Description

この発明は、鉄道車両用全周外幌及びその製造方法に係わり、更に詳しくは、前後車両間の空間部の車両底部を除く全周を覆い、風切り音、車輪とレ−ルの摩擦音、車輪の転動音等が拡散するのを防止して車内騒音を低減すると共に、幌を構成する材料の物性を特定して耐久性を向上させる鉄道車両用全周外幌及びその製造方法に関するものである。   The present invention relates to an all-around outer hood for a railway vehicle and a method for manufacturing the same, and more specifically covers the entire circumference except for the bottom of the vehicle in the space between the front and rear vehicles, wind noise, friction noise between wheels and rails, wheels. This relates to an all-around outer hood for a rail vehicle and a method of manufacturing the same that reduce the noise in the vehicle by preventing the rolling noise of the vehicle from spreading and identify the physical properties of the material constituting the hood to improve the durability. is there.
従来、高速鉄道車両間の空間部を覆う車両用幌は、車両間の内側全周を覆う内幌と、その外側の車両の左右側面のみを覆う外幌から構成されている。前記車両連結部に設けられた内幌は、蛇腹構造に形成され、車内を風雪、ほこり等から保護する役割を果たし、外幌は前後車両の各々の側面に取り付けられた断面U字状のゴム板からなり、車両連結部の美観を呈すると共に、乗客が駅のプラットホームから車両間の空間部の線路に転落するのを防止する役割を果たしてきた(例えば、特許文献1,特許文献2参照)。   2. Description of the Related Art Conventionally, a vehicle hood that covers a space between high-speed railway vehicles is composed of an inner hood that covers the entire inner periphery between vehicles and an outer hood that covers only the left and right side surfaces of the vehicle outside the vehicle. An inner hood provided in the vehicle connecting portion is formed in a bellows structure and serves to protect the inside of the vehicle from wind and snow, dust, etc., and the outer hood is a rubber having a U-shaped cross section attached to the side surfaces of the front and rear vehicles. It consists of a board, and has played the role which prevents that a passenger falls on the track | line of the space part between vehicles from the platform of a station while exhibiting the beauty of a vehicle connection part (for example, refer patent document 1, patent document 2).
上記のような車両用幌は、風雪、ほこり等の侵入を防止するために密封性は考慮されているが、騒音に対しては十分な対策が施されておらず、特に外幌は車両の連結部の全周に配設されていないため、風切り音、車輪とレ−ルの摩擦音、レ−ル継ぎ目でのたたき音、車輪の転動音、パンタグラフ擦り音、等が車両連結部の隙間を通って拡散し、これが床、ガラス窓、内幌等の車体構成物を通って車内に進入し車内騒音の原因となっていた。   The above-mentioned vehicle hoods are considered to be sealed to prevent intrusion of wind and snow, dust, etc., but no sufficient measures are taken against noise. Since it is not arranged all around the connecting part, wind noise, wheel-to-rail friction sound, tapping noise at the rail joint, wheel rolling sound, pantograph rubbing sound, etc. This diffused through the vehicle body components such as floors, glass windows, and inner hoods, and entered the car, causing noise in the car.
上記する風切り音、車輪とレ−ルの摩擦音等の騒音が拡散するのを一次的に防止させるには、車両連結部を幌で覆い車両同志を柔軟性に富む材料でシ−ルするのが好ましく、このことから発明者等は先ず車両連結部における車両底部を除く全周を外幌で覆うことを考えた。   In order to prevent the wind noise and the frictional noise of the wheels and rails from diffusing primarily, the vehicle connecting part is covered with a hood and the vehicles are sealed with a flexible material. Preferably, from this, the inventors first considered covering the entire circumference of the vehicle connecting portion except for the vehicle bottom with an outer hood.
