Description

本発明は、車両の燃料タンクから内燃機関へと燃料を供給するための燃料供給装置に関する。 The present invention relates to a fuel supply device for supplying fuel from a fuel tank of a vehicle to an internal combustion engine.

従来から、鞍乗り型車両に搭載された燃料タンク内の燃料を燃料ポンプで吸い込んで加圧した後、吐出することで内燃機関へと供給する燃料供給装置が知られている。 2. Description of the Related Art Conventionally, there has been known a fuel supply apparatus that supplies fuel to an internal combustion engine by sucking and pressurizing fuel in a fuel tank mounted on a saddle-ride type vehicle with a fuel pump and then discharging the fuel.

例えば、特許文献１に開示された燃料供給装置は、自動二輪車に搭載された燃料タンクの開口を塞ぐ蓋部を有したフランジと、該フランジに接続されるハウジングと、該ハウジングの内部に収納され燃料を吸入・吐出する燃料ポンプと、該燃料ポンプの吸入側に接続部材を介して接続されるサクションフィルタとを備え、前記フランジには、燃料ポンプを駆動させるためのリード線が接続されたコネクタが設けられる。 For example, a fuel supply device disclosed in Patent Document 1 is housed in a flange having a lid portion that closes an opening of a fuel tank mounted on a motorcycle, a housing connected to the flange, and the housing. A connector comprising a fuel pump for sucking and discharging fuel, and a suction filter connected to the suction side of the fuel pump via a connecting member, and a lead wire for driving the fuel pump is connected to the flange Is provided.

そして、上述した燃料供給装置を鞍型の燃料タンクへと設置する際、鞍型に分かれた燃料タンクの底壁は車両の前後方向に比べて車幅方向が短いため、前記底壁に設けられる開口を前後方向に沿って長尺な長孔形状とし、それに合わせて、燃料供給装置におけるフランジの蓋部を長円形状として前記開口を塞ぐように設置している。 When the fuel supply device described above is installed in a vertical fuel tank, the bottom wall of the vertical fuel tank is provided on the bottom wall because the vehicle width direction is shorter than the vehicle front-rear direction. The opening is formed in an elongated hole shape along the front-rear direction, and in accordance with this, the flange lid portion of the fuel supply apparatus is installed in an oblong shape so as to close the opening.

上述した特許文献１に係る燃料供給装置では、フランジの蓋部においてコネクタを燃料ポンプに対して軸方向に離れた位置に配置することで前記コネクタと前記燃料ポンプとが幅方向に重なることがないため、燃料ポンプの径方向となるフランジの幅寸法を抑えることができる一方で、前記燃料ポンプの軸方向に沿ったフランジの長手寸法が前記コネクタの分だけ大きくなってしまうという問題がある。 In the fuel supply device according to Patent Document 1 described above, the connector and the fuel pump do not overlap in the width direction by disposing the connector in the axial direction away from the fuel pump in the lid portion of the flange. Therefore, while it is possible to suppress the width dimension of the flange in the radial direction of the fuel pump, there is a problem that the longitudinal dimension of the flange along the axial direction of the fuel pump is increased by the amount of the connector.

本発明は、前記の課題を考慮してなされたものであり、蓋部材を幅方向及び長手方向に小型化することで開口部を小型化し燃料タンクへの搭載汎用性を高めることが可能な燃料供給装置を提供することを目的とする。 The present invention has been made in consideration of the above-described problems, and by reducing the size of the lid member in the width direction and the longitudinal direction, the fuel that can reduce the size of the opening and increase the versatility of mounting on the fuel tank. An object is to provide a supply device.

