Description

本発明は、着雪防止手段を備えた鉄道車両に関するものである。   The present invention relates to a railway vehicle provided with snow accretion prevention means.

鉄道車両へ着雪が生じると、着雪した雪が塊として地面に落下した際、その衝撃で軌道上のバラストと呼ばれる石を跳ね上げ、床下機器を損傷させるという問題がある。
特に、車両を支持し駆動させる台車が存在する空隙部には、多くの着雪が観測されている。この台車空隙部においては、車両表面に沿って流れてきた、雪を含んだ主流の空気流れ（以下、主流という）が、台車空隙部の進行方向前側塞ぎ板において剥離し、台車内部の機器類の周りを流れ、そして後側塞ぎ板に付着する。
一般に、着雪は流れの圧力が高く流速の遅いよどみ領域に発生しやすい。そのため、鉄道車両の台車空隙部においては、雪を含んだ主流は、台車内部の機器類や下流側の塞ぎ板によってせき止められてよどみ領域が形成されて着雪を発生する。
従って、台車部の着雪を防止する方法としては、着雪箇所周りの形状変更により流れを局所的に制御し、着雪箇所となるよどみ領域を小さくする方法と、雪を含んだ主流を台車内部に入り込むのを抑制する方法とが考えられる。 When a snowfall occurs on a railway vehicle, there is a problem that when the snow falling on the rail falls as a lump to the ground, the impact causes the stone called ballast on the track to jump up and damage the equipment under the floor.
In particular, a lot of snow has been observed in the gap where a carriage for supporting and driving the vehicle is present. In this bogie gap, the mainstream air flow including snow that flows along the surface of the vehicle (hereinafter referred to as main flow) peels off at the front closing plate in the traveling direction of the bogie gap, and the equipment inside the bogie Flows around and adheres to the backplate.
In general, snow accretion tends to occur in a stagnation region where the flow pressure is high and the flow velocity is slow. Therefore, in the bogie gap of the railway vehicle, the mainstream including snow is dammed up by equipment inside the bogie and a closing plate on the downstream side to form a stagnation region and generate snow.
Therefore, there are two methods for preventing the snow from falling on the bogie part: a method of locally controlling the flow by changing the shape around the snow spot, reducing the stagnation area that becomes the snow spot, and the mainstream including snow A method for suppressing the entry into the interior is conceivable.

着雪箇所周りの形状を変更し、よどみ領域を小さくする着雪の防止手法として例えば、特開平９−２６４０１１公報、特開平１０−２０４８３４公報などが挙げられる。
特開平９−２６４０１１公報に記載の構造は、道路標識表面の鉛直上部に整流板を設置して流れを一方向に流すことによって、着雪箇所となる道路標識表面に流れのよどみ領域を発生させない方法である。
また、特開平１０−２０４８３４公報に記載の構造は、防眩装置自体を角柱形状から円柱形状とし、よどみ領域の縮小をはかり、着雪を防止するものである。 Examples of methods for preventing snowfall by changing the shape around the snowfall location and reducing the stagnation area include JP-A-9-264011 and JP-A-10-204834.
The structure described in Japanese Patent Application Laid-Open No. 9-264011 does not generate a stagnation region of the flow on the surface of the road sign that becomes a snow landing point by installing a baffle plate in the vertical upper part of the road sign surface and flowing the flow in one direction. Is the method.
Further, the structure described in Japanese Patent Laid-Open No. 10-204834 is intended to prevent the snow accretion by reducing the stagnation region by changing the antiglare device itself from a prismatic shape to a cylindrical shape.

また、主流が台車内部に入り込むのを抑制する方法として、特許第３１７３２５５号がある。これは台車下部に台車機器を覆うような台車カバーを設置し、台車機器にあたる流れを抑制することで、騒音を低減するのものである。   Japanese Patent No. 3173255 is a method for suppressing the mainstream from entering the carriage. This is intended to reduce noise by installing a cart cover that covers the cart device at the lower portion of the cart and suppressing the flow of the cart device.

