Description

本発明は、車両駆動装置に関する。 The present invention relates to a vehicle drive device.

鉄道による貨物輸送は、自動車、船、航空機などのその他の輸送手段に比べＣＯ２など環境負荷となるガスの排出量が少なく、トラックによる都市部の渋滞緩和にも効果的であり、さらには、車両用駆動装置の発展により貨物輸送も高速化されますます注目されている。機関車は一度に大量の貨物を牽引輸送するため、車両駆動装置の一部である機関車用回転電機は、一般の電車用回転電機に比べ大型・大容量となる。また、機関車の床下は様々な電気機器が配置され、回転電機および歯車箱を構成するスペースは狭いため、一般の電車とは駆動装置の形態が異なる。 Freight transportation by rail, car, ship, emit less other a CO 2 environmental impact compared to vehicle gas, such as an aircraft, it is also effective to alleviate traffic congestion in urban areas due to the track, and further, With the development of vehicle drive devices, freight transportation is also getting faster, and it is attracting attention. Since a locomotive pulls and transports a large amount of cargo at a time, a locomotive rotating electrical machine that is a part of a vehicle drive device has a large size and a large capacity compared to a general electric rotating machine for trains. Various electric devices are arranged under the floor of the locomotive, and the space constituting the rotating electric machine and the gear box is narrow. Therefore, the form of the driving device is different from that of a general train.

従来の駆動装置について図を参照し詳細に説明する。図７は、従来の駆動装置の構成図である。図８は、駆動装置の歯車箱の正面図である。図９は、図８のＡ−Ａ断面図である。図１０は、図８のＢ−Ｂ断面図である。   A conventional driving apparatus will be described in detail with reference to the drawings. FIG. 7 is a configuration diagram of a conventional drive device. FIG. 8 is a front view of the gear box of the drive device. 9 is a cross-sectional view taken along the line AA in FIG. 10 is a cross-sectional view taken along the line BB in FIG.

従来の駆動装置において、回転電機３の回転子軸９の先端にはピニオン２が取付いており、ギヤ５の取付いた車輪軸７を介し車輪４に動力が伝達される。回転電機３は車輪軸７を覆うサスペンションチューブ８で支持されている。歯車箱１は、ピニオン２とギヤ５を箱内に構成する。潤滑剤には潤滑剤が使用されている。良い潤滑状態を保つためには、潤滑剤が変質することなく十分に機能を果たすことが重要である。潤滑剤は異物混入により変質するため、歯車と共に歯車箱の中に密閉される必要がある。 In the conventional drive device, the pinion 2 is attached to the tip of the rotor shaft 9 of the rotating electrical machine 3, and power is transmitted to the wheel 4 through the wheel shaft 7 to which the gear 5 is attached. The rotating electrical machine 3 is supported by a suspension tube 8 that covers the wheel shaft 7. The gear box 1 comprises a pinion 2 and a gear 5 in the box. A lubricant is used as the lubricant. In order to maintain a good lubrication state, it is important that the lubricant functions sufficiently without deterioration. Since the lubricant changes in quality due to foreign matter mixed in, it must be sealed in the gear box together with the gear.

従来の駆動装置において、歯車箱１は、２分割型で組立てられる。図８，図９，図１０に示すように、分割された歯車箱１の合わせ面１３は、組立後、はかま（合わせ目）１２が覆いかぶさりシールされるが、車輪軸の摺動部およびギヤボス１０摺動部はパッキン６でシールされている。
実開平０６−７４５５１号公報 In the conventional driving device, the gear box 1 is assembled in a two-part type. As shown in FIGS. 8, 9, and 10, the mating surface 13 of the divided gear box 1 is covered and sealed with a hook (joint) 12 after assembly. 10 sliding parts are sealed with packing 6.
Japanese Utility Model Publication No. 06-74551

