Description

本発明は、請求項１の前段に記載の、内燃機関の弁装置の二つの作動要素を連結又は分離する方法、及び請求項７の前段に記載の、そのための装置に関する。   The invention relates to a method for connecting or separating two actuating elements of a valve device of an internal combustion engine according to the first stage of claim 1 and to an apparatus therefor according to the first stage of claim 7.

内燃機関の弁装置の二つの作動要素を連結又は分離する上述の装置は、特許文献１から知られている。その装置は、内燃機関のシリンダヘッドに取り付けられた電磁石を有し、その電機子は、二つの最終位置をとることができる。電機子は、旋回レバーに作用するロック要素を作動させる。ロック要素を作動させるために、電磁石は、連続的に励磁されなければならず、その結果、電気的エネルギを不必要に高消費する。   The above-described device for connecting or separating two actuating elements of a valve device of an internal combustion engine is known from US Pat. The device has an electromagnet attached to the cylinder head of the internal combustion engine, and the armature can take two final positions. The armature actuates a locking element that acts on the swivel lever. In order to actuate the locking element, the electromagnet must be energized continuously, resulting in an unnecessarily high consumption of electrical energy.

欧州特許出願公開第０８３３０４１Ａ１号明細書European Patent Application Publication No. 08333041A1

本発明は、作動信頼性が高く、電気的エネルギ消費量がかなり低減された状態で動作する、内燃機関の弁装置の二つの作動要素を連結又は分離する方法及び装置を提供するという目的に基づいている。   The invention is based on the object of providing a method and a device for connecting or separating two actuating elements of a valve device of an internal combustion engine that are highly reliable in operation and operate with a considerably reduced electrical energy consumption. ing.

この目的は、請求項１の特徴を有する、内燃機関の弁装置の二つの作動要素を連結又は分離する方法と、請求項７の特徴を有する、内燃機関の弁装置の二つの作動要素を連結又は分離する装置とによって達成される。   This object is achieved by a method for connecting or separating two actuating elements of a valve device of an internal combustion engine having the features of claim 1 and by connecting two actuating elements of a valve device of an internal combustion engine having the features of claim 7. Or by means of a separating device.

本発明の重要な利点は、永久磁力が、さらに電機子に作用することができることである。この結果、永久磁力の作用によって、励磁がオフに切り換わった後で、電機子は、磁石の前の励磁の結果としてとられる位置の少なくとも一つを保持し、その結果、電磁石は、連続的に励磁される必要がない。   An important advantage of the present invention is that permanent magnetism can further act on the armature. As a result, after the excitation has been switched off by the action of a permanent magnetic force, the armature holds at least one of the positions taken as a result of the previous excitation of the magnet, so that the electromagnet is continuously There is no need to be excited.

電機子は、有利には、逆極性の電磁石の新たな励磁の結果、その保持された位置を維持し、これは、短い電流パルスのみを必要とする。   The armature advantageously maintains its retained position as a result of a new excitation of the opposite polarity electromagnet, which requires only a short current pulse.

前の励磁によって磁化された電機子によって永久磁力が印加されることができることの結果、さらなる利点が生じる。これにより、低電力消費で内燃機関の弁装置の二つの作動要素を連結及び分離する簡単な構成の装置を提供することができる。   A further advantage arises as a result of the permanent magnetic force being able to be applied by the armature magnetized by the previous excitation. As a result, it is possible to provide a device having a simple configuration for connecting and separating the two operating elements of the valve device of the internal combustion engine with low power consumption.

永久磁力は、有利には、磁石回路、特に電機子内に配置された永久磁石によって印加され、これにより、長時間に亘って一つの位置で安定状態を確保することができる。   The permanent magnetic force is advantageously applied by a magnet circuit, in particular a permanent magnet arranged in the armature, so that a stable state can be ensured at one position for a long time.

この装置はまた、有利には、電機子に作用する復帰バネを有しており、この復帰バネは、電気的エネルギを使用することなく電機子を移動する。   The device also advantageously has a return spring acting on the armature, which moves the armature without using electrical energy.

少なくとも一つの位置において、永久磁力は、有利には、電磁石の励磁に応じて復帰バネの力より大きく、これにより、電機子の安定位置を確保することができる。また、少なくとも一つの位置において、永久磁力は復帰バネの力より小さく、これにより、電機子を確実に移動させることができる。   In at least one position, the permanent magnetic force is advantageously greater than the force of the return spring in response to the excitation of the electromagnet, so that a stable position of the armature can be ensured. Moreover, in at least one position, the permanent magnetic force is smaller than the force of the return spring, so that the armature can be moved reliably.

本発明のさらなる改良形態及び利点は、他の従属項及び説明から明らかになる。   Further improvements and advantages of the invention will become apparent from the other dependent claims and the description.

