Description

本発明は、オイル受渡し構造に関する。 The present invention relates to an oil delivery structure.

たとえば、エンジンの動力により走行するコンベンショナルな車両には、変速機が搭載されている。エンジンの動力は、変速機のインプット軸に入力されて、変速機内で変速され、変速機のアウトプット軸からデファレンシャルギヤなどを介して左右の駆動輪に伝達される。 For example, a conventional vehicle that runs on engine power is equipped with a transmission. The power from the engine is input to the input shaft of the transmission, the speed is changed within the transmission, and the power is transmitted from the output shaft of the transmission to the left and right drive wheels via a differential gear or the like.

特開２０１３－１１３３０４号公報Japanese Patent Application Publication No. 2013-113304

変速機には、クラッチやベアリングなど、回転要素間の差回転を吸収しなければならない部材が多く使用されている。それらの各部材には、差回転の吸収による摩耗や焼き付きなどを防止するために、潤滑のためのオイル（潤滑油）を供給する必要がある。 Transmissions use many components, such as clutches and bearings, that must absorb differential rotation between rotating elements. It is necessary to supply each of these members with oil for lubrication (lubricating oil) in order to prevent wear and seizure due to absorption of differential rotation.

そのため、変速機では、別部材の油路間でオイルの受け渡しが生じる設計を余儀なくされる場合がある。図４には、その場合の設計の一例が示されている。図４に示される設計では、一方の部材９１の側面に開口９２が形成され、他方の部材９３の側面に開口９４が形成される。一方の部材９１に形成されている油路９５は、開口９２と連通して、開口９２で開放されている。他方の部材９３に形成されている油路９６は、開口９４と連通して、開口９４で開放されている。そして、一方の開口９２と他方の開口９４とが互いに突き合わされて、一方の部材９１と他方の部材９３との間に、開口９２，９４の周囲を取り囲むように円環状のガスケット９７が介在される。これにより、一方の部材９１の油路９５から他方の部材９３の油路９６にオイルを漏らさずに受け渡すことが可能となる。 Therefore, in a transmission, it is sometimes necessary to design a transmission in which oil is delivered between oil passages of separate members. FIG. 4 shows an example of a design in that case. In the design shown in FIG. 4, an opening 92 is formed in the side of one member 91 and an opening 94 is formed in the side of the other member 93. An oil passage 95 formed in one member 91 communicates with an opening 92 and is open at the opening 92 . An oil passage 96 formed in the other member 93 communicates with the opening 94 and is open at the opening 94 . One opening 92 and the other opening 94 are butted against each other, and an annular gasket 97 is interposed between one member 91 and the other member 93 so as to surround the openings 92 and 94. Ru. This allows oil to be transferred from the oil passage 95 of one member 91 to the oil passage 96 of the other member 93 without leaking.

しかしながら、オイルの漏れを防止するためのガスケット９７などのシール部材が必要となり、コストアップにつながる。 However, a sealing member such as a gasket 97 is required to prevent oil leakage, leading to an increase in cost.

本発明の目的は、シール部材を用いずに、互いの間に隙が生じる第１部材と第２部材との間で、第１部材の第１油路から第２部材の第２油路にオイルを良好に受け渡すことができる、オイル受渡し構造を提供することである。 An object of the present invention is to connect a first oil passage of a first member to a second oil passage of a second member between a first member and a second member with a gap between them without using a seal member. To provide an oil delivery structure capable of transferring oil well.

前記の目的を達成するため、本発明に係るオイル受渡し構造は、互いの間に隙が生じる第１部材と第２部材との間で、第１部材の第１油路から第２部材の第２油路にオイルを受け渡す構造であって、第１油路が第１方向に延びており、第１部材には、第１油路から流れてくるオイルを第１方向と交差する第２方向に放出する放出口が形成され、第２部材には、第２油路と連通し、放出口から放出されるオイルを受け入れる受入口が形成されている。 In order to achieve the above object, the oil delivery structure according to the present invention provides an oil transfer structure in which a gap is created between the first member and the second member, from the first oil passage of the first member to the oil passage of the second member. It has a structure in which oil is delivered to two oil passages, the first oil passage extends in a first direction, and the first member has a second oil passage that passes oil flowing from the first oil passage, and a second oil passage that intersects with the first direction. A discharge port that discharges oil in the direction is formed, and a receiving port that communicates with the second oil passage and receives oil discharged from the discharge port is formed in the second member.

