しかしながら、特許文献１に開示された技術では、電力線の動きを規制する手段として固定側ガイドや中間ローラを設ける必要があり、構造が複雑になるという問題がある。また、特許文献１に開示された技術では、電力線が中間ローラに巻き付くが、この部分において電力線に負荷が大きくなり、電力線の耐久性低下を招くおそれもある。   However, in the technique disclosed in Patent Document 1, it is necessary to provide a fixed-side guide and an intermediate roller as means for regulating the movement of the power line, and there is a problem that the structure becomes complicated. Further, in the technique disclosed in Patent Document 1, the power line is wound around the intermediate roller. However, in this portion, the load on the power line is increased, and the durability of the power line may be reduced.

以下、この発明につき図面を参照しつつ詳細に説明する。なお、この発明を実施するための最良の形態（以下実施形態という）によりこの発明が限定されるものではない。また、下記実施形態における構成要素には、当業者が容易に想定できるもの、あるいは実質的に同一のもの、いわゆる均等の範囲のものが含まれる。本発明は、いわゆるインホイールモータのように、懸架装置のリンクに電動機が取り付けられる車両であれば適用可能であり、電動機のみを駆動源とする車両である必要はない。   Hereinafter, the present invention will be described in detail with reference to the drawings. The present invention is not limited by the best mode for carrying out the invention (hereinafter referred to as an embodiment). In addition, constituent elements in the following embodiments include those that can be easily assumed by those skilled in the art, or substantially the same, so-called equivalent ranges. The present invention is applicable to any vehicle in which an electric motor is attached to a link of a suspension device, such as a so-called in-wheel motor, and does not need to be a vehicle using only the electric motor as a drive source.

この実施形態は、いわゆるインホイールモータのように、車両の懸架装置を構成するリンク（アーム）に電動機を取り付ける車両において、電動機へ電源を供給したり電動機の制御に用いる情報を車内の制御装置へ伝達したりするための電線を前記リンクに沿わせて配置するとともに、電動機と前記電線との接続部から前記電線が引き出される方向は、懸架装置が動作する際に電動機が移動する方向に対して交差（好ましくは交差角度が９０度、概ね６０度以上）するように構成する点に特徴がある。   In this embodiment, like a so-called in-wheel motor, in a vehicle in which an electric motor is attached to a link (arm) constituting a suspension device of the vehicle, information used to supply electric power to the electric motor or to control the electric motor is transmitted to the in-vehicle control device. An electric wire for transmission is arranged along the link, and the direction in which the electric wire is drawn out from the connection portion between the electric motor and the electric wire is relative to the direction in which the electric motor moves when the suspension device operates. It is characterized in that it is configured to intersect (preferably the intersection angle is 90 degrees, approximately 60 degrees or more).

図１は、この実施形態に係る電線の配線構造を適用した車両の構成例を示す概念図である。図１中の「ＩＮ」は車両１の内側を示し、「ＯＵＴ」は車両１の外側を示す。車両１は、電動機を動力発生手段とする走行装置１００を備える。走行装置１００は、駆動輪のホイール内に電動機が配置されるとともに、電動機は懸架装置のリンクに取り付けられる、いわゆるインホイールモータ形式の走行装置１００を備えている。   FIG. 1 is a conceptual diagram showing a configuration example of a vehicle to which the wire wiring structure according to this embodiment is applied. “IN” in FIG. 1 indicates the inside of the vehicle 1, and “OUT” indicates the outside of the vehicle 1. The vehicle 1 includes a traveling device 100 that uses an electric motor as power generation means. The traveling device 100 includes a traveling device 100 of a so-called in-wheel motor type in which an electric motor is disposed in a wheel of a drive wheel, and the electric motor is attached to a link of a suspension device.

車両１は、矢印Ｘ方向に前進し、車両１の前進方向を基準として左右を区別する。すなわち、「左」とは、車両１の前進する方向に向かって左側をいい、「右」とは、車両１の前進する方向に向かって右側をいう。また、車両１の前進方向側を車両１の前あるいは前方とし、車両１の後進方向を車両１の後あるいは後方とする。   The vehicle 1 moves forward in the direction of the arrow X, and distinguishes left and right on the basis of the forward direction of the vehicle 1. That is, “left” refers to the left side in the direction in which the vehicle 1 moves forward, and “right” refers to the right side in the direction in which the vehicle 1 moves forward. Further, the forward direction side of the vehicle 1 is the front or front of the vehicle 1, and the backward direction of the vehicle 1 is the rear or rear of the vehicle 1.

この実施形態において、走行装置１００が備える動力発生手段は、車両１の左側前輪２ＦＬを駆動する左側前輪用電動機１０ＦＬ、右側前輪２ＦＲを駆動する右側前輪用電動機１０ＦＲ、左側後輪２ＲＬを駆動する左側後輪用電動機１０ＲＬ、右側後輪２ＲＲを駆動する右側後輪用電動機１０ＲＲである。このように、車両１は、４輪すべてが駆動輪となる。なお、車両１は、４輪すべてが駆動輪となる必要はなく、少なくとも１輪が駆動輪となればよい。車両１の各輪の駆動力は、ＥＣＵ（Electronic Control Unit）５０によって制御される。そして、必要に応じて各輪の駆動力の配分比がＥＣＵ５０によって変更される。この実施形態においては、アクセル開度センサ４２によって検出されるアクセル５の開度により走行装置１００の総駆動力Ｆが制御される。   In this embodiment, the power generation means included in the traveling device 100 includes a left front wheel motor 10FL that drives the left front wheel 2FL of the vehicle 1, a right front wheel motor 10FR that drives the right front wheel 2FR, and a left side that drives the left rear wheel 2RL. They are a rear wheel motor 10RL and a right rear wheel motor 10RR that drives the right rear wheel 2RR. Thus, the vehicle 1 has all four wheels as drive wheels. The vehicle 1 does not need to be all four wheels, and at least one wheel may be a driving wheel. The driving force of each wheel of the vehicle 1 is controlled by an ECU (Electronic Control Unit) 50. And the distribution ratio of the driving force of each wheel is changed by ECU50 as needed. In this embodiment, the total driving force F of the traveling device 100 is controlled by the opening of the accelerator 5 detected by the accelerator opening sensor 42.

