Claims (1)
とにより変速可能で、変速時油圧作動されるべき
摩擦要素の作動油圧を変速シヨツクが軽減される
よう調圧する調圧弁を設けた自動変速機において
、 エンジン負荷に応じて開弁圧が変るリリーフ弁
を前記調圧弁及び摩擦要素間の作動油圧回路に接
続して設け、該リリーフ弁によりサージ圧を排除
するよう構成したことを特徴とする自動変速機の
変速シヨツク軽減装置。[Scope of Claim for Utility Model Registration] Gears can be changed by switching combinations of hydraulic actuation of various friction elements, and a pressure regulating valve is provided to regulate the hydraulic pressure of the friction elements to be hydraulically actuated during gear shifting so as to reduce the shift shock. In the automatic transmission, a relief valve whose opening pressure changes depending on the engine load is connected to the hydraulic pressure circuit between the pressure regulating valve and the friction element, and the relief valve is configured to eliminate surge pressure. Features a shift shock reduction device for automatic transmissions.
