本考案は、同軸的に支持された両回転部材間に介装されてこれら両部材間のト ルク伝達を行う駆動力伝達装置に関する。 The present invention relates to a driving force transmission device that is interposed between two rotating members that are coaxially supported and that transmits torque between these two members.

かかる駆動力伝達装置は、互いに同軸的に支持された両回転部材間に介装され てこれら両部材の相対回転時これら両部材を互いにトルク伝達可能に連結するも ので、従動側回転部材を駆動させる連結機構として使用されるものと、これら両 部材間の回転差を制限させる差動制限機構として使用されるもの等に大別される 。前者の連結機構は主としてリアルタイム式の四輪駆動車における一方の動力伝 達系路に介装され、また後者の差動制限機構は主として車両における各ディファ レンシャルに介装される。 Such a driving force transmitting device is interposed between both rotating members which are coaxially supported with each other, and when both these members rotate relative to each other, these two members are coupled so that torque can be transmitted to each other, so that the driven side rotating member is driven. It is roughly divided into those used as a connecting mechanism for controlling the rotation and those used as a differential limiting mechanism for limiting the rotation difference between these two members. The former coupling mechanism is mainly installed in one power transmission path in a real-time four-wheel drive vehicle, and the latter differential limiting mechanism is mainly installed in each differential in the vehicle.
【０００３】 しかして、従来の駆動力伝達装置としては特開昭６３−２４０４２９号公報に 示されているように、同軸的かつ相対回転可能に位置する内外両回転部材間に配 設され、これら両回転部材の相対回転により作動して両回転部材をトルク伝達可 能に連結する摩擦係合力を発生させるとともに付与される軸方向の押圧力に応じ て前記摩擦係合力を増減させる摩擦クラッチ、および両回転部材の相対回転に応 じた軸方向の押圧力を発生させて同押圧力を前記摩擦クラッチに付与する押圧力 発生手段を備え、同押圧力発生手段を、前記両回転部材間に液密的に軸方向へ摺 動可能かつ外側回転部材に一体回転可能に組付けられて前記摩擦クラッチの一側 に対向する作動ピストンと、前記外側回転部材と前記作動ピストン間に形成され 軸方向に所定間隔を有して粘性流体が封入される流体室と、同流体室にて前記内 側回転部材に一体回転可能に組付けられて回転時前記流体室内に流体圧を発生さ せるロータとにより構成してなる駆動力伝達装置がある。However, as disclosed in Japanese Patent Application Laid-Open No. 63-240429, a conventional driving force transmission device is arranged between both inner and outer rotating members that are coaxially and relatively rotatable. A friction clutch that operates by relative rotation of both rotating members to generate a frictional engaging force that connects the two rotating members so that torque can be transmitted, and that increases or decreases the frictional engaging force according to an axial pressing force applied, A pressing force generating means for generating an axial pressing force corresponding to the relative rotation of both rotating members and applying the pressing force to the friction clutch is provided, and the pressing force generating means is provided between the rotating members. An operating piston that is tightly slidable in the axial direction and is integrally rotatably mounted on the outer rotating member and faces one side of the friction clutch; and a shaft formed between the outer rotating member and the operating piston. Fluid chamber in which a viscous fluid is sealed at a predetermined interval in the direction, and a rotor that is integrally rotatably assembled to the inner rotating member in the fluid chamber and generates a fluid pressure in the fluid chamber during rotation. There is a driving force transmission device configured by.
【０００４】 この種形式の駆動力伝達装置においては、両回転部材間に相対回転が生じると 押圧力発生手段に差動回転数に応じた圧力が発生する。この圧力は摩擦クラッチ を押圧して同クラッチに両回転部材をトルク伝達可能に連結する摩擦係合力を発 生させる。かかる摩擦係合力は差動回転数に比例し、両回転部材間では差動回転 数に比例したトルクが一方から他方へ伝達される。 従って、当該駆動力伝達装 置は四輪駆動車の一方の動力伝達系路における駆動側回転部材と従動側回転部材 との連結機構として機能するとともに、駆動側および従動側回転部材間、両駆動 側回転部材間または両従動側回転部材間の差動制限機構としても機能する。In this type of driving force transmission device, when relative rotation occurs between both rotary members, pressure corresponding to the differential rotation speed is generated in the pressing force generation means. This pressure presses the friction clutch to generate a frictional engagement force that couples both rotary members to the same clutch so that torque can be transmitted. Such frictional engagement force is proportional to the differential rotation speed, and torque proportional to the differential rotation speed is transmitted between the two rotary members from one to the other. Therefore, the drive force transmission device functions as a connecting mechanism between the drive-side rotating member and the driven-side rotating member in one power transmission system path of the four-wheel drive vehicle, and also between the drive-side and driven-side rotating members. It also functions as a differential limiting mechanism between the side rotating members or between both driven side rotating members.

