前記湿式クラッチは、例えば図２に示す如き舶用マリンギヤに使用される。該 マリンギヤは図示しないエンジンのフライホイール１の後方に各々湿式クラッチ ２、３を備えた回転軸４、５を配設し、前記クラッチ２、３の入力側を連結ギヤ ６、７で連結すると共に、出力側に設けたピニオン８、９をプロペラ１２のプロ ペラ軸１１に固定した伝達ギヤ１０に噛合わせたもので、前記湿式クラッチ２、 ３を交互に切り換えることにより船を前、後進させることができる。 該湿式クラッチ２（３）の詳細は図３に示すように、前記回転軸４（５）に固 定された前記連結ギヤ６（７）と一体の筒状部６ａ（７ａ）の内径部に内歯１３ を設け、また上記内歯１３に対応する位置において、前記回転軸４（５）に回転 自在に支持された前記ピニオン８（９）と一体の筒状部８ａ（９ａ）の外径部に 外歯１４を設けると共に、上記内歯１３と前記外歯１４とに、それぞれシンタプ レート１５及びスチールプレート１６を互いに対向するように且つ交互に、微細 な隙間を以って配設し、これらを前記内歯１３の外端に固定したエンドプレート １７及び前記筒状部６ａ内側と前記回転軸４（５）の間に密に、且つ摺動可能に 配設されたピストン１８により挟むようにしたもので、該ピストン１８の背後の 空間１９に、前記回転軸４（５）にあけたクラッチ作動油路２０を介してクラッ チ作動用油を導き、また、前記ピストン１８と前記筒状部８ａとの間に配設した ばね２１の設けられた空間２２に同じく回転軸４（５）にあけた潤滑油路２３を 介して潤滑油を導くように構成されている。 The wet clutch is used, for example, in a marine marine gear as shown in FIG. The marine gear has rotary shafts 4 and 5 respectively provided with wet clutches 2 and 3 behind a flywheel 1 of an engine (not shown), and the input sides of the clutches 2 and 3 are connected by connecting gears 6 and 7. , The output side pinions 8 and 9 are meshed with the transmission gear 10 fixed to the propeller shaft 11 of the propeller 12, and the wet clutches 2 and 3 are alternately switched to move the ship forward and backward. You can As shown in FIG. 3, the details of the wet type clutch 2 (3) are shown in an inner diameter portion of a cylindrical portion 6a (7a) that is integral with the connecting gear 6 (7) fixed to the rotating shaft 4 (5). An outer diameter of a cylindrical portion 8a (9a) integral with the pinion 8 (9) rotatably supported by the rotating shaft 4 (5) at a position corresponding to the inner tooth 13 is provided. The outer teeth 14 are provided in the portion, and the inner teeth 13 and the outer teeth 14 are respectively provided with a syntax plate 15 and a steel plate 16 so as to be opposed to each other and alternately with a minute gap, The end plate 17 fixed to the outer ends of the inner teeth 13 and the piston 18 densely and slidably disposed between the inner side of the tubular portion 6a and the rotary shaft 4 (5). In the space 19 behind the piston 18, A space for providing the clutch operating oil through a clutch operating oil passage 20 opened in the rotary shaft 4 (5) and a spring 21 arranged between the piston 18 and the tubular portion 8a. 22 is also configured to guide the lubricating oil through a lubricating oil passage 23 opened in the rotary shaft 4 (5).
