【0011】 [0011]

【課題を解決するための手段】上記の目的を達成するために本発明に係る鉄道車両用一軸台車は、a)左右の車輪が車軸部材を介して回転自在に支持され、前記車輪および前記車軸部材を軸梁を介して支持する台車枠がリンク機構を介して車体に結合される鉄道車両用一軸台車であって、b)前記リンク機構は、前記台車枠側に比べて車体側の幅方向の間隔が広くなるように平面視「略ハ」 Uniaxial bogie for railway vehicles according to the present invention in order to achieve the above object, according to an aspect of the, a) left and right wheels is rotatably supported via an axle member, the wheel and the axle a uniaxial bogie for a railway vehicle bogie frame for supporting the member through the Jikuhari is coupled to the vehicle body via a link mechanism, b) the link mechanism has a width direction of the vehicle body as compared to the truck frame side a plan view so that the distance of a wider "upward toward the inner edge 26b thereof."
の字状に配置され、かつ平面視におけるリンクの前後両端部を結ぶ直線の延長線上の交点が車体の幅方向の中心軸線上に位置する左右のリンクを備え、これらの各リンクは、各一端部が車体もしくは台車枠に対し垂直軸又は垂直方向の上端側が下端側に比べて車軸部材(車軸)中心側へ傾斜した傾斜軸回りに回転可能に軸支され、他端部が台車枠もしくは車体に対し球面軸受等により全方向に揺動自在に結合され、c)左右のリンクの延長線上の前記交点を、前記車体に対する前記台車枠の仮想回転(旋回)中心として旋回可能に構成するとともに、d) Are arranged in the shape, and includes left and right link the intersection of an extension of a straight line connecting the front and rear ends of the link in a plan view is located on the central axis of the body in the width direction, each of these links, each end part is rotatably supported by the tilt axis of the upper end of the vertical axis or vertical direction with respect to the vehicle body or bogie frame is inclined to the axle member (axle) center side than the lower end side and the other end bogie frame or vehicle body together swingably coupled in all directions by the spherical bearing or the like, c) the intersection of an extension of the left and right link pivotally configured as a virtual rotation (turning) center of the bogie frame relative to the vehicle body with respect to, d)
前記各リンクの側面視における両端部を結ぶ直線(作用線)の延長線を、前記各車輪の踏面と軌道との接触点を通るようにしたことを特徴とする。 The extension of the straight line (line of action) connecting the both ends in the side view of the link, characterized in that said to pass through the contact point between the wheel tread and the track of.

