Description

[Detailed Description of the Invention] The present invention relates to a power clutch operation device for a vehicle.When the engine is left running to drive an air conditioner or the like while the vehicle is stationary, the clutch remains connected. The rotation of the engine is transmitted to the subshaft of the transmission. In such a state, the gear on the countershaft and the gear on the main shaft that mesh with it produce a whirring noise, which can be a nuisance when taking a nap at the middle of the rack. becomes.

Conventionally, a power clutch operating device has been proposed that is equipped with a function to prevent rattling noise of the transmission (to maintain the clutch in the disengaged state).

However, in the conventional system, a bypass was installed on the switching piece that controlled the 11x horn device. In addition to having to pull the trap 1, when the bypass circuit is activated, the first
As shown in the figure 1, sea urchin, sap] ■-ta A screw: ~n 1
4 is moved by the piston rod 13 of the air-juice acticoator B, so the liquid-juice operating chamber 40 becomes under negative pressure.
There is a possibility that air may enter the working chamber 40 from the outside.

Further, the hydraulic actuator A's histograms 1 to 14 move to the full stroke of the pneumatic actuator B. Also, if the clutch pedal is depressed while the bypass circuit is in the conductive state, piston 1 of the liquid actuator A
4 may miss the A-purse 1~○-.

When performing normal clutch operation with the bypass circuit disconnected from the conductive state, be sure to check the air ff: -7'Cut: I-actuator and hydraulic actuator pressure]-
If you do not operate the clutch pedal after the engine has fully returned,
There are deficiencies such as the inability to perform correct EA operations.

It is an object of the present invention to provide a power clutch operation device for both Φ and Φ that eliminates such problems.

For this reason, the configuration of the present invention is such that the hydraulic pressure for operating the clutch is
Screw 1 of the cut yuator has a shaft hole Ill, and the shaft hole has a head whose one end surface abuts against the clutch operating rod and whose other end surface abuts against the screws 1 to 1. The tip of the rod abuts against a fluid actuating stone actuated in connection with clutch operation, thereby causing actuation of the fluid actuator I//f-j. It is designed to block out clasping and make it 10 times stronger.

To explain the present invention with reference to an embodiment, as shown in FIG. It's empty. Hydraulic actuator: +[-ta is a screw] Fit the hem 14 inside the cylinder 17, and form the entire structure on the left end side, as well as insert a cylinder into the inside of the air hole on the right end side. A return spring 16 interposed between the cylinder 14 and the end wall of the cylinder 17 is accommodated.Liquid I3: The working chamber of the mask cylinder A is supplied with hydraulic pressure from the mask cylinder HM7 through a conduit 8. It is designed to be supplied via route #120.

The mask cylinder Mli! Reference numeral 17 indicates a device for forcefully feeding the liquid filled in this left end chamber from the liquid tank 4 to the conduit 8 by screws 1 to 6 fitted inside the cylinder 5 (there is one, and the piston 6 is moved to the middle rest side with the support shaft 38). It is supported and operated by the I-clutch pedal 2.

Fluid pressure acticoator B is 1flI acticoator A
Vinton 10JE: is arranged on the same axis as the cylinders 1 and 5, and the working chamber 11 is partitioned off on the left end side, and the holding pressure chamber 9 is partitioned off on the right side.
A spring 12 is installed between the cylinder 15 and the right end wall of the cylinder 15. Then, on the wall that partitions the cylinder 15 and the cylinder 17, a single rod 13 is slidably supported.
One end of this passes through the piston 10, and the other end passes through the piston 14! , and large (the yen part 13a is abutted against the right end surface of the screw 1-ne 14).

The rod 18 is engaged with the recess in the large diameter portion 13a, and the rod 18 is operated from the right end number IM'@19.
connected to.

The control valve C is connected to the above-mentioned passage 20 and includes a cylinder into which the screws 1 to 21 are fitted, and a chamber 23 and a chamber 26 partitioned by a dianoram 25 are provided roughly on the right end side of the cylinder. A hole 29 is formed on the right side of the hole 26 and is closed by a valve body 27 which receives the force of a spring, and an air pressure inlet 28 is provided in this chamber 29.

