Abstract
The utility model provides an adjustable air gap vehicle air conditioner electromagnetic clutch comprises belt pulley, driving -disc, compression spindle, bearing, compressor shell, coil and iron core. The internal -combustion engine drives the belt pulley and rotates, when not needing air conditioner work, the solenoid cold, do not have magnetic force between belt pulley and the driving -disc, the compressor is out of work. When the needs air conditioner is worked, the solenoid circular telegram, the magnetic line of force that solenoid produced passes through the magnetically gear of belt pulley on and, driving -disc magnetically gear and the iron core on and constitutes closed -loop, and form mutual appeal between belt pulley magnetically gear and driving -disc magnetically gear, this appeal makes the driving -disc rotate along with the belt pulley, drive compressors work.
Description
Technical field
This utility model relates to a kind of automobile air conditioner electromagnetic clutch.
Background technology
Existing automobile air conditioner electromagnetic clutch is mainly made up of belt pulley, drive assembly, coil and iron core. One end of belt pulley and drive assembly is rubbing surface, and coil is arranged on belt pulley inner chamber; Drive assembly is arranged on compressor shaft by spline, and near belt pulley rubbing surface, rotates by the frictional force drives compressor between belt pulley and drive assembly rubbing surface. Due to the abrasion of friction plate, this clutch operationally causes that transmission capacity declines, functional reliability and life-span are relatively low.
Utility model content
The purpose of this utility model is to provide a kind of by magnetic force transmission power, and the automobile air conditioner electromagnetic clutch of conveniently adjusted air gap, and this clutch is mainly made up of belt pulley, driving dish, coil and iron core. One end of belt pulley and driving dish is shaped with magnetic teeth, after coil electricity, makes belt pulley and driving dish combine by the magnetic force between belt pulley, driving dish magnetic teeth, it is achieved driving dish is with belt pulley synchronous axial system; Thus driving compressor to rotate. Compared with ordinary electromagnetic clutch, operationally without friction between belt pulley and driving dish, reliability is higher.
Structure of the present utility model is mainly made up of belt pulley, driving dish, compressor shaft, bearing, compressor case, coil and iron core. Belt pulley therein is made up of wheel hub, spoke and wheel rim, forms annular space between wheel hub and wheel rim; Belt pulley end face is shaped with three circle belt pulley magnetic teeth; Spoke between adjacent magnetic teeth respectively has the belt pulley magnet isolation tank that a circle is discontinuous, play separated magnetic effect. Driving dish is disc, makes with permeability magnetic material, is contained on compressor shaft by spline; It is shaped with two circle driving dish magnetic teeth, between two circle magnetic teeth, has the driving dish magnet isolation tank that a circle is discontinuous, play separated magnetic effect; Driving dish magnetic teeth strides across belt pulley magnetic teeth adjacent on belt pulley respectively, forms two to air gap. Compressor shaft makes stairstepping, driving dish shaft part is cased with elastic ring installing and adjusts pad, elastic ring is used for making driving dish be in right position, driving dish and pulley contact when preventing clutch from not working, keep suitable gap between driving dish and belt pulley when adjusting pad for making clutch work. Coil and iron core are placed in belt pulley annular space, and have certain interval between belt pulley; And be fixed on compressor case by coil brace.
Operation principle: internal-combustion engine drives pulley rotation;When not needing air-conditioning work, solenoid no power; Without magnetic force between belt pulley and driving dish, compressor does not work. When needs air-conditioning work, solenoid is energized; The magnetic line of force that solenoid produces constitutes closed-loop path by belt pulley and belt pulley magnetic teeth thereon, driving dish and driving dish magnetic teeth thereon and iron core. And forming mutual captivation between the magnetic teeth on belt pulley end face and the magnetic teeth on driving dish, captivation drives driving dish with pulley rotation, drives compressor operating.
Accompanying drawing illustrates: accompanying drawing is structural map of the present utility model, and in figure, (1) solenoid, (2) coil brace, (3) bearing, (4) compressor shaft, (5) compressor case, (6) iron core, (7) belt pulley, (8) belt pulley magnetic teeth, (9) belt pulley magnet isolation tank, (10) driving dish, (11) elastic ring, (12) nut, (13) adjust pad, (14) snap ring, (15) driving dish magnet isolation tank, (16) driving dish magnetic teeth.
Detailed description of the invention
In accompanying drawing, driving dish (10) is loaded on compressor shaft (4) by spline, and belt pulley (7) is loaded on compressor case (5) by bearing (3); Solenoid (1) is loaded on compressor case (5) by electromagnetic loop bracket (2).
Claims (2)
1. an adjustable air gap automobile air conditioner electromagnetic clutch, is characterized in that: adjustable air gap automobile air conditioner electromagnetic clutch is made up of belt pulley, driving dish, compressor shaft, bearing, compressor case, coil and iron core; Driving dish therein is disc, makes with permeability magnetic material, is contained on compressor shaft by spline; It is shaped with two circle driving dish magnetic teeth, between two circle magnetic teeth, has the driving dish magnet isolation tank that a circle is discontinuous, play separated magnetic effect; Driving dish magnetic teeth strides across belt pulley magnetic teeth adjacent on belt pulley respectively, forms two to air gap.
2. adjustable air gap automobile air conditioner electromagnetic clutch as claimed in claim 1, is characterized in that: compressor shaft makes stairstepping, is cased with elastic ring installing and adjusts pad on driving dish shaft part; Elastic ring is used for making driving dish be in right position, it is prevented that driving dish and pulley contact when clutch does not work, and keeps suitable gap when adjusting pad for making clutch work between driving dish and belt pulley.
