Description

【0001】
【発明の属する技術分野】
本発明は、鉄道車両用台車において、電動機の固定子を車軸に固定した台車に関するものである。
【0002】
【従来の技術】
鉄道車両用台車において、電動機の固定子を車軸に固定した台車は特開平07−9993号公報に示されている。この種の台車では固定子の冷却が課題となるので、固定子の軸方向の端部から冷却空気を送風するようにしている。
【0003】
【発明が解決しようとする課題】
上記従来技術では空気で冷却しており、効率が悪い。また、電動機の固定子への通電手段については示されていないが、冷却の送風と同様に、固定子の軸方向端部に電線を接続するものと考えられる。
【0004】
本発明は、車軸を中空軸とし、車軸の軸方向端部から車軸内部に冷却用の液体パイプ、電線を配置しようとするものである。この場合、固定子の軸方向端部において、車軸から半径方向にパイプ、電線を曲げることが必要となる。
【0005】
本発明の目的は、冷却パイプを容易に固定できるようにすることにある。
【0006】
【課題を解決するための手段】
上記目的は、
中空の固定車軸の外周に設けた固定子と、その外周に設けた回転子と、該回転子と軸方向の両端側に設けた車輪とを接続する継ぎ手と、
前記固定車軸内に配置され、冷却媒体のパイプの端部に固定した第2の継ぎ手と、
該第2の継ぎ手から半径方向に突出して前記固定子に接続する第3の継ぎ手とからなり、該第3の継ぎ手と前記第2の継ぎ手とをねじで接続すること、
によって達成できる。
【0007】
【発明の実施の形態】
以下、図1から図5によって本発明の一実施例の台車の駆動部分について説明する。
【0008】
両端に貫通する中空の固定車軸10の両端に軸受20を介して車輪21,21を設置している。固定車軸10は両端に貫通した中空軸である。固定車軸10の長手方向の中央部の外側には固定子30を固定している。固定子30の外周に回転子40がある。回転子40は筒状の回転体42の内側に取り付けている。回転体42の両端は中空状の継ぎ手46を介して車輪21の側面に固定している。継ぎ手46はボルト(図示せず)によって車輪21、回転体42に対して着脱自在である。固定子30と回転子40とによって電動機を構成している。
【0009】
中空の固定軸10の一端から電線51が挿入され、固定子30の近くで半径方向に曲げられ、固定子30の軸方向の端部に接続している。固定軸10には電線51を半径方向に通過させる貫通穴11を設けている。貫通穴11は固定軸10を半径方向に貫通している。
【0010】
図2、図3において、貫通穴11には電線51を固定する長方形または棒状の座52を貫通させている。座52の両端は固定車軸の外側の座(図示せず)、または固定子30の軸方向端部の座54にボルト(図示せず)で固定している。電線51は座52にひも(針金に樹脂を被覆したものや樹脂性のバンド等からなる。)53で結合される。座52は電線支えである。
【0011】
これによれば、電線51は固定車軸10の軸端と固定子30との間で固定されているので、固定車軸の軸端側から電線51を引っ張っても、固定子30からはずれる等の問題が発生しないものである。
【0012】
組立方法は、電線51を貫通穴11から固定車軸10の外側に取り出した後、座52の長手方向の中央部に電線51をひも53で固定する。次に、座52を固定車軸10内に入れ、座52の両端を座54に固定する。これによれば、電線51は固定車軸10内において固定されることになる。このため、固定車軸10の外側で固定した場合に比べて、電線51を固定車軸10の軸端側から引っ張った場合に、電線51が貫通穴11の角部に接触することがないなどの利点を発生する。
【0013】
図4、図5によって、冷却パイプ61,62と固定子30との接続について説明する。冷却パイプ61,62は一方が往管であり、他方が戻り管である。冷却パイプ61,62の端部は第2の継ぎ手である継ぎ手63にろう付け等で固定されている。継ぎ手63は固定車軸10内に位置する。固定車軸10の半径方向において、継ぎ手63の一端の冷却水の通路は第3の継ぎ手となる継ぎ手64,66及び継ぎ手65,67を介して固定子30に接続している。継ぎ手63にはL状の通路が二つある。継ぎ手63側の継ぎ手64,65の端部には管用ねじがあり、継ぎ手63にねじ接続している。継ぎ手66,67は継ぎ手64,65、固定子30のそれぞれにフランジによって接続している。
【0014】
固定車軸10には継ぎ手64,65の貫通する貫通穴15と、これに直角方向に向けた貫通穴16とがある。貫通穴16に対向する継ぎ手63の面には凸部63a,63aを設けている。
【0015】
組立方法を説明すると、継ぎ手63を固定したパイプ61,62を固定車軸10内に挿入し、継ぎ手64,65を貫通穴15から挿入して、継ぎ手63にねじこむ。この時、貫通穴16から凸部63aを支持する差さえ金具を挿入し、継ぎ手63の凸部63aを支持する。これに寄れば、継ぎ手63への継ぎ手64,65のねじ接続を容易に行なうことができるものである。凸部63aは凹部でもよい。
【0016】
尚、電線51、座52、継ぎ手63等を設置する際には回転体42、継ぎ手46車輪21は設置していない。電線51、継ぎ手63等を設置した後、これらを所定位置に組み立てる。
【0017】
【発明の効果】
本発明によれば、中空の固定車軸内の冷却媒体のパイプの固定作業を容易に行なうことができるものである。

BACKGROUND OF THE INVENTION
The present invention relates to a bogie for a railway vehicle in which a stator of an electric motor is fixed to an axle.
