【0022】図1では、分岐された複数の潤滑路のうちのひとつであるダブルコーン7の軸受を潤滑する経路を示している。 [0022] FIG. 1 shows a path to lubricate the bearings of the double-cone 7 is one of a plurality of lubrication path branched. 流量調整弁34を通ってマニホールド30 Manifold 30 through the flow control valve 34
を出た潤滑油は、フロントケーシング16からキャリアガイド17、キャリア18を経由してキャリア軸19に連絡し、ダブルコーン7の軸受を潤滑している例である。 The output lubricating oil, the carrier guide 17 from the front casing 16, via the carrier 18 contact the carrier shaft 19, an example in which lubricates the bearings of the double cone 7. 複数に分岐された他の潤滑路は、例えば出力軸受や摩擦接触部への潤滑に供される。 Other lubrication path branched plurality is used to lubricate the example to output bearing or frictional contact. ここではマニホールド30において3つの潤滑路に分岐されている例を示し、 Here is an example that is branched into three lubrication passage in the manifold 30,

すなわちオイルクーラ28のファンによって冷却を2回できることになる。 That would be twice the cooling by a fan of the oil cooler 28. オイルクーラ28によって冷却された潤滑油は、マニホールド入口配管31からマニホールド30に入る。 The lubricating oil cooled by the oil cooler 28 enters the manifold inlet pipe 31 to the manifold 30.

【0025】この発明の潤滑構造は上記のような構成であり、摩擦式無段変速機の作動時において、オイルタンク10内の潤滑油はオイルポンプ11で吸上げられ、出口配管29を通ってオイルクーラ28に送り込まれる。 The lubrication structure of the present invention is configured as described above, during operation of the friction type continuously variable transmission, the lubricating oil in the oil tank 10 is sucked up by the oil pump 11 through the outlet pipe 29 It is fed to the oil cooler 28.

【0026】オイルクーラ28には、外部に設けたファンの送風が当っているので、該クーラ28内を通過する潤滑油は冷却され、冷却後の潤滑油は入口配管31からマニホールド30を通り、摩擦式無段変速機の潤滑必要部分に分配供給される。 [0026] the oil cooler 28, since the blower fan provided on the outside is hit, the lubricating oil passing through the said cooler 28 is cooled, lubricating oil after cooling through the manifold 30 from the inlet pipe 31, It is distributed and supplied to the lubrication requiring portion of the friction type continuously variable transmission. このとき、マニホールド30の各潤滑路32に設けた流量調整弁34により、潤滑必要部分に供給される潤滑油量を最適な油量に調節することができる。 At this time, can be adjusted by the flow rate adjusting valve 34 provided in each of the lubrication passage 32 of the manifold 30, the lubricating oil amount supplied to the lubrication requiring portion of the optimum amount of oil.

【0027】このように摩擦式無断変速機構21と遊星歯車機構2内部に供給され、各所要部所を潤滑した潤滑油は、潤滑油排出孔24を通してオイルタンク10に戻される。 [0027] Thus friction type continuously variable mechanism 21 and is supplied to the internal planetary gear mechanism 2, the lubricating oil lubricates the respective predetermined portions plants is returned to the oil tank 10 through the lubricant discharge hole 24. そして、再びオイルポンプ11により吸い上げられ、各外部配管とマニホールド30を通して各部に送られる、という循環を繰り返すと共に、この循環流の途中でオイルクーラ28を通過することにより冷却され、 Then, it is cooled by again sucked by the oil pump 11 and sent to each unit through the external pipe and the manifold 30, with repeated circulation of, passing through the oil cooler 28 in the course of this circulation flow,
また、ハウジング13自体もオイルクーラ28のファンで作られた空気流によって冷却されるので、潤滑油の温度上昇を抑えることができ、軸受や摩擦接触部の潤滑が十分に行なえ、出力軸8を高速回転させることができる。 Further, since the housing 13 itself is cooled by air flow created by the fan of the oil cooler 28, it is possible to suppress the temperature rise of the lubricating oil, lubrication of bearings and frictional contact is performed sufficiently, the output shaft 8 it can be rotated at a high speed.

【0028】 [0028]

【発明の効果】以上のように、この発明によると、ダブルコーンを用いた摩擦式無段変速機の潤滑油を循環させて潤滑必要部分を潤滑させることができると共に、循環する潤滑油をオイルクーラで冷却すると同時にハウジングも冷却するようにしたので、潤滑油の温度上昇を抑え、軸受や摩擦接触部の潤滑が確実に行なえ、出力軸を高速回転させることができる。 As is evident from the foregoing description, according to the present invention, by circulating the lubricating oil of a friction-type continuously variable transmission using a double cone it is possible to lubricate the lubrication necessary portion, the lubricating oil circulating oil since at the same time the housing when cooled in cooler and to cool, reduce the temperature rise of the lubricating oil, lubrication of bearings and frictional contact is performed reliably, the output shaft can be rotated at a high speed.

【0029】また、潤滑油の分配にマニホールドを用いることで、潤滑油の分配が容易になり、部品点数の削減による低コスト化及び組立工数の削減が可能となると共に、マニホールドに流量調整弁を設けることで、各潤滑部への潤滑量を容易に設定できる。 Further, by using a manifold to distribute the lubricating oil, the distribution of the lubricating oil is facilitated, reducing the cost and assembly man-hour by reducing the number of components together is possible, the flow control valve to the manifold by providing, it can be easily set lubrication amount to the lubricating portions.
