1 shows a transmission operating device according to the present invention. This device uses the same actuator as the conventional actuator as the shift cylinder 20 and the select cylinder 40.

Therefore, both cylinders 20, 40 have first cylinder chambers 21, 41 and second cylinder chambers 22, 42. Main pistons 23 and 43 are provided in the first cylinder chambers 21 and 41, and the first cylinder chambers 21 and 41 are separated by the pistons 23 and 43 into first pressure chambers 24 and 44.
And the second pressure chambers 25 and 45. On the other hand, the second
Free pistons 26, 46 are provided in the cylinder chambers 22, 42, respectively.
The second cylinder chambers 22, 42 are separated from the atmospheric pressure chambers 27, 47 and the third pressure chamber 2 by the pistons 26, 46.
8,48. The pressure action areas of the free pistons 26, 46 are equal to the main pistons 23, 4
3 bigger than that.

The first pressure chambers 24, 44 of the cylinders 20, 40 are connected via first electromagnetic switching valves 29, 49, and the second pressure chambers 25, 45 are connected to the second electromagnetic switching valves 30, 50. The third pressure chambers 28 and 48 are connected to the air tank A via third electromagnetic switching valves 31 and 51, respectively.

These electromagnetic switching valves 29, 30, 31, 4
9, 50 and 51 are all in the demagnetized state,
The pressure chambers 24, 25, 28, 44, 45, and 48 are communicated with the air tank A in an excited state by releasing the air chambers 25, 28, 44, 45, and 48 to the atmosphere. These electromagnetic switching valves 29, 3
0, 31, 49, 50 and 51 are controlled by the controller B.

In FIG. 1, the shift cylinder 20 and the select cylinder 40 are arranged so as to correspond to the shift pattern C. Therefore, the main piston 23 of the shift cylinder 20 is positioned at the intermediate position NE of the first cylinder chamber 21.
In a state in which are located, becomes the select cylinder 40 is operational, the main piston 43 of the selector cylinder 40 is moved corresponding to N _1, N _2, N ₃ shift pattern C, select the transmission Perform the action. The main piston 43 of the select cylinder 40 is connected to the first cylinder 41.
The shift cylinder 20 is operable in a state where the shift cylinder 20 is located at the position S ₁ , the middle position S ₂ , and the position S ₃ , the leftmost position. 23 denotes F _{1 to} R ₁ of the shift pattern C,
Moves corresponding to _{F 2 ~R 2, F 3 ~R} 3, performs a shift action of the transmission.

The control of the cylinders 20 and 40 will be described below by way of an example.

When the shift lever located at N _{1 of the} shift pattern C is moved to F ₁ , each cylinder 20,
40 is controlled as follows. In a state where the shift lever is positioned at N ₁ of the shift pattern C, all of the electromagnetic switching valve 29,30,31,49,50,51 are demagnetized. Therefore, all the pressure chambers 24, 25, 28,
44,45,48 is open to the atmosphere, as shown in FIG. 2, the main piston 43 of the select cylinder 40 is maintained in position S _1, the main piston 23 of the shift cylinder 20 is maintained in the intermediate position NE Have been. Depress the clutch pedal in this state, by moving the shift lever to F ₁ of the shift pattern C, the select cylinder 4
The 0 electromagnetic switching valve 49 and the electromagnetic switching valve 30 of the shift cylinder 20 are excited, and compressed air is supplied to the first pressure chamber 44 of the select cylinder 40 and the second pressure chamber 25 of the shift cylinder 20. As a result, as shown in FIG. 3, the main piston 43 of the select cylinder 40 is moved to the position S _1.
Is held, and the main piston 23 of the shift cylinder 20 is moved in a direction to reduce the first pressure chamber 24, as shown in FIG. 4, it reaches a position SHA corresponding to F ₁ of the shift pattern C. When the main piston 23 of the shift cylinder 20 reaches the position SHA, it is confirmed by the position sensor, and the electromagnetic switching valves 30 and 49 are demagnetized based on the confirmation signal of the sensor, and as shown in FIG. The shift-completion state is reached in which the compressed air in the second pressure chamber 25 of 20 and the first pressure chamber 44 of the select cylinder 40 is discharged.