[0002]
[Prior art]
Japanese Patent Laid-Open No. 07-9993 discloses a bogie for a railway vehicle in which a stator of an electric motor is fixed to an axle. In this type of carriage, the cooling of the stator becomes a problem, so that cooling air is blown from the axial end of the stator.
[0003]
[Problems to be solved by the invention]
In the above prior art, cooling is performed with air, and the efficiency is poor. Moreover, although it is not shown about the electricity supply means to the stator of an electric motor, it is thought that an electric wire is connected to the axial direction edge part of a stator similarly to cooling ventilation.
[0004]
In the present invention, a hollow shaft is used as an axle, and a cooling liquid pipe and an electric wire are arranged inside the axle from an axial end of the axle. In this case, it is necessary to bend the pipe and the electric wire in the radial direction from the axle at the axial end of the stator.
[0005]
An object of the present invention is to make it possible to easily fix a cooling pipe.
[0006]
[Means for Solving the Problems]
The above purpose is
A stator provided on the outer periphery of a hollow fixed axle, a rotor provided on the outer periphery thereof, and a joint connecting the rotor and wheels provided on both ends in the axial direction;
A second joint disposed within the fixed axle and secured to the end of the cooling medium pipe;
A third joint projecting radially from the second joint and connected to the stator, and connecting the third joint and the second joint with a screw;
Can be achieved.
[0007]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the drive part of the cart of one embodiment of the present invention will be described with reference to FIGS.
[0008]
Wheels 21 and 21 are installed on both ends of a hollow fixed axle 10 penetrating both ends via bearings 20. The fixed axle 10 is a hollow shaft that penetrates both ends. A stator 30 is fixed to the outside of the central portion in the longitudinal direction of the fixed axle 10. There is a rotor 40 on the outer periphery of the stator 30. The rotor 40 is attached to the inside of a cylindrical rotating body 42. Both ends of the rotating body 42 are fixed to the side surface of the wheel 21 via a hollow joint 46. The joint 46 is detachably attached to the wheel 21 and the rotating body 42 by bolts (not shown). The stator 30 and the rotor 40 constitute an electric motor.
[0009]
The electric wire 51 is inserted from one end of the hollow fixed shaft 10, is bent in the radial direction near the stator 30, and is connected to the axial end of the stator 30. The fixed shaft 10 is provided with a through hole 11 through which the electric wire 51 passes in the radial direction. The through hole 11 penetrates the fixed shaft 10 in the radial direction.
[0010]
2 and 3, a through hole 11 is passed through a rectangular or rod-like seat 52 that fixes the electric wire 51. Both ends of the seat 52 are fixed to a seat outside the fixed axle (not shown) or a seat 54 at the axial end of the stator 30 with bolts (not shown). The electric wire 51 is coupled to the seat 52 with a string 53 (consisting of a wire coated with resin, a resin band, or the like). The seat 52 is a wire support.
[0011]
According to this, since the electric wire 51 is fixed between the shaft end of the fixed axle 10 and the stator 30, even if the electric wire 51 is pulled from the shaft end side of the fixed axle, the electric wire 51 is disconnected from the stator 30. Does not occur.
[0012]
In the assembling method, after the electric wire 51 is taken out from the through hole 11 to the outside of the fixed axle 10, the electric wire 51 is fixed to the central portion in the longitudinal direction of the seat 52 with the string 53. Next, the seat 52 is put into the fixed axle 10 and both ends of the seat 52 are fixed to the seat 54. According to this, the electric wire 51 is fixed in the fixed axle 10. For this reason, compared with the case where it fixes on the outer side of the fixed axle 10, when the electric wire 51 is pulled from the axial end side of the fixed axle 10, the electric wire 51 does not contact the corner | angular part of the through-hole 11, etc. Is generated.
[0013]
The connection between the cooling pipes 61 and 62 and the stator 30 will be described with reference to FIGS. One of the cooling pipes 61 and 62 is an outward pipe, and the other is a return pipe. The ends of the cooling pipes 61 and 62 are fixed to a joint 63 which is a second joint by brazing or the like. The joint 63 is located in the fixed axle 10. In the radial direction of the fixed axle 10, the cooling water passage at one end of the joint 63 is connected to the stator 30 via joints 64 and 66 and joints 65 and 67 serving as third joints . The joint 63 has two L-shaped passages. At the ends of the joints 64 and 65 on the joint 63 side, there are pipe screws, which are connected to the joint 63 by screws. The joints 66 and 67 are connected to the joints 64 and 65 and the stator 30 by flanges.
[0014]
The fixed axle 10 has a through hole 15 through which the joints 64 and 65 pass, and a through hole 16 oriented in a direction perpendicular to the through hole 15. Convex portions 63 a and 63 a are provided on the surface of the joint 63 facing the through hole 16.
[0015]
Explaining the assembling method, the pipes 61 and 62 to which the joint 63 is fixed are inserted into the fixed axle 10, the joints 64 and 65 are inserted from the through hole 15, and screwed into the joint 63. At this time, a metal fitting is inserted even to support the convex portion 63a from the through hole 16, and the convex portion 63a of the joint 63 is supported. If it approaches to this, the screw connection of the joints 64 and 65 to the joint 63 can be performed easily. The convex portion 63a may be a concave portion.
[0016]
In addition, when installing the electric wire 51, the seat 52, the joint 63, etc., the rotating body 42 and the joint 46 wheels 21 are not installed. After installing the electric wire 51, the joint 63, etc., they are assembled at predetermined positions.
[0017]
【The invention's effect】
According to the present invention, it is possible to easily fix the cooling medium pipe in the hollow fixed axle.
