Description

Technical Field [0001] The present invention relates to a power transmission apparatus for a compressor,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a power transmission apparatus for a compressor used in an air conditioning system of a vehicle, and more particularly to a power transmission apparatus for a compressor for transmitting rotational force transmitted from an engine of a vehicle to a compressor.

Generally, a compressor used in an air conditioner receives refrigerant from an evaporator and converts the refrigerant into a high-temperature and high-pressure refrigerant gas, and provides the refrigerant gas to a condenser. Among the compressors described above, a compressor used in a vehicle air conditioner is configured to receive a driving force of an engine through a pulley assembly to compress refrigerant.

On the other hand, a conventional vehicle compressor is configured to selectively intermittently transmit the driving force of the engine to the rotary shaft of the compressor using an electromagnetic clutch. However, in the case of the variable capacity type compressor, which is frequently used in recent years, the compression operation is selectively performed by adjusting the inclination angle of the swash plate in accordance with the cooling demand, so that the electromagnetic clutch is not required separately. The power transmitting device for transmitting the power is constituted of a clutchless type.

However, in the compressor of the above-described structure, when the load above the set value is generated, the rotation axis of the compressor is not rotated and the pulley forcibly stops. As a result, the belt that transmits the driving force from the engine slips on the surface of the pulley Which may cause damage to the belt.

Conventionally, a limiter assembly 20 is additionally provided as shown in FIG.

Here, the pulley assembly 10 is configured to be rotated by receiving the drive force of the engine, and has a hollow cylindrical shape, and has a pulley 11 and a pulley 11 (not shown) to which a belt (not shown) And a bearing 12 provided on an inner circumferential surface of the bearing 12.

The limiter assembly 30 is configured to transmit the power of the pulley assembly 10 to the rotary shaft of the compressor. In particular, the limiter assembly 30 normally rotates together with the pulley assembly 10 to rotate the rotary shaft. However, when a torque greater than a set value is generated in the compressor or when the rotary shaft of the compressor can not be rotated, .

The limiter assembly 30 is mounted on the outer wall surface of the pulley 11 constituting the pulley assembly 10 and includes a hub 31 to which a rotary shaft is coupled, a limiter 32 coupled to the hub 31, And a limiter housing 33 which is coupled to the pulley 11 while being installed therein.

The limiter 32 is cut off when the torque of the compressor is higher than a set value or the rotation axis of the compressor can not be rotated and blocks the transmission of the rotational force transmitted from the pulley 11 to the hub 31. [

On the other hand, the pulley included in the power transmission device of the compressor receives power from the engine of the vehicle and transmits the power to the compressor. As described above, the crankshaft of the vehicle engine is accompanied by torque fluctuations during each stroke of intake, compression, . Therefore, the power transmission device of the compressor is generally provided with a separate damper capable of absorbing torque fluctuation of the engine.

As described above, the conventional power transmission device of the clutchless compressor is provided with a separate limiter 32 for blocking the transmission of the driving force in case the rotating shaft of the compressor can not be rotated, and a separate limiter 32 for absorbing the torque fluctuation of the engine A damper is required. Therefore, various problems such as complexity of the device structure and complication of the assembling process due to an increase in the number of parts are accompanied. In addition, there is a disadvantage in that operational reliability can not be satisfied in terms of functions such as limiter breakage and damper torque absorption performance.

SUMMARY OF THE INVENTION The present invention has been made in order to solve the above problems of the prior art, and it is an object of the present invention to provide a damper device capable of preventing power transmission at the time of occurrence of a load exceeding a set value of a compressor without a separate power- The present invention is intended to provide a power transmission device for a compressor that allows a constant torque to be transmitted to a compressor at the time of high-speed rotation of the engine without the need for such a separate torque fluctuation absorbing component.

A power transmission device for a compressor according to an embodiment of the present invention is a power transmission device for transmitting a driving force of a vehicle engine to a compressor, comprising: a hub formed at one end of a rotary shaft of the compressor and rotated integrally with the rotary shaft; A first plate formed integrally with the hub, a permanent magnet formed on the first plate, a pulley rotatably coupled to the compressor and rotated by receiving power from the engine of the vehicle, A second plate that is rotated integrally with the first plate and faces the first plate at a distance so as not to be in contact with the first plate, and a conductor formed in an area facing the permanent magnet of the second plate.

In the power transmission device for a compressor according to an embodiment of the present invention, the permanent magnets may include a plurality of permanent magnets disposed in a circumferential direction on the first plate.

In the power transmission apparatus for a compressor according to the embodiment of the present invention, the plurality of permanent magnets may be disposed at equal intervals.

In the power transmission apparatus for a compressor according to the embodiment of the present invention, the plurality of permanent magnets may have different magnetic poles from the adjacent permanent magnets.