【0012】上記の構成を有する本発明に係る一軸台車におけるハの字状の一対のリンクは、上記b)・c)の構成により平面視でリンクの作用線の延長線がほぼ車体の幅方向の中心軸線上(ほぼ車両の幅方向の中心)で交差するから、この交点を一軸台車の仮想旋回中心として旋回する。 [0012] a pair of links of c in the uniaxial truck according to the present invention having the structure shaped above the b) · c) substantially vehicle width direction extension line of action of the link in a plan view the configuration of the since it intersects at the center axis of the (substantially the center in the width direction of the vehicle), turning the intersection as a virtual pivot uniaxial bogie. とくに、先頭に位置する台車では車両のその交点が車軸中心より後ろの位置に生じるようにすれば、 In particular, the carriage located at the head if as the intersection of the vehicle occurs at a position behind the axle center,
車軸の車両進行方向後方位置を中心に旋回することになり、曲線通過性能が向上する。 It will be pivoted about the vehicle traveling direction rear position of the axle, curving performance is improved. 後方に位置する台車の場合には車体を含むプル・プッシュの影響によって、進行方向とは逆の側が旋回中心となってもほとんど影響を受けない。 The influence of the pull-push containing body when the carriage located behind hardly affected even if the reverse side of a turning center to the traveling direction. この構成により、台車旋回用の中心ピンを設ける必要がなく、車体台枠の側梁付近にリンクの連結箇所を設けることができるので、とくに低床式路面電車の場合には、車体と台車との力の受け渡しを車体の幅方向の中心軸線上で行なうよりも、側梁付近で行なうことができ、車体台枠の強度面から有利であり、また旋回中心ピンは中央の1カ所で荷重を負担するのに対して、ハの字状リンクを用いたことにより2カ所に負荷を分散でき、 This configuration, it is not necessary to provide a center pin for bogie pivot, it is possible to provide a connection point of the link in the vicinity of the side beams of the vehicle body underframe, especially in the case of low-floor tram, the car body and the bogie passing than performing the central axis of the vehicle body in the width direction of the force can be performed in the vicinity of the side beams, it is advantageous from the intensity surface of the vehicle body underframe, also the pivot center pin load in one place in the center relative to bear, you can distribute the load in two places by using shaped links Ha,
負担を軽減できる。 Burden can be reduced. さらに上記d)の構成により側面視においてハの字状リンクの車体に対する結合位置と台車枠に対する結合位置とを結ぶ作用線の延長線が、車輪の踏面付近で台車の中心線と交差するように傾斜させているから、レール上の車輪の踏面に前後方向の接線力(具体的には力行や制動力)が作用しても、台車をピッチングさせる力は作用せず、したがって一軸台車を備えているにもかかわらず、ピッチングが確実に防止される。 As further extension line of action connecting the binding position to the binding position and the bogie frame relative to the vehicle body-shaped link c in a side view the structure of the d) intersects the center line of the bogie near the tread surface of the wheel because they are inclined, tangential force in the longitudinal direction on the tread surface of the wheel on the rail even acts (power running and braking force specifically), the force for pitching the carriage does not act, thus comprises a single carriage Despite there, the pitching is reliably prevented.

【0013】また、前記軸梁は前記台車枠の基端寄り下端部に先端側が上下方向に回転自在に軸支され、前記軸梁と前記台車枠の先端寄り間に軸ばねが介装されるとともに、前記台車枠と前記車体間に枕ばねが介装されることが好ましい。 [0013] The shaft beam distal end to the proximal end toward the lower end portion of the truck frame is rotatably supported in the vertical direction, the axial spring is interposed between the tip-sided of the shaft beam and the truck frame together, preferably pillow spring is interposed between the said bogie frame body.

【0014】本例のサスペンションによると側面視におけるリンクの傾斜がなく、リンクをほぼ水平方向に配置しても、軸梁ピンおよび球面軸受によるニーアクションのサスペンションが構成されているために、車輪の踏面に前後方向の接線力(具体的には力行や制動力)が作用しても、その作用力の影響によってわずかに軸ばね荷重などが変化するだけであるから、車輪および車軸部材が車体に対して相対的に大きなピッチング変位を起こすことがない。 The present embodiment is no inclination of the links in the side view according to suspension, be placed on the link in a substantially horizontal direction, in order to the suspension of the knee action by Jikuhari pin and the spherical bearing is constructed, the wheels even acts (power running and braking force specifically) longitudinal tangential force on the tread surface, since such slight axial spring load under the influence of the applied force is only changed, the wheel and the axle member to the vehicle body It is not to cause a relatively large pitching displacement for. 車体は、このように軸ばねによる1次系のサスペンションと枕ばねによる2次系のサスペンションとの2つのサスペンションで上下に揺動自在に支持されるために、乗り心地を良好にできる。 Vehicle body, in order for this is swingably supported vertically by two suspensions the secondary system of the suspension by the primary system of the suspension and pillows spring by the axial spring as can ride well.

【0015】さらに、前記車軸部材には、前記車体の下面から下方に突設したストッパに当接し、前記車体に対する相対旋回範囲を規制する旋回規制部材を設けることができる。 Furthermore, the axle member is in contact with the stopper projecting downward from the lower surface of the vehicle body, it can be provided a pivot restricting member for restricting relative pivoting range relative to the vehicle body.

【0016】この構成により、台車と車体との相対的な旋回範囲(旋回角度)が所定範囲内に規制され、車体に対して台車が必要以上に旋回し過ぎることが防止される。 [0016] With this arrangement, the relative pivoting range of the bogie and the vehicle body (turning angle) is restricted within a predetermined range, thereby preventing the excessively pivoted bogie is unnecessarily with respect to the vehicle body.