【０００３】 以上のように構成された湿式クラッチ２（３）は、前記潤滑油路２３を介して 前記空間２２（及びその周辺）に調圧された潤滑油を導くと共に、後記切換バル ブによりオイルポンプから一方の湿式クラッチ、たとえば２の前記空間１９に前 記クラッチ作動油路２０を介してクラッチ作動用油が導かれる。 これによって、前記ピストン１８が図３で右に移動して、エンドプレート１７ との間で前記シンタプレート１５及びスチールプレート１６を挟んで押圧するか ら、上記シンタプレート１５及びスチールプレート１６は一体化され、前記ギヤ ６（７）の筒状部６ａ（７ａ）とピニオン８（９）の筒状部８ａ（９ａ）とが連 結されて湿式クラッチ２または３は「接」となる。 湿式クラッチ２（３）を「断」とするときは、前記切換バルブを中立位置とす ることにより、前記空間１９にあった作動用油が油路２０を経て排出されるから 、ピストン１８はばね２１により図３で左に移動して戻され、前記シンタプレー ト１５、スチールプレート１６間の押圧は開放される。従って、筒状部６ａ（７ ａ）と同８ａ（９ａ）とが連絡を断たれ、湿式クラッチ２または３は「断」とな る。 ところでこの種湿式クラッチでは、前記クラッチ作動用油として潤滑油を油圧 を上げて使用することが多いが、この場合潤滑油は回転軸４（５）にあけた潤滑 油路２３を介して前記空間２２に常時供給されており、該空間２２は前記シンタ プレート１５及びスチールプレート１６が存在する空間２４と通じているため、 前記のごとく前記空間１９にあった作動用油が油路２０を経て排出されて湿式ク ラッチ２または３は「断」となったときも、シンタプレート１５等に作用する潤 滑油圧によって湿式クラッチ２または３が半クラッチの状態となって、いわゆる 引き摺り(つれ廻り)トルクが発生し、プロペラ１２の不必要な回転をもたらす。The wet type clutch 2 (3) configured as described above guides the pressure-adjusted lubricating oil to the space 22 (and its surroundings) via the lubricating oil passage 23, and by a switching valve described later. The clutch operating oil is introduced from the oil pump to one of the wet clutches, for example, the two spaces 19 via the clutch operating oil passage 20. As a result, the piston 18 moves to the right in FIG. 3 and presses the sinter plate 15 and the steel plate 16 with the end plate 17 so that the sinter plate 15 and the steel plate 16 are integrated. Then, the cylindrical portion 6a (7a) of the gear 6 (7) and the cylindrical portion 8a (9a) of the pinion 8 (9) are connected to each other, so that the wet clutch 2 or 3 is "engaged". When the wet type clutch 2 (3) is disengaged, the operating oil in the space 19 is discharged through the oil passage 20 by setting the switching valve to the neutral position. The spring 21 moves to the left in FIG. 3 and returns it, and the pressure between the syntax plate 15 and the steel plate 16 is released. Therefore, the tubular portions 6a (7a) and 8a (9a) are disconnected from each other, and the wet clutch 2 or 3 is "disconnected". By the way, in this type of wet clutch, lubricating oil is often used by raising the hydraulic pressure as the oil for operating the clutch, but in this case, the lubricating oil passes through the lubricating oil passage 23 opened in the rotary shaft 4 (5) to the space. 22 is constantly supplied to the space 22, and the space 22 communicates with the space 24 in which the sintering plate 15 and the steel plate 16 exist. Therefore, the working oil in the space 19 is discharged through the oil passage 20 as described above. Even when the wet clutch 2 or 3 is disengaged, the wet clutch 2 or 3 becomes a half-clutch state due to the lubricating oil pressure acting on the sintering plate 15 or the like, so that a so-called drag torque is generated. Occurs, resulting in unnecessary rotation of the propeller 12.
【０００４】 本考案者等の実験によれば、この種クラッチにおいては、図５に示すように、 潤滑油量に比例して前記引き摺りトルクが増大し、一方潤滑油量にかかわらず図 ４のごとく、エンジンのほぼアイドリング回転数において引き摺りトルクが急増 する傾向があり、従ってエンジンのアイドリング回転数付近において潤滑油量を 減少させれば引き摺りトルクを低減させ得ることが判明した。According to experiments conducted by the present inventors, in this type of clutch, as shown in FIG. 5, the drag torque increases in proportion to the amount of lubricating oil, while the clutch of FIG. As described above, it has been found that the drag torque tends to increase rapidly at almost the idling speed of the engine, and therefore the drag torque can be reduced by reducing the amount of lubricating oil near the idling speed of the engine.
