摘要： An automatic transmission includes: a gear transmission mechanism which can provide several speed stages according to selective supply of hydraulic pressures from a control system; a hydraulic fluid pump; a torque converter incorporating a lock up clutch which is selectively engaged or disengaged according to selective supply of pressure; a line fluid pressure control valve which receives a supply of pressurized hydraulic fluid from the pump and which provides a supply thereof, regulated to a line pressure level, to the control system; and a torque converter fluid pressure control valve which receives a supply of pressurized hydraulic fluid from the pump, and which provides a supply thereof to the torque converter as a source of torque converter pressure for filling it with hydraulic fluid and for selectively either engaging or disengaging the lock up clutch, this supply of torque converter pressure being regulated to a proper level by the torque converter fluid pressure control valve, when the supply of hydraulic fluid from the hydraulic fluid pump is plentiful, diverting therefrom an overflow flow of hydraulic fluid, which, when available, is supplied to the lubricating system of the gear transmission mechanism, to which the torque converter hydraulic fluid pressure is also always supplied via a throttle element.

摘要： In a hydraulic torque converter having a torus (10) of flatness ratio (L/H) within the range 0.82 - 0.9, the outer and inner contours of the turbine (6) in a meridional plane through the axis of the turbine each comprises a combination of a plurality of circular arcs (A,B,C and D,L respectively) wherein the ratios (B/C, B/A, C/A) between the radii of the circular arcs constituting the outer contour is substantially less than 2, and the ratio (E/D) between the radii of the circular arcs constituting the inner contour is also 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： 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.