なお、電動機と車輪との間に減速機構を設け、それぞれの電動機の回転数を減速して各車輪へ伝達してもよい。一般に、電動機は小型化するとトルクが低下するが、減速機構を設けることによって電動機のトルクを増加させることができる。その結果、左側前輪用電動機１０ＦＬ、右側前輪用電動機１０ＦＲ、左側後輪用電動機１０ＲＬ及び右側後輪用電動機１０ＲＲを小型化することができる。   A speed reduction mechanism may be provided between the electric motor and the wheel, and the rotational speed of each electric motor may be reduced and transmitted to each wheel. In general, when the electric motor is downsized, the torque decreases, but the torque of the electric motor can be increased by providing a speed reduction mechanism. As a result, the left front wheel motor 10FL, the right front wheel motor 10FR, the left rear wheel motor 10RL, and the right rear wheel motor 10RR can be reduced in size.

左側前輪用電動機１０ＦＬ、右側前輪用電動機１０ＦＲ、左側後輪用電動機１０ＲＬ及び右側後輪用電動機１０ＲＲは、それぞれ、左側前輪レゾルバ４０ＦＬ、右側前輪レゾルバ４０ＦＲ、左側後輪レゾルバ４０ＲＬ及び右側後輪レゾルバ４０ＲＲによって回転角度や回転速度が検出される。各レゾルバの出力は、ＥＣＵ５０に取り込まれて、左側前輪用電動機１０ＦＬ、右側前輪用電動機１０ＦＲ、左側後輪用電動機１０ＲＬ及び右側後輪用電動機１０ＲＲの制御に用いられる。   The left front wheel motor 10FL, the right front wheel motor 10FR, the left rear wheel motor 10RL, and the right rear wheel motor 10RR are respectively a left front wheel resolver 40FL, a right front wheel resolver 40FR, a left rear wheel resolver 40RL, and a right rear wheel resolver 40RR. Thus, the rotation angle and the rotation speed are detected. The output of each resolver is taken into the ECU 50 and used to control the left front wheel motor 10FL, the right front wheel motor 10FR, the left rear wheel motor 10RL, and the right rear wheel motor 10RR.

左側前輪用電動機１０ＦＬ、右側前輪用電動機１０ＦＲ、左側後輪用電動機１０ＲＬ及び右側後輪用電動機１０ＲＲは、インバータ３に接続されている。インバータ３には、例えばニッケル−水素電池や鉛蓄電池、あるいは燃料電池４Ｆ等の車載電源４が接続されており、必要に応じてインバータ３を介して各電動機へ供給される。この実施形態に係る車両１が燃料電池車両である場合、車両１は少なくとも燃料電池４Ｆを備える。また、この実施形態に係る車両１が電気自動車（燃料電池を用いない方式）である場合、車両１は車載電源４のみを備える。各電動機が発生する出力は、ＥＣＵ５０からの指令によってインバータ３を制御することで制御される。なお、この実施形態においては、１台のインバータで１台の電動機を制御する。インバータ３には、４台電動機を制御するため、それぞれの電動機に対して１台ずつ、計４台のインバータが内蔵されている。   The left front wheel motor 10FL, the right front wheel motor 10FR, the left rear wheel motor 10RL, and the right rear wheel motor 10RR are connected to the inverter 3. For example, an in-vehicle power source 4 such as a nickel-hydrogen battery, a lead storage battery, or a fuel cell 4F is connected to the inverter 3, and is supplied to each electric motor via the inverter 3 as necessary. When the vehicle 1 according to this embodiment is a fuel cell vehicle, the vehicle 1 includes at least a fuel cell 4F. Further, when the vehicle 1 according to this embodiment is an electric vehicle (a system that does not use a fuel cell), the vehicle 1 includes only the in-vehicle power supply 4. The output generated by each electric motor is controlled by controlling the inverter 3 according to a command from the ECU 50. In this embodiment, one motor is controlled by one inverter. In order to control four motors, the inverter 3 has a total of four inverters, one for each motor.

左側前輪用電動機１０ＦＬ、右側前輪用電動機１０ＦＲ、左側後輪用電動機１０ＲＬ及び右側後輪用電動機１０ＲＲが走行装置１００の駆動源として用いられる場合、車載電源４の電力がインバータ３を介して供給される。また、例えば車両１の減速時には、左側前輪用電動機１０ＦＬ、右側前輪用電動機１０ＦＲ、左側後輪用電動機１０ＲＬ及び右側後輪用電動機１０ＲＲが発電機として機能して電池に蓄える回生発電を行い、これによって回収したエネルギをニッケル−水素電池や鉛蓄電池等の車載電源４に蓄える。これは、ブレーキ信号やアクセルオフ等の信号に基づいて、ＥＣＵ５０がインバータ３を制御することにより実現される。   When the left front wheel motor 10FL, the right front wheel motor 10FR, the left rear wheel motor 10RL, and the right rear wheel motor 10RR are used as the driving source of the traveling device 100, the power of the in-vehicle power supply 4 is supplied via the inverter 3. The For example, when the vehicle 1 is decelerated, the left front wheel motor 10FL, the right front wheel motor 10FR, the left rear wheel motor 10RL, and the right rear wheel motor 10RR function as a generator to perform regenerative power generation stored in the battery. Is stored in an in-vehicle power source 4 such as a nickel-hydrogen battery or a lead storage battery. This is realized by the ECU 50 controlling the inverter 3 based on a brake signal, an accelerator-off signal, or the like.

次に、この実施形態に係る電線の配線構造を説明する。次の説明においては、適宜図１を参照されたい。なお、車両１の走行装置１００が備える電動機は、左側前輪用電動機１０ＦＬ、右側前輪用電動機１０ＦＲ、左側後輪用電動機１０ＲＬ及び右側後輪用電動機１０ＲＲであるが、説明の便宜上、以下においてはそれぞれを区別せず、単に電動機１０という。そして、以下における構成は、車両１の走行装置１００が備える各電動機に対して共通の構成である。   Next, the wiring structure of the electric wire according to this embodiment will be described. In the following description, please refer to FIG. 1 as appropriate. The electric motors included in the traveling device 100 of the vehicle 1 are the left front wheel motor 10FL, the right front wheel motor 10FR, the left rear wheel motor 10RL, and the right rear wheel motor 10RR. Are simply referred to as the electric motor 10. The following configuration is a common configuration for each electric motor included in the traveling device 100 of the vehicle 1.