しかし、前記パッキン６だけのシールでは不完全であり、これまでに歯車箱１内の潤滑剤が外部に漏れる問題が発生した。対策として、パッキン６を並列に２段並べてシールを強化した。パッキン６をさらに並べれば、効果は得られることが予想されるが、機関車の台車枠内は狭いスペースしか確保されず、困難である。そこで、図１１に示すように、並列したパッキン６ａとパッキン６ｂの間に、潤滑剤を戻す穴１５を設けることで、潤滑剤は歯車箱の外に漏れること無く、図１１の矢印のように流れ、歯車箱１内へ戻り歯車箱１外への漏れの軽減が可能となった。穴１５を設けたことで、潤滑剤の歯車箱１内から外への漏れは軽減されたが、今度は、歯車箱１の外からの水浸入が多発した。 However, the seal with only the packing 6 is incomplete, and there has been a problem that the lubricant in the gear box 1 leaks to the outside. As a countermeasure, the seals were reinforced by arranging two packings 6 in parallel. If the packings 6 are further arranged, the effect is expected to be obtained, but it is difficult because only a narrow space is secured in the bogie frame of the locomotive. Therefore, as shown in FIG. 11, by providing a hole 15 for returning the lubricant between the parallel packing 6a and packing 6b, the lubricant does not leak out of the gear box, as shown by the arrow in FIG. The flow returned to the inside of the gear box 1 and the leakage to the outside of the gear box 1 could be reduced. By providing the holes 15, leakage of the lubricant from the inside of the gear box 1 to the outside was reduced, but this time, water intrusion from the outside of the gear box 1 occurred frequently.

特に、降雪地区を走行する機関車は歯車箱１には雪が大量に積もり、図１２に示すように、積雪が融解して、歯車箱１の側壁を伝ってパッキン６摺動部から歯車箱内へ浸入することが確認された。水が浸入することで潤滑剤が変質してしまい、その機能を十分果たせなくなりギヤの潤滑不良の問題が発生した。浸入した水の大部分はパッキン６を越えて、潤滑剤の戻し穴１５から浸入しており、戻し穴１５を塞ぐことで水浸入防止を行った。しかしながら、水の浸入は激減したが、潤滑剤の漏れが再発した。そのため、潤滑剤の漏れが無い状態を保ちながら、さらに外部からの水浸入を低減する歯車箱の需要が高まった。 In particular, in a locomotive traveling in a snowfall area, a large amount of snow accumulates in the gear box 1, and as shown in FIG. 12, the snow melts and travels along the side wall of the gear box 1 from the packing 6 sliding portion to the inside of the gear box. It was confirmed that it penetrated into. The intrusion of water changed the quality of the lubricant, making it unable to perform its function sufficiently and causing the problem of poor gear lubrication. Most of the infiltrated water passed through the packing 6 and entered the lubricant return hole 15, and the water return was prevented by closing the return hole 15. However, water ingress decreased dramatically, but the lubricant leakage recurred. For this reason, there has been an increasing demand for a gear box that further reduces water intrusion from the outside while maintaining a state in which no lubricant leaks.

そこで、本発明は、歯車潤滑剤の漏れを減少させ、尚且つ歯車箱内への水浸入を低減することが可能な車両駆動装置を提供することを目的とする。 Accordingly, an object of the present invention is to provide a vehicle drive device that can reduce leakage of gear lubricant and reduce water intrusion into the gear box.

上記課題は、機関車を駆動する回転電機と、この回転電機の駆動軸に接続されたピニオンと、機関車の車軸に固定され、前記ピニオンと接したギヤと、前記ピニオンと前記ギヤを覆う歯車箱と、この歯車箱と駆動軸の間に、並列に設けられた複数のパッキンと、このパッキンの間に設けられ、前記歯車箱内へ戻る潤滑剤が流れる潤滑穴と、前記歯車箱のに設けられた水切り板とを備えたことにより達成することが出来る。   The above-described problems include a rotating electrical machine that drives a locomotive, a pinion connected to a drive shaft of the rotating electrical machine, a gear that is fixed to the axle of the locomotive and is in contact with the pinion, and a gear that covers the pinion and the gear A box, a plurality of packings provided in parallel between the gear box and the drive shaft, a lubrication hole provided between the packings and through which the lubricant returning into the gear box flows, and the gear box This can be achieved by providing the draining plate provided.