前記の目的を達成するために、本発明は、燃料タンク内に配置される燃料供給装置において、
燃料供給装置は、燃料タンクに開口した開口部を覆う蓋部材と、
蓋部材の面に沿ってその軸心が保持され、モータ部を収納するモータ本体と、モータ本体の端部から軸方向に突出し燃料を吐出する吐出口とを有した燃料ポンプと、
蓋部材において燃料タンクの外部と連通し、吐出口と接続される通路を有した吐出管路と、
蓋部材に設けられ、燃料タンクの内部から外部まで延在し燃料ポンプに対してリード線を介して電気的に接続される蓋部材側端子と、
を備え、
蓋部材の垂線方向から見て、燃料ポンプのうち少なくとも吐出口が蓋部材と重なり合う範囲内に配置されると共に、蓋部材側端子は、吐出管路において吐出口が接続される部位の吐出管路の径方向外縁とモータ本体の径方向外縁との間に配置され、且つ、燃料ポンプの軸方向において、少なくとも一部が吐出口と重なり合う範囲に配置されることを特徴とする。 To achieve the above object, the present invention provides a fuel supply apparatus disposed in a fuel tank.
The fuel supply device includes a lid member that covers an opening that opens in the fuel tank;
A fuel pump having a motor body in which the axis is held along the surface of the lid member, housing the motor unit, and a discharge port projecting in the axial direction from the end of the motor body and discharging fuel;
A discharge line that communicates with the outside of the fuel tank in the lid member and has a passage connected to the discharge port;
A lid member-side terminal provided on the lid member, extending from the inside of the fuel tank to the outside and electrically connected to the fuel pump via a lead wire;
With
When viewed from the direction perpendicular to the lid member, at least the discharge port of the fuel pump is disposed in a range where it overlaps the lid member, and the terminal on the lid member side is a discharge line at a portion where the discharge port is connected in the discharge line Between the radial outer edge of the motor and the radial outer edge of the motor body, and in the axial direction of the fuel pump, at least a part of the outer edge overlaps the discharge port.

本発明によれば、燃料供給装置を構成する蓋部材において、燃料タンクの内部から外部まで延在し燃料ポンプに対してリード線を介して電気的に接続される蓋部材側端子を備え、蓋部材の垂線方向から見て、少なくとも燃料ポンプの吐出口が蓋部材と重なり合う範囲内に配置され、蓋部材側端子が吐出管路において吐出口が接続される部位の吐出管路の径方向外縁とモータ本体の径方向外縁との間に配置されると共に、蓋部材側端子の少なくとも一部が、燃料ポンプの軸方向において吐出口と重なり合う範囲内に配置される。 According to the present invention, the lid member constituting the fuel supply device includes the lid member-side terminal that extends from the inside of the fuel tank to the outside and is electrically connected to the fuel pump via the lead wire. When viewed from the direction perpendicular to the member, at least the discharge port of the fuel pump is arranged in a range where it overlaps with the lid member, and the lid member side terminal is connected to the radially outer edge of the discharge pipeline at the site where the discharge port is connected in the discharge pipeline It is arranged between the outer peripheral edge of the motor body in the radial direction and at least a part of the lid member side terminal is arranged in a range overlapping with the discharge port in the axial direction of the fuel pump.

従って、蓋部材側端子を、蓋部材の垂線方向から見てモータ本体の径方向外縁と吐出管路の径方向外縁との間に好適に配置できるため、モータ本体の径方向（幅方向）の突出が抑えられ蓋部材の幅方向寸法を小型化可能となる。また、燃料ポンプの軸方向（長手方向）においても吐出口と重なり合うように蓋部材側端子を配置することで、従来技術に係る燃料供給装置と比較し蓋部材の長手方向寸法も小型化できる。 Therefore, since the lid member side terminal can be suitably disposed between the radial outer edge of the motor body and the radial outer edge of the discharge pipe as viewed from the perpendicular direction of the lid member, the terminal in the radial direction (width direction) of the motor body Protrusion is suppressed and the size in the width direction of the lid member can be reduced. Further, by arranging the lid member side terminal so as to overlap the discharge port also in the axial direction (longitudinal direction) of the fuel pump, the longitudinal dimension of the lid member can be reduced as compared with the fuel supply device according to the prior art.

その結果、蓋部材の幅方向寸法及び長手方向寸法を共に小型化することで、この蓋部材によって塞がれる燃料タンクの開口部を小さくでき、それに伴って、燃料タンクに対する燃料供給装置の搭載汎用性を高めることが可能となる。 As a result, by reducing both the width direction dimension and the longitudinal direction dimension of the lid member, the opening of the fuel tank that is blocked by the lid member can be made smaller. It becomes possible to improve the nature.