上述したように、鉄道車両床下部に着雪が起こると、着雪した雪が塊となって地面に落下し、その衝撃で軌道上の石を跳ね上げ、跳ね上げられた石で床下機器を損傷させるという問題がある。
これを防ぐため、積雪を検出した場合、現状では車両の走行速度を制限している。しかしながら、走行速度を制限することは近年の高速化時代に逆行することになるため、鉄道会社から床下台車部への着雪低減要求が極めて高い。 As mentioned above, when snow occurs in the lower part of the railroad car floor, the snow that has fallen into the snow falls into the ground, and the impact causes the stone on the track to jump up and damage the underfloor equipment with the raised stone. There is a problem.
In order to prevent this, when snow is detected, the traveling speed of the vehicle is currently limited. However, restricting the traveling speed goes against the recent high-speed era, so there is a very high demand for reducing the amount of snow on the undercarriage from the railway company.

本発明の目的は、床下台車部の着雪を低減できる着雪防止手段を備えた鉄道車両を提供することにある。   An object of the present invention is to provide a railway vehicle provided with snow accretion prevention means that can reduce snow accretion at an underfloor truck.

上記目的は、車両本体が進行する方向の前側と後側に設けられた塞ぎ板で形成された空隙と、この空隙内に設置された台車と、この台車に取り付けられ車輪を有する２本の車軸とを備えた鉄道車両において、前記空隙部に前記車両本体の前後進行方向の形状が流線形となった整流部材を設け、この整流部材で前記車両本体の走行による走行風を重心方向に押さえることにより達成される。   The object is to form a gap formed by closing plates provided on the front side and the rear side in the direction in which the vehicle body travels, a carriage installed in the gap, and two axles having wheels attached to the carriage. In the railway vehicle provided with a rectifying member in which the shape of the vehicle body in the front-rear direction is streamlined in the gap, the running air generated by the traveling of the vehicle body is suppressed in the center of gravity direction by the rectifying member. Is achieved.

また、上記目的は、前記整流部材の前縁及び後縁の断面形状が円若しくは楕円であることにより達成される。   Moreover, the said objective is achieved when the cross-sectional shape of the front edge and rear edge of the said baffle member is a circle | round | yen or an ellipse.

また、上記目的は、前記整流部材を前記車両の進行方向に対して左右に分離したことにより達成される。   Moreover, the said objective is achieved by isolate | separating the said baffle member right and left with respect to the advancing direction of the said vehicle.

また、上記目的は、前記整流部材を前記車両の進行方向に対して左右に分離するとともに、前記整流部材の前記車輪近傍の端部が前記車輪より外側に位置することにより達成される。   Further, the above object is achieved by separating the rectifying member left and right with respect to the traveling direction of the vehicle and positioning an end portion of the rectifying member in the vicinity of the wheel outside the wheel.

また、上記目的は、前記整流部材を前記車両の進行方向に対して左右に分離するとともに、前記整流部材の前記車輪近傍の端部が前記車輪より内側に位置することにより達成される。   The object is achieved by separating the rectifying member to the left and right with respect to the traveling direction of the vehicle, and the end of the rectifying member in the vicinity of the wheel being located inside the wheel.

また、上記目的は、前記整流部材が左右方向に可動可能であることことにより達成される。   Moreover, the said objective is achieved by the said rectification | straightening member being movable in the left-right direction.

本発明によれば、床下台車部の着雪を低減できる着雪防止手段を備えた鉄道車両を提供できる。   ADVANTAGE OF THE INVENTION According to this invention, the rail vehicle provided with the snow accretion prevention means which can reduce the snow accretion of an underfloor trolley | bogie part can be provided.