A hollow valve body 22 is supported by the diaphragm 25, and a rod protruding from the valve body 25 by a spring is abutted against the screws 1 to 21 described above. Then, the chamber 23 is dissolved into the inviting atmosphere through the passage 24, and all 26 and 29
One of the two is selectively connected to the conduit 35 via an electromagnetic on-off valve 31°5-32. This guide @′
The ends of 35 are connected to all 1'1 of air perspiration actuators B. Solenoid valve 31, 321; II, /I exchange switch 3
When one side is energized from 11 [1133] by 4,
Open the valve ('': consists of sea urchins.

In addition, the end wall 36 of the hydraulic actuator A (this is screwed together with the cylindrical stud 1 to the collar 37 h and fixed by a nut 38).
Regarding the 50-degree control valve C, it is almost four balls compared to the conventional example.

Next, I invented one! To explain the operation of +[, in normal operation, that is, in operation while the vehicle is running, when the clutch pedal 2 is depressed, pressure fluid flows from the mask cylinder device 1f7 through the sound guide 8 and the passage 20 to the left end of the hydraulic actuator A. The piston 14 moves to the right, and the clutch operating portion 19 coupled to each rod 18 with the head 13a is pushed to the right, and the clutch is disengaged.

At the same time, the piston 2] is moved to the right by the pressure fluid in the passage 200, and the valve body 22 abuts against the valve body 27.

6- (Against L, the dianolumn 25 and the valve body 27 move in the direction of I. Therefore, ff condensed air enters the chamber 29 from the inlet 28 and enters the chamber 26, from which the command is heard. When the electromagnetic on-off valve 31 and the conductor 35 are in the closed state, air enters the working chamber 1'1/\ of the rotor.

Press 1 to 10 to the right against spring 12.
, this force is transmitted through the rod 13 to the rod 18.

In this way, the clutch operating portion 191 is operated by the clutch pedal 2, the operating horn of the clutch pedal 2, the operating horn of the 1-ta A, and the operating force of the 1-ta B. Join me, I! I can release the clutch comfortably - (
I can do it.

When the clutch pedal 2 is released, the pedal 2 is returned to its original position by a spring (not shown), and the liquid juice actuator is released.
The screw 14 is returned together with the rod 13 by the force of the spring 16.

Also, since the hydraulic pressure acting on the screw 21 in the control valve C is released, the spring force returns the valve 27 and shuts off the chamber 26 and g29. Since the body 22 is returned and separated from the valve body 27, the seedling 26 is released after passing through the first passage 24, all 23, and the U valve body 22, so that the pneumatic actuator: I ■ - Ta B all 1
1 is released, and the spring 12 causes the screw 10 to be released.
is returned.

Next, to take a nap, set the switch to -J and disengage the clutch.
Switch to 4 and GJ is good. When the solenoid valve 22 or 11
41, compressed air is supplied from the inlet 28 to the chamber 111 through the chamber 29, the electromagnetic on-off valve 32 and the conduit 35. The rod 13 is pushed to the right by the screws 1 to 10, and stops when the end 13a hits the collar 37. At the same time, the clutch operating portion 19 is pushed to the right by one push 18, and the clutch is disengaged.

At this time, the screw I-14 of the liquid J't actuator A
is left behind and the conventional example is 6 by the sea urchin rod 13.
Since it will not be pushed down, the pressure in the leftmost liquid chamber will not reach i; therefore, there is no risk of air being sucked in from the outside.

Also, if the clutch pedal 2 is unnecessarily depressed at this time, the piston 14/me will move to the right, and the control valve C will open the valve. The body 22.27 moves in six directions, but the electromagnetic on-off valve 3 remains closed, so the fluid pressure j2 -ta Bl
, the mtMi on-off valve 332 is turned on, and the rice air is supplied, and there is no change in the operating state of the clutch.

For this reason, the switching operation of the electromagnetic on-off valves 31 and 32 can be performed even when the clutch pedal 10 is depressed.

Or (even in the fully released state, the 'ti magnetic on-off on-off valve 32
4-If the clutch is opened, the clutch will be maintained in a disengaged state, and there will be no adverse effects.

Since the present invention is configured as described above, the hydraulic actuator]
Related to the operation of Neeta A's screws 1 to 1, - Control valve C
By forming a bypass circuit (1, 2, ゛), the air actuator B can be activated and the clutch can be kept in the disengaged state, and J, as explained at the beginning. It is possible to eliminate the drawbacks of the conventional example, and it is also possible to eliminate the noise of the transmission caused by engine operation while the engine is stopped.
, ::The effect is j9.
