Description

Clutch operate apparatus for vehicle

The present invention relates to a clutch operating device for a vehicle, and more particularly, to a clutch operating device for a vehicle to facilitate the blocking and connection of the clutch through a push operation of the button.

In general, the use of a conventional manual transmission to reduce the transmission cost and fuel cost, while the semi-automatic transmission that does not need to step on the clutch pedal, such as an automatic transmission has been gradually expanded.

On the other hand, the above-mentioned clutch Clutch refers to a mechanical element having a function of transmitting or interrupting power by mechanical contact from the driving side on the concentric shaft to the driven side. Such a clutch is installed between the engine and the transmission.

The above-mentioned clutch performs a power transmission function for transmitting the engine's rotational force to the transmission and a power cut function for temporarily shutting off the power flow between the engine and the transmission when necessary, enabling a smooth and vibration-free oscillation, It protects the overdrive power train from overload, as well as reduces the rotational vibration of the engine with the flywheel. The following describes a typical automotive clutch system.

1 is a cross-sectional view showing a conventional clutch device for a vehicle.

As shown in FIG. 1, the conventional clutch device 10 for a vehicle includes a clutch pedal 14 for controlling the clutch 12, a master cylinder 16 transmitting a force of the clutch pedal 14, and a master cylinder ( 16 is boosted by the pneumatic pump 18 for supplying air pressure through the valve hole 18a opened by hydraulic pressure, the clutch booster 20 for boosting the air pressure supplied from the pneumatic pump 18, and the clutch booster 20. It consists of a release cylinder 22 which operates the clutch 12 by pressure and a shift lever 24 which is hinged and connects the release cylinder 22 and the clutch 12. At this time, the push rod 22a of the release cylinder 22 has a return force by the return spring 26.

In the conventional clutch device for automobiles configured as described above, when the driver presses the clutch pedal 14, the piston 16a of the master cylinder 16 is actuated by the force to generate oil pressure, and the generated oil pressure is a valve hole. By opening 18a, the air pressure generated by the pneumatic pump 18 flows into the clutch booster 20 through the valve hole 18a. At this time, the air pressure generated by the pneumatic pump 18 is introduced into the clutch booster 20 via the pneumatic induction pipe 18b, and the introduced air pressure moves the clutch booster piston 20a to move the release cylinder 22. The push rod 22a is moved, and by the movement of the push rod 22a, the shift lever 24 separates the clutch disc from the drive plate of the engine and cuts off power transmitted to the flywheel.

However, the manual clutch device as described above has a problem in that an overwhelming force occurs in the ankle or knee when the vehicle is driven for a long time because the driver has to give a greater force than the small vehicle when the driver presses the clutch pedal.

In addition, even in small vehicles, in order to prevent the vehicle from starting off during long periods of congestion and slowness, or when driving in the city, when you release the clutch pedal, you need to step on the accelerator pedal while moving the foot finely in the half-clutch section. There is a problem that it is easy to get tired and get tired easily.

In addition, in order to flexibly maintain the operation of the clutch pedal, complicated components are required as described above.

Moreover, when the left foot is unnaturally disabled, there is a problem in that the vehicle equipped with the manual clutch cannot be driven at all.

On the other hand, in some cases, a semi-automatic system such as a semi-auto is installed in an existing vehicle. The semi-automatic system is simpler in structure and inexpensive compared to a full automatic system, but more complicated and expensive than a manual vehicle. Has a problem.

The present invention was devised to solve the above problems, and provides a clutch operating device for a vehicle that can be easily mounted on an existing vehicle to control the clutch relatively easily when operating the clutch pedal. Has its purpose. In particular, the present invention provides a convenience in use by operating the clutch using the clutch pedal, as well as operable by hand.

Another object of the present invention is to enable the operation of the clutch pedal as well as the electronic control operation to enable the disabled to easily operate the clutch.

Still another object of the present invention is to facilitate installation and removal by connecting the completed clutch operating device to an existing clutch device.

As shown in FIGS. 2 to 6, the clutch operating device 100 for a vehicle according to the present invention is to cut off power by cutting off the clutch 12 as described above. Pressure on / off valve 110 for supplying and blocking pressure supplied from a pressure source (not shown), and pressure on / off valve actuation button 120 for opening (pressure supply) of pressure on / off valve 110. , Pressure distribution valve 130 for distributing the pressure supplied from the pressure source, hydraulic cylinder 140 for blocking the clutch 12 via the internal piston 142, pressure distribution valve 130 The pressure introduced from the booster 150 having the booster piston 152 for operating the hydraulic cylinder 140 through the boosted pressure, the pressure between the piston 142 and the booster piston 152 of the hydraulic cylinder 140 is connected to the pressure Pressure supplied from the dispensing valve 130 The pressure control valve 160 for adjusting the pressure to make the connection of the clutch 12 to be discharged and the power supplied to the pressure on / off valve 110 when the clutch 12 is shut off turn off the pressure. And a pressure on / off valve power shut-off means for closing the off valve 110. This configuration is configured inside the case 102 constituting the exterior of the clutch operation device 100 for a vehicle.

