Description

Engine pulley cleaning system with improved durability}

The present invention prevents corrosion due to the potential difference between the pulley and the hub by placing a washer on the pulley applied to the engine to prevent direct contact with the hub, and by applying a coating material to prevent contact to the hub in contact with the washer, This relates to an engine pulley cleaning system with improved durability that can more stably prevent corrosion due to potential differences.

Generally, a compressor used in a vehicle air conditioning system performs the function of sucking refrigerant vaporized in an evaporator, compressing the sucked refrigerant, and discharging the compressed refrigerant.

An example of such a compressor is a compressor employing a pulley assembly that omits an electronic clutch for connecting and blocking the power of a vehicle engine.

Omitting the electronic clutch from the pulley assembly is advantageous in that it can eliminate discomfort to the occupants due to shock during on/off, which is a disadvantage of the electronic clutch.

Typically, a compressor always transmits engine power, so its pumping capacity can vary depending on the cooling load of the vehicle air conditioning system.

The pulley assembly applied to a typical compressor consists of a pulley that rotates by receiving power from the vehicle's engine, and a hub assembly that transmits the rotational force of the pulley to the drive shaft of the compressor.

Therefore, when the pulley rotates, the rotational force is transmitted to the drive shaft of the compressor by the hub assembly and the compressor is driven.

Then, power is transmitted from the vehicle engine through the unwinding belt.

Specifically, the hub assembly includes an inner hub disposed on one side of the pulley and connected to the drive shaft of the compressor, an outer hub that is connected to the inner hub and rotates, and an outer hub that rotates when the compressor is inoperable. It consists of a limiter connected between the inner hub and the outer hub to prevent breakage.

The hub assembly configured in this way serves as a medium that allows the drive shaft of the compressor to rotate in conjunction with the rotational force of the pulley.

Accordingly, the compressor operates to supply refrigerant by the rotational force of the pulley.

Meanwhile, when the compressor is inoperable, the limiter of the hub assembly is broken to cut off the power transmitted from the pulley to the drive shaft, thereby preventing damage to other components (belts) linked to the compressor or engine overload.

However, in the prior art, because the pulley and the hub assembly are coupled so as to be in direct contact, there is a problem in that wear, corrosion, etc. occur due to potential difference when the pulley and the hub assembly are rotated.

Meanwhile, the above-mentioned background technology is technical information that the inventor possessed for deriving the present invention or acquired in the process of deriving the present invention, and cannot necessarily be said to be known technology disclosed to the general public before filing the application for the present invention. .

That is, the first coil spring 48a and the second coil spring 48b repeatedly compress and expand due to the pulley portion 10 colliding with the first collision plate 46 and the second collision plate 47, respectively. Therefore, the pulley portion 10 is repeatedly bounced against the first collision plate 46 and the second collision plate 47, which allows foreign substances stuck on the outer and inner surfaces of the pulley portion 10 to be shaken off. , Foreign substances separated from the pulley portion 10 are sucked in by the intake fan and discharged to the outside of the box portion 41.

In particular, when the pulley portion 10 is bounced against the first collision plate 46 and the second collision plate 47, it repeatedly rotates in the left and right directions like a pendulum due to the rotation axis and is repeatedly tilted.

That is, when the pulley portion 10 is rotated in the direction of the first collision plate 46, only the lower area on the right side is tilted so as to collide with the first collision plate 46, and the pulley portion 10 is tilted in the direction of the second collision plate 47. When rotated, only the lower area on the left side is tilted to fill the second collision plate 47, so foreign substances present on the belt grooves 10a formed between the gear teeth 11 are discharged by vibration. It can be made to fall.

In addition, when the pulley portion 10 is tilted to the left and right, the suction force of the intake fan also acts between the gear teeth 11, so foreign substances existing on the belt groove 10a are easily sucked into the box portion 41. ) can be discharged to the outside.

Specifically, when the integrated operation button is pressed, the first forward and backward driving cylinders 57 advance the first connection bar 55 and position the first operation bars 54 in the belt grooves 10a, respectively.

Thereafter, the motor 53 and the second solenoid 56 operate to rotate the pulley portion 10 in the forward or reverse direction, and the second solenoid 56 repeatedly moves the first connecting bar 55 for a preset time. It moves forward and backward.

As a result, the first brushes 541 are repeatedly moved forward and backward, generating friction with the outer surface of the pulley portion 10 and scraping foreign substances.

