Description
【発明の詳細な説明】 〔産業上の利用分野〕 本発明は、ラッチ用電磁石に関し、より詳しくは、コア部分と磁気飽和で動作す るラッチ用電磁石に関する。[Detailed description of the invention] [Industrial application field] The present invention relates to a latching electromagnet, and more specifically, the present invention relates to a latching electromagnet, and more particularly, to a latching electromagnet that operates with a core portion and magnetic saturation. This invention relates to a latch electromagnet.
ラッチ用電磁石は各種の用途で使用されている。1つの用途では、制御回路が、 電磁石に可動部材を止め位置に「ラッチする」動作を行わせる場合がある。さら に又、制御回路により、所定の力を有する機械装置を介して可動部材に対し止め 位置から「ラッチ解除」の動作を行わせる場合がある。しかし、もし電磁石の「 ラッチ動作」力が変化すると、機械装置の力が電磁力に打ち勝つのに十分でなく なる場合もある。その結果、可動部材は止め位置にラッチされたままで、おそら く制御装置がうまく作動しなくなる。 Latching electromagnets are used in a variety of applications. In one application, the control circuit is An electromagnet may act to "latch" the movable member into a stopped position. Sara Also, the control circuit causes a stop to the movable member via a mechanical device having a predetermined force. There are cases where the "latch release" operation is performed from the position. However, if the electromagnet's If the latching force changes, the force of the mechanical device is not sufficient to overcome the electromagnetic force. Sometimes it happens. As a result, the movable member remains latched in the parked position and may The control device may not operate properly.
他の用途では、止め位置で電子油圧制御の制御レバーをラッチするのに、電磁石 が設けられる。電磁石を消磁するか、オペレーターが手動で制御レバーを励磁状 態の電磁石から外すまで、制御レバーは止め位置にラッチされる。後者の場合は 、オペレーターは電磁力に打ち勝つ力を制御レバーにかけなければならない。In other applications, electromagnets are used to latch electro-hydraulic control levers in the stop position. is provided. Either the electromagnet is demagnetized or the operator manually energizes the control lever. The control lever is latched in the stop position until it is removed from the electromagnet. In the latter case , the operator must apply a force to the control lever that overcomes the electromagnetic force.
不都合なことに、従来の電磁石の設計ではほぼ一定の電磁力を発生することはで きなかった。例えば、従来の電磁石100を図1に示す。電磁石100はコア1 05、コイル1lO2接極子115を含む。励磁状態では、コイル110は接極 子115をコア105にラッチする電磁力を生じる。コイル110を消磁すると 、バネ120が接極子を中立位置へ付勢する。Unfortunately, conventional electromagnet designs cannot generate nearly constant electromagnetic forces. I couldn't come. For example, a conventional electromagnet 100 is shown in FIG. Electromagnet 100 is core 1 05, including coil 11O2 armature 115. In the energized state, the coil 110 is polarized An electromagnetic force is generated that latches the child 115 to the core 105. When the coil 110 is demagnetized , a spring 120 biases the armature to a neutral position.
図2に(接極子がコアにラッチされているとき)電磁力とコイル電流との間の関 係を例示するカー電流曲線を示す。運転中、コイル電流は最小値と最大値の間を 変動する。電流の変動は、コイルの温度と電圧の変化による。曲線が「急」なの で、その結果束じる電磁力は、過少な力と過大な力の間を変化し、制御レバーが 意図しない時に外れを起こしたり、大きすぎてオペレーターが動かせないような 力を生じる場合がある。Figure 2 shows the relationship between the electromagnetic force and the coil current (when the armature is latched to the core). 2 shows Kerr current curves illustrating the relationship between the two. During operation, the coil current varies between the minimum and maximum values. fluctuate. The variation in current is due to changes in coil temperature and voltage. The curve is “steep” The resulting electromagnetic force changes between too little and too much force, and the control lever It may come off unexpectedly or be too large for the operator to move. Force may be generated.
従来の電磁石の設計の他の望ましくない態様は、エアギャップ長さが変化するこ とに関係する。例えば図1に示すように、接極子115は電磁コアとラッチ状態 で「ぴったり接触するjように設計されている。しかし、エアギャップ長さが変 化し、そのため電磁力が変化することがある。例えば、製造公差、コアと接極子 の調整不良、電磁石部品の上に蓄積した(ちりやさび粒子等の)異物等、全ての ものがエアギャップ長さをかなり変化させる場合がある。エアギャップ長さがか なり変化し、コイル電流が変動するので、電磁力の制御が困難になる。Another undesirable aspect of conventional electromagnet design is that the air gap length varies. related to. For example, as shown in FIG. However, if the air gap length changes, , and therefore the electromagnetic force may change. For example, manufacturing tolerances, core and armature All electromagnetic components, such as misalignment, foreign matter (such as dust or rust particles) that has accumulated on the electromagnetic parts, etc. may vary the air gap length considerably. What is the air gap length? The coil current fluctuates, making it difficult to control the electromagnetic force.
