Background technique
Automotive industry is one of pillar industry of China, car air conditioner is as the application of air-conditioning technical on automobile, can create quiet micro circulation environment in the car, the indoor temperature of car steering, moistening degree, clean degree, noise and air velocity etc. are controlled in the critical field, not only help to keep driver and conductor's body ﹠ mind health, increase work efficiency, and running safety is had positive role.
Automobile air conditioner compressor is driven by magnetic clutch by motor car engine, and automobile air conditioner electromagnetic clutch is the device of the transmission of power between motor car engine and the automobile air conditioner compressor.Automobile air conditioner electromagnetic clutch generally all is made up of these three parts of belt pulley assembly, coil assembly and drive plate assembly.The belt pulley assembly, can freely rotate on the skull of compressor by Bearing Installation.The belt pulley assembly transmits the power of motor to compressor.Coil assembly is installed in the corresponding core slots of belt pulley assembly, and the drive plate assembly is installed in by flange plate on the main shaft of compressor, fixedlys connected with the main shaft of compressor.Be provided with the gap between drive plate assembly and the belt pulley assembly, the size in gap should guarantee that magnetic clutch when energising can reliable adhesive in scheduled time, make drive plate assembly and belt pulley assembly applying run-in synchronism, drive plate assembly and belt pulley assembly can normally break away from when guaranteeing the magnetic clutch outage again, can not cause during the idle running of belt pulley assembly that clutch is owing to clutch coil is burnt in the friction heating.
Automobile air conditioner electromagnetic clutch is subjected to controls such as air-conditioning switch, temp controller, A/C amplifier, pressure switch, connects the transmission of power between motor and the compressor when needs use.When not needing to use, cut off the transmission of power between motor and the compressor.The working principle of magnetic clutch is when electric current passes through coil assembly, produces stronger magnetic field, makes drive plate assembly and the adhesive of free pivoted pulley assembly, thus the Driven Compressor main axis rotation; When failure of current, magnetic field just disappears, and by spring action drive plate and belt pulley separately, compressor quits work.
Because the residing circumstance complication of vehicle compressor, and the effect of coil assembly electromagnetic attraction when the state of energising, make dust in air, water, oil and some ferromagnetism impurity accumulate on the adhesive face of magnetic clutch easily, friction torsion is greatly reduced, the sensitivity of clutch also can variation, thereby cause between belt pulley and the drive plate generation of phenomenons such as skidding, clutch burns, influence the vehicle compressor proper functioning.
The model utility content
The utility model technical issues that need to address provide a kind of automobile air conditioner electromagnetic clutch with dust guard, prevent that airborne impurity from entering in the magnetic clutch, guarantee the vehicle compressor reliably working, prolong the working life of car air conditioner.
For solving the problems of the technologies described above, the technological scheme that the utility model adopted is:
Automobile air conditioner electromagnetic clutch with dust guard, comprise the belt pulley assembly that covers at compressor head by Bearing Installation and with the transmission of power of the belt pulley assembly drive plate assembly to compressor main shaft, described drive plate assembly changes clutch state with the belt pulley assembly by being arranged on coil assembly in the belt pulley assembly core slots; The arranged outside of drive plate assembly has and prevents that airborne impurity from entering the dust cover in gap between drive plate assembly, belt pulley assembly and drive plate assembly and the belt pulley assembly, dust cover comprise by fixing bolt be installed on the drive plate assembly end cap and with the vertically disposed annular sidewall of end cap; The belt pulley of described belt pulley assembly is provided with groove near a side of drive plate assembly, and the end of annular sidewall extends in the groove.
Further improvement of the utility model is: be provided with supporting sleeve between the wheel hub of described end cap and drive plate assembly.
Further improvement of the utility model is: the quantity of fixing bolt has three at least.
Because the technological progress of having adopted technique scheme, the utility model to obtain is:
Automobile air conditioner electromagnetic clutch with dust guard can prevent that airborne impurity from entering in the automobile air conditioner electromagnetic clutch, has guaranteed the vehicle compressor reliably working, has prolonged the working life of car air conditioner.
The end of dust cover annular sidewall extends in the pulley groove of belt pulley assembly, on the one hand the gap between drive plate assembly and drive plate assembly and the belt pulley assembly can directly not exposed in air, prevent that dust in air, water, oil and some ferromagnetism accumulation of impurities from causing the damage of clutch on magnetic clutch; Guaranteed that on the other hand belt pulley assembly and dust cover annular sidewall can not wear and tear at work mutually.
The end cap of dust cover is fixed on by supporting sleeve on the wheel hub of drive plate assembly by fixing bolt, and the quantity of bolt has three at least, to guarantee the secure fixation of dust cover.
