The present invention relates to a semi-auto clutch device for use in a vehicle, and more particularly, to a semi-auto clutch drive device for properly connecting a clutch disk to a fly wheel according to an engine output value (RPM, etc.) that varies depending on driving conditions of the vehicle. And a driving method.

In general, a manual clutch device operates a master cylinder by operation of a clutch pedal, a release cylinder by a master cylinder, and a clutch disk by a pressure plate according to the operation of the release cylinder. The disk is disconnected and connected to the fly wheel to control the torque transmitted from the engine to the transmission.

By the way, the manual clutch has a problem that a lot of fatigue occurs in the leg when driving in the city or traffic jam because the driver must pressurize the clutch pedal every time to shift the gear.

In order to solve this inconvenience, the automatic transmission with automatic shifting has the advantages of convenient driving and excellent riding comfort, but it is expensive at the time of initial purchase and consumes 20 to 30 percent of fuel consumption compared to manual transmission while driving. There are many disadvantages.

On the other hand, the semi-auto clutch device is to take advantage of both the manual transmission and the automatic transmission, and the power transmission of the vehicle by the operation of the brake pedal or the on / off operation of the clutch switch provided on the gear shift stick without operating the clutch pedal. By simply disconnecting / connecting, the gear shifting can be made freely. Conventional clutch devices having such a semi-auto function are equipped with a driving master cylinder for acting as a master cylinder between the master cylinder and the release cylinder of the vehicle, and then calculate the movement of the vehicle based on various sensor values mounted around the engine. When the clutch disk connection condition was reached, the drive master cylinder was driven to continuously attach the clutch disk.

However, in the conventional semi-auto clutch as described above, the engine output state is calculated based on various sensor values. Therefore, the calculated data is calculated when the vehicle is positioned on a slope, when placed on a flat surface, when a heavy load is loaded or not. There are many errors with the actual output from the engine, and when the connection time is early due to the connection time of the clutch disc determined by the data including the error, engine shaking or start-up will occur. If it is late, there is a problem that the start of the vehicle is slow or fuel consumption is increased.

In addition, when the connection of the clutch disk is in progress, the clutch disk is unconditionally connected due to unconditional connection, and there is a problem that the engine rattles and the engine is turned off.

Therefore, in order to solve the above problems, the present invention is to accurately determine the connection point of the clutch disk according to the output value of the engine that depends on the driving conditions of the vehicle, and to apply the anti-clutch state that frequently appears when a human is driving. Semi-engine that can smoothly transmit the power of the vehicle by using the engine rotation speed (rpm) as the reference data for determining the connection point and moving the clutch disc only as much as the value corresponding to the rising engine speed. It is an object of the present invention to provide an auto clutch driving device and a driving method.

Each cylinder (M4, M8, M9) is composed of push rods (M2, M6, M11) and pistons (M3, M7, M10), the driving master cylinder (M8) of the master cylinder (M4) in the 'manual mode' In addition to transmitting the operation to the release cylinder (M9) in the 'automatic mode' in accordance with the rotation of the motor 12 serves as the master cylinder (M4).

In addition, the master cylinder M4 generates hydraulic pressure from the operation of the clutch pedal M1, and the release cylinder M9 converts hydraulic energy of the master cylinder M4 or the driving master cylinder M8 into mechanical energy to convert the clutch disk. And a rod rod gear (M5) to change the rotational force of the motor 12 to a linear reciprocating motion to push the push rod (M6) in the drive master cylinder (M8) to generate hydraulic pressure.

