Description

本発明は、自動車等の車両に搭載される無段変速装置又は自動変速装置に関する。   The present invention relates to a continuously variable transmission or an automatic transmission that is mounted on a vehicle such as an automobile.

例えば、ＦＦ車に搭載されたクランク軸横置きエンジンの自動変速装置は、ケーシング内に、エンジン動力が伝達される入力軸と、該入力軸に装着された遊星歯車機構と、上記入力軸の回転が遊星歯車機構を介して伝達される中間軸と、該中間軸の回転が差動機構を介して伝達される出力軸とを収容した構造となっている。   For example, an automatic transmission for a crankshaft horizontally mounted engine mounted on an FF vehicle includes an input shaft in which engine power is transmitted, a planetary gear mechanism mounted on the input shaft, and rotation of the input shaft. Is configured to accommodate an intermediate shaft that is transmitted through a planetary gear mechanism and an output shaft through which rotation of the intermediate shaft is transmitted through a differential mechanism.

また、特許文献１には、コネクタの組み付け性の向上を図るために、入力軸に設けられた遊星歯車機構を覆うケーシングと、該ケーシングの後方側にて中間軸を覆うケーシングとの接合コーナ部にコネクタ配索用ボス部を形成し、該ボス部内にソレノイドバルブのワイヤハーネスを配索したものが開示されている。   Further, in Patent Document 1, in order to improve the assembling property of the connector, a joining corner portion between a casing covering a planetary gear mechanism provided on an input shaft and a casing covering an intermediate shaft on the rear side of the casing. A connector wiring boss portion is formed in the boss portion, and a solenoid valve wire harness is routed in the boss portion.

一方、上記自動変速装置では、遊星歯車機構から発生するギヤ音が耳障りとなる場合があり、このギヤ音の低減が要請されている。このようなギヤ音の低減を図るには、ケーシングの遊星歯車機構に臨む部分に中空状の防音壁を形成することが有効であると考えられる。
特開平１１−８２６４５号公報 On the other hand, in the above automatic transmission, the gear noise generated from the planetary gear mechanism may be annoying, and there is a demand for reduction of this gear noise. In order to reduce such gear noise, it is considered effective to form a hollow soundproof wall in a portion of the casing facing the planetary gear mechanism.
JP-A-11-82645

そこで、上記遊星歯車機構の後方側に形成したボス部を防音壁として利用することが考えられる。しかしながら、上記従来の単に後方に設けられただけのボス部を防音壁として利用するだけでは、前方及び上方への防音効果が得られず、ギヤ音を抑制できない。   Therefore, it is conceivable to use a boss formed on the rear side of the planetary gear mechanism as a soundproof wall. However, if the conventional boss portion simply provided behind is used as a soundproof wall, the soundproof effect to the front and the top cannot be obtained, and the gear sound cannot be suppressed.

ここで、防音壁をケーシングの遊星ギヤ機構の周囲に形成することが考えられるが、このようにした場合はケーシングの構造が複雑となり、コストが上昇するという問題が生じる。   Here, it is conceivable to form a soundproof wall around the planetary gear mechanism of the casing. However, in this case, the structure of the casing becomes complicated and the problem of an increase in cost arises.

本発明は、上記従来の状況に鑑みてなされたもので、コネクタの組み付け性の向上を図りつつ、かつ構造の複雑化，コストの上昇を招くことなく、遊星ギヤ機構からのギヤ音を抑制できる変速装置を提供することを目的としている。   The present invention has been made in view of the above-described conventional situation, and can suppress gear noise from the planetary gear mechanism while improving the assembling property of the connector and without complicating the structure and increasing the cost. The object is to provide a transmission.

本発明は、ケーシング内に、遊星ギヤ機構を有する入力軸と、該入力軸の回転が遊星ギヤ機構を介して伝達される中間軸と、該中間軸の回転が伝達される出力軸とが収容され、上記遊星ギヤ機構の背面部が上記中間軸，出力軸の軸構成部品で囲まれており、上記ケーシングの遊星ギヤ機構の下方にオイルパンが配設された変速装置において、上記ケーシングの上面部の遊星ギヤ機構に臨む部分に該遊星ギヤ機構に沿うようにブリーザ室が設けられ、上記ケーシングの前面部の上記遊星ギヤ機構に臨む部分に該遊星ギヤ機構に沿うように通路が形成され、該通路の下端開口が上記オイルパン内に連通されるとともに、上記ケーシング内に配置されたソレノイドバルブの接続ハーネスが上記通路の下端開口から上端開口に向けて配索され、該通路の上端開口部に上記接続ハーネスと外部接続ハーネスとを接続する中間コネクタが装着されていることを特徴としている。   According to the present invention, an input shaft having a planetary gear mechanism, an intermediate shaft to which rotation of the input shaft is transmitted via the planetary gear mechanism, and an output shaft to which rotation of the intermediate shaft is transmitted are accommodated in a casing. In the transmission in which the rear portion of the planetary gear mechanism is surrounded by the shaft and component parts of the intermediate shaft and the output shaft, and the oil pan is disposed below the planetary gear mechanism of the casing, the upper surface of the casing A breather chamber is provided along the planetary gear mechanism at a portion facing the planetary gear mechanism, and a passage is formed along the planetary gear mechanism at a portion facing the planetary gear mechanism at the front portion of the casing; A lower end opening of the passage communicates with the oil pan, and a solenoid valve connection harness arranged in the casing is routed from the lower end opening of the passage toward the upper end opening, and the passage Intermediate connector for connecting the connection harness and the external connection harness to the upper end opening is characterized in that it is mounted.

