摘要： An automatic transmission includes a transaxle casing and an overdrive casing fixed to the transaxle casing. A gear transmission mechanism is housed within the transaxle casing, and an overdrive mechanism is housed within the overdrive casing. Each of these is hydraulically controlled. A first hydraulic fluid accumulator for moderating sudden pressure changes within a part of a control mechanism for the gear transmission mechanism is housed within the transaxle casing, and a second hydraulic fluid accumulator for moderating sudden pressure changes within a part of a control mechanism for the overdrive mechanism is housed within the overdrive casing. Thereby a common type of transaxle casing may be used both for an automatic transmission assembly which incorporates such an overdrive mechanism and for an automatic transmission assembly which does not incorporate such an overdrive mechanism, and in the latter case no waste of space within the transaxle casing due to the unnecessary provision of space for the second hydraulic fluid accumulator need occur.

摘要： In a hydraulic torque converter having a torus of flatness ratio (L/H) within the range 0.82-0.9, the outer and inner contours of the turbine in a meridional plane through the axis of the turbine each comprises a combination of a plurality of circular arcs, wherein the ratios between the radii of the circular arcs constituting said outer contour is substantially less than 2, and the ratios between the radii of the circular arcs constituting said inner contour is substantially less than 2.As a result, fluid flows through the turbine stably without being biased, increasing the velocity of relative flow along the turbine blade, and raising the normal speed ratio at which the absolute flow is in the direction of no impact, enabling a higher stall torque ratio without reduction in efficiency.

摘要： A central differential device for differentially transmitting rotational power from the engine to the front wheel propeller shaft and the rear wheel propeller shaft in a vehicle is locked up step by step to restrict its differential operation gradually when the difference between front wheel rotational speed and rear wheel rotational speed is larger than a reference value while checking at each step before further increasing the degree of locking up if the difference is still larger than the reference value which may be changed for such each step.