When the shift lever located at F _{1 of the} shift pattern C is returned to N ₁ and then turned into R ₂ via N ₂ , the following control is performed. The shift lever in the pre-operation which is located F ₁ of the shift pattern C state, the shift cylinder 20 and select cylinder 4
0, all solenoid-operated directional control valves 29, 30, 31, 49, 50,
51 is in a demagnetized state. Therefore, as shown in FIG. 5, the shift cylinder 20 and the select cylinder 4
0 all pressure chambers 24, 25, 28, 44, 45, 48
Is open to the atmosphere. From this state, depression of the clutch pedal and move the shift lever to the R ₂ of the shift pattern C, first electromagnetic switching valve 31 of the electromagnetic switching valve 49 and the shift cylinder 20 of the select cylinder 40 is excited, illustrated in FIG. 6 As described above, the first pressure chamber 44 of the select cylinder 40 and the third pressure chamber 28 of the shift cylinder 20
Is supplied with compressed air. Then, after a predetermined time t ₁ has elapsed, the electromagnetic switching valve 29 is excited, the shift cylinder 20
Compressed air is also supplied to the first pressure chamber 24. Then
As shown in FIG. 7, the main piston 23 is moved in the direction to reduce the second pressure chamber 25 by the pressure of the first pressure chamber 24, and the rod 23a of the main piston 23 is moved to the free piston position as shown in FIG. 26 and stops at the position NE. By the way, in the above control, the third pressure chamber 2
The reason why the supply of the compressed air to the first pressure chamber 24 is earlier than that of the supply of the compressed air to the first pressure chamber 24 is to apply the compressed air to the free piston 26 in advance so that the main piston 23 does not overrun beyond the position NE. This is because the pressure is increased and the stopper wall is formed by the free piston 26. In this manner, as shown in FIG.
When the position NE (N _{1 of the} shift pattern C) is reached, the position is confirmed by the position sensor, and the electromagnetic switching valves 50 and 51 are energized based on the confirmation signal of the sensor, and the second pressure chamber 45 of the select cylinder 40 and the second Compressed air is supplied to the third pressure chamber 48. Then, as shown in FIG. 9, the main piston 43 applies the pressure in the second pressure chamber 45 and the third pressure chamber 48.
By the pressure of being moved in a direction to reduce the first pressure chamber 44 is stopped at the position S _2. During this time, the electromagnetic switching valve 4
9 is in the excited state, and the electromagnetic switching valve 50
It is demagnetized after a predetermined time t ₂ after the above excited. By the way, in the above control, the reason why the compressed air is temporarily supplied to the second pressure chamber 45 is to make the movement of the main piston 43 quick. Also, during this time, that is, during the movement from N ₁ to N ₂ in the shift pattern C, as shown in FIGS. 9 and 10, the third pressure chamber 28 of the shift cylinder 20 is used.
, The duty of the electromagnetic switching valve 31 is controlled to be maintained at a low pressure. This is for the purpose of promptly performing the next shift operation, and it is preferable that the third pressure chamber 28 be maintained at the minimum pressure within a range where the main piston 23 does not move. FIG.
As shown in ( ₂ ), the main piston 43 of the select cylinder 40 is positioned at the position S ₂ (that is, N _{2 of the} shift pattern C).
Is reached, the position is confirmed by the position sensor, the electromagnetic switching valve 31 is demagnetized by the confirmation signal of the sensor, and the compressed air in the third pressure chamber 28 is discharged. At this time, the electromagnetic switching valve 29 is in an excited state. Therefore, the main piston 23 of the shift cylinder 20 is moved in a direction to reduce the second pressure chamber 25 as shown in FIG.
At this time, since the pressure in the third pressure chamber 28 is exhausted from a low pressure state, the pressure drops quickly, and therefore, the piston 23 moves quickly. During this time, that is, while moving from N ₂ to R ₂ in the shift pattern C, the selection cylinder 4
Electromagnetic switching valve 49, 51 of 0 is maintained in an energized state, the main piston 43 is held in position S _2. Then, as shown in FIG. 12, the main piston 23 moves to the position SHB.
When it reaches (ie, R _{2 of the} shift pattern C), it is confirmed by the position sensor, and the electromagnetic switching valves 29, 49, 51 are demagnetized by the confirmation signal of the sensor. Therefore, the pressure chambers 24, 44, 48 are connected to the other pressure chambers 25, 2
It is opened to the atmosphere in the same manner as 8, 45, and the shift is completed as shown in FIG. FIG. 14 is a timing chart showing the above control.