【0017】さらにまた、前記車軸部材と前記車体下面との間に、前記車体に対する幅方向の相対変位を緩衝する緩衝手段を介設することができる。 [0017] Furthermore, between the vehicle body lower surface and the axle member can be interposed a buffer means for buffering the relative displacement in the width direction relative to the vehicle body.

【0018】この構成により、車両の走行時に車体が横(幅)方向に揺れるのが緩衝手段で緩衝され、車体の横揺れが抑制される。 [0018] With this configuration, the vehicle body during traveling of the vehicle is a sideways motion to (width) direction is buffered by buffer means, rolling of the vehicle body is suppressed.

【0019】前記車軸部材を幅方向の中央部分で下向きに凹状に形成して非回転の車軸とし、前記左右の車輪を該車軸部材の両側にそれぞれ回転自在に支持することができる。 [0019] The axle member at a central portion in the width direction and formed in a concave shape downwardly and non-rotating axle, the wheels of the left and right can be rotatably supported on both sides of the axle member.

【0020】この構成により、左右の車輪が幅方向の内方へ押圧されることがあっても車軸部材により、車輪が内方へ移動するのが阻止される。 [0020] With this arrangement, the left and right axles member even if the wheel is pressed inwardly in the width direction, the wheel is moved inward is prevented. しかも、車軸部材は下向き凹状に形成されているから、床面を低くしても車軸部材に干渉せず、100%低床の床面が可能になる。 Moreover, the axle member from being formed on the downwardly concave shape, even with a lower floor without interfering with the axle member allows floor 100% low-floor.

【0021】前記軸梁を「略ロ」の字状の環状体に形成し、この車軸を前記軸梁の両側の各側辺の外側から内方に貫通して軸受等を介して回転自在に支持し、車軸の内端に車輪を一体回転可能に取着して片持ち支持することができる。 [0021] The shaft forms a beam to the shape of the annulus "substantially square", rotatably this axle via a bearing or the like through the outside inward in each side of each side of the shaft beam supporting the wheel to the inner end of the axle can be integrally rotatably attached to cantilevered.

【0022】この構成により、軸梁を広くできるために、両側の車輪をそれぞれ片持ち支持しても十分に強度を保てるとともに、とくに連接車両の連接箇所に設けるのに好適である。 [0022] With this arrangement, in order to be able to widen the Jikuhari, with maintained sufficiently strength even on both sides of the wheel and cantilevered respectively, it is suitable for particularly provided articulation points of the articulated vehicle.

【0023】また、前記左右の車輪の外側回転中心部を、前記軸梁の基端側枢支部(軸梁ピン)付近に搭載したモーターにその先端側に配置した減速機を介して接続することができる。 Further, the outer rotation center of the left and right wheels, be connected through a reduction gear disposed on the tip side equipped with a motor in the vicinity of the base end side pivot section of said shaft beam (Jikuhari pin) can.

【0024】この構成により、モーターを振動系のばね間ないしばね上の質量として配分できるから、ばね下の荷重が軽減され、軌道や周辺に与える振動エネルギーを小さくするとともに、モーター質量によってばね間重量を増加することができるから、乗り心地が向上し、モーターへの加振力も削減される。 [0024] With this arrangement, since the motor can be distributed as a spring between or mass on the spring of the vibration system, the load of the unsprung is reduced, thereby reducing the vibration energy applied to the track and around the spring between the weight by the motor mass since it is possible to increase, improve ride comfort, vibration force to the motor is also reduced.

【0025】さらにまた、前記球面軸受に代えて、ユニバーサルジョイント又は弾性体を使用してもよい。 [0025] Furthermore, instead of the spherical bearing may be used a universal joint or a resilient body.

【0026】ユニバーサルジョイント又は弾性体を使用しても、リンクとの結合部において同様の作用が働く。 [0026] Also using the universal joint or an elastic body, it acts the same function at the junction between the link.

