【発明の詳細な説明】
本発明は、装軌車両の起動輪装置に関するもの
である。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a starting wheel device for a tracked vehicle.
第１図は装軌車両の概略正面図であり、車体ａ
に設けた起動輪ｂで履帯ｃを駆動して走行するよ
うに構成してある。 Figure 1 is a schematic front view of the tracked vehicle, with the vehicle body a
The vehicle is configured to run by driving a crawler track c using a starting wheel b provided at the front.
そして、起動輪ｂはけん引力を出すための回転
力F1（つまり、履帯ｃを駆動する回転荷重）とは
別に、不整地走行時に履帯ｃが走行面ｄに衝撃的
に接地する際等に突上げ荷重等の衝撃荷重F2を
受けることが多く、この衝撃荷重F2は車体ａに
伝播して車体各部及び車体に装着した機器の寿命
を低下すると同時に乗心地が著しく悪くなつてし
まう。 In addition to the rotational force F 1 for producing traction force (that is, the rotational load that drives the crawler track c), the starting wheel b is activated when the track c impacts the ground on the running surface d when traveling on rough terrain. The vehicle is often subjected to an impact load F 2 such as an uplift load, and this impact load F 2 propagates to the vehicle body a, shortening the life of each part of the vehicle body and equipment attached to the vehicle body, and at the same time significantly worsening the riding comfort.
そこで、駆動側起動輪部分にピンとゴムプツシ
ユを介して歯部を取付けた起動輪の構造とし、ゴ
ムプツシユにより突上げ荷重を吸収緩和できるよ
うにしたものが種々提案されているが、このよう
にすると回転荷重はピンとゴムプツシユで受ける
ことになるから、ピン、ゴムプツシユの寿命が短
かく耐久性が悪いとの不具合を有する。 Therefore, various proposals have been made for a starting wheel structure in which teeth are attached to the drive-side starting wheel portion via pins and rubber pushers, so that the thrust load can be absorbed and alleviated by the rubber pushers. Since the load is borne by the pin and rubber push, the pin and rubber push have short lifespans and poor durability.
本発明は、上記の事情に鑑みなされたものであ
り、その目的は、外部より負荷する衝撃荷重を吸
収緩和できると共に、大きな回転荷重に対する耐
久性を向上した装軌車両の起動輪装置を提供する
ことである。 The present invention has been made in view of the above circumstances, and its purpose is to provide a starting wheel device for a tracked vehicle that can absorb and alleviate externally applied impact loads and has improved durability against large rotational loads. That's true.

抜け出しを防止している。３６はスペーサであ
る。 Reference numeral 30 denotes a shaft for transmitting rotational force, first and second arc gears 31 and 32 are spline-fitted to both ends of the shaft 30, and first and second spherical surfaces are fitted to both end surfaces 30a and 30a of the shaft 30, respectively. Washishia 33 and 34 are bolts 35
The first and second spherical washers 33 and 34 prevent the first and second arc gears 31 and 32 from coming off. 36 is a spacer.
そして、第１・第２円弧歯車３１，３２は出力

３ａ，３４ａが支軸２１の外端面２１ａと蓋２８
の内端面２８ａにスベリ可能に接触している。 The first and second circular arc gears 31 and 32 mesh with the internal teeth 25 of the output side gear 18 and the internal teeth 27 of the cover body 26, respectively, to form a gear joint, and the first and second spherical washers 33, 34 spherical surface 3
3a and 34a are the outer end surface 21a of the support shaft 21 and the lid 28
It is slidably in contact with the inner end surface 28a of.
しかして、出力側歯車１８の回転は、内歯２
５、第１円弧歯車３１、軸３０、第２円弧歯車３
２、内歯２７、カバ体２６を介して起動輪外筒９
に伝達し、起動輪Ｂを軸受７を介してカバ４の筒
状部４ａの回りに回転駆動し、起動輪歯部１６で
履帯Ｃを駆動する。 Therefore, the rotation of the output side gear 18 is caused by the internal gear 2
5, first arc gear 31, shaft 30, second arc gear 3
2. Starting wheel outer cylinder 9 via inner teeth 27 and cover body 26
The starting wheel B is rotated around the cylindrical portion 4a of the cover 4 via the bearing 7, and the starting wheel tooth portion 16 drives the crawler belt C.
この時、起動輪歯部１６と出力側歯車１８とは
機械的に連結されているので、起動輪歯車１６の
回転力はクツシヨン材８に何ら作用しないから、
起動輪歯部１６に大きな回転力を伝達してもクツ
シヨン材８が破損することがなく、起動輪Ｂの回
転力を大きくできる。つまり、起動輪Ｂに大きな
回転荷重F1が作用してもクツシヨン材８が破損
しない。 At this time, since the starting wheel gear 16 and the output side gear 18 are mechanically connected, the rotational force of the starting wheel gear 16 does not act on the cushion material 8.
Even if a large rotational force is transmitted to the starting wheel tooth portion 16, the cushion material 8 is not damaged, and the rotational force of the starting wheel B can be increased. In other words, even if a large rotational load F1 is applied to the starting wheel B, the cushion material 8 will not be damaged.
また、履帯Ｃを介して突上げ荷重F2が作用す
ると、起動輪外筒９が上方に突き上げられ、クツ
シヨン材８（弾性材１２）が半径方向に圧縮変形
してカバ体２６がカバ４に対して上方に移動する
ので、内歯２７は内歯２５よりも上方に変位す
る。 Furthermore, when the thrust load F2 acts through the crawler belt C, the starting wheel outer cylinder 9 is thrust upward, the cushion material 8 (elastic material 12) is compressed and deformed in the radial direction, and the cover body 26 is pressed against the cover 4. On the other hand, since it moves upward, the internal teeth 27 are displaced upward compared to the internal teeth 25.
これにより、第１・第２円弧歯車３１，３２が
各内歯２５，２７に対して軸方向にすべりながら
揺動して軸３０が傾斜して、前記の変位を吸収す

