Abstract

PURPOSE: A device for controlling hydraulic pressure of a clutch is provided to control temporary unbalance of pressure or a flow produced by an actuating fluid. CONSTITUTION: A clutch includes a clutch pedal, a master cylinder connected to one side of the clutch pedal and moved by operation of the clutch pedal, a clutch release cylinder connected to the master cylinder through a connecting pipe, and a clutch release fork connected to the release cylinder and operated by pressure of an actuating fluid produced from the master cylinder. A device for controlling hydraulic pressure of the clutch comprises upper and lower housings(9,11), each communicated to an upper connecting pipe(10) and a lower connecting pipe(12), and a partition plate(13), interposed between the upper and lower housings. One expanding pipe(13-2) is bored on a side of the inside of the partition plate and plural orifices(13-1) are bored on the other side. Thus, vibration is reduced and installation space is sharply reduced.

Description

Hydraulic control device of clutch {APPARATUS FOR CONTROLLING AN OIL PRESSURE IN A CLUTCH}

The present invention relates to a hydraulic control device of the clutch, and more particularly, to improve the operating performance by reducing the operating deviation by improving the surge tank that can replace the hydraulic damper for controlling the release pressure of the automobile clutch. A hydraulic control device of a clutch.

CLUTCH (1) of the vehicle is provided between the flywheel and the input shaft of the transmission (TRANSMISSION) to selectively control the power of the engine transmitted to the transmission, when starting the engine or shifting the gear of the transmission When the engine is disconnected, and when the oscillation, the power of the engine is gradually connected.

In general, the hydraulic clutch operating mechanism attached to the clutch (1) of the vehicle includes a clutch pedal (2), a clutch master cylinder (3), a clutch release cylinder (CLUTCH RELEASE CYLINDER) ( 4), a clutch release fork (CLUTCH RELEASE FORK) 5 and a connecting pipe 6.

1 is a perspective view showing the structure of a conventional hydraulic clutch operating mechanism, wherein when the driver presses the clutch pedal 2, hydraulic pressure is generated in the clutch master cylinder 3, and the clutch release cylinder 4 is operated using the hydraulic pressure. do.

The clutch release cylinder 4 hydraulically pushes the clutch release fork 5 to operate the clutch 1.

At this time, the hydraulic clutch operation mechanism attenuates the surging phenomenon, which is a temporary imbalance of pressure or flow rate generated in the connection pipe 6 by a damper 7 connected to the connection pipe 6 or the like.

However, the damper 7 of the conventional hydraulic clutch operating mechanism as described above is bulky and has difficulty in securing a mounting space, and the damper 7 merely enlarges the cross-sectional area and volume of the connecting pipe 6. There was a problem that can only be effected.

The present invention has been made in view of the above-described problems of the prior art, and has been created to solve this problem. By connecting a surge tank to a connection pipe connecting a hydraulic clutch operating mechanism, a temporary pressure or flow rate generated inside the connection pipe is generated. It is an object of the present invention to provide a hydraulic control device of a clutch to adjust an imbalance.

The above-described object of the present invention is a clutch pedal located below the driver's seat, a master cylinder connected to one side of the clutch pedal and flown by the operation of the clutch pedal, a clutch release cylinder connected to the master cylinder via a connecting pipe, A clutch equipped with a clutch release fork connected to the release cylinder and operated by the pressure of a working fluid generated from the master cylinder, the clutch being connected to an upper connection pipe and a lower connection pipe respectively inserted and connected between the connection pipes. An upper housing and a lower housing; Interposed between the upper housing and the lower housing is fixed by the expansion and the inner side is perforated by a pipe and the other side is achieved by configuring a plurality of orifices perforated.

Hereinafter, a preferred embodiment according to the present invention will be described in more detail on the basis of the accompanying drawings.

Figure 2 is an exploded perspective view and perspective view of the clutch hydraulic control device according to the present invention, the damper (7) to the connecting pipe (6) of the hydraulic clutch operating mechanism shown in FIG. Connect as a substitute.

The surge tank 8 is formed of a hat-shaped upper housing 9 and a lower housing 11, and a circular diaphragm 13 is inserted therebetween and then fixed by welding.

The upper housing 9 and the lower housing 11 are formed in the upper connecting pipe 10 and the lower connecting pipe 12 to communicate with each other vertically, wherein the upper connecting pipe 10 and the lower connecting pipe 12 Are staggered.

The diaphragm 13 has a plurality of drilling tools penetrating up and down inside one side to form an orifice 13-1, and an enlarged pipe 13-2 penetrating up and down inside the other side.

The present invention made up of such a configuration works as follows.

When the hydraulic clutch operating mechanism is actuated, the pulsating wave is transmitted by the working fluid in the connecting pipe 6 to which it is connected.

This pulsation wave is transmitted through the connection pipe 6 in the surge tank 8 according to the present invention, the pulsation wave of the working fluid thus transmitted is an orifice 13-1 formed in the diaphragm 13 of the surge tank 8. And the expansion tube 13-2 decrease the natural frequency of the pulsating wave, thereby reducing vibration.

As described in detail above, the present invention can adjust the temporary imbalance of the pressure or flow rate generated by the working fluid by the orifice and expansion of the diaphragm in the surge tank can be attenuated the vibration generated accordingly In addition, it provides an effect that can significantly reduce the installation space.