また、蓋部材には、複数の蓋部材側端子を互いに仕切る隔壁部を備え、垂線方向から見て、隔壁部の全体を吐出管路において吐出口が接続される部位の吐出管路の径方向外縁とモータ本体の径方向外縁との間に配置し、且つ、燃料ポンプの軸方向において、少なくとも一部が吐出口と重なり合う範囲に配置するとよい。これにより、蓋部材側端子を互いに仕切る隔壁部を蓋部材に対して設けた場合でも、蓋部材が幅方向及び長手方向に大型化してしまうことなく小型化でき、それに伴って、燃料タンクの開口部を小型化できる。 In addition, the lid member includes a partition wall portion that partitions the plurality of lid member side terminals from each other, and when viewed from the perpendicular direction, the entire partition wall portion is in the radial direction of the portion of the discharge conduit where the discharge port is connected. It is good to arrange | position between an outer edge and the radial direction outer edge of a motor main body, and to arrange | position in the range which at least one part overlaps with a discharge port in the axial direction of a fuel pump. As a result, even when the partition member for partitioning the lid member side terminals from each other is provided on the lid member, the lid member can be downsized without increasing in size in the width direction and the longitudinal direction. The size can be reduced.

さらに、蓋部材側端子を、垂線方向に沿って蓋部材から燃料ポンプ側へと突出させ、リード線に接続されたリード線側端子を接続する際には、このリード線側端子を燃料ポンプ側から蓋部材側端子へと接続するための空間を確保できるため、蓋部材側となる蓋部材側端子への接続作業を容易に行うことができる。 Further, when the lid member side terminal protrudes from the lid member to the fuel pump side along the perpendicular direction and the lead wire side terminal connected to the lead wire is connected, the lead wire side terminal is connected to the fuel pump side. Since the space for connecting to the lid member side terminal can be ensured, the connection work to the lid member side terminal on the lid member side can be easily performed.

さらにまた、蓋部材の垂線方向から見て、モータ部の端子を、吐出口に対して蓋部材側端子の反対側に配置することにより、吐出口の接続される吐出管路周囲の空間を、垂線と直交する幅方向一方側で蓋部材側端子のためのスペースとし、幅方向他方側をモータ部の端子のためのスペースとして活用でき、蓋部材側端子及びモータ部の端子の幅方向への突出を抑えることで幅方向寸法の小型化を可能とする。 Furthermore, when viewed from the perpendicular direction of the lid member, by arranging the terminal of the motor unit on the opposite side of the lid member side terminal with respect to the discharge port, the space around the discharge conduit to which the discharge port is connected, One side in the width direction orthogonal to the perpendicular can be used as a space for the lid member side terminal, and the other side in the width direction can be used as a space for the terminal of the motor unit. By suppressing the protrusion, the size in the width direction can be reduced.

またさらに、モータ部の端子が、燃料ポンプの端部において周方向に沿って互いに離間して配置され、蓋部材側端子が、燃料ポンプの軸線に沿って一直線状に配置され、吐出管路の通路が、蓋部材の垂線方向に沿って延在し、通路の中心を、燃料ポンプの軸心に対して蓋部材側端子側にオフセットさせるとよい。これにより、燃料ポンプの長手方向から見た際、燃料ポンプにおけるモータ部の端子周囲の空間を十分に確保できるため、この端子に対するリード線の接続作業を容易に行うことが可能となる。 Furthermore, the terminals of the motor unit are arranged apart from each other along the circumferential direction at the end of the fuel pump, and the lid member side terminals are arranged in a straight line along the axis of the fuel pump. The passage may extend along the perpendicular direction of the lid member, and the center of the passage may be offset toward the lid member side terminal with respect to the axis of the fuel pump. As a result, when viewed from the longitudinal direction of the fuel pump, a sufficient space around the terminal of the motor portion in the fuel pump can be ensured, so that the lead wire can be easily connected to the terminal.

本発明によれば、以下の効果が得られる。 According to the present invention, the following effects can be obtained.

