CLUTCH ASSEMBLY FOR COMPRESSOR OF AIR CONDITIONER OF VEHICLE REDUCING POWER CONSUMPTION [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a clutch assembly of an air conditioner compressor that transmits power to a compressor that compresses a refrigerant for operating an air conditioner for air conditioning of a vehicle, and more particularly, And the power consumption is reduced so that the power consumption is reduced. [0002] The present invention relates to a clutch assembly for a vehicle air-conditioner compressor.

If the operation of the air conditioner is not required, the power applied to the coil 111 is cut off so that the elastic force of the disc 112 or the elastic force of the disc 112 or the gap between the disc 112 and the rotating shaft 11 The driving force of the engine is prevented from being transmitted to the compressor 10 by separating the disk 112 and the pulley 20 from each other.

Meanwhile, a bearing 21 is provided between the pulley 20 and the rotary shaft 11 so that power is not directly transmitted through the bearing 21.

However, since the clutch assembly of the conventional air conditioning compressor according to the related art as described above is required to keep the disc 112 in contact with the pulley 20 when the compressor is in operation, power is continuously supplied to the coil 111 There is a problem that it must be applied.

Since power is supplied to the coil 111 and the disk 112 is brought into close contact with the pulley 20 to transmit power from the pulley 20 to the compressor 10, 112 must be continuously applied to the pulley 20 so as to be in close contact with the pulley 20, which causes a decrease in the fuel efficiency of the vehicle.

On the other hand, the following prior art document discloses a technique relating to an energy-saving clutch assembly.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a clutch assembly of a vehicle air-conditioner compressor with reduced power consumption according to the present invention will be described in detail with reference to the accompanying drawings.

A clutch assembly of a vehicle air-conditioner compressor in which power consumption is reduced according to the present invention is characterized in that a rotary shaft (11) of a compressor (10) penetrates and is rotated by a drive motor (31) driven by a power source, A rotation plate 33 formed along the circumferential direction and having a slit 33b having a profile formed in a zigzag shape along the axial direction of the rotation axis 11; A housing plate 35 slidably installed in the axial direction of the rotating shaft 11 by a profile of the housing plate 35 and the housing plate 35. The housing plate 35 slides on the rotating plate 33, The housing plate 35 can be connected to the pulley 20 and the rotary shaft 11 at the same time and when the rotary plate 33 is adjacent to the housing plate 35, And when the operation of the air conditioner is requested or when the operation of the air conditioner is requested to be stopped, power is applied to the driving motor 31 to rotate the rotating plate 33 And the housing plate 35 is slid in the axial direction of the rotating shaft 11.

The drive motor 31 is installed at one side of the housing of the compressor 10. The driving motor 31 is operated only while the power is being supplied. The driving motor 31 is powered to operate only when the operation of the air conditioner is started and only when the operation of the air conditioner is stopped. The output shaft of the drive motor 31 is provided with a power transmission means such as a drive gear 32 for transmitting the rotational force of the drive motor 31.

The rotation plate 33 is installed to be rotatable by the drive motor 31. The rotation plate 33 is rotated by the drive motor 31 only when the air conditioner starts to operate and when the air conditioner stops operating.

The rotation plate (33) penetrates the rotary shaft (11) of the compressor (10) in the middle. The rotary plate 33 is installed outside the rotary shaft 11 of the compressor 10 but the inner circumference of the rotary plate 33 is separated from the rotary shaft 11 so as to rotate separately from the rotary shaft 11, .

The rotation plate 33 may be geared to engage with the driving gear 32 along the rotation plate 33 so that the rotation plate 33 can be rotated by the driving motor 31.

On the other hand, an extension 33a extending along the longitudinal direction of the rotary shaft 11 is formed on the inner periphery of the rotary plate 33. [ The extension portion 33a extends toward the pulley 20 from the inner periphery of the rotary plate 33. [

The extension portion 33a is formed with a slit 33b for determining the power transmission according to the rotation of the rotation plate 33. [ The profile of the slit 33b is basically formed along the circumferential direction of the rotary plate 33, but is formed in a zigzag shape along the axial direction of the rotary shaft 11. Since the profile of the slit 33b is formed in a zigzag shape along the axial direction of the rotary shaft 11, the rotary shaft 11 and the pulley 20 are connected or separated.

The housing plate 35 is installed in such a manner that the rotating shaft 11 passes through the center of the housing plate 35 and is slidable along the axial direction of the rotating shaft 11 by the profile of the slit 33b. At this time, the housing plate 35 is slidable along the longitudinal direction of the rotary shaft 11, but does not rotate. If the housing plate 35 rotates, when the rotary plate 33 is rotated together with the rotary plate 33, The guide protrusion 35b does not move along the slit 33b and the housing plate 35 can not slide.

