Abstract
【解決手段】係合機構の潤滑装置は、リニアソレノイドバルブSL6、第1バルブ64、第2バルブ65およびECU18を備える。リニアソレノイドバルブSL6は、第2ブレーキB2を係合させる係合圧を発生する。第1バルブ64は、リニアソレノイドバルブSL6で発生させた係合圧を第2ブレーキB2に供給する油路66に介在され、第2ブレーキB2を解放する場合に閉動作して油路66を閉じかつ第2ブレーキB2を係合する場合に開動作して油路66を開く。第2バルブ65は、第2ブレーキB2に潤滑油を供給する潤滑油路67に介在され、リニアソレノイドバルブSL6に連通されており、リニアソレノイドバルブSL6から係合圧が供給されることに開動作して潤滑油路67を開き、リニアソレノイドバルブSL6が係合圧を発生していないときには閉動作して潤滑油路67を閉じる。ECU18は、リニアソレノイドバルブSL6による係合圧の発生を制御する。
