  • Patent number: 5050447
    Abstract: In an automatic transmission mounted on a front engine and front drive vehicle, a valve body is positioned not to be obstructed by a vehicle side subframe, and lower sections of the transaxle casing, transaxle housing and rear cover form an oil reservoir space. Also, the lower part of the front differential device is isolated from the oil reservoir space by an oil reservoir plate and a side weir formed on the transaxle housing, but oil flows partly between the isolated areas. By this structure, the oil reservoir space is formed extending generally over the lower part of the integrated casing, and, in particular, is formed from the large space below the transaxle casing and the housing.

  • Patent number: 4971185
    Abstract: A plurality of oil channels formed in a casing is communicated with a single rotating hydraulic actuator. The casing comprises a transaxle casing on which a valve body is disposed, and a rear cover is fixed to the transaxle casing. The oil channels extend outwardly from a boss section in the casing and are radially arranged in a single plane of the rear cover. Oil from the hydraulic actuator is instantly exhausted through oil holes of an inner drum, an annular indented groove of the boss section, indented portions of sector shape and the oil channels.

  • Patent number: 4889621
    Abstract: A thick-walled, narrow-width oil strainer positioned in a space formed between the contact surfaces of the transaxle casing and transaxle housing of an automatic transmission is disclosed. Both the upper body and lower bodies of the oil strainer are constructed with an angled cross section to provide a deep suction section and a deep discharge section. A filter element is supported by being interposed between the peripheral edge sections and supporting bosses of the two bodies, and is slanted at a prescribed angle with respect to the suction section and the discharge section. The strainer is mounted with the right and left openings of the discharge section interposedly supported by the pump body and the transaxle casing, so that the oil discharged from the valve body is sucked directly into the pump through the suction section, and the oil in the oil sump is sucked into the pump through the filter element.
