摘要： PURPOSE:To prevent a shift shock from being transmitted to the output side by disengaging a brake for engine braking temporarily when off-up shift and coast-down between two shift positions are performed during running with No.2 engine brake in selection. CONSTITUTION:In case the 1-2 off-up shift is made from the 1st to 2nd gearing position and an overdrive brake B0 of an overdrive planetary gearing unit is engaged, for example when a car is running down a slope in the 2-range condition, or in case coast-down is made from the 2nd to 1st position, the oil with pressure regulated by a linear solenoid valve SLU is supplied to the bottom oil chamber 656 of a low coast modulator valve 65, and thereby a spool 653 is pressed upward to retard feed of the B-3 engagement pressure. Thus a fast and reverse brake B3 is released temporarily to prevent the shift shock due to regripping between the overdrive direct clutch C0 and overdrive brake B0 from being transmitted to the output side.

摘要： PURPOSE:To improve sealing ability between a substrainer and a separate plate by a method wherein the substrainer is formed such that a frame body on the outer peripheral surface of which a mesh member is formed and a flange part having an oil inflow port formed in the upper part of the frame body are securely pressed against the oil hole of the separate plate. CONSTITUTION:A foreign matter, e.g. iron powder, dust, mixed in oil flowing from an upper oil passage 110 to a lower oil passage 111 is caught by a mesh member 112 of a substrainer 105. In this case, since a flange part 117 having an oil inflow port formed in the upper part of a frame body 113 is securely pressed against an oil hole 106a of a separate plate 106, sealing between the substrainer 105 and the separate plate 106 is effected through the resilient force of flange part 117.

摘要： PURPOSE:To heighten responsiveness by providing a lock-up control valve for suitably controlling a drain oil port to be communicated with a drain or supply port by control pressure from a linear solenoid valve. CONSTITUTION:When the control pressure of a linear solenoid valve 16 is reduced in response to an external signal of a lowering of car velocity or the like, a lock-up control valve 15 moves a spool 15a in the direction of throttling a drain oil port 12a and a drain port 14, whereby oil pressure in the first oil chamber 9 is increased to reduce a pressure difference from an oil chamber 10 and the engagement force of a clutch 5 is lessened. At this time, when an outer hull 2 of a torque converter 1 is contracted by a lowering of centrifugal force or the like to increase oil pressure in the second oil chamber 10, the spool 15a is further moved by an orifice 13 to communicate the drain oil port 12a with a supply port 11a, so that oil pressure in the first oil chamber 9 is increased to attain the suitable differential pressure state in order to quickly correspond to the control pressure of a control chamber 17a.

摘要： PURPOSE:To accurately control a back pressure in a pressure regulating valve for regulating oil pressure of an automatic transmission by providing a regulating screw for regulating a load in opposition to a spring for giving the load to a spool end face. CONSTITUTION:A pressure regulating valve gives a signal pressure to the end face of a spool 533 or the end face of a land 533b and moves the spool 533 in accordance with this signal pressure to regulate oil pressure. A regulating screw 551 for regulating a spring load is provided in opposition to a spring 541 which is brought into contact with one end of the spool 533 to give the load to the end face, the control an outputted back pressure as is set. Thus, a throttle pressure having no dispersion is inputted as the signal pressure of an accumulator control valve. Thereby, an accurate back pressure can be fed to the accumulator of a brake and a clutch connected to the output side of the accumulator control valve.

摘要： PROBLEM TO BE SOLVED: To provide the resistance against pitching, wear, breakage, and fatigue by applying gas soft nitriding treatment on steel containing a specific weight ratio of C, Si, Mn, P, S, Cr, and Mo and providing a tooth face with specific compound layer and diffusion layer. SOLUTION: The steel which contains 0.18 to 0.23 weight % of C, 0.15 to 0.35 weight % of Si, 0.60 to 0.85 weight %, of Mn, 0.03 weight % or less of P, 0.03 weight % or less of S, 0.90 to 1.20 weight % of Cr, and 0.15 to 0.30 weight %, of Mo and is composed of the remaining compounds such as Fe and impurities is heat treated, and then a raw material of gear shape is treated by a gas soft nitriding method. The mixed gas composed of Co2 and NH3 containing nitrogen gas is used, gas temperature is 530 to 565 deg.C, and one step treatment is done for two hours. Consequently, a compound layer having a thickness of 2 to 12 μm and a diffusion layer having a hardness of Hv 50 or more which is higher than that of the steel itself and a thickness of 200 μm or more are formed on a tooth face. As a result, it is possible to maintain sufficient resistance against wear and the resistance against breakage and fatigue without affecting gear noise greatly even if a porous layer is peeled off.

摘要： PROBLEM TO BE SOLVED: To quickly converge vibration and improve sound eliminating effect by pressure welding or sticking a damping member on the inside or outside of a drum-like member within a transmission. SOLUTION: The rotating vibration is generated in the engaging surface between a frictional material 4 on a brake hub 3 side connected to a carrier as rotating element and a separator plate 2 on a transmission case 1 side by the play between the claw part and groove part of the spline engagement part of the separator plate 2 by a static slip. This rotating vibration is transmitted to a piston 6 for pressing the separator plate 2. Therefore, an annular elastomer 81 is integrated near the end surface of the major diameter part 61, which forms the maximum amplitude part in vibration, on the inside of the piston 6 as the drum-like member in the state where an initial stress is loaded between the piston 6 and a rigid ring 82. Thus, the annular elastomer 81 is deformed according to the radial expanding and contracting deformation of the major diameter part 61 to change vibration to thermal energy, whereby vibration energy can be damped.

摘要： PROBLEM TO BE SOLVED: To improve the durability of a transmission clamp device to vibrations with a simple structure. SOLUTION: A clamp device 1 is pressed out of spring steel to integrally comprise a clamp body 10, a tightened part 20 and an urging means 30. The height H of a spacer part 31 of the urging means 30 is set longer than the fitting height of the tightened part 20, to thereby cause a pressure part 32 to pressure a valve body to which the tightened part 20 has been bolted. The tightened part at only one position and the simple structure of the clamp device 1 suffice to pressure the valve body at two positions of the tightened part 20 and the pressure part 32 and thus to suppress vibrations.

摘要： PURPOSE:To eliminate generation of a speed change shock and further to shorten a speed change time by performing the second speed change judgment during the simultaneous speed change of a main and speed sub change units. CONSTITUTION:A means of detecting an engine load changing speed is provided for estimating the next speed change judgment. A speed change output control means judges whether or not the engine load changing speed is a predetermined value or more when performed the first speed change judgment where down/up shift speed changes are performed by main and subspeed change units. In the case that the engine load changing speed is the predetermined value or more, the second speed change judging is on standby without performing the first speed change output by estimating the second speed change judgment performed, and the second speed change output is performed immediately when the second speed change judgment is performed. That is, the second speed change output is performed directly without performing the first speed change output, so that a total speed change time is shortened. In the case that the engine load changing speed is smaller than the predetermined value, the first speed change output is performed after the lapse of preset time from the first speed change judgment.
