Abstract
Description
このインホイールモータ駆動車輪において、前記モータから延在するモータ側給電線と車載電源から延在する車体側給電線とを、前記モータ側給電線に対し前記車体側給電線を相対回転可能に電気的に接続する電気接続機構を設ける。
前記電気接続機構を、前記ホイールのホイール凹部の空間外で、且つ、前記ナックルに配置した。
すなわち、ナックルは、車輪を転舵する際の転舵中心軸であるキングピン軸の軸線周りに転舵可能に設けられた部材である。したがって、ナックルに配置した電気接続機構は、キングピン軸に近接して配置されることになる。このため、電気接続機構に接続される車体側給電線は、車輪を大きく転舵させたとしてもキングピン軸の軸線周りを小さな回転半径に沿って振れ回るというように、転舵に伴う車体側給電線の振れ回りが低減される。
この結果、車輪を転舵したとき、転舵に伴う車体側給電線の振れ回りを低減することができる。
図1は、実施例1のモータ給電線配索構造が適用されたインホイールモータ駆動車輪の取付け部の断面を示す。以下、図1に基づき、インホイールモータ駆動車輪の全体構成を説明する。
図3は、実施例1のモータ給電線配索構造の回転電源端子取付け断面A-A相当におけるモータ電線と回転電源端子電線を示す。以下、図3に基づき、実施例1のインホイールモータ駆動車輪のモータ給電線配索作用を説明する。
この比較例の場合、右転舵角θRによる車輪転舵を行うと、転舵中立位置のバネ下給電線Cからモータ電源端子と共に回転半径R2に沿ってバネ下給電線がC’の位置まで大きく振れ回る。また、左転舵角θLによる車輪転舵を行うと、転舵中立位置のバネ下給電線Cからモータ電源端子と共に回転半径R2に沿ってバネ下給電線がC”の位置まで大きく振れ回る。このとき、バネ下給電線の最小曲げ半径と車体側を固定された電源端子に制約されることで、右転舵でのバネ下給電線C’は、図3に示すように、車両前方側に大きく膨らむ円弧形状になる。また、左転舵でのバネ下給電線がC”は、図3に示すように、ショッアブシャフト9に接触干渉して曲がり変形する。
すなわち、右転舵角θRと左転舵角θLに対しナックル6に配置された回転電源端子12が回転するものの、回転電源端子12はモータ電源端子5aより仮想キングピン軸7に近い。このため、回転電源端子12の回転半径R1は、モータ電源端子の回転半径R2に比べて小さくなる。したがって、右転舵時には、転舵中立位置の可動給電線13bから回転電源端子12と共に回転半径R1に沿って可動給電線13b’の位置までの小さな振れ回りに抑えられる。また、左転舵時には、可動給電線13bから回転電源端子12と共に回転半径R1に沿って可動給電線13b”の位置までの小さな振れ回りに抑えられる。
この結果、タイヤ1を転舵したとき、転舵に伴う可動給電線13bの振れ回りを低減することができる。
例えば、回転電源端子をナックルに配置するとき、キングピン軸の延長方向であればナックル上方に配置することも可能である。しかし、ナックル上方に回転電源端子を配置した場合、回転電源端子との干渉を避ける必要がある分、ホイールハウスの高さが高くなってしまう。このため、車高またはフード高が上がってしまうことになり、車両としての魅力が低減してしまう。
また、モータ上部のホイール凹部の空間内に配置することも可能である。しかし、ホイール内に回転電源端子を設けた場合には、回転電源端子の設置スペースをホイール内に確保する必要がある分、ホイール径を大きくせざるを得ず、車輪が大型化してしまう。このため、上記回転電源端子をナックルの上方に配置した場合と同様に、ホイールハウスの高さが高くなってしまうし、車高またはフード高が上がってしまうことになり、車両としての魅力が低減してしまう。
これに対し、回転電源端子12を、ホイール2のホイール凹部2aの空間外のナックル6に配置することで、ホイールハウスの高さを低くでき、車高またはフード高が上がることなく、デザイン自由度が向上し、車両としての魅力が高くなる。
このように、ナックル6のナックル幅を、モータ軸方向視でモータ直径よりも小さく設定したことで、回転電源端子12をより仮想キングピン軸7に近づけることができる。そして、回転電源端子12が左右方向の転舵に伴い回転すると、可動給電線13bから引っ張られる力により回転部12bが回転し、可動給電線13bの回転部12bとの接続点が最短に向く。すなわち、各転舵位置での可動給電線13b,13b’,13b”が、図3に示すように、車載電源側と回転部12bを結ぶ直線状給電線になる。
したがって、ナックル幅をモータ直径よりも大きく設定した場合より回転電源端子12を仮想キングピン軸7に近づけることができると共に、可動給電線13bの自由全長の短縮が図れることで、可動給電線13bの振れ回りをより小さく抑えることができる。また、振れ回り空間が低減化されることで、周辺部品の設計自由度が増す。併せて、回転変位自由度を有する回転電源端子12の回転部12bの動きにより、可動給電線13b自身の振れ・捻り・変形なども低減できる。また、もともとデッドスペースだったナックル6の周囲空間を活用することができるため、回転電源端子12を配置する為の余分な空間を設けることなく、可動給電線13bの振れ回りを防止することができる。
例えば、2相のホイールインモータ5の場合、2個の回転電源端子12,12に対して2本の可動給電線13b,13bが接続されることになる。このとき、2本の可動給電線13b,13bに対し、転舵に伴う振れ回り低減効果に差を持たせることなく、振れ回りを共に小さく抑えることができる。
実施例1のインホイールモータ駆動車輪のモータ給電線配索構造にあっては、下記に列挙する効果を得ることができる。
前記ナックル6に回転可能に支持された車軸に接続されたホイール2と、
前記車軸に駆動力を与えるモータ(インホイールモータ5)と、
を備えたインホイールモータ駆動車輪において、