ところで、一般的な鉄道車両台車を図１１で説明する。
図１１において、車両本体１に搭載された台車は進行方向の前側にある塞ぎ板１０と後方の塞ぎ板１１によって形成された空隙内に設置されている。この台車は進行方向２１に対して、２本の車軸３を有し、それぞれの車軸３周りの機器は同様な配置となっている。駆動台車の場合は車輪駆動用モータ４が、ギアボックス５内のギアを介して、車軸３に結合されており、車輪２を回転させる。その他に台車枠６と、車軸３を結合する軸受けが内装されている軸箱７や、台車枠６と車両本体１を結合し駆動力を伝達する一本リンク８からなる。また、台車中心には増圧シリンダカバー９が２つ進行方向に対して左右に配置される。 By the way, a general railway vehicle bogie will be described with reference to FIG.
In FIG. 11, the carriage mounted on the vehicle body 1 is installed in a gap formed by a closing plate 10 on the front side in the traveling direction and a closing plate 11 on the rear side. This carriage has two axles 3 with respect to the traveling direction 21, and the devices around the axles 3 are arranged in the same manner. In the case of a driving carriage, a wheel driving motor 4 is coupled to the axle 3 via a gear in a gear box 5 and rotates the wheel 2. In addition, it includes a bogie frame 6 and a shaft box 7 in which a bearing for coupling the axle 3 is built, and a single link 8 for coupling the bogie frame 6 and the vehicle body 1 to transmit driving force. In addition, two pressure increasing cylinder covers 9 are arranged on the left and right of the traveling direction at the center of the carriage.

この一般的な鉄道車両台車周りにおける空気流れを図４の模式図で説明する。
図４において、一般的な車両の本体１に搭載された台車に対し、雪を含んだ流れ２２は増圧シリンダカバー９によって大きくせき止められ、この部分によどみ領域が形成されて着雪９Ａが発生してしまう。また増圧シリンダカバー９が無い、進行方向と垂直な横方向の台車中心部および、軸箱位置の個所では、雪を含んだ流れ２２が台車内部に入り込み台車構成機器に直接当たるため、その表面にも着雪９Ａが発生する。 The air flow around the general railway vehicle carriage will be described with reference to the schematic diagram of FIG.
In FIG. 4, the flow 22 including snow is greatly dammed by the pressure-increasing cylinder cover 9 with respect to the carriage mounted on the main body 1 of a general vehicle, and a stagnation region is formed in this portion to generate snow accretion 9A. Resulting in. In addition, in the center portion of the carriage in the lateral direction perpendicular to the traveling direction and the position of the axle box where there is no pressure-increasing cylinder cover 9, the snow-containing flow 22 enters the inside of the carriage and directly hits the carriage components. In addition, snowfall 9A occurs.

これら床下台車部への着雪を防止するために、前述した２つの方法（特許文献１、２に記載された方法と特許文献３に記載された方法）、着雪箇所周りの形状を変更してよどみ領域を小さくする方法、台車下部に台車機器を覆うようなカバーを設置する方法とがあるが、これらの方法には次のような問題点がある。   In order to prevent snow on these undercarriage trucks, the two methods described above (the methods described in Patent Documents 1 and 2 and the method described in Patent Document 3) and the shape around the snowing point were changed. There are a method of reducing the stagnation region and a method of installing a cover that covers the bogie equipment at the bottom of the bogie, but these methods have the following problems.

第１の方法である、着雪箇所周りの形状を変更してよどみ領域を小さくする方法にあっては、鉄道車両の台車は車輪、車軸、モータ、ギアボックス、軸箱、増圧シリンダカバー等多くの機器から構成されており、それら全ての機器の着雪を防ぐためには、全ての機器の形状変更が必要であり費用の点で問題がある。   In the first method, which is to reduce the stagnation area by changing the shape around the snow-covered part, the railcar bogie includes wheels, axles, motors, gear boxes, axle boxes, pressure-increasing cylinder covers, etc. It is composed of many devices, and in order to prevent snowing of all these devices, it is necessary to change the shape of all the devices, which is problematic in terms of cost.

