Description

本発明は、内燃機関始動用のスタータに係わり、特にスタータの過熱防止に関する。   The present invention relates to a starter for starting an internal combustion engine, and more particularly to preventing overheating of the starter.

一般に、自動車エンジンの始動時には、ユーザの始動スイッチ操作により、スタータの動作を手動制御しているが、例えば、始動スイッチの戻り不良等の異常が生じた場合に、電機子コイルの絶縁破壊によりコイル間で短絡すると、電源よりスタータモータに数百アンペアの大電流が長時間連続通電され、スタータに過大な熱的負荷が加わる恐れがある。 また、何らかの原因で電磁スイッチに不具合が生じた場合には、スタータモータが無負荷状態で連続通電される恐れもある。
この様に、過大な熱的負荷が生じる異常時には、何らかの手段で電源からスタータモータを電気的に切り離すことが考えられる。 In this way, in the event of an abnormality in which an excessive thermal load occurs, it is conceivable to electrically disconnect the starter motor from the power supply by some means. 例えば、特許文献1に記載されたスタータには、ブラシリード線(ブラシピグテール)の断面積を一部分小さくすることでヒューズ機能を設けた構造が示されている。 For example, the starter described in Patent Document 1 shows a structure in which a fuse function is provided by partially reducing the cross-sectional area of ​​a brush lead wire (brush pigtail).
実開平4−64972号公報Jikkenhei 4-64972 In general, when starting an automobile engine, the starter operation is manually controlled by a user's start switch operation. For example, when an abnormality such as a return failure of the start switch occurs, the coil breaks due to dielectric breakdown of the armature coil. If a short circuit occurs, a large current of several hundred amperes is continuously supplied from the power source to the starter motor for a long time, and an excessive thermal load may be applied to the starter. In addition, when a problem occurs in the electromagnetic switch for some reason, the starter motor may be continuously energized with no load. In general, when starting an automobile engine, the starter operation is manually controlled by a user's start switch operation.

If a short circuit occurs, a large current of several hundred amperes is continuously supplied from the power source to the starter motor for a long time, and an excessive thermal load may be applied to the starter. the electromagnetic switch for some reason, the starter motor may be continuously energized with no load.
In this way, it is conceivable that the starter motor is electrically disconnected from the power source by some means at the time of an abnormality in which an excessive thermal load is generated. For example, the starter described in Patent Document 1 shows a structure in which a fuse function is provided by partially reducing the cross-sectional area of a brush lead wire (brush pigtail).

上記の特許文献1に示された公知技術では、スタータモータが長時間連続通電された時にブラシリード線を溶断させる構造であるが、そのブラシリード線が銅材によって形成されているため、溶断時の溶融温度が1100℃を超えてしまう。更に、銅の熱伝導性が良好なため、ブラシリード線が溶断しても、そのブラシリード線を介して周囲の部品に高熱が伝わり易くなる。その結果、周囲の部品が高温により損傷する可能性が考えられ、安全性の面で問題があった。   In the known technique disclosed in Patent Document 1, the brush lead wire is blown when the starter motor is energized for a long time. However, since the brush lead wire is formed of a copper material, Melting temperature exceeds 1100 ° C. Furthermore, since the thermal conductivity of copper is good, even if the brush lead wire is melted, high heat is easily transmitted to the surrounding parts via the brush lead wire. As a result, there is a possibility that surrounding parts may be damaged due to high temperature, and there is a problem in terms of safety.

また、モータの界磁に永久磁石を使用したスタータでは、図9に示す様に、ブラシリード線100が直接モータリード線110に結線(溶接)されるため、その結線部が、モータリード線110を保持しているグロメット120の近傍に配置される。この場合、特許文献1の様に、ブラシリード線100にヒューズ機能を設けると、ブラシリード線100の溶断時にグロメット120が高熱により損傷する恐れがある。   Further, in the starter using a permanent magnet for the motor field, the brush lead wire 100 is directly connected (welded) to the motor lead wire 110 as shown in FIG. It is arrange | positioned in the vicinity of the grommet 120 which hold | maintains. In this case, as in Patent Document 1, if the brush lead wire 100 is provided with a fuse function, the grommet 120 may be damaged by high heat when the brush lead wire 100 is melted.

なお、ブラシリード線やモータリード線等の様に、多くの細線を束ねて構成された線同士の溶接は、細線間の接触抵抗が大きいため、溶接が非常に困難であり、ろう付けを余儀無くされることが多い。この場合、溶接と比較して生産性が悪く、コストアップの要因となっている。
本発明は、上記事情に基づいて成されたもので、その目的は、モータ回路に通常使用時より過大な熱的負荷が生じた場合に、確実に且つ安全にモータ回路を遮断できるスタータを提供することにある。 The present invention has been made based on the above circumstances, and an object of the present invention is to provide a starter capable of reliably and safely interrupting a motor circuit when an excessive thermal load is generated in the motor circuit as compared with normal use. To do. It should be noted that welding of wires that are formed by bundling many thin wires, such as brush lead wires and motor lead wires, is very difficult because of the large contact resistance between the thin wires, and must be brazed. Often lost. In this case, productivity is poor as compared with welding, which is a cause of cost increase.