前記電気接続機構(回転電源端子12)を、前記ホイール2のホイール凹部2aの空間外で、且つ、前記ナックル6に配置した(図1)。
このため、車輪(タイヤ1)を転舵したとき、転舵に伴う車体側給電線(可動給電線13b)の振れ回りを低減することができる。さらに、ホイール2のホイール凹部2aの空間外のナックル6に電気接続機構(回転電源端子12)を配置したため、ホイールハウスの高さを低く抑えることができる。
前記電気接続機構(回転電源端子12)は、前記モータ側給電線(固定給電線13a)が接続される固定部12aと、前記車体側給電線(可動給電線13b)が接続される回転部12bと、を有し、前記固定部12aを車両上下方向の下側に配置し、前記回転部12bを車両上下方向の上側に配置した(図1)。
このため、(1)の効果に加え、電気接続機構(回転電源端子12)をより仮想キングピン軸7に近づけることができると共に、車体側給電線(可動給電線13b)の自由全長の短縮が図れることで、車体側給電線(可動給電線13b)の振れ回りをより小さく抑えることができる。
このため、(1)又は(2)の効果に加え、複数個の電気接続機構(回転電源端子12)に接続される複数本の車体側給電線(可動給電線13b)に対し、転舵に伴う振れ回り低減効果に差を持たせることなく、振れ回りを共に小さく抑えることができる。

実施例4のインホイールモータ駆動車輪のモータ給電線配索構造にあっては、実施例1の(1)~(3)の効果に加え、下記の効果を得ることができる。
このため、複数個の電気接続機構(回転電源端子12(1),12(2),12(3))を仮想キングピン軸7に近づけてナックル6の周りに配置しても、複数本の車体側給電線(可動給電線13b(1),13b(2),13b(3))同士の干渉を防止することができる。
なお、他の構成及び作用については、実施例1と同様であるので、説明を省略する。
実施例5のインホイールモータ駆動車輪のモータ給電線配索構造にあっては、実施例1の(1)~(3)の効果に加え、下記の効果を得ることができる。
このため、ナックル6の近傍に他の部材が配置された場合でも、ナックル6の仮想キングピン軸7に近接する位置への回転電源端子12の配置自由度を確保することができると共に、複数本の可動電源線13bによる干渉空間を減少させることができる。
なお、他の構成及び作用については、実施例1と同様であるので、説明を省略する。
実施例6のインホイールモータ駆動車輪のモータ給電線配索構造にあっては、実施例1の(1)~(3)の効果、実施例4の(4)の効果、実施例5の(5)の効果に加え、下記の効果を得ることができる。
このため、モータ(インホイールモータ5)の支持強度を補強することができると共に、部品点数の削減及びコンパクト化を図ることができる。さらに、固定給電線一体ブラケット14,15は、強化ゴムや強化プラスチックなどのように金属と異なるバネ定数を持つ構成なので、モータ自身の振動低減が図られ、モータケースの変形を抑えることもできる。
なお、他の構成及び作用については、実施例1と同様であるので、説明を省略する。
実施例7のインホイールモータ駆動車輪のモータ給電線配索構造にあっては、実施例1の(1)~(3)の効果、実施例4の(4)の効果、実施例5の(5)の効果、実施例6の(6)の効果に加え、下記の効果を得ることができる。

このため、部品点数削減と径方向の大きさを小型化しながらも、回転軸部材(回転接触部12e及び回転ネジ部12d)が回転しながら電気を常に安定して通電することができる。
なお、他の構成及び作用については、実施例1と同様であるので、説明を省略する。
実施例8のインホイールモータ駆動車輪のモータ給電線配索構造にあっては、実施例7の(7)の効果に加え、下記の効果を得ることができる。