この構成によれば、第１部材では、第１油路から放出口にオイルが流入し、そのオイルが放出口から第２方向に放出される。第２部材には、第１部材の放出口から第２方向に放出されるオイルを受け入れる受入口が形成されている。受入口は、第２油路と連通している。そのため、第１部材の放出口から放出されるオイルが第２部材の受入口に受け入れられると、受入口から第２油路にオイルが流れ込み、そのオイルが第２油路を流れる。 According to this configuration, in the first member, oil flows into the discharge port from the first oil passage, and the oil is discharged from the discharge port in the second direction. The second member is formed with a receiving port for receiving oil discharged in the second direction from the discharge port of the first member. The receiving port communicates with the second oil passage. Therefore, when the oil released from the discharge port of the first member is received by the reception port of the second member, the oil flows from the reception port into the second oil passage, and the oil flows through the second oil passage.

よって、シール部材を用いずに、互いの間に隙が生じる第１部材と第２部材との間で、第１部材の第１油路から第２部材の第２油路にオイルを良好に受け渡すことができる。 Therefore, without using a sealing member, it is possible to properly flow oil from the first oil passage of the first member to the second oil passage of the second member between the first member and the second member where a gap is created between them. It can be handed over.

第１部材には、第１油路と放出口との間に、第１油路から放出口に流れるオイルの流量を制限する絞りが形成されていてもよい。 A throttle may be formed in the first member between the first oil passage and the discharge port to limit the flow rate of oil flowing from the first oil passage to the discharge port.

この構成により、放出口から放出されるオイルの流速を高めることができ、放出口から放出されるオイルを受入口に良好に到達させることができる。その結果、第１部材と第２部材との間からオイルが漏れることを良好に抑制することができる。また、第１油路から第２油路に受け渡されるオイルの量が低減するので、第２油路から供給されるオイルで潤滑される部材の回転抵抗などを下げることができる。その結果、このオイル受渡し構造が車両の変速機などに適用される場合には、車両の燃費の向上を期待できる。さらには、第１油路から第２油路に受け渡されるオイルの低減分、第１油路から潤滑が必要な他の部材にオイルを供給することができる。 With this configuration, the flow rate of the oil discharged from the discharge port can be increased, and the oil discharged from the discharge port can be made to reach the receiving port in a good manner. As a result, leakage of oil from between the first member and the second member can be effectively suppressed. Furthermore, since the amount of oil transferred from the first oil passage to the second oil passage is reduced, it is possible to reduce rotational resistance of members lubricated with oil supplied from the second oil passage. As a result, when this oil delivery structure is applied to a vehicle transmission, etc., it can be expected that the fuel efficiency of the vehicle will be improved. Furthermore, oil can be supplied from the first oil passage to other members that require lubrication by the amount of oil transferred from the first oil passage to the second oil passage.

第２部材には、受入口の周縁部の一部から第１部材側に第１部材と第２方向にオーバラップする位置まで延出する延出部が形成されていてもよい。 The second member may have an extending portion extending from a portion of the peripheral edge of the receiving port toward the first member to a position overlapping the first member in the second direction.

この構成では、放出口以外から飛散してくるオイルの飛沫が受入口に受け入れられることを抑制でき、オイルのコンタミネーションを抑制することができる。 With this configuration, it is possible to suppress oil droplets that are scattered from sources other than the discharge port from being received in the receiving port, and it is possible to suppress oil contamination.

本発明によれば、シール部材を用いずに、互いの間に隙が生じる第１部材と第２部材との間で、第１部材の第１油路から第２部材の第２油路にオイルを良好に受け渡すことができる According to the present invention, the first oil passage of the first member is connected to the second oil passage of the second member between the first member and the second member with a gap between them without using a seal member. Can transfer oil well

＜オイル受渡し構造＞
図１は、本発明の一実施形態に係るオイル受渡し構造が適用される変速ユニット１の一部を示す図である。 <Oil delivery structure>
FIG. 1 is a diagram showing a part of a transmission unit 1 to which an oil delivery structure according to an embodiment of the present invention is applied.

