Description
Technical field
The utility model relates to a kind of magnetic clutch, a kind of specifically automobile air conditioner electromagnetic clutch with dust-proof cover.
Background technique
Automobile air conditioner clutch is a power transmitting deice between motor car engine and the automobile air conditioner compressor, and motor car engine drives the automobile air conditioner compressor operation by air conditioning clutch.Automobile air conditioner clutch is divided into magnetic clutch and non-magnetic clutch two big classes, and wherein, most automobile is selected magnetic clutch for use.
Magnetic clutch comprises following five classes: dry type monolithic magnetic clutch, dry-type multidisc electromagnetic clutch, wet type multi-disc electromagnetic clutch, magnetic magnetic clutch, slip type magnetic clutch.Automobile air conditioner electromagnetic clutch is generally dry type monolithic magnetic clutch, as Chinese patent application 02229533.X, 200310108374.7, disclosed this type of magnetic clutchs that are such as 200620127439.1.
Automobile air conditioner electromagnetic clutch is installed on compressor main shaft and the protecgulum, is made of drive plate assembly, belt pulley assembly and coil assembly three parts usually.The belt pulley assembly is the transmission part and the magnetic conductive part of clutch, and it, and is connected with the motor car engine driving wheel by belt on the protecgulum of compressor by Bearing Installation, is used for transmission of power with motor to compressor; Coil assembly is the electric control element of clutch, is assemblied in the cavity of belt pulley assembly and an end is fixed on the protecgulum of air condition compressor; The drive plate assembly is connected by key on the main shaft of compressor and near the rubbing surface of belt pulley assembly; A gap is arranged between drive plate assembly and belt pulley assembly.
The working principle of automobile air conditioner electromagnetic clutch is: when opening air-conditioning, the coil assembly energising produces magnetic field, by the electromagnetic force of pivoted pulley assembly generation all the time, the drive plate assembly is attracted to be fitted on the rubbing surface of belt pulley assembly, drive plate assembly and belt pulley assembly after the adhesive rotate synchronously, drive the compressor main shaft rotation by friction torque, thereby drive the air condition compressor running; During the electromagnetic coil outage, electromagnetic force disappears, and the drive plate assembly separates with the belt pulley assembly by resetting means, and compressor quits work, the idle running of belt pulley assembly.
Because the automobile running environment is comparatively abominable usually; and outside each parts of automobile air conditioner electromagnetic clutch all are exposed to; dust, gravel, water, wet goods foreign material enter clutch inside through regular meeting; particularly when entering between drive plate assembly and the belt pulley assembly in the gap, very serious consequence will be caused.If water or oil content enter the friction position of belt pulley assembly and drive plate assembly, can make friction torsion greatly reduce the sensitivity variation of clutch; If a large amount of dusts, grit enter the gap, might cause rubbing position scratch damage or distortion, the working life of having reduced clutch; If dust, grit are crossed as many as and are filled up the gap, will cause automobile air conditioner compressor to rotate with motor car engine, have a strong impact on the proper functioning of clutch, even can cause the production safety accident.
A kind of magnetic clutch proofing dust and protecting cover is disclosed among the Chinese patent literature CN202140475U.This magnetic clutch proofing dust and protecting cover is wiper of rubber, is located on the periphery of magnetic clutch.This model utility effectively utilized that rubber elasticity is good, intensity is high, sealing is strong, wear-resistant, corrosion protection, shock proof specificity, be close to the setting of magnetic clutch periphery, played the effect of dustproof anticorrosive erosion effectively, guaranteed that magnetic clutch can normally use under rugged environment.But because this model utility is wrapped up magnetic clutch integral body with rubber ring, heat disperses when being unfavorable for the automobile air conditioner compressor operation.
The model utility content
The utility model technical issues that need to address provide a kind of dust, water, oil and other foreign material of can preventing and enter the automobile air conditioner electromagnetic clutch in gap between drive plate assembly and the belt pulley assembly.
For solving the problems of the technologies described above, the technological scheme that the utility model adopted is:
The automobile air conditioner electromagnetic clutch of band dust-proof cover, comprise drive plate assembly and belt pulley assembly, described belt pulley assembly comprises by bearing and is arranged on main pulley on the compressor main shaft, the drive plate assembly is connected on the compressor main shaft and the rubbing surface of close belt pulley assembly by key, is provided with the gap between described drive plate assembly and the belt pulley assembly; Described drive plate assembly arranged outside one covers the dust-proof cover in gap between drive plate assembly and drive plate assembly and the belt pulley assembly, and described dust-proof cover is fixedly mounted on the end of main pulley near the drive plate assembly.
Further improvement of the utility model is: described dust-proof cover is a circular cover body.
Further improvement of the utility model is: described dust-proof cover by screw on main pulley.
Further improvement of the utility model is: the quantity of described screw is more than three or three, and screw is that the even cloth in the center of circle is on main pulley with the compressor main shaft.
Further improvement of the utility model is: be provided with rubber sheet gasket between described dust-proof cover and the main pulley.
Further improvement of the utility model is: described dust-proof cover is electrophoresis or zinc-plated steel dust-proof cover, and the thickness of steel dust-proof cover is 1mm ~ 2mm.
Because the technological progress of having adopted technique scheme, the utility model to obtain is:
The utility model has installed a dust-proof cover additional on known automobile air conditioner electromagnetic clutch basis.This dust-proof cover is installed in by screw on the main pulley of belt pulley assembly, and its size matches with belt pulley assembly main pulley.In this dust-proof cover covers the gap between drive plate assembly and drive plate assembly and the belt pulley assembly fully, dust, water, oil and other foreign material that can effectively prevent external environment condition enter this gap, guarantee the cleanliness of inside, gap and two sides, gap.When automobile travels under mal-condition, can guarantee the safety traffic of magnetic clutch proper functioning and automobile, prolong the life-span of magnetic clutch, and do not influence the compressor heat radiation.
Between dust-proof cover and main pulley, be provided with rubber sheet gasket, effectively utilized that rubber elasticity is good, intensity is high, sealing is strong, wear-resistant, corrosion protection, shock proof specificity, fix with screw again, further guaranteed the sealing of dust-proof cover, strengthened the anti-dirt effect of waterproof.
The quantity of used screw is selected for use more than three or three, and is that the center of circle is distributed on the main pulley with the compressor main shaft, can guarantee the steadiness that dust-proof cover is installed, the bolt looseness phenomenon of avoiding automobile might occur when bumpy sections is travelled.