2 is a block diagram of a semi-auto clutch driving device according to the present invention. The semi-auto clutch driving device according to the present invention includes an operation switch unit A, a sensing sensor unit B, a setting unit C, and a controller. 30, the motor 12, the engine speed increasing means 13, and the indicator light 14, the reference value of the various setting values according to the operation of the operation switch unit A is applied to the detected value of the sensor unit B. Accordingly, the motor 12 is rotated forward or reversely, the engine speed increasing means 13 is controlled, and the operation state is displayed on the indicator light 14. The operation switch unit A includes a forward button 1 for blocking the clutch disk, a half clutch button 2 for maintaining the half clutch state, a reverse button 3 for connecting the clutch disk, and a low speed mode button. (4), the detection sensor unit (B) is composed of an engine speed detection sensor (5), a brake detection sensor (6), a push rod position detection sensor (7), the setting unit (C) is a motor It consists of the speed adjusting volume 8, the push rod section setting volume 9, the anti-clutch setting volume 10, and the connection RMP (rpm) setting volume 11.

Referring to FIG. 2, the forward button 1 is for forward rotation of the push rod M6 by rotating the motor 12 forward to block the clutch disk, and the half clutch button 2 is half clutch state of the clutch disk. The reverse button 3 is for reverse rotation of the motor 12 to forcibly connect the clutch disk. The low speed mode button 4 is for removing and attaching the clutch disk as the rotation speed increases and decreases.

The engine speed detection sensor 5 detects the engine speed (rpm), the brake detection sensor 6 detects the operating state of the brake, and the push rod position detection sensor 7 rotates the motor 12. The rotation speed of the motor 12 is detected in order to detect the position of the push rod M6 transferred by the push rod transfer gear M5 that converts the movement into a linear movement.

The motor speed adjustment volume 8 is for adjusting the rotational speed of the motor 12, the push rod section setting volume 9 is for setting the moving section of the push rod M6, the anti-clutch setting volume 10 Is for the user to set the half clutch position. The connection ALMP setting volume 11 is for setting the reference engine speed RPM for starting the connection.

The motor 12 rotates forward or reverse under the control of the controller 30 to linearly reciprocate the push rod M6 through the push rod transfer gear M5. When the push rod M6 is advanced, the clutch disc is moved forward. The clutch disk is connected to the fly wheel when the wheel is dropped from the fly wheel and the push rod M6 is reversed. The engine speed increasing means 13 is for increasing the engine speed as a means of opening the throttle valve of the engine, and the indicator 14 is for displaying the operation state of the controller 30.

The controller 30 performs a predetermined control procedure as described below to reference the set value according to the operation of the operation switch unit A to rotate the motor 12 forward or reverse according to the detected value, and the engine speed It controls the ascending means 13 and controls the whole operation to display the operation state on the indicator 14. In addition, when the brake operation is detected from the brake sensor 6 in the low speed mode, the clutch disk is disconnected.

Next, a control operation of the semi auto clutch according to the present invention will be described with reference to FIG. 3.

3 is a control flowchart of the semi-auto clutch according to the present invention, wherein the control procedure of the present invention is performed by forward rotation of the motor 12 by the forward button 1 input signal or the signal of the brake detection sensor 6 to rotate the clutch disk. The clutch disk blocking step S1 to S9 for blocking and the engine speed increasing means 13 are controlled from the input signal of the half clutch button 2, and the motor 12 is driven to position the clutch disk in the half clutch state. And half clutch steps S10 to S18, and clutch disc connecting steps S19 to S25 for connecting the clutch disc from an input signal of the engine speed increase or the reverse button 3, respectively.

1. When the forward button is pressed or brake operation is detected in low speed mode

During operation, when the user presses the forward button 1 mounted on one side of the transmission gear stick to shift the gear or brake operation is detected from the brake detection sensor 6, the controller 30 stops the motor 12. It rotates and blocks the clutch disc by positioning the push rod M6 to the front position by which the clutch disc is blocked by the push rod feed gear M5.

In this way, while the clutch disc is blocked, the driver moves the transmission gearbox to engage the gear.

After the gear input, the controller 30 detects the engine speed rpm from the engine speed detection sensor 5 and compares it with the reference rpm value which is a reference of the connection point of the clutch disk. As a result of the comparison, when the engine speed (rpm) is higher than the reference rpm, the engine rotation is determined by determining the detected value of the push rod position sensor 7 (representing the push rod travel distance value as the rotation speed data of the motor). The motor 12 is reversed by only a few increments to reverse the push rod M6 by the push rod feed gear M5, and thus the clutch disc is connected. If there is no increase in the engine speed, the motor 12 is stopped and the connection degree of the clutch disc is made according to the engine speed increase value, thereby gradually transmitting the engine rotational force to the transmission.