変速ユニット１は、車両に搭載されて、走行用の駆動源としてのエンジン２（Ｅ／Ｇ）２が発生する動力を変速するユニットである。変速ユニット１は、プライマリプーリとセカンダリプーリとに無端状のベルトを巻き掛けた構成の無段変速機（ＣＶＴ：Continuously Variable Transmission）、つまりベルト式の無段変速機を内蔵している。 The transmission unit 1 is a unit that is mounted on a vehicle and changes the speed of power generated by an engine 2 (E/G) 2 as a drive source for driving. The transmission unit 1 has a built-in continuously variable transmission (CVT) in which an endless belt is wound around a primary pulley and a secondary pulley, that is, a belt-type continuously variable transmission.

変速ユニット１には、プライマリプーリの回転軸の端部を保持するための第１保持部材１１と、セカンダリプーリの回転軸３２（図２参照）を保持するための第２保持部材１２とが設けられている。 The transmission unit 1 is provided with a first holding member 11 for holding the end of the rotating shaft of the primary pulley, and a second holding member 12 for holding the rotating shaft 32 (see FIG. 2) of the secondary pulley. It is being

図２は、図１に示される切断面線Ａ－Ａにおける第１保持部材１１および第２保持部材１２の断面図である。 FIG. 2 is a sectional view of the first holding member 11 and the second holding member 12 taken along the section line AA shown in FIG.

第１保持部材１１には、変速ユニット１に設けられているバルブボディ（図示せず）から潤滑油としてのオイルが供給される第１油路２１が形成されている。第１油路２１は、上下方向に延びている。第１保持部材１１の側面には、第１油路２１の下端部と対向する位置に、放出口２２が設けられている。放出口２２は、第１保持部材１１の側面で開放され、その側面に近づくほど拡径する略円錐状に形成されている。また、第１保持部材１１には、第１油路２１と放出口２２との間に、第１油路２１の内径よりも小さい内径を有する絞り管部２３が形成されている。第１油路２１と放出口２２とは、絞り管部２３を介して連通している。 A first oil passage 21 is formed in the first holding member 11 to which oil as lubricating oil is supplied from a valve body (not shown) provided in the transmission unit 1 . The first oil passage 21 extends in the vertical direction. A discharge port 22 is provided on the side surface of the first holding member 11 at a position facing the lower end of the first oil passage 21 . The discharge port 22 is opened at the side surface of the first holding member 11 and has a substantially conical shape whose diameter increases as it approaches the side surface. Furthermore, a throttle tube portion 23 having an inner diameter smaller than the inner diameter of the first oil passage 21 is formed in the first holding member 11 between the first oil passage 21 and the discharge port 22 . The first oil passage 21 and the discharge port 22 communicate with each other via the throttle pipe section 23.

第２保持部材１２には、上下方向と直交する方向、たとえば、車両の前後方向における後側に凹む軸受凹部３１が形成されている。軸受凹部３１には、セカンダリプーリの回転軸３２の後端部が挿入される。回転軸３２の後端部は、軸受凹部３１内に挿入されて、その周面と軸受凹部３１の内周面との間に介在されるベアリング３３を介して第２保持部材１２に回転可能に支持されている。言い換えれば、回転軸３２の後端部にベアリング３３が外嵌され、そのベアリング３３が軸受凹部３１に嵌入されることにより、回転軸３２の後端部は、ベアリング３３を介して第２保持部材１２に回転可能に支持されている。 A bearing recess 31 is formed in the second holding member 12 and is recessed toward the rear in a direction perpendicular to the up-down direction, for example, in the longitudinal direction of the vehicle. A rear end portion of the rotating shaft 32 of the secondary pulley is inserted into the bearing recess 31 . The rear end of the rotating shaft 32 is inserted into the bearing recess 31 and is rotatable to the second holding member 12 via a bearing 33 interposed between the peripheral surface of the shaft and the inner peripheral surface of the bearing recess 31. Supported. In other words, the bearing 33 is fitted onto the rear end of the rotating shaft 32 , and the bearing 33 is fitted into the bearing recess 31 , so that the rear end of the rotating shaft 32 is attached to the second holding member via the bearing 33 . It is rotatably supported by 12.