In the power transmission device for a compressor according to an embodiment of the present invention, the first plate may be formed with a permanent magnet receiving groove in which the permanent magnet is received.

In the power transmission device for a compressor according to the embodiment of the present invention, a suction member may be formed on the bottom of the receiving groove.

In the power transmission device for a compressor according to the embodiment of the present invention, the conductor may be formed in an annular shape.

In the power transmission device of the compressor according to the embodiment of the present invention, the second plate may be provided with a conductor receiving groove for receiving the conductor.

In the power transmission device of the compressor according to the embodiment of the present invention, the heat dissipating groove may be formed on the surface of the second plate opposite to the side facing the first plate.

The features and advantages of the present invention will become more apparent from the following detailed description based on the accompanying drawings.

According to the present invention, since the first plate and the second plate transmit power without contacting the first plate and the second plate in the power transmission structure, even if a load greater than a set value is generated in the compressor, abrasion occurs due to breakage or friction of the components The second plate can be slipped relative to the first plate. Therefore, a separate power cut-off component such as a limiter is unnecessary.

In addition, since the first plate and the second plate are not in contact with each other and an eddy current is generated in the conductor to transmit the power, even if there is torque variation in the rotational torque of the engine transmitted to the pulley, It is absorbed in the course of conversion into heat energy to generate heat, and even if there is no separate torque fluctuation absorbing part such as a damper, constant torque can be transmitted to the rotating shaft.

The power transmission device 1 of the compressor according to the embodiment of the present invention includes a hub 210, a first plate 220, a permanent magnet 222, a pulley 230, a second plate 240 ), And a conductor 242.

The hub 210 may be formed at one end of the rotary shaft 120 that is provided in the compressor 100 and is transmitted with driving force transmitted from the engine of the vehicle. The hub 210 may be integrally formed with the rotary shaft 120 and may be coupled to one end of the rotary shaft 120 as a separate component as shown in the figure. The hub 210 formed at one end of the rotary shaft 120 is rotated integrally with the rotary shaft 120. More precisely, the rotational force transmitted to the hub 210 is transmitted to the rotational shaft 120 by the hub 210, and the rotational shaft 120 is integrally rotated together with the hub 210.

The first plate 220 may be in the form of a disc, for example. A through hole 224 through which the hub 210 passes may be formed at the center of the first plate 220. A flange portion 211 formed at one end of the hub 210 and a flange portion 211 The first plate 220 can be formed on the outer surface of the hub 210 by fastening the fastening member 212 around the through hole 224 of the first plate 220. The first plate 220 may be a separate part as shown and may be coupled to the hub 210, but may be integrally formed with the hub 210.

The permanent magnets 222 are formed on the first plate 220, and may be formed of a plurality of cylinders, for example. The plurality of permanent magnets 222 may be spaced apart from each other in the circumferential direction of the first plate 220. The permanent magnet receiving groove 221 for receiving the permanent magnet 222 may be formed on the first plate 220 so as to be accommodated in the receiving groove 221. At this time, the receiving groove 221 may be formed to have a depth such that it does not protrude on the surface of the first plate 220 when the permanent magnet 222 is accommodated. The receiving grooves 221 may be spaced apart from each other in the circumferential direction on the first plate 220. The plurality of permanent magnets 222 may be arranged along the circumferential direction so as to be spaced apart at regular intervals along the circumferential direction. Spaced apart from each other. The plurality of permanent magnets 222 may have different magnetic poles from the adjacent permanent magnets.

In the illustrated embodiment, the receiving groove 221 is formed on the opposite surface of the first plate 220 facing the compressor 100. However, the present invention is not limited thereto. But may be formed on the side facing the compressor 100.

The suction member 223 may be formed on the bottom of the receiving groove 221 to facilitate the assembly of the permanent magnet 222 and to prevent the permanent magnet 222 from being detached from the receiving groove 221. The attracting body 223 may be a ferromagnetic material such as steel, for example, which can attract the permanent magnet 222 and magnetic attraction.

The pulley 230 receives rotational force from the engine of the vehicle. The pulley 230 may be connected to the engine of the vehicle by a power transmitting member such as a belt (not shown). The pulley 230 may be rotatably coupled to one side of the compressor 100, for example, the end of the housing 110, which forms the outer shape of the compressor 100. A bearing 231 may be interposed between the inner circumferential surface of the pulley 230 and the outer circumferential surface of the housing 110 to be rotatably engaged.