然しながら、外幌を上記のように配置すると車両の両肩部では外幌の形状を車両の両肩部に沿った形状にする必要があるため、特に操車場等のような曲率半径の小さい軌道を走行する場合には、外幌の両肩部が柔軟に対応できず、外幌の両肩部が早期に摩耗、損傷し製品寿命を短くするという問題に直面した。

However, if the outer hood is arranged as described above, it is necessary to make the shape of the outer hood along the shoulders of the vehicle at the shoulders of the vehicle. When traveling on the road, both shoulders of the outer hood could not be flexibly adapted, and both shoulders of the outer hood were quickly worn and damaged, leading to a problem of shortening the product life.

この発明はかかる従来の問題点に着目し、車内騒音を低減させると共に、耐久性に優れた鉄道車両用全周外幌及びその製造方法を提供することを目的とするものである。   An object of the present invention is to provide an all-around outer hood for a railway vehicle and a method of manufacturing the same that reduce the noise in the vehicle and is excellent in durability while paying attention to such conventional problems.
この発明は上記目的を達成するため、この発明の鉄道車両用全周外幌は、前後車両の連結部における車両間の空間部を覆う外幌であって、前記外幌が、前方車両の後端部と後方車両の前端部における車両底部を除く全周にわたり、それぞれ対向して取り付けられた断面略U字状の可撓性板状体から成り、前記外幌の両肩部を構成する材料の弾性率が、天井部及び両側部を構成する材料の弾性率より小さく設定したことを要旨とするものである。   In order to achieve the above object, an all-around outer hood for a railway vehicle according to the present invention is an outer hood that covers a space between vehicles at a connecting portion of front and rear vehicles, and the outer hood is disposed behind a front vehicle. A material that constitutes both shoulders of the outer hood, comprising a flexible plate-like body having a substantially U-shaped cross section that is attached oppositely over the entire circumference except for the vehicle bottom at the end and the front end of the rear vehicle. The gist is that the elastic modulus is set to be smaller than the elastic modulus of the material constituting the ceiling and both sides.
ここで、前記両肩部を構成する材料の弾性率が、天井部及び両側部を構成する材料の弾性率の80〜25%である。   Here, the elastic modulus of the material constituting the shoulder portions is 80 to 25% of the elastic modulus of the material constituting the ceiling portion and the both side portions.
また、この発明の他の鉄道車両用全周外幌は、前後車両の連結部における車両間の空間部の車両底部を除く全周を覆う断面略U字状のゴム製の板状体からなる外幌を製造するに際して、天井部及び両側部のゴム材料と、該ゴム材料より低い弾性率を有する両肩部のゴム材料を成形金型内に配置して一体的に加硫成形することを要旨とするものである。   In addition, another all-round outer hood for a railway vehicle according to the present invention comprises a rubber plate-like body having a substantially U-shaped cross section that covers the entire circumference excluding the vehicle bottom portion of the space portion between the vehicles at the connecting portion of the front and rear vehicles. When manufacturing the outer hood, the rubber material for the ceiling and both sides and the rubber material for both shoulders having a lower elastic modulus than the rubber material are placed in a molding die and integrally vulcanized. It is a summary.
これにより、風切り音、車輪とレ−ルの摩擦音、レ−ル継ぎ目でのたたき音、車輪の転動音、パンタグラフ擦り音、等が拡散するのを防止して車内騒音を低減させる。ここで、外幌を構成する前記可撓性板状体をゴム製の板状体とし、外幌の両肩部を構成する材料の弾性率を、天井部及び両側部を構成する材料の弾性率の80〜25%とすることが好ましい。   This prevents wind noise, wheel-to-rail friction sound, tapping noise at the rail joint, wheel rolling sound, pantograph rubbing sound, and the like from being diffused to reduce vehicle interior noise. Here, the flexible plate-like body constituting the outer hood is a rubber plate-like body, and the elastic modulus of the material constituting the shoulder portions of the outer hood is determined by the elasticity of the material constituting the ceiling portion and both side portions. 80 to 25% of the rate is preferable.
この結果、外幌の肩部における外側面と内側面との曲率差に起因する剛性の違いを小さくして変形しやすくし早期摩耗を防ぎ外幌の耐久性を向上させる。   As a result, the difference in rigidity due to the difference in curvature between the outer side surface and the inner side surface of the shoulder portion of the outer hood is reduced to facilitate deformation, thereby preventing early wear and improving the durability of the outer hood.
