Description

この発明は、例えば自動車などの車両に搭載されるエンジン、特に燃費節減、排気エミッション低減等を目的として、自動停止再始動装置、 いわゆるアイドリングストップ装置を搭載したエンジンを始動するスタータ用電磁スイッチ装置に関するものである。   The present invention relates to an engine mounted on a vehicle such as an automobile, and more particularly to an electromagnetic switch device for a starter that starts an engine equipped with an automatic stop / restart device, so-called idling stop device, for the purpose of reducing fuel consumption and exhaust emission. Is.

従来、エンジン始動用スタータが特に多く用いられているのは自動車であるが、近年、自動車の燃費節減、排気エミッション低減等の改善方法としてアイドリングストップ装置を搭載する自動車が増加している。   Conventionally, the starter for starting the engine has been particularly frequently used for automobiles. However, in recent years, automobiles equipped with an idling stop device are increasing as an improvement method for reducing fuel consumption and exhaust emission of automobiles.

自動車の運転中に於ける燃料消費節約のためのエンジンの一時停止時には、エンジンは一時停止の開始直後に再始動を要求されることもあり、再始動の際にエンジンが未だ完全に停止していないときには、エンジンにスタータモータを連結することに困難を来たし、両者の連結が互いに噛み合う歯車によってなされるような構造では、歯欠けを生ずる虞れがある。そのため従来装置として、エンジンの再始動要求により、スタータモータを回転させ始め、スタータモータに調速通電を行ってその回転速度をエンジンの回転速度に同期させて、スタータモータをエンジンに連結するものがある。（特許文献１参照）   When the engine is temporarily stopped to save fuel consumption while the car is in operation, the engine may be required to restart immediately after the start of the temporary stop, and the engine is still completely stopped at the time of restart. When it is not, it becomes difficult to connect the starter motor to the engine, and in a structure in which the two are connected by gears meshing with each other, there is a possibility of tooth missing. Therefore, as a conventional device, there is a device that starts rotating a starter motor in response to a restart request of the engine, applies a speed-regulating energization to the starter motor, synchronizes the rotation speed with the rotation speed of the engine, and connects the starter motor to the engine. is there. (See Patent Document 1)

また、他の従来装置として、エンジンの再始動要求が発生したときに、スタータへの通電を開始してピニオンを回転させ、このピニオンの回転速度が前記リングギアの回転速度と同期した時点で、前記ピニオン押し出し手段により前記ピニオンを前記リングギアに噛み込ませて前記スタータによるクランキングを開始してエンジンを再始動させるようにしたものがある。また、ピニオンの回転速度がリングギア回転速度と同期する時点を予測し、その時点に合わせてピニオンをリングギアに噛み込ませるようにピニオン押し出し手段の押し出し速度及び／ 又は押し出し開始タイミングを制御するものがある。（特許文献２参照）   Further, as another conventional device, when an engine restart request is generated, energization of the starter is started to rotate the pinion, and when the rotational speed of the pinion is synchronized with the rotational speed of the ring gear, There is one in which the pinion is engaged with the ring gear by the pinion pushing means and cranking by the starter is started to restart the engine. Also, predicts when the rotation speed of the pinion is synchronized with the rotation speed of the ring gear, and controls the extrusion speed and / or the extrusion start timing of the pinion extrusion means so that the pinion is engaged with the ring gear at that time There is. (See Patent Document 2)

また、従来のスタータ用電磁スイッチ装置では、コイルに通電することにより磁界を発生させ、プランジャを磁化させることによりそのプランジャに取付けられたフックとレバーを介してピニオンギヤを飛び出させることによりリングギヤと噛合わせる機能と、その移動を利用し、プランジャが固定接点に到達し、可動接点を介して内部接点を閉じることにより電源からモータ間への通電開閉を行なう機能を有しており、コイルへの通電という1つのプロセスで上述した２つの動作を行っている。   Further, in the conventional starter electromagnetic switch device, a magnetic field is generated by energizing the coil, and the plunger is magnetized to engage the ring gear by popping out the pinion gear via the hook and lever attached to the plunger. Using the function and its movement, the plunger reaches the fixed contact and has a function to open and close the energization from the power source to the motor by closing the internal contact via the movable contact. The above-described two operations are performed in one process.

上述した従来のスタータ用電磁スイッチ装置においては、アイドリングストップ装置による高速始動・静粛性を実現するうえで、惰性回転中のリングギヤにピニオンギヤが飛込み、当接する際にピニオンギヤとリングギヤの回転速度が同期するよう、ピニオンギヤが飛び出すよりも早くモータを回転させる必要があるという課題が生じる。   In the above-described conventional starter electromagnetic switch device, the rotational speed of the pinion gear and the ring gear synchronizes when the pinion gear jumps into and comes into contact with the ring gear during inertial rotation in order to achieve high speed start and quietness by the idling stop device. Thus, there arises a problem that the motor needs to be rotated faster than the pinion gear pops out.