The housing plate 35 is formed with an extended portion 35a whose inner periphery extends along the axial direction of the rotary shaft 11. [ The extended portion 35a formed on the housing plate 35 is formed to be opposite to the extended portion 33a formed on the rotating plate 33 and overlapped with each other. For example, an extension portion 33a of the rotation plate 33 is formed outside the extension portion 35a of the housing plate 35.

On the other hand, the extension portion 35a of the housing plate 35 is formed with a guide protrusion 35b inserted into the slit 33b. The guide protrusion 35b is inserted into the slit 33b so that when the rotation plate 33 rotates, the housing plate 35 moves along the axial direction of the rotation shaft 11 along the profile of the slit 33b .

The profile of the slit 33b is formed in a circumferential direction of the rotation plate 33 and is formed in a zigzag shape along the axial direction of the rotation axis 11. The rotation plate 33 is formed at a predetermined angle, For example, by 90 degrees, the guide protrusion 35b is formed to be maximally spaced from the housing plate 35 in a state of being maximally adjacent to the housing plate 35. [ That is, when the rotation plate 33 is rotated by a predetermined angle of 90 degrees, the housing plate 35 is separated from the rotation plate 33 by a maximum distance from the rotation plate 33 . The housing plate 35 is maximally adjacent to the rotary plate 33 in a state where the housing plate 35 is spaced apart from the rotary plate 33 by a maximum distance. Therefore, the housing plate 35 is adjacent to or spaced from the rotary plate 33 at intervals of 180 degrees.

The outer circumference of the housing plate 35 is formed to extend in a direction opposite to the extending portion. The housing plate 35 has a bent portion formed at an outer periphery thereof so as to be bent to restrain the outer circumference of the contact plate 36. And the outer periphery of the contact plate 36 is restrained by the bent portion.

The sleeve 34 is provided at a position where the rotation plate 33 and the housing plate 35 are located on the rotation shaft 11.

The sleeve 34 is formed in a cylindrical shape so that the inner surface of the sleeve 34 forms a clearance c with the outer surface of the rotating shaft 11. The sleeve 34, the extension 33a of the rotary plate 33 and the extension 35a of the housing plate 35 are disposed outside the rotary shaft 11.

The sleeve 34 is formed with guiding means such that the housing plate 35 does not rotate along the rotary plate 33 but slides along the longitudinal direction of the rotary shaft 11. [ For example, if a guide groove is formed in the sleeve 34 along the longitudinal direction of the sleeve 34 and a guide protrusion is inserted into the guide groove on the inner surface of the housing plate 35, 35 can slide only without rotating.

An end portion of the sleeve 34 adjacent to the rotation plate 33 is formed to extend in a flange shape and is fastened to the housing of the compressor 10.

Therefore, when the rotation plate 33 rotates, the housing plate 35 slides along the longitudinal direction of the rotation shaft 11 only by the profile of the slit 33b, As shown in Fig.

The contact plate 36 is installed inside the housing plate 35. The contact plate 36 is formed in the form of a disk so that when the housing plate 35 is separated from the rotary plate 33, the contact plate 36 is engaged with the pulley 20 and the rotary shaft 11 At the same time, power transmission is possible.

A needle bearing 37 is provided between the contact plate 36 and the housing plate 35 to reduce friction with the housing plate 35 stopped when the contact plate 36 rotates.

5 and 6 must be in contact with the pulley 20 and the rotary shaft 11 at the time of power transmission so that the housing plate 35 is in contact with one side of the contact plate 36, The plate 36 and the side in contact with the rotating shaft 11 are formed to be open.

The ball bearing 38 is sandwiched between the end of the contact plate 36 and the bend of the housing plate 35 to reduce friction.

On the other hand, on the rear surface of the rotation plate 33, when the rotation plate 33 rotates by a predetermined angle, the power applied to the drive motor 31 is cut off.

A contactor 33c is provided on one side of the rotation plate 33, preferably on the rear side of the rotation plate 33. When the contactor 33c is in contact with or contacts with one side of the housing of the compressor 10 And a power cut-off switch 39 for cutting off the power applied to the drive motor 31 are provided.

At this time, the contactor 33c is installed on the rear surface of the rotary plate 33 at a predetermined interval, and the contactor 33c is installed at an interval of the contactor 33c, It is preferable that the housing plate 35 is formed at an angle at which the housing plate 35 is maximally adjacent in a state where the housing plate 35 is maximally spaced apart or at an angle at which the housing plate 35 is maximally spaced from the maximum adjacent state Do. The contactor 33c is also formed at intervals of 90 degrees since the slit 33b is formed such that the profile of the slit 33b is maximally adjacent or spaced apart from the housing plate 35 by 90 degrees every 180 degrees.

