【考案が解決しようとする課題】 [Challenges devised to be Solved]

このような踏面が平胆等に形成したものは、車輌走行時に走行面との接触面が 大きく、旋回時の抵抗が大きくなる。 That such tread is formed on the flat bile or the like, a large contact surface with the running surface during vehicle running, resistance increases during cornering. 小型の車輌の場合は、車輌が比較的軽量で 、かつ、小型なので、履帯用パッドの欠けも少なくさほど問題にはならなかった 。 For small vehicles, vehicle is relatively lightweight, and so compact, had the missing also less serious problem of the track pad. しかし、車輌が中型、大型で、それにつれ大型となった履板に取付る履帯用パ ッドは、比例して平坦状を中型又は大型にすると、接地面積がより多くなり、安 定ではあるが、旋回時に抵抗が大で両端部の角部の欠けが生じ、更に、ピッチン グが生じ、機体が飛び跳ねるという問題があらわれる。 However, the vehicle is medium-sized, large, install them crawler belt Pas head to the track shoe it became that as the large-sized, when the middle- or large-sized flat shape proportionally, becomes more and more ground area, there is a Jo An but the resistance at the time of turning is caused chipping corners of both ends at large, further, it causes pitching grayed, aircraft problem that jumping appears.

【0004】 又、弾性部材を一様に平坦にすると、ゴム量が増大し、中型や大型の車輌の場 合、全体的に膨大な量となり、ゴム材料を多く必要とした。 [0004] Also, the uniformly flattening the elastic member, rubber increases or if medium-sized or large vehicles, it is generally huge amount and many require rubber material.

【0005】 更に、弾性部材を一様に平坦にすると、中型や大型の車輌の場合、全体的に重 量が増大し、車輌総重量が増し、作業の機敏性に欠けるという問題があった。 Furthermore, the uniform flattening the elastic member, the case of medium-sized and large-sized vehicles, overall weight increases or vehicle gross weight is increased, there is a problem of lack of agility work.

【0006】 本考案は、このような欠点を解消するためになされたもので、車輌が中型又は 大型で、それにつれ履帯パッドも中型又は大型となっても、従来の安定を維持し つつピッチングが生じず、経済的な耐久性のある履帯用パッドを提供することを 目的とする。 [0006] The present invention has been made in order to solve such a drawback, vehicle is in middle or large-sized, even if it As the track pad also medium- or large-sized, pitching while maintaining conventional stable It occurs not, and an object thereof is to provide a crawler belt pad with economic durability.

【課題を解決するための手段】 In order to solve the problems]

上記目的を達成するために、本考案の履帯用パッドは、中央ラグを有する履板 の踏面に沿うよう形成された補強部材と、補強部材の上面に固着し平坦な踏面を 形成した弾性部材と、補強部材の両端部側で履板に装着するためのボルトとより なる履帯用パッドにおいて、弾性部材の踏面側に、長手方向に左右対称で全幅に 亘る2つの凹部を形成して、中央部と両端部との3つの独立した踏面を形成した 。 To achieve the above object, track pad of the present invention includes a reinforcing member formed as along the tread surface of the crawler plate having a central lug, and fixed to the upper surface of the reinforcing member to form a flat tread elastic member , the more the bolt for mounting the track shoe at both ends of the reinforcing member in the crawler belt pad, the tread side of the elastic member, to form two recesses over the entire width in the left-right symmetry in the longitudinal direction, the central portion that form three independent tread both ends.

【0008】 2つの凹部を形成し、中央部と両端部に3つの独立した平坦な踏面を形成した ので、踏面が小型となって、通常の走行の安定を維持しつつ、車輌旋回時の抵抗 を小さく、ピッチングを少なくすることができる。 [0008] forming two recesses, so to form a flat tread with three independent in the central portion and both end portions, tread surface becomes small, while maintaining the stability of the normal running resistance at the time of vehicle turning the small, it is possible to reduce the pitching.

【0009】 また、凹部を形成したので、ゴムパッド量が節約できる。 Further, since a recess, it can be saved rubber pad weight.

【0010】 車輌の総重量軽減に貢献するとともに、車輌の走行がスムーズとなる。 [0010] as well as contributing to the total weight reduction of the vehicle, the vehicle is running is smooth.

【考案の実施の形態】 [Embodiment of the invention]

考案の実施の形態を実施例にもとづき図1乃至図4を用いて説明する。 An embodiment of the invention with reference to based FIGS. 1 to 4 in Examples will be described. 履帯用パッドは、車輌の進行方向に対し、直交した複数の長尺の各履板上に装 着するもので、履板に沿うように長尺の略矩形で、補強部材1と、補強部材の上 面に固着する弾性部材であるゴムパッド2と、履板5に履帯用パッドを装着させ るためのボルト4とからなる。 Crawler belt pad to the traveling direction of the vehicle, intended to instrumentation wear on each track shoe of the plurality of elongated orthogonal, substantially rectangular elongated along the track shoe, and the reinforcing member 1, the reinforcement member a rubber pad 2 is an elastic member for fixing to the upper surface of, consisting bolt 4 which in order to attach the track pad to the track shoe 5.

【0012】 補強部材1は、履板5の踏面に合致するように、履板の中央ラグ5aと合致す る中央ラグ挿入部1aを有し、前後ラグ5b、5b内に合致するように断面が略 W字型に形成されている。 [0012] reinforcing member 1, so as to match the treads of the crawler plate 5 has a central lug insertion portion 1a you match the central lug 5a of the track shoe, cross-section to match the longitudinal lugs 5b, the 5b There is formed into a substantially W-shape.