1は側面視において前後両端の支軸24・25の中間点を結ぶ直線(作用線)の延長線Sが車輪14の踏面とレール9との接触点を通るように構成されている。 1 is constructed as an extension S of the straight line (line of action) connecting the midpoint of the opposite ends of the support shaft 24, 25 back and forth in a side view passes through contact points between the tread and the rail 9 of the wheel 14. なお、 It should be noted that,
球面軸受24に代えて、ユニバーサルジョイント又はゴムなどの弾性体を用いて全方向の揺動を許容して連結することができる。 Instead of the spherical bearing 24 can be coupled to permit a swinging of all directions by using an elastic member such as universal joint or rubber.

【0035】さらに、図5(a)に示すように車軸部材13の長手方向のほぼ中間位置前面において、一対のストッパー26を間隔をあけて前方へ突設するとともに、 Furthermore, in the longitudinal direction of the substantially middle position the front axle member 13 as shown in FIG. 5 (a), while projecting forwardly at intervals a pair of stoppers 26,
これらのストッパー26・26間に車体3の下面より旋回範囲(旋回角度)を規制するための規制部材27を下向けに突設する。 Lower surface from pivoting range of the vehicle body 3 between these stoppers 26, 26 of the regulating member 27 for regulating the (turning angle) to project below for. また車軸部材13の長手方向のほぼ中間位置後面において、伸縮自在なダンパー28の一端を後方へ突設したブラケット29の先端に連結し、ダンパー28の他端を車体3の下面より下向けに突設したブラケット30に連結している。 Butt In After approximately an intermediate position plane in the longitudinal direction of the axle member 13, one end of telescopic dampers 28 connected to the distal end of the bracket 29 which projects rearwardly and consumer below the lower surface of the vehicle body 3 and the other end of the damper 28 It is connected to set the bracket 30.

【0036】このようにして本例の一軸台車10が構成されるが、連接車両1の右端および単一車両1の右端の一軸台車10'は、一軸台車10の各構成部材と前後方向が対称に配置されるだけで、基本的に共通する。 [0036] This way uniaxial carriage 10 of the present embodiment is configured in the rightmost uniaxial carriage 10 at the right and a single vehicle 1 articulated vehicle 1 ', the constituent members and the longitudinal direction of the uniaxial carriage 10 is symmetrical only it is arranged in basically common. また連接車両1の連接箇所に配置される一軸台車10”は、 The uniaxial carriage 10 arranged at the connecting point of the articulated vehicle 1 "
一軸台車10と共通のものを使用することができるが、 It can be used in common as the single carriage 10,
図18のように軸梁41を「略ロ」の字状の環状体に形成した一軸台車10−3(図8参照)を使用するのが好ましい。 Preference is given to using a uniaxial carriage 10-3 (see FIG. 8) forming a Jikuhari 41 shaped annulus "substantially square" as shown in Figure 18.

【0037】図6には本例の一軸台車10が車体3に対し相対的に左旋回した状態を示すが、車軸部材13の近傍の仮想回転中心点Oを旋回中心として輪軸13・14 [0037] While FIG. 6 illustrates a state in which the uniaxial carriage 10 of this embodiment has a relatively left turn to the vehicle body 3, axle 13, 14 as the turning center virtual rotational center point O in the vicinity of the axle member 13
および台車枠11等が一体的に旋回する。 And the truck frame 11 or the like is pivoted integrally. このとき、ダンパー28が圧縮・伸長されるとともに、横方向の振動吸収に作用する。 At this time, the damper 28 is compressed and decompression, acting on the vibration absorbing lateral. また、規制部材27が右側のストッパー26に当接し、所定の旋回角度以上に旋回することが阻止される。 Further, the regulating member 27 abuts on the right side of the stopper 26, to be pivoted over a predetermined turning angle is prevented. 同時に左右のリンク21の先端位置に対し球面軸受24を介して台車枠11の二股状のブラケット22が変位するとともに、枕ばね17が変形する。 With bifurcated bracket 22 of the truck frame 11 is displaced through the spherical bearing 24 relative to the distal end position of the left and right links 21 simultaneously, pillows spring 17 is deformed. このようにして、曲線状のレール9に沿って一軸台車10が旋回し、レール9の直線部に進入すると元の状態に旋回して戻る。 In this way, the single carriage 10 pivots along a curved rail 9 and enters the straight portion of the rail 9 pivots back to its original state.

