Abstract

僅かな取付け場所しか必要としない係脱自在の油圧支持部材を提案する。このためにスライド(23)の穴(16)が油圧式遊び補償要素(11)の圧力ピストン(10)の横で内部部材(7)を通り、盲穴として作製されている。これによって従来先行技術で見られる内部部材と遊び補償要素の穴の、上下に重ねて組み込んだ構造が廃止される。同時に、スライド(23)はシリンダヘッド(5)にあるハウジング(19)に組込まれている。
【選択図】図1
A detachable hydraulic support member requiring only a small mounting space is proposed. For this purpose, the bore (16) of the slide (23) passes through the inner part (7) beside the pressure piston (10) of the hydraulic play compensation element (11) and is made as a blind bore. This eliminates the structure of the prior art in which the internal member and the hole of the play compensating element are stacked one on top of the other. At the same time, the slide (23) is integrated in the housing (19) in the cylinder head (5).

Description

【0001】
[発明の分野]
本発明は外側ハウジング、内部部材、油圧式遊び補償要素及び連結手段を有し、外側ハウジングの外周面がシリンダヘッドのソケットの中に取付けられ、かつ外側ハウジングが縦穴を有し、切断の場合は内部部材が縦穴の中で軸方向に移動可能であり、内部部材が別の穴を有し、その中に頭部を備えた圧力ピストンが遊び補償要素の構成部分として収容され、連結手段が内部部材及び外側ハウジングに半径方向に又は割線状に延びる少なくとも1個の穴と少なくとも1個の所属のスライドからなり、内部部材と外側ハウジングの相対位置で上記の穴が互いに一線に並び、連結の場合はスライドが作動手段によって外側ハウジングの穴から内部部材の穴へ所定の区間を移動させられる、内燃機関の弁操作機構のための係脱自在の支持部材に関する。
【0002】
[発明の背景]
種概念に係る支持部材はドイツ国特許公報DE4422340A1で明らかである。内部部材をカム方向に戻すためにいわゆるロストモーション(から動き)圧縮ばねが設けられ、それが全長を増加する。またスライドのための内部部材の穴は全内部部材を半径方向に貫通し、遊び補償要素の軸方向下側に配設されている。こうして上下に重ねて組込んだ不利な構造が生じる。支持部材のためのシリンダヘッドのソケットの至近区域に例えば冷却水通路又は給排気路が通っているから、比較的長い支持部材の取付け深さには限界があり、又は既存のシリンダヘッドを費用を掛けて変更しなければならない。ところがこの変更は特に給排気路の流れ条件に干渉することになるので、多くの場合不可能である。
【0003】
[発明の目的]
そこで発明の課題は、上述の欠点が簡単な手段により取り除かれた上記の種類の係脱自在の支持部材を提供することである。
【0004】
[発明の要約]
本発明に基づきこの課題は内部部材の穴が盲穴として作製され、その軸線が内部部材の別の穴と交差することによって解決される。
【0005】
こうして簡単な手段により上記の欠点が取り除かれる。遊び補償要素及びスライドのための内部部材の穴を上下に重ねて組込んだ、従来先行技術で見られる構造が回避される。こうして上記の先行技術による解決策よりも短く構成され、従って従来の構造のシリンダヘッドにたやすく取付けることができる係脱自在の支持部材が生じる。
【0006】
周囲に分布した複数個の連結手段を使用することももちろん可能であり、それによってより高い負荷能力が得られる。
【0007】
発明の好ましい実施形態によれば、例えばロッドとして作製されたスライドのための作動手段は、シリンダヘッドにあって外側ハウジングの受座に隣接するハウジングに取付けられる。同時にハウジング部片の内側端面によって、外側ハウジングに対する内側部材の簡単な回り止めを設けることが提案される。また外側ハウジングに対する内部部材の垂直ストップをこの区域に実現することもできる。この処置に基づき、別の回り止め手段や垂直ストップ手段を廃止することができる。作動手段のためのハウジングは、好都合なことに冒頭に挙げた冷却水通路、給排気路や点火プラグピット、カムシャフト軸受等と交差しないシリンダヘッド区域に配設される。
【0008】
こうしてスライドとその作動手段はほとんど支持部材の外部にあり、支持部材に対して半径方向に又は割線状に作用するだけである。スライドの斜め係合又は例えば球、つめ又はピンによる直接連結も考えられる。これらはスライドによって作動され、従ってスライドは直接的係合部材ではない。
【0009】
発明の別の好ましい実施形態によれば、スライドを電磁的又は油圧的に作動するように構成されている。例えばスライド自体の外側端面が圧油のための圧力室を画定し、又は電磁作動用の接極子板を備えたアクチュエータロッドとして形成することができる。
【0010】
最後に、電磁式又は油圧式作動手段の力に抗してスライドをリセットするための手段を同じくハウジングに取付けた構成とする。これは切換え式支持部材の小型化を目指すもう一つの対策である。
【0011】
支持部材がカムリフトによって完全にではなく部分的にだけ切断される解決策も同じく本発明の保護範囲に含まれる。スライドの穴を内部部材の様々な高さに配置することによって複数の切断段階を実現することも考えられる。
【0012】
図面に基づいて発明を詳述する。単一の図は係脱自在の支持部材の縦断面概略図を示す。
【0013】
[図の詳細な説明]
図1は係脱自在の支持部材1を開示する。支持部材1は外周面3がシリンダヘッド5のソケット4に固設された外側ハウジング2を備える。外側ハウジング2は縦穴6を有する。縦穴6の中に、外周面8を有する内部部材7が通っている。内部部材7の穴9の中に詳しく説明しない油圧式遊び補償要素11の構成部分として軸方向移動可能な圧力ピストン10が取付けられている。内部部材7の底部12と、相対する逆止弁13との間に圧油のための高圧室14がある。同時に底部12と外側ハウジング2の底部14aとの間にロストモーションばね14bが緊挿されている。また図は、圧力ピストン10が内部部材7から突出する頭部15を有することを開示する。この頭部15は、図示しない切換え可能又は切換え不能なドラグレバーのためのささえとして使用される。
【0014】
内部部材7と外側ハウジング2は各々1個の穴16、17を有する。ここに示す略図ではこれらの穴が互いに一線に並んでいる。内部部材7の穴16は盲穴として形成され、圧力ピストン10の高さにある。その軸線は内部部材7の穴9と交差する。
【0015】