上記の構成によれば、モータ回路に通常使用時より過大な熱的負荷が生じた時に、中間部材が溶断することで、モータ回路を遮断でき、モータへの連続通電を回避できる。
また、コネクションバーの低電位側に中間部材を配置しているので、熱の影響を受けたくないグロメット(一般的にゴム製である)と中間部材との距離を比較的長く採ることが可能であり、中間部材が溶断した時に、グロメットに伝わる熱を抑制でき、高熱によるグロメットの損傷を防止できる。 In addition, since the intermediate member is placed on the low potential side of the connection bar, it is possible to take a relatively long distance between the grommet (generally made of rubber) that you do not want to be affected by heat and the intermediate member.

これに対し、本発明では、電気抵抗の大きい中間部材にヒューズ機能を持たせているので、中間部材の機械的強度が低下することはなく、モータ回路に通常使用時より過大な熱的負荷が生じた場合に、中間部材が溶断してモータ回路を確実に遮断することができる。 また、中間部材は、モータリード線及びモータ内部回路より熱伝導率が低い材料を使用して形成されるので、中間部材が溶断した時に、その溶断部位の高熱が周囲に伝わり難くなる。その結果、例えば、モータリード線を保持しているグロメットを高熱から保護することができる。   On the other hand, in the present invention, since the intermediate member having a large electric resistance is provided with a fuse function, the mechanical strength of the intermediate member does not decrease, and the motor circuit has an excessive thermal load compared with that during normal use. When this occurs, the intermediate member is melted and the motor circuit can be reliably shut off. Further, since the intermediate member is formed using a material having a lower thermal conductivity than the motor lead wire and the motor internal circuit, when the intermediate member is melted, high heat at the melted portion is hardly transmitted to the surroundings. As a result, for example, the grommet holding the motor lead wire can be protected from high heat.

A portion 34e is provided.

更に、中間プレート34の形状について図2を参照しながら詳述する。

Further, the shape of the intermediate plate 34 will be described in detail with reference to FIG.
The intermediate plate 34 has a shape that can be called a convex shape or a substantially triangular shape having three convex portions 34a, 34b, and 34c. The motor lead wire 32 is connected to one convex portion 34a, and the remaining two convex portions 34b, The brush lead wire 33 is connected to 34c. The notch 34d has two corners on both sides where the central protrusion 34a and the left and right protrusions 34b, 34c intersect at a substantially right angle, and the corner on the opposite side of the central protrusion 34a. Are formed in a total of four places, two places facing each other. The intermediate plate 34 has a shape that can be called a convex shape or a substantially triangular shape having three convex portions 34a, 34b, and 34c. The motor lead wire 32 is connected to one convex portion 34a, and the remaining two convex portions 34b , The brush lead wire 33 is connected to 34c.

A small cross-sectional area 34e having a smaller cross-sectional area is provided between the central convex portion 34a and the left convex portion 34b in the drawing and between the central convex portion 34a and the right convex portion 34c in the drawing.

次に、スタータ1の作動を説明する。
始動スイッチ25の閉操作により、電磁スイッチ5の励磁コイル5aが通電されてプランジャ5bが吸引されると、シフトレバー4を介してピニオン移動体が出力軸3上を反モータ方向へ押し出され、ピニオンギヤ23がエンジンのリングギヤ37(図3参照)に当接して停止する。

一方、プランジャ5bの移動により接点手段Aが閉じると、電機子8が通電されて回転し、その電機子8の回転が減速装置で減速されて出力軸3に伝達される。 On the other hand, when the contact means A is closed due to the movement of the plunger 5b, the armature 8 is energized and rotated, and the rotation of the armature 8 is decelerated by the speed reducing device and transmitted to the output shaft 3. Next, the operation of the starter 1 will be described. Next, the operation of the starter 1 will be described.
When the excitation coil 5a of the electromagnetic switch 5 is energized and the plunger 5b is attracted by closing the start switch 25, the pinion moving body is pushed out on the output shaft 3 in the counter-motor direction via the shift lever 4, and the pinion gear 23 stops in contact with the ring gear 37 (see FIG. 3) of the engine. When the excitation coil 5a of the electromagnetic switch 5 is energized and the plunger 5b is attracted by closing the start switch 25, the pinion moving body is pushed out on the output shaft 3 in the counter-motor direction via the shift lever 4, and the pinion gear 23 stops in contact with the ring gear 37 (see FIG. 3) of the engine.
On the other hand, when the contact means A is closed by the movement of the plunger 5b, the armature 8 is energized and rotated, and the rotation of the armature 8 is decelerated by the reduction gear and transmitted to the output shaft 3. On the other hand, when the contact means A is closed by the movement of the plunger 5b, the armature 8 is energized and rotated, and the rotation of the armature 8 is decelerated by the reduction gear and transmitted to the output shaft 3.