本発明は、上述の問題の1つ又はそれ以上を克服しようとするものである。The present invention seeks to overcome one or more of the problems mentioned above.
本発明の1態様では、ラッチ用電磁石が提供される。電磁石は極表面、巻き線コ イル、接極子を持つコアを含む。コアは、磁束密度が飽和レベルまで局所的に増 加するような幾何学的配置を持つようにすると好都合である。 In one aspect of the invention, a latching electromagnet is provided. The electromagnet is located on the extreme surface, contains a core with an armature and an armature. The core has a magnetic flux density that locally increases to a saturation level. It is advantageous to have a geometric arrangement that adds

Designed with a shaped geometry that locally increases the density to saturation levels. It is. FIG. 4 shows a typical L-H curve for this type of electromagnet. y-axis is magnetic flux The X axis represents the density B, and the X axis represents the magnetic flux strength, ie, the strength of the magnetic field, H. The upper part of the curve (B sat) represents the region of saturation magnetic flux density. The magnetic flux saturation region occurs naturally in air. This corresponds to the B-H relationship.
1つの幾何学的配置を図3の実施例に示し、ここでコア305は内側部分315 上の飽和領域335を形成し、飽和磁束密度を提供する。より詳しくは、コア3 05の内側部分310にボア333を形成する。飽和領域335は、次式で計算 した所定の断面積へを有する。One geometry is shown in the embodiment of FIG. 3, where core 305 is connected to inner portion 315 An upper saturation region 335 is formed to provide a saturation magnetic flux density. For more information, see Core 3 A bore 333 is formed in the inner portion 310 of 05. The saturation region 335 is calculated using the following formula It has a predetermined cross-sectional area.
Bsat = (φ/A)= (Ni/RA) [1]式[1]を八について解 いて、 A= (Ni/ (R)(Bsat )) [2]ここに、φ=磁束 R−電磁気抵抗 N=コイル巻き数 i=コイル電流 り、=飽和領域の外直径 り、=飽和領域の内直径 飽和領域335の所定の領域は、コイル電流と温度が変化しても、磁束密度と電 磁力が少ししか変化しない。Bsat = (φ/A) = (Ni/RA) [1] Solving equation [1] for 8 There, A=(Ni/(R)(Bsat))) [2] Here, φ=magnetic flux R-electromagnetic resistance N = number of coil turns i = coil current = outer diameter of saturated region = inner diameter of saturated region A predetermined region of the saturation region 335 maintains the magnetic flux density and current even as the coil current and temperature change. The magnetic force changes only slightly.
1つの幾何学的配置を上述したが、他の幾何学的配置で容易に代用できることは 当業者には明らかである。従って、本発明は、図3に示し上述した幾何学的配置 に制限されない。Although one geometrical arrangement has been described above, other geometrical arrangements can easily be substituted. It will be clear to those skilled in the art. Accordingly, the present invention utilizes the geometric arrangement shown in FIG. 3 and described above. not limited to.
結果として得られる力と電流の曲線を図5に示す。所望の電磁力が所定の作動ポ イントで作用する。図示するように、所定の作動ポイントに対応する曲線部分は 、従来の電磁石の作動ポイントと比較して比較的「フラット」である。従って、 従来の電磁石と比較して、コイル電流が変動しても電磁力は少ししが変化しない 。The resulting force and current curves are shown in Figure 5. the desired electromagnetic force at a given actuation point. Acts on the int. As shown, the curved section corresponding to a given actuation point is , is relatively "flat" compared to the actuation point of conventional electromagnets. Therefore, Compared to conventional electromagnets, the electromagnetic force remains the same even if the coil current changes. .
本発明の他の実施例を図6に示す。ここでは、外側部分315が内側部分310 より長さが長く、(接極子330が極表面にラッチされるとき)内側部分310 と接極子330の間に所定の作用エアギャップ長さLlを与える。所定のエアギ ャップ長さLlは、調整不良、磨耗、異物等によるエアギャップ長さの相対的増 加より実質的に大きいのが好ましい。従って、所定のエアギャップ長さり、があ るので、接極子とコアの調整不良によりエアギャップ長さが変化しても、電磁力 は少ししか変化しない。Another embodiment of the invention is shown in FIG. Here, the outer portion 315 is the inner portion 310 The inner portion 310 is longer in length (when the armature 330 is latched to the pole surface) and armature 330 to provide a predetermined working air gap length Ll. prescribed air conditioner The air gap length Ll is determined by the relative increase in air gap length due to poor adjustment, wear, foreign matter, etc. Preferably, it is substantially greater than the addition. Therefore, the predetermined air gap length is Therefore, even if the air gap length changes due to misalignment of the armature and core, the electromagnetic force will be changes only slightly.
