【0015】図1の断面図に示すように、この誘導式給電・集電装置は、車両の二次コイル5が複数のコイルa [0015] As shown in the sectional view of FIG. 1, the inductive power supply, current collector, the secondary coil 5 of the vehicle is more coils a
〜fからなっており、その各コイルa〜fは同一のコア4に捲き付けられている。 Has become a ~f, the coils a~f is attached plated on the same core 4. このコア4は、C型のコア4 The core 4 is, C-type core 4
を複数連結したような形状をしており、少なくとも一次インダクタ3のコア1と同じか、それ以上の幅を有している。 The shaped like a plurality linked, either the same as the core 1 at least the primary inductor 3, and a more wide. そして、そのそれぞれのC型の「I」形となった棒状部分にコイルa〜fが捲き付けられており、コイルa〜fを流れる電流の向きはコア4の上側と下側とで逆向きとなる。 Then, opposite in its bar-like portion is "I" shape of the respective C-type a coil a~f is attached Maki, the direction of the current flowing through the coil a~f the upper and lower sides of the core 4 to become. このようにコイルa〜fが取付けられたコア4は、車体の底部にC型の折曲側を一次インダクタ3 The core 4 coil a~f is mounted to the vehicle body bottom C-shaped bent side of the primary inductor 3 of the

fは走行路に対して横方向に配列される。 f is arranged transversely to the travel path.

【0016】この実施形態は、以上のように構成されており、図1に示すように、走行中の車体が横ずれを起こさない場合は、一次インダクタ3の発生する磁束Bは二次インダクタ6のコア4によって集束され、コア4の両端を通って全てのコイルa〜fと鎖交する。 [0016] This embodiment is constructed as described above, as shown in FIG. 1, if the vehicle body during traveling does not cause lateral displacement, the magnetic flux B generated in the primary inductor 3 of the secondary inductor 6 is focused by the core 4, all the coils a~f interlinked through both ends of the core 4.

【0017】いま、走行中の車体が横ずれを起こし、車体の半分程度がずれた場合には、二次インダクタ6のコア4をC型のコア4を連結したような構造としたことにより、ちょうど、一次インダクタ3の極と対向するもっとも近いC型の折曲部が図2に示すように、一次インダクタコイル2の発生した磁束を集束する。 [0017] Now, the vehicle body during traveling undergoes a lateral displacement, when about the body half is displaced, by the core 4 of the secondary inductor 6 has a structure as the concatenation of the C-shaped core 4, just , bent portions of the nearest C type poles facing the primary inductor 3, as shown in FIG. 2, for focusing the magnetic flux generated in the primary inductor coil 2. このときコア4内を通る磁束は二次コイル5のaとbとcと鎖交するため、このコイルa、b、cの出力を合成すれば集電が可能となる。 Since magnetic flux passing through the core 4 at this time it is interlinked a and b and c and chains of the secondary coil 5, the coil a, b, current collecting is possible by combining the outputs of the c.

【0018】さらに、車体が半分以上ずれた場合でも図3に示すように、コア4によって集束された磁束はコイルaと鎖交することができるので、集電が可能であり、 Furthermore, as shown in FIG. 3, even if the vehicle body is shifted over half, the magnetic flux that is focused by the core 4 can coils a interlinked, are possible collector,
車体の横ずれに対する集電電力と集電効率の低下を少なくすることができる。 It is possible to reduce the deterioration of the current collecting power and current collection efficiency with respect to the vehicle body of the lateral shift.

二次インダクタンス6のコイルa〜fを同じコアに取付けたことにより、一次インダクタ3の磁束と鎖交するコイルa、bの自己誘導作用によって発生する逆方向の磁束B′と一次インダクタ3の磁束と鎖交しないコイルc By attaching the coil a~f secondary inductance 6 in the same core, the primary inductor 3 of the magnetic flux interlinked with the coil a, the magnetic flux in the opposite direction of the magnetic flux B 'and the primary inductor 3 generated by self-induction action of b coil c is not interlinked with the chain
〜fとの相互誘導作用によって前記コイルc〜fが逆起電力を発生し、集電電力の低下を起こすが、この場合もこの逆起電力を起こすコイルc〜fをセレクタスイッチ7により、切り離すことによって、集電効率の低下を防止することができる。 It said coil c~f generates a counter electromotive force by the mutual induction action between ~f, but causes a decrease of the collector power, even in this case the selector switch 7 to the coil c~f causing this counter electromotive force, disconnected by, it is possible to prevent a decrease in collection efficiency.

【効果】以上のように構成される第1の発明では、車両の二次インダクタを走行路に対して横方向に配列された複数のコイルを有するものとしたことにより、横ずれに対して集電電力ならびに集電効率の低下の少ない誘電給電を可能とすることができる。 [Effect] In the first invention configured as described above, by having assumed to have a plurality of coils arranged laterally secondary inductor of the vehicle relative to the roadway, the collector against lateral displacement power as well as to enable small dielectric feeder of decrease in collection efficiency.

【0030】第2の発明では、二次コイルの複数のコイルを一次コイルとの磁束の鎖交数に応じて切り離す集電切り替えスイッチを備えたにより、磁束が鎖交しないことによって集電に寄与しないコイルや逆方向の磁束が鎖交し集電を妨げるコイルを集電出力から切り離してロスの少ない集電を可能とし、集電電力及び集電効率の低下を防止することができる。 [0030] In the second invention, the contribution to the current collector by more with a current collecting selector switch disconnecting according a plurality of coils of the secondary coil to the flux of the chain interlinkage with the primary coil, magnetic flux is not interlinked with a coil flux of the coil and reverse prevents strand interlinked collector not to allow the small current collecting Los separately from the collector output, it is possible to prevent deterioration of the current collecting power and current collecting efficiency.

【0031】第3の発明では、上記車両の横ずれを検出するセンサを備えて、そのセンサ出力によって上記二次コイルの集電電力がもっとも多くなるように上記集電切り替えスイッチを自動的に切り替えることができるので、横ずれに対する集電切換えスイッチの切り替え応答を早くして集電電力及び集電効率の低下を防止することができる。 [0031] In the third invention, provided with a sensor for detecting a lateral displacement of the vehicle, automatically switching the collector changeover switch to the collector power of the secondary coil is most by the sensor output since it is, it is possible to prevent deterioration of the current collecting power and current collecting efficiency by quickly switching response of the current collector changeover switch for lateral displacement.