本発明に係る変速装置によれば、遊星ギヤ機構の背面部が中間軸，出力軸の軸構成部品で囲まれ、ケーシングの上面部の遊星ギヤ機構に臨む部分にはブリーザ室が設けられ、上記ケーシングの前面部の遊星ギヤ機構に臨む部分には通路が形成されているので、遊星ギヤ機構の略全周に渡って防音壁を設けたこととなり、耳障りなギヤ音を抑制できる。   According to the transmission according to the present invention, the rear portion of the planetary gear mechanism is surrounded by the shaft component parts of the intermediate shaft and the output shaft, and the breather chamber is provided in the portion facing the planetary gear mechanism on the upper surface portion of the casing. Since a passage is formed in the front portion of the casing facing the planetary gear mechanism, a soundproof wall is provided over substantially the entire circumference of the planetary gear mechanism, and an unpleasant gear sound can be suppressed.

本発明では、上記通路の下端開口から上端開口に向けて接続ハーネスが配索され、該通路の上端開口部に上記接続ハーネスと外部接続ハーネスとを接続する中間コネクタが装着されているので、上記通路を防音壁及びハーネス配索通路に兼用しつつ、車載時の接続ハーネスと外部接続ハーネスとの組み付け性を向上できる。   In the present invention, the connection harness is routed from the lower end opening of the passage toward the upper end opening, and the intermediate connector for connecting the connection harness and the external connection harness is attached to the upper end opening of the passage. Assembling property of the connection harness and the external connection harness when mounted on the vehicle can be improved while the passage is also used as a soundproof wall and a harness routing passage.

また上記ギヤ音を抑制する防音壁を、中間軸，出力軸の軸構成部品，ブリーザ室，ハーネス配索通路といった既存のものを有効利用して構成したので、ケーシングの構造が複雑化したり、コストが上昇したりすることはない。   In addition, the sound barrier that suppresses the gear noise is constructed by effectively using existing components such as the shaft components of the intermediate shaft, the output shaft, the breather chamber, and the harness routing passage, which complicates the casing structure and reduces the cost. Will not rise.

The lower side of the back surface of the planetary gear mechanism 5 is covered by the differential mechanism 7, and an oil pan 23 is located below the planetary gear mechanism 5.

上記ケーシング２の上面部には中空状のブリーザ室３０が形成されている。このブリーザ室３０は、ケーシング２内の圧力が高くなるのを防止するために、内部の空気を排出孔３０ａから外部に排出する際に、該空気に含まれているオイルミストを分離してオイルパン側に戻すためのものであり、外側ケース体２ｂの内側ケース体２ａとの合面部に形成されている。上記排出孔３０ａにはブリーザプラグ（不図示）が挿着されている。   A hollow breather chamber 30 is formed on the upper surface of the casing 2.

上記通路３１の下端開口部３１ａはケーシング２内に開放されてオイルパン２３に連通している。また上記通路３１の上端開口部３１ｂは遊星ギヤ機構５の上端部付近にて外方に連通している。この上端開口部３１ｂには中間コネクタ３２がシール部材３２ａを介在させて挿着されている。この中間コネクタ３２の接続部３２ｂは上端開口部３１ｂから外方に突出している。また上記中間コネクタ３２はこれに一体形成されたフランジ３３を介して外側ケース体２ｂにボルト３４により固定されている。   A lower end opening 31 a of the passage 31 is opened in the casing 2 and communicates with the oil pan 23. The upper end opening 31 b of the passage 31 communicates outward near the upper end of the planetary gear mechanism 5. An intermediate connector 32 is inserted into the upper end opening 31b with a seal member 32a interposed. The connecting portion 32b of the intermediate connector 32 protrudes outward from the upper end opening 31b. The intermediate connector 32 is fixed to the outer case body 2b by a bolt 34 via a flange 33 formed integrally therewith.

