- the support structure in between is simplified, and the assembly workability of the cart is greatly improved.
- the abutting member 333 of the lateral beam 304 is not fixed in the vertical direction with respect to the long member 330, it becomes difficult to transmit a torsional force between the lateral beam 304 and the elongated member 330. Therefore, it is not necessary to increase the strength of each member or to reinforce the carriage as a countermeasure against twisting, and the weight reduction of the carriage can be promoted.
- the torsional force is difficult to be transmitted between the side beam 304 and the long member 330, it is possible to suppress occurrence of wheel load loss on some of the wheels 6.

- the side cover 404 can be manufactured without using welding.
- angular part of the outer surface and inner surface of the horizontal body 460 is chamfered and rounded.
- the horizontal beam 404 can be automatically manufactured by a cutting machine, and skill work such as welding is not required, so that manufacturing efficiency and manufacturing accuracy are improved.
- This configuration is combined with a configuration in which the horizontal beam 404 is not welded to the side member (the leaf spring 30 or the long member 330), so that the work for removing the accumulated distortion due to welding is greatly reduced, and the manufacturing efficiency is dramatically improved. Can be improved.
- FIG. 13 is a side view of a carriage 501 according to the eighth embodiment of the present invention.
- FIG. 14 is a side view of the leaf spring 530 in the carriage 501 shown in FIG.
- the cart 501 of the eighth embodiment uses a leaf spring 530 formed in a bow shape that protrudes downward as a whole in a side view.
- the leaf spring 530 has an arc shape in which a longitudinal center portion 530a protrudes downward, and both longitudinal end portions 530c are warped upward. Therefore, the lower surfaces of the longitudinal ends 530c of the leaf spring 530 are flat surfaces but are inclined with respect to the horizontal plane. That is, the lower surfaces of both longitudinal ends 530c are inclined so as to become higher toward the outside in the vehicle longitudinal direction.
- a support member 531 is attached to the upper end portion of the axle box 8, and both longitudinal end portions 530 c of the leaf spring 530 are placed on the upper surface of the support member 531 from above. Then, the upper surface of the support member 530 is inclined with respect to the horizontal plane so as to extend along the longitudinal ends 530c of the leaf spring 530.
- a contact member 533 having an arc-shaped lower surface 533a is provided at the lower part of both end portions 4a in the vehicle width direction of the horizontal beam 4, and the contact member 533 is formed on the longitudinal center portion 530a of the leaf spring 530 from above. It is placed and is in free contact. However, the contact member 533 and the leaf spring 530 are not provided with a fitting portion that fits in the vertical direction.
- An interposition sheet 570 (for example, a rubber sheet) that contacts the contact member 533 is provided on the upper surface of the longitudinal center 530a of the leaf spring 530.
- the leaf spring 530 has an upper layer 561, an intermediate layer 562, and a lower layer 563, and the volume of the intermediate layer 562 is larger than the entire volume of the upper layer 561 and the lower layer 563.

- the thickness is thinner than the wall thickness of the lower layer 563.
- the inclination angle ⁇ of the longitudinal ends 530c of the leaf spring 530 with respect to the horizontal plane is set to a value of 10 ° to 25 ° (for example, 15 °). .
- vibrations in the up / down, front / rear and left / right directions are transmitted from the wheels 6 to the bogie frame, and the vertical vibration component which is the dominant acceleration among the vibration components is transmitted and absorbed by the leaf spring 530.
- the upward force F transmitted from the support member 531 to the leaf spring 530 by vibration is applied to the longitudinal ends 530c of the leaf spring 530.
- the leaf spring 530 is not fixed to the contact member 533, and can rotate like a seesaw along the arcuate lower surface 533a of the contact member 533. Therefore, when vertical vibration is transmitted to the end 530c on one side in the longitudinal direction of the leaf spring 530, acceleration of the vertical vibration can be absorbed also by rotation about the longitudinal center portion 530a of the leaf spring 530.
- the end portion on the side having the larger inclination angle ⁇ becomes larger than the inclination angle ⁇ of the end portion 530c on the other side in the longitudinal direction due to vibration, the end portion on the side having the larger inclination angle ⁇ .
