads 3a of the bolts are embedded at positions corresponding to the four bolt holes 6 of the iron crawler plate 5, respectively. It is often used that the iron crawler plate 5 is projected from the bolt hole 6 to the back surface side and is fixed by the tightening bag nut 4.

【考案が解決しようとする課題】[Problems to be solved by the device]

しかしながら、上記した締め付け固定手段による場合においては、ボルトの先 端を保護する必要上袋ナット4を用いて締め付けるために、これを鉄製履板5に 取り付けた場合、鉄製履板5の裏面側から突出する袋ナット4の突出高さはbと なり、袋ナット4の先端が鉄製履板5の裏面側に必要以上に突出し、その結果無 限軌道車両におけるフレームのギヤボックスとの間のスペースを狭めて砂利や土 砂類の噛み込みを生じやすくし、前記した袋ナットを損傷して弾性履板の取り外 しを困難にすることが多かった。 However, in the case of using the tightening and fixing means described above, since it is necessary to protect the front end of the bolt with the cap nut 4 for tightening, when this is attached to the iron shoe plate 5, from the back side of the iron shoe plate 5, The protruding height of the protruding cap nut 4 is b, and the tip of the cap nut 4 protrudes more than necessary on the back side of the iron shoe plate 5, resulting in a space between the frame and the gear box of the endless track vehicle. It was often narrowed to make it easier for gravel or sediment to be caught, and the cap nut was often damaged to make it difficult to remove the elastic shoe plate.

【0004】 またボルト3を突出させた弾性履板1は、その保管に際しても効率的な重ね合 わせが困難であるところから嵩ばりやすく、またボルト3の折れ曲がりやネジ山 の損傷を生じて使用できなくなるものも多い。Further, the elastic shoe plate 1 with the bolt 3 protruding is easily bulky because it is difficult to stack them efficiently even during storage, and the bending of the bolt 3 and the damage of the screw thread are caused to be used. There are many things that cannot be done.

【課題を解決するための手段】[Means for Solving the Problems]

本考案は上記した従来技術における課題を解決し、無限軌道車両への取り付け 時における鉄製履板の裏面での、取り付け手段の必要以上の突出をなくすととも に、弾性履板の保管性を向上させたものであって、具体的には鉄製履板の沓面に 重合されるところの弾性履板であって、該弾性履板の取り付け面側における、前 記した鉄製履板の取り付けボルト穴に対応する位置に、取り付け用のナットが埋 設されており、鉄製履板の裏側から通されたボルトの先端を上記ナットに螺入さ せて一体に取り付けるようにしたことを特徴とする無限軌道帯用弾性履板に関す る。 The present invention solves the above-mentioned problems in the prior art, and eliminates unnecessary protrusion of the attachment means on the back surface of the iron track plate when mounting it on a tracked vehicle, and improves the storability of the elastic track plate. Specifically, it is an elastic shoe plate that is overlapped on the recess surface of the iron shoe plate, and the mounting bolt hole of the iron shoe plate described above on the attachment surface side of the elastic shoe plate. The mounting nut is embedded in the position corresponding to the infinite number, and the tip of the bolt passed from the back side of the iron shoe plate is screwed into the nut to be mounted integrally. This relates to elastic track plates for orbital zones.

【実施例】【Example】

以下において本考案の具体的な内容を図の実施例をもとに説明すると、11は 弾性履板、13は袋ナットを示す。 弾性履板11はゴム、あるいはウレタン樹 脂等、ある程度柔軟性のある材質からなり、これを鉄製履板15の沓面の凹凸形 状にあわせて成型し、しかも鉄製履板15に設けられているボルト穴16に対応 する位置にボルト穴を開設した鉄製の保型板12に、接着もしくは焼き付け等の 手段により一体に構成される。 The concrete contents of the present invention will be described below with reference to the embodiments shown in the drawings. The elastic track plate 11 is made of a material having flexibility to some extent, such as rubber or urethane resin. The elastic track plate 11 is molded according to the uneven shape of the shoe surface of the iron track plate 15 and is provided on the iron track plate 15. It is integrally configured by means such as bonding or baking to a steel mold plate 12 having bolt holes formed at positions corresponding to the bolt holes 16 formed therein.