図２は、この実施形態に係る電線の配線構造を説明する斜視図である。図３は、この実施形態に係る電線の配線構造を説明する正面図である。図４は、この実施形態に係る電線の配線構造を説明する側面図である。図５は、この実施形態に係る電線の配線構造を説明する平面図である。次においては、いわゆるダブルウィッシュボーン形式の懸架装置に電動機１０を取り付けて、インホイールモータの構成とした例を説明するが、懸架装置の形式はこれに限られるものでない。例えば、いわゆるストラット形式やトーションビーム形式の懸架装置であってもよい。また、次においては、操舵輪（前輪）の懸架装置を例とする。ここで、図２〜図４中の矢印ｇ方向は、重力の作用方向（鉛直方向）を示している。重力の作用方向側が下、あるいは下側であり、重力の作用方向とは反対側が、上あるいは上側となる（以下同様）。   FIG. 2 is a perspective view for explaining the wiring structure of the electric wire according to this embodiment. FIG. 3 is a front view illustrating the wiring structure of the electric wire according to this embodiment. FIG. 4 is a side view for explaining the wiring structure of the electric wire according to this embodiment. FIG. 5 is a plan view for explaining the wiring structure of the electric wire according to this embodiment. In the following, an example will be described in which the electric motor 10 is attached to a so-called double wishbone type suspension device to form an in-wheel motor, but the type of suspension device is not limited to this. For example, a suspension device of a so-called strut type or torsion beam type may be used. In the following, a suspension device for a steered wheel (front wheel) is taken as an example. Here, the arrow g direction in FIGS. 2 to 4 indicates the action direction (vertical direction) of gravity. The gravity direction is the lower side or the lower side, and the side opposite to the gravity direction is the upper side or the upper side (the same applies hereinafter).

図２、図３に示すように、電動機１０は、懸架装置のリンクであるアッパーアーム２０Ｕとロワーアーム２０Ｌとによって支持される。より詳細には、電動機１０は、アッパーアーム２０Ｕのボールジョイント２２Ｕとロワーアーム２０Ｌのボールジョイント２２Ｌとによって上下方向（図２中の矢印Ｙ方向）に移動可能、かつキングピン軸Ｚｐ周りに回転可能に支持される。これによって、タイヤ２Ｔを路面に追従させるとともに、車両１の操舵輪として機能する。なお、ダブルウィッシュボーン形式の懸架装置において、キングピン軸Ｚｐは、アッパーアーム２０Ｕのボールジョイント２２Ｕとロワーアーム２０Ｌのボールジョイント２２Ｌとを結ぶ軸である。   As shown in FIGS. 2 and 3, the electric motor 10 is supported by an upper arm 20U and a lower arm 20L that are links of the suspension device. More specifically, the electric motor 10 is supported by a ball joint 22U of the upper arm 20U and a ball joint 22L of the lower arm 20L so as to be movable in the vertical direction (direction of arrow Y in FIG. 2) and rotatable about the kingpin axis Zp. Is done. Thus, the tire 2T follows the road surface and functions as a steering wheel of the vehicle 1. In the double wishbone type suspension device, the kingpin axis Zp is an axis connecting the ball joint 22U of the upper arm 20U and the ball joint 22L of the lower arm 20L.

電動機１０が発生する動力は、出力軸１０Ｓから取り出される。図３に示すように、出力軸１０Ｓには、ボルト９を介してホイール２Ｗが取り付けられる。ホイール２Ｗにはタイヤ２Ｔが取り付けられており、電動機１０の出力軸１０Ｓが回転すると、ホイール２Ｗ及びタイヤ２Ｔは電動機１０の回転軸（電動機回転軸）Ｚｒを中心として回転する。これによって、電動機１０の発生する動力は、ホイール２Ｗ及びタイヤ２Ｔを介して路面に伝達され、車両１を走行させる。なお、出力軸１０Ｓには、ディスクブレーキを構成するディスクロータ８が取り付けられている。   The power generated by the electric motor 10 is taken out from the output shaft 10S. As shown in FIG. 3, a wheel 2 </ b> W is attached to the output shaft 10 </ b> S via a bolt 9. A tire 2T is attached to the wheel 2W, and when the output shaft 10S of the electric motor 10 rotates, the wheel 2W and the tire 2T rotate about a rotation axis (electric motor rotation axis) Zr of the electric motor 10. As a result, the power generated by the electric motor 10 is transmitted to the road surface via the wheel 2W and the tire 2T, and the vehicle 1 is caused to travel. A disk rotor 8 constituting a disk brake is attached to the output shaft 10S.

電動機１０には、インバータ３（図１参照）から駆動用の電力を供給する電線（以下給電ケーブル）１２が接続される。電動機１０は、誘導電動機であり、３相の交流がインバータ３から供給されるので、３本の給電ケーブル１２が電動機１０に接続される。電動機１０には、給電ケーブル１２を接続する端子部（電線の接続部）１１が設けられており、ここに３本の給電ケーブル１２及び信号用電線（図示せず）の計４本が接続される。給電ケーブル１２は、車両１を走行させるための電気エネルギを電動機１０に供給するため、容量の大きい、すなわち太い電線が用いられる。このため、給電ケーブル１２は柔軟性に欠け、曲げやねじりが繰り返されると、耐久性が低下するおそれがある。なお、信号用電線も、給電ケーブル１２と同様に、曲げやねじりが繰り返されると、耐久性が低下するおそれがある。特に、インホイールモータ形式のように、タイヤ２Ｔとともに電動機１０が上下に移動したり、あるいはキングピン軸を中心に操舵されたりする場合、耐久性低下のおそれは高くなる。   The electric motor 10 is connected to an electric wire (hereinafter referred to as a power supply cable) 12 that supplies driving power from the inverter 3 (see FIG. 1). The electric motor 10 is an induction motor, and since three-phase alternating current is supplied from the inverter 3, the three power supply cables 12 are connected to the electric motor 10. The electric motor 10 is provided with a terminal portion (electric wire connecting portion) 11 for connecting a power feeding cable 12 to which a total of four power feeding cables 12 and signal wires (not shown) are connected. The The power feeding cable 12 uses a thick electric wire, that is, a thick electric wire in order to supply the electric energy for running the vehicle 1 to the electric motor 10. For this reason, the power feeding cable 12 lacks flexibility, and durability may be lowered when bending and twisting are repeated. Note that, as with the power supply cable 12, if the signal wire is repeatedly bent and twisted, the durability may decrease. In particular, when the electric motor 10 moves up and down together with the tire 2T or is steered around the kingpin shaft as in the in-wheel motor type, the risk of a decrease in durability increases.

