Hydraulic control valve of the hydraulic clutch.
According to the present invention, in the clutch which transmits or blocks the rotational force of the engine to the driving wheel, the oil is supplied to the release cylinder by controlling the hydraulic pressure of the master cylinder to control the clutch by operating only the shift lever in accordance with the speed without the clutch pedal. In order to provide a semi-auto clutch that can improve the convenience of driving by intermittently clutching.
The clutch is installed between the engine and the transmission to transmit or block the rotational force of the engine to the driving wheels. The clutch must be in a no-load state when starting the engine, and the engine power must be temporarily cut off for the inertia operation of the vehicle. It is to make the shifting easier by blocking the.
In a conventional vehicle equipped with a manual transmission, the frequency of use of the clutch is relatively low at high speeds, so the fatigue of the knees and ankles is relatively low.However, when driving a car for a long time due to the current complicated road conditions and frequent changing traffic lights, The gears need to be changed from time to time, causing fatigue on the knees and ankles. Also, when the clutch is released after the power is cut off, the clutch should be released slowly. In other words, because the clutch pedal is put in a hurry, the hydraulic pressure supplied to the hole cylinder is suddenly directed to the master cylinder, so power transmission is not smooth and the vehicle suddenly exits.
Due to these drawbacks, vehicles with automatic transmissions tend to be preferred in recent years, but vehicles with automatic transmissions are relatively more expensive than manual transmissions, and incur a high cost of repairs in case of breakdown. Many problems with the momentary acceleration is low, the driver has a shortcoming in the ability to cope quickly depending on the situation.
Recently, the global trend is that many vehicles are shipped with semi-auto clutches on light vehicles, and there are also companies that develop or sell semi-auto clutches for after-market marquees that can be installed on vehicles already shipped. It is a fact.
However, the semi-auto clutch as described above is a situation that cannot be popularized because the additional mounting is complicated or coarse, so that the bad factors are large, the side effects are large, and the mounting cost is expensive.
In order to compensate for the above disadvantages, the clutch pedal of the manual transmission vehicle has been proposed to clamp the clutch by pushing the master cylinder by pulling the clutch pedal by a vacuum operation device, which is a clutch operation device. It is a method that pushes the master cylinder by pulling the clutch pedal by vacuum pressure by connecting the flexible hose to the vacuum booster rather than pushing the master cylinder to clamp the clutch, so the vacuum pressure of the vacuum booster must be relatively large. After pulling the clutch pedal under vacuum pressure, the clutch is clamped while the master cylinder is pushed, so there is a closed end that causes malfunction during operation.
In addition, since the vacuum booster generating the vacuum pressure must generate a large vacuum pressure, the volume of the vacuum booster must be relatively large, so that it is relatively difficult to install the vacuum booster in the engine room. There is a downside to the overall price increase.
The present invention has been made to solve the above-mentioned conventional problems, an object of the present invention is to control the oil pressure of the release cylinder to control the hydraulic pressure of the master cylinder to control the clutch by operating only the shift lever according to the speed without the operation of the clutch pedal It is to provide an auto clutch that can provide a stable driving can be improved as well as to improve the convenience of driving by supplying the clutch.
In order to achieve the above object, the present invention installs a worm wheel and a worm torsion gear in engagement with a worm gear of a drive motor, and a multi-threaded screw is formed on the inner side of the worm torsion gear, and the outer surface is engaged with the worm torsion gear. The torsion gear was formed to control the master cylinder by reciprocating along the inner circumferential surface of the multi-screw screw without a friction coefficient.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. First, in describing each of the drawings, the same components have the same reference numerals as much as possible even though they are shown in different drawings.
As shown in FIG. 1 to FIG. 4, the configuration of the present invention forms the worm gear 6 in the drive motor M mounted in the gear housing 22, thereby coaxially forming the worm torsion gear 8. The worm wheel (2) installed in the interlocking operation is interlocked, and the worm torsion gear (8) is engaged with the torsion gear (10) having a multi-screw screw (4) formed on the inner end side of the screw gear without friction coefficient (14) ) Is to control the master cylinder 20 while reciprocating along the inner circumferential surface of the multi-threaded screw (4).
In the axial direction of the screw gear 14 reciprocating along the inner circumferential surface of the multi-threaded screw (4) is formed long the output shaft 24 for pressing the master cylinder 20, the other side is formed with a guide 26 The guide 26 is inserted into the cylindrical guide tube 30 in which the guide groove 28 is formed so that the screw gear 14 reciprocates without being rotated.
In addition, the lower end of the cylindrical guide tube 30 is formed to control the master cylinder 20 by adjusting the tension of the screw gear 14 by forming an adjustment screw.
The worm torsion gear (8) is installed on both sides of the worm torsion gear (8) by inserting the bearing (40) so that the outer surface of the bearing (40) is in contact with the gear housing (22). It prevents the worm torsion gear 8 from rubbing against the gear housing 22 during rotation to smooth the rotation.
The upper and lower surfaces of the torsion gear 8 are provided with a bearing 40a to mount the torsion gear 10 so that the outer surface of the bearing 40a is in close contact with the gear housing 22 to smoothly rotate the torsion gear 10. Of course, according to the rotation of the torsion gear 10, the screw gear 14 is to cause the reciprocating rotational movement on the inner end side.
The present invention configured as described above will be described in detail. When the present invention is installed in an automatic clutch control system operated according to a change in RPM and speed, power is applied to a vehicle, and power is supplied to the motor M mounted on the gear housing 22. Since the motor (M) is rotated by this power supply, the motor shaft, that is, the worm gear (6) is rotated.
The worm wheel 2 engaged with the worm gear 6 is rotated by the rotation of the worm gear 6, and the worm torsion gear 8 formed at its coaxial shaft is rotated according to the rotation of the worm wheel 2, and the torsion gear 10 is rotated. The screw gear 14 screwed to the multi-threaded screw 4 formed on the inner end side is rotated at a constant speed ratio to move.
As the output shaft 24 is moved by the movement of the screw gear 14, as shown in FIG. 3, the master cylinder 20 is pressurized in one direction, so that hydraulic pressure is generated in the master cylinder 20 to release the cylinder (not shown). The gear is blocked by supplying hydraulic pressure to the clutch, so the gear is shifted.
At this time, since the lower end of the screw gear 14 comes into contact with the switch when the screw gear 14 reaches a predetermined position, there is no closed end that is overloaded because the power of the motor M is cut off. Otherwise, after a predetermined time, the motor (M) rotates in reverse to move the screw gear 14 in the opposite direction, so that the gear (M), the gear, and the clutch disc can be easily shifted without any phenomenon that the motor M, the gear, and the clutch disk are worn out quickly. will be.
Therefore, the motor is operated according to the rise of the R.P.M and the change of the speed, and the clutch is clamped, so the gear shift can be precisely performed. Therefore, the manual transmission vehicle can be driven like an automatic car.
As described above, the auto clutch of the present invention can be installed regardless of the vehicle type without the need for a vacuum power supply device as in the prior art, and since the operation of the clutch pedal is mechanically processed, it is very effective for beginners and can safely drive. It will also help to prevent traffic accidents, and can only drive axel pedals without stepping on the clutch pedal, thus reducing fuel consumption and reducing the tiredness of commercial vehicle drivers who are driving professionally for a long time, such as driving a commercial taxi.
