The present invention relates to a clutch control system for an automobile, and more particularly, to a clutch control system for an automobile that can smoothly and quickly transmit power and increase stability without deteriorating clutch operating force.

In general, the clutch of the vehicle is installed between the engine and the transmission to control the rotational force of the engine transmitted to the power transmission device.

These clutches must be smooth in operation, securely controlled, and easy to operate.

And the equilibrium of the rotating part should be good, the rotational inertia should be small, the heat dissipation should not be well overheated, of course, the structure should be simple, easy to handle and less trouble.

The clutch is used with friction clutch which transmits power by friction between solids, torque converter in automatic transmission, and fluid clutch using oil as a medium of power transmission, and magnetic particle is inserted between driving side and driven side. Magnetized by coils, the magnetic force of the electromagnet is automatically classified according to the number of engine revolutions.

This clutch device is composed of a clutch body and a clutch control.

The clutch body is composed of a clutch disk that transmits engine power to the transmission and a pressure plate that closely adheres the clutch disk to the flywheel. When the clutch pedal is pressed, the hydraulic pressure of the master cylinder actuates the clutch booster. Is to cut off the power from the flywheel.

In other words, when the clutch booster is activated, the release fork rotates, and this rotation moves the release bearing horizontally to push the lower part of the release lever.In response, the release lever revolves by pressing the pressure plate while retracting the pressure plate while rotating the pin at the point. When the pressure plate is retracted, the disk is separated from the fly wheel and power is cut off.

The clutch device of this configuration requires a lot of additional parts because the clutch oil is used, and since the actuation force is formed in proportion to the stepping force of the clutch pedal, a lot of force is required for the pedal operation, and when the oil leaks, the actuation force is deteriorated. There is a flaw in stability, in particular, there is a problem that the power connection is not smooth.

The present invention is invented to solve the problems of the prior art as described above, an object of the present invention is to provide a clutch control system of a vehicle with high power transmission smooth and fast, high clutch stability without deterioration of clutch operation force.

In order to achieve the above object, the present invention provides a control valve for elevating or blocking the pneumatic pressure in the pneumatic tank by elevating the supply valve in accordance with the operation of the clutch pedal, and in the pneumatic tank by elevating in accordance with the inflow or blocking of the pneumatic pressure. A relay valve which passes or blocks pneumatics, a booster whose piston moves forward or backward by passing or blocking the pneumatic pressure, and the pressure plate moves forward and backward by rotating the release lever by horizontally moving the release bearing by the piston action of the booster and the booster. Thus, the disk is composed of a clutch main body which comes off or in close contact with the fly wheel to provide a clutch control system for the vehicle, characterized in that the power of the engine is interrupted.

Is connected to the second pneumatic line (5) via a control valve (4).

The relay valve 2 is connected to the booster 7 by a third pneumatic line 6, and the booster 7 is connected to the clutch body 8.

2 is a side cross-sectional view of the control valve 4 of the present invention, wherein the pedal 9 is hinged to the cover 11 of the valve body 10, and two spring sheets ( 12) 12 'are provided with a spring 13 in the ball.

On the spring sheet 12 ', a plunger 15 which is pushed and lifted by the pushbutton 14 provided on the pedal 9 is located.

The lower end of the push rod 16 installed through the spring sheet 12, 12 'is provided in contact with a discharge valve 18 which is installed with a return spring 17. This discharge valve 18 The lower end of the spring 19 is spaced apart from the upper end of the supply valve 20, which is supported by a predetermined distance.

The valve body 10 has a port 21 communicating with the pneumatic tank 1 and a port 22 communicating with the relay valve 2.

In this configuration, when the pedal 9 is stepped on, the push rod 16 descends to lower the discharge valve 18, and the discharge valve 18 descends to supply the port 20 to the port 21. The pneumatic pressure is discharged to the port 22 through the passage (23).

