Description

Magnetic clutch for swash plate compressor.

The present invention relates to a magnet clutch for a swash plate type compressor, and more particularly, to an improvement in a fastening structure of a clutch plate for selecting power connection and disconnection between an amateur plate and a driver plate of a magnet clutch.

The swash plate compressor for automobiles is applied to an automobile air conditioning system and is driven by an engine to compress a refrigerant made of a low pressure gas from an evaporator at a high temperature and a high pressure and send it to a condenser.

The swash plate type compressor is installed in the lateral direction of the front and rear frames to fix the swash plate in the middle of the shaft, and a piston through the shoe is installed at the outer periphery of the swash plate, so that the piston reciprocates by the rotating swash plate. Compressive configuration.

In order to rotate the swash plate of the swash plate type compressor, a magnet clutch is provided at the end of the shaft to switch power to select driving of the compressor.

The magnet clutch may be formed at the outer side of the rotor and the coil housing which is inserted with the coil into the insertion groove formed in the rotor and the rotor, which forms a belt groove to receive the engine power, so that the shaft and the bearing may be freely rotated. It consists of a clutch plate which is composed of a tourer and a driver plate and fixed to a shaft.

Conventionally, a combination of an armature plate connected to a rotor and a driver plate fixed to a shaft and driving a compressor is accommodated in a rivet formed by integrally forming a rubber damper and a cap welded to the driver plate to be riveted.

This conventional configuration has problems such as complicated work for forming each part and consequent increase in manufacturing cost.

Therefore, the present invention has been made to solve the above problems as having a configuration that is combined by fastening the armature plate, driver plate, rubber damper, cap and rivets in order to simplify the molding process of each part assembly It aims to improve the performance and contribute to cost reduction.

The swash plate compressor 100 is inclined at a predetermined angle with respect to the axial center of the shaft 12 at the middle of the shaft 12 which is rotated by receiving the power of the engine in the inner central transverse direction of the front and rear frames 10 and 11. The swash plate 13 is fixed, the outer circumference of the swash plate 13 to be connected to the piston 15 through the shoe 14 to the piston 15 is reciprocated by the rotation of the swash plate 13 It is a structure which compresses a refrigerant.

The front end of the shaft 12 is provided with a magnet clutch 20 that receives the engine power to determine whether or not the drive of the shaft 12.

The magnet clutch 20 is inserted into the rotor 22 and the rotor 22 inside the rotor 22 and the rotor 22 which are connected to the front end of the front frame 10 by the bearing 21 and are connected to the engine and the belt by rotation. The cover plate 25 is interposed into the coil housing 24 and the rear surface of the coil housing 24 to prevent the coil housing 24 from being separated.

In front of the rotor 22 is provided with a clutch plate 26 for driving the compressor by connecting to the magnetized rotor, the clutch plate 26 is connected to the rotor 22 and the amateur plate 27 and the shaft ( It consists of a drive plate 28 fixed to 12).

The amateur plate 27 and the driver plate 28 are fastened by the rubber damper 29 and the rivet 30.

Conventionally, the coupling relationship between the armature plate 27 and the driver plate 28 is a rivet 30 integrally formed with the rubber damper 29 as shown in FIGS. 1 to 4 to the drive plate 28. It is accommodated in the welded cap 32 so that the end of the rivet 30 passes through the coupling holes 33 and 34 formed in the driver and the amateur plate 28 and 27, and then rivets the end of the rivet 30. Tighten by

In the conventional construction as described above, since the rivet 30 and the rubber damper 29 must be integrally formed and the driver plate 28 and the cap 32 must be welded and fixed, the manufacturing process of each part is complicated and the cost is increased. It had the above-mentioned problems, such as providing a cause.

In the present invention in view of the above problems, as shown in Figs. 5 to 7, the armature plate 27, the driver plate 28, the rubber damper 29, the cap 32 and the rivet 30 in sequence By riveting by combining has a configuration that does not go through a separate machining or fixing process.

As described above, the lower end surface of the rubber damper 29 has a protrusion 40 having the same diameter as the coupling hole 33 formed in the driver plate 28 so that the flow can be suppressed. do.

The upper surface of the rubber damper 29 is further formed with a cap receiving groove 42 which can accommodate the concave inlet portion 41 of the cap 32 is placed to prevent the risk of deformation during riveting.

The present invention as described above is fastened by sequential coupling without the hassle of forming or fixing each part as in the prior art when fastening the armature plate 27 and the driver plate 28 of the clutch plate 26 This enables not only to improve the overall assembly, but also to simplify the part forming process, thereby reducing the cost.

The present invention as described above can contribute to the improvement of the assembly of the clutch plate as well as has an effect that can contribute to cost reduction.
