【産業上の利用分野】[Industrial applications]

本考案は装軌式車両の上転輪に係り、特に履帯リンクと上転輪が接触時に、衝 突して発生する騒音の低減を図った装軌式車両の上転輪騒音低減装置に関する。 The present invention relates to an upper wheel of a tracked vehicle, and more particularly to an upper wheel noise reduction device of a tracked vehicle for reducing noise generated by collision when a crawler belt link and an upper wheel contact each other.

【0002】[0002]

【従来の技術】[Prior art]

従来から例えば図3に示すブルド−ザ等の装軌式車両21においては、走行用 として足回り装置22がある。この足回り装置22には前に遊動輪23,後に起 動輪24があって、その両者の回りに履帯25が巻かれており、遊動輪23と起 動輪24との間にはトラックフレ−ム26の上下に設けた転輪27,28があっ て移動する履帯25を支持している。このうち上転輪27について見ると一部詳 細を図4に示すように履帯25の硬いリンク踏み面(ゴム履帯の場合は芯金)2 5aと、トラックフレ−ム26の上面に固定支持された上転輪27の踏み面27 aとが直接衝突し合い、これが起振源となって走行騒音を発生させている。 Conventionally, in a tracked vehicle 21 such as a bulldozer shown in FIG. 3, there is an undercarriage device 22 for traveling. The undercarriage device 22 has an idler wheel 23 in front and an idler wheel 24 in the rear, and a crawler belt 25 is wound around both of them, and a track frame is provided between the idler wheel 23 and the idler wheel 24. Wheels 27 and 28 provided above and below 26 support the moving crawler belt 25. As for the upper roller 27, some details are shown in FIG. 4, and fixedly supported on the hard link tread surface (core metal in the case of rubber track) 25a of the track 25 and the upper surface of the track frame 26. The tread surface 27a of the upper rolling wheel 27 thus directly collided with each other, which acts as a vibration source to generate running noise.

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

このような走行騒音の対策として、これまでに種々の発明や考案がなされてき ている。例えば特表平4−500789号公報や実開平4−56588号公報に 開示されているように、何れも転輪踏み面に緩衝材を貼ることにより騒音を低減 させるようにしたものであり、緩衝材としては非金属の弾性体を用いてリンクと 直接衝突させるために耐久性がなく、したがって未だ実用化されていないのが現 状である。 As measures against such running noise, various inventions and inventions have been made so far. For example, as disclosed in Japanese Patent Publication No. 4-500789 and Japanese Utility Model Laid-Open No. 4-56888, noise is reduced by attaching a cushioning material to the tread of the rolling wheels. As a material, a non-metallic elastic body is used to directly collide with the link, so that the material has no durability, and thus is not yet practically used.

【0004】 本考案はこれに鑑み、緩衝材としての弾性体の耐久性の向上を図った装軌式車 両の上転輪騒音低減装置を提供して従来技術の持つ欠点の解消を図ることを目的 としてなされたものである。In view of this, the present invention intends to solve the drawbacks of the prior art by providing an upper wheel noise reducing device for a tracked vehicle with improved durability of an elastic body as a cushioning material. It was made for the purpose.

【0005】[0005]

【課題を解決するための手段】 上記目的を達成するため本考案の請求項1は上転輪の転動面にワイヤロ−プを 螺旋状に巻付けて、踏み面を形成し、該ワイヤロ−プの端部を該上転輪の鍔部の 外側でプレ−トにより挟持したことを特徴とし、請求項2は上転輪の転動面のラ ジアル方向に適宜間隔のある金属リングを嵌め込み、該金属リングと転動面との 間に弾性体を加硫成形して一体に固着して踏み面を形成すると共に、該上転輪の 両端面には前記金属リングの外れを防止するプレ−トを設けたことを特徴とする 。In order to achieve the above object, the first aspect of the present invention is that the wire rope is spirally wound around the rolling surface of the upper roller to form a tread surface. The end portion of the upper rolling wheel is sandwiched by a plate outside the flange portion of the upper rolling wheel, and the second aspect of the present invention is to insert a metal ring with an appropriate interval in the radial direction of the rolling surface of the upper rolling wheel. An elastic body is vulcanized and molded between the metal ring and the rolling surface to integrally fix the metal ring to form a tread surface, and at the both end surfaces of the upper rolling wheel, a pre-prevention member for preventing the metal ring from coming off is formed. -It is characterized in that it is provided.