本発明により、歯車潤滑剤の漏れを減少させ、尚且つ歯車箱内への水浸入を低減することが可能な車両駆動装置を提供すること According to the present invention, there is provided a vehicle drive device capable of reducing gear lubricant leakage and reducing water intrusion into a gear box.

（第１の実施の形態）
本発明に基づく第１の実施の形態の車両駆動装置について図を参照し詳細に説明する。 (First embodiment)
A vehicle drive device according to a first embodiment of the present invention will be described in detail with reference to the drawings.

図１は、本発明に基づく第１の実施の形態の車両駆動装置の構成図である。 FIG. 1 is a configuration diagram of a vehicle drive device according to a first embodiment of the present invention.

本発明に基づく第１の実施の形態の車両駆動装置は、図７に示すように車両床下の台車枠内の狭いスペースに、車輪軸７を覆うサスペンションチューブ８を有す回転電機３が台車に固定されている。回転電機３は回転電機軸９の先端にピニオン２を有し、車輪４はその車輪軸７にギヤボス１０を有すギヤ５を有し、そのギヤ５とピニオン２は回転電機３に固定されている歯車箱１の中で、潤滑剤を介して動力伝達を行う。 In the vehicle drive apparatus according to the first embodiment of the present invention, as shown in FIG. 7, the rotating electrical machine 3 having the suspension tube 8 covering the wheel shaft 7 is installed in a cart in a narrow space in the cart frame under the vehicle floor. It is fixed. The rotating electrical machine 3 has a pinion 2 at the tip of the rotating electrical machine shaft 9, the wheel 4 has a gear 5 having a gear boss 10 on the wheel shaft 7, and the gear 5 and the pinion 2 are fixed to the rotating electrical machine 3. In the gear box 1 that is present, power is transmitted via a lubricant.

このように構成された車両駆動装置において、図８に示す２分割型の歯車箱１は、歯車箱１上下の合わせ面１３と、回転電機鏡ふたとの接合部およびギヤボス１０とのパッキン６摺動部を有す。また図１に示すように、はかま１１の溝にパッキン６を２段並列させ、ギヤボス１０との摺動部をシールする。歯車箱合わせ面１３は、組立後はかま１２で合わせ目が覆われシールされる（図１０参照）。本歯車の潤滑剤には潤滑剤を使用しており、パッキン６でシールできない潤滑剤は歯車箱１から漏れるため、第１２図に示すように、潤滑剤戻し穴１５から歯車箱１の中に戻る構造となっている。パッキン６の性能限界で潤滑剤が漏れる事象が確認されたが、パッキン６を２段並列にしたこととこの潤滑剤戻し穴構造にしたことで、潤滑剤の漏れは激減した。 In the vehicle drive device configured as described above, the two-divided gear box 1 shown in FIG. 8 includes a packing 6 slide between the joint surface 13 on the upper and lower sides of the gear box 1 and the rotating electrical machine mirror lid and the gear boss 10. Has moving parts. Further, as shown in FIG. 1, two stages of packing 6 are juxtaposed in the groove of the kettle 11 to seal the sliding portion with the gear boss 10. After the assembly, the gear box mating surface 13 is covered with a hook 12 and sealed (see FIG. 10). Since a lubricant is used as the lubricant for this gear and the lubricant that cannot be sealed with the packing 6 leaks from the gear box 1, as shown in FIG. 12, the lubricant return hole 15 enters the gear box 1 as shown in FIG. It has a back structure. Although an event that the lubricant leaked at the performance limit of the packing 6 was confirmed, the leakage of the lubricant was drastically reduced by arranging the packing 6 in two stages in parallel and using this lubricant return hole structure.

