Two stages locking structure for a clutch operating mechanism of an automobile}

The present invention relates to a two-stage locking structure of a clutch operating mechanism for automobiles, and more particularly, to a conventional power transmission / disengagement section (first locking area) and harder when the vehicle is put on a clutch pedal in an idle state. The present invention relates to a two-stage locking structure of a clutch operation mechanism for a vehicle, which is capable of reaching a neutral section (second locking region) when the clutch pedal is removed to ensure a neutral state of the vehicle.

In general, a vehicle is provided with a power transmission device for transmitting the power generated from the engine to the driving wheel, and such a power transmission device transfers the power generated from the engine to the engine → clutch → transmission (T / M) → propulsion shaft → longitudinal It is transferred in the order of reduction gear → liquid shaft → driving wheel.

The clutch operating mechanism is a component that transmits or blocks power generated from an engine to a transmission. A cable type clutch operated by transmitting a pedal operating force to a release lever through a cable, and hydraulic pressure to lighten the operation of the clutch pedal. It is divided into a hydraulic clutch that operates the clutch by generating a.

In particular, the hydraulic clutch is, as shown in Figure 2, the clutch pedal 100 for generating the operating force, the master cylinder 200 for generating the hydraulic pressure by the pedal force, and thus generated It comprises a release cylinder 300 and the release fork 310 for contacting or non-contacting the clutch plate by hydraulic pressure.

In addition, the release cylinder 300 connected to the master cylinder 200 is provided with a booster 320 so that the operation of the release fork 310 is easily performed, and the booster 320 has a release fork 310. Pneumatic line 400 having a predetermined pressure is connected to facilitate the operation of the.

The hydraulic clutch operating mechanism configured as described above generates the hydraulic pressure by operating the master cylinder 200 as the push rod 210 opens the clutch pedal 100, and is provided from the pneumatic line 400 together with the hydraulic pressure. By operating the release fork 310 by the pneumatic pressure is to isolate the clutch from the engine to cut off the power.

However, the conventional clutch operating mechanism removes the gear and removes the clutch pedal in order to block power transmission and to keep the engine idle when waiting for a signal, such as at an intersection, where each component is rotated by the engine speed rotating at the idle speed. The field (from the flywheel of the engine to the idle gear of the transmission) receives an excessive amount of inertia and, in addition, the inertia becomes higher due to the increase in viscosity during transmission oil cooling. In addition, the idler gear rotation on the transmission side becomes unstable due to instability of the engine low idle rpm, so that noise is generated, and thus an improvement is required.

This is caused by the excessive increase in inertia and viscosity, resulting in poor driver fuel economy and vehicle marketability due to poor fuel economy and neutral noise caused by transmission gear-out (with clutch pedal off). Was done.

The present invention has been devised in view of this point, so that the clutch pedal to shut off or transmit power normally in the first locking area, and to keep the power cut off when the idle period is long, such as the stop state at the intersection. As the second locking zone is divided into two locking zones and the clutch pedals are stiffened again, the locking is released, thereby improving fuel economy in the engine idle state and further reducing the noise generated in the idle state. It is an object of the present invention to provide a two-stage locking structure of an automobile clutch operation mechanism.

In addition, the second rod is characterized in that the two-stage locking is released at 13 ~ 15kg of the stepping force applied through the clutch pedal in the state in which the bidirectional locking ball is released.

Hereinafter, the configuration and operation of the present invention with reference to the accompanying drawings.

1A to 1F are cross-sectional views showing an operating state of a two-stage locking structure according to the present invention, and reference numeral 10 denotes a push rod of a master cylinder.

The present invention is equipped with a two-stage locking structure having a conventional clutch operating zone and a two-stage locking zone by the pedal pedal effort on the push rod 10, so that the clutch pedal is a conventional clutch when the engine idle state lasts for a long time. The push rod 10 is locked by stepping harder on the stepping force for manipulation, and the locking is released by a stronger stepping force than this.