【0038】ところで、図13は本例の一軸台車10を模式的に現した側面図である。 By the way, FIG. 13 is a side view of a single truck 10 of the present embodiment were expressed schematically. 同図に示すように、軸梁12の先端部間にて、車軸部材13に回転自在に支持された一対の車輪14および車輪14がそれぞれ回転自在に支持され、また台車枠11に対し軸梁ピン12aを介して軸梁12が上下方向に揺動可能に支持され、軸梁1 As shown in the drawing, in between the ends of the Jikuhari 12, a pair of wheels 14 and wheel 14 which is rotatably supported on an axle member 13 is rotatably supported, respectively, also with respect to the bogie frame 11 Jikuhari Jikuhari 12 via the pin 12a is swingably supported in the vertical direction, Jikuhari 1
2と台車枠11間の軸ばね16により1次系のサスペンションが構成されている。 The axial spring 16 between 2 and truck frame 11 is the primary system of the suspension is constructed. また、台車枠11は球面軸受24およびハの字状リンク21を介して車体3に結合され、この状態で台車枠11は球面軸受24を支点として上下方向に揺動可能に支持され、台車枠11と車体3との枕ばね17により2次系のサスペンションが構成されている。 Further, the bogie frame 11 is coupled to the vehicle body 3 through the shaped link 21 of the spherical bearing 24 and Ha, bogie frame 11 in this state is swingably supported in the vertical direction the spherical bearing 24 as a fulcrum, the bogie frame 11 and the pillow spring 17 between the vehicle body 3 secondary system of the suspension is formed. 車体3は、このように軸ばね16による1次系のサスペンションと枕ばね17による2次系のサスペンションとの2つのサスペンションで上下に揺動自在に支持されるために、乗り心地が良好である。 Body 3, to this is swingably supported vertically by two suspension a secondary system of a suspension by the primary system of the suspension and pillows spring 17 by axial spring 16 as, ride quality is good .

【0039】さらに、本例のサスペンションによると側面視におけるリンク21の傾斜がなく、リンク21をほぼ水平方向に配置しても、軸梁ピン12aおよび球面軸受24によるニーアクションのサスペンションが構成されているために、車輪14の踏面に前後方向の接線力(具体的には力行や制動力)が作用しても、その作用力の影響によってわずかに軸ばね荷重などが変化するだけであるから、車輪14および車軸部材13が車体3に対して相対的に大きなピッチング変位を起こすことがない。 [0039] Further, there is no inclination of the links 21 in the side view according to the suspension of the present example, be arranged link 21 in a substantially horizontal direction, it is constructed the suspension of the knee action by Jikuhari pins 12a and the spherical bearing 24 to have, even acts (power running and braking force specifically) longitudinal tangential force on the tread surface of the wheel 14, since only slightly like the axial spring load is varied by the influence of the applied force, wheels 14 and the axle member 13 does not cause relatively large pitching displaced with respect to the vehicle body 3.

【0040】しかも、側面視においてハの字状リンク2 [0040] In addition, the letter of c in a side view like link 2
1の車体3に対する結合位置25と台車枠11に対する結合位置24とを結ぶ作用線の延長線Sが、車輪14の踏面付近で台車10の中心線と交差するように傾斜させているから、レール9上の車輪14の踏面に前後方向の接線力(具体的には力行や制動力)が作用しても、台車10をピッチングさせる力は作用しない。 Extension S line of action connecting the coupling position 24 to the binding position 25 and truck frame 11 for a vehicle body 3, because they inclined so as to intersect with the center line of the carriage 10 in the vicinity tread surface of the wheel 14, rail even acts (power running and braking force specifically) longitudinal tangential force on the tread surface of the wheel 14 on 9, the force for pitching the carriage 10 does not act.