また、この発明の鉄道車両用全周外幌の製造方法は、前後車両の連結部における車両間の空間部の車両底部を除く全周を覆う断面略U字状のゴム製の板状体からなる外幌を製造するに際して、天井部及び両側部のゴム材料と、該ゴム材料より低い弾性率を有する両肩部のゴム材料を用意し、天井部と両肩部、または肩部と側部のゴム材料を成形金型内に配置して一体的に加硫成形し、残りの両側部、または天井部のゴム材料を成形金型内で加硫し、これらを合体して一体的に成形することを要旨とするものである。   In addition, the manufacturing method of the all-round outer hood for a railway vehicle according to the present invention is a rubber plate-like body having a substantially U-shaped cross section covering the entire circumference except for the vehicle bottom portion of the space between the vehicles at the connecting portion of the front and rear vehicles. When manufacturing the outer hood, a rubber material for the ceiling and both sides, and a rubber material for both shoulders having a lower elastic modulus than the rubber material are prepared, and the ceiling and both shoulders, or the shoulder and sides are prepared. These rubber materials are placed in a molding die and integrally vulcanized and molded, and the rubber materials on the remaining side or ceiling are vulcanized in the molding die, and these are merged and molded integrally. The gist is to do.
これにより、外幌の継ぎ目を少なくして防音性を改善し、さらには外幌の生産性を向上させる。   As a result, the seams of the outer hood are reduced to improve soundproofing, and further the productivity of the outer hood is improved.
この発明の鉄道車両用全周外幌は、上記のように、車両間の空間部の車両底部を除く全周を環状に覆って配置したため、車外で発生した騒音が拡散するのを防止して車内の騒音を低減させる。また、外幌の両肩部における材料の弾性率を天井部及び両側部の材料の弾性率に比して小としたことにより、両肩部における耐摩耗性を向上させて外幌としての耐久性を向上させる。   As described above, the entire outer hood for a railway vehicle according to the present invention is arranged so as to cover the entire circumference of the space between the vehicles except for the bottom of the vehicle in an annular shape, thereby preventing the noise generated outside the vehicle from diffusing. Reduce noise in the car. In addition, by reducing the elastic modulus of the material at both shoulders of the outer hood compared to the elastic modulus of the material at the ceiling and both sides, the wear resistance at both shoulders is improved and durability as an outer hood Improve sexiness.
この発明による鉄道車両用全周外幌の製造方法は、弾性率の異なるゴム材料からなる外幌の各部位の全部又は一部を一体的に成形加硫することにより、出来上がった外幌の継ぎ目を少なくして防音性を高め、さらには一体的に成形加硫することにより外幌の生産性を向上させる。   According to the present invention, there is provided a method for producing an all-around outer hood for a railway vehicle by integrally molding and vulcanizing all or a part of each part of the outer hood made of rubber materials having different elastic moduli. To improve the soundproofing, and further improve the productivity of the outer hood by integrally molding and vulcanizing.
以下、添付図面に基づき、この発明の実施形態を説明する。
なお、各図において、同一の構成要素には同一の符号を付し、重複した説明を省略する。
Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.
In each figure, the same constituent elements are denoted by the same reference numerals, and redundant description is omitted.
図1は、この発明の外幌が片側の車両の端部に取り付けられた状態を示す一部斜面図で、外幌1は車両2の底部を除く全周にわたり取付けられる。   FIG. 1 is a partial perspective view showing a state in which the outer hood of the present invention is attached to the end of a vehicle on one side. The outer hood 1 is attached over the entire circumference except the bottom of the vehicle 2.