The clutch clutch device 100 for automobiles of the present invention configured as described above is a power cutoff (clutch cutoff) operation in a state where a pressure supplied from a pressure source is supplied to a pressure on / off valve 110 (the power supply is turned on ( On), that is, the pressure on / off valve 110 is opened by pressing the pressure on / off valve operation button 120 so that the pressure supplied from the pressure source passes through the pressure distribution valve 130 via the booster ( By supplying to the 150, the power of the clutch device can be cut off through the boosted pressure of the booster 150, and the direction of discharging the flow of pressure in the pressure control valve 160 at the time of transmission of power (when the clutch is connected) By switching to the clutch 12 is made to be connected.

In more detail, when the gear is shifted while the vehicle is running or stopped, the pressure on / off valve operation button is installed at one side of the shift lever (gear shift lever) 104 and electrically connected to the pressure on / off valve 110. Depressing 120 opens the pressure on / off valve 110, whereby the pressure supplied from the pressure source to the tip of the pressure on / off valve 110 passes through the open pressure on / off valve 110. It is introduced into the pressure distribution valve 130.

On the other hand, the pressure introduced into the pressure distribution valve 130 is distributed through a plurality of distribution holes (134, 134a, 134b). The pressure distributed to the double booster 150 is boosted by the booster 150 to operate the hydraulic cylinder 140, and thus the hydraulic cylinder 140 operates the clutch booster 20 through the piston 142 to clutch the clutch. (12) is cut off (power off). In this way, the gear 12 can be shifted by blocking the clutch 12.

As described above, when the clutch 12 is blocked, the pressure supplied to the pressure distribution valve 130 is a pressure on / off valve 110, a pressure distribution valve 130, a booster 150, and a pressure control valve. It is stagnant (the state of no flow) between the 160 and the open valve 180 to be described later to maintain the blocked state of the clutch 12.

In addition, the pressure control valve 160 described above is connected between the piston 142 of the hydraulic cylinder 140 and the booster piston 152 of the booster 150 so that the booster piston 152 is boosted by the booster 150. When the clutch 12 is moved in the direction of blocking the pressure control valve 160 is also moved by the movement distance of the booster piston 152. At this time, when the pressure control valve 160 is moved by a set distance, the pressure on / off valve 110 is cut off from the pressure on / off valve intermittent switch 176, which will be described later, to turn on the pressure on / off valve 110. Allow to be blocked. That is, the pressure on / off valve 110 is blocked (closed) so that the pressure supplied from the pressure source is no longer supplied.

In the clutch operating device 100 for a vehicle according to the present invention, the pressure on / off valve 110 is prevented from being discharged from the pressure source to the open valve 180 which will be described later. An open valve blocking means is further provided to cut off (close) the open valve 180 by applying power to the open valve 180 before shutting off the power to shut off the pressure on / off valve 110. That is, the open valve 180 described later is closed before the power supply of the pressure on / off valve 110 is cut off and the supply of pressure from the pressure source is cut off.

As described above, the reason why the open valve 180 to be described below is closed before the supply of pressure from the pressure source is cut off by the power supply of the pressure on / off valve 110 is shut off when the open valve 180 is opened. This is the reason why the clutch 12 is difficult to shut off (power shut-off) because the supplied pressure is continuously discharged even if this is continuously supplied.

On the other hand, the reason why the clutch 12 is blocked by the pressure supplied from the pressure source even when the open valve 180 to be described later is opened is the pressure on / off valve when the clutch 12 is shut off (when power is shut off). The pressure supplied to the front end of the pressure on / off valve 110 is instantaneously opened when the 110 is opened, and the pressure distribution valve 130 is boosted in the diesel gas booster 150, and then the boosted pressure is increased by the hydraulic cylinder ( This is because it is transmitted to the clutch booster 20 via the 140.

On the other hand, the action for transmitting power after shifting the gear in the state in which the clutch 12 is made is a booster by discharging the pressure supplied into the pressure distribution valve 130 through the pressure regulating valve 160 When the booster piston 152 is restored by the restoring force of the restoring spring 154 installed in the interior of 150, and thus the pressure for blocking the clutch 12 is returned to its original position, the connection of the clutch 12 is made. The transmission of power is made.

In the configuration of the clutch operating device 100 for automobiles according to the present invention as described above, the pressure supplied from the pressure source may be air pressure or hydraulic pressure. At this time, when the pressure supplied from the pressure source is air pressure, the air pressure discharged from the pressure control valve 160 is discharged to the atmosphere. At this time, since the noise generated by the air pressure discharged into the atmosphere is further provided with a silencer 160a on the pressure discharge hole (161b). When the pressure supplied from the pressure source is hydraulic pressure, the hydraulic pressure discharged from the pressure control valve 160 is discharged to the hydraulic circulation system (not shown) to circulate. Usually, when using the pressure supplied by hydraulic pressure, the hydraulic pressure which makes smooth the steering wheel operation of a motor vehicle is used.

In the clutch operation apparatus 100 for a vehicle according to the present invention, the hydraulic cylinder 140 is connected to the clutch booster 20 of the clutch device 10 by the hydraulic transmission pipe 144, and also the master of the clutch device 10. It is connected to the cylinder (16). The hydraulic cylinder 140 configured as described above presses the clutch 12 by pressing the pressure generating oil flowing into the interior of the hydraulic cylinder 140 from the master cylinder 16 through the piston 142 when the clutch is blocked (power off). Will be blocked. Therefore, it can be seen that the present invention is configured such that the clutch (blocking power) of the clutch through the clutch pedal 14 can be made together with the blocking (blocking power) of the clutch through the clutch operating device 100.