[0022] In the control of the shift cylinder 20 corresponding to the F ₁ shift turn C to N ₁ (FIG. 6, FIG. 7), so that the main piston 23 does not overrun, the third pressure chamber 28 Supply of compressed air to the first pressure chamber 24 is faster than supply of compressed air to the first pressure chamber 24. However, instead of such control, as shown in FIGS. It is also possible to temporarily excite 30 and supply compressed air to the second pressure chamber 25 temporarily so that the moving speed of the main piston 23 is suppressed by the pressure. In this case, the electromagnetic switching valves 29 and 31 can be simultaneously excited to supply compressed air to the first pressure chamber 24 and the third pressure chamber 28 at the same time.

[0023] In the above control, while corresponding to the F ₁ of the shift pattern C to N _1, the select cylinder 4
At 0, no special control is performed (FIGS. 6, 7 and 8). However, as shown in FIGS. 15 and 16, the duty of the electromagnetic switching valve 49 of the select cylinder 40 is controlled during this time. Alternatively, the first pressure chamber 44 may be set at a low pressure. At this time, the pressure in the first pressure chamber 44 is preferably maintained at a minimum pressure within a range where the main piston 43 does not move. In this way, the next operation of the select cylinder 40 can be performed quickly. Next operation, ie, shift pattern C
In the select cylinder 40 between which corresponds to from N ₁ to N _2, as shown in FIG. 17, a third pressure chamber by energizing the electromagnetic switching valve 51 while maintaining the first pressure chamber 44 to a low pressure Compressed air is supplied to the electromagnetic switching valve 4 after a certain time.
9 is released and the normal excitation is performed.
As shown in FIG. 8, compressed air of normal pressure may be supplied to the first pressure chamber 44. In this case, the main piston 43
When the first pressure chamber starts to move, the operation of the main piston 43 can be performed quickly because the first pressure chamber 44 is at a low pressure.

Next, when the shift lever located at R ₂ of the shift pattern C is turned to F ₁ via N ₂ and N ₁ , the following control is performed. In a pre-operation of the shift lever is positioned at R ₂ shift pattern C state, all of the electromagnetic switching valve 29,30,31,49,50,51 of the shift cylinder 20 and the select cylinder 40 is demagnetized is there. Therefore, as shown in FIG. 19, all the pressure chambers 24, 25, 28, 44, 45, 48 of the shift cylinder 20 and the select cylinder 40 are open to the atmosphere. From this state, depression of the clutch pedal, when turning on the shift lever to F ₁ of the shift pattern C, first, the electromagnetic switching valve 31 of the shift cylinder 20 is energized, as shown in FIG. 20, the third pressure chamber 28 Is supplied with compressed air. Then, the main piston 23 is moved in a direction to reduce the first pressure chamber 24. At this time, since the compressed air is not supplied to the first pressure chamber 24, the movement of the main piston 23 can be performed quickly. Next, after a certain time t ₃ , the electromagnetic switching valve 29 is also excited, compressed air is also supplied to the first pressure chamber 24, and the main piston 23 is stopped at the position NE as shown in FIG. Note that when the electromagnetic switching valve 29 is excited, the piston 23 is moved to the position NE.
It is preferable to make the delay as long as it does not overrun (ie, N _{2 of the} shift pattern C). On the other hand, the electromagnetic switching valve 49 of the selection cylinder 40 is energized and compressed air is being supplied to the first pressure chamber 44, and the electromagnetic switching valve 51 is subjected to the duty control to perform the third pressure chamber 48. Is maintained at a low pressure. Accordingly, as shown in FIGS. 20 and 21, the main piston 43 is maintained in position S _2. However, it is preferable to maintain the third pressure chamber 48 at the minimum pressure within a range where the main piston 43 does not move. This is to make the next select operation quickly performed. As described above, when the main piston 23 of the shift cylinder 20 reaches the position NE (that is, N _{2 of the} shift pattern C), it is confirmed by the position sensor,
According to the confirmation signal of the sensor, the select cylinder 40
Is demagnetized, and the compressed air in the third pressure chamber 48 is discharged. Therefore, the main piston 43
By the pressure of the first pressure chamber 44, as shown in FIG. 22, the second pressure chamber 45 is moved in a direction to reduce, and FIG.
Reaches the position S ₁ as shown in. At this time, the compressed air in the third pressure chamber 48 is discharged from the low pressure state, so that the pressure decreases quickly, and therefore the main piston 43 moves quickly. During this time, that is, while the main piston 43 of the select cylinder 40 moves from the position S ₂ to the position S ₁ , the electromagnetic switching valve 31 of the shift cylinder 20 is excited, and compressed air is supplied to the third pressure chamber 28. ,
The duty of the electromagnetic switching valve 29 is controlled, and the first pressure chamber 24
Is maintained at a low pressure. This is for performing the next shift operation quickly. As shown in FIG. 23, when the main piston 43 of the select cylinder 40 reaches the position S ₁ (that is, N _{1 of the} shift pattern C), it is confirmed by the position sensor, and the electromagnetic signal of the shift cylinder 20 is received by the confirmation signal of the sensor. The switching valves 29 and 31 are demagnetized,
The electromagnetic switching valve 30 is excited. Accordingly, the compressed air is supplied to the second pressure chamber 25 of the shift cylinder 20, and the pressure moves the main piston 23 in the direction of reducing the first pressure chamber 24 as shown in FIG. . At this time, the compressed air in the first pressure chamber 24 is discharged from the low pressure, so that the pressure decreases rapidly and the main piston 23
Movement is quick. And the main piston 2
When 3 reaches the position SHA (that is, F _{1 of the} shift pattern C) as shown in FIG. 25, it is confirmed by the position sensor, and the electromagnetic switching valve 30 and the electromagnetic switching valve of the select cylinder 40 are confirmed by the sensor's confirmation signal. 49 is demagnetized, and the pressure chambers 25, 44 become the other pressure chambers 24, 28, 4
Open to the atmosphere as in 5,48. FIG. 26 shows a shift completed state. FIG. 27 is a timing chart showing the above control.