The rotary shaft 11 may be provided at the end thereof with a contact portion 11a which is integrally fastened to the rotary shaft 11. There is no portion where the rotation shaft 11 and the contact plate 36 can contact with each other when the contact plate 36 is passed through the inside of the rotation shaft 11 so that the contact portions 11a So that the end portion of the contact portion 11a can be brought into contact with the contact plate 36.

The operation of the clutch assembly of the vehicle air-conditioner compressor having the above-described configuration with reduced power consumption according to the present invention will now be described.

First, the relationship between the rotation plate 33 and the housing plate 35 will be described with reference to Figs. 7A to 7E.

7A is a state in which the housing plate 35 is maximally adjacent to the rotary plate 33 in a state before the air conditioner is operated. In this state, when power is applied to the drive motor 31 for the operation of the air conditioner, the rotation plate 33 starts to rotate, and the contact of the clutch assembly of the present invention starts.

When the rotation plate 33 starts to rotate, the guide protrusion 35b moves in the axial direction of the rotation shaft 11 by the profile of the slit 33b, And starts to separate from the rotary plate 33 (see Fig. 7B).

Subsequently, when the rotation plate 33 rotates, the housing plate 35 is maximally spaced from the rotation plate 33 (see FIG. 7C). When the housing plate 35 is maximally spaced from the rotating plate 33, the clutch assembly is brought into a complete state, and the compressor 10 is driven to operate the air conditioner. At this time, the power applied to the driving motor 31 is cut off, and when the air conditioner is operating, the state shown in FIG. 7C is maintained.

When the operation stop of the air conditioner is requested, power is again applied to the driving motor 31 to rotate the rotation plate 33 again. When the rotation plate 33 rotates, the guide protrusion 35b moves in a direction opposite to that at the time of contacting the clutch assembly so that the housing plate 35 is adjacent to the rotation plate 33 (see FIG. 7D) .

When the rotation plate 33 continues to rotate and the housing plate 35 is again maximally adjacent to the rotation plate 33, the disengagement of the clutch assembly is completed, do. In addition, the power supplied to the drive motor 31 is cut off, and the state shown in FIG. 7E is continuously maintained.

9A and 9B show the contact relationship of the contact plate 36 in the disengaged state of the clutch assembly. 7A or 7E, the contact plate 36 is pressed against the pulley 20 and the rotary shaft 11 at the same time in a state in which the rotary plate 33 and the rotary plate 33 are maximally adjacent to each other, The compressor 10 is not driven because the pulley 20 rotates but the rotational force of the pulley 20 can not be transmitted to the rotary shaft 11 because the pulley 20 is separated at intervals.

10A and 10B show the contact state of the contact plate 36 in the connected state of the clutch assembly. The contact plate 36 is simultaneously brought into contact with the pulley 20 and the rotary shaft 11 in a state where the rotary plate 33 and the rotary plate 33 are spaced apart from each other as shown in FIG. The housing plate 35 pushes the contact plate 36 toward the pulley 20 and the contact portion 11a when the housing plate 35 is spaced apart from the rotation plate 33 as much as possible. When the contact plate 36 is pushed toward the pulley 20 and the contact portion 11a so that one surface of the contact plate 36 is supported by the housing plate 35, 20 and the contact portion 11a at the same time.

9B, the contact plate 36 is separated from the pulley 20 and the rotation shaft (contact portion). However, when the housing plate 35 moves from L1 to L2 The contact plate 36 contacts the pulley 20 and the rotary shaft (contact portion) at the same time to transmit power, as shown in A 'and B' of FIG. 10B.

Accordingly, when the pulley 20 rotates, the contact plate 36 also rotates, and the contact portion 11a also rotates by the rotation of the contact plate 36. [ Accordingly, the rotational force of the pulley 20 is transmitted to the rotary shaft 11 through the contact plate 36, the compressor 10 is driven, and the air conditioner operates to enable cooling.

A contactor 33c is formed on the rotation plate 33 for each contact-separation angle of the clutch assembly. When the rotation plate 33 completes contact or separation of the clutch assembly, (39) to block power applied to the drive motor (31).

13, the clutch assembly of the automotive air-conditioner compressor in which the power consumption according to the present invention is reduced is driven only when the air conditioner starts operating and when the operation of the air conditioner is stopped, And the power supply is not required in the remaining sections. In the prior art, when the air conditioner is in operation, power must be continuously applied to the coil. However, in the present invention, power is supplied only when the air conditioner starts and stops.
