Abstract

PURPOSE:To enable an automated speed change gear for side engine type front- drive car to be mounted on a body by displacing a frictional element located on the brake outer circumferential side so as to come near an engine with respect to a clutch, and offsetting an opening end of a clutch hydraulic supply passage from a remaining part thereof to the engine side. CONSTITUTION:A frictional element on the brake 22 outer circumferential side is displaced and arranged so as to come near an engine with respect to a clutch 14 as a frictional element on the inner circumferential side. An upper opening end 29 of a clutch hydraulic supply passage is offset by a fraction of said remaining parts 32, 34 of the clutch hydraulic supply passage. Hereby, a control valve 26 longitudinally connected with the upper part opening end 29 of the clutch hydraulic supply passage can be pulled by said offset fraction of the upper part opening end 29 into the engine side, while a transmission case upper part can be also pulled into the engine side, so that an automated speed change gear for a side-engine type front-drive car can be mounted without increasing car body width.

The automatic transmission used in front-wheel-drive vehicles with a built-in engine is arranged in tandem with the engine, and has a built-in clutch at the end of the transmission case farthest from the engine, arranged radially inward. It is common practice to have a built-in structure in which a surrounding brake (or clutch) is placed on the outside in the radial direction (Japanese Patent Laid-Open No. 55-40367, etc.). In addition, in this type of automatic transmission, the control valve that controls the above-mentioned speed change is placed above the transmission goose due to the installation space. It is being adopted (1: A made by ord company)