また、第２の方法である、台車下部に台車機器を覆うような台車カバーを設置した場合は次のような問題点があるので、その問題点を図９、図１０を用いて説明する。
図９において、車両本体１に搭載された台車は進行方向の前側にある塞ぎ板１０と後方の塞ぎ板１１によって形成された空隙内に設置されている。この台車は進行方向２１に対して、２本の車軸３を有し、それぞれの車軸３周りの機器は同様な配置となっている。駆動台車の場合は車輪駆動用モータ４が、ギアボックス５内のギアを介して、車軸３に結合されており、車輪２を回転させる。
その他に台車枠６と、車軸３を結合する軸受けが内装されている軸箱７や、台車枠６と車両本体１を結合し駆動力を伝達する一本リンク（図示せず）からなる。１２は台車カバーであり、台車中心でかつ車両の進行方向に対して左右に２個配置に取り付けられた増圧シリンダカバー（図示せず）を覆うものである。この台車カバー１２は前記一本リンク及び増圧シリンダカバーを広範囲に覆うものである。 In addition, when a cart cover that covers the cart device is installed in the lower portion of the cart, which is the second method, there are the following problems, which will be described with reference to FIGS. 9 and 10.
In FIG. 9, the carriage mounted on the vehicle body 1 is installed in a gap formed by a closing plate 10 on the front side in the traveling direction and a closing plate 11 on the rear side. This carriage has two axles 3 with respect to the traveling direction 21, and the devices around the axles 3 are arranged in the same manner. In the case of a driving carriage, a wheel driving motor 4 is coupled to the axle 3 via a gear in a gear box 5 and rotates the wheel 2.
In addition, it includes a bogie frame 6 and a shaft box 7 in which a bearing for coupling the axle 3 is housed, and a single link (not shown) that couples the bogie frame 6 and the vehicle body 1 and transmits a driving force. Reference numeral 12 denotes a carriage cover, which covers a pressure-increasing cylinder cover (not shown) attached to the center of the carriage and two left and right with respect to the traveling direction of the vehicle. The carriage cover 12 covers the single link and the pressure increasing cylinder cover over a wide range.

確かに、この台車カバー１２で車輪を除く台車全域を覆ってしまえば床下台車部への着雪を防止することが可能であるが、走行時の流体力変動が台車からカバーに伝播して振動による騒音が発生することや、台車カバー１２が台車の保守作業を邪魔して作業を困難にしてしまことなどから、カバーの取り付けは現実的ではない。   Certainly, it is possible to prevent snow on the under-floor truck by covering the entire carriage except for the wheels with this carriage cover 12, but the fluid force fluctuation during traveling propagates from the carriage to the cover and vibrates. The installation of the cover is not realistic because of the generation of noise due to the fact that the carriage cover 12 interferes with the maintenance work of the carriage and makes the work difficult.

このように台車全域を覆うカバーによることなく、台車への積雪小さくすることを本発明の発明者らが種々検討した結果、以下のような実施例を得た。
以下、本発明の実施例を順次説明する。 As a result of various studies by the inventors of the present invention to reduce the amount of snow on the carriage without using a cover covering the entire area of the carriage, the following examples were obtained.
Hereinafter, embodiments of the present invention will be sequentially described.

図１は、本発明の第１の実施例を模式的に示した平面図である。
図１において、車両本体１に搭載された台車は進行方向の前側にある塞ぎ板１０と後方の塞ぎ板１１によって形成された空隙内に設置されている。この台車は進行方向２１に対して、２本の車軸３を有し、それぞれの車軸３周りの機器は同様な配置となっている。駆動台車の場合は車輪駆動用モータ４が、ギアボックス５内のギアを介して、車軸３に結合されており、車輪２を回転させる。 FIG. 1 is a plan view schematically showing a first embodiment of the present invention.
In FIG. 1, the carriage mounted on the vehicle body 1 is installed in a gap formed by a closing plate 10 on the front side in the traveling direction and a closing plate 11 on the rear side. This carriage has two axles 3 with respect to the traveling direction 21, and the devices around the axles 3 are arranged in the same manner. In the case of a driving carriage, a wheel driving motor 4 is coupled to the axle 3 via a gear in a gear box 5 and rotates the wheel 2.