ところで、当該駆動力伝達装置を左右輪間の差動制限機構として採用した車両 において左右のいずれかの車輪が溝等に脱輪した場合には、左右の車輪の回転差 が非常に大きくなって押圧力発生手段で発生する押圧力が極めて高くなり、この 結果作動ピストンの摩擦クラッチ側への押圧力が大きくなりすぎ、摩擦クラッチ を焼損して同摩擦クラッチのその後の機能を著しく低下させるおそれがある。従 って、本考案の目的はかかる問題に対処することにある。 By the way, in a vehicle that employs the drive force transmission device as a differential limiting mechanism between the left and right wheels, if one of the left and right wheels slips into a groove or the like, the difference in rotation between the left and right wheels becomes extremely large. The pressing force generated by the pressing force generation means becomes extremely high, and as a result, the pressing force of the working piston on the friction clutch side becomes too large, which may burn the friction clutch and significantly deteriorate the subsequent function of the friction clutch. is there. Therefore, the purpose of the present invention is to address such problems.

かかる構成の駆動力伝達装置においては、車両の左右輪のいずれか一方が溝等 に脱輪してこれら両輪間に大きな回転差が生じて押圧力発生手段に大きな押圧力 が発生しても、作動ピストンは外側回転部材間に設けられた規制部材により摩擦 クラッチ側への所定以上の摺動を規制される。従って、作動ピストンは摩擦クラ ッチに対して設定された所定の押圧力以上では押圧することはなく、摩擦クラッ チを焼損してその後の機能を著しく低下させるおそれはない。 In the driving force transmission device having such a configuration, even if one of the left and right wheels of the vehicle is derailed in a groove or the like and a large rotational difference occurs between these two wheels, a large pressing force is generated in the pressing force generating means. The actuating piston is restricted from sliding more than a predetermined amount toward the friction clutch by a restricting member provided between the outer rotating members. Therefore, the working piston does not press beyond the predetermined pressing force set against the friction clutch, and there is no risk of burning the friction clutch and significantly reducing the function thereafter.

Each clutch plate 16a has an outer peripheral spline portion fitted to a spline portion 11c provided on the inner peripheral surface of the outer case 11, and is assembled to the case 11 so as to be integrally rotatable and movable in the axial direction. Each clutch disc 16b has an inner spline portion fitted to the outer spline portion 12c of the inner shaft 12 and is located between the clutch plates 16a, and is assembled to the shaft 12 so as to be integrally rotatable and axially movable. Has been. A predetermined amount of clutch oil and gas is sealed in the storage chambers of the clutch plate 16a and the clutch disc 16b.
【００１２】 押圧力発生手段１０ａを構成する作動ピストン１３はアウタケース１１の筒部 １１ａの他端側内周に液密的に一体回転可能かつ軸方向へ摺動可能に、またイン ナシャフト１２に対してはその外周に液密的に回転可能かつ軸方向へ摺動可能に それぞれ組付けられている。ロータ１４は図１および図２に示すように、環状ボ ス部１４ａの外周の互に１８０°離れた部位にて半径方向へ延びる２枚のベーン 部１４ｂを備え、環状ボス部１４ａにてインナシャフト１２の筒部１２ａ外周に 嵌合され、同シャフト１２に対して一体回転可能に組付けられている。かかるロ ータ１４はエンドカバー１５の一側に設けた環状凹所１５の深さと略同じ厚みに 形成されていて、環状凹所１５ａ内に嵌合している。The working piston 13 constituting the pressing force generating means 10 a is liquid-tightly integrally rotatable with the inner circumference of the other end side of the cylindrical portion 11 a of the outer case 11 and slidable in the axial direction. On the other hand, they are mounted on the outer periphery thereof in a liquid-tight manner so as to be rotatable and slidable in the axial direction. As shown in FIGS. 1 and 2, the rotor 14 is provided with two vane portions 14b extending in the radial direction at positions 180 ° apart from each other on the outer circumference of the annular boss portion 14a. The shaft 12 is fitted on the outer circumference of the cylindrical portion 12a and is integrally rotatably assembled to the shaft 12. The rotor 14 is formed to have a thickness approximately the same as the depth of the annular recess 15 provided on one side of the end cover 15, and is fitted in the annular recess 15a.