The control of the shift cylinder 20 corresponding to R ₂ to N ₂ of the shift pattern C (FIG. 20,
In FIG. 21), the supply of the compressed air to the first pressure chamber 24 is delayed from the supply to the third pressure chamber 28 in order to increase the moving speed of the main piston 23. , The electromagnetic switching valves 29 and 31 are simultaneously excited, and as shown in FIG.
Compressed air is supplied to the
May be excited for a certain time to supply compressed air to the second pressure chamber 25 temporarily. The pressure in the second pressure chamber 25 at this time increases the moving speed of the main piston 23.

In the above-described control, the shift cylinder 20 is shifted during the period from N ₂ to N ₁ of the shift pattern C.
The first pressure chamber 24 is set at a low pressure (FIGS. 22 and 23) to speed up the next shift operation, that is, the movement of the main piston 23 from the position NE to the position SHA. As shown in FIG. 29, the electromagnetic switching valves 29 and 31 of the shift cylinder 20 are excited to supply compressed air to the first pressure chamber 24 and the third pressure chamber 28, and the duty of the electromagnetic switching valve 30 is controlled. The second pressure chamber 25 may be maintained at a low pressure. By doing so, the next shift operation, that is, moving the main piston 23 from the position NE to the position S
When the electromagnetic switching valves 29 and 31 are demagnetized and the electromagnetic switching valve 30 is switched from the duty control to the normal excitation in order to move to the HA, the pressure in the second pressure chamber 25 rises quickly, so that the movement of the main piston 23 is quick. Can be done.