図面において、本発明は、例示的な実施形態を参照することにより説明される。   In the drawings, the present invention will be described with reference to exemplary embodiments.

本発明の主題は、内燃機関の弁装置の二つの作動要素２、３が連結及び分離する装置であり、これらの作動要素はガスシャトル弁１に選択的に作用する。この装置において、カム軸調節装置、カム軸、平衡装置、支持要素、又はカム従動子、例えば、作動レバー又はバケットタペットを、作動要素２、３として設けることができる。切り換え可能な作動レバー２、３を有する本発明に係る装置は、次の図面に開示されている。   The subject of the present invention is a device in which two actuating elements 2, 3 of a valve device of an internal combustion engine are connected and separated, which act selectively on the gas shuttle valve 1. In this device, a camshaft adjusting device, camshaft, balancing device, support element or cam follower, for example an actuating lever or bucket tappet, can be provided as actuating elements 2,3. A device according to the invention with switchable actuating levers 2, 3 is disclosed in the following figures.

図１は、内側レバー２及び外側レバー３を有する内燃機関の少なくとも一つのガスシャトル弁１を作動させる弁装置の部分を示す。内側レバー２は、第１端が外側レバー３に支持された軸４の回りに旋回自在であり、ロックする場合は、第２端が、内側レバー２と外側レバー２とを連結する装置の要素５上に支持される。ロックを解除する場合は、内側レバー２は、アイドル走行バネ１４に作用する。   FIG. 1 shows the part of the valve arrangement for operating at least one gas shuttle valve 1 of an internal combustion engine having an inner lever 2 and an outer lever 3. The inner lever 2 is pivotable about a shaft 4 whose first end is supported by the outer lever 3, and when locked, the second end is an element of the device that connects the inner lever 2 and the outer lever 2. 5 is supported. When releasing the lock, the inner lever 2 acts on the idle travel spring 14.

外側レバー３は、例えば、小さなストロークの少なくとも一つのカム１８が作用可能なカム摺動面６を備える二つのアーム７を有する。外側レバー３のアーム７は、大きなストロークの少なくとも一つのカム１７によって作動可能な内側レバー２を包囲する。外側レバー３は、一端が内燃機関の部品８上で少なくとも間接的に支持されており、部品８は、弁の遊びの平衡要素、内燃機関のハウジング部、又は支承点となることができる。外側レバー３は、他端がガスシャトル弁１に作用する。   The outer lever 3 has, for example, two arms 7 with cam sliding surfaces 6 on which at least one cam 18 with a small stroke can act. The arm 7 of the outer lever 3 surrounds the inner lever 2 which can be actuated by at least one cam 17 with a large stroke. One end of the outer lever 3 is at least indirectly supported on a part 8 of the internal combustion engine, which part 8 can be a balance element of valve play, a housing part of the internal combustion engine or a bearing point. The other end of the outer lever 3 acts on the gas shuttle valve 1.

従って、上記システムは二つのレバー、即ち、本発明の場合、油圧弁の遊びの平衡要素８上に支持されると共に、作動されるべきガスシャトル弁１の弁棒１ａに作用する外側レバー３と、外側レバー３に取り付けられている内側レバー２とを備える。   The system thus has two levers: an outer lever 3 which, in the case of the invention, is supported on the balance element 8 of the play of the hydraulic valve and acts on the valve stem 1a of the gas shuttle valve 1 to be actuated. And an inner lever 2 attached to the outer lever 3.

選択的に内側レバー２も用いるか外側レバー３のみを用いるかしてガスシャトル弁１を作動させ、異なる弁ストロークをもたらすことができるようにするために、要素５が設けられている。要素５は、コイル９ａ、ヨーク９ｂ、及び電機子１０から成る電磁石９によってロック方向１２及びロック解除方向１３に作動することができる。電機子１０は、要素５に動作可能なように接続されており、即ち、本例示的実施形態では、電機子１０は要素５に連結されている。さらに、バネ要素１１が要素５上でロック方向１２に作用する。その結果、要素５は、バネ要素１１及び／又は電磁石９の電機子１０によってロック方向１２に押されることができ、復帰要素として作用する電機子１０によってロック解除方向１３に押されることができる。   An element 5 is provided to enable the gas shuttle valve 1 to be operated, optionally using the inner lever 2 or the outer lever 3 alone, resulting in different valve strokes. The element 5 can be actuated in the locking direction 12 and the unlocking direction 13 by an electromagnet 9 consisting of a coil 9a, a yoke 9b and an armature 10. The armature 10 is operably connected to the element 5, i.e., in the exemplary embodiment, the armature 10 is coupled to the element 5. Furthermore, the spring element 11 acts on the element 5 in the locking direction 12. As a result, the element 5 can be pushed in the locking direction 12 by the spring element 11 and / or the armature 10 of the electromagnet 9 and can be pushed in the unlocking direction 13 by the armature 10 acting as a return element.

