このようなリンク式操舵装置を備えた操舵台車の場合、操舵しない台車と比較して軸箱と台車枠を前後、左右方向に適度な剛性で支持するための部品点数が多くなるという課題を有している。   In the case of a steering cart provided with such a link type steering device, there is a problem that the number of parts for supporting the axle box and the cart frame in the front-rear and left-right directions with appropriate rigidity is increased compared to a cart that is not steered. doing.

しかしながら、特許文献１で開示された操舵装置は勿論、従来の何れのリンク式操舵装置も、操舵装置の部品点数の削減について考慮されたものは無かった。   However, none of the conventional link type steering devices as well as the steering device disclosed in Patent Document 1 has been considered for reducing the number of parts of the steering device.

特許第３４４８４４５号公報Japanese Patent No. 3448445

本発明が解決しようとする課題は、従来のリンク式操舵装置では、操舵装置の部品点数の削減について考慮されたものは無かったという点である。   The problem to be solved by the present invention is that no conventional link type steering apparatus has been considered for reducing the number of parts of the steering apparatus.

本発明は、リンク式操舵台車の部品点数を削減し、操舵台車をより低コストで実現することを目的としている。   An object of the present invention is to reduce the number of parts of a link type steering carriage and to realize the steering carriage at a lower cost.

すなわち、本発明の鉄道車両用操舵台車の操舵装置は、
台車部に回転自在に連結される操舵てこに対して、操舵する輪軸を支持する軸箱部に回転自在に連結されるモノリンクと車体部に回転自在に連結される連結リンクを、それぞれ回転自在に連結して前記輪軸を操舵可能に構成したモノリンク式操舵台車の操舵装置において、
軸箱体を前記操舵てことして使用することを最も主要な特徴としている。 That is, the steering device for a railway vehicle steering carriage of the present invention is:
For the steering lever that is rotatably connected to the carriage, the monolink that is rotatably connected to the axle box that supports the wheel shaft to be steered and the link that is rotatably connected to the vehicle body are respectively rotatable. In a steering device for a monolink type steering carriage configured to be capable of steering the wheel shaft by being connected to
The main feature is that the shaft box body is used by being steered.

本発明の操舵台車の操舵装置は、軸箱体を操舵てことして使用するので、操舵てこを削減することができる。   Since the steering device for a steering cart of the present invention is used by steering the axle box body, the steering lever can be reduced.

本発明によれば、軸箱体を操舵てことして使用するので、操舵てこを削減することができ、軽量化に加えてコスト削減をも図れる。   According to the present invention, since the axle box is used by being steered, the steering lever can be reduced, and the cost can be reduced in addition to the weight reduction.

本発明では、リンク式操舵台車の部品点数を削減するという目的を、軸箱体を操舵てことして使用することで実現した。   In the present invention, the object of reducing the number of parts of the link type steering carriage is realized by steering the axle box body.

以下、本発明を実施するための形態例を、図１及び図２を用いて説明する。
図１及び図２は頂上ばね式軸箱支持装置を備えたモノリンク式操舵台車に本発明を適用した場合の図である。 Hereinafter, exemplary embodiments for carrying out the present invention will be described with reference to FIGS. 1 and 2.
FIG. 1 and FIG. 2 are diagrams when the present invention is applied to a monolink type steering cart provided with a top spring type axle box support device.

先に説明したリンク式操舵装置を構成する操舵てこ、操舵リンク、連結リンクの主要３部材と、それらを結合する球面ブッシュ、ゴムブッシュ等は、輪軸を適切な操舵てこ比で操舵するためには欠かせない要素である。   The three main members of the steering lever, steering link, and connecting link that make up the link type steering device described above, and the spherical bush, rubber bush, etc. that connect them are used to steer the wheel shaft at an appropriate steering lever ratio. It is an indispensable element.

ところで、モノリンク式軸箱支持装置の場合、車両の前後進方向（以下、前後方向という。）の荷重は、軸箱と台車枠を繋ぐモノリンクで伝えており、軸箱と台車の前後方向支持はモノリンクの取り付け位置で規定される。   By the way, in the case of a monolink type axle box support device, the load in the vehicle forward / rearward direction (hereinafter referred to as the longitudinal direction) is transmitted by a monolink that connects the axle box and the carriage frame, and the longitudinal direction of the axle box and the carriage is Support is defined at the location of the monolink.

従って、モノリンク式軸箱支持装置を有する操舵台車では、このモノリンクを操舵リンクとして活用している。このモノリンクを操舵リンクとして活用した操舵台車をモノリンク式操舵台車と称している。   Therefore, in a steering carriage having a monolink type axle box support device, this monolink is utilized as a steering link. A steering cart using this monolink as a steering link is referred to as a monolink type steering cart.

