Description
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

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
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.
In the power transmission device of the compressor according to the embodiment of the present invention, the permanent magnet is accommodated in the permanent magnet accommodating groove formed in the first plate so as not to protrude on the surface of the first plate facing the second plate And the conductor may be accommodated in a conductor receiving groove formed in the second plate so as not to protrude from the surface of the second plate 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.