More specifically, since the hydraulic cylinder 140 is connected to the clutch booster 20 of the clutch device 10 by the hydraulic transmission pipe 144, and also to the master cylinder 16 of the clutch device 10, the hydraulic pressure is reduced. It can be seen that the pressure generating oil in the master cylinder 16 of the clutch device 10 acts on the operation from the cylinder 140 to the clutch 12, so that the clutch is blocked by the clutch operating device 100 ( It can be seen that the clutch (blocking power) can be made through the clutch pedal 14 together with the power blocking.

That is, in the configuration of the clutch operating device 100 for a vehicle according to the present invention, the hydraulic transmission pipe 144 clutches the pressure generated by the stepping force of the clutch pedal 14 through the master cylinder 16 and the hydraulic cylinder 140. It is configured to be supplied to the booster 20 so that the clutch 12 can be interrupted by the clutch pedal 14.

Referring to the clutch operation device 100 for a vehicle according to the invention in more detail as follows. First, the case 102 constituting the outside to protect other components consists of a case body 102a having a space formed therein and a lid 102b covering the upper portion of the case 102. Of course, to protect them, the clutch operation device 100 for a vehicle of the present invention enables to be installed on one side of the bonnet of the vehicle.

The pressure on / off valve 110 supplies and shuts off the pressure supplied from the pressure source, and the pressure on / off valve 110 is opened and closed by on / off of the power supply to turn the pressure on / off. The pressure supplied to the front end of the valve 110 is supplied or blocked to the pressure distribution valve 130.

The pressure on / off valve 110 as described above is normally opened when the supply of power is on (opened) and the pressure supplied to the tip of the pressure on / off valve 110 is the pressure on / off valve 110. It is supplied to the pressure distribution valve 130 through, and when the power supply is off (off) it is closed (closed) to block the pressure supplied from the pressure source from passing through the pressure on / off valve 110. .

The pressure on / off valve actuation button 120 is for turning on / off the pressure on / off valve 110. The pressure on / off valve actuation button 120 is a pressure on / off valve ( It is electrically connected to 110 is installed on one side of the shift lever (gear shift lever) 104.

The pressure on / off valve operation button 120 configured as described above is applied to the pressure on / off valve 110 by applying power to the pressure on / off valve 110 through the operation of pressing the clutch when the clutch is shut off according to the gear shift. The on / off valve 110 is opened so that the pressure supplied to the tip of the pressure on / off valve 110 is supplied to the pressure distribution valve 130 through the pressure on / off valve 110.

The above-described pressure on / off valve operation button 120 is kept pressed or touched to shut off the clutch 12. That is, when the pressure is supplied to the pressure distribution valve 130 by the pressing operation of the pressure on / off valve operation button 120 and the clutch 12 is blocked, the pressure regulating valve 160 is moved. Accordingly, since the power applied to the pressure on / off valve 110 is cut off by the pressure on / off valve power shut-off means and the pressure on / off valve 110 is closed, the pressure on / off valve actuation button 120 Keep pressing or touching the clutch 12 is cut off.

On the other hand, the configuration for blocking the pressure on / off valve 110 so that the pressure supplied from the pressure source does not pass through the pressure on / off valve 110 will be described later.

The pressure distribution valve 130 is for distributing pressure to a plurality of places, and the pressure distribution valve 130 boosts the pressure supplied from the pressure source at the opening of the pressure on / off valve 110. The pressure control valve 160 and the open valve 180 to be described later will be distributed.

Therefore, as can be seen in the configuration as described above, the pressure distribution valve 130, the pressure inlet hole 132 through which the pressure supplied via the pressure on / off valve 110 flows in and the inlet pressure booster 150 It can be seen that the distribution holes 134, 134a, 134b for distributing to the pressure control valve 160 and the open valve 180 to be described later. The pressure on / off valve 110 and the pressure distribution valve 130, the pressure distribution valve 130 and the booster 150, the pressure distribution valve 130 and the pressure control valve 160, the distribution valve ( 130 and the open valve 180 to be described later are connected by a connecting tube 106.

Meanwhile, the pressure supplied to the pressure distribution valve 130 configured as described above flows into the pressure distribution valve 130 via the pressure on / off valve 110, and then each of the distribution holes 134 134a. It can be seen that through the 134b, it is instantaneously distributed to the booster 150, the pressure control valve 160 and the open valve 180 to be described later.

The hydraulic cylinder 140 transmits the pressure boosted by the booster 150 to the clutch booster 20, and the hydraulic cylinder 140 is supplied to the booster 150 via the pressure distribution valve 130. When the pressure is increased, the booster is operated according to the movement of the piston 152 to pressurize the oil for generating oil in the hydraulic cylinder 140 through the piston 142, and thus the clutch booster 20 of the clutch device 10. ) To transmit pressure.

On the other hand, the hydraulic cylinder 140 as described above is connected to the clutch booster 20 of the clutch device 10 by the hydraulic transmission pipe 144, and also to the master cylinder 16 of the clutch device 10. . Therefore, it can be seen that the clutch 12 is blocked by the clutch operating device 100 and the clutch 12 by the pedaling force of the clutch pedal 140 according to the present invention via the hydraulic cylinder 140. .

Booster 150 is for boosting the pressure supplied from the pressure distribution valve 130, the booster 150 is always applied in the direction to the original position by the elastic force of the restoring spring (154) And a booster piston 152 connected to the piston 142 of the hydraulic cylinder 140.