It is worn and liquid-tight. The end cover 15 is axially adjusted in position and fixed to the outer case 11 by caulking means. One side of the end cover 15 abuts one side of the working piston 13, and an annular recess 15a is formed on the one side. The one side surface of the working piston 13 forms a fluid chamber in which the rotor 14 is located. A highly viscous fluid such as silicone oil is enclosed in this fluid chamber, and the rotor 14 makes its outer periphery of the vane portion 14b liquid-tightly contact with the inner periphery of the annular recess 15a so that the fluid chamber has two retention chambers. It is divided into R.
【００１４】 しかして、作動ピストン１３は摩擦クラッチ１０ｂ側に環状の突起部１３ａを 備えていて、同突起部１３ａの先端部にはアウタケース１１のスプライン部１１ ｃに嵌合するスプライン部１３ｂとアウタケース１１のスプライン部１１ｃの端 面に対抗するストッパ面１３ｃとが形成されている。スプライン部１１ｃの端面 とストッパ面１３ｃ間の間隔は下記のごとく設定されている。すなわち、作動ピ ストン１３が摩擦クラッチ１０ｂ側へ摺動して同摩擦クラッチ１０ｂを押圧する 際、同摩擦クラッチ１０ｂが焼損を生じない最大押圧力が得られる摺動量になる ように、上記間隔Ｌが設定されている。Therefore, the working piston 13 has an annular protrusion 13a on the side of the friction clutch 10b, and the tip of the protrusion 13a has a spline portion 13b fitted to the spline portion 11c of the outer case 11. A stopper surface 13c that opposes the end surface of the spline portion 11c of the outer case 11 is formed. The distance between the end surface of the spline portion 11c and the stopper surface 13c is set as follows. That is, when the operating piston 13 slides toward the friction clutch 10b and presses the friction clutch 10b, the distance L is adjusted so that the friction clutch 10b has a sliding amount that provides a maximum pressing force that does not cause burnout. Is set.
【００１５】 かかる構成の駆動力伝達装置１０においては、左右の各前輪間に相対回転が生 じるとトルク伝達がなされる。すなわち、これら両シャフト２１，２２に相対回 転が生じると、第１アクスルシャフト２１に一体回転可能に組付けられているア ウタケース１１、作動ピストン１３およびエンドカバー１５と、第２アクスルシ ャフト２２に一体回転可能に組付けられているインナシャフト１２およびロータ １４との間に相対回転が生じる。In the driving force transmission device 10 having such a configuration, torque is transmitted when relative rotation occurs between the left and right front wheels. That is, when the two shafts 21 and 22 rotate relative to each other, the outer casing 11, the operating piston 13, the end cover 15 and the second axle shaft 22 which are integrally rotatably mounted on the first axle shaft 21 are installed. Relative rotation occurs between the inner shaft 12 and the rotor 14 that are integrally rotatable.
【００１６】 従って、押圧力発生手段１０ａの流体室内においては、滞留室Ｒ内の粘性流体 が相対回転数に比例した速度にて強制的に流動させられ、周方向に順次相対移行 する滞留室Ｒ内では流動抵抗に起因してベーン部１４ｂの下流側端から次のベー ン部１４ｂの上流側端に向って漸次増圧される圧力分布が発生する。この圧力分 布の増圧部分は差動回転数に比例して増大するもので、作動ピストン１３を軸方 向へ押圧する。この結果、作動ピストン１３は摩擦クラッチ１０ｂを押圧し、各 クラッチプレート１６ａとクラッチディスク１６ｂをクラッチオイルを介して摩 擦係合させる。これにより、摩擦クラッチ１０ｂにおいては差動回転数に比例し たトルクがアウタケース１１とインナシャフト１２間に伝達され、左右の前輪間 の差動が制限される。Therefore, in the fluid chamber of the pressing force generating means 10a, the viscous fluid in the retention chamber R is forcibly flown at a speed proportional to the relative rotation speed, and the retention chamber R sequentially moves relative to the circumferential direction. Due to the flow resistance, a pressure distribution in which the pressure is gradually increased from the downstream end of the vane portion 14b toward the upstream end of the next vane portion 14b is generated therein. The pressure-increased portion of this pressure distribution increases in proportion to the differential rotation speed and presses the working piston 13 in the axial direction. As a result, the working piston 13 presses the friction clutch 10b to bring the respective clutch plates 16a and the clutch discs 16b into frictional engagement via the clutch oil. As a result, in the friction clutch 10b, torque proportional to the differential rotation speed is transmitted between the outer case 11 and the inner shaft 12, and the differential between the left and right front wheels is limited.
【００１７】 ところで、当該駆動力伝達装置１０においては、車両の左右輪のいずれか一方 が溝等に脱輪してこれら両輪間に大きな回転差が生じて押圧力発生手段１０ａに 大きな流体圧が発生しても、作動ピストン１３はアウタケース１１との間に設け られたスプライン部１１ｃの端面と作動ピストン１３のストッパ面１３ｃとによ り、摩擦クラッチ１０ｂ側への所定以上の摺動を規制される。従って、作動ピス トン１３は摩擦クラッチ１０ｂに対して設定された所定の押圧力以上では押圧す ることはなく、摩擦クラッチ１０ｂを焼損してその後の機能を著しく低下させる おそれはない。By the way, in the driving force transmission device 10, one of the left and right wheels of the vehicle is disengaged from a groove or the like, and a large rotation difference is generated between these wheels, so that a large fluid pressure is applied to the pressing force generating means 10a. Even if it occurs, the working piston 13 is restricted from sliding more than a predetermined amount to the friction clutch 10b side by the end surface of the spline portion 11c provided between the outer case 11 and the stopper surface 13c of the working piston 13. To be done. Therefore, the operating piston 13 does not press beyond the predetermined pressing force set for the friction clutch 10b, and there is no fear that the friction clutch 10b will be burned and the subsequent function will be significantly deteriorated.

In this case, the friction clutch in the high differential state between the front and rear wheels can be used. Burnout can be prevented.