【0006】[0006]

【作用】[Action]

上記構成によれば、請求項1ではワイヤロ−プの円形断面が履帯リンクとの衝 突により変形し易いために緩衝効果が大きくなり、また、請求項2では緩衝効果 は弾性体が持ち、弾性体の摩耗防止は金属リングが持つことになる。 According to the above structure, in the first aspect, the circular cross section of the wire rope is easily deformed by the collision with the crawler belt link, so that the cushioning effect becomes large. The metal ring has a body wear protection.

【実施例】【Example】

図1は本考案の請求項1にかかる装軌式車両の上転輪騒音低減装置の一実施例 を示し、図2は請求項2にかかる装軌式車両の上転輪騒音低減装置の一実施例を 示す。 FIG. 1 shows an embodiment of an upper wheel noise reduction device for a tracked vehicle according to claim 1 of the present invention, and FIG. 2 shows an upper wheel noise reduction device for a tracked vehicle according to claim 2. An example is shown.

【0008】 以下、本考案の請求項1を図1に示す実施例を参照して説明する。請求項1は 上転輪1の転動面2にワイヤロ−プ3を螺旋状に巻付けて、踏み面4を形成し、 該ワイヤロ−プ3の端部を該上転輪1の鍔部1aの外側でプレ−ト5により挟持 したもので構成されている。Hereinafter, claim 1 of the present invention will be described with reference to the embodiment shown in FIG. According to a first aspect of the present invention, a wire rope 3 is spirally wound around a rolling surface 2 of an upper rolling wheel 1 to form a tread surface 4, and an end portion of the wire rope 3 is provided with a flange portion of the upper rolling wheel 1. It is configured by being sandwiched by a plate 5 on the outside of 1a.

【0009】 上転輪1の転動面2の両端には鍔部1aが形成されて、踏み面4となるように 転動面2に巻かれたワイヤロ−プ3の両端部は鍔部1aの内外側に貫通して設け られた穴を通して外側に折り曲げられ、ワイヤロ−プ3を外側から鍔部1aとの 間に挟み込むように湾曲して形成されたプレ−ト5により位置決めされる。そし てプレ−ト5の両端においてボルト6により締め付けて固着するようにしたもの である。Collar portions 1 a are formed at both ends of the rolling surface 2 of the upper rolling wheel 1, and both ends of the wire rope 3 wound around the rolling surface 2 so as to become the tread surface 4 have collar portions 1 a. It is bent outward through a hole penetrating inward and outward, and is positioned by a plate 5 formed so as to be curved so that the wire rope 3 is sandwiched between the wire rope 3 and the collar portion 1a. Then, both ends of the plate 5 are fastened with bolts 6 so as to be fixed.

【0010】 つぎに作用を説明する。細い鋼線を撚って作られたワイヤロ−プ3は、その円 形断面が外力を受けると変形し易いため、緩衝効果が大きくなる。したがってこ れを転動面2に巻付けることによって上転輪1の踏み面4が形成され、この踏み 面4が履帯リンクと衝突した場合の衝撃を緩衝することができ、衝突音が小さく なる。すなわち小さい面積で叩かれれば衝撃音も小さいことになる。Next, the operation will be described. The wire rope 3 made by twisting a thin steel wire is easily deformed when its circular cross section is subjected to an external force, so that the cushioning effect is increased. Therefore, by winding this around the rolling surface 2, the tread surface 4 of the upper rolling wheel 1 is formed, and the shock when the tread surface 4 collides with the crawler belt link can be buffered, and the collision noise is reduced. . That is, the impact sound will be small if it is hit with a small area.

【0011】 本考案の請求項2は図2に示すように上転輪7の転動面8のラジアル方向に適 宜間隔のある金属リング9を嵌め込み、該金属リング9と転動面8との間に弾性 体10を加硫成形して一体に固着して踏み面11を形成すると共に、該上転輪7 の両端面には前記金属リング9の外れを防止するプレ−ト12を設けたもので構 成されている。According to the second aspect of the present invention, as shown in FIG. 2, a metal ring 9 having an appropriate space is fitted in the radial direction of the rolling surface 8 of the upper rolling wheel 7, and the metal ring 9 and the rolling surface 8 are connected to each other. An elastic body 10 is vulcanized and fixed between the two to form a tread 11, and a plate 12 for preventing the metal ring 9 from coming off is provided on both end faces of the upper roller 7. It is made up of food.