【０００５】 上記引き摺りトルクによる影響を避けるためには、従来、被動側、例えば前記 湿式クラッチ２、３の被動側から前記プロペラ１２に至る伝達系における摩擦力 に期待して引き摺りトルクの伝達を抑えるとか、或いは上記伝達系を強制的にロ ックしてしまう手段のほか、特開昭５１−９２９４９号公報及び実開昭５８−５ ３９２６号公報に示される技術がある。 前記特開昭公報の技術は、油槽よりの潤滑油を湿式クラッチ室に導く油路の出 口（湿式クラッチ室側）に制御弁を設け、該弁を操作レバーの作動に伴い進退す る押圧杆に連接したレリーズ部材を介して開閉するようにしたもので、上記クラ ッチの接続時には給油を行うとともに、切断時には給油を中断もしくは減少して 上記クラッチの引き摺り現象の原因となる摩擦板間の油の粘着力を直ちに減少さ せようとするものである。 また、前記実開昭公報の技術は、クラッチ板設置室に向かってクラッチ軸の外 筒面に開口した潤滑油路をクラッチ軸に摺動自在に嵌めた潤滑油路孔付き小ピス トンで覆い、上記小ピストンにより潤滑油用バルブの弁体を形成し、小ピストン 用の油圧室をクラッチ油路に接続し、クラッチ接続方向へ切換バルブを切り換え たとき、上記潤滑油路孔が潤滑油路に大開度で連通する位置へ小ピストンが移動 するようにしたものである。In order to avoid the influence of the drag torque, conventionally, the transmission of the drag torque is suppressed by expecting the frictional force in the transmission system from the driven side, for example, the driven side of the wet clutches 2 and 3 to the propeller 12. In addition to the means for forcibly locking the transmission system, there are techniques disclosed in Japanese Patent Laid-Open Nos. 51-92949 and 58-5 3926. In the technique disclosed in the above-mentioned Japanese Patent Laid-Open Publication, a control valve is provided at the outlet of the oil passage (on the side of the wet clutch chamber) that guides the lubricating oil from the oil tank to the wet clutch chamber, and the valve is pushed forward and backward as the operating lever operates. It is designed to open and close via a release member connected to the rod.When the clutch is connected, oil is supplied, and when the clutch is disconnected, oil supply is interrupted or reduced to cause the clutch drag phenomenon. It is intended to immediately reduce the adhesive strength of the oil. Further, in the technology disclosed in the above-mentioned Japanese Utility Model Publication, a lubricating oil passage opened to the outer surface of the clutch shaft toward the clutch plate installation chamber is covered with a small piston having a lubricating oil passage hole slidably fitted on the clutch shaft. When the valve body of the lubricating oil valve is formed by the small piston, the hydraulic chamber for the small piston is connected to the clutch oil passage, and the switching valve is switched in the clutch connecting direction, the lubricating oil passage hole is The small piston moves to the position where it communicates with the large opening.

しかしながら、前記特開昭公報及び実開昭公報に示されたものは、いずれも潤 滑油の制御用弁を回転力の伝達系部材内に設置したものであるから、構造が複雑 であるばかりでなく、既存の装置に簡単に装着することができないという問題点 がある。 本考案は上記問題点を解決することを課題として案出されたもので、潤滑油の 制御用弁を回転力の伝達系部材内に設置することなく、且つ既存の装置にも簡単 に装着して潤滑油量を容易に制御することができ、引き摺りトルクの発生を防止 する湿式クラッチの引き摺り防止装置を提供することを目的とする。 However, in both of the above-mentioned Japanese Patent Laid-Open Publications and Japanese Utility Model Publications, a lubricating oil control valve is installed in a rotational force transmission system member, so that the structure is not only complicated. In addition, there is a problem that it cannot be easily installed in the existing device. The present invention has been devised as a solution to the above-mentioned problems, and it is possible to easily install the lubricating oil control valve in an existing device without installing it in the rotational force transmission system member. It is an object of the present invention to provide a drag prevention device for a wet clutch that can easily control the amount of lubricating oil and prevent the generation of drag torque.

上記目的を達成するための本考案湿式クラッチの引き摺り防止装置は、ポンプ より切換バルブを介し湿式クラッチに作動用油を送り、前記バルブの中立時作動 用油を油溜へ逃がす作動油系よりバイパスして、前記クラッチを含む被潤滑個所 に潤滑用油を送る潤滑油系に、電磁調圧型潤滑油リリーフ弁を接続するとともに 、該リリーフ弁を前記切換バルブの操作と連動して該バルブの中立時に減圧し、 操作時に高圧となるよう制御せしめることを特徴とする。 In order to achieve the above object, the anti-slip device for a wet clutch of the present invention is a bypass for a hydraulic oil system that sends hydraulic oil from a pump to a wet clutch through a switching valve and lets the neutral oil of the valve escape to an oil reservoir. Then, an electromagnetic pressure-controlled lubricating oil relief valve is connected to the lubricating oil system that sends lubricating oil to the lubricated part including the clutch, and the relief valve is linked to the operation of the switching valve to neutralize the valve. The feature is that the pressure is reduced at times and the pressure is controlled to be high during operation.