一方、モノリンク式軸箱支持装置における車両幅方向（以下、左右方向という。）の荷重は、軸箱と台車枠ばね帽間に配置され、軸箱の上部に突出させた角部材の外周部に嵌め込んだ弾性体で負担している。   On the other hand, the load in the vehicle width direction (hereinafter referred to as the left-right direction) in the monolink-type axle box support device is arranged between the axle box and the bogie frame spring cap, and the outer peripheral portion of the corner member that protrudes from the upper part of the axle box. It is borne by the elastic body fitted into the.

発明者は、モノリンク式軸箱支持装置の左右方向支持のための弾性体を外周部に嵌め込む角部材を操舵てことして使用することを考えた。この軸箱の上部に突出させた角部材を操舵てことして使用すれば、リンク式操舵装置の主要３要素のうちの一つを既存のモノリンク式軸箱支持装置の軸箱体に兼ねさせることができる。   The inventor considered to use by steering a square member that fits an elastic body for supporting the monolink-type axle box support device in the left-right direction into the outer peripheral portion. If the corner member protruded from the upper part of the axle box is steered and used, one of the three main elements of the link type steering device can be used as the axle box body of the existing monolink type axle box support device. Can do.

本発明の操舵台車の操舵装置は、発明者の上記考えに基づいてなされたものであり、例えば図１に示すような構成である。   The steering device for a steering cart of the present invention is made based on the above-mentioned idea of the inventor, and has a configuration as shown in FIG. 1, for example.

２１は操舵リンクとしての作用をも奏するモノリンクであり、一方端は台車枠１に他方端はその上部に角部材２ａを突出状に設けた軸箱２に、球面ブッシュ、ゴムブッシュ等を介して夫々回転自在に連結されている。   Reference numeral 21 denotes a monolink that also functions as a steering link. One end is a bogie frame 1 and the other end is a shaft box 2 provided with a protruding angular member 2a on the upper portion thereof, via a spherical bush, a rubber bush, or the like. Are connected to each other in a freely rotatable manner.

本発明では、台車枠１と軸箱２間を前後方向に結合する前記モノリンク２１を、図１に示すように車軸６ａに対して例えば下方向にオフセットして取り付ける。このオフセット量Ｌ1やオフセットの向きは、目標とする操舵てこ比（Ｌ2：Ｌ1、図１参照）によって決定する。   In the present invention, the monolink 21 that connects the carriage frame 1 and the axle box 2 in the front-rear direction is attached to the axle 6a, for example, by being offset downward, as shown in FIG. The offset amount L1 and the direction of the offset are determined by a target steering lever ratio (L2: L1, see FIG. 1).

また、本発明では、前記角部材２ａの上端を台車枠１のばね帽１ａより突出させ、この突出させた上端部に、例えばボルスタ３に一端側を回転自在に連結した連結リンク２２の他端側を回転自在に連結し、軸箱２自体を操舵てことして作用するように構成している。なお、この連結リンク２２の両端の回転自在な連結部は、モノリンク２１の両端部と同様、球面ブッシュ、ゴムブッシュ等が介在されている。   Further, in the present invention, the upper end of the corner member 2a is protruded from the spring cap 1a of the carriage frame 1, and the other end of the connecting link 22 in which one end side is rotatably connected to the protruded upper end portion, for example, the bolster 3. The sides are rotatably connected, and the axle box 2 itself is steered to act. In addition, a spherical bush, a rubber bush, etc. are interposed in the rotatable connection part of both ends of this connection link 22 like the both ends of the monolink 21.

上記構成の本発明の操舵装置では、操舵装置をスムーズに動作させるため、軸箱２の角部材２ａと台車枠１間の前後方向を柔らかく支持することが望ましい。そのためには、軸箱２と台車枠１の支持を上下荷重用の軸ばね７（コイルスプリング）のみで行い、前後方向及び左右方向の支持は軸ばね７自体が有するばね作用で行うことで実現できる。   In the steering device of the present invention configured as described above, it is desirable to softly support the front-rear direction between the corner member 2a of the axle box 2 and the carriage frame 1 in order to smoothly operate the steering device. For this purpose, the axle box 2 and the carriage frame 1 are supported only by the vertical load shaft spring 7 (coil spring), and the longitudinal and lateral directions are supported by the spring action of the shaft spring 7 itself. it can.