そして上記雄側コネクタ２７は、上記中間コネクタ３２に下側から挿入結合されている。なお、上記雄側コネクタ２７と、上記中間コネクタ３２との結合はこの中間コネクタ３２を外方に取り外した状態で行なわれる。そしてこの結合状態で、中間コネクタ３２のフランジ３３がケーシング２に固定される。このようにして通路３１内には接続ハーネス２６が配索されている。   The male connector 27 is inserted and coupled to the intermediate connector 32 from below. The male connector 27 and the intermediate connector 32 are coupled together with the intermediate connector 32 removed outward. In this coupled state, the flange 33 of the intermediate connector 32 is fixed to the casing 2. In this way, the connection harness 26 is routed in the passage 31.

また上記中間コネクタ３２の接続部３２ｂには、上方から外部接続ハーネス３５の雌側コネクタ３６が接続されている。この外部接続ハーネス３５は不図示の制御装置に接続されている。   The female connector 36 of the external connection harness 35 is connected to the connection portion 32b of the intermediate connector 32 from above. The external connection harness 35 is connected to a control device (not shown).

本実施形態によれば、遊星ギヤ機構５の背面部上側を従動側可動シーブ１７及び油圧プレート１８で、背面部下側を差動機構７で覆い、上記遊星ギヤ機構５の上面部をブリーザ室３０により覆うとともに、前面部を通路３１により覆ったので、遊星ギヤ機構５の全周に渡って防音壁を設けたこととなり、耳障りなギヤ音を抑制できる。   According to the present embodiment, the upper side of the planetary gear mechanism 5 is covered with the driven movable sheave 17 and the hydraulic plate 18 and the lower side of the rear part is covered with the differential mechanism 7, and the upper surface of the planetary gear mechanism 5 is covered with the breather chamber 30. Since the front portion is covered with the passage 31, a soundproof wall is provided over the entire circumference of the planetary gear mechanism 5, and an unpleasant gear sound can be suppressed.

本実施形態では、上記通路３１を雄側コネクタ２７が挿通可能な大きさとするとともに、下端開口部３１ａをオイルパン２３内に連通させ、上端開口部３１ｂを外方に連通させるとともに、該上端開口部３１ｂに中間コネクタ３２を配置したので、雄側コネクタ２７をこの中間コネクタ３２に結合し、該中間コネクタ３２をケーシング２に固定することで接続ハーネス２６を容易に配索することができる。   In the present embodiment, the passage 31 is sized to allow the male connector 27 to be inserted, the lower end opening 31a is communicated with the oil pan 23, the upper end opening 31b is communicated outward, and the upper end opening is opened. Since the intermediate connector 32 is arranged in the portion 31b, the connection harness 26 can be easily routed by coupling the male connector 27 to the intermediate connector 32 and fixing the intermediate connector 32 to the casing 2.

また上記通路３１の上端開口部３１ｂに中間コネクタ３２を挿着し、該コネクタ３２に外部接続ハーネス３５の雌側コネクタ３６を上方から接続したので、上記通路３１を防音壁及びハーネス配索通路に兼用しながら、接続ハーネス２６と外部接続ハーネス３５の組み付け性を向上できる。   Further, since the intermediate connector 32 is inserted into the upper end opening 31b of the passage 31, and the female connector 36 of the external connection harness 35 is connected to the connector 32 from above, the passage 31 is used as a soundproof wall and a harness routing passage. The combinedness of the connection harness 26 and the external connection harness 35 can be improved while also being used.

本実施形態では、上記ギヤ音を抑制する防音壁を、従動側可動シーブ１７，油圧プレート１８，差動機構７，ブリーザ室３０及び通路３１といった既存のものを有効利用して構成したので、ケーシング２の構造が複雑化したり、コストが上昇したりすることはない。またケーシング２に通路３１を膨出形成したので、ケーシング自体の剛性を高めることもできる。   In the present embodiment, the soundproof wall that suppresses the gear noise is configured by effectively using the existing ones such as the driven movable sheave 17, the hydraulic plate 18, the differential mechanism 7, the breather chamber 30, and the passage 31. The structure of 2 does not become complicated and the cost does not increase. Further, since the passage 31 is formed to bulge in the casing 2, the rigidity of the casing itself can be increased.

なお、上記実施形態では、Ｖベルト式無段変速装置に適用した場合を例にとって説明したが、本発明は、多板クラッチ機構による自動変速装置にも適用可能である。   In the above embodiment, the case where the present invention is applied to a V-belt continuously variable transmission has been described as an example. However, the present invention can also be applied to an automatic transmission using a multi-plate clutch mechanism.