【0008】 袋ナット13は、上記した保型板12の裏側において、該保型板12に形成し た各ボルト穴12aに対応させて、しかも弾性履板11の取り付け面側に開口部 を望ませた状態において埋設されており、その結果弾性履板の取り付け面側は平 坦で全く突出部がみられない。 なお本案の実施例においては弾性履板11内に 袋ナット13を埋設させるようにしたが、かならずしも袋状のナットである必要 はなく、通常のナットを埋設するようにしてもよい。The cap nut 13 has an opening on the back side of the mold retaining plate 12 corresponding to each bolt hole 12 a formed in the mold retaining plate 12, and has an opening on the mounting surface side of the elastic shoe plate 11. It is buried in the empty state, and as a result, the mounting surface side of the elastic track plate is flat and no protrusion is seen at all. Although the cap nut 13 is embedded in the elastic shoe plate 11 in the embodiment of the present invention, the cap nut is not always required to be a bag nut, and a normal nut may be embedded.

【0009】 しかるにこれを鉄製履板15の沓面に、その取り付けボルト穴12aを鉄製履 板15のボルト穴16に対応させて取り付け面を重ね合わせ、さらに鉄製履板1 5の裏面側よりボルト14を挿通させて、その先端を弾性履板11側の袋ナット 13に螺入させて取り付ける。 したがって鉄製履板15に取り付けた状態にお ける、鉄製履板15から突出する締め付けボルト14の頭部の突出高さはaとな り、前記した従来例(図4)の場合に比してb>aとなり、その結果無限軌道車 両におけるフレームのギヤボックスとの間のスペースを広く確保して砂利や土砂 類の噛み込みによるボルト14の損傷発生の恐れをなくすことができる。[0009] However, the mounting surface of the iron track plate 15 is overlapped with the mounting bolt hole 12a of the iron track plate 15 so as to correspond to the bolt hole 16 of the iron track plate 15. 14 is inserted, and the tip is screwed into the cap nut 13 on the elastic shoe plate 11 side to be attached. Therefore, the head height of the tightening bolt 14 protruding from the iron shoe plate 15 when attached to the iron shoe plate 15 is a, which is larger than that of the conventional example (FIG. 4) described above. As a result, b> a is established, and as a result, a wide space can be secured between the frame and the gear box of the tracked vehicle, and the risk of damage to the bolt 14 due to biting of gravel or earth and sand can be eliminated.

【考案の効果】[Effect of device]

本考案は上記した通り、鉄製履板の沓面に重合されるところの弾性履板であっ て、該弾性履板の取り付け面側における、前記した鉄製履板の取り付けボルト穴 に対応する位置に、取り付け用のナットが埋設されており、鉄製履板の裏側から 通されたボルトの先端を上記ナットに螺入させて一体に取り付けるようにしたた めに、鉄製履板の裏面側における締め付け手段はナットではなく通常のボルトで よく、したがってこれを鉄製履板に取り付けた場合、鉄製履板から裏面側に突出 する締め付けボルトの突出高さを低く押さえることができ、その結果無限軌道車 両におけるフレームのギヤボックスとの間のスペースを十分に確保できるので砂 利や土砂類の噛み込みを生じ、またこれによりボルトを損傷したりすることがな い。 As described above, the present invention is an elastic shoe plate that is overlapped with the wheel surface of the iron shoe plate, and at the position corresponding to the mounting bolt hole of the iron shoe plate on the mounting surface side of the elastic shoe plate. , The mounting nut is embedded, and the tip of the bolt passed from the back side of the iron shoe plate is screwed into the nut so that it can be integrally attached. Can be a normal bolt instead of a nut, and therefore, when it is attached to the iron track, the protruding height of the tightening bolt protruding from the iron track to the back side can be kept low, and as a result, in the tracked vehicle. A sufficient space between the frame and the gear box can be secured so that gravel and sediment will not be caught, and this will not damage the bolt.

【0011】 また弾性履板には、その取り付け面側に取り付け用のボルトを突出させていな いので重ね合わせが可能となり、保管に際しても嵩ばることがないばかりでなく 、ボルト3の折れ曲がりやネジ山の損傷による使用不能、あるいは鉄製履板から の取り外し性の困難を招くといったような不都合を解消することができる。[0011] Furthermore, since the elastic shoe plate does not have mounting bolts protruding from the mounting surface side, it is possible to stack them, and not only does it become bulky during storage, but also the bending and screwing of the bolts 3 are possible. Inconveniences such as unusability due to damage to the mountain or difficulty in detachability from the iron shoe plate can be eliminated.