これに対して外側ハウジング2の穴17は貫通穴として作られている。この穴の中にハウジング19の部分18が通っている。ハウジング部分18はその内側20が外周面8の軸方向溝21の中に達し、この軸方向溝21によって側面を取囲まれる。この構造は外側ハウジング2に対する内部部材7の回り止めとして、それとともに穴16、17の周方向位置の一致のために利用される。内側20の下側に張り出す、軸方向溝21の図示しない段差部によって穴16、17の軸方向位置の一致を実現することもできる。
【0016】
穴16、17は連結手段22の構成部分である。連結手段22の別の構成部分は、ここに概要だけ図示したスライド23である。スライド23はハウジング19の中にあり、又はハウジング部分18によって取囲まれる。ここに示す変型によれば穴16、17は互いに一線に並んでいるから、作動手段24の力によってスライド23の内側端面25を内部部材7の穴16の中に所定の区間だけ移動することができる。それによって支持部材1は接続され、ドラグレバーにより作動される給排気弁が最大行程で開放することになる。切断の場合は作動手段24又はスライド23に作用するリセット手段(図示せず)例えば圧縮ばねがスライド23を、内部部材7の穴16が開放されるまで後退させる。こうして内部部材7はカムリフトとともに外側ハウジング2に対して相対的に移動させられる。給排気弁が引き続き閉鎖され、ドラグレバーが支持部材側に旋回される。
【0017】
発明の特別の利点は、支持部材1がごく僅かな取付け場所しか必要としないことである。この場合単に盲穴として作られた内部部材7の穴16を圧力ピストン10の横に配置することによって、スライド及び油圧式遊び補償要素のための内部部材の貫通穴の従来先行技術で上下に重ねて組込んだ構造が廃止される。

[Field of the Invention]
The invention has an outer housing, an inner member, a hydraulic play compensating element and a connecting means, the outer peripheral surface of the outer housing is mounted in a socket of a cylinder head, and the outer housing has a vertical hole, in case of cutting, The inner member is axially movable in the longitudinal hole, the inner member has another hole, in which a pressure piston with a head is accommodated as a component of the play compensating element, In the case of a connection, comprising at least one hole and at least one associated slide extending radially or secant in the member and the outer housing, said holes being aligned with each other at the relative position of the inner member and the outer housing. Relates to a detachable support member for a valve operating mechanism of an internal combustion engine, wherein a slide is moved by an actuating means a predetermined section from a hole in the outer housing to a hole in the inner member. .
[0002]
[Background of the Invention]
A support element according to the concept is evident from German patent publication DE 44 22 340 A1. A so-called lost motion compression spring is provided to return the inner member to the cam direction, which increases the overall length. The bore of the inner member for the slide penetrates the entire inner member in the radial direction and is disposed axially below the play compensating element. This results in a disadvantageous structure which is assembled vertically. Due to the passage of e.g. cooling water passages or supply / exhaust passages in the immediate vicinity of the socket of the cylinder head for the support member, the mounting depth of the relatively long support member is limited, or existing cylinder heads are costly. You have to change it. However, this change is not possible in many cases, especially since it will interfere with the flow conditions of the supply and exhaust passages.
[0003]
[Object of the invention]
It is an object of the invention to provide a detachable support member of the kind described in which the above-mentioned disadvantages have been eliminated by simple means.
[0004]
[Summary of the Invention]
According to the invention, this problem is solved in that the hole in the inner member is made as a blind hole, the axis of which intersects another hole in the inner member.