When the shift lever located at N _{1 of the} shift pattern C is moved to F ₂ , each cylinder 20,
40 is controlled as follows. In a state where the shift lever is positioned at N ₁ of the shift pattern C, all of the electromagnetic switching valve 29,30,31,49,50,51 are demagnetized. Therefore, all the pressure chambers 24, 25, 28,
44, 45 and 48 are open to the atmosphere. Then, as shown in FIG. 30, the main piston 43 of the select cylinder 40 is maintained in position S _1, the main piston 23 of the shift cylinder 20 is maintained in position NE. Depress the clutch pedal in this state, by moving the shift lever to the F ₂ shift pattern C, is electromagnetic switching valve 51 of the select cylinder 40 is energized, compressed air is supplied to the third pressure chamber 48. Therefore, the main piston 43 is moved in a direction to reduce the first pressure chamber 44 as shown in FIG. At this time, since compressed air is not supplied to the first pressure chamber 44, the main piston 4
The movement of 3 is performed quickly. Then after a predetermined time t _4, the electromagnetic switching valve 49 is also energized, even to the first pressure chamber 44 the compressed air is supplied, as shown the main piston 43 in Figure 32, is stopped at the position S _2. The electromagnetic switching valve 4
It is preferable that the excitation timing 9 is delayed as long as the main piston 43 does not overrun at the position S ₂ (that is, N _{2 of the} shift pattern C). On the other hand, during that time, the electromagnetic switching valves 29 and 31 of the shift cylinder 20 are excited, and the first
Compressed air is supplied to the pressure chamber 24 and the third pressure chamber 28, and the electromagnetic switching valve 30 is subjected to duty control.
The second pressure chamber 25 is maintained at a low pressure. And FIG.
As shown in FIG. 1 and FIG. 32, the main piston 23 is maintained at the position NE. However, the second pressure chamber 25 is preferably maintained at a high pressure within a range where the main piston 23 does not move. This is for the purpose of promptly performing the next shift operation. As described above, the selection cylinder 40
As shown in FIG. 32, the main piston 43
₂ (that is, N _{2 of the} shift pattern C), it is confirmed by the position sensor, and the electromagnetic switching valves 29 and 31 of the shift cylinder 20 are demagnetized and the duty of the electromagnetic switching valve 30 Control is released. Therefore, as shown in FIG. 33, the compressed air in the first pressure chamber 24 and the third pressure chamber 28 of the shift cylinder 20 is discharged to the atmosphere, and the compressed air at normal pressure is supplied to the second pressure chamber 25. You. And the main piston 23
The first pressure chamber 24 is moved in a direction to reduce it. At this time,
Since the pressure in the second pressure chamber 25 has been increased in advance, the operation of the main piston 23 is quick. Thus, as shown in FIG. 34, the main piston 23 of the shift cylinder 20 is at the position SHA (that is, F _{2 of the} shift pattern C).
Is reached, the position is confirmed by the position sensor, and the electromagnetic switching valves 30 of the shift cylinder 20 and the electromagnetic switching valves 49, 51 of the select cylinder 40 are confirmed by the confirmation signal of the sensor.
Are demagnetized, and as shown in FIG.
4, 25, 28, 44, 45, 48 are open to the atmosphere. FIG. 36 is a timing chart showing the above control.

[0028] The control of the select cylinder 40 that corresponds to the N ₁ shift pattern C until N ₂ (3
In (1, FIG. 32), the supply of the compressed air to the first pressure chamber 44 is delayed from the supply to the third pressure chamber 48 in order to speed up the operation of the main piston 43, but instead of such control, As shown in FIG.
The compressed air may be supplied to the first pressure chamber 44 and the third pressure chamber 48, and the compressed air may also be supplied to the second pressure chamber 45 temporarily. By doing so, the main piston 43 of the select cylinder 40 is accelerated by the pressure of the second pressure chamber 45.

Further, control of the shift cylinder 20 corresponding to the N ₁ shift pattern C until N ₂ (3
1 and FIG. 32), a low pressure is applied to the second pressure chamber 25 in order to speed up the next shift operation.
As shown in FIG. 23, the main piston 23 may be held at the position NE while the first pressure chamber 24 is maintained at a low pressure. By doing so, the compressed air in the first pressure chamber 24 is discharged from the low pressure state at the time of the next shift operation, so that the pressure drops quickly and the main piston 23 moves quickly.