出力軸3が回転すると、出力軸3の回転が一方向クラッチ22を介してピニオンギヤ23に伝達され、ピニオンギヤ23がリングギヤ37に噛み合い可能な位置まで回転してリングギヤ37に噛み合うと、ピニオンギヤ23からリングギヤ37に回転力が伝達されてエンジンをクランキングさせる。
エンジン始動後、始動スイッチ25が開操作されると、励磁コイル5aへの通電が停止して磁力が消滅するため、リターンスプリング5cの反力でプランジャ5bが押し戻される。 When the start switch 25 is opened after the engine is started, the energization of the exciting coil 5a is stopped and the magnetic force is extinguished, so that the plunger 5b is pushed back by the reaction force of the return spring 5c. このプランジャ5bの移動により、接点手段Aが開いてモータ2への通電が停止されると共に、シフトレバー4を介してピニオン移動体が出力軸3上を反リングギヤ方向へ後退して、図3に示す静止位置に停止する。 By the movement of the plunger 5b, the contact means A is opened to stop the energization of the motor 2, and the pinion moving body is retracted on the output shaft 3 in the direction of the anti-ring gear via the shift lever 4, as shown in FIG. Stop at the indicated stationary position. When the output shaft 3 rotates, the rotation of the output shaft 3 is transmitted to the pinion gear 23 via the one-way clutch 22. Rotational force is transmitted to 37 to crank the engine. When the output shaft 3 rotates, the rotation of the output shaft 3 is transmitted to the pinion gear 23 via the one-way clutch 22. Rotational force is transmitted to 37 to crank the engine.
When the start switch 25 is opened after the engine is started, the energization to the exciting coil 5a is stopped and the magnetic force disappears, so that the plunger 5b is pushed back by the reaction force of the return spring 5c. By this movement of the plunger 5b, the contact means A is opened and the energization to the motor 2 is stopped, and the pinion moving body moves backward on the output shaft 3 in the anti-ring gear direction via the shift lever 4, so that FIG. Stop at the indicated rest position. When the start switch 25 is opened after the engine is started, the energization to the exciting coil 5a is stopped and the magnetic force disappears, so that the plunger 5b is pushed back by the reaction force of the return spring 5c. By this movement of the plunger 5b, the contact means A is opened and the energization to the motor 2 is stopped, and the pinion moving body moves backward on the output shaft 3 in the anti-ring gear direction via the shift lever 4, so that FIG. Stop at the indicated rest position.

上記の作動において、例えば、始動スイッチ25の戻り不良が生じた場合、あるいは何らかの原因によりモータ2が無負荷状態で連続通電された場合等に、電機子コイル8bに絶縁破壊が生じてコイル間が短絡すると、バッテリ26からモータ2に数百アンペアの大電流が連続通電されることにより、モータ回路に通常使用時より過大な熱的負荷が加わる。この時、中間プレート34の温度が所定温度まで上昇すると、中間プレート34が小断面積部34eにて溶断するため、モータ回路が遮断されて、モータ2への連続通電が回避される。   In the above operation, for example, when the return failure of the start switch 25 occurs, or when the motor 2 is continuously energized without load for some reason, the armature coil 8b breaks down and the space between the coils is reduced. When short-circuited, a large current of several hundred amperes is continuously energized from the battery 26 to the motor 2, so that an excessive thermal load is applied to the motor circuit as compared with the normal use. At this time, when the temperature of the intermediate plate 34 rises to a predetermined temperature, the intermediate plate 34 is fused at the small cross-sectional area 34e, so that the motor circuit is shut off and continuous energization to the motor 2 is avoided.

(実施例1の効果)
本実施例のスタータ1は、銅と比較して電気抵抗が大きい鉄製の中間プレート34にヒューズ機能を持たせているので、モータ回路に通常使用時より過大な熱的負荷が生じた時に、銅線を束ねて構成されるモータリード線32及びブラシリード線33よりも早く且つ確実に中間プレート34を溶断させることができる。
また、鉄の熱伝導率が銅の約1/5と小さいため、中間プレート34が溶断した時に、その中間プレート34に接続されているモータリード線32及びブラシリード線33への熱伝導を抑えることができ、モータリード線32を保持しているグロメット35を高熱から保護することができる。

That is, the position where the intermediate plate 34 is arranged can be arbitrarily changed according to the position where the connection bar 40 is divided into the first bar member 40a and the second bar member 40b. As a result, the degree of freedom of the location where the intermediate plate 34 is arranged increases, so that the size and shape of the intermediate plate 34 are not greatly limited due to space constraints, and are appropriately sized as the intermediate plate 34 having a fuse function. And the shape can be selected.