本発明は、種々の用途で使うことができるが、1つの適用例を図7に示す。ここ では、本発明は制御機構の制御レバーを止め位置で「ラッチする」のに使われる 。図示するように、制御機構700は、ハウジング705とハウジング705内 に配置された制御レバー710を含む。制御レバー710は、中立と(中立の両 側の)所定の位置の間で2方向旋回運動を行う。図示するように、制御レバー7 10は2股のアーム715を形成する。電磁石接極子330がそれぞれのレバー アーム715にしっかり固定されている。センターリングバネ720が分岐に取 り付けられ、制御レバー710を中立位置に付勢する。以下に制御機構700に 関する本発明の作用を述べる。Although the present invention can be used in a variety of applications, one example application is shown in FIG. here In this case, the present invention is used to "latch" a control lever of a control mechanism in a stop position. . As shown, the control mechanism 700 includes a housing 705 and a including a control lever 710 located at. The control lever 710 has a neutral performs a two-way pivoting movement between predetermined positions (on both sides). As shown, the control lever 7 10 forms a bifurcated arm 715. Electromagnetic armature 330 connects each lever It is firmly fixed to arm 715. Centering spring 720 is attached to the branch. the control lever 710 to the neutral position. The control mechanism 700 is described below. The effects of the present invention regarding this will be described.
本発明を図7の制御機構700に関して示すが、本発明を電子、油圧、気圧型装 置等の多くの他の適用で使用できることは、当業者には明らかであろう。Although the present invention is illustrated with respect to control mechanism 700 in FIG. It will be obvious to those skilled in the art that it can be used in many other applications, such as in
本発明はさらに、製造公差、又は外側極表面の接極子との調整不良を補償する自 己調整型の取り付は態様を提供する。例えば、図8において電磁石300が取り 付はプレート800に取り付けられているように示されている。電磁石コア30 5を取り付はプレート800に取り付けるのに、ボルト805が使われている。The present invention further provides an automatic means for compensating for manufacturing tolerances or misalignment of the outer pole surface with the armature. Self-adjusting mounting provides an embodiment. For example, in FIG. The attachment is shown attached to plate 800. electromagnet core 30 5 to the plate 800, bolts 805 are used.
また、柔軟性のある材料で出来た2つのOリング810a、 bを備える。1つ の0リング810aはワッシャー815と取り付はプレート800の間に配置さ れ、他の0リング810bは取り付はプレート800と電磁石コア305の間に 配置されている。例示した構成では、電磁石の取り付けにある程度の柔軟性があ る。例えば図9に示すように、接極子330の調整はX軸に対して「傾いて」い て、しっかり取り付けられた電磁石コアとは適正に「係合」しない。しかし、こ こでは取り付けは柔軟性があり、接極子の方向に係わらず、接極子330が適正 に電磁石コア305と係合するようにすることができる。It also includes two O-rings 810a and 810b made of flexible material. one The O-ring 810a is placed between the washer 815 and the mounting plate 800. The other O-ring 810b is installed between the plate 800 and the electromagnet core 305. It is located. The example configuration allows some flexibility in mounting the electromagnets. Ru. For example, as shown in FIG. and will not properly "engage" with a firmly attached electromagnet core. However, this Here, the installation is flexible and the armature 330 is correct regardless of the armature orientation. The electromagnetic core 305 can be engaged with the electromagnetic core 305 at the same time.
他のタイプの自己調整態様を図1Oに示す。ここでは、電磁石コア305はフラ ンジ820を含み、取り付はプレート800は機械的ジヨイント825を含み、 フランジ820と噛み合って電磁石コア305を取り付はプレート800に固定 する。また、同様にこの態様により取り付けの柔軟性が増す。例えば図11に示 すように、接極子330が調整不良でも電磁石コア305と適正に係合する。Another type of self-adjustment embodiment is shown in FIG. 1O. Here, the electromagnet core 305 is the mounting plate 800 includes a mechanical joint 825; The electromagnet core 305 is attached and fixed to the plate 800 by engaging with the flange 820. do. This aspect also increases mounting flexibility. For example, as shown in Figure 11. Thus, even if the armature 330 is maladjusted, it will still properly engage the electromagnetic core 305.