When the shift lever located at N _{3 of the} shift pattern C is moved to R ₂ , each cylinder 2
0 and 40 are controlled as follows. In a state where the shift lever is positioned at N ₃ shift pattern C, all of the electromagnetic switching valve 29,30,31,49,50,51 are demagnetized. Therefore, all the pressure chambers 24, 25, 2
8, 44, 45 and 48 are open to the atmosphere. Then, as shown in FIG. 37, the main piston 43 of the select cylinder 40 is maintained in position S _3, the main piston 23 of the shift cylinder 20 is maintained in position NE. Depress the clutch pedal in this state, by moving the shift lever to the R ₂ of the shift pattern C, the electromagnetic switching valve 51 of the select cylinder 40 is energized, Fig. 3
As shown in FIG. 8, the compressed air is supplied to the third pressure chamber 48 of the select cylinder 40. Then, for a certain time t ₅
Later, the electromagnetic switching valve 49 is excited, and the compressed air is also supplied to the first pressure chamber 44 of the select cylinder 40. Then, the main piston 43 moves to the first position as shown in FIG.
Is moved in a direction to reduce the second pressure chamber 45 by the pressure of the pressure chamber 44, as the rod 43a of the main piston 43 is shown in FIG. 40, and stops at the position S ₂ abuts against the free piston 46. In the above control, the reason why the supply of the compressed air to the third pressure chamber 48 is made earlier than the supply of the compressed air to the first pressure chamber 44 is that the main piston 4
3 so as not to overrun beyond the position S _2, by increasing the pressure on the previously free piston 46 is of to make a stopper wall by the free piston 46. On the other hand, during this time, that is, while the shift pattern C moves from N ₃ to N ₂ , the electromagnetic switching valve 29 of the shift cylinder 20 is excited, compressed air is supplied to the first pressure chamber 24, and the electromagnetic switching valve 31 is The duty is controlled and the third pressure chamber 28
Is maintained at a low pressure. Then, the main piston 23 of the shift cylinder 20 is maintained at the position NE. As described above, the main piston 4 of the select cylinder 40
When 3 reaches the position S ₂ (N _{2 of the} shift pattern C),
It is confirmed by the position sensor, and the electromagnetic switching valve 31 of the shift cylinder 20 is demagnetized by the confirmation signal of the sensor. Therefore, as shown in FIG. 41, the main piston 23 of the shift cylinder 20 is moved in a direction to reduce the second pressure chamber 25. At this time, the pressure in the third pressure chamber 28 is exhausted from a low pressure state, so that the pressure decreases rapidly, so that the piston 23 moves quickly.
Then, as shown in FIG. 42, the main piston 23
When the position reaches the position SHB (that is, R _{2 of the} shift pattern C), it is confirmed by the position sensor, and the electromagnetic switching valves 29, 49, and 51 are demagnetized by the confirmation signal of the sensor.
Therefore, the pressure chambers 24, 44, and 48 are
It is opened to the atmosphere in the same manner as 5, 28, and 45, and the shift is completed as shown in FIG. FIG. 44 is a timing chart showing the above control.

The control of the select cylinder 40 corresponding to the shift pattern C from N ₃ to N ₂ (FIG. 3)
8, FIG. 39), so that the main piston 43 does not overrun position S _2, but the supply of compressed air to the first pressure chamber 44 is delayed than the supply of compressed air to a third pressure chamber 48 Instead of such control, as shown in FIG. 45, the compressed air is simultaneously supplied to the first pressure chamber 44 and the third pressure chamber 48, and the compressed air is also temporarily supplied to the second pressure chamber 45. May be supplied. With this configuration, the acceleration of the main piston 43 is suppressed by the pressure of the second pressure chamber 45.

