Title (EN) AUTOMATIC TRANSMISSION
(FR) TRANSMISSION AUTOMATIQUE
(JA) 自動変速機
Abstract:
(EN) A clutch unit for an automatic transmission, compact in the axial direction and having a simple oil path. One clutch (C3) and the other clutch (C4) that have hydraulic servos (20, 40), respectively, and cancel oil chambers (28, 48), respectively, are arranged at radially different positions in an axially overlapped manner. Oil is supplied from oil holes (b) to a hydraulic oil chamber (27) of the one clutch (C3) through a gap (B) between an inner wall of an outer drum (222) and an outer surface (71) of an inner drum (221), and lubrication oil is supplied from oil holes (a) to the cancel oil chamber (28) through a gap (A) between a clutch drum (42) of the other clutch (C4) and a rear surface (70) of the inner drum (221). In the gap (B), a groove (74) facing openings (b2) of the oil holes (b) are formed in the inner wall of the outer drum (222). In the gap (A), a space portion (A'), where no projections (72) having oil holes (b) are present, is placed in the same phase as the oil holes (a).
(FR) La présente invention concerne une unité d'embrayage pour une transmission automatique qui est compacte dans la direction axiale et qui comprend un trajet d'huile simple. Un premier embrayage (C3) et un deuxième embrayage (C4) comprenant des servomécanismes hydrauliques respectifs (20, 40) et des chambres de décompression d'huilée respectives (28, 48) sont disposés à des positons radialement différentes de manière axialement superposée. De l'huile arrive par des orifices pour l'huile (b) dans une chambre d'huile hydraulique (27) du premier embrayage (C3) par un espace (B) situé entre une paroi interne d'un tambour externe (222) et une surface externe (71) d'un tambour interne (221), et de l'huile de graissage est envoyée par les orifices pour l'huile (a) dans la chambre de décompression d'huile (28) par un espace (A) situé entre un tambour d'embrayage (42) du deuxième embrayage (C4) et une surface arrière (70) du tambour interne (221). Dans l'espace (B), une rainure (74) située en face des ouvertures (b2) des orifices pour l'huile (b) est formée dans la paroi interne du tambour externe (222). Dans l'espace (A), une partie (A'), dans laquelle il n'existe pas de parties saillantes (72) ayant des orifices pour l'huile (b), est placée dans la même phase que les orifices pour l'huile (a).
(JA) 軸方向にコンパクトに構成され、かつ簡単な油路でもって構成される自動変速機のクラッチユニットを提供する。 それぞれ油圧サーボ20、40及びキャンセル油室28、48を有する一方のクラッチC3と他方のクラッチC4とを、軸方向にオーバラップして径方向の異なる位置に配置する。一方のクラッチC3の作動油室27には、油孔bからアウタドラム22の内壁と、インナドラム22の外面71との間に形成された隙間Bを介して油が供給され、キャンセル油室28には油孔aから他方のクラッチC4のクラッチドラム42と、インナドラム22の背面70との隙間Aを介して潤滑油が供給される。隙間Bにおいてアウタドラム22の内壁には油孔bの開口部bと対面して溝74が形成され、また、隙間Aにおいては、油孔bを形成する突起部72が存在しない空間部分A’が油孔aと同位相に配置される。