The booster 150 configured as described above boosts the pressure supplied from the pressure distribution valve 130 when the clutch 12 is blocked (when the power is blocked), thereby boosting the booster piston 152 of the clutch 12. It will move in the blocking direction. Accordingly, the piston 142 of the hydraulic cylinder 140 connected to the booster piston 152 also proceeds in the blocking direction of the clutch 12.

On the other hand, when the clutch 12 is connected (at the time of transmission of power), the boosted force for advancing the booster piston 152 in the blocking direction of the clutch 12 disappears, so that the booster piston is restored by the restoring force of the restoring spring 154. 152 is restored to its original position. Therefore, since the force which cut off the clutch 12 disappears, the clutch 12 is connected and power is transmitted. That is, it will be in the state which can drive.

The pressure regulating valve 160 is for connecting the clutch 12 by discharging the supplied pressure as shown in FIG. 6, and the pressure regulating valve 160 has two parts, a booster 150 and an inlet cylinder 140. The piston 152 and 142 are connected between the booster piston 152 and the piston 142 of the hydraulic cylinder 140 to be moved at the same time by the distance moved in the forward and backward direction.

The pressure regulating valve 160 installed as described above has a pressure on / off valve 110, a pressure distribution valve 130, and pressure distribution maintaining the shut-off state of the clutch 12 according to the shut-off of the clutch 12. The valve 130 and the booster 150, the pressure distribution valve 130 and pressure control valve 160, the discharge pressure between the distribution valve 130 and the open valve 180 to be described later to discharge the clutch ( 12) is made.

On the other hand, the configuration of the pressure control valve 160 as described above is a pressure inlet hole 161a through which the pressure supplied via the pressure distribution valve 130 is introduced and a pressure discharge hole 161b for discharging the pressure therein. While the upper and lower pressure chambers (161c, 161d) are formed in communication with each other, and the upper pressure chamber (161c) has an insertion hole (161e) formed outside the upper portion of the lower pressure chamber (161d) Opening holes 161f are formed on the outside, and the lower cap 162 and upper and lower pressure chambers 161c and 161d that are screwed into the valve body 161 and the opening holes 161f of the valve body 161 are formed. It is installed in the lower pressure chamber 161d so that the outer peripheral surface of the upper side is in close contact with the sealing ring 163 supported at each of the upper ends of the sealing ring 163 and the sealing ring 163 on the lower pressure chamber 161d side, and the pressure is applied to the upper pressure chamber 161c. The valve body 164 and the valve body 164 to supply and shut off the gas, and constantly contact the sealing ring 163 on the lower pressure chamber 161d side. The valve body pressing rod 166 and the valve body pressing rod 166 are inserted through the elastic spring 165, the upper side insertion hole 161e to press the valve body 164 in the direction of It consists of a pressure control lever 167 to pressurize.

In the above-described configuration of the pressure control valve 160, the pressure control lever 167 is rotated in accordance with the stepping amount of the accelerator pedal, so if the user slowly presses the accelerator pedal, the pressure control lever 167 rotates gradually, and thus the valve body 164 is gradually lowered so that the upper pressure chamber 161c is gradually opened, and the pressure is gradually released. Therefore, the pressure control valve 160 can adjust the connection speed of the clutch 12 by adjusting the discharge of the pressure in accordance with the degree of rotation of the pressure control lever 167. In other words, it is possible to adjust the transmission speed of the power. Therefore, such a pressure regulating valve 160 may be referred to as a proportional control valve because it adjusts the opening degree between the upper and lower pressure chambers 161c and 161d to control the discharge of pressure.

The pressure discharge action of the pressure control valve 160 configured as described above, first, when the clutch pedal connection (power transmission) when the pedal force of the accelerator pedal (not shown) occurs, the pressure control lever 167 rotates to a certain range The upper end of the valve body pressing rod 166 is pushed downward, whereby the valve body 164 is separated from the lower sealing ring 163 so that the upper and lower pressure chambers 161c and 161d communicate with each other. When the upper and lower pressure chambers 161c and 161d communicate with each other, the pressure on / off valve 110 and the pressure distribution valve 130, the pressure distribution valve 130 and the booster 150, and the pressure distribution valve ( The stagnant pressure between the pressure control valve 160, the distribution valve 130, and the open valve 180 to be described later is discharged to the pressure discharge hole 161b via the upper pressure chamber 161c.

Therefore, since the force to pressurize the booster piston 152 is eliminated, the booster piston 152 is returned to its original position by the elastic force of the restoring spring 154, whereby the clutch 12 is connected to transmit power.

In the configuration of the pressure regulating valve 160 as described above, the upper and lower pressure chambers 161c and 161d of the valve body 161 are for injecting pressure and discharging pressure, and the upper and lower pressure chambers ( 161c and 161d are formed in the form of mortar, and the intermediate part is formed in a narrow form to communicate with each other. At this time, a pressure inlet hole 161a through which the pressure distributed from the pressure distribution valve 130 flows in is formed at one side of the lower pressure chamber 161d, and a lower pressure chamber 161d at one side of the upper pressure chamber 161c. A pressure discharge hole 161b for discharging the internal pressure is formed.

An insertion hole 161e is formed in the upper side of the upper pressure chamber 161c, and a valve body pressing rod 166 is inserted, and an opening hole 161f is formed in the lower side of the lower pressure chamber 161d, which will be described later. The valve body 164 and the elastic spring 165 are installed through the opening hole 161f. Thus, after installing the valve body 164 and the elastic spring 165 through the opening hole 161f, the lower cap 162 is fastened and the valve body 164 is lower pressure chamber 161d by the elastic spring 165. ) To be elastically supported.