この実施形態に係る電線の配線構造では、電線である給電ケーブル１２を、懸架装置のリンク（この実施形態ではアッパーアーム２０Ｕ）に沿わせて、電線固定手段であるケーブルクランプ１３でアッパーアーム２０Ｕに固定する（図２、図３、図５参照）。また、車両１が水平面ＧＬに設置された状態において、電線の接続部である端子部１１から電線である給電ケーブル１２が引き出される位置（電線引き出し位置）１２Ｃ（図４参照）の水平面ＧＬからの距離ｈｃは、給電ケーブル１２が配置される前記アッパーアーム２０Ｕの水平面ＧＬからの距離ｈａと同等としてある。   In the wiring structure of the electric wire according to this embodiment, the power feeding cable 12 that is an electric wire is placed along the link of the suspension device (in this embodiment, the upper arm 20U), and is connected to the upper arm 20U by the cable clamp 13 that is an electric wire fixing means. Fix (see FIGS. 2, 3 and 5). Further, in a state where the vehicle 1 is installed on the horizontal plane GL, the position (electric wire drawing position) 12C (see FIG. 4) from the horizontal plane GL where the feeding cable 12 that is the electric wire is drawn out from the terminal portion 11 that is the connecting portion of the electric wire. The distance hc is equivalent to the distance ha from the horizontal plane GL of the upper arm 20U where the power supply cable 12 is disposed.

ここで、ｈｃとｈａが同等とは、両者が等しい場合の他、リンクであるアッパーアーム２０Ｕと給電ケーブル１２との距離の絶対値｜ｈｃ−ｈａ｜が、給電ケーブル１２の直径の５倍以内、又は５０ｍｍ以内である場合も含む。また、電線引き出し位置１２Ｃの水平面ＧＬからの距離ｈｃは、給電ケーブル１２の中心を基準として規定する。また、アッパーアーム２０Ｕの水平面ＧＬからの距離ｈａは、電動機１０と電線（給電ケーブル１２）を沿わせて配置する懸架装置のリンク（この実施形態ではアッパーアーム２０Ｕ）との結合部中心（この実施形態では、ボールジョイント２２Ｕの中心）を基準として規定する。   Here, hc and ha are equal to each other, in addition to the case where both are equal, the absolute value | hc−ha | of the distance between the upper arm 20U, which is a link, and the feeding cable 12 is within five times the diameter of the feeding cable 12 Or within 50 mm. Further, the distance hc from the horizontal plane GL of the wire drawing position 12C is defined with the center of the power feeding cable 12 as a reference. Further, the distance ha from the horizontal plane GL of the upper arm 20U is the center of the connecting portion between the motor 10 and the link of the suspension device (upper arm 20U in this embodiment) arranged along the electric wire (feed cable 12) (this implementation). In the form, it is defined with reference to the center of the ball joint 22U.

また、図４に示すように、この実施形態に係る電線の配線構造では、電線の接続部である端子部１１から電線である給電ケーブル１２が引き出される方向（矢印Ｃ方向）は、キングピン軸Ｚｐと交差（この実施形態では略直交）するようになっている。このような構成によって、この実施形態では、懸架装置の動作（上下動）にともなう電動機１０の動作（上下動）に起因する給電ケーブル１２の曲げやねじれを低減する。   As shown in FIG. 4, in the wiring structure of the electric wire according to this embodiment, the direction (arrow C direction) in which the power feeding cable 12 as the electric wire is drawn out from the terminal portion 11 as the electric wire connecting portion is the kingpin axis Zp. And intersect (substantially orthogonal in this embodiment). With this configuration, in this embodiment, bending and twisting of the power feeding cable 12 due to the operation (vertical movement) of the electric motor 10 accompanying the operation (vertical movement) of the suspension device is reduced.

また、この実施形態において、電動機１０が操舵輪に取り付けられる場合には、図２、図５に示すように、電線である給電ケーブル１２は、懸架装置のキングピン軸Ｚｐを車輪側（すなわち車両１のＯＵＴ側）から回り込むように配置される。これによって、車輪の操舵にともなう、キングピン軸Ｚｐを中心とした電動機１０の回動による給電ケーブル１２の曲げやねじれを低減する。なお、この実施形態では、図５に示すように、給電ケーブル１２が端子部１１から引き出される方向（矢印Ｃ方向）と、電動機回転軸Ｚｒとは略直交しているが、給電ケーブル１２が端子部１１から引き出される方向はこれに限定されるものではない。   Further, in this embodiment, when the electric motor 10 is attached to a steered wheel, as shown in FIGS. 2 and 5, the power supply cable 12, which is an electric wire, is connected to the kingpin axis Zp of the suspension device on the wheel side (that is, the vehicle 1 Is arranged so as to wrap around from the OUT side). As a result, bending and twisting of the power supply cable 12 due to the rotation of the electric motor 10 around the kingpin axis Zp accompanying the steering of the wheel is reduced. In this embodiment, as shown in FIG. 5, the direction in which the power feeding cable 12 is pulled out from the terminal portion 11 (arrow C direction) and the motor rotation axis Zr are substantially orthogonal, but the power feeding cable 12 is a terminal. The direction drawn from the part 11 is not limited to this.

上述したような構成によって、この実施形態に係る電線の配線構造では、既存の構成を利用して、懸架装置の上下動や車輪の操舵にともなう電動機１０の上下動や回動に起因する給電ケーブル１２の曲げやねじれを低減できる。その結果、この実施形態に係る電線の配線構造では、部品点数を増加させることなく、給電ケーブル１２の耐久性が低下するおそれを極めて低くして、給電ケーブル１２の耐久性低下を効果的に抑制できる。   With the configuration as described above, in the wire wiring structure according to this embodiment, the existing structure is used, and the power supply cable resulting from the vertical movement and rotation of the electric motor 10 accompanying the vertical movement of the suspension device and the steering of the wheel 12 bending and twisting can be reduced. As a result, in the wiring structure of the electric wire according to this embodiment, the possibility that the durability of the power feeding cable 12 is reduced without increasing the number of parts is extremely reduced, and the durability reduction of the power feeding cable 12 is effectively suppressed. it can.

