摘要： PURPOSE:To reduce the size of a torque converter by a method wherein the section of the blade of an impeller is inclined such that the outer shell side is positioned further in front in a rotation direction than the inner core side at an angle at which a capacity factor is maximized. CONSTITUTION:A torque converter is formed with an impeller 1, a turbine 2, and a stator 3. A blade 21 is inclined so that a point P on an inner core 23 of the blade 21 is positioned further in a front in a rotation direction than a point Q on an outer shell 22. In which case, an enough amount of fluid flows along the outer shell 22 side, a capacity factor is increased. This constitution reduces the size of the torque converter.

摘要： PURPOSE:To improve the corrosion protective effect by forming of coarse material a part other than an abutting face of an installing bolt on a surface confronting the side for installation of a flange yoke shaft. CONSTITUTION:A bolt seat face (b) of coarse material of a flange yoke 101 is made thick, while a part in the vicinity thereof is provided with an escape part C. After coating treatment, an abutting face alone is cut to form the bolt seat face (b). It is thus possible to form the bolt seat face (b) without cutting a part in the vicinity thereof, thereby to increase coated surface, improve the corrosion protective effect and improve an appearance.

摘要： PURPOSE:To surely prevent a torque transmitting capacity from decreasing by connecting an oil chamber to communicate with an oil line system directly by an orifice provided in a rotary member and extending this orifice in a diametric direction of the rotary member. CONSTITUTION:The first and second oil chambers 25 and 26 are formed being partitioned by a lockup piston 21. An orifice 36, connecting the second oil chamber 26 or the second oil line system B to communicate with the first oil line system A, is formed in a driven side rotary shaft 20 forming the first oil line system A. The first oil chamber 25 is prevented from directly communicating with the second oil chamber 26 by this orifice 36. In this way, not only a shock at the time of releasing a lockup is relaxed but also a transmitting torque capacity can be surely prevented from decreasing.

摘要： PURPOSE:To improve lubricity by arranging the second clutch transmitting the driving force from the fourth planetary gear mechanism to the third planetary gear mechanism on the outer periphery side of the first clutch transmitting the driving force from the first and the second planetary gear mechanisms to the third planetary gear mechanism, and providing a lubricating oil passage between both clutch hubs. CONSTITUTION:Lubricating oil is fed to the first clutch 31 via the hollow hole 201a and the oil hole 201b of the first rotary shaft 201 and the oil hole 102a of a torque converter output shaft 102, and it is concurrently fed to the second clutch 32 via an oil hole 201c and between clutch hubs 313 and 323. The lubricating oil quantity of the oil holes 201b and 201c is determined by the lubricating pressure from the hollow hole 201a and the rotating centrifugal force of the first rotary shaft 201 regardless of the coupling or release of the first clutch 31. When the first clutch 31 is coupled, lubricating oil is fed to the outer diameter side from between the clutch hub 313 and a friction material and a separator, and it is discharged from grooves 312a and 322a formed on the piston coupling face after the first clutch 31 is coupled. Lubricity is improved in this way.

摘要： PURPOSE:To effectively use the lubricating oil of a planetary gear mechanism and simplify an oil feeding mechanism by linking the hub of a friction engaging element to a carrier on the outer periphery of the planetary gear mechanism and forming an oil passage for allowing lubricating oil pass through on this hub. CONSTITUTION:In a planetary gear mechanisms 22 consisting of a sun gear 221, planetary pinions 224, and a ring gear 222, the planetary pinions 224 are rotatably supported by a carrier 223 and a friction engaging element 53 is provided on the outer periphery thereof with its hub 534 being linked to the carrier 223. Since an oil passage 126 for allowing lubricating oil which lubricated the friction engaging element 53 to pass through is formed on the hub 534, oil which lubricated the planetary gear mechanism 22 passes through the oil passage 126 due to centrifugal force to be sent to the friction engaging element 53. Thus, by effectively using a large quantity of oil used by the planetary gear mechanism, the quantity of oil for lubrication and cooling can be reduced while simplifying an oil feeding mechanism.

摘要： PURPOSE:To reduce the abrasion of each forming member of a damper mechanism by having a tubulous part extendable in the axial direction at the radial inside of a second driven plate, and providing a centering part for abutting to that tubulous part in the radial direction at the inner peripheral end of a first driven plate. CONSTITUTION:A flange part 18g at the inner peripheral end of a disc 18 is supported by a peripheral wall 20e surface of a second driven plate 20b to secure the centering of a first driven plate. Namely, the flange part 18g is formed with a centering part. Consequently, the first and the second driven plates 19, 20 are hardly inclined each other to reduce the bearing of contact surfaces between them. The abrasion of both plates 19, 29 is thereby restrained to greatly improve the abrasion resistance of a damper mechanism 15.

摘要： PURPOSE:To remove an influence by rotation of a shaft by supporting a clutch drum by the shaft, supplying a pressure of oil through an oil path provided in the shaft further supplying the pressure of oil to the clutch drum when the shaft is not in rotation. CONSTITUTION:A clutch is provided with a clutch drum 440 integrally rotated with an input shaft, piston 450 operating a clutch 12 arranged in said drum 440 and a shaft member 600 supporting the internal peripheral part of an inner cylinder 448 of the drum 440. While the clutch is provided with oil paths 600a, b, d formed in the shaft member 600, oil path 448a provided in a cylinder 448 communicating with said oil paths 600a, b, d and oil paths 310a, 315a provided in a fixed member 310 communicating with the oil paths in the shaft member 600. And this shaft member 600, supplying operating oil in the drum 440 through the oil paths, is held in a condition of no-rotation before the clutch is engaged. Further the clutch 12 controls a speed change shift in cooperation with a friction engaging element 22, being further with it alternately engaged and disengaged.