The sealing ring 163 seals between the valve body pressing rod 166 and the insertion hole 161e installed inside the upper pressure chamber 161c through the insertion hole 161e, and also seals the upper and lower pressure chambers 161c, The intermediate portion of 161d and the valve body 164 are sealed to prevent the pressure in the lower pressure chamber 161d from leaking into the upper pressure chamber 161c. The sealing ring 163 is installed at the upper end of the upper pressure chamber 161c and the upper part of the lower pressure chamber 161d.

The valve body 164 opens and closes between the upper pressure chamber 161c and the lower pressure chamber 161d to shut off the clutch (pressure transmission) when the pressure flowed into the lower pressure chamber 161d through the pressure inlet hole 161e. By supplying and blocking to the upper pressure chamber 161c, the valve body 164 is provided inside the lower pressure chamber 161d so that the outer peripheral surface of the upper side is in close contact with the sealing ring 163 on the lower pressure chamber 161d side. . In this case, a seat groove 164a is formed in the upper center of the valve body 164 formed in a conical shape in which the valve body pressing rod 166 inserted into the upper pressure chamber 161c is inserted through the insertion hole 161e.

The elastic spring 165 supports the valve body 164 in the lower pressure chamber 161d so that the elastic force acts in a direction in which the elastic spring 165 is in constant contact with the sealing ring 163 on the lower pressure chamber 161d. Until the force greater than the elastic force of) is applied, the conical outer circumferential surface of the valve body 164 is brought into close contact with the sealing ring 163 on the lower pressure chamber 161d side.

The valve body pressing rod 166 is for communicating the upper and lower pressure chambers 161c and 161d by pressing the valve body 164. The valve body pressing rod 166 is hydraulically applied at the time of power transmission (clutch connection). It is pressed by the act of pressing the control lever 167, and presses the valve body 164 so that upper and lower pressure chambers 161c and 161d may mutually communicate. The valve body pressing rod 166 is inserted through the insertion hole 161e, and one end is coupled to the seat groove 164a of the valve body 164, while the other end is installed to protrude out of the upper portion of the valve body 161. do.

The pressure control lever 167 is rotated to a certain range so that the lower side of the upper pressure chamber 161c can be opened by pressing the valve body pressing rod 166. The pressure control lever 167 is a valve body 161. It is installed to be rotated to a certain range on the upper one side. The pressure control lever 167 installed as described above is rotated by an external force at the time of power transmission (when the clutch is connected) to press the valve body pressing rod 166 to open the lower side of the upper pressure chamber 161c, thereby to lower the pressure chamber 161d. The pressure flow is discharged to the pressure discharge hole 161b through the upper pressure chamber 161c.

On the other hand, the external force for rotating the pressure control lever 167, one end is connected to the end of the pressure control lever 167, the other end is connected to the throttle valve (not shown) side when the pedal force of the accelerator pedal (not shown) occurs It is a lever cable 168 that pulls and rotates the pressure control lever 167 in the pedaling direction of the accelerator pedal.

As can be seen from the configuration of the pressure control valve 160 as described above, the clutch device 100 for automobiles according to the present invention has the effect of supplying the pressure supplied only by stepping on the accelerator pedal when the power is transmitted (when the clutch is connected). It discharges and connects the clutch 12, and a power is transmitted.

That is, when the pressure adjusting lever 167 is rotated by the pedal force of the accelerator pedal and the upper and lower pressure chambers 161c and 161d communicate with each other, the pressure on / off valve 110 and the pressure distribution valve 130, The static pressure between the pressure distribution valve 130 and the booster 150, the pressure distribution valve 130 and the pressure control valve 160, the distribution valve 130, and the open valve 180 to be described later is an upper pressure. It discharges through the pressure discharge hole 161b via the seal 161c.

On the other hand, since the pressure control lever 167 described above is rotated only by the pedaling force of the accelerator pedal, it is possible to finely adjust the power transmission. That is, when the accelerator pedal is gradually pressed, power is gradually transmitted.

The pressure on / off valve power cut-off means is to cut off the supply of pressure by cutting off the power of the pressure on / off valve 110 after the clutch 12 is cut off (power cut off). The power cut-off means turns off the power supplied to the pressure on / off valve 110 when the movement of the pressure regulating valve 160 is increased by a set distance during the boosting of the booster 150. ) Is closed.

Therefore, even if the pressure on / off valve operation button 120 provided on the shift lever 104 to open (pressure supply) the pressure on / off valve 110 by the pressing operation is kept pressed, the clutch 12 After the shutoff (power off) is made, the pressure on / off valve 110 is shut off by the pressure on / off valve power shutoff means.

The above-described pressure on / off valve power cut-off means is configured to be movable to the left and right on one side of the pressure control valve 160, the pressure on / off valve intermittent rod 170, the thread 170a is formed at the rear end, The length adjusting screw 172 is fastened to the thread 170a of the pressure on / off valve intermittent rod 170 and adjusts the length of the tip end of the pressure on / off valve intermittent rod 170, and the pressure on / off valve intermittent rod 170 Pressure on / off when the end of the pressure intermittent rod 170 interlocks when the elastic spring 174 and the clutch 12 which are acting in the direction of advancing the distal end of the cuff and the clutch 12 are blocked. It is composed of a pressure on / off valve intermittent switch 176 to cut off the power flowing to the valve 110 to cut off the pressure supplied to the pressure distribution valve 130 through the pressure on / off valve 110.