このように構成された車両駆動装置は、図１に示すように、はかま１１の外周部に薄い円弧状の水きり板１６（液体流入防止手段）で、樋を設けることを特徴のひとつとしている。降雪地区で歯車箱１には雪が大量に積もり、積雪が融解して水となり、はかま１１のほうへ流れてきても、水きり板１６により水の流れが限定され、水は、はかま１を周方向に流れ、歯車箱１の下側に流れ落ちる。そのため、水は、はかま１１を超えて、フェルトシール摺動部に達すること無く、歯車箱１への水浸入を軽減することができる。 As shown in FIG. 1, the vehicle drive device configured as described above is characterized in that a hook is provided on the outer peripheral portion of the kettle 11 with a thin arc-shaped draining plate 16 (liquid inflow prevention means). In the snowfall area, a large amount of snow accumulates in the gear box 1, and the snow melts into water and flows toward the hama 11, but the flow of water is limited by the water drainage plate 16, and the water moves around the hull 1 in the circumferential direction. To the lower side of the gear box 1. Therefore, water can reduce water intrusion into the gear box 1 without exceeding the kettle 11 and reaching the felt seal sliding portion.

このように構成された車両駆動装置は、２段並列に設けられたパッキン６の間に潤滑剤戻し穴１５を備え、はかま１１の外周部に水切り板１６を設けているので、歯車潤滑剤の漏れを減少させ、尚且つ歯車箱内への水浸入を低減することが可能となる。 The vehicle drive device configured as described above includes the lubricant return hole 15 between the packings 6 arranged in parallel in two stages, and the draining plate 16 is provided in the outer peripheral portion of the kettle 11, so that the gear lubricant Leakage can be reduced and water intrusion into the gearbox can be reduced.

（第２の実施の形態）

A vehicle drive apparatus according to a second embodiment of the present invention will be described in detail with reference to the drawings.

図２は、本発明に基づく第２の実施の形態の車両駆動装置の構成図である。図３は、水切り板１６と仕切り板１７の構成図である。尚、図１に記載したものと同一の構造をとるものについては、同符号を付して説明を省略する。 FIG. 2 is a configuration diagram of a vehicle drive device according to a second embodiment of the present invention. FIG. 3 is a configuration diagram of the draining plate 16 and the partition plate 17. In addition, about the thing which has the same structure as what was described in FIG. 1, the same code | symbol is attached | subjected and description is abbreviate | omitted.

本発明に基づく第２の実施の形態の車両駆動装置は、はかま１１に取り付けた水切り板１６（液体流入防止手段）に更に、歯車箱１の合わせ面より上部に、斜め下方向に傾斜のついた仕切り板１７（液体流入防止手段）を設けたことを特徴のひとつとする。 In the vehicle drive device of the second embodiment based on the present invention, a draining plate 16 (liquid inflow prevention means) attached to the kettle 11 is further inclined obliquely downward above the mating surface of the gear box 1. Another feature is that a partition plate 17 (liquid inflow prevention means) is provided.

このように構成された車両駆動装置は、水切り板１６に、仕切り板１７を設けているので、はかま１１の側壁を流れる水を浸入経路から更に遠ざけることができる。そのため、本実施の形態の車両駆動装置は、第１の実施の形態の車両駆動装置よりも、水が浸入する量を軽減することができる。 In the vehicle drive device configured as described above, since the partition plate 17 is provided on the draining plate 16, the water flowing through the side wall of the kettle 11 can be further away from the intrusion path. Therefore, the vehicle drive device according to the present embodiment can reduce the amount of water that enters the vehicle drive device according to the first embodiment.

また、本実施の形態の車両駆動装置も、歯車潤滑剤の漏れを減少させ、尚且つ歯車箱内への水浸入を低減することが可能となる。 In addition, the vehicle drive apparatus according to the present embodiment can also reduce the leakage of the gear lubricant and reduce water intrusion into the gear box.

このように構成された車両駆動装置は、水切り板１８を（液体流入防止手段）設けているので、はかま１１の側壁を流れる水を浸入経路から更に遠ざけることができる。 Since the vehicle drive device configured as described above is provided with the draining plate 18 (liquid inflow prevention means), the water flowing through the side wall of the kettle 11 can be further away from the intrusion path.

また、本実施の形態の車両駆動装置も、歯車潤滑剤の漏れを減少させ、尚且つ歯車箱内への水浸入を低減することが可能となる。 In addition, the vehicle drive apparatus according to the present embodiment can also reduce the leakage of the gear lubricant and reduce water intrusion into the gear box.