図６は、電線の接続部から電線が引き出される方向を、キングピン軸と略平行にした電線の配線構造を示す斜視図である。図７−１、図７−２は、電線の接続部から電線が引き出される方向を、キングピン軸と略平行にした電線の配線構造における電線の動きを説明する概念図である。図８−１、図８−２は、この実施形態に係る電線の配線構造における電線の動きを説明する概念図である。図６に示す電線の配線構造では、電動機１１０の端子部（電線の接続部）１１１から給電ケーブル（電線）１１２が引き出される方向（矢印Ｃ方向）が、キングピン軸Ｚｐと略平行になっている。この状態で、電線固定手段であるケーブルクランプ１１３によって給電ケーブル１１２が懸架装置のアッパーアーム１２０Ｕに固定されている。   FIG. 6 is a perspective view showing a wiring structure of the electric wire in which the direction in which the electric wire is drawn out from the connecting portion of the electric wire is substantially parallel to the kingpin axis. FIGS. 7A and 7B are conceptual diagrams for explaining the movement of the electric wire in the electric wire wiring structure in which the direction in which the electric wire is drawn out from the connecting portion of the electric wire is substantially parallel to the kingpin axis. FIGS. 8-1 and FIGS. 8-2 are the conceptual diagrams explaining the movement of the electric wire in the wiring structure of the electric wire which concerns on this embodiment. In the electric wire wiring structure shown in FIG. 6, the direction in which the feeding cable (electric wire) 112 is drawn from the terminal portion (electric wire connecting portion) 111 of the electric motor 110 (arrow C direction) is substantially parallel to the kingpin axis Zp. . In this state, the feeding cable 112 is fixed to the upper arm 120U of the suspension device by the cable clamp 113 which is a wire fixing means.

電線の接続部から電線が引き出される方向を、キングピン軸と略平行にした電線の配線構造では、図７−１に示すように、懸架装置の動作にともない電動機１１０が上方へ動くことによって、給電ケーブル１１２のＡで示す部分における曲げの半径が小さくなる。また、図７−２に示すように、車輪の操舵にともなう、キングピン軸Ｚｐを中心とした電動機１１０の回動（図７−２中における矢印Ｋ方向への動き）により、給電ケーブル１１２のＢで示す部分にねじれが発生する。このように、図６に示す電線の配線構造では、電線の接続部である端子部１１１から電線の固定部であるケーブルクランプ１１３までの間における給電ケーブル１１２に、曲げ及びねじりが同時に、あるいは交互に作用することによって、給電ケーブル１１２が疲労し、耐久性低下を招くことがある。   In the wiring structure of the electric wire in which the direction in which the electric wire is drawn out from the connecting portion of the electric wire is substantially parallel to the kingpin axis, as shown in FIG. 7A, the electric motor 110 moves upward in accordance with the operation of the suspension device. The radius of bending at the portion indicated by A of the cable 112 is reduced. Further, as shown in FIG. 7-2, the rotation of the electric motor 110 around the kingpin axis Zp (movement in the direction of arrow K in FIG. Twist occurs in the part indicated by. As described above, in the electric wire wiring structure shown in FIG. 6, bending and twisting are simultaneously or alternately applied to the feeding cable 112 between the terminal portion 111 that is the connecting portion of the electric wire and the cable clamp 113 that is the fixing portion of the electric wire. By acting on the power supply cable 112, the power supply cable 112 may be fatigued, resulting in a decrease in durability.

一方、この実施形態に係る電線の配線構造では、上述したように、電線の接続部である端子部１１から電線である給電ケーブル１２が引き出される方向は、キングピン軸Ｚｐと交差するように、より好ましくは略直交するように構成される。これによって、図８−１に示すように、懸架装置の動作にともなって電動機１０が上方に動くことに起因する、給電ケーブル１２のＡで示す部分における曲げの半径変化、及び給電ケーブル１２のねじれは小さくなる。   On the other hand, in the wiring structure of the electric wire according to this embodiment, as described above, the direction in which the power feeding cable 12 that is the electric wire is drawn out from the terminal portion 11 that is the electric wire connecting portion intersects with the kingpin axis Zp. Preferably, it is configured to be substantially orthogonal. As a result, as shown in FIG. 8A, the bending radius change in the portion indicated by A of the feeding cable 12 and the twisting of the feeding cable 12 due to the electric motor 10 moving upward with the operation of the suspension device. Becomes smaller.

また、端子部１１から給電ケーブル１２が引き出される位置の水平面からの距離は、給電ケーブル１２が配置されるアッパーアーム２０Ｕの水平面からの距離と同等としてある。これによって、車輪の操舵にともないキングピン軸Ｚｐを中心として電動機１０が回動しても、給電ケーブル１２はキングピン軸Ｚｐに対して略水平の状態で曲げられるので、電動機１０の回動（図８−２中における矢印Ｋ方向への動き）に起因する給電ケーブル１２のねじれを抑制できる。   Further, the distance from the horizontal plane where the power supply cable 12 is drawn out from the terminal portion 11 is equivalent to the distance from the horizontal plane of the upper arm 20U where the power supply cable 12 is arranged. As a result, even if the electric motor 10 rotates about the kingpin axis Zp as the wheels are steered, the feeding cable 12 is bent in a substantially horizontal state with respect to the kingpin axis Zp. -2 can be prevented from twisting due to the movement in the arrow K direction).

また、図８−２に示すように、給電ケーブル１２がキングピン軸Ｚｐを車輪側から回り込むように配置されるので、車輪の操舵にともなう、キングピン軸Ｚｐを中心とした電動機１０の回動に起因する給電ケーブル１２の動きを抑制することができる。その結果、給電ケーブル１２のＢで示す部分におけるねじれや曲げをより効果的に低減して、給電ケーブル１２に対する負荷を低減できる。   Further, as shown in FIG. 8B, since the power feeding cable 12 is arranged so as to go around the kingpin shaft Zp from the wheel side, it is caused by the rotation of the electric motor 10 around the kingpin shaft Zp accompanying the steering of the wheel. The movement of the feeding cable 12 can be suppressed. As a result, it is possible to more effectively reduce twisting and bending at the portion indicated by B of the power supply cable 12 and reduce the load on the power supply cable 12.