- the component force Fa of 530c is smaller than the component force Fa of the end portion 530c on the side where the inclination angle ⁇ is small. Therefore, a force is applied so that the inclination angles ⁇ on both sides in the longitudinal direction of the leaf spring 530 are the same (that is, so as to return to the original posture), and the leaf spring 530 has a self-correcting function for maintaining equilibrium. .
- the curvature of the leaf spring 530 increases.
- the direction center portion 530a falls relatively downward. This acts in the direction in which the contact member 533 supported by the longitudinal center portion 530a of the leaf spring 530 falls downward, so that an upward acceleration component transmitted from the support member 531 to the contact member 533 via the leaf spring 530.
- the longitudinal end portions 530 c of the leaf spring 530 are bent to absorb the upward acceleration transmitted from the support member 531 and to reduce the vibration transmission to the contact member 533. .
- the present invention is not limited to the above-described embodiment, and the configuration can be changed, added, or deleted without departing from the spirit of the present invention.

Abstract
Description
(第1実施形態)
図1は、本発明の第1実施形態に係る鉄道車両用台車1を表した斜視図である。図2は、図1に示す板バネ台車1の平面図である。図3は、図1に示す板バネ台車1の側面図である。図1乃至3に示すように、鉄道車両用台車1は、二次サスペンションとなる空気バネ2を介して車体11を支持するための台車枠3として車幅方向(以下、横方向ともいう)に延びる横ばり4を備えているが、横ばり4の横方向両端部から車両長手方向(以下、前後方向ともいう)に延びる側ばりを備えていない。横ばり4の前方及び後方には、横方向に沿って前後一対の車軸5が配置されており、車軸5の横方向両側には車輪6が固定されている。車軸5の横方向両端部には、車輪6よりも横方向外側にて車軸5を回転自在に支持する軸受7が設けられ、その軸受7は軸箱8に収容されている。横ばり4には、電動機9が取り付けられており、その電動機9の出力軸には、車軸5に動力を伝達する減速ギヤが収容されたギヤボックス10が接続されている。なお、横ばり4には、車輪6の回転を制動するためのブレーキ装置(図示せず)も設けられている。
図7は、本発明の第2実施形態に係る板バネ台車の図4相当の図面である。図7に示すように、第2実施形態の板バネ台車は、横ばり104の当接部材133の前後方向両端部分に弾性部材52(例えば、ゴム)を設けている。具体的には、当接部材133は、角パイプ12に固定された固定板32の下面に固定された剛性部材(例えば、金属や繊維強化樹脂等で構成された非弾性部材)からなる本体部51と、その本体部51の前後方向両側に隣接して配置された弾性部材52とを備えている。本体部51及び弾性部材52の下面は、側面視で滑らかに連続して下方に向けて凸となる略円弧形状の接触面133aを形成している。これにより、横ばり104に対する下方荷重の増加によって板バネ30が弾性変形して当接部材133の前後方向両端部分に接触しても、当該部分が弾性部材52からなるので、板バネ30への局所的な負荷を良好に緩和することができる。なお、他の構成は前述した第1実施形態と同様であるため説明を省略する。