その他に台車枠６と、車軸３を結合する軸受けが内装されている軸箱７や、台車枠６と車両本体１を結合し駆動力を伝達する一本リンク８からなる。１３は整流部材であり、台車の枕木方向に２個（車両進行方向に対し左右に一つずつ）設置されている。   In addition, it includes a bogie frame 6 and a shaft box 7 in which a bearing for coupling the axle 3 is built, and a single link 8 for coupling the bogie frame 6 and the vehicle body 1 to transmit driving force. Reference numeral 13 denotes a rectifying member, and two rectifying members are installed in the direction of the sleepers of the carriage (one each on the left and right with respect to the vehicle traveling direction).

この整流部材１３は、一本リンク８を避けるようにして左右２箇所に設置されているので、一本リンク８が鉛直下側から視認できる状態になっている。これは、保守時の作業性が向上に繋がる。   Since this rectification member 13 is installed in two places on the left and right sides so as to avoid the single link 8, the single link 8 is in a state where it can be visually recognized from the vertically lower side. This leads to improved workability during maintenance.

図２は第１の実施例における流線形整流部材の縦断面図である。
図２において、整流部材１３は前後縁形状が流線形となっているので、整流部材自体が大きなよどみ領域が形成されなくり、整流部材１３自体の着雪を低減できる。 FIG. 2 is a longitudinal sectional view of the streamline rectifying member in the first embodiment.
In FIG. 2, since the rectifying member 13 has a streamlined front and rear edge shape, a large stagnation region is not formed in the rectifying member itself, and snowfall of the rectifying member 13 itself can be reduced.

図３は第１の実施例における流れを示す模式図である。
尚、図３を説明するために流線形の整流部材が無い状態の流れを図５の模式図と比較して説明する。
図５において、整流部材１３が無い場合は、車両表面に沿って流れてきた雪を含んだ流れ２２が、車両進行方向前側塞ぎ板で一旦剥離し、台車空隙部に多く入り込み、後側車軸周りのモータ、ギアケース、軸箱等の台車機器に直接衝突するため、多くの着雪７Ａや１１Ａとなって発生する。 FIG. 3 is a schematic diagram showing the flow in the first embodiment.
In order to explain FIG. 3, the flow without a streamline rectifying member will be described in comparison with the schematic diagram of FIG. 5.
In FIG. 5, when there is no rectifying member 13, the snow-containing flow 22 flowing along the vehicle surface is once peeled off by the front closing plate in the vehicle traveling direction, enters a large amount in the bogie gap, and around the rear axle. This causes a lot of snowfall 7A and 11A because it directly collides with cart equipment such as motors, gear cases and axle boxes.

これに対し、図３のように流線形の整流部材１３がある場合は、雪を含んだ主流は、車両進行方向前側塞ぎ板で一旦剥離し、整流部材表面に着雪した後にもう一度剥離し、下流側塞ぎ板に着雪する。
このように流れを流線形の整流部材に付着させることで、台車空隙部への流れ込みを抑制し、台車機器の着雪を低減できる。この整流部材の鉛直下面を車両床下面と略同一高さとすると、台車空隙部への流れの入り込みを大きく抑制でき、着雪を大きく低減できる。 On the other hand, when there is a streamlined rectifying member 13 as shown in FIG. 3, the mainstream including snow is once peeled off at the front blocking plate in the vehicle traveling direction, and once peeled off on the rectifying member surface, It snows on the downstream closing plate.
By attaching the flow to the streamline rectifying member in this way, it is possible to suppress the flow into the bogie gap and reduce the snow accretion of the bogie equipment. When the vertical lower surface of the rectifying member is substantially the same height as the lower surface of the vehicle floor, it is possible to greatly suppress the entry of the flow into the bogie gap and to greatly reduce snow accretion.