【0041】一方、ハの字状の一対のリンク21は、平面視でリンク21の作用線の延長線Pがほぼ車体の幅方向の中心軸線上(ほぼ車両の幅方向の中心)で交差するから、この交点Oを一軸台車10の仮想旋回中心として旋回する。 On the other hand, a pair of links 21 shaped Ha intersect at the center axis in the width direction of the substantially vehicle extension P of the line of action of the link 21 in a plan view (substantially the center in the width direction of the vehicle) from turning the intersection O as a virtual pivot uniaxial carriage 10. この構成により、台車10には旋回用の中心ピンを設ける必要がなく、台車枠11の側梁11c付近にリンク21の連結箇所を設けることができる。 This configuration, it is not necessary to provide a center pin for pivoting the carriage 10 can be in the vicinity of the side beam 11c of the bogie frame 11 provided with connection points of the link 21. とくに、上記した低床式路面電車1の場合には、車体3と台車10との力の受け渡しを車体3の幅方向の中心軸線L In particular, in the case of low-floor trams 1 described above, the central axis passing force in the width direction of the vehicle body 3 of the vehicle body 3 and the carriage 10 L
上で行なうよりも、側梁11c付近で行なう方が台車枠11の強度面から有利である。 Than do above, who performed in the vicinity of the side beam 11c is advantageous from the intensity plane of the bogie frame 11. 車体3の台枠の構成においても、低床式路面電車では車体台枠の側梁に強度を持たす構造でないと低床化に不利であり、台車からの力の伝達が車体中央でなく、両方の側梁付近に伝達されることは有利である。 In the structure of the underframe of the vehicle body 3, lower in the bed tram is not a structure that Motas strength to side beams of the vehicle body underframe disadvantageous to low-floor, rather than transfer the vehicle center of force from the carriage, both is transmitted to the vicinity of the side beams is advantageous. また、旋回中心ピンは中央の1カ所で荷重を負担するのに対して、ハの字状リンク21を用いたことにより2カ所に分散でき、台車枠11および車体台枠の負担を軽減できる。 Also, the turning center pin against to bear the load in one place in the center, by using the shaped link 21 Ha can be dispersed in two places, thereby reducing the burden on the bogie frame 11 and the vehicle body underframe.

【0042】さらに、図1に示す2両編成などの連接車両1では、車両1間の連接箇所に一軸台車10の車軸部材13を配置することにより、各車両1のスペースを有効に使用できる。 [0042] Furthermore, the articulated vehicle 1, such as 2-car train shown in FIG. 1, by arranging the axle member 13 uniaxial carriage 10 to connecting portion between the vehicle 1, the space of the vehicle 1 can be effectively used.

【0056】以上に本発明の一軸台車の実施例を示したが、本発明は低床式路面電車に限らず、床の位置が高い一般的な路面電車や軽量化を図った鉄道車両に適用できることは言うまでもない。 [0056] mentioned example uniaxial bogie of the present invention above, the present invention is not limited to the low-floor trams, applied to a railway vehicle floor positions aiming high common tram and weight can it is needless to say.

【0057】 [0057]

【発明の効果】以上説明したことから明らかなように、 [Effect of the Invention] As apparent from the above description,
本発明に係る鉄道車両用一軸台車には、次のような優れた効果がある。 Uniaxially bogie for a railway vehicle according to the present invention has the following excellent effects.

【0058】(1)100%低床式の路面電車に好適で連接台車にも適用可能であり、しかも構造が簡単で軽量で、一軸でピッチングを防止でき、乗り心地が良好になる。 [0058] (1) it is also applicable to the preferred in Jacobs bogie tram 100% low floor type, yet is a simple and lightweight construction, it is possible to prevent pitching uniaxial, ride is improved.