[0005]
The above disadvantages are thus eliminated by simple means. The structure found in the prior art, which incorporates the holes of the play compensating element and the inner member for the slide one above the other, is avoided. This results in a releasable support member that is shorter than the prior art solution described above, and thus can be easily mounted on a cylinder head of conventional construction.
[0006]
It is of course also possible to use a plurality of connection means distributed around the circumference, whereby a higher load capacity is obtained.
[0007]
According to a preferred embodiment of the invention, the actuating means for the slide, e.g. made as a rod, is mounted on the housing located on the cylinder head and adjacent to the seat of the outer housing. At the same time, it is proposed to provide a simple detent of the inner member with respect to the outer housing by means of the inner end face of the housing piece. A vertical stop of the inner member relative to the outer housing can also be realized in this area. Based on this measure, another detent means and vertical stop means can be eliminated. The housing for the actuating means is expediently arranged in the section of the cylinder head which does not intersect the cooling water passages, supply and exhaust passages, spark plug pits, camshaft bearings, etc. mentioned at the outset.
[0008]
The slide and its actuating means are thus largely external to the support member and only act radially or secant on the support member. A diagonal engagement of the slides or a direct connection, for example by a ball, pawl or pin, is also conceivable. These are actuated by the slide, so the slide is not a direct engagement member.
[0009]
According to another preferred embodiment of the invention, the slide is configured to be operated electromagnetically or hydraulically. For example, the outer end surface of the slide itself may define a pressure chamber for pressurized oil, or may be formed as an actuator rod with an armature plate for electromagnetic actuation.
[0010]
Finally, a means for resetting the slide against the force of the electromagnetic or hydraulic actuation means is also mounted on the housing. This is another measure to reduce the size of the switchable support member.
[0011]
Solutions in which the support member is only partially but not completely cut off by the cam lift are also within the protection scope of the invention. It is also conceivable to arrange a plurality of cutting steps by arranging the holes of the slide at different heights of the inner member.
[0012]
The invention will be described in detail with reference to the drawings. The single figure shows a schematic longitudinal section of a detachable support member.
[0013]
[Detailed description of figure]
FIG. 1 discloses a detachable support member 1. The support member 1 includes an outer housing 2 having an outer peripheral surface 3 fixed to a socket 4 of a cylinder head 5. The outer housing 2 has a vertical hole 6. An internal member 7 having an outer peripheral surface 8 passes through the vertical hole 6. An axially movable pressure piston 10 is mounted in the bore 9 of the inner member 7 as a component of a hydraulic play compensating element 11 not described in detail. Between the bottom 12 of the inner member 7 and the opposite check valve 13 there is a high-pressure chamber 14 for pressure oil. At the same time, a lost motion spring 14b is inserted between the bottom 12 and the bottom 14a of the outer housing 2. The figure also discloses that the pressure piston 10 has a head 15 projecting from the inner member 7. This head 15 is used as a support for a switchable or non-switchable drag lever, not shown.
[0014]
The inner member 7 and the outer housing 2 each have one hole 16,17. In the diagram shown here, these holes are aligned with one another. The hole 16 of the inner member 7 is formed as a blind hole and is at the level of the pressure piston 10. Its axis intersects the hole 9 in the internal member 7.
[0015]
On the other hand, the hole 17 of the outer housing 2 is formed as a through hole. The part 18 of the housing 19 passes through this hole. The housing part 18 has an inner side 20 which extends into an axial groove 21 of the outer peripheral surface 8 and is surrounded on its side by this axial groove 21. This structure is used as a detent for the inner member 7 with respect to the outer housing 2, as well as for matching the circumferential position of the holes 16, 17. The axial positions of the holes 16 and 17 can also be matched by a stepped portion (not shown) of the axial groove 21 projecting below the inner side 20.
[0016]
The holes 16 and 17 are components of the connecting means 22. Another component of the coupling means 22 is a slide 23, shown here only schematically. The slide 23 is in the housing 19 or is surrounded by the housing part 18. According to the modification shown here, the holes 16 and 17 are aligned with each other, so that the inner end face 25 of the slide 23 can be moved into the hole 16 of the internal member 7 by a predetermined section by the force of the operating means 24. it can. Thereby, the support member 1 is connected, and the supply / exhaust valve operated by the drag lever is opened at the maximum stroke. In the case of cutting, a resetting means (not shown) acting on the actuating means 24 or the slide 23, for example a compression spring, causes the slide 23 to retract until the hole 16 in the internal member 7 is opened. Thus, the inner member 7 is moved relative to the outer housing 2 together with the cam lift. The supply / exhaust valve is continuously closed, and the drag lever is pivoted toward the support member.
[0017]
A particular advantage of the invention is that the support member 1 requires very little mounting space. In this case, by arranging the hole 16 of the inner member 7, which is simply made as a blind hole, next to the pressure piston 10, the prior art prior art superposition of the through holes of the inner member for the slide and hydraulic play compensating elements The built-in structure is abolished.