すなわち、燃料供給装置を構成する蓋部材において、燃料タンクの内部から外部まで延在し燃料ポンプに対してリード線を介して電気的に接続される蓋部材側端子を備え、蓋部材の垂線方向から見て、少なくとも燃料ポンプの吐出口を蓋部材と重なり合う範囲内に配置し、且つ、蓋部材側端子を吐出管路において吐出口が接続される部位の吐出管路の径方向外縁とモータ本体の径方向外縁との間に配置すると共に、蓋部材側端子の少なくとも一部を、燃料ポンプの軸方向において吐出口と重なり合う範囲に配置することで、蓋部材の垂線方向から見て蓋部材側端子のモータ本体の径方向（幅方向）の突出が抑えられ蓋部材の幅方向寸法を小型化できると共に、従来技術に係る燃料供給装置と比較して燃料ポンプの軸方向（長手方向寸法）も小型化できる。 That is, the lid member constituting the fuel supply device includes a lid member-side terminal that extends from the inside of the fuel tank to the outside and is electrically connected to the fuel pump via a lead wire, and the perpendicular direction of the lid member When viewed from the side, at least the discharge port of the fuel pump is arranged in a range overlapping with the lid member, and the outer edge in the radial direction of the discharge pipe and the motor body at the part where the discharge port is connected to the lid member side terminal And at least a part of the lid member side terminal in a range overlapping with the discharge port in the axial direction of the fuel pump, so that the lid member side is viewed from the perpendicular direction of the lid member. The protrusion in the radial direction (width direction) of the motor body of the terminal can be suppressed, and the width direction dimension of the lid member can be reduced, and the axial direction (longitudinal direction dimension) of the fuel pump is also smaller than the fuel supply device according to the prior art. small Possible reduction.

その結果、蓋部材の幅方向寸法及び長手方向寸法を共に小型化することで、この蓋部材によって塞がれる燃料タンクの開口部を小さくでき、それに伴って、燃料タンクに対する燃料供給装置の搭載汎用性を高めることができる。 As a result, by reducing both the width direction dimension and the longitudinal direction dimension of the lid member, the opening of the fuel tank that is blocked by the lid member can be made smaller. Can increase the sex.

本発明の実施の形態に係る燃料供給装置１０は、基本的には以上のように構成されるものであり、次にその動作並びに作用効果について説明する。 The fuel supply apparatus 10 according to the embodiment of the present invention is basically configured as described above. Next, the operation and effects thereof will be described.

先ず、図示しないコントローラからの制御信号が、カプラを介して蓋部材１８におけるコネクタ部３２の端子片４０へと入力され、この制御信号が、前記端子片４０から第２接続端子１２０、リード線４２及び第１接続端子１１８を通じてモータ端子１１６から燃料ポンプ２０のモータ部１１２へと入力される。これにより、燃料ポンプ２０のモータ部１１２が駆動し、それに伴ってポンプ部１１０が回転駆動することで、燃料タンク１２の内部に蓄えられた燃料がフィルタ２４を通過してアタッチメント１２８及びエンドブロック５６の吸入通路１０８を通じて吸入口１２２から燃料ポンプ２０の内部へと吸入される。 First, a control signal from a controller (not shown) is input to the terminal piece 40 of the connector portion 32 of the lid member 18 through the coupler, and this control signal is transmitted from the terminal piece 40 to the second connection terminal 120 and the lead wire 42. In addition, the signal is input from the motor terminal 116 to the motor unit 112 of the fuel pump 20 through the first connection terminal 118. As a result, the motor unit 112 of the fuel pump 20 is driven, and the pump unit 110 is rotationally driven accordingly, so that the fuel stored in the fuel tank 12 passes through the filter 24 and the attachment 128 and the end block 56. Is sucked from the suction port 122 into the fuel pump 20 through the suction passage 108.

そして、燃料ポンプ２０へと吸入された燃料は、ポンプ部１１０の駆動作用下に吐出口１２４からハウジング５４の第１燃料通路７４へと吐出された後、第３燃料通路９２から蓋部材１８の吐出部４６を通じて燃料チューブ４７へと導出される。その後、燃料チューブ４７を通じて内燃機関のインジェクタへと燃料が供給される。 The fuel sucked into the fuel pump 20 is discharged from the discharge port 124 to the first fuel passage 74 of the housing 54 under the driving action of the pump unit 110, and then from the third fuel passage 92 to the lid member 18. It is led out to the fuel tube 47 through the discharge part 46. Thereafter, fuel is supplied to the injector of the internal combustion engine through the fuel tube 47.