【0012】 踏み面11は図示のように履帯リンク13と接触する部分にのみ金属リング9 が嵌込まれている。そして金属リング9のない中央部分は弾性体10の逃げ溝1 4となっている。金属リング9はの材質はステンレス、または、鋼で作られ、弾 性体10の材質はゴムやウレタンなどで作られている。プレ−ト12は踏み面1 1が履帯リンク13と接触したとき、金属リング9に働くスラスト力による外れ を防止するためのもので上転輪7に複数本のボルト15により固着されている。As shown in the figure, the tread 11 is fitted with the metal ring 9 only at the portion in contact with the crawler belt link 13. The central portion without the metal ring 9 serves as a relief groove 14 for the elastic body 10. The metal ring 9 is made of stainless steel or steel, and the elastic body 10 is made of rubber or urethane. The plate 12 is used to prevent the tread 11 from coming off due to the thrust force acting on the metal ring 9 when the tread 11 comes into contact with the crawler belt link 13, and is fixed to the upper roller 7 by a plurality of bolts 15.

【0013】 つぎに作用を説明する。金属リング9は弾性体10の表面の保護が目的であり 、履帯リンク13と上転輪7の踏み面11との緩衝は弾性体10が受け持つ。し たがって従来のように弾性体の表面を表面積の大きい金属プレ−トで覆うと、プ レ−ト表面が音の放射面となって音が下がらなかったが、本考案のように分割し た金属リング9を設けることにより放射面積を小さくでき、しかも金属リング9 間同士の摩擦により音の減衰を速くし、騒音の低減効果も高められる。なお、金 属リングの代わりに請求項1に示したワイヤロ−プを用いても同様の効果が得ら れることは云うまでもない。The operation will be described below. The metal ring 9 is intended to protect the surface of the elastic body 10, and the elastic body 10 takes charge of cushioning the crawler belt link 13 and the tread 11 of the upper wheel 7. Therefore, when the surface of the elastic body was covered with a metal plate having a large surface area as in the conventional case, the plate surface did not serve as a sound emitting surface and the sound did not fall, but it was divided as in the present invention. By providing the metal ring 9, the radiation area can be reduced, and the friction between the metal rings 9 can accelerate the sound attenuation and enhance the noise reduction effect. Needless to say, the same effect can be obtained by using the wire rope shown in claim 1 instead of the metal ring.

【考案の効果】[Effect of device]

以上説明したように本考案は、請求項1において上転輪の転動面にワイヤロ− プを螺旋状に巻付けて、踏み面を形成し、該ワイヤロ−プの端部を該上転輪の鍔 部の外側でプレ−トにより挟持し、請求項2では上転輪の転動面のラジアル方向 に適宜間隔のある金属リングを嵌め込み、該金属リングと転動面との間に弾性体 を加硫成形して一体に固着して踏み面を形成すると共に、該上転輪の両端面には 前記金属リングの外れを防止するプレ−トを設けたから、請求項1では緩衝材と してワイヤロ−プまたは金属リングを用いることにより騒音の低減は云うまでも なく、また、摩耗したときの交換が容易となる。請求項2では弾性体の保護とし てワイヤロ−プまたは金属リングを用いると、弾性体の耐久性が向上し、さらに 弾性体が大きな緩衝材となっていることでワイヤロ−プまたは金属リングの摩耗 を少なくすることができる。 As described above, according to the present invention, in claim 1, the wire rope is spirally wound around the rolling surface of the upper rolling wheel to form a tread, and the end portion of the wire rope is connected to the upper rolling wheel. The plate is sandwiched by a plate on the outside of the collar portion, and in claim 2, a metal ring having an appropriate interval in the radial direction of the rolling surface of the upper rolling wheel is fitted, and an elastic body is provided between the metal ring and the rolling surface. The plate is formed by vulcanization and integrally fixed to form a tread surface, and plates for preventing the metal ring from coming off are provided on both end surfaces of the upper roller. Needless to say, noise can be reduced by using a wire rope or a metal ring, and replacement when worn is easy. When the wire rope or the metal ring is used as the protection of the elastic body in claim 2, the durability of the elastic body is improved, and the wear of the wire rope or the metal ring is increased because the elastic body serves as a large cushioning material. Can be reduced.