ここで、図1に示すように、車両2の天井部に沿って取り付ける外幌の部位を外幌の天井部a、車両2の両肩部に沿って取り付ける外幌の部位を外幌の両肩部s、車両2の両側部に沿って取り付ける外幌の部位を外幌の両側部bと定義し、以下この定義に使用して説明する。図2は前後車両の連結部を側面から見た説明図で、この発明の外幌1が前方車両の後端部と後方車両の前端部にそれぞれ対向して取付けられている状態を示している。   Here, as shown in FIG. 1, the part of the outer hood attached along the ceiling part of the vehicle 2 is the ceiling part a of the outer hood, and the part of the outer hood attached along both shoulders of the vehicle 2 is the both parts of the outer hood. A portion of the outer hood attached along the shoulder s and both sides of the vehicle 2 is defined as both sides b of the outer hood, and will be described below using this definition. FIG. 2 is an explanatory view of the connecting portion of the front and rear vehicles as viewed from the side, and shows a state in which the outer hood 1 of the present invention is mounted facing the rear end portion of the front vehicle and the front end portion of the rear vehicle. .
図3は、図2のA−A矢視断面図で、外幌2は断面略U字状の可撓性板状体からなり、可撓性板状体の材料としては、一般に、エチレン−プロピレン−ジエンゴム(EPDM)、クロロプレンゴム(CR)、イソプレンゴム(IR)、アクリロニトリル−ブタジエンゴム(NBR)、ブタジエンゴム(BR)、スチレン−ブタジエンゴム(SBR)、天然ゴム(NR)等の群から選択される1種以上のゴムが使用される。   FIG. 3 is a cross-sectional view taken along the line AA in FIG. 2. The outer hood 2 is formed of a flexible plate-like body having a substantially U-shaped cross section, and the material of the flexible plate-like body is generally ethylene- Propylene-diene rubber (EPDM), chloroprene rubber (CR), isoprene rubber (IR), acrylonitrile-butadiene rubber (NBR), butadiene rubber (BR), styrene-butadiene rubber (SBR), natural rubber (NR), etc. One or more selected rubbers are used.
車両1は、操車場、駐車場から営業路線内の軌道上全てを走行するので、特に操車場から車両1を引き出す時等には曲率半径の小さい軌道上を走行するために、互いに対向して取り付けられた外幌1同士が圧縮/伸長の繰り返しによる応力を受け、外幌1の摩耗、破損が避けられない。   Since the vehicle 1 travels all on the track in the business route from the yard and parking lot, particularly when pulling out the vehicle 1 from the yard, the vehicle 1 faces each other in order to travel on the track with a small radius of curvature. The attached outer hoods 1 are subjected to stress due to repeated compression / extension, and the outer hoods 1 cannot be worn or damaged.
特に、図1に示す両肩部sでは、車両中心から見た外幌1の外側面と内側面の曲率差が大きく、天井部aや両側部bに比べて自由変形が拘束されるために、外幌1の摩耗、損傷が早期に発生する。   In particular, the shoulders s shown in FIG. 1 have a large difference in curvature between the outer surface and the inner surface of the outer hood 1 as viewed from the center of the vehicle, and the free deformation is restrained compared to the ceiling portion a and both side portions b. The outer hood 1 is worn and damaged early.
この発明は上記する欠陥を回避するために、両肩部sの材料の硬さを天井部a及び両側部bの材料より柔らかくして変形しやすくし、両肩部sの早期損傷により外幌1の製品寿命が短縮するのを回避するものである。   In order to avoid the above-mentioned defects, the present invention makes the material of both shoulders s softer than the material of the ceiling part a and both side parts b to make it easy to deform. 1 to avoid shortening the product life.
具体的には、両肩部sを構成する材料の弾性率を天井部a及び両側部bを構成する材料の弾性率の80〜25%とし、さらに好ましくは70〜30%とする。   Specifically, the elastic modulus of the material constituting both shoulders s is set to 80 to 25%, more preferably 70 to 30%, of the elastic modulus of the material constituting the ceiling part a and both side parts b.
前記弾性率の差が80%超となると摩耗、損傷に対する有意差が認められず、25%未満では変形が大きくなり過ぎて外幌としての機能が損なわれる。   If the difference in elastic modulus exceeds 80%, no significant difference in wear and damage is observed, and if it is less than 25%, the deformation becomes too large and the function as an outer hood is impaired.