3 is a side cross-sectional view of the relay valve 2 of the present invention, and a port 25 connected to the control valve 4 is opened at an upper end of the valve body 24 to communicate with the pressure chamber 26.

The diaphragm 27 is located in the pressure chamber 26, and the upper end of the elevating rod 28 is coupled to the diaphragm 27 and is provided with an elastic member 29.

A plug 31 having a port 30 connected to the pneumatic tank 1 is screwed into the lower side of the elevating rod 28, and a valve seal is formed in the space 33 through which the exhaust passage 32 is drilled. 34 is provided with the elastic member 35 in the shot.

In addition, another space portion 37 is formed on the space portion 33 and has a port 36 connected to the booster 7 and is in communication with each other.

By such a configuration, the pneumatic pressure flowing into the port 30 flows out through the valve seal 34 into the space 37 and flows out into the port 36.

When the pneumatic pressure flows into the port 25, the diaphragm 27 is pushed down by the pressure, and the lifting rod 28 is lowered accordingly, and the lower end thereof contacts the upper surface of the valve seal 34 to allow the port 30 to flow. Pneumatic pressure entering the system is shut off.

4 is a cross-sectional side view of the clutch main body 8 of the present invention, the housing 39 is fixedly coupled to the flywheel 38 to rotate together, and the release lever 40 is pin 41 to the housing 39. Hinged together. The release lever 40 is connected to the pressure plate 42, and the other side of the pressure plate 42 is connected to the bolt 44 supported by the spring 43.

In addition, one end of the release fork 47 is connected to the outer circumference of the clutch shaft 45 so that the release bearing 46 is slidably coupled to the booster 7. It is in contact with the lower stage.

Reference numeral 48 in the drawing represents a disk.

In the clutch adjustment system of the present invention configured as described above, when the pedal 9 is pressed in FIG. 2, the push rod 16 descends, and the discharge valve 18 is pushed down as the push rod 16 descends. The supply valve 20 is lowered.

When the supply valve 20 is lowered, the passage 23 is opened so that the pneumatic pressure flowing into the port 21 from the pneumatic tank 1 exits to the port 22 through the passage 23.

The air pressure flowing out through the port 22 flows into the port 25 of the relay valve 2 shown in FIG.

Then, the pressure in the pressure chamber 26 rises and pushes the diaphragm 27. As a result, the diaphragm 27 is lowered while the elastic member 29 is compressed.

As the diaphragm 27 is lowered, the lifting rod 28 coupled thereto is lowered to press the valve seal 34 to close the port 30 flowing from the pneumatic tank 1.

In this case, since the pneumatic pressure does not flow in the third pneumatic line 6 in FIG. 1, the booster 7 is reversed in FIG. 4.

In this way, when the booster 7 moves backward, the release fork 47 rotates clockwise to fall from the release bearing 46.

Then, the bolt 44 is retracted by the elastic force of the spring 43, and as the pressure plate 42 coupled thereto is retracted, the release lever 40 rotates about the pin 41 while the release bearing 46 is rotated. In this state, the disk 48 falls to the fly wheel 38 and power is cut off.

Although the above has described the action that the power is cut off, on the contrary, when the pedal 9 is released, the above action and the reverse action occur, and the port 30 and the port 36 of the relay valve 2 are shown in FIG. ) Is communicated so that the pneumatic pressure of the pneumatic tank (1) enters the booster (7).

The release fork 47 then pushes the release bearing 46 as it rotates counterclockwise, and the release bearing 46 pushes the release lever 40 so that the pressure plate 42 moves to the left as seen in FIG. By moving, the disk 48 is in close contact with the fly wheel 38 to transmit power.

As described above, the clutch control system of the present invention is powered when the air is supplied to the booster is cut off when the power is connected and discharged, so the power connection is smooth, the power cut is quick, and the pedal is easy to operate because it is operated according to the degree of pedaling, Even when the air leaks, since the supply of air from the compressor continues, the clutch operating force is not lowered and safety is high.