この場合、分岐器通過等で生じる過大な荷重が作用しても干渉等が生じないように、前後方向及び左右方向にストッパを設けるのが望ましい。このストッパとして、図１では、ばね帽１ａの下端内周と軸箱２の上端外周間に隙間ｄを設けておき、前後方向及び左右方向に過大な荷重が作用した場合にこれらばね帽１ａの下端内周と軸箱２の上端外周が当接することでそれ以上移動しないものを示している。   In this case, it is desirable to provide stoppers in the front-rear direction and the left-right direction so that interference does not occur even if an excessive load generated by passing through the branching device is applied. As this stopper, in FIG. 1, a gap d is provided between the inner periphery of the lower end of the spring cap 1a and the outer periphery of the upper end of the axle box 2. The lower end inner periphery and the upper end outer periphery of the axle box 2 are in contact with each other and do not move any further.

しかしながら、前記のようなストッパを設けただけでは、操舵装置が何らかの異常状態により破断した場合は、軸箱２の前後方向の支持剛性が確保されず限界速度が低下する可能性がある。   However, if only the stopper as described above is provided, if the steering device breaks due to some abnormal state, the support rigidity in the front-rear direction of the axle box 2 is not ensured, and the limit speed may be lowered.

従って、限界速度が課題となる比較的高速で走行する車両に本発明を適用する場合は、操舵装置が破断した場合の軸箱２の前後方向の支持剛性を確保するため、図２（ａ）に示すように、軸箱２と台車枠１の間の前後方向に適正剛性を確保するための弾性体２３を設置することが望ましい。   Therefore, when the present invention is applied to a vehicle that travels at a relatively high speed where the critical speed is an issue, in order to ensure the support rigidity in the front-rear direction of the axle box 2 when the steering device is broken, FIG. As shown in FIG. 4, it is desirable to install an elastic body 23 for ensuring appropriate rigidity in the front-rear direction between the axle box 2 and the carriage frame 1.

そのためには、この弾性体２３を、例えば図２（ｂ）に示すように、中心部から左右方向外周側にいくほど前後方向の長さが長くなるようなゴムを積層した構造のものとすれば良い。   For this purpose, for example, as shown in FIG. 2 (b), the elastic body 23 has a structure in which rubber is laminated so that the length in the front-rear direction increases from the center to the outer peripheral side in the left-right direction. It ’s fine.

上記構成の本発明の鉄道車両用操舵台車の操舵装置では、軸箱２を操舵てことして使用するので、操舵てこを削減することができ、軽量化に加えてコスト削減をも図ることができる。   In the steering device for a railway vehicle steering carriage of the present invention configured as described above, since the axle box 2 is used by being steered, the steering lever can be reduced, and the cost can be reduced in addition to the weight reduction.

加えて、従来の操舵装置を有する操舵台車では車体５の質量による軸ばね７のたわみによって操舵装置自体が上下に移動するが、本発明では操舵装置がばね下に設置されるので車体５の質量が変化しても操舵装置自体の高さは変化しない。   In addition, in a steering cart having a conventional steering device, the steering device itself moves up and down due to the deflection of the shaft spring 7 due to the mass of the vehicle body 5, but in the present invention the mass of the vehicle body 5 is installed because the steering device is installed under the spring. Even if changes, the height of the steering device itself does not change.

本発明は上記の例に限らず、請求項に記載された技術的思想の範疇であれば、適宜実施の形態を変更しても良いことは言うまでもない。   The present invention is not limited to the above example, and it goes without saying that the embodiments may be changed as appropriate within the scope of the technical idea described in the claims.

例えば、図１及び図２の例では、連結リンク２２の一方端部をボルスタ３に結合した例を示したが、図３に示すように、車体５に結合しても良い。また、図示省略したが、車体傾斜車両の車体傾斜ばりに結合しても良い。   For example, in the example of FIGS. 1 and 2, the example in which one end portion of the connection link 22 is coupled to the bolster 3 is illustrated, but the coupling link 22 may be coupled to the vehicle body 5 as illustrated in FIG. 3. Although not shown in the figure, it may be coupled to a vehicle body tilting beam of a vehicle body tilting vehicle.

また、本発明の操舵装置の操舵方式は、アクティブ強制操舵方式、半強制操舵方式の何れの方式にも適用可能である。なお、アクティブ強制操舵方式とは、空圧、油圧或いは電動方式のアクチュエータを使用し、外部からエネルギーを投入して制御しながら能動的に輪軸を操舵する方式である。一方、半強制操舵方式とは、車体・台車・輪軸をリンクなどの機械的機構で繋いで、曲線通過時に車体・台車間に発生するボギー変位を駆動力とする方式である。   In addition, the steering system of the steering device of the present invention can be applied to either an active forced steering system or a semi-forced steering system. Note that the active forced steering method is a method of using an air pressure, hydraulic pressure, or electric type actuator to actively steer the wheel shaft while applying energy and controlling from the outside. On the other hand, the semi-forced steering system is a system in which a vehicle body, a carriage, and a wheel shaft are connected by a mechanical mechanism such as a link, and a bogie displacement generated between the body and the carriage when passing a curve is used as a driving force.