第２保持部材１２は、第１保持部材１１の放出口２２が形成されている部分と隙間を空けて近接して配置される近接部３４を有している。近接部３４には、放出口２２に向けて開放された略半球状の受入口３５が形成されている。また、第２保持部材１２には、近接部３４と軸受凹部３１の後上端部との間に、第２油路３６が形成されている。第２油路３６は、近接部３４に接続されて、近接部３４と連通している。そして、第２油路３６は、近接部３４から軸受凹部３１の後上端部に近づくほど低く下がるように傾斜している。また、第２油路３６は、軸受凹部３１と連通している。 The second holding member 12 has a proximal portion 34 that is disposed adjacent to the portion of the first holding member 11 where the discharge port 22 is formed with a gap therebetween. A substantially hemispherical receiving port 35 that is open toward the discharge port 22 is formed in the proximal portion 34 . Furthermore, a second oil passage 36 is formed in the second holding member 12 between the proximal portion 34 and the rear upper end portion of the bearing recess 31 . The second oil passage 36 is connected to the proximal portion 34 and communicates with the proximal portion 34 . The second oil passage 36 is inclined so as to descend lower as it approaches the rear upper end of the bearing recess 31 from the proximal portion 34 . Further, the second oil passage 36 communicates with the bearing recess 31 .

＜作用効果＞
かかる構成により、第１保持部材１１では、第１油路２１を流れるオイルが第１油路２１から絞り管部２３を通して放出口２２に流入し、そのオイルが放出口２２から第２保持部材１２の受入口３５に向けて上下方向と交差ないしは直交する方向（第２方向）に放出される。 <Effect>
With this configuration, in the first holding member 11, the oil flowing through the first oil passage 21 flows from the first oil passage 21 through the throttle pipe section 23 into the discharge port 22, and the oil flows from the discharge port 22 to the second holding member 12. The liquid is discharged toward the receiving port 35 in a direction (second direction) that intersects or perpendicularly intersects with the vertical direction.

第２保持部材１２では、受入口３５が第２油路３６と連通している。そのため、第１保持部材１１の放出口２２から放出されるオイルが第２部材の受入口３５に受け入れられると、受入口３５から第２油路３６にオイルが流れ込み、そのオイルが第２油路３６を流れる。 In the second holding member 12 , the receiving port 35 communicates with the second oil passage 36 . Therefore, when the oil released from the discharge port 22 of the first holding member 11 is received by the reception port 35 of the second member, the oil flows from the reception port 35 into the second oil passage 36, and the oil is transferred to the second oil passage 36. It flows through 36.

よって、シール部材を用いずに、互いの間に隙が生じる第１保持部材１１と第２部材との間で、第１保持部材１１の第１油路２１から第２部材の第２油路３６にオイルを良好に受け渡すことができる。 Therefore, without using a sealing member, between the first holding member 11 and the second member in which a gap is created between each other, the first oil passage 21 of the first holding member 11 is connected to the second oil passage of the second member. 36 can be transferred well.

そして、第２保持部材１２では、第２油路３６と軸受凹部３１とが連通しているので、第２油路３６を流れるオイルが軸受凹部３１に流入する。これにより、軸受凹部３１内に配置されているベアリング３３およびそのベアリング３３に保持されている回転軸３２にオイルを供給することができ、回転軸３２およびベアリング３３をオイルで潤滑することができる。 In the second holding member 12 , the second oil passage 36 and the bearing recess 31 communicate with each other, so the oil flowing through the second oil passage 36 flows into the bearing recess 31 . Thereby, oil can be supplied to the bearing 33 disposed in the bearing recess 31 and the rotating shaft 32 held by the bearing 33, and the rotating shaft 32 and the bearing 33 can be lubricated with oil.