また、第１燃料通路７４から第３燃料通路９２へと供給され余剰となった燃料は、該第３燃料通路９２から第２燃料通路７６を通じてプレッシャレギュレータ８０へと供給され、このプレッシャレギュレータ８０が燃料の圧力によって弁開することで、前記燃料がプレッシャレギュレータ８０を通過して導出孔１００から燃料タンク１２内へと排出される。 The surplus fuel supplied from the first fuel passage 74 to the third fuel passage 92 is supplied from the third fuel passage 92 to the pressure regulator 80 through the second fuel passage 76, and the pressure regulator 80 By opening the valve by the pressure of the fuel, the fuel passes through the pressure regulator 80 and is discharged from the outlet hole 100 into the fuel tank 12.

以上のように、本実施の形態では、燃料供給装置１０を構成する蓋部材１８において、燃料ポンプ２０のモータ部１１２にリード線４２を介して接続される端子片４０が、図３に示される前記蓋部材１８と直交する鉛直方向から見て、燃料ポンプ２０の吐出口１２４が収納されるハウジング５４の幅方向外縁５４ａと燃料ポンプ２０のケース１１４において径方向最大幅となる外縁部１１４ａとの間に配置されるため、前記端子片４０の幅方向（矢印Ｃ１方向）への突出が抑えられ、それに伴って蓋部材１８の幅方向寸法を小型化可能となる。 As described above, in the present embodiment, the terminal piece 40 connected to the motor unit 112 of the fuel pump 20 via the lead wire 42 in the lid member 18 constituting the fuel supply device 10 is shown in FIG. A width direction outer edge 54a of the housing 54 in which the discharge port 124 of the fuel pump 20 is accommodated and an outer edge portion 114a having a maximum radial width in the case 114 of the fuel pump 20 when viewed from the vertical direction orthogonal to the lid member 18. Since the terminal piece 40 is disposed between the two, the protrusion of the terminal piece 40 in the width direction (arrow C1 direction) is suppressed, and the width direction dimension of the lid member 18 can be reduced accordingly.

また、燃料ポンプ２０の軸方向（矢印Ａ、Ｂ方向）において、図３に示されるように、複数の端子片４０の少なくとも一部を、前記燃料ポンプ２０の吐出口１２４と幅方向に重なるように配置することで、コネクタを燃料ポンプに対して軸方向に離れた位置に配置している従来技術に係る燃料供給装置と比較し、蓋部材１８の長手方向寸法を小型化できる。 Further, in the axial direction of the fuel pump 20 (in the directions of arrows A and B), as shown in FIG. 3, at least a part of the plurality of terminal pieces 40 overlaps the discharge port 124 of the fuel pump 20 in the width direction. As a result, the longitudinal dimension of the lid member 18 can be reduced as compared with the fuel supply device according to the prior art in which the connector is disposed at a position axially separated from the fuel pump.

その結果、蓋部材１８の幅方向寸法及び長手方向寸法を共に小型化することで、該蓋部材１８によって塞がれる燃料タンク１２の開口部１６を小さくできるため、燃料供給装置１０の前記燃料タンク１２に対する搭載汎用性を高めることが可能となる。 As a result, by reducing both the width direction dimension and the longitudinal direction dimension of the lid member 18, the opening 16 of the fuel tank 12 that is blocked by the lid member 18 can be made small, so that the fuel tank of the fuel supply device 10 can be reduced. The mounting versatility with respect to 12 can be improved.

さらに、蓋部材１８のベース部２６には、複数の端子片４０を互いに分離する端子接続部３０を備え、この端子接続部３０が前記ベース部２６と直交する鉛直方向から見て、ハウジング５４の幅方向外縁５４ａと燃料ポンプ２０におけるケース１１４の外縁部１１４ａとの間に配置され、しかも、前記燃料ポンプ２０の軸方向（矢印Ａ、Ｂ方向）において吐出口１２４と幅方向に重なるように配置されている。そのため、蓋部材１８のベース部２６に対して各端子片４０を分離する端子接続部３０を設けた場合でも、前記蓋部材１８が幅方向及び長手方向に大型化してしまうことが回避される。 Further, the base portion 26 of the lid member 18 is provided with a terminal connection portion 30 that separates the plurality of terminal pieces 40 from each other, and the terminal connection portion 30 of the housing 54 is viewed from a vertical direction orthogonal to the base portion 26. It arrange | positions between the width direction outer edge 54a and the outer edge part 114a of the case 114 in the fuel pump 20, and arrange | positions so that it may overlap with the discharge port 124 in the width direction in the axial direction (arrow A, B direction) of the said fuel pump 20. Has been. Therefore, even when the terminal connection part 30 which isolate | separates each terminal piece 40 with respect to the base part 26 of the cover member 18 is provided, it is avoided that the said cover member 18 enlarges in the width direction and a longitudinal direction.