図8は、本発明の第3実施形態に係る板バネ台車の図4相当の図面である。図8に示すように、第3実施形態の板バネ台車は、横ばり204の当接部材233の下面に板バネ30の上面と面接触する弾性部材152(例えば、ゴム)を設けている。具体的には、当接部材233は、角パイプ12に固定された固定板32の下面に固定された剛性部材(例えば、金属や繊維強化樹脂等で構成された非弾性部材)からなる本体部51と、その本体部51の下面及び前後方向両端を覆う弾性部材152とを備えている。本体部51の下面は、側面視で下方に向けて凸となる略円弧形状を呈し、弾性部材152の下面は、側面視で下方に向けて凸となる略円弧形状の接触面233aを形成している。
図9は、本発明の第4実施形態に係る板バネ台車の図6相当の図面である。図9に示すように、第3実施形態の板バネ台車は、板バネ130(側部材)の前後方向両端部130cにおいて繊維強化樹脂からなる下層部35の下面にゴム板61が固着されている。軸箱8の上端部に設けた支持部材131は、下から順に、ゴム板41及び金属板42が積層されてなる。即ち、支持部材131の上面が金属で形成されているが、板バネ130の前後方向両端部130cの下面がゴムで形成されているので、板バネ130の繊維強化樹脂からなる下層部35を良好に保護することができる。なお、他の構成は前述した第1実施形態と同様であるため説明を省略する。
図10は、本発明の第5実施形態に係る板バネ台車の図6相当の図面である。図10に示すように、第5実施形態の板バネ台車は、軸箱8の上端部に設けた支持部材231の上面が側面視で上方に向けて凸である略円弧状に形成されている。具体的には、支持部材231は、下から順に、ゴム板41、金属板42及びゴム板143が積層されてなり、その最上層のゴム板143の上面143aが側面視で略円弧形状に形成されている。即ち、側面視において、支持部材231の上面143aの曲率は、板バネ30の支持部材231と接触する部分(前後方向両端部30c)の下面の曲率よりも大きい。これにより、板バネ30の当接部材33(図4)との接触箇所から板バネ30の支持部材231との接触箇所までの最短距離は、横ばり4(図4)に対する下方荷重が増加して板バネ30が弾性変形するにつれて短くなる。そうすると、車体11への乗車率が増加するにつれて板バネ30のバネ定数が増加することとなる。よって、乗車率の変化に応じてバネ定数が変化して、乗車率が低いときも高いときも乗り心地の良い車両を実現することができる。なお、他の構成は前述した第1実施形態と同様であるため説明を省略する。
図11は、本発明の第6実施形態に係る台車301の図3相当の図面である。図11に示すように、第6実施形態の板バネ台車301は、板バネ30の代わりに、剛性部材(例えば、金属や繊維強化樹脂等で構成された非弾性部材)からなり前後方向に延びる長尺部材330(側部材)を用いている。長尺部材330は、例えば、筒形状を有している。長尺部材330は、横ばり304の横方向両端部304aを支持する前後方向中央部330aと、軸箱8に支持されて中央部330aよりも高い位置にある前後方向両端部330cと、中央部330aと両端部330cとを接続する傾斜部330bとを有している。即ち、長尺部材330は、中央部330aとその前後にある一対の傾斜部330bとで凹部を構成している。長尺部材330の両端部330cと軸箱8との間には、一次サスペンションとしてコイルバネ331が介装されている。長尺部材330の傾斜部330bの一部は、側面視で連結機構16と重なる位置に配置されている。具体的には、長尺部材330の傾斜部330bの一部は、一対の受け座21,22で挟まれた空間27(図1参照)を挿通している。
図12は、本発明の第7実施形態に係る台車の横ばり404の側方(左右方向)から見た断面図である。図12に示すように、第7実施形態の横ばり404は、金属を切削加工してなる横ばり本体460と、その横ばり本体460の加工面に形成された開口部460gを塞ぐ板状の蓋461とを備えている。横ばり本体460は、金属からなる横方向に長尺の六面体を一面側(本例では下面側)から切削加工して凹空間Sが形成されたものである。これにより、横ばり本体460は、上壁部460a、前壁部460b、後壁部460c、右壁部460dおよび左壁部460eの5面の外壁部を備えるとともに、凹空間Sを区切る内壁部460fを備える。そして、横ばり本体460の下面には、凹空間Sの開口部460gを塞ぐように蓋461が取り付けられている。この蓋461は、横ばり本体460よりも薄肉なプレートであり、固定具(例えば、ボルトやネジ等)により横ばり本体460に固定されている。つまり、横ばり404は、溶接を用いずに製作が可能である。なお、横ばり本体460の外面及び内面の角部は、面取り加工が施されて丸められている。
図13は、本発明の第8実施形態に係る台車501の側面図である。図14は、図13に示す台車501における板バネ530の側面図である。図13及び14に示すように、第8実施形態の台車501では、側面視において全体として下方に凸となる弓形状に形成された板バネ530が用いられている。板バネ530は、側面視において、その長手方向中央部530aが下方に向けて突出する円弧形状であり、その長手方向両端部530cが上方に向けて反っている。よって、板バネ530の長手方向両端部530cの下面は、平坦面ではあるが、水平面に対して傾斜している。即ち、長手方向両端部530cの下面は、車両長手方向の外側に向かうにつれて高くなるように傾斜している。