The pressure on / off valve power shut-off means configured as described above may control the pressure on / off valve when the pressure regulating valve 160 is also moved in the power shut-off direction by the movement of the booster piston 152 at the time of clutch shut-off (power shut-off). As the pressure on / off valve intermittent rod 170 holding the switch 176 falls, the pressure on / off valve 110 is shut off by turning off the power flowing in the pressure on / off valve 110.

On the other hand, when the pressure regulating valve 160 is also restored to its original position by the elastic force of the restoring spring 154 restoring the booster piston 152 to its original position when the power is transmitted, the pressure on / off valve intermittent switch 176 is pressurized. It is pressed by the on / off valve intermittent rod 170.

On the other hand, the pressure on / off valve intermittent switch 176 in the pressure on / off valve power shut-off means configured as described above is the pressure on / off when the power is cut off and the power is applied to the pressure on / off valve 110 Only the function of turning off the power of the off valve 110 (off), but does not turn on the power of the pressure on / off valve (110).

The configuration of the pressure on / off valve power cut-off means as described above is to stop the supply of pressure after the power is cut off so that no more pressure is supplied.

The pressure on / off valve intermittent rod 170 described above is depressed from the pressure on / off valve intermittent switch 176 when the power is cut off while the pressure on / off valve intermittent switch 176 is pressed. The pressure on / off valve intermittent rod 170 is installed in parallel with the booster piston 152 on the upper side of the pressure regulating valve 160 as shown in FIGS. . At this time, the thread 170a is formed at the rear end of the pressure on / off valve intermittent rod 170.

The length adjusting screw 172 is for adjusting the length of the distal end of the pressure on / off valve intermittent rod 170, and the length adjusting screw 172 is provided on the thread 170a of the pressure on / off valve intermittent rod 170. The length of the distal end of the pressure on / off valve intermittent rod 170 is adjusted by being fastened or tightened.

The elastic spring 174 acts to force the front end of the pressure on / off valve intermittent rod 170 to the pressure on / off valve intermittent switch 176, and the elastic spring 174 has its elastic force. Through the tip of the pressure on / off valve intermittent rod 170 to act in the pressure on / off valve intermittent switch 176 direction.

The above-mentioned elastic spring 174 is a pressure on / off valve intermittent rod 170 until the set end length of the pressure on / off valve intermittent rod 170 is exposed, even if the pressure regulating valve 160 moves in the power shut-off direction. To keep pressing the pressure on / off valve intermittent switch 176 through the elastic force.

The pressure on / off valve intermittent switch 176 supplies power to the pressure on / off valve 110 when the front end of the pressure on / off valve intermittent rod 170 drops when the clutch 12 is shut off (power off). When the pressure on / off valve intermittent switch 176 is pressed by the pressure on / off valve intermittent rod 170 and the front end of the pressure on / off valve intermittent rod 170 drops during power off, the pressure is turned on. The power flowing to the on / off valve 110 is cut off.

The above-described pressure on / off valve intermittent rod 170 adjusts the length of the tip of the pressure on / off valve intermittent rod 170 through the length adjusting screw 172 according to the degree of wear of the clutch disc (not shown). The falling speed with the on / off valve intermittent switch 176 can be adjusted. That is, when the length of the tip end of the pressure on / off valve intermittent rod 170 is increased, the speed at which the pressure on / off valve intermittent rod 170 is shortened compared to the case where the length of the pressure on / off valve intermittent rod 170 is shortened. You can slow down.

On the other hand, the clutch operation device 100 for a vehicle according to the present invention is further provided with a downhill power transmission means for transmitting the power of the clutch 12 without pressing the accelerator pedal on the downhill, such a downhill power transmission means. Is connected to the pressure distribution valve 130 is made of a structure for discharging the pressure supplied from the pressure source at any time, but when the power is applied to one side of the open valve 180 and the shift lever 104 to block the discharge of pressure. It is composed of an open valve operation button 182 to be installed but open the open valve 180 is blocked by the pressing action to discharge the pressure supplied from the pressure source. The description of the downhill power transmission means of this configuration will be described after the description of the open valve blocking means to be described later.

In addition to the configuration of the downhill power transmission means described above, the vehicle clutch operating device 100 of the present invention has an open valve (before closing) when the power on / off valve 110 is shut off (closed) when the power is shut off. It is further provided with an open valve blocking means for blocking the 180 to block the pressure supplied from the pressure source to the pressure distribution valve 130 is not discharged through the open valve 180, this open valve blocking means is An open valve intermittent rod 190 is formed to be screwed to the thread 190a of the open valve intermittent rod 190 and the open valve intermittent rod 190, which is formed to be movable to the left and right on the other side of the pressure regulating valve 160. When the length adjustment screw 192 for adjusting the length of the front end of the rod 190, the elastic spring 194 and the clutch 12 in which the force acts in the direction of advancing the front end of the open valve intermittent rod 190 ( Open valve stage) The distal end of the rod 190 is made fall by the open valve intermittent switch 196 to block the pressure discharged by applying a power to the open valve 180. The

The open valve blocking means configured as described above is pressing the open valve intermittent switch 196 when the pressure regulating valve 160 is also moved in the power blocking direction by the movement of the booster piston 152 when the clutch is blocked (power is blocked). The open valve intermittent rod 190 is dropped to be turned on to block the open valve 180. That is, the open valve 180 is closed to block the pressure discharged through the open valve 180 via the pressure distribution valve 130. At this time, when the pressure is hydraulic (油壓) the hydraulic pressure (시) discharged when the open valve 180 is opened is discharged to the hydraulic circulation system.