さらにまた、端子片４０は、蓋部材１８において鉛直方向に延在し、端子接続部３０及びコネクタ部３２側へそれぞれ突出すると共に、前記端子接続部３０へ収納された端子片４０の上端に、リード線４２に接続された第２接続端子１２０を接続可能とすることで、この第２接続端子１２０を燃料ポンプ２０側となる上方から端子接続部３０の端子片４０へと接続するための空間を端子片４０の上方に確保できるため、蓋部材１８側となる端子片４０への第２接続端子１２０の接続作業を容易に行うことができる。 Furthermore, the terminal piece 40 extends in the vertical direction in the lid member 18, protrudes toward the terminal connection portion 30 and the connector portion 32, and at the upper end of the terminal piece 40 accommodated in the terminal connection portion 30, By enabling connection of the second connection terminal 120 connected to the lead wire 42, a space for connecting the second connection terminal 120 from the upper side on the fuel pump 20 side to the terminal piece 40 of the terminal connection portion 30. Can be secured above the terminal piece 40, and therefore, the connection work of the second connection terminal 120 to the terminal piece 40 on the lid member 18 side can be easily performed.

またさらに、蓋部材１８と直交する鉛直方向から見て、燃料ポンプ２０のモータ端子１１６が、吐出口１２４に対して端子接続部３０と反対側に配置されているため、前記吐出口１２４の接続される第１燃料通路７４近傍の空間を、幅方向一方側（矢印Ｃ１方向）で端子片４０のためのスペースとし、幅方向他方側（矢印Ｃ２方向）をモータ端子１１６のためのスペースとして活用でき、前記モータ端子１１６及び端子片４０の幅方向（矢印Ｃ１、Ｃ２方向）への張り出しを抑えることで幅方向寸法の大型化を防止できる。 Furthermore, since the motor terminal 116 of the fuel pump 20 is disposed on the opposite side of the terminal connection portion 30 with respect to the discharge port 124 when viewed from the vertical direction orthogonal to the lid member 18, the connection of the discharge port 124 is performed. The space near the first fuel passage 74 is used as a space for the terminal piece 40 on one side in the width direction (arrow C1 direction), and the other side in the width direction (arrow C2 direction) is used as a space for the motor terminal 116. In addition, by suppressing the motor terminal 116 and the terminal piece 40 from projecting in the width direction (arrow C1, C2 direction), an increase in size in the width direction can be prevented.

また、複数のモータ端子１１６が、燃料ポンプ２０の軸心Ｆを中心として周方向に沿って互いに離間するように配置され、前記燃料ポンプ２０の軸方向に沿って一直線状に配置された端子片４０の幅方向寸法に対し、前記モータ端子１１６の幅方向寸法が大きくなるが、第３燃料通路９２を燃料ポンプ２０の軸心Ｆに対して幅方向外側となる端子接続部３０側（矢印Ｃ１方向）へオフセットさせ配置することで、図４に示される燃料ポンプ２０の長手方向から見て、燃料ポンプ２０におけるモータ端子１１６の周囲空間を十分に確保することが可能となる。 A plurality of motor terminals 116 are arranged so as to be separated from each other along the circumferential direction around the axis F of the fuel pump 20, and are arranged in a straight line along the axial direction of the fuel pump 20. Although the width dimension of the motor terminal 116 is larger than the width dimension of 40, the terminal connecting portion 30 side (arrow C <b> 1) is located outside the third fuel passage 92 in the width direction with respect to the axis F of the fuel pump 20. 4), the space around the motor terminal 116 in the fuel pump 20 can be sufficiently secured as viewed from the longitudinal direction of the fuel pump 20 shown in FIG.

そのため、モータ端子１１６の前方側（矢印Ａ方向）からの第１接続端子１１８（リード線４２）の接続作業を上述した空間を利用して容易に行うことが可能となる。 Therefore, it is possible to easily connect the first connection terminal 118 (lead wire 42) from the front side (arrow A direction) of the motor terminal 116 using the space described above.