また、この流線形整流部材の車両進行方向と垂直な横方向の寸法を、軸箱より外側まで大きくすることによって、モータ、ギアボックス、軸箱等のほぼ全ての台車機器に、雪を含んだ主流が直接衝突することを抑制できるので、その結果、ほぼ全ての台車機器の着雪を防止することができる。   Also, by increasing the lateral dimension of this streamline rectifying member perpendicular to the vehicle traveling direction to the outside of the axle box, almost all bogie equipment such as motors, gear boxes, axle boxes, etc. contained snow. Since the mainstream can be prevented from directly colliding, as a result, it is possible to prevent snowing of almost all cart equipment.

図６は第２の実施例を示す図１相当図である。
図６が図１に示す第１の実施形態と異なる点は、台車空隙部に設置する整流部材１３の車両進行方向と垂直な横方向寸法を、車輪付近まで短縮した点である。
これにより、２つの車輪に挟まれた流れは前記図１に示す実施の形態と大きく変化することがないので、第１の実施形態と同様に着雪防止効果が得られる。 FIG. 6 is a view corresponding to FIG. 1 showing a second embodiment.
FIG. 6 differs from the first embodiment shown in FIG. 1 in that the lateral dimension perpendicular to the vehicle traveling direction of the rectifying member 13 installed in the bogie gap is shortened to the vicinity of the wheel.
As a result, the flow sandwiched between the two wheels does not change greatly from the embodiment shown in FIG. 1, so that the effect of preventing snow accretion can be obtained as in the first embodiment.

一方、軸箱の位置に流線形の整流部材１３が無いため、鉛直下方から雪を含んだ流れが巻き上がり、軸箱に衝突する流れは多くなり、着雪は若干悪化する。しかし、軸箱にあたる流れは車両進行方向と垂直な横側からの流れ込みも多く、この横側からの着雪に対する寄与も大きいため、整流部材短縮による着雪増加の影響はそれほど大きくない。また、本実施例によれば、第１の実施例より、保守時の作業性が向上する。   On the other hand, since there is no streamline rectifying member 13 at the position of the axle box, the flow including snow rises from vertically below, the flow that collides with the axle box increases, and snow accretion is slightly worsened. However, since the flow corresponding to the axle box also flows in from the lateral side perpendicular to the vehicle traveling direction and greatly contributes to snow accretion from the lateral side, the influence of the increase in snow accretion due to the shortening of the rectifying member is not so great. Further, according to the present embodiment, workability during maintenance is improved as compared with the first embodiment.

図７は第３の実施例を備えた図１相当図である。
図７が第１の実施例と第２の実施例と異なる点は、台車空隙部に設置する流線形の整流部材の、車両進行方向と垂直な横方向寸法を、車輪内側まで短縮した点である。
２つの車輪の内側に挟まれた流れは前記図１および図２に示す実施の形態と大きく変化することがないので、第１および第２の実施形態と同様に着雪防止効果が得られる。一方、車輪部では、車輪の位置に整流部材が無いため、車輪にあたる雪を含んだ流れが多くなるものの、車輪自体は回転しているため着雪の悪化はわずかである。そのため整流部材短縮による着雪の影響はそれほど大きくない。
尚、本実施例によれば、第２の実施例よりも更に保守時の作業性が向上する。 FIG. 7 is a view corresponding to FIG. 1 provided with the third embodiment.
FIG. 7 is different from the first embodiment and the second embodiment in that the lateral dimension of the streamline rectifying member installed in the carriage gap is shortened to the inside of the wheel. is there.
Since the flow sandwiched between the two wheels does not change significantly from the embodiment shown in FIG. 1 and FIG. 2, the effect of preventing snow accretion can be obtained as in the first and second embodiments. On the other hand, in the wheel portion, since there is no rectifying member at the position of the wheel, although the flow including snow that hits the wheel increases, the deterioration of snow accretion is slight because the wheel itself rotates. Therefore, the effect of snowfall due to the shortening of the rectifying member is not so great.
According to this embodiment, the workability during maintenance is further improved as compared with the second embodiment.