【0059】(2)平面視(水平面内)でリンクの作用線の延長線が車軸部材の幅方向のほぼ中心位置で交差するから、この交点を一軸台車の仮想旋回中心として旋回することにより、台車旋回用の中心ピンを設ける必要がなく、台車枠の側梁付近にリンクの連結箇所を設けることができる。 [0059] (2) from an extension line of action of the link in a plan view (horizontal plane) intersect at substantially the center position in the width direction of the axle member by pivoting the intersection as a virtual pivot uniaxial bogie, it is not necessary to provide a center pin for bogie turning can be provided a connecting point of the link in the vicinity of the side beam of the bogie frame. したがって、とくに低床式路面電車の場合に、車体と台車との力の受け渡しを車体の幅方向の中心軸線上で行なうよりも、側梁付近で行なうことができ、 Therefore, particularly in the case of low-floor trams, than it transfers force between the vehicle body and the bogie at the center axis of the vehicle body in the width direction it can be performed in the vicinity of the side beams,
台車枠および車体台枠の強度面から有利であり、また旋回中心ピンは中央の1カ所で荷重を負担するのに対して、ハの字状リンクを用いたことにより2カ所に負荷を分散でき、負担を軽減できる。 Is advantageous from the intensity plane of the bogie frame and the vehicle body mount frame, also turning center pin for to bear the load in one place in the center, can distribute the load to the two positions by using a shaped link Ha , it is possible to reduce the burden.

【0060】また側面視においてハの字状リンクの車体に対する結合位置と台車枠に対する結合位置とを結ぶ作用線の延長線が、車輪の踏面付近で台車の中心線と交差するように傾斜させているから、レール上の車輪の踏面に前後方向の接線力(具体的には力行や制動力)が作用しても、台車をピッチングさせる力は作用せず、したがって一軸台車を備えているにもかかわらず、ピッチング変位が防止される。 [0060] Also the extension line of action connecting the binding position to the binding position and the bogie frame relative to the vehicle body-shaped link c in a side view, and inclined so as to intersect with the center line of the bogie near the tread surface of the wheel since there, the tangential force in the longitudinal direction on the tread surface of the wheel on the rail even acts (power running and braking force specifically), the force for pitching the carriage does not act, therefore also has a single carriage regardless, pitching displacement is prevented.

【0061】(2)軸梁は台車枠の基端寄り下端部に先端側が上下方向に回転自在に軸支され、軸梁と台車枠の先端寄り間に軸ばねが介装されるとともに、台車枠と車体間に枕ばねが介装されることにより、側面視におけるリンクの傾斜がなく、リンクをほぼ水平方向に配置しても、軸梁ピンおよび球面軸受によるニーアクションのサスペンションが構成さているために、車輪の踏面に前後方向の接線力(具体的には力行や制動力)が作用しても、その作用力の影響によってわずかに軸ばね荷重などが変化するだけであるから、車輪および車軸部材が車体に対して相対的に大きなピッチング変位を起こすことがない。 [0061] (2) Jikuhari the distal end side is rotatably supported in the vertical direction proximally lower portion of the truck frame, with the shaft spring is interposed between the tip-sided of Jikuhari and bogie frame, the bogie by pillow spring is interposed between the frame and the vehicle body, there is no inclination of the links in side view, be placed on the link in a substantially horizontal direction, the suspension of the knee action by Jikuhari pin and the spherical bearing is constructed for, even acts (power running and braking force specifically) longitudinal tangential force on the tread surface of the wheel, since it is only slightly, such as axial spring load is varied by the influence of the applied force, the wheel and axle member is prevented from causing a relatively large pitching displaced with respect to the vehicle body. したがって、車体は、このように軸ばねによる1 Thus, the vehicle is by this way the axial spring 1
次系のサスペンションと枕ばねによる2次系のサスペンションとの2つのサスペンションで上下に揺動自在に支持されるために、乗り心地が良好である。 To swing is rotatably supported up and down two suspension with the following system of suspension and pillows secondary system of a suspension by the spring, ride comfort is good.

