    摘要： A cut-back pressure control device for a multi-speed automatic transmission includes a cut-back valve that has a spool which is controlled by both hydraulic pressure which changes in response to shifting of a sub-transmission unit between high-speed and low-speed modes and a hydraulic pressure which is established by the operation of the main transmission unit at 2nd or higher speeds. The spool is moved to a position where it interrupts the cut-back pressure when the main transmission unit selects the 1st speed while the sub-transmission unit is in the low-speed mode, whereas, when the sub-transmission unit is in the high-speed mode or when the main transmission unit selects the 2nd or a higher speed, the spool is held at a position at which it permits the supply of the cut-back pressure.

    摘要： In a shift control system of an automatic transmission, wherein the shift control system includes a first and a second transmissions capable of automatically switching speeds separately of one another, and the first and the second transmissions are shifted simultaneously or alternately, to thereby achieve multi-speed shifts, there is provided a system for starting and completing changes in rpm for the shift of rotary members of the second transmission during the operation of changes in rpm for the shift of rotary members of the first transmission, particularly when the first transmission is high gear shifted and the second transmission is shifted simultaneously, whereby the automatic transmission as a whole is up shifted, so that the shift characteristics can be maintained satisfactorily. In this case, an acting force of a frictionally engaging device during the operation of shift of the transmission is maintained at a predetermined value for a predetermined period of time so as to prevent a neutral portion on the intermediate portion of a series of torque transmitting system from occurring instantaneously to fluctuate an output torque.

    摘要： A transmission ratio selector mechanism having an upper manually operable gear lever (120) which is mounted (139, 250) intermediate its ends for pivoting about two perpendicular axes and a lower lever member (134) which is pivoted in a fixed mount (136) at its lower end (135) and is connected at its upper end (137) with the lower end (138) of the gear lever (120). The lower lever (134) is interconnected (133) intermediate its ends with a ratio selector shaft (112) whose longitudinal axis passes through the fixed mount (136). Pivoting of the gear lever (120) about one of the perpendicular axis causes axial displacement (W1, W2) of the selector shaft (112) in a direction parallel to its longitudinal axis and pivoting of the gear lever about the other perpendicular axis causes turning of the selector shaft about its longitudinal axis to move one or more ratio selector forks (101, 102). The gear lever (120) also has a range change position (H/L) which can only be reached when the associated transmission is in a neutral condition. The mounting (400) of the upper lever (120) may also vibrationally isolate the upper lever relative to the lowr lever (134).

    摘要： A lock-up valve includes a spool movable between a clutch engagement position wherein the lock-up clutch is engaged and a clutch release position wherein the engagement of the lock-up clutch is released. A spring biases the spool toward the clutch release position. The spool has a first pressure acting area and a second pressure acting area. A fluid pressure is applied to the first pressure acting area during operation in the m+th speed ratio (where: m is an integer) and the m+1th speed ratio to urge the spool against the spring toward the clutch engagement position. A lock-up timing valve is provided which allows the application of another fluid pressure to the second pressure acting area during shifting between the m th speed ratio and the m+1th speed ratio to urge said spool toward the clutch release position.

    摘要： A transmission range selection device for use with a vehicle transmission having a main gear box and auxiliary two-speed gear box provides control over both with a single, conventional shift lever. The shift lever is pivotally mounted in the tower of the main transmission which is fitted with a switch. Shift forks associated with the main gear box shift rails are conventional except for that fork associated with the highest speed gears which has an extended throat, permitting shift lever movement into positions adjacent and beyond the positions associated with the highest gears of the standard shift pattern. When moved to these additional shift positions, the shift lever selects the highest gears of the transmission and activates the switch which in turn shifts the auxiliary gear box from its lower range to its higher range.

    摘要： A torque transmitting system for transmitting torque from a drive shaft of an engine to an output shaft without transmitting torque variation comprises a friction clutch unit interposed between these shafts, a fluid pressure-operated actuating unit for engaging and disengaging the friction clutch unit, and vibration detecting means detecting vibration occurring in the engine or the torque transmitting system. In the system, means are provided for controlling the pressure of actuating fluid supplied to the fluid pressure-operated actuating unit on the basis of the output signal from the vibration detecting means thereby adjusting the difference between the rotation speed of the drive shaft and that of the output shaft, whereby the torque can be transmitted from the drive shaft to the output shaft without any substantial variation.