図８は第４の実施例を示す図２相当図である。
本実施例が第１、第２、および第３の実施例と異なる点は、台車空隙部に設置する整流部材の前後縁形状を、円形もしくは楕円形とした点である。
このようにした場合においても、整流部材自体が大きなよどみ領域を形成しないことから、整流部材自体の着雪を低減することができ、また台車全体の流れは図１、図７、および図８に示す実施例と大きく変化することがないので第１、第２、および第３の実施例と同様に着雪防止効果が得られる。 FIG. 8 is a view corresponding to FIG. 2 showing a fourth embodiment.
This embodiment is different from the first, second, and third embodiments in that the shape of the front and rear edges of the rectifying member installed in the bogie gap is a circle or an ellipse.
Even in such a case, since the flow straightening member itself does not form a large stagnation region, it is possible to reduce the snow accretion of the flow straightening member itself, and the flow of the entire carriage is shown in FIG. 1, FIG. 7, and FIG. Since there is no significant change from the embodiment shown, the effect of preventing snow accretion is obtained as in the first, second and third embodiments.

本実施例の整流部材１３は、例えば図４に示されている増圧シリンダカバー９を図２若しくは図５に示したような整流部材１３の形状に変更しても同じ効果を得ることができる。
即ち、台車全体の流れは図１、図６、図７および図８に示す実施の形態と大きく変化することがないので、第１、第２、第３および第４の実施形態と同様に着雪低減効果が得られる。 The flow straightening member 13 of the present embodiment can obtain the same effect even if the pressure increasing cylinder cover 9 shown in FIG. 4 is changed to the shape of the flow straightening member 13 as shown in FIG. 2 or FIG. .
That is, since the flow of the entire carriage is not greatly changed from the embodiment shown in FIGS. 1, 6, 7 and 8, it is worn similarly to the first, second, third and fourth embodiments. Snow reduction effect is obtained.

以上の如く、本発明によれば、鉄道車両の台車空隙部内部に設けられた流線形の整流部材により、雪を含んだ主流が台車内部に入りこむことを抑制することができるので、モータ、ギアボックス、軸箱等の台車を構成する多くの機器に、雪を含んだ主流が直接衝突することを避けることができ、着雪を防止することができる。また、台車内部に設置する流線形の整流部材を複数とすることで、一つの整流部材にかかる流体力変動を小さくすることができ、強度信頼性の点でも問題を解決できる。また、整流部材を主要着雪箇所である台車機器の周囲にのみ設置することで、保守性の点でも問題を解決できる。また、整流部材を、車両進行方向と垂直な横方向に可動式とすることで、走行時の安全性を確保するとともに、保守時の作業性が向上する。   As described above, according to the present invention, the streamline rectifying member provided inside the bogie gap of the railway vehicle can suppress the mainstream including snow from entering the bogie, so that the motor, gear It is possible to prevent the mainstream including snow from directly colliding with many devices constituting a cart such as a box and a shaft box, and snow can be prevented. In addition, by using a plurality of streamline rectifying members installed inside the carriage, it is possible to reduce the fluid force fluctuation applied to one rectifying member and solve the problem in terms of strength reliability. Moreover, the problem can be solved in terms of maintainability by installing the rectifying member only around the bogie equipment which is the main snow landing location. Further, by making the flow straightening member movable in the lateral direction perpendicular to the vehicle traveling direction, safety during traveling is ensured and workability during maintenance is improved.