球面３３ａ，３４ａどちらか一方が支軸外端面２
１ａ、カバ体内端面２８ａのどちらか一方に接触
して安定する。 As a result, the first and second circular arc gears 31 and 32 swing while sliding in the axial direction with respect to the respective internal teeth 25 and 27, and the shaft 30 is tilted to absorb the above-mentioned displacement. One of the spherical surfaces 33a and 34a of the second spherical washers 33 and 34 is the outer end surface 2 of the spindle.
1a or the cover inner end surface 28a for stability.
以上の動作により突上げ荷重F2を吸収緩和で
きる。 Through the above operations, the uplift load F 2 can be absorbed and alleviated.
また、クツシヨン材８のクツシヨン力以上の突
上げ荷重F2が作用した場合には、第３図に示す
ように、起動輪外筒９内向フランジ９′が起動輪
内筒６に当接して、それ以上の変位を防止してク
ツシヨン材８の破損を防止している。 Further, when an uplift load F 2 greater than the cushioning force of the cushion material 8 is applied, as shown in FIG. Further displacement is prevented to prevent damage to the cushion material 8.
なお、通常作業時の突上げ荷重F2はクツシヨ
ン材８のクツシヨン力よりも小さいので、内向フ
ランジ９′と起動輪内筒６とは離れている。 Incidentally, since the uplift load F 2 during normal operation is smaller than the cushioning force of the cushioning material 8, the inward flange 9' and the driving wheel inner cylinder 6 are separated from each other.
また、第１・第２円弧歯車３１，３２と内歯２
５，２７の噛合部には、前記歯車室イ内の潤滑油
が供給されて潤滑されると共に、その潤滑油がク
ツシヨン材８の弾性材１２に洩れることをシール
１５で防止している。 In addition, the first and second arc gears 31 and 32 and the internal teeth 2
The lubricating oil in the gear chamber I is supplied to the meshing portions 5 and 27, and the seal 15 prevents the lubricating oil from leaking into the elastic material 12 of the cushion material 8.
また、起動輪内筒６の外向フランジ６′は起動
輪外筒９内向フランジ９′とカバ体２６とで挾持
してあるので、起動輪歯部１６に作用する横荷重
を、前記部分で支持でき、クツシヨン材８をたわ
ませて起動輪歯部１６が軸方向に変位することを
防止できる。 In addition, since the outward flange 6' of the starting wheel inner cylinder 6 is sandwiched between the inward flange 9' of the starting wheel outer cylinder 9 and the cover body 26, the lateral load acting on the starting wheel teeth 16 is supported by the aforementioned portion. This makes it possible to prevent the starting wheel tooth portion 16 from being displaced in the axial direction due to the deflection of the cushion material 8.
本発明は以上の様になり、外部より負荷する衝
撃荷重をクツシヨン材８の弾性変形で吸収緩和で
きるから、車体１に衝撃荷重が伝播することが低
減されて、車体各部及び車体装着機器の寿命を向
上できると共に、乗心地を向上できる。 As described above, the present invention is capable of absorbing and relaxing the impact load applied from the outside through the elastic deformation of the cushion material 8, thereby reducing the propagation of the impact load to the vehicle body 1, thereby reducing the lifespan of each part of the vehicle body and the equipment mounted on the vehicle body. It is possible to improve not only the performance but also the riding comfort.
また、クツシヨン材８が弾性変形した時の起動
輪外筒９の出力側歯車１８に対する変位は、内歯
２７，２５と軸３０と第１・第２円弧歯車３２，
３１とで吸収でき、出力側歯車１８から起動輪Ｂ
への回転力伝達系統が破損することがない。 Further, when the cushion material 8 is elastically deformed, the displacement of the starting wheel outer cylinder 9 with respect to the output side gear 18 is as follows:
31, and from the output side gear 18 to the starting wheel B
The rotational power transmission system will not be damaged.
また、起動輪Ｂに負荷した回転荷重はクツシヨ
ン材には作用せずに直接出力側歯車１８に伝わる
から、クツシヨン材８が破損することがなく耐久
性が向上する。 Further, since the rotational load applied to the starting wheel B is directly transmitted to the output side gear 18 without acting on the cushion material, the cushion material 8 is not damaged and its durability is improved.