このように、この実施形態に係る電線の配線構造では、電線の接続部である端子部１１から電線の固定部であるケーブルクランプ１３までの間における給電ケーブル１２に発生する曲げ及びねじりを低減できるので、別部材を設けることなく、給電ケーブル１２が疲労することによる耐久性低下を効果的に抑制できる。   Thus, in the wiring structure of the electric wire according to this embodiment, bending and twisting generated in the power feeding cable 12 between the terminal portion 11 that is a connecting portion of the electric wire and the cable clamp 13 that is a fixing portion of the electric wire can be reduced. Therefore, it is possible to effectively suppress a decrease in durability due to fatigue of the feeding cable 12 without providing another member.

ここで、電線の接続部から前記電線が引き出される方向とキングピン軸とが交差する交差角度θ（図４参照）は、電動機１０の上下動による給電ケーブル１２の曲げやねじれを抑制する観点から概ね６０度以上が好ましく、より効果的に給電ケーブル１２の曲げやねじれを抑制できる。理想的には電線の接続部から前記電線が引き出される方向とキングピン軸とを略直交（８５度〜９５度）させることが好ましい。   Here, the crossing angle θ (see FIG. 4) at which the direction in which the electric wire is drawn out from the connecting portion of the electric wire and the kingpin axis intersect is generally from the viewpoint of suppressing bending and twisting of the power feeding cable 12 due to the vertical movement of the electric motor 10. 60 degree | times or more is preferable and can suppress the bending and twist of the electric power feeding cable 12 more effectively. Ideally, the direction in which the electric wire is drawn out from the connecting portion of the electric wire and the kingpin axis are preferably substantially orthogonal (85 degrees to 95 degrees).

図９−１〜図９−３、図１０及び図１１は、端子部から給電ケーブルが引き出される方向の規定方法を説明する概念図である。図９−１〜図９−３に示す例は、電線の接続部から前記電線が引き出される方向（図中の矢印Ｃ）が、懸架装置のリンクに取り付けられた電動機１０が移動する方向（図中のｌｓ）に対して交差（この実施形態では略直交）するようになっている。電線の接続部から前記電線が引き出される方向をこのようにすると、懸架装置の上下動にともなう電動機１０の上下動による給電ケーブル１２の曲げやねじれが極めて低減されるので、給電ケーブル１２の耐久性低下を効果的に抑制できる。   9A to 9C, 10, and 11 are conceptual diagrams illustrating a method for defining the direction in which the power feeding cable is drawn from the terminal portion. In the example shown in FIGS. 9-1 to 9-3, the direction in which the electric wire is drawn out from the connecting portion of the electric wire (arrow C in the figure) is the direction in which the electric motor 10 attached to the link of the suspension device moves (see FIG. 9). Ls) in the middle (in this embodiment, substantially orthogonal). When the direction in which the electric wire is drawn out from the connecting portion of the electric wire is made in this way, the bending and twisting of the power feeding cable 12 due to the vertical movement of the electric motor 10 accompanying the vertical movement of the suspension device is extremely reduced. Reduction can be effectively suppressed.

電線の接続部から前記電線が引き出される方向と、懸架装置の動作（上下動）とともに電動機が移動する方向とが交差する交差角度θ（図４参照）は、電動機１０の上下動による給電ケーブル１２の曲げやねじれを抑制する観点から６０度以上とするが、７０度以上とすることがより好ましい。さらには、前記交差角度θは８０度以上が好ましい。このように、交差角度θは、９０度に近い方がより効果的に給電ケーブル１２の曲げやねじれを抑制でき、理想的には電線の接続部から前記電線が引き出される方向と懸架装置の動作（上下動）とともに電動機が移動する方向とを略直交（８５度〜９５度）させることが好ましい。   The crossing angle θ (see FIG. 4) at which the direction in which the electric wire is drawn out from the connecting portion of the electric wire and the direction in which the motor moves together with the operation (vertical movement) of the suspension device is the feeding cable 12 due to the vertical movement of the electric motor 10. From the viewpoint of suppressing bending and twisting, the angle is set to 60 ° or more, but more preferably 70 ° or more. Furthermore, the intersection angle θ is preferably 80 degrees or more. As described above, when the crossing angle θ is close to 90 degrees, bending and twisting of the feeding cable 12 can be more effectively suppressed, and ideally, the direction in which the wire is drawn out from the connecting portion of the wire and the operation of the suspension device It is preferable to make the direction in which the motor moves together with (vertical movement) substantially orthogonal (85 to 95 degrees).

懸架装置が上下動すると、これにともなって懸架装置のリンクに取り付けられる電動機１０も上下動する。図９−１〜図９−３に示す例では、実線で示す位置から点線で示す位置まで電動機１０が移動可能とすると、電動機１０の移動にともない、電動機１０の回転軸Ｚｒも電動機１０と同じ距離だけ移動する。電動機回転軸ＺｒがＺｒ1で示す位置にあるとき、電動機１０は最も下の位置にあるとする（リバウンド側、すなわち伸び側の最大値）。一方電動機回転軸ＺｒがＺｒ2で示す位置にあるとき、電動機１０は最も上の位置にあるとする（バウンド側、すなわち縮み側の最大値）。 When the suspension device moves up and down, the motor 10 attached to the link of the suspension device also moves up and down. In the example shown in FIGS. 9A to 9C, if the electric motor 10 can move from the position indicated by the solid line to the position indicated by the dotted line, the rotation axis Zr of the electric motor 10 is the same as that of the electric motor 10 as the electric motor 10 moves. Move a distance. When motor rotation shaft Zr is in the position shown in Zr 1, the motor 10 is to be in the lowermost position (the maximum value of the rebound, i.e., elongation-side). On the other hand, when the motor rotation axis Zr is at the position indicated by Zr 2 , the motor 10 is assumed to be at the uppermost position (maximum value on the bounce side, that is, the contraction side).

