摘要： A control system for an automatic transmission of a vehicle is disclosed. The automatic transmission operates in a manual operating mode in which a shift position of the automatic transmission can be changed according to a shift instruction issued by a driver of the vehicle, or in an automatic operating mode in which the shift position is automatically selected. In the control system, a slow running intention of the driver is detected. A first shift position is set to a starting shift position at the time of starting the vehicle when the slow running intention of the driver is not detected in the manual operating mode. A second shift position which is lower in transmission gear ratio than the first shift position is set to the starting shift position when the slow running intention of the driver is detected in the manual operating mode.

摘要： A shift control system is arranged such that a shift lever 201 is movable to a “P” position, an “R” position, an “N” position, a “D5” position and a “D4” position along a first shift guide path 211, it is movable also from the “D4” position to a “3/M” position along a connection shift guide path 212, and it is movable also along a second shift guide path 213, from the “3/M” position into a direction different from that of the connection shift guide path 212. When the shift lever is shifted to the “D5” position, the transmission is set into an automatic shift control with forward drive speed ratios up to the FIFTH speed ratio. When the shift lever is shifted to the “D4” position, the transmission is set into an automatic shift control with forward drive speed ratios up to the FOURTH speed ratio. When the shift lever is shifted from the “D4” position to the “3/M” position along the connection shift guide path 212, the transmission is set into a “3” range, where an automatic shift control is executed with forward drive speed ratios up to the THIRD speed ratio. Then, the shift lever at the “3/M” position is swiveled along the second shift guide path 213 to shift the speed ratio of the transmission manually in steps.

摘要： The durability of the entire metal ring assembly is enhanced by increasing the wear life of the radially inner surface of the metal ring of the innermost layer which is the layer which is most easily fractured. A belt for a continuously variable transmission is formed by supporting a large number of metal elements on a metal ring assembly wherein multiple sheets of endless metal rings are layered. The thickness of the metal ring of the innermost layer is different from the thickness of the metal rings of layers other than the innermost layer. The thickness of the metal ring of the innermost layer is set so that the stress amplitude applied to the radially outer surface of the metal ring of the innermost layer is not more than the stress amplitude applied to the radially outer surfaces of the metal rings of layers other than the innermost layer. By setting the thickness of the metal ring of the innermost layer at 0.042 mm to 0.161 mm when the thickness of the metal rings of layers other than the innermost layer is 0.185 mm, the stress amplitude &sgr;a1 applied to the metal ring of the innermost layer becomes lower than the stress amplitude &sgr;an of 25.65 kgf/- mm2 applied to the other metal rings. Thus the durability of the metal ring of the innermost layer can be enhanced to increase the life span of the entire metal ring assembly.

摘要： The relation of the length h1 of the V surface of each metal element to the saddle primary thickness h2 is determined such that the strength of the metal element for the Hertz's pressure generated on the V surface 2 from the normal force P which acts on the V surface 2 when the element engages in the V-shaped groove of a pulley and the strength for the bending moment which is produced by the normal force P on the saddles 1 of the metal element are made substantially equal to each other. Also, the relation of the length of the V surface to the saddle primary thickness is determined such that the fatigue life by the Hertz's pressure which acts on the V surface and the fatigue life by the bending moment which acts on the saddles are made substantially equal to each other. The length h1 of the V surface, which is determined in the above mentioned ways, can be about 0.26-1.0 of the saddle primary thickness h2. Thus, the miniaturization and lightening of the element is achieved by this rational method which equalizes the fatigue life for the whole body of the element while providing the element with necessary strengths.

摘要： A system for controlling gear (gear ratio) shifting in an automatic transmission mounted on a vehicle, including a shift control means for generating a shift command to upshift from one gear (gear ratio) currently established to a next gear (gear ratio) by determining a command to the solenoid valves to discharge the pressurized oil from the frictional engaging elements that establish the current gear (gear ratio) so as to slip-control the frictional engaging elements, and to charge the pressurized oil to the frictional engaging elements that establish the next gear (gear ratio) to be shifted to. The system includes a first step for determining the command such that an actual slip rate of the frictional engaging elements that establish the current gear (gear ratio) converges to a first desired slip rate, a second step for determining the command such that the actual slip rate of the frictional engaging elements that establish the current gear (gear ratio) converges to a second desired slip rate, maximum slip rate detecting means for detecting a maximum actual slip rate, slip rate difference calculating means for calculating a difference between the detected maximum actual slip rate and the second desired slip rate, command correcting means for correcting the command in response to the calculated difference, and command storing means for storing the corrected command to be used as the command in the first step in controlling a next upshift. This arrangement can avoid the clutches (and brakes) from being suffered excessive slippage, thereby improving the service life of the clutches and brakes and making the control to smooth shift to that for the next gear (gear ratio).

摘要： In a sealing device, a crank-shaped oil channel is defined in an abutment of a sealing ring for sealing between a shaft member and a housing which surrounds the shaft member and is rotatable relative the shaft member. The crank-shaped oil channel is comprised of a first oil channel portion and a second oil channel portion which extend axially, and a third oil channel portion which connects the first and second oil channel portions to each other. If the sealing ring is thermally expanded circumferentially due to a change in temperature, the sectional area of the flow path in each of the first and second oil channel portions is varied, but the sectional area of the flow path in the third oil channel portion is not substantially varied. Therefore, it is possible to leak a given amount of an oil from one side of the sealing ring through the crank-shaped oil channel to the other side, thereby preventing the wearing of the shaft member caused by foreign matter, such as an iron powder, contained in the oil.

摘要： A hydraulic servo unit for changing the swash plate angle of a continuously variable transmission to vary its speed reduction ratio comprises a cylinder whose chamber is divided into a rod-side chamber and a head-side chamber by a piston slidably fitted therein. The rod-side chamber is supplied with working oil under predetermined hydraulic pressure through a first hydraulic pressure supply passage. A second hydraulic pressure supply passage is connected to the head-side chamber through a duty-cycle-controlled first solenoid-operated valve, and a drain hydraulic passage is connected to the second hydraulic pressure supply passage through a second duty-cycle-controlled solenoid-operated valve. The first and second solenoid-operated valves are simultaneously actuated with different duty cycles. The difference between the different duty ratios is varied to vary the rate at which the working oil flows into or out of the head-side chamber through the second hydraulic pressure supply passage, in a wide range from a very low rate to a high rate. The working oil can accurately be controlled especially in a very low rate range for operating the hydraulic servo unit at very low speed. Therefore, continuously variable transmission can precisely and smoothly be controlled for varying the speed reduction ratio.