On the other hand, when the pressure regulating valve 160 is also restored to its original position by the elastic force of the restoring spring 154 restoring the booster piston 152 to its original position when the power is transmitted, the open valve interrupt switch 196 may open the valve intermittent rod. It is pressed by 190.

On the other hand, the shutoff of the open valve 180 by the open valve intermittent switch 196 at the time of power interruption (clutch shutoff) is more than the shutoff of the pressure on / off valve 110 by the pressure on / off valve intermittent switch 176. The state of the power interruption (closure of the clutch) is maintained by the previously supplied pressure.

That is, the power on / off valve 110 is cut off by the power on / off valve power cut-off means when the power is cut (clutch cut off), and the pressure on / off valve 110 is cut off to supply pressure. Even though the open valve 180 remains open, the clutch 12 is not blocked because the pressure supplied to the pressure distribution valve 130 is discharged through the open valve 180. Therefore, the open valve 180 must be blocked before the on / off valve 110 is blocked by the on / off valve power shut-off means.

The open valve intermittent rod 190 described above depresses the open valve intermittent switch 196 when the power is transmitted and falls from the open valve intermittent switch 196 when the power is interrupted. 3 and 4 is installed in parallel with the booster piston 152 on the lower side of the pressure regulating valve 160, but is installed to be able to move left and right. At this time, the thread 190a is formed at the rear end of the open valve control rod 190.

Length adjusting screw 192 is to adjust the length of the tip end of the open valve intermittent rod 190, the length adjusting screw 192 is fastened or loosened by being fastened to the thread (190a) of the open valve intermittent rod 190. Through the end of the pressure open valve intermittent rod 190 to adjust the length.

The elastic spring 194 is a force acting in the direction to close the front end of the open valve control rod 190 to the open valve control switch 196, the elastic spring 194 is an open valve control rod through the elastic force. The tip end portion of 190 is acted in the direction of the open valve interrupt switch 196.

The aforementioned elastic spring 194 opens the open valve intermittent rod 190 through an elastic force until the set tip length of the open valve intermittent rod 190 is fully exposed, even if the pressure regulating valve 160 moves in the power shutoff direction. The intermittent switch 196 can be kept pressed.

The open valve control switch 196 is to cut off the flow of the power to the open valve 180 when the front end of the open valve control rod 190 falls when the clutch 12 is blocked (power off). The switch 196 is pressed by the open valve intermittent rod 190, and when the power is cut off, when the tip of the open valve intermittent rod 190 falls, the switch 196 is applied to the open valve 180 to shut off (close) the power.

The open valve intermittent rod 190 described above may also adjust the length of the tip of the open valve intermittent rod 190 through the length adjusting screw 192 to adjust the falling speed with the open valve intermittent switch 196. In other words, when the length of the tip of the open valve control rod 190 is increased, the falling speed with the open valve control switch 196 can be slowed down compared with the case where the length of the open valve control rod 190 is shortened.

When the downhill power transmission means that the power of the clutch 12 is transmitted without depressing the accelerator pedal on the downhill as described above, the descending speed of the vehicle may be accelerated when the downhill power transmission means accelerates through the accelerator pedal when descending from a high region such as a hill. In order to prevent the vehicle from rolling due to the gear shift, the downhill power transmission means has an open valve operation button 182 provided under the pressure on / off valve operation button 120 of the shift lever 104. Pressure on / off valve 110 and pressure distribution valve 130 to maintain the clutch shut-off (power shut-off) state by opening the closed open valve 180 when the clutch shuts off (power shut-off) by pressing). Pressure distribution valve 130 and booster 150, pressure distribution valve 130 and pressure control valve 160, the static pressure between the distribution valve 130 and the open valve 180 is discharged It was made such that the connection of the clutch 12, power is delivered.

In the configuration of the downhill power transmission means described above, the open valve 180 is connected to the pressure distribution valve 130 and is always opened until it is blocked by the open valve shutoff means when the power is shut off. The open valve 180 is a pressure on / off valve 110 and the pressure distribution valve 130, the pressure distribution valve 130 and the booster 150 in order to maintain the shut-off state of the clutch 12 when the power is cut off ), Since the pressure supplied between the pressure distribution valve 130 and the pressure control valve 160, the distribution valve 130 and the open valve 180 must be stagnant, the open valve ( Closing 180 is essential.

According to the closing of the open valve 180 as described above, the pressure on / off valve 110 and the pressure distribution valve 130, the pressure distribution valve 130 and the booster 150, the pressure distribution valve 130 And the pressure control valve 160, the distribution valve 130, and the pressure supplied between the open valve 180 are stagnant and open on the shift lever 104 in the state of maintaining the shut-off state of the clutch 12 when shut off. When the valve operation button 182 is pressed, the open valve 180 which is closed by the open valve shutoff means is opened to open the pressure on / off valve 110, the pressure distribution valve 130, the pressure distribution valve 130, and the booster. (150), the pressure distribution valve 130 and the pressure regulating valve 160, the discharge of the static pressure between the distribution valve 130 and the open valve 180 is discharged (connection of the clutch 12) is Make it happen.