ある懸架装置において、電動機１０の最大可動範囲は、リバウンド側の最大値からバウンド側の最大値まで（Ｚｒ1からＺｒ2まで）である。電動機１０に特定点Ｐを決め、電動機１０のリバウンド側の最大値における特定点Ｐと、バウンド側の最大値における特定点Ｐとを結んだ直線ｌｓが伸びる方向を、電動機１０が移動する方向とする。特定点Ｐは、電動機１０の動作前後で電動機１０の同一位置を表す点であればよく、例えば、電動機回転軸Ｚｒ上における、前記電動機回転軸Ｚｒと平行な方向における電動機１０の中心ＣＬとする。 In a certain suspension system, the maximum movable range of the electric motor 10 is from the maximum value on the rebound side to the maximum value on the bound side (from Zr 1 to Zr 2 ). The specific point P is determined for the electric motor 10, and the direction in which the electric motor 10 moves is the direction in which the straight line ls connecting the specific point P at the maximum value on the rebound side of the electric motor 10 and the specific point P at the maximum value on the bounce side extends. To do. The specific point P may be a point that represents the same position of the electric motor 10 before and after the operation of the electric motor 10, and is, for example, the center CL of the electric motor 10 in the direction parallel to the electric motor rotation axis Zr on the electric motor rotation axis Zr. .

図９−３は、いわゆるトレーリングアーム方式の懸架装置において、電動機１０が移動する方向を示している。トレーリングアームＴＬによる懸架装置では、通常電動機１０の回転軸方向に対する移動はない点を考慮して、電動機１０が移動する方向は、上述したように決定できる。すなわち、リバウンド側の最大値を示す電動機１０の回転軸をＺｒ1で示し、バウンド側の最大値を示す電動機１０の回転軸をＺｒ2で示すと、Ｚｒ1とＺｒ2とを結ぶ直線ｌｓが伸びる方向が、電動機１０が移動する方向となる。 FIG. 9-3 shows a direction in which the electric motor 10 moves in a so-called trailing arm suspension. In the suspension device using the trailing arm TL, the direction in which the electric motor 10 moves can be determined as described above in consideration of the fact that the electric motor 10 does not normally move in the direction of the rotation axis. That is, when the rotation axis of the electric motor 10 indicating the maximum value on the rebound side is indicated by Zr 1 and the rotation axis of the electric motor 10 indicating the maximum value on the bounce side is indicated by Zr 2 , a straight line ls connecting Zr 1 and Zr 2 is obtained. The extending direction is the direction in which the electric motor 10 moves.

図１０は、車両１の車輪２が水平面ＧＬに設置されている状態において、電動機１０に備えられる電線の接続部である端子部１１から給電ケーブル１２が引き出される方向（矢印Ｃ方向）を、水平面ＧＬと略平行としている。また、図１１は、電動機１０に備えられる電線の接続部である端子部１１から給電ケーブル１２が引き出される方向（矢印Ｃ方向）を、懸架装置のリンク（この例ではアッパーアーム２０Ｕ）と略平行にしている。電線の接続部から前記電線が引き出される方向をこのようにすると、懸架装置の上下動にともなう電動機１０の上下動による給電ケーブル１２の曲げやねじれは極めて低減されるので、給電ケーブル１２の耐久性低下を効果的に抑制できる。   FIG. 10 shows a direction (arrow C direction) in which the feeding cable 12 is pulled out from the terminal portion 11 which is a connecting portion of the electric wire provided in the electric motor 10 in a state where the wheels 2 of the vehicle 1 are installed on the horizontal plane GL. It is substantially parallel to GL. Further, in FIG. 11, the direction (arrow C direction) in which the feeding cable 12 is pulled out from the terminal portion 11 which is a connecting portion of the electric wire provided in the electric motor 10 is substantially parallel to the suspension link (upper arm 20U in this example). I have to. When the direction in which the electric wire is drawn out from the connecting portion of the electric wire is made in this way, the bending and twisting of the power feeding cable 12 due to the vertical movement of the electric motor 10 accompanying the vertical movement of the suspension device is extremely reduced. Reduction can be effectively suppressed.

なお、図１０、図１１に示すように、電線の接続部から前記電線が引き出される方向（矢印Ｃ方向）と、水平面ＧＬ（図１０）やアッパーアーム２０Ｕ（図１１）とは略平行とすることが好ましいが、電線の接続部から前記電線が引き出される方向（矢印Ｃ方向）は、所定以下の角度であれば、水平面ＧＬ（図１０）やアッパーアーム２０Ｕ（図１１）とは交差してもよい。電線の接続部から前記電線が引き出される方向（矢印Ｃ方向）と、水平面ＧＬ（図１０）やアッパーアーム２０Ｕ（図１１）とのなす角度は、電動機１０の上下動による給電ケーブル１２の曲げやねじれを抑制する観点から３０度以下とするが、前記角度は、０度に近い方がより効果的に給電ケーブル１２の曲げやねじれを抑制でき、理想的には上述したように、電線の接続部から前記電線が引き出される方向（矢印Ｃ方向）と、水平面ＧＬ（図１０）やアッパーアーム２０Ｕ（図１１）とは略平行（−５度〜５度）とすることが好ましい。   As shown in FIGS. 10 and 11, the direction in which the electric wire is drawn out from the connecting portion of the electric wire (arrow C direction) is substantially parallel to the horizontal plane GL (FIG. 10) and the upper arm 20U (FIG. 11). Preferably, the direction in which the electric wire is drawn out from the connecting portion of the electric wire (arrow C direction) intersects the horizontal plane GL (FIG. 10) and the upper arm 20U (FIG. 11) if the angle is a predetermined angle or less. Also good. The angle formed by the direction in which the electric wire is drawn out from the connecting portion of the electric wire (arrow C direction) and the horizontal plane GL (FIG. 10) or the upper arm 20U (FIG. 11) Although the angle is set to 30 degrees or less from the viewpoint of suppressing twisting, the angle close to 0 degrees can more effectively suppress bending and twisting of the feeding cable 12, and ideally as described above It is preferable that the direction in which the electric wire is drawn from the section (the direction of arrow C) and the horizontal plane GL (FIG. 10) and the upper arm 20U (FIG. 11) are substantially parallel (−5 degrees to 5 degrees).

図１２、図１３は、懸架装置のリンクに電線を沿わせて配置する他の例を示す説明図である。図１２に示す電線の配線構造のように、給電ケーブル１２はアッパーアーム２０Ｕの下側に沿わせて配置して、ケーブルクランプ１３で固定してもよい。このようにすると、アッパーアーム２０Ｕによる給電ケーブル１２の保護を図ることができる。   12 and 13 are explanatory views showing another example in which the electric wire is arranged along the link of the suspension device. Like the wiring structure of the electric wire shown in FIG. 12, the power feeding cable 12 may be arranged along the lower side of the upper arm 20 </ b> U and fixed by the cable clamp 13. If it does in this way, protection of the electric power feeding cable 12 by the upper arm 20U can be aimed at.