上記構成の本考案湿式クラッチの引き摺り防止装置では、前記切換バルブが前 進または後進に切換えられ、且つエンジンが高速回転しているときは、前記電磁 調圧型潤滑油リリーフ弁の後記ソレノイドに通電されていないので、上記潤滑油 リリーフ弁は潤滑油圧を前記設定に従い高い値に調圧して油量を増大せしめる。 切換バルブが再び中立位置に戻され、エンジンが高速回転からアイドリング回 転となったときは、前記潤滑油リリーフ弁のソレノイドに通電されるので、上記 潤滑油リリーフ弁は潤滑油圧を前記設定の如く低い値に調圧して油量を減少せし める。 これによって、湿式クラッチ内に常時供給される潤滑油量も激減し、潤滑油が 後記シンタプレート等に作用して湿式クラッチが半クラッチの状態となることも なくなり、引き摺りトルクの発生及びこれに伴う回転軸、プロペラ等の不必要な 回転も生じない。 In the anti-wet clutch drag prevention device of the present invention having the above-described structure, when the switching valve is switched between forward and reverse, and when the engine is rotating at high speed, the solenoid described below is energized to the solenoid. Therefore, the lubricating oil relief valve regulates the lubricating oil pressure to a high value according to the above setting to increase the oil amount. When the switching valve is returned to the neutral position and the engine changes from high speed rotation to idling rotation, the solenoid of the lubricating oil relief valve is energized, so the lubricating oil relief valve sets the lubricating oil pressure to the above setting. Adjust the pressure to a lower value to reduce the oil amount. As a result, the amount of lubricating oil that is constantly supplied to the wet clutch is drastically reduced, and the lubricating oil does not act on the sintering plate, etc., described later, so that the wet clutch does not become a half-clutch state. Unnecessary rotation of the rotating shaft and propeller does not occur.

It is configured. A bypass pipe 39 is connected to the hydraulic oil system 31 in front of the accumulator 37, and a lubricating oil is supplied to a lubricated portion including the wet clutches 2 and 3 via a main relief valve 40 arranged in the pipe 39. A lubricating oil system 41 for sending the oil is constituted. Reference numeral 42 denotes an electromagnetic pressure control type lubricating oil relief valve, which is configured such that a pressure control backup piston 44 pushed up by a relief spring 43 is pressed by a pressing spring 45 stronger than the relief spring 43, and a lower end is fixed to the piston 44. The operating rod 46 is arranged so as to be in the solenoid 47. The electromagnetic pressure control type lubricating oil relief valve 42 is connected to the lubricating oil system 41 and communicates with the oil tank 32, and the solenoid 47 senses the hydraulic oil pressure for operation when the switching valve 38 is operated. Connected to a power source via a pressure switch 49 which is disposed in the pressure regulating system line 48 and which is decompressed and turned on at the neutral state of the switching valve 38, or is turned on in the neutral state of the switching valve 38. It is connected to the power supply through the switch 49 'that turns on. The lubricating oil relief valve 42 supplies the adjusted hydraulic pressure to, for example, 5 per 1 cm 2 when the hydraulic oil for operation after the switching valve 38 acts in the pressure regulating system conduit 48 when the switching valve 38 is operated. It is set to be kilograms, or, for example, 2 kilograms per square centimeter when the operating oil pressure after the switching valve 38 does not act when the switching valve 38 is in the neutral position. The main relief valve 40 in the present embodiment also has a backup piston 40a, and the hydraulic oil pressure for operation after the switching valve 38 and the accumulator 37 are connected to the piston 40a.