外幌1の材料の弾性率としては種々の場合が想定されるが、各部位の材料を相対的に上記のようにすることにより製品寿命を延ばすことができ、外幌1の耐久性が向上する。   Although various cases are assumed as the elastic modulus of the material of the outer hood 1, the life of the outer hood 1 can be extended by relatively increasing the material of each part as described above, and improving the durability of the outer hood 1. To do.
この発明の外幌1は、全体の重量が車体2への取り付け作業に支障をきたさない限りにおいて、できるだけ長尺の寸法で製造され装着されることが防音性や生産性にとって有利である。   The outer hood 1 of the present invention is advantageous in terms of soundproofing and productivity as long as the overall weight does not hinder the mounting work to the vehicle body 2 and is manufactured and mounted with a length as long as possible.
従って、この発明の外幌1を製造するには、(1)天井部a及び両側部bのゴム材料と、これより低い弾性率を有する両肩部sのゴム材料を成形金型内に配置して一体に加硫する、又は(2)予め各部位のゴム材料を用意しておき、天井部aと両肩部s又は肩部sと側部bのゴム材料を成形金型内に配置して一体に加硫し、残りの両側部b又は天井部aのゴム材料を成形金型内で加硫し、これらを合体する、ことにより行う。   Therefore, in order to manufacture the outer hood 1 of the present invention, (1) the rubber material of the ceiling part a and both side parts b and the rubber material of both shoulder parts s having lower elastic modulus are arranged in the molding die. (2) Prepare the rubber material of each part in advance and place the rubber material of the ceiling part a and both shoulder parts s or the shoulder part s and side part b in the molding die. Then, the vulcanization is performed integrally, and the rubber material of the remaining side portions b or the ceiling portion a is vulcanized in a molding die, and these are united.
これにより、出来上がった外幌1は継ぎ目が少なくなり防音性を高めると共に、各部を一体的に成形加硫することにより外幌の生産性が向上する。   As a result, the finished outer hood 1 has fewer seams and improves soundproofing, and the productivity of the outer hood is improved by integrally molding and vulcanizing each part.
外幌1の肩部sを構成するゴム材料の弾性率が摩耗及び損傷にどの程度の影響を及ぼすかを調べるために、弾性率の異なるゴム材料を使用して外幌1の肩部sの試験品を実物大の略1/2の大きさで製造し、各試験品について以下の試験方法に従い摩耗状況と損傷状況を調べた。   In order to examine how much the elastic modulus of the rubber material constituting the shoulder s of the outer hood 1 affects the wear and damage, rubber materials having different elastic moduli are used for the shoulder s of the outer hood 1. A test product was manufactured to be approximately half the size of the actual size, and each test product was examined for wear and damage according to the following test method.
試験に先立ち弾性率の異なるゴム材料を得るため、加硫促進剤と硫黄を除く配合材料を20リットル容量のニ−ダ−ミキサ−により約15分混合した後、これを18インチの練りロ−ルに巻き付けて加硫促進剤と硫黄を添加し、約10分間混練りした。   Prior to the test, in order to obtain rubber materials having different elastic moduli, the vulcanization accelerator and the compounded material excluding sulfur were mixed for about 15 minutes with a 20 liter kneader mixer and then mixed with an 18 inch kneading roller. A vulcanization accelerator and sulfur were added to the steel sheet and kneaded for about 10 minutes.
これを必要な厚さに圧延して裁断した後、成形金型を使用して150°Cにて2時間の缶加硫を行い以下に述べる各試験品を得た。   This was rolled to a required thickness and cut, and then a can was vulcanized at 150 ° C. for 2 hours using a molding die to obtain each test product described below.
試験品としては、現在使用されている外幌1の天井部a及び両側部bのゴムと同じゴムを使用した試験品Aと、このゴムと異なる弾性率を有する4種のゴムを使用した試験品B,C,D,Eを各々4個ずつ製造した。   As a test product, test product A using the same rubber as the rubber of the ceiling part a and both side parts b of the outer hood 1 currently used, and a test using four kinds of rubber having different elastic modulus from this rubber Four products B, C, D and E were produced.