The following describes the operation of the clutch operation device 100 for a vehicle according to the present invention.

7 is a side view showing a state in which a clutch cutoff (power cutoff) of the clutch operation device for automobiles according to the present invention is made.

As shown in FIG. 7, the clutch operating apparatus 100 for a vehicle according to the present invention firstly opens the pressure on / off valve 110 through a pressing action of the pressure on / off valve operating button 120 (see FIG. 2). Open it. Accordingly, the pressure supplied from the pressure source to the front end of the pressure on / off valve 110 passes through the pressure on / off valve 110 at the moment the pressure on / off valve 110 is opened. The pressure introduced into the pressure distribution valve 130 is introduced into the booster 150, the pressure regulating valve 160, and the opening through the respective distribution holes 134, 134a, and 134b of the pressure distribution valve 130. It is supplied to the valve 180.

As described above, the pressure supplied to the booster 150 among the pressures supplied through the respective distribution holes 134, 134a and 134b of the pressure distribution valve 130 is boosted by the booster 150. Accordingly, the booster piston 152 is moved in the direction of interruption of power. At this time, the pressure control valve 160 is also moved according to the movement of the booster piston 152, so that the open valve intermittent rod 190 of the open valve shutoff means is separated from the open valve intermittent switch 196 of the open valve 180. The closing is made, and then the pressure on / off valve intermittent rod 170 of the pressure on / off valve power shut-off means is separated from the pressure on / off valve intermittent switch 176 to close the pressure on / off valve 110. .

As described above, after the closing (blocking) of the open valve 180 and the pressure on / off valve 110 is performed, the supplied pressure is supplied to the pressure on / off valve 110 and the pressure distribution valve 130 and the pressure distribution. The valve 130 and the booster 150, the pressure distribution valve 130 and the pressure regulating valve 160, stagnated between the distribution valve 130 and the open valve 180 to block the state of the clutch 12 Will be maintained. 7 is a state in which power is cut off.

Figure 8 is a side view showing the action of the pressure control lever when the clutch connection (power transmission) in the clutch made (power off) of the clutch operation device for automobiles according to the present invention, Figure 9 is a pressure control valve according to FIG. 10 is a side view showing a state in which a clutch connection (power transmission) of the clutch operation device for a vehicle according to the present invention is made.

8 to 10 show the operation of the clutch operating device 100 for a vehicle according to the present invention in the transmission of power. First, when the accelerator pedal is pressed in a state in which power is cut off as shown in FIG. 7, the pressure control lever 167 rotates in one direction as shown in FIG. 8, and thus the valve body as shown in FIG. 9. The push bar 166 is pressed by the pressure control lever 167 to move downward to press the valve body 164 downward. As such, when the valve body 164 is pressed downward, the valve body 164 is spaced apart from the sealing ring 163 supported on the upper side of the lower pressure chamber 161d so that the upper and lower pressure chambers 161c and 161d communicate with each other. Accordingly, the pressure on / off valve 110 and the pressure distribution valve 130, the pressure distribution valve 130 and the booster 150, the pressure distribution valve 130 and the pressure control valve 160, distribution The stagnant pressure between the valve 130 and the open valve 180 is discharged to the pressure discharge hole 161b through the lower pressure chamber 161d (and the upper pressure chamber 161c) of the pressure regulating valve 160. If the pressure is hydraulic pressure, it is circulated through the hydraulic circulation system, and if the pressure air pressure is discharged to the outside air.

Meanwhile, as described above, the pressure on / off valve 110 and the pressure distribution valve 130, the pressure distribution valve 130 and the booster 150, the pressure distribution valve 130 and the pressure control valve 160 are described. When the pressure stagnated between the distribution valve 130 and the open valve 180 is discharged through the pressure discharge hole 161b of the pressure control valve 160, a force for pressurizing the booster piston 152 as shown in FIG. 10. Since the disappearance of the booster piston 152 is restored by the restoring force of the restoring spring 154, accordingly the pressure control valve 160 is also restored.

As described above, when the pressure regulating valve 160 is also restored according to the restoration of the booster piston 152, the pressure on / off valve intermittent rod 170 of the pressure on / off valve shutoff means and the open valve intermittent rod of the open valve shutoff means. Each of the 190 presses the pressure on / off valve control switch 176 and the open valve control switch 196. On the other hand, in the clutch device 10, the clutch 12 is connected and power is transmitted.

In addition, when the clutch 12 is blocked in the state where power is being transmitted as described above, the clutch 12 may be blocked by the operation as described in FIG. 7.

The following shows another embodiment of the present invention.

11 is a block diagram showing another embodiment of the clutch operation device for a vehicle according to the present invention.

As shown in FIG. 11, another embodiment of the automobile clutch actuator 200 according to the present invention has a similar structure as in the example of the automobile clutch actuator 100 shown in FIGS. 2 to 10. However, there is no configuration of the hydraulic cylinder 140 (see FIGS. 2 to 10) as shown in FIGS. 2 to 10, and the end of the booster piston 252 is directly connected to the shift lever 24 of the clutch device. Only by the action of the booster piston 252 which is moved in the direction of blocking the clutch 12 when the booster 250 is boosted by the operation of the shift lever 24 is the only point that can be intermittent clutch 12.