【００１０】 以上のように構成された本考案湿式クラッチの引き摺り防止装置では、前記切 換バルブ３８が図１の中立位置から前進または後進に切換えられ、且つエンジン が高速回転しているときは、前記圧力スイッチ４９または前記スイッチ４９’が オフ（ＯＦＦ）となっているから、電磁調圧型潤滑油リリーフ弁４２のソレノイ ド４７には通電されず、従ってバックアップピストン４４は押圧ばね４５により リリーフスプリング４３に抗して押下げられ、上記潤滑油リリーフ弁４２は潤滑 油圧を前記設定に従い高い値(例えば１平方センチメートル当り５キログラム)に 調圧して油量を増大せしめる。 切換バルブ３８が再び図１の中立位置に戻り、且つエンジンが高速回転からア イドリング回転となったときは、前記圧力スイッチ４９または前記スイッチ４９ ’がオン（ＯＮ）となって電磁調圧型潤滑油リリーフ弁４２のソレノイド４７に 通電され、これによってバックアップピストン４４は、作動杆４６を介しソレノ イド４７によって押圧ばね４５に抗して引き上げられ、前記潤滑油リリーフ弁４ ２は潤滑油圧を前記設定の如く低い値(例えば１平方センチメートル当り２キロ グラム)に調圧して油量を減少せしめる。 従って、前記回転軸４（５）にあけた潤滑油路２３を介して前記空間２２に常 時供給される潤滑油量も激減し、潤滑油が前記シンタプレート１５等に作用して 湿式クラッチ２または３が半クラッチの状態となることもなくなり、引き摺りト ルクの発生及びこれに伴う回転軸４（５）、プロペラ１２等の不必要な回転も生 じない。In the anti-wet clutch drag prevention device of the present invention constructed as described above, when the switching valve 38 is switched from the neutral position of FIG. 1 to forward or reverse, and the engine is rotating at high speed, Since the pressure switch 49 or the switch 49 'is turned off, the solenoid 47 of the electromagnetic pressure-controlled lubricating oil relief valve 42 is not energized, and therefore the backup piston 44 is pressed by the pressing spring 45. When pushed down against the pressure, the lubricating oil relief valve 42 regulates the lubricating oil pressure to a high value (for example, 5 kilograms per square centimeter) according to the above-mentioned setting to increase the oil amount. When the switching valve 38 returns to the neutral position in FIG. 1 again and the engine changes from the high speed rotation to the idling rotation, the pressure switch 49 or the switch 49 ′ is turned on (ON), and the electromagnetic pressure control type lubricating oil. The solenoid 47 of the relief valve 42 is energized, so that the backup piston 44 is pulled up against the pressing spring 45 by the solenoid 47 via the operating rod 46, and the lubricating oil relief valve 42 sets the lubricating oil pressure to the above setting. Adjust the pressure to such a low value (for example, 2 kilograms per square centimeter) to reduce the amount of oil. Therefore, the amount of lubricating oil constantly supplied to the space 22 through the lubricating oil passage 23 formed in the rotary shaft 4 (5) is also drastically reduced, and the lubricating oil acts on the sintering plate 15 and the like to wet the clutch 2 Alternatively, the clutch 3 will not be in the half-clutched state, and the drag torque will not be generated and the unnecessary rotation of the rotating shaft 4 (5), the propeller 12, etc. will not occur.

An electromagnetic pressure-controlled lubricating oil relief valve is connected to the lubricating oil system that sends lubricating oil to the lubricated location, and the relief valve is linked to the operation of the switching valve to reduce the pressure when the valve is in the neutral position and to increase the pressure when operating. Since the solenoid of the lubricating oil relief valve is energized when the switching valve is in the neutral position and the engine is idling, the backup piston of the lubricating oil relief valve described above is activated. The oil pressure of the lubricating oil is raised to a low value to drastically reduce the amount of lubricating oil that is constantly supplied into the wet clutch. Acts on Tapureto a wet clutch eliminates the Rukoto such as a half-clutch state, the rotary shaft with generation and to the drag torque, does not cause unnecessary rotation of the propeller or the like. Further, unlike the ones disclosed in the above-mentioned Japanese Patent Laid-Open Publication No. Sho and Japanese Unexamined Utility Model Publication No. Sho, the electromagnetic pressure control type lubricating oil relief valve is connected to the lubricating oil system outside the transmission system including the wet clutch, and Not only the structure is simple, but the relief valve is not only simple in structure but also easy to install in existing equipment, because the relief valve is operated so that the pressure is reduced when the valve is neutral and the pressure is controlled to be high during operation. As a result, the amount of lubricating oil can be easily controlled.