各試験品についての試験結果を、ゴム材料の配合内訳(重量部)とその物性と共に〔表1〕に示した。   The test results for each test product are shown in [Table 1] together with the breakdown (parts by weight) and physical properties of the rubber material.
なお、〔表1〕の試験結果において摩耗量(%)が2段に併記されているのは対向する各試験品の摩耗量を示し、摩耗量(%)は横擦り試験により減少した重量を試験前の重量で除して、これを100倍にして表示した。
〔試験方法〕
荷重変位特性試験機に取り付け金具を用いて試験品を取り付け、以下の要領により圧縮試験と横擦り試験を行った。
(1)圧縮試験
図4に示すように試験品を上下位置に対応させて、頂上部が互いに接触するように図示しない試験機の面に取り付け、試験機面間が250mmから150mmとなるように往復運動させて試験品同志を押しつけ、これを4500回往復させた後、試験品の破損状況(穴あき個数、ゴム−補強層間の剥がれ状況)を観察した。
In the test results of [Table 1], the amount of wear (%) written in two stages indicates the amount of wear of each facing test piece, and the amount of wear (%) represents the weight reduced by the side-rub test. Dividing by the weight before the test, this was displayed as 100 times.
〔Test method〕
A test article was attached to the load displacement characteristic testing machine using a mounting bracket, and a compression test and a side rubbing test were conducted as follows.
(1) Compression test As shown in FIG. 4, the test product is mounted on the surface of a tester (not shown) so that the tops are in contact with each other, so that the distance between the tester surfaces is 250 mm to 150 mm. The specimens were reciprocated to press the specimens, and after reciprocating 4500 times, the specimens were observed for breakage (number of holes, peeling between rubber and reinforcing layers).
なお、試験品の高さは片側125mmであった。
(2)横擦り試験
図5に示すように試験品を試験機面間が150mmとなるように左右に向かい合わせて試験機に取り付け、この位置から一方の試験機を上下に120mmずつ変位させ、試験品の壁同志を繰り返し擦らせた。これを4500回往復させた後、試験品の摩耗状況を観察した。
The height of the test product was 125 mm on one side.
(2) Lateral rubbing test As shown in FIG. 5, the test product was mounted on the tester facing left and right so that the distance between the tester surfaces was 150 mm, and one tester was displaced vertically by 120 mm from this position. The walls of the test article were repeatedly rubbed. After this was reciprocated 4500 times, the wear state of the test product was observed.
〔表1〕より、試験品Aを基準として比較すると、試験品Bのようにゴムの弾性率(100%モシ゛ュラス(MP) )が高くなると摩耗状況がさらに悪化し、弾性率の低下と共に摩耗状況と損傷状況が改善することを確認した。ただし、前記するように肩部sのゴムの弾性率を天井部a及び両側部bのゴムの弾性率に比して相対的にあまり低下させ過ぎると本来の外幌の形状を維持することができなくなる。   From [Table 1], comparing the test sample A as a standard, as the test sample B, the higher the elastic modulus of the rubber (100% modulus (MP)), the further worse the wear situation, the lower the elastic modulus and the wear situation And confirmed that the damage situation improved. However, as described above, if the elastic modulus of the rubber of the shoulder portion s is relatively lowered as compared with the elastic modulus of the rubber of the ceiling portion a and both side portions b, the original shape of the outer hood can be maintained. become unable.
この実施例2は、実施例1と同様な試験方法により、配合材を変えて試験品Fを試験したもので、その結果を表2に示し、表1の試験品Aを基準として比較すると、弾性率の低下と共に摩耗状況と損傷状況が改善することを確認した。
In this Example 2, the test material F was tested by changing the compounding material by the same test method as in Example 1, the results are shown in Table 2, and compared with the test product A in Table 1 as a reference. It was confirmed that the wear and damage conditions improved with decreasing elastic modulus.