【0062】(3)車軸部材には、車体の下面から下方に突設したストッパに当接し、車体に対する相対旋回範囲を規制する旋回規制部材を設けることにより、台車と車体との相対的な旋回範囲(旋回角度)が所定範囲内に規制され、車体に対して台車が必要以上に旋回し過ぎることが防止される。 [0062] (3) on the axle member is in contact with the stopper which projects from the lower surface of the vehicle body downward, by providing a pivot restricting member for restricting relative pivoting range to the vehicle body, the relative pivoting between the bogie and the vehicle body range (turning angle) is restricted within a predetermined range, thereby preventing the truck too pivot than necessary with respect to the vehicle body.

【0063】(4)車軸部材と車体下面との間に、車体に対する幅方向の相対変位を緩衝する緩衝手段を介設することにより、車両の走行時に車体が横方向に揺れるのが緩衝手段で緩衝され、車体の横揺れを抑制できる。 [0063] (4) between the axle member and the vehicle body lower surface, by interposed a buffer means for buffering the relative displacement in the width direction relative to the vehicle body, the vehicle body during traveling of the vehicle in shake a buffer means in the transverse direction buffered, it is possible to suppress the vehicle body roll.

【0064】(5)前記車軸部材を幅方向の中央部分で下向きに凹状に形成して非回転の車軸とし、前記左右の車輪を該車軸部材の両側にそれぞれ回転自在に支持することにより、左右の車輪が幅方向の内方へ押圧されることがあっても車軸部材により、車輪が内方へ移動するのが阻止される。 [0064] (5) by the axle member at a central portion in the width direction and formed in a concave shape downwardly and non-rotating axle, for rotatably supporting respective wheels of the right and left sides of the axle member, left and right the axle member even if the wheel is pressed inwardly in the width direction of, is prevented that the wheels are moved inwardly. しかも、車軸部材は下向き凹状に形成されているから、床面を低くしても車軸部材に干渉せず、 Moreover, the axle member from being formed on the downwardly concave shape, even with a lower floor without interfering with the axle member,
100%低床の床面が可能になる。 Allowing the floor of the 100% low-floor.

【0065】(6)軸梁を「略ロ」の字状の環状体に形成し、車軸を前記軸梁の両側の各側辺の外側から内方に貫通して軸受等を介して回転自在に支持し、車軸の内端に車輪を一体回転可能に取着して片持ち支持すれば、左右の車輪の内側間に位置する部材がなく、車体の低床部と干渉していた部分を広くできる。 [0065] (6) Jikuhari was formed into shaped annulus "substantially square", rotatably via a bearing or the like axle from the outside of both sides of each side of the shaft beam penetrates inwardly supported on, if integrally rotatably attached to cantilever supporting a wheel on the inner end of the axle, there is no member located between the inside of the left and right wheels, the portion not interfere with the body of the low floor section It can be widened. また、車軸を遠巻きにして強度部材を配置できるために、両側の車輪をそれぞれ片持ち支持しても十分に強度および剛性を保てるとともに、とくに連接車両の連接箇所に配置する一軸台車として最適である。 Further, in order to be able to place the strength member and the axle afar, with maintained sufficiently strength and rigidity even if both sides of the wheel and cantilevered respectively, are optimal single truck particularly placed articulation point of the articulated vehicle .

【0066】(7)左右の車輪の外側回転中心部を、軸梁の基端側枢支部(軸梁ピン)付近に搭載したモーターにその先端側に配置した減速機を介して接続することにより、モーターを振動系のばね間ないしばね上の質量として配分できるから、ばね下の荷重が軽減され、軌道や周辺に与える振動エネルギーを小さくするとともに、乗り心地が向上し、モーターへの加振力も削減できる。 [0066] (7) the outer rotating center of the left and right wheels, by connecting via a reduction gear disposed on the tip side equipped with a motor in the vicinity of the base end side pivot section of Jikuhari (Jikuhari pin) since the motor can be distributed as a mass on the vibration system of the spring between or springs, it is reduced load under spring, as well as reduce the vibration energy applied to the track and around, improves ride comfort, also exciting force to the motor It can be reduced.