Here, the two-stage locking structure wraps the entire outer circumferential surface of the push rod 10 with a predetermined width, and is fixed to the master cylinder 20, and the push rod receives the elastic support inside the body 20, respectively. A pair of actuating rods 21a and 21b mounted to be able to be stored / drawn vertically on the surface of 10 and a pair of actuating rods 21 installed horizontally with the push rod 10 inside the body 20. And bidirectional ball mechanism 22 to selectively limit the operation of the < RTI ID = 0.0 >

In particular, each of the actuating rods 21a and 21b is formed on the outer circumferential surface thereof so as to be fixed by the bidirectional ball mechanism 23, respectively, and the actuating recesses 23 are formed on the actuating rods 21a and 21b. 21b) is configured to be able to be engaged by the bidirectional ball mechanism 23 in a state completely housed in the body 20.

In addition, the operating rods 21a and 21b are formed with sliding surfaces 24a and 24b outwardly at lower ends protruding to the outside of the body 20, which are described later by the pedaling force applied to the clutch pedal. Sliding is performed along the locking section, which will be described later.

The locking ball mechanism is provided with two balls (27a, 27b), which are inserted and locked in the fixing grooves (23) of each of the operation rods (21a, 21b) described above, and springs inserted between the two balls. It consists of 26.

In this locking ball mechanism, the two balls 27a and 27b are always urged by the spring 26 to pressurize the outer circumferential surface of each of the operating rods 21a and 21b. In particular, the balls 27a and 27b are According to the up and down position of the operating rod (21a, 21b) is selectively fitted into the fixing groove 23 to fix the position.

In particular, the tension of the two springs 25a and 25 supporting the pair of actuating rods 21a and 21b and the spring 26 of the locking ball mechanism are the springs 25a and 25b of the actuating rods 21a and 21b. > Spring 26 when the bidirectional locking ball is locked on either side> Spring 25a, 25b of each operating rod 21a, 21b when compressed to the maximum> Spring when both directions are locked ( It is formed in the order of 26, which will be described together with the locking area to be described later.

The clutch operating mechanism made in this way includes a locking section 11 formed on the surface of the push rod 10.

The locking section 11, as shown in the accompanying drawings, Figures 1a to 1f, in the inverted trapezoidal shape with respect to the surface of the push rod 10 is formed a sliding surface, in particular the length of the bottom surface As shown in FIG. 1C, each of the actuating rods 21a and 21b is cut into a length that can be accommodated simultaneously while being drawn out from the body 20.

In addition, the locking section 11 is formed on the bottom surface of the locking projection 12 of the right angle trapezoidal shape to a height lower than the height of this section is formed.

In particular, the locking protrusion 12 is formed by being pushed to the outer portion of the push rod 10 (the portion in which the linkage connected to the clutch pedal is connected to the right side in FIG. 1), wherein the locking protrusion 12 is formed. The first operating rod 21 a is completely received between the right sliding surface and the vertical surface of the locking section 11 to be formed in a position where it can be fixed.

As the locking projection 12 is formed in this way, the above-described locking section 11 is divided into one-stage operation section a and two-stage operation section b on the left and right sides of the section, respectively.

Hereinafter, the correlation between the respective operation sections a and b, the springs 25a, 25b and 26 and the operation rods 21a and 21b will be described with reference to the accompanying drawings.

First, when the clutch operation is normally performed when shifting by shifting the clutch pedal within a range of a predetermined force (about 8 to 10 kg), the two-stage locking structure is shown in FIG. The operating rod 21a is withdrawn from the body 10 and positioned in the first stage operating section a, and the second operating rod 21b is positioned above the push rod 10.

In this case, the first actuating rod 21a moves along the first actuating section (a) and is ready for shifting. In the accompanying drawings, FIG. 1A shows a state in which no stepping force is applied. 1b shows a state in which the maximum effort (about 8 to 10 kg) is applied.