[0032] When the shift lever is located in the F ₂ shift pattern C is moved to R ₃ are, each cylinder 20,
40 is controlled as follows. In a state where the shift lever is positioned in the F ₂ shift pattern C, all of the electromagnetic switching valve 29,30,31,49,50,51 are demagnetized. Therefore, all the pressure chambers 24, 25, 28,
44, 45 and 48 are open to the atmosphere. Then, as shown in FIG. 46, the main piston 23 of the shift cylinder 20 is maintained in position SHA, the main piston 43 of the select cylinder 40 is maintained in the position S _2. Depress the clutch pedal in this state, by moving the shift lever into R ₃ of the shift pattern C, the electromagnetic switching valve 31 of the shift cylinder 20 is energized, as shown in FIG. 47, compressed to a third pressure chamber 28 Air is supplied. Next, after a lapse of a predetermined time t ₆ , the electromagnetic switching valve 29 is excited, and the compressed air is also supplied to the first pressure chamber 24.
Then, the main piston 23 of the shift cylinder 20
Is moved in a direction to reduce the second pressure chamber 25 by the pressure of the first pressure chamber 24 as shown in FIG. 48, and the rod 23a of the main piston 23 is moved as shown in FIG.
It comes into contact with the free piston 26 and stops at the position NE. In the above control, the reason why the supply of the compressed air to the third pressure chamber 28 is made earlier than the supply of the compressed air to the first pressure chamber 24 is that the main piston 23 does not overrun at the position NE. Then, the pressure applied to the free piston 26 is increased in advance, and the stopper wall is formed by the free piston 26. During this time, i.e. during the movement from the F ₂ shift pattern C until N _2, the select cylinder 40, the electromagnetic switching valve 51 is energized, compressed air is supplied to the third pressure chamber 48, and the electromagnetic switching valve 49 Duty control is performed, the first pressure chamber 44 is maintained at a low pressure,
The main piston 43 is maintained in position S _2. The reason why the first pressure chamber 44 is maintained at a low pressure is to promptly perform the next select operation. As mentioned above,
When the main piston 23 of the shift cylinder 20 is in the position NE
Is reached, the position is confirmed by the position sensor, and the electromagnetic switching valve 31 is switched to the duty control by the confirmation signal of the sensor. The electromagnetic switching valves 49 and 51 of the select cylinder 40 are demagnetized, and the electromagnetic switching valve 50 is excited. Therefore, as shown in FIG. 50, the main piston 43 of the select cylinder 40 is
Is moved in the direction to reduce. At this time, the first pressure chamber 44
Is exhausted from the low pressure state, the resistance to the main piston 43 is small, and the main piston 43 is moved quickly. Then, the main piston 43 is moved as shown in FIG.
As shown in ( ₂ ), when the position S ₃ (that is, N _{3 of the} shift pattern C) is reached, it is confirmed by the position sensor, and the electromagnetic switching valve 31 of the shift cylinder 20 is demagnetized by the confirmation signal of the sensor. Therefore, the main piston 23 of the shift cylinder 20 is moved by the pressure of the first pressure chamber 24 in the direction of reducing the second pressure chamber 25 as shown in FIG. At this time, since the pressure in the third pressure chamber 28 is exhausted from a low pressure state, the pressure decreases quickly, and therefore, the movement of the main piston 23 is performed quickly. When the main piston 23 reaches the position SHB as shown in FIG. 53, it is confirmed by the position sensor, and the electromagnetic switching valves 29, 5 are confirmed by the confirmation signal of the sensor.
0 is demagnetized. Therefore, the pressure chambers 24 and 45 are opened to the atmosphere similarly to the other pressure chambers 25, 28, 44 and 48, and the shift is completed as shown in FIG. FIG. 55 is a timing chart showing the above control.

The control of the shift cylinder 20 corresponding to the shift pattern C from F ₂ to N ₂ (FIG. 4)
7, 7, 48), the supply of the compressed air to the first pressure chamber 24 is delayed from the supply of the compressed air to the third pressure chamber 28 so that the main piston 23 does not overrun at the position NE. Instead of such control, as shown in FIG. 15, while simultaneously supplying compressed air to the first pressure chamber 24 and the third pressure chamber 28, compressed air is also temporarily supplied to the second pressure chamber 25. May be supplied. With this configuration, the acceleration of the main piston 23 is suppressed by the pressure of the second pressure chamber 25.

The control of the select cylinder 40 corresponding to the shift pattern C from F ₂ to N ₂ (FIG. 4)
7, FIG. 48 and FIG. 49), the select cylinder 40
Although the first pressure chamber 44 is maintained at a low pressure in order to quickly perform the next operation, the control is replaced with the first pressure chamber 44 and the third pressure chamber 44 as shown in FIG. Pressure chamber 48
May be maintained at normal pressure, and the second pressure chamber 45 may be maintained at a low pressure by duty-controlling the electromagnetic switching valve 50. By doing so, the second select operation is performed by the second select operation.
The pressure in the pressure chamber 45 rises faster, and the starting of the main piston 43 also gets faster.

In the above, the shift lever is shifted to the shift pattern C.
From N ₁ to F _1, from F ₁ to R _2, F ₁ from R ₂
, N ₁ to F ₂ , N ₃ to R ₂ , and F
Has been described control when operating from ₂ to R _3, by appropriately applying the control also for other operations, the shift cylinder 20 and speed or the main piston 23 of the select cylinder 40,
43 can be prevented.