また、第１保持部材１１には、第１油路２１と放出口２２との間に、絞り管部２３が形成されている。これにより、第１油路２１から放出口２２に流出するオイルの流速が高まり、放出口２２から放出されるオイルの流速を高まるので、放出口２２から放出されるオイルを受入口３５に良好に到達させることができる。その結果、第１保持部材１１と第２部材との間からオイルが漏れることを良好に抑制することができる。また、第１油路２１から放出口２２に流れるオイルの流量が制限されるので、第１油路２１から第２油路３６に受け渡されるオイルの量が減り、オイルによる回転軸３２およびベアリング３３の回転抵抗を下げることができる。その結果、車両の燃費の向上を期待できる。さらには、第１油路２１から第２油路３６に受け渡されるオイルの低減分、第１油路２１から潤滑が必要な他の部材にオイルを供給することができる。 Furthermore, a throttle pipe portion 23 is formed in the first holding member 11 between the first oil passage 21 and the discharge port 22 . As a result, the flow rate of the oil flowing out from the first oil passage 21 to the discharge port 22 is increased, and the flow rate of the oil discharged from the discharge port 22 is increased, so that the oil discharged from the discharge port 22 can be transferred to the receiving port 35. can be reached. As a result, leakage of oil from between the first holding member 11 and the second member can be effectively suppressed. In addition, since the flow rate of oil flowing from the first oil passage 21 to the discharge port 22 is restricted, the amount of oil delivered from the first oil passage 21 to the second oil passage 36 is reduced, and the rotating shaft 32 and the bearings due to the oil are reduced. 33 rotational resistance can be lowered. As a result, it can be expected that the fuel efficiency of the vehicle will improve. Furthermore, the amount of oil transferred from the first oil passage 21 to the second oil passage 36 is reduced, and the oil can be supplied from the first oil passage 21 to other members that require lubrication.

＜他の実施形態＞
図３は、他の実施形態に係るオイル受渡し構造を示す断面図である。 <Other embodiments>
FIG. 3 is a sectional view showing an oil delivery structure according to another embodiment.

図３において、図２に示される各部に相当する部分には、それらの各部と同一の参照符号が付されている。また、以下では、その同一の参照符号が付された部分の説明を省略する。 In FIG. 3, parts corresponding to the parts shown in FIG. 2 are given the same reference numerals as those parts. Furthermore, in the following, explanations of parts with the same reference numerals will be omitted.

図３に示されるオイル受渡し構造では、図２に示されるオイル受渡し構造と比較して、受入口３５が放出口２２に向けて大きく開口している。これにより、受入口３５の上端は、放出口２２の上端に対して上方に離間しており、受入口３５の内面には、放出口２２から放出されるオイルを受け止めて、その受け止めたオイルを第２油路３６に導く受面５１が形成されている。 In the oil delivery structure shown in FIG. 3, the intake port 35 opens more widely toward the discharge port 22 than in the oil delivery structure shown in FIG. As a result, the upper end of the intake port 35 is spaced upward from the upper end of the discharge port 22, and the inner surface of the intake port 35 receives the oil released from the discharge port 22, and the received oil is A receiving surface 51 leading to the second oil passage 36 is formed.

これにより、放出口２２から放出されるオイルを受入口３５に良好に受け入れて、その受け入れたオイルを受入口３５から第２油路３６に流すことができる。その結果、第１保持部材１１と第２部材との間からオイルが漏れることを一層良好に抑制することができる。 Thereby, the oil discharged from the discharge port 22 can be well received in the receiving port 35, and the received oil can flow from the receiving port 35 to the second oil path 36. As a result, leakage of oil from between the first holding member 11 and the second member can be further suppressed.

また、受入口３５の周縁部の下部から第１保持部材１１側に延出する延出部５２が形成されている。延出部５２は、第１保持部材１１と上下方向と交差ないしは直交する方向にオーバラップする位置まで延出している。 Furthermore, an extending portion 52 is formed that extends from the lower portion of the peripheral edge of the receiving port 35 toward the first holding member 11 side. The extending portion 52 extends to a position where it overlaps the first holding member 11 in a direction that intersects or perpendicularly intersects with the up-down direction.

延出部５２が設けられていることにより、放出口２２以外から飛散してくるオイルの飛沫が受入口３５に受け入れられることを抑制でき、オイルのコンタミネーションを抑制することができる。 By providing the extending portion 52, it is possible to suppress oil droplets that are scattered from sources other than the discharge port 22 from being received in the receiving port 35, and it is possible to suppress oil contamination.
