Claims

[Scope of Claim for Utility Model Registration] The first sun gear, second sun gear, and planetary carrier of the Ravigneau type planetary gear mechanism are connected to the input shaft via clutches or brakes, and these clutches or brakes are selectively operated as appropriate, and the ring gear is connected to the input shaft. The automatic transmission is configured to change the speed and transmit the rotation of the input shaft to the output shaft connected to the input shaft, the automatic transmission having a clutch drum connected to the input shaft, and the first gear and the gear being connected to each other via a one-way clutch. a first clutch device that connects and disconnects power transmission between the first clutch device and the input shaft; and a first clutch device disposed on the side of the first clutch device and in parallel with the first clutch device between the first sun gear and the input shaft. a second clutch device for intermittent power transmission; a brake drum disposed radially outward of the first and second clutch devices and connected to the second sun gear; and a brake band applied to the brake tom. a brake device disposed radially outwardly of the first and second clutch devices and laterally of the brake device, the second clutch device being arranged via a brake drum of the brake device;
a third clutch device that connects and disconnects power transmission between the sun gear and the input shaft, the clutch drums of the first, second and third clutch devices being integrally formed and connected to the input shaft; The clutch hub of the third clutch device is integrally formed at the tip of the brake 1 ram of the brake device, and the input terminal is connected between the splines of the clutch hub of the third clutch device and the splines on the inner surface of the clutch drum. An automobile characterized in that a clutch means for intermittently transmitting the rotation of the shaft is disposed, and further a protrusion is formed at the tip of the clutch hub of the third clutch device to prevent it from coming off from the clutch means. - Clutch device for automatic transmission.