また、図１３に示す電線の配線構造のように、給電ケーブル１２をロワーアーム２０Ｌに沿わせて配置してもよい。この場合、電線の接続部である端子部１１は、電動機１０の下側（すなわちロワーアーム２０Ｌ側）に設けられる。そして、給電ケーブル１２はロワーアーム２０Ｌの上側、又は下側に沿わせて配置して、ケーブルクランプ１３で固定する。給電ケーブル１２をロワーアーム２０Ｌに沿わせて配置する場合、給電ケーブル１２をロワーアーム２０Ｌの上側に配置すると、ロワーアーム２０Ｌによって地面からの飛び石や障害物等から給電ケーブル１２を保護できるので、より好ましい。   Moreover, you may arrange | position the electric power feeding cable 12 along the lower arm 20L like the wiring structure of the electric wire shown in FIG. In this case, the terminal part 11 which is a connection part of an electric wire is provided under the electric motor 10 (namely, the lower arm 20L side). The power feeding cable 12 is arranged along the upper side or the lower side of the lower arm 20L, and is fixed by the cable clamp 13. When the power feeding cable 12 is arranged along the lower arm 20L, it is more preferable to arrange the power feeding cable 12 on the upper side of the lower arm 20L because the lower arm 20L can protect the power feeding cable 12 from a stepping stone or an obstacle from the ground.

図１４は、電線の接続部の位置を示す説明図である。上記説明において、電線の接続部である端子部１１は、電動機１０の側面（電動機１０の回転軸Ｚｒと平行な面）に取り付けられていた（図２参照）。図１４に示すように、端子部１１を電動機１０の背面（電動機１０と回転軸Ｚｒと直交する面の車両側）に取り付けてもよい。この場合、端子部１１から給電ケーブル１２が引き出される方向は、キングピン軸Ｚｐあるいは電動機１０が移動する方向と略直交するように構成される。端子部１１を電動機１０の背面に取り付ければ、電動機１０の径方向における寸法を抑えることができるので、ホイール内に電動機１０を配置するインホイールモータ方式の構成には好ましい。   FIG. 14 is an explanatory diagram showing the position of the connecting portion of the electric wire. In the above description, the terminal portion 11 that is a connecting portion of the electric wire is attached to the side surface of the electric motor 10 (a surface parallel to the rotation axis Zr of the electric motor 10) (see FIG. 2). As shown in FIG. 14, the terminal portion 11 may be attached to the back surface of the electric motor 10 (the vehicle side of the surface orthogonal to the electric motor 10 and the rotation axis Zr). In this case, the direction in which the power feeding cable 12 is drawn out from the terminal portion 11 is configured to be substantially orthogonal to the direction in which the kingpin axis Zp or the electric motor 10 moves. If the terminal part 11 is attached to the back surface of the electric motor 10, the dimension in the radial direction of the electric motor 10 can be suppressed, which is preferable for the configuration of the in-wheel motor system in which the electric motor 10 is arranged in the wheel.

図１５は、この実施形態に係る電線の配線構造を、いわゆるストラット形式の懸架装置に適用した例を示す斜視図である。この電線の配線構造においては、電動機１０はストラットシェル２１に、ブラケット２１Ｂを介して取り付けられる。電線の接続部である端子部１１は、電動機１０の下側（すなわちロワーアーム２０Ｌ側）に設けられており、給電ケーブル１２は、ロワーアーム２０Ｌに沿わせて配置されて、ケーブルクランプ１３でロワーアーム２０Ｌに固定される。   FIG. 15 is a perspective view showing an example in which the wiring structure of the electric wire according to this embodiment is applied to a so-called strut-type suspension device. In the wire wiring structure, the electric motor 10 is attached to the strut shell 21 via a bracket 21B. The terminal portion 11 that is a connecting portion of the electric wire is provided on the lower side of the electric motor 10 (that is, the lower arm 20L side), and the feeding cable 12 is disposed along the lower arm 20L, and is connected to the lower arm 20L by the cable clamp 13. Fixed.

以上、この実施形態では、いわゆるインホイールモータ形式において、電動機に接続される電線を、懸架装置のリンクに沿わせ、かつ電動機に設けられる電線の接続部から電線が引き出される位置を、電線を沿わせるリンクの高さと揃える。さらに、電動機に設けられる電線の接続部から電線が引き出される方向を、懸架装置の動作（上下動）とともに電動機が動作（上下動）する方向に対して所定の角度で交差、より好ましくは直交させる。   As described above, in this embodiment, in the so-called in-wheel motor type, the position of the electric wire connected to the motor along the link of the suspension device and the position where the electric wire is drawn out from the connection portion of the electric wire provided in the electric motor is aligned with the electric wire. Align with the height of the link to be made. Further, the direction in which the electric wire is drawn out from the connecting portion of the electric wire provided in the electric motor intersects at a predetermined angle with respect to the direction in which the electric motor operates (vertical movement) together with the operation of the suspension device (vertical movement), more preferably orthogonal .

これによって、懸架装置の上下動にともなって電動機が上下動したり、操舵輪に取り付けられる電動機がキングピン軸周りに回動したりする際には、別部材を設けることなく、電動機に設けられる接続部から引き出される電線の曲がりやねじれを低減できる。その結果、電線を電動機に取り付けるにあたって別部材を設けることなく、簡単な構造で電動機に接続される電線の耐久性低下を抑制できる。   As a result, when the electric motor moves up and down with the vertical movement of the suspension device, or when the electric motor attached to the steering wheel rotates around the kingpin shaft, the connection provided in the electric motor is not provided. Bending and twisting of the electric wire drawn out from the part can be reduced. As a result, it is possible to suppress a decrease in durability of the electric wire connected to the electric motor with a simple structure without providing another member when attaching the electric wire to the electric motor.

以上のように、本発明に係る電線の配線構造は、懸架装置のリンクに電動機が取り付けられる構造に有用であり、特に、簡単な構成で、電動機と接続される電線の耐久性低下を抑制することに適している。   As described above, the wiring structure of the electric wire according to the present invention is useful for a structure in which the electric motor is attached to the link of the suspension device, and particularly suppresses a decrease in durability of the electric wire connected to the electric motor with a simple configuration. Suitable for that.