At this time, since the tension of the first actuating rod 21a is greater than the tension of the spring 26 of the locking ball mechanism, the tension of the first actuating rod 21a becomes free to allow the protrusion of the first actuating rod 21a to protrude to the outside of the body 20. Since it is spread over the outer circumferential surface of the push rod 10 is completely received into the body 20 is to be fixed by the ball 27b receiving the elasticity of the spring 26 of the bidirectional locking mechanism.

In such a state, the driver can freely transmit or block power using the clutch.

If a situation in which the driving car has to wait for a predetermined time, for example, waiting for a signal at an intersection or the like, occurs, the position is fixed at the place where the push rod 10 separates the clutch through a two-stage locking structure. Will let you.

When the clutch pedal is attached in FIG. 1A as described above, the clutch pedal is in the same state as in FIG. 1B. In this situation, the clutch pedal is tightened with a stronger force (about 13 to 15 kg in the present invention).

Here, the strength of the pedal force is for the driver to easily grasp the double locking state as compared with the strength of the pedal force normally used when operating the clutch pedal.

When a step of about 13 to 15 kg strength is applied to the push rod 10, the push rod 10 is moved from the right side to the left side of the accompanying drawings, so that the second operation rod 21b is operated in the first stage. Since the force of the spring 25b is greater than the tension of the spring 26 of the bidirectional locking structure, the second actuating rod 21b is positioned as shown in FIG. It is in close contact with the left end of the first operation section (a).

At the same time, as the push rod 10 is pushed from the right side to the left side of the first operating rod 21a, the sliding surface 24a rises along the inclined surface of the locking protrusion 12, and the locking protrusion 12 As shown in FIG. 1C, the rod rod 10 may be prevented from returning to the original position even when the clutch pedal is removed.

On the other hand, the locking structure fixed in two stages as described above, the clutch pedal in order to transmit power again, such as when the signal is changed at the intersection.

At this time, the stepping force for clutching the clutch pedal is to hold the clutch pedal with a force greater than the stepping force (13-15 kg) when the two-stage locking.

Accordingly, the push rod 10 moves further to the left as shown in FIG. 1D, and at the same time, the first actuating rod 21 a rises above the outer circumferential surface of the push rod 10.

Accordingly, the first actuating rod 21a is locked by the ball 27a under tension of the spring 26 of the locking ball mechanism, and the second actuating rod 21b is free. .

In this situation, when the clutch is shifted and the clutch pedal is released, the push rod 10 moves to the right as shown in FIG. 1E.

At this time, the second actuating rod 21b moves along the first stage operating section a and then rises along the sliding surface on the left side. At the same time, the first actuating rod 21a has a step force of the spring 25a. Attached drawing that is first drawn out along the inclined surface of the locking projection 12 while being drawn out of the body 20 while winning the spring 26 of the locking ball mechanism, as shown in FIG. 1F. It will come back to the state.

Therefore, the first actuating rod 21a is returned to its original state by deviating from the second actuating section b.

As described above, the present invention uses a two-stage locking structure, when the clutch operation is not continued for a predetermined time as well as power transmission and interruption during normal clutch shifting according to the strength of the pedal pedal's pedal strength, for example, an intersection In the case of the signal dash at, the locking is performed by using a two-stage locking structure, and the locking thus obtained is configured to be released by more sensitive force, thereby obtaining the following effects.

1) Secondary neutrality can be secured by excluding various gears, transmission oil viscosity, and inertia force of the clutch disk mechanism that make up the transmission when the engine is idle.

2) As a result, it is possible to improve fuel economy in the idle state, which takes up a large proportion of fuel economy in the city.

3) In addition to reducing the noise generated when the engine is idle, the driver does not have to operate the clutch directly, so that the driver can feel the vibration transmitted through the clutch operation mechanism, thereby improving the riding comfort.