作動信頼性レベルが高く、電気的エネルギ消費がかなり低減された状態で動作する内燃機関の弁装置の二つの作動要素を連結及び分離する装置を提供するために、本発明は、装置が電機子１０に作用する永久磁石装置（永久磁力装置）１５を有することを提案している。本例では、永久磁石装置１５は、電機子１０の部品であり、別の方法では、この電機子１０は、非永久磁石材料で作製されており、即ち、前の励磁によって磁化された電機子１０によって永久磁力即ち長期の継続的な磁力が印加される。   In order to provide a device for connecting and disconnecting two actuating elements of a valve device of an internal combustion engine that operates with a high level of operational reliability and a significantly reduced electrical energy consumption, the present invention provides a device that is armature. It is proposed to have a permanent magnet device (permanent magnetic device) 15 acting on 10. In this example, the permanent magnet device 15 is a component of the armature 10, and in another method, the armature 10 is made of a non-permanent magnet material, that is, an armature magnetized by previous excitation. 10 applies a permanent magnetic force, ie a long-term continuous magnetic force.

図２は、ロック位置にある装置の要素５を示す。電磁石９は、電源切断設定に切り換えられ、その結果、バネ要素１１は、要素５が、好ましくは外側レバー３に設けられたストッパ１６に突き当たるまで、電機子１０を電磁石９から少なくとも部分的に抜け出るようにロック方向１２に押す。この位置は、電磁石９の励磁がなくても安定的である。なぜならば、バネ要素１１の力が、電機子１０とヨーク９ｂの間の大きな距離のために低減する永久磁石装置１５の磁力より大きいからである。その結果、内側レバー２は、外側レバー３に確実にロックするように連結され、即ち、大きなストロークのカム１７は、ガスシャトル弁１を作動させる外側レバー３に内側レバー２を介して作用し、小さなストロークのカム１８はアイドル走行を実行する。   FIG. 2 shows the element 5 of the device in the locked position. The electromagnet 9 is switched to the power-off setting, so that the spring element 11 at least partly leaves the armature 10 from the electromagnet 9 until the element 5 hits a stopper 16 provided preferably on the outer lever 3. Push in the locking direction 12 as follows. This position is stable even when the electromagnet 9 is not excited. This is because the force of the spring element 11 is greater than the magnetic force of the permanent magnet device 15 that is reduced due to the large distance between the armature 10 and the yoke 9b. As a result, the inner lever 2 is securely connected to the outer lever 3, that is, the large stroke cam 17 acts on the outer lever 3 for operating the gas shuttle valve 1 via the inner lever 2, The small stroke cam 18 performs idle running.

図３は、ロック解除位置にある装置の要素５を示す。作動要素２、３をロック解除するために、電磁石９は一時的に励磁され、その結果、電機子１０は、ヨーク９ｂによって形成された凹所１９の中に引き込まれる。その結果、電機子１０に連結された要素５は、バネ要素１１の抵抗に抗して電機子によって内側レバー２の下に引き込まれる。その結果、内側レバー２は非作動状態にされ、即ち、小さなストロークのカム１８は、ガスシャトル弁１を作動させる外側レバー３に作用すると共に、大きなストロークのカム１７が作用する内側レバー２は、単に、外側レバー３の上で揺動アイドル動作を実行するのみである。   FIG. 3 shows the element 5 of the device in the unlocked position. In order to unlock the actuating elements 2, 3, the electromagnet 9 is temporarily energized so that the armature 10 is drawn into the recess 19 formed by the yoke 9b. As a result, the element 5 connected to the armature 10 is pulled under the inner lever 2 by the armature against the resistance of the spring element 11. As a result, the inner lever 2 is deactivated, that is, the small stroke cam 18 acts on the outer lever 3 that operates the gas shuttle valve 1 and the inner lever 2 on which the large stroke cam 17 acts Only the swing idle operation is executed on the outer lever 3.

すでに上述したように、電機子１０は、電磁石９の一時的な励磁により、凹所１９の中に引き込まれる。電機子１０と凹所１９の間の小さな距離のために、永久磁石装置１５の磁力は、バネ要素１１の力より大きい。その理由のために、電機子１０はまた、電磁石９の励磁なしでこの位置に留まる。これにより、電気的エネルギの消費をかなり低減することができる。   As already described above, the armature 10 is drawn into the recess 19 by temporary excitation of the electromagnet 9. Due to the small distance between the armature 10 and the recess 19, the magnetic force of the permanent magnet device 15 is greater than the force of the spring element 11. For that reason, the armature 10 also remains in this position without excitation of the electromagnet 9. Thereby, the consumption of electrical energy can be considerably reduced.

図２に示されたロック位置をもたらすために、電磁石９は、一時的に逆極性に励磁される。   To provide the locked position shown in FIG. 2, the electromagnet 9 is temporarily energized to reverse polarity.