【0013】 補強部材1の上面に、加硫接着等の手段にて補強部材1に一体的に結合した弾 性部材であるゴムパッド2があり、このゴムパッド2は、上面の踏面である接地 面は、長手方向に左右対称で全幅に亘って緩やかなカーブの2つの凹部2c、2 cを形成して、中央部2aと両端部2b、2bに、所定間隔(凹部分)をあけて 独立の3つの平坦な踏面を形成する。 [0013] the upper surface of the reinforcing member 1, there is a rubber pad 2 is elastic member coupled integrally to the reinforcing member 1 by means such as vulcanization adhesion, the rubber pad 2, the ground plane is a tread upper surface , to form two recesses 2c, 2 c of the gentle curve over the entire width in the left-right symmetry in the longitudinal direction, the central portion 2a and end portions 2b, the 2b, independently at predetermined intervals (concave portion) 3 One of the form a flat tread. 又、両側2d、2dは履板の前後ラグ5b 、5b側に突出し、下面が前後ラグ5b、5b上面と当接する。 Further, both sides 2d, 2d are front and rear lugs 5b of the track shoe protrudes 5b side, the lower surface front and rear lugs 5b, 5b top and abuts. 中央部2aと両 端部2b、2bとの踏面の総接地面積が、中型、大型の履帯用パッドであっても 小型又はの履帯用パッドと略同等の接地面積に縮小して形成している。 Central portion 2a and the both end portions 2b, the total contact area of ​​the tread and 2b are medium-sized, even in the crawler belt pad large is formed by reducing the size or tracks pad and ground contact area substantially equal to . この実施例では、ゴムパッド2の厚みは、弾性力を有するには、30ミリ以上 を必要とする。 In this embodiment, the thickness of the rubber pad 2, the has a resilient force, requires more than 30 mm. 実施例では、中型、大型にするとゴム材が多く、重量が増大してしまうので、 踏面までのゴム厚をできるだけ薄くしている。 In an embodiment, medium, when a large number rubber, the weight increases, and as thin as possible a rubber thickness of up to tread. しかも、通常走行時は非接触であ る凹部2cも、凹凸の激しい砂利等の現場で、凹部2cが接触した場合にでもあ る程度弾性力が作用するように30ミリの厚みを保持させてある。 Moreover, during normal running recess 2c Ru contactless der also in the field of heavy gravel or the like irregularities, by holding the thickness of 30 millimeters to act Demoa Ru extent elastic force when the recess 2c is in contact is there. 従って、踏面 と凹部の上面のクリアランスは少なく、その間は緩やかなカーブにしてある。 Therefore, the clearance of the upper surface of the tread and the recess is small, during which are the gentle curve. 勿論、非接触部の凹部の深さは、弾性力を無視すれば、深くすることは可能で ある。 Of course, the depth of the concave portion of the non-contact portion, neglecting elastic force, it is possible to deeply possible. この場合、ゴム材は大幅に節約できる。 In this case, the rubber material can be greatly saved. 両端の平坦な端部2b、2bは、車輌の通常走行を安定させる働きがある。 Flat end 2b at both ends, 2b may serve to stabilize the normal running of the vehicle. 又 旋回時に集中して荷重を受け易く強度を必要とする部位である。 Also a site requiring easy strength under load concentrated on during turning. 従って、本考案のゴムパッドの踏面である両端部は通常の肉圧にしている。 Accordingly, both end portions is a tread rubber pad of the present invention are the usual meat pressure. 尚 、実施例では、全踏面は、平面全体の略1/2に形成している。 In the embodiment, the entire tread surface is formed on substantially half of the overall plan. 凹部の深さもゴム厚があれば、更に深くすることが可能である。 If the rubber thickness also the depth of the recess, it is possible to further deeply.

【考案の効果】 本考案は、上記の如く構成されるで、次に記載する効果を奏する。 [Effect of the invention The present invention is, in the above as configured, an effect that will be described.

【0015】 中型、大型の履帯用ゴムパッドであっても、接地面を減らしたので、旋回時の ピッチングが発生しにくい。 [0015] The medium-sized, even in the crawler belt rubber pad of large, since reduced the ground plane, pitching is less likely to occur at the time of turning.

【0016】 車輌走行時、又は作業中におけるきしみ音の発生が防げる。 [0016] when the vehicle running, or the occurrence of creaking sound in the work prevented.

【0017】 ゴムパッドの踏面に凹部を形成したので、ゴム材料が軽減し、材料費が減り、 コストに反映する。 [0017] Since the formation of the recesses in the tread surface of the rubber pad, rubber material is reduced, reduces material costs, reflected in the cost. 即ち、エコノミータイプの履帯用パッドといえる。 In other words, it can be said that the track pad of Economy Type.

【0018】 凹部による材料軽減で重量が減り、中型、大型車輌の走行操作がスムーズとな る。 [0018] reduces the weight of a material Mitigation recess, medium-sized, traveling operation of a large vehicle is ing and smooth.

【0019】 中型、大型の履帯用パッドとはいえ、軽量になるので、車輌への取り付け作業 が楽になり、取り付け作業の向上につながる。 [0019] The medium-sized, although the large track pad of, since the lightweight, mounting work of the vehicle is easier, leading to the improvement of the installation work.
