Next, a description will be given of a gear change operation of an automatic transmission mounted on the automobile and combined with the hydraulic torque converter using the gear change lever unit 10 configured as described above.

In that automatic transmission, the oil pump is connected to the clutch, low servo, and.

The hydraulic control circuit connected to the reverse servo and
Regulator valve, throttle valve, governor
valve, shift valve, down shift valve (low range valve: range control valve), solenoid with a solenoid coil electrically connected to the select switch 25 of the gear change lever unit 10.・Up shift solenoid whose solenoid coil is electrically connected to the up shift switch 23 of the selector valve (solenoid control valve: manual valve) and its gear change lever unit 10. valve, its gear change lever unit 10 downshift
Since the switch 24 is equipped with a down shift solenoid valve etc. in which a solenoid coil is electrically connected, in the lever release mechanism 20, the release pin 51 gold finger is pressed against the return spring 52. through its plunger 48 and connecting rod 49 to push down its slide block 46 against its lever select lock spring 19.

Thus, as the slide block 46 is pushed down into the hollow rod 35 of the gear change lever 16, the lever select lock pin 18 is also formed in the hollow rod 35. The lever select lock pin 18 is moved downward in the axial direction of the gear change lever 16 into the display glass 33 of the gear change lever box 11. corresponding to the neutral position (N) displayed in the select cam plate 17, as shown in FIG.
9, the step that is the neutral position (N) is on surface 4.
1, and at that time, the lever hold guide pin 22 is engaged with the notch step 55 of the lever hold cam plate 21, so the gear, change lever 16 is only allowed to swing back and forth around its select shaft 15.

Therefore, with the release pin 51 pressed, the gear change lever 16 is swung rearward around the select shaft 15, and the gear change lever 16 is moved to the drive position of the display glass 33. (D) No, then release the finger from the release pin 51.

As such, when the finger is released from the release pin 51, the lever select lock spring 19 causes the lever select lock pin 18 to
While being guided by the thrower (44.45) formed in the hollow rod 35 of the gear change lever 16, it moves upwardly in the axial direction of the gear change lever 16 along with the slide block 46. The lever select lock pin 18 corresponds to the drive position fil (D) displayed on the display glass 33, and the select cam lock pin 18 corresponds to the drive position fil (D) displayed on the display glass 33, as shown in FIG.
At the cam hole 39 of the plate 17, the drive position (D
) is interlocked with surface 42.

As such, when the gear change lever 16 is locked in the drive position (D), the select switch 25 is switched, and the hydraulic control circuit is activated depending on the amount of depression of the accelerator pedal and the vehicle speed. , automatically shifts its transmission.

Next, press the release pin 51 with your finger again against the return spring 52 to release the plunger 48.
and its slide block 4 via a connecting rod 49
Push G down again against its lever select lock spring 19.

As such, the slide block 46
As the gear change lever 16 is pushed downward again into the hollow rod 35, its lever select lock pin 18 is again pushed down into the gear change lever 16.
The slot 44,45 formed in the hollow rod 35 of
in the axial direction of the gear change lever 16.

and the lever select lock pin 18 is in the drive position CD shown on the display glass 33 of the gear change lever box 11).
Correspondingly, as shown in FIG. 1, in the cam hole 39 of the select cam plate 17, the step in the drive position (D) is disengaged from the surface 42, and at that time, the lever - Since the hold guide pin 22 is engaged with the notch step 55 of the lever hold cam plate 21, the gear change lever 16 can only move forward and backward around the select shaft 15. It is made swingable.

Therefore, with the release pin 51 pressed, the gear change lever 16 is swung backward around the select shaft 15, and the gear change lever 16 is moved to the hold position of the display glass 33. (HOL
D) None, then release the release pin 51.

As such, when the finger is released from the release pin 51, the lever select lock spring 19 causes the lever select lock pin 18 to
While being guided by the slot 44.45 formed in the hollow rod 35 of the gear change lever 16, it moves upward in the axial direction of the gear change lever 1G along with the slide block 46. The lever select lock pin 18 corresponds to the hold position (HOLD) displayed on the display glass 33, and as shown in FIG. At the hold position (
HOLD) is engaged with surface 43.

Thus, when the gear change lever 16 is locked in the hold position (HOLD), the select
When the switch 25 is switched, the lever hold guide pin 22 is engaged with the cutout step 56 of the lever hold cam plate 21, so that the gear change lever 16 is , is swingable about its shift shaft 13 through its upshift and downshift switching plate 14, and allows manual upshifting and downshifting of the transmission.

5, the gear change lever 16 rotates clockwise around the shift shaft 13 via the switching plate 14 while resisting one of the return springs 26, 26. , the up shift switch 23 connects to the base 12 and is closed.

As such, when the up-shift switch 23 is closed, current flows through the solenoid coil of the up-shift solenoid valve, opening the up-shift solenoid valve and causing the pressure oil to flow. That oil
It flows from the pump to the clutch, whose transmission is manually upshifted.

Also, in FIG. 5, the gear change lever 16 rotates counterclockwise around the shift shaft 13 via the switching brake 14 while resisting the other of the return springs 26 and 26. If rocked, the up shift switch 23 is closed and the up shift solenoid valve is closed accordingly, while the down shift switch 24 contacts the base 12. The downshift solenoid valve's solenoid coil is energized.

As such, when current flows through that down-shift solenoid valve, that down-shift solenoid valve
The valve is opened, pressure oil flows from the oil-pump to the clutch and low servo, and the transmission is manually downshifted.

Therefore, when the vehicle is traveling on a slope, the gear change lever 16 is swung around the shift shaft 13 via the switching plate 14 in the HOLD position. The transmission can now be changed manually, allowing the vehicle to run smoothly on the slope according to the driver's will.

Also, the gear change lever 16 is swung in the H direction around the select shaft 15, and the gear change lever 16 is swung in the H direction around the select shaft 15.
The step in the cam hole of the select cam plate 17 shown in FIG. 1 corresponding to the reverse position (R) displayed on the display glass of the change lever box 11 should be engaged with the surface. If so, the select switch 25 is toggled, the solenoid select valve is operated, and pressure oil flows from the oil pump to the reverse servo, shifting the transmission into reverse gear.
