    摘要: A vehicle automatic transmission having a torque converter and a multiple stage transmission gear mechanism connected with the torque converter. The gear stage of the gear mechanism is selected in accordance with the vehicle operating condition. The transmission includes friction members. One of the friction members is engaged for a higher gear stage and disengaged for a lower gear stage whereas the other is disengaged for the higher gear stage and engaged for the lower gear stage. In shifting down from the higher gear stage to the lower gear stage, the other friction member is engaged after a predetermined time from the disengagement of the one friction member.

    摘要: A circuit for controlling hydraulic pressure of an automatic transmission includes a first shift device, a second shift device and a third shift device which make line pressure lead-through by selecting the predetermined combination of supply and exhaust of hydraulic pressure in accordance with the transmission stage in order to set the transmission stage of the automatic transmission in response to the driving condition of the vehicle. A switching device detects that a hydraulic pressure is supplied to an output line of the first shift device or an output line of the third shift device so that the third-speed and the fourth-speed are switched. The switching device also detects that the hydraulic pressure is supplied to an output line of the second shift device and an output line of the third shift device so as to shut out a line which is conducted to one of engaging elements being engaged at each time of the first-speed and the third-speed. By switching the combination of the supply and exhaust of hydraulic pressure, among devices which set each of the transmission stages, the number of parts and the required space can be reduced by shutting out the switching valves of line pressure.

    摘要: A hydraulic fluid pressure control system for a transmission which is shifted between two speed stages via a hydraulic actuator. A line pressure regulation valve receives supply of fluid pressure from a pump and produces a regulated line pressure. A switching valve receives supply of this regulated line pressure and selectively supplies it as an operating pressure to the fluid actuator, according to the opening and closing of a pilot port. This operating pressure is also supplied to the line pressure regulation valve for increasing the regulated value of the line pressure when the fluid actuator is being operated.

    摘要: A multiple-transmission-ratio transmission arrangement includes at least first and second transmission-ratio-establishing units, for example brake bands and/or clutches, having hydraulically activated and unactivated states and operative in the hydraulically activated state for establishing respective first and second transmission ratios. An arrangement for changing the transmission ratio of the transmission arrangement comprises, in combination, a source of hydraulic activating fluid and conduits connected to the source and to the hydraulically activatable transmission-ratio-establishing units. Electrically controllable valves in the conduits are operative for alternately permitting and preventing the supply of hydraulic activating fluid to the transmission-ratio-establishing units. An electrical transmission-ratio-selecting arrangement is connected to the valves and is operative for charging the transmission ratio of the transmission arrangement by causing the valves to effect a change of state of one of the units and an opposite change of state of the other of the units. Included is an electronic timing arrangement operative during a change of transmission ratio for delaying the change of state of one of the units until after the change of state of the other of said units has been effected.