The second plate 240 is formed on the pulley 230 and rotates integrally with the pulley 230. The second plate 240 may be formed in a disc shape, for example, and a through hole 244 may be formed in the center so that one end of the hub 210 is exposed to the outside. The second plate 240 may be formed with a coupling leg 245 protruding toward the compressor 100. The coupling member 246 penetrates through the coupling leg 245 and is fastened to the pulley 230, 2 plate 240 and the pulley 230 can be coupled to each other. As the pulley 230 rotates in this way, the second plate 240 also rotates integrally therewith. The spacing 235 between the second plate 240 and the pulley 230 is formed by the length of the coupling leg 245 and the first plate 220 may be disposed in the spacing space 235. A heat dissipating groove 243 may be formed on the opposite side of the second plate 240 facing the first plate 220. The surface area of the second plate 240 may be increased by the heat dissipating groove 243 So that heat generated in the second plate 240 can be easily discharged to the outside.

In the above description, the structure in which the second plate 240 is formed as a separate part and coupled to the pulley 230 has been described, but the present invention is not limited thereto. It is also possible that the second plate 240 and the pulley 230 are integrally formed.

The conductor 242 is formed on the second plate 240 and more specifically on the region facing the permanent magnet 222 of the second plate 240. The conductors 242 may be formed in an annular shape, for example, along the circumferential direction of the second plate 240, or may be formed to be spaced along the circumferential direction of the second plate 240. For example, the second plate 240 may be formed with a conductor receiving groove 241 in which a conductor 242 is received, and the conductor 242 is received in the receiving groove 241 . At this time, the depth of the receiving groove 241 may be such that the conductor 242 does not protrude on the surface of the second plate 240. In the illustrated embodiment, the receiving groove 241 is formed on the surface of the second plate 240 facing the first plate 220. However, the present invention is not limited to this, and it is also possible to form the receiving groove 241 on the opposite side Do. The conductor 242 may be made of a conductive material such as an iron material or an aluminum material.

The first plate 220 and the second plate 240 are disposed to face each other while the first plate 220 is disposed between the second plate 240 and the pulley 230 and the permanent magnet 222 The conductors 242 are also disposed facing each other. At this time, the second plate 240 is disposed at a predetermined distance G without contacting the first plate 220. The spaced distance G may be, for example, 0.05 mm. Accordingly, the power transmission device 1 of the compressor according to the present embodiment is configured such that when the rotational force transmitted from the vehicle engine is transmitted to the rotating shaft 120 through the pulley 230, the second plate 240 and the first plate 220, Which is different from the conventional power transmission device of the conventional compressor.

The operation of the power transmitting apparatus 1 of the compressor according to the present embodiment including the non-contact structure will be described in detail as follows.

The rotational force transmitted from the engine of the vehicle is transmitted to the pulley 230 by a power transmitting member such as a belt. As the pulley 230 is rotated, the second plate 240 formed on the pulley 230 rotates together with the pulley 230. At this time, the conductor 242 facing the permanent magnet 222 rotates with a relative displacement with respect to the permanent magnet 222, thereby changing the magnetic field formed on the conductor 242. As a result, an eddy-current is generated in the conductor 242, and the eddy current is formed so as to generate a magnetic field which interferes with the relative displacement of the conductor 242 with respect to the permanent magnet 222. The rotation torque of the second plate 240 is transmitted to the first plate 220 having the permanent magnet 222. When the first plate 220 rotates, the hub 210 and the rotary shaft 120 ) Are rotated together.

On the other hand, since the driving of the internal combustion engine of the vehicle converts the reciprocating motion of the piston into the rotational motion of the crankshaft during the course of intake, compression, explosion, and exhaust stroke, periodic torque fluctuations occur in the crankshaft . This torque fluctuation is transmitted through the pulley 230 and the second plate 240, and is converted into heat energy as resistance heat due to eddy currents formed in the conductor 242 in accordance with rotation of the second plate. Therefore, the rotational torque transmitted to the first plate 220 can be kept constant. As a result, the power transmission device 1 of the compressor according to the present embodiment does not require a separate component such as a damper for absorbing the above-described torque fluctuation. However, the resistance heat generated in the conductor 242 by the eddy current may damage not only the conductor 242 but also the second plate 240 on which the conductor 242 is formed, and other constituent parts. Therefore, the heat generated in the conductor 242 needs to be easily released to the outside. In this embodiment, the heat dissipation groove 243 is formed in the second plate 240, so that the heat dissipation is facilitated.

When a load equal to or greater than a predetermined value is applied to the compressor 100, the present embodiment is configured such that the first plate 220 and the second plate 240 are separated from each other by a predetermined distance G, The second plate 240 can be slipped in a non-contact state with respect to the first plate 220 without causing breakage or abrasion of the components. For this reason, the power transmission device 1 of the compressor according to the present embodiment can omit components such as the limiter 32 (see Fig. 1) which should be provided in the power transmission device of the conventional compressor.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, It is obvious that the modification or the modification is possible by the person.

It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