In the above process, when the engine speed RPM is higher than the engine speed set by the driver with the connection ALPM setting volume 11 (that is, the connection ALMP), the push rod M6 is reversed to connect the clutch disk. The clutch disc is connected only as much as the engine speed increase, and if there is no increase, the clutch disc stops the connection progress and maintains the anti-clutch state according to the engine speed.

Therefore, in any situation at the start of every transport machine (e.g. loading of cargo or road inclination, etc.), an engine speed (RPM) detection sensor 5 enables the engine to indicate the load state of the drive shaft most sensitively and precisely. The optimum speed can be controlled by using the RPM signal. That is, the moving distance of the push rod M6 is adjusted according to the engine speed (RPM) (that is, the engine moves only as much as the speed increase value), and the engine speed increase speed is equal to the push rod feed speed. When the clutch switch provided on the stick is started on, the gearshift gear is shifted to a gear suitable for starting, and the accelerator pedal M1 is properly operated, the push rod M6 also increases the engine speed at the same time as the engine speed RPM is increased. When the disk starts to be connected as much as the ascending value and the speed, the engine starts to load from the moment.The weaker the disk connection speed is, the faster the speed becomes. The disk connection speed is gradually slowed down, and the engine speed is gradually increased when the power is almost transmitted, and eventually the connection is made quickly through the half-clutch state. The.

Sometimes, when there is no change in the number of revolutions, the push rod (M6) stops at the place where it was moving, and because of this, it is possible to maintain the anti-clutch state. In more detail, when starting from an uphill road or carrying a heavy load, the engine speed increase stops or moves almost simultaneously with the moment of access to the anti-clutch state even when the accelerator pedal (M1) is pressed because the load on the drive shaft is heavy. This slows down and the pushrod M6 is also almost in place. At this time, the driver continues to press the acceleration pedal M1, and thus, the opening angle of the throttle valve is increased, so that a large amount of fuel is supplied into the combustion chamber, so that the output can be smoothly started.

As such, according to the present invention, since the clutch disc connection speed is automatically adjusted by the engine speed or the engine speed ascending speed, the start of the transport vehicle can be made smoothly under any conditions.

2. When pressing the half clutch button

The anti-clutch button 2 stops on the hill for beginners and eliminates the phenomenon of the vehicle being pushed back at the start. When the half-clutch button 2 is pressed, the engine speed increasing means for opening the throttle valve 13 The engine speed is increased, and the clutch disk is positioned in the half clutch state preset by the half clutch setting volume 10. At this time, when the engine speed increases to reach the connection ALMP, the clutch disk is connected.

3. When the reverse button is pressed

When the reverse button data value is input by the input of the reverse button 3, the motor 12 is reversely rotated so that the clutch disk is connected in any state, and accordingly the push rod (5) is pushed by the push rod feed gear M5. Position M6 backward to connect the clutch disk.

4. When the low speed mode button is pressed

The low speed mode button 4 is for the case that the driver frequently presses the brakes when the vehicle is pushed on the road and repeats a short section. When the low speed mode button 4 is pressed, the engine speed As a result, the motor 12 is rotated forward and backward to block the clutch disk when the engine speed is lowered.

As described above, the present invention uses the engine speed (rpm) as a reference for determining the connection point of the clutch disk, and connects the clutch disk only as much as the value corresponding to the engine speed increase value. By stopping, the anti-clutch effect can be applied to the semi-auto clutch vehicle, so that power can be transmitted smoothly. That is, since the RPM ascending speed is sensitive and precisely indicates the load state of the drive shaft, the present invention can more smoothly transmit the power of the vehicle by automatically controlling the clutch according to the RPM.