他のタイプの幾何学的配置を図12に示す。ここではコア305は外側部分31 5の上に飽和領域335を形成し、飽和磁束密度を提供する。より詳しくは、コ ア305の外側コア表面上に環状溝337を形成する。飽和領域335は次の関 係の断面積Aここに、Doは飽和領域の外直径を、D、は飽和領域の内直径を表 す。Another type of geometry is shown in FIG. Here the core 305 is the outer portion 31 A saturation region 335 is formed above 5 to provide a saturation magnetic flux density. For more information, see An annular groove 337 is formed on the outer core surface of the core 305. The saturation region 335 is The cross-sectional area of A where Do is the outer diameter of the saturated region, and D is the inner diameter of the saturated region. vinegar.
この幾何学的配置により、幾つかの利点が得られる。極表面が飽和領域を作るよ うに修正されていないので、極表面の表面領域は比較的大きく、比較的高いラッ チ力を生む。その上、この構成により磁束密度と電磁力に生じる変化は僅かであ る。This geometry offers several advantages. The extreme surface creates a saturated region Since the surface area of the extreme surface is relatively large and the surface area is relatively high, Generates strength. Moreover, this configuration causes only small changes in magnetic flux density and electromagnetic force. Ru.
本発明の運転は、作業用車両の用具制御装置に使用することができる。ここでは 用具制御装置について述べているが、本発明は「ラッチ」が必要な多くの用途で 使うことができることは当業者には明らかである。 The operation of the present invention can be used in a tool control system for a work vehicle. here Although referred to as an implement control device, the present invention is useful in many applications where a "latch" is required. It will be clear to those skilled in the art that it can be used.
本発明により、車両の作業道具の「自動」制御を提供するようにしてもよい。The invention may provide for "automatic" control of a vehicle's work implements.
例えば、電磁石330は制御レバー710を所定のレバー位置で「ラッチ」し、 それは作業用具の所定の位置例えば所定のパケットの「上昇距離」又は「角度」 を表す。For example, electromagnet 330 "latches" control lever 710 in a predetermined lever position; It refers to the given position of the work implement, e.g. the "ascent distance" or "angle" of a given packet. represents.
動作において、車両のオペレーターは制御レバー710を所定の位置に旋回させ る。駆動回路725は電磁石300に励磁信号を送り、それに応じて該電磁石が 励磁され制御レバー705を所定のレバー位置に「ラッチ」する。従って、電子 油圧装置が、作業道具を所定の位置に位置させる。いったん作業用具が所定の位 置に到着すると、用具制御装置は電磁石300を消磁し、制御レバー710を電 磁石300からラッチ解除する。その後、バネ720が制御レバー710を中立 位置に付勢する。In operation, the vehicle operator pivots control lever 710 into position. Ru. The drive circuit 725 sends an excitation signal to the electromagnet 300, and the electromagnet is activated accordingly. Energized to "latch" control lever 705 into a predetermined lever position. Therefore, electronic A hydraulic system positions the work implement in position. Once the work tools are in place Upon arrival at the location, the implement controller demagnetizes the electromagnet 300 and energizes the control lever 710. Unlatch from magnet 300. The spring 720 then moves the control lever 710 to the neutral position. Force into position.
しかし、車両のオペレーターにとって、制御レバー710を所定の位置から「手 動で」ランチ解除するほうが好ましい場合もある。However, it is difficult for the vehicle operator to manually move the control lever 710 from a predetermined position. In some cases, it may be preferable to cancel lunch manually.
本発明では、バネ720のバネ力に打ち勝つのに十分な大きさだが、車両オペレ ーターがかける力により動かせる程度の大きさの所定の電磁力を与えるようにす るのが好都合である。さらに、本発明により(変動するコイル電流で駆動されて も)所定の電磁力がほぼ一定になるようになる。In the present invention, the spring 720 is large enough to overcome the spring force, but the vehicle operator A predetermined electromagnetic force that is large enough to be moved by the force applied by the motor is applied. It is convenient to Furthermore, according to the present invention (driven with varying coil current) ) The predetermined electromagnetic force becomes approximately constant.
従って、電磁力は所定の力の範囲内のままで、はぼ一定の力のレベルを与え、そ れにより、電磁力がバネの力より弱くなって意図しないときにラッチ解除される のを防止し、また電磁力がオペレーターが手動で動かせないほど大きくなるのを 防止する。この態様により電磁石に一定の電磁力が所望される多くの制御装置で 使えるようになる。Therefore, the electromagnetic force remains within a given force range, giving an approximately constant force level, and This causes the electromagnetic force to become weaker than the spring force, causing the latch to release when not intended. This prevents the electromagnetic force from becoming so large that the operator cannot move it manually. To prevent. This aspect is used in many control devices where a constant electromagnetic force is desired in the electromagnet. You will be able to use it.