And, foreign matter separated from the pulley portion 10 by the operation of the first brushes 541 is discharged to the outside of the first additional box portion 51 by the first additional discharge fan 50c.

At this time, the first operating bars 54 repeatedly move forward and backward in place, but since the motor 53 continues to rotate the pulley part 10 in the forward or reverse direction, the entire outer periphery of the pulley part 10 is scraped in place. This removes foreign substances.

Even when the first operating bar 54 is positioned in the belt groove 10a without the second solenoid 56, the first brush 541 is moved to the pulley portion by rotation of the pulley portion 10 by the motor 53. It is possible to scrape foreign substances by generating sufficient friction with the outer surface of the pulley portion (10), but when the first operating bar (54) is moved forward and backward through the second solenoid (56), the first brush against the outer surface of the pulley portion (10) By further increasing the friction force of (541), efficient scraping can be achieved.

Then, when a preset time (which may be about 1 to 5 minutes) elapses, the operation of the second solenoid 56 is stopped and the first forward and backward driving cylinder 57 moves the first connection bar 55 backward. to pull out the first operating bars 54 from the belt grooves 10a.

Thereafter, the second forward and backward driving cylinders 50b advance the second connecting bar 59 to position the second operating bars 58 in the belt grooves 10a, respectively.

At this time, the motor 53 may be programmed to continue operating, or may be programmed to temporarily stop until the second operating bars 58 are located in the belt grooves 10a and then operate again.

The pulley portion 10 rotates in the forward or reverse direction, and the third solenoid 50a repeatedly moves the second connection bar 59 forward and backward for a preset time (which may be about 1 to 5 minutes).

Because of this, the second brushes 581 are also repeatedly moved forward and backward, generating friction with one side of the gear teeth 11 and scraping foreign substances.

And, foreign substances separated from the pulley portion 10 by the operation of the second brushes 581 are discharged to the outside of the first additional box portion 51 by the first additional discharge fan 50c.

At this time, the second operating bars 58 repeat forward and backward movements in place, but because the motor 53 continues to rotate the pulley part 10 in the forward or reverse direction, the entire outer periphery of the pulley part 10 is scraped in place. This removes foreign substances.

Even when the second operating bar 58 is positioned in each belt groove 10a without the third solenoid 50a, the second brush 581 is geared by rotation of the pulley portion 10 by the motor 53. It is possible to scrape foreign substances by generating sufficient friction with the outer surface of (11), but when the second operating bar (58) is moved forward and backward through the third solenoid (50a), the second brush (581) on the gear tooth (11) ) can be further increased to ensure efficient scraping.

Meanwhile, after foreign substances are secondarily removed from the pulley unit 10 through the external scraper unit 50, the inner surface of the pulley unit 10 is scraped through the internal scraper unit 60.

The internal scraper unit 60 is spaced apart from the external scraper unit 50 at a predetermined distance to one side.

The internal scraper includes a second additional box part 61, a mounting cap 62, an additional motor 63, a third operating bar 64, and a fourth solenoid ( 65) and a lifting cylinder 66.

The second additional box portion 61 has an open upper surface and a receiving space in which the pulley portion 10 is accommodated is formed therein.

A discharge hole 61a is formed on the bottom of the second additional box portion 61 to discharge foreign substances removed from the pulley portion 10.

Both sides of the bottom of the second additional box portion 61 may be supported by a pair of additional support portions 67.

Between the additional support parts 67, an additional seating part 68 is disposed, which is spaced at a predetermined distance below the discharge hole 61a of the second additional box part 61, and on which the second additional discharge fan 69, which will be described later, is seated. do.

The mounting cap 62 has an open bottom, and an empty space is formed inside to accommodate the upper side of the pulley portion 10.

The mounting cap 62 may be made of rubber or silicone material with an excellent coefficient of friction to prevent the pulley portion 10 from being separated.

At this time, the mounting cap 62 may be made of a metal material, and a cylindrical mounting pipe made of rubber or silicone may be mounted on the inner periphery.

Since the mounting pipe is mounted in close contact with the outer periphery of the pulley portion 10, it is possible to prevent the pulley portion 10 from being separated.

The axis of the additional motor 63 is coupled to the upper surface of the mounting cap 62.

As an example, the axis of the additional motor 63 may be directly coupled to the mounting cap 62.

As another example, although not shown in the drawing, the shaft of the additional motor 63 and the mounting cap 62 may be coupled through a coupler.