また、スタータ用電磁スイッチ装置１０は、主接点５を車輌用電源装置３０へケーブルにより接続されており、更に第１の励磁コイル１２と第２の励磁コイル２０は別々のケーブルにて電子制御装置３１に接続され、キースイッチ３２を介し、車両用電源装置３０と接続されている。第１の励磁コイル１２の下流側はボディーアースへ接続され、第２の励磁コイル２０の下流側もボディーアースに接続される。   The starter electromagnetic switch device 10 has the main contact 5 connected to the vehicle power supply device 30 by a cable, and the first exciting coil 12 and the second exciting coil 20 are electronically controlled by separate cables. 31, and is connected to the vehicle power supply device 30 via the key switch 32. The downstream side of the first exciting coil 12 is connected to the body ground, and the downstream side of the second exciting coil 20 is also connected to the body ground.

次に動作について説明する。アイドリングストップにおいて、惰性回転中のリングギヤに対してピニオンギヤ４の回転速度を同期させるため、エンジン始動要求の際には、電子制御装置３１の制御により、第２の励磁コイル２０に電流が通電される。第２の励磁コイル２０への通電により、主接点５と可動接点２７が閉路されることで、車両用電源装置３０からスタータモータ１へ電力が供給され、ピニオンギヤ４の回転が開始する。そして、リングギヤの回転と、ピニオンギヤ４の回転が同期するタイミングを狙い、電子制御装置３１の制御により、第１の励磁コイル１２に電流を通電させることで、ピニオンギヤ４がリングギヤと噛合わせる。この時、第１の励磁コイル１２に電流を通電した際に第１の固定鉄心１４のフランジ部１４ａに流れる磁束３３の向きと、第２の励磁コイル２０に電流を通電した際に第１の固定鉄心１４のフランジ部１４ａに流れる磁束３４の向きとが、逆方向となり、双方に通電したときは互いに磁束を相殺するように構成されている。   Next, the operation will be described. In idling stop, in order to synchronize the rotational speed of the pinion gear 4 with the ring gear during inertial rotation, when the engine is requested to start, current is supplied to the second exciting coil 20 under the control of the electronic control unit 31. . By energizing the second exciting coil 20, the main contact 5 and the movable contact 27 are closed, whereby electric power is supplied from the vehicle power supply device 30 to the starter motor 1 and rotation of the pinion gear 4 starts. Then, aiming at the timing at which the rotation of the ring gear and the rotation of the pinion gear 4 are synchronized, the electric current is supplied to the first excitation coil 12 under the control of the electronic control device 31 so that the pinion gear 4 meshes with the ring gear. At this time, the direction of the magnetic flux 33 flowing in the flange portion 14a of the first fixed iron core 14 when a current is supplied to the first exciting coil 12, and the first direction when a current is supplied to the second exciting coil 20 are shown. The direction of the magnetic flux 34 flowing through the flange portion 14a of the fixed iron core 14 is in the opposite direction, and is configured to cancel the magnetic fluxes when both are energized.

この実施の形態１においては、第１の励磁コイル１２に電流を通電した際に第１の固定鉄心１４のフランジ部１４ａに流れる磁束３３の向きと、第２の励磁コイル２０に電流を通電した際に第１の固定鉄心１４のフランジ部１４ａに流れる磁束３４の向きとが、逆方向となるよう構成したことにより、第１の励磁コイル１２と第２の励磁コイル２０の双方に通電されても、第１の固定鉄心１４のフランジ部１４ａの磁束が飽和することがなく、吸引力を最大に発揮することができるため、第１のプランジャ１６および第２のプランジャ１８が迅速に作動し、安定した噛合い性能を得ることができる。   In the first embodiment, when a current is supplied to the first exciting coil 12, the direction of the magnetic flux 33 flowing through the flange portion 14a of the first fixed iron core 14 and the current is supplied to the second exciting coil 20. In this case, since the direction of the magnetic flux 34 flowing through the flange portion 14a of the first fixed iron core 14 is opposite, both the first exciting coil 12 and the second exciting coil 20 are energized. However, since the magnetic flux of the flange portion 14a of the first fixed iron core 14 is not saturated and the attraction force can be maximized, the first plunger 16 and the second plunger 18 operate quickly, Stable meshing performance can be obtained.