Since the coupling of the shaft of the additional motor 63 and the mounting cap 62 is the same as the method of coupling the coupler and the second mounting block 52 described above, detailed description will be omitted.

When the additional motor 63 operates, the mounting cap 62 and the pulley portion 10 rotate together.

The third operating bar 64 faces the mounting cap 62 with the pulley portion 10 interposed therebetween.

The third operating bar 64 is accommodated in the inner space of the pulley portion 10 through the lower open portion of the pulley portion 10.

A plurality of third brushes 641 for scraping the inner surface of the pulley portion 10 are formed at regular intervals along the circumferential surface and the longitudinal direction of the third operating bar 64.

The third operating bar 64 is formed to have the same length as the pulley portion 10.

The plunger of the fourth solenoid 65 is coupled to the bottom of the third operating bar 64.

The fourth solenoid 65 moves the third operation bar 64 on the inner space of the pulley part 10 so that the third brush 641 scrapes the inner surface of the pulley part 10 rotated by the additional motor 63. Raise and reverse repeatedly.

The fourth solenoid 65 is seated on the upper surface of the lifting bar 60a.

The lifting cylinder 66 is disposed on the bottom surface of the box portion 41. The lifting cylinder 66 raises or lowers the lifting bar 60a to accommodate the third operating bar 64 in the inner space of the pulley portion 10 or to remove it.

The third operating bar 64 is formed to have the same length as the pulley portion 10 or is formed to have a longer length than the pulley portion 10.

Accordingly, the third brushes 641 are evenly distributed and come into contact with the entire inner surface of the pulley portion 10.

The internal scraper unit 60 may further include a second additional discharge fan 69 that is the same as the first additional discharge fan 50c.

The second additional discharge fan 69 discharges foreign substances separated from the pulley portion 10 to the outside of the second additional box portion 61 through a suction operation while seated on the additional seating portion 68.

In the lifting bar 60a, a plurality of passing holes may be formed at regular intervals for passing foreign substances separated from the inner surface of the pulley portion 10 by the third brush 641.

Next, the operation of the internal scraper unit 60 described above will be described.

On the outer surface of the second additional box portion 61, an additional motor 63, a fourth solenoid 65, a second additional discharge fan 69, and a lifting cylinder 66 are provided with power and operated simultaneously. An operation button, an integrated stop button to stop the operation of the additional motor 63, the fourth solenoid 65, the second additional discharge fan 69, and the lifting cylinder 66 are provided, respectively.

First, the mounting cap 62 is mounted on the upper side of the pulley portion 10, and then an operation signal is applied by pressing each of the integrated operation buttons described above.

At this time, the engine pulley cleaning system 1 with improved durability according to an embodiment of the present invention includes a lifting cylinder 66, a second additional discharge fan 69, an additional motor 63, and a fourth solenoid 65. and operate sequentially, and when a preset time elapses, the operation of the second additional discharge fan 69, the fourth solenoid 65, and the additional motor 63 are stopped, and the lifting cylinder 66 is operated by the fourth solenoid 65. ) is programmed to descend.

Specifically, when the integrated operation button is pressed, the lifting cylinder 66 raises the fourth solenoid 65 to accommodate the third operation bar 64 in the inner space of the pulley portion 10.

Thereafter, the additional motor 63 and the fourth solenoid 65 operate to rotate the pulley portion 10 in the forward or reverse direction, and the fourth solenoid 65 repeatedly operates the third operation bar 64 for a preset time. It rises and falls.

As a result, the third brushes 641 are repeatedly raised and lowered to scrape foreign substances while generating friction with the inner surface of the pulley portion 10.

And, foreign substances separated from the pulley portion 10 by the operation of the third brushes 641 are discharged to the outside of the second additional box portion 61 by the second additional discharge fan 69.

Even without the third operating bar 64 and the fourth solenoid 65, the third brush 641 generates sufficient friction with the inner surface of the pulley portion 10 by rotation of the pulley portion 10 by the additional motor 63. However, if the third operation bar 64 is moved forward and backward through the fourth solenoid 65, the friction force of the third brush 641 on the outer surface of the pulley portion 10 is increased to increase efficiency. Scraping can be done.

Then, when a preset time (which may be about 1 to 5 minutes) elapses, the operation of the fourth solenoid 65 is stopped and the lifting cylinder 66 lowers the third operating bar 64 to lower the pulley portion 10. ) is drawn to the outside of.

Therefore, the pulley portion 10 can be separated from the mounting cap 62 and then installed in the engine.
