Description
Technical field
The utility model relates to a kind of magnetic clutch of used for automobile air conditioning.
Background technique
The air-conditioning that uses on the automobile mostly is to be connected with the motor of automobile by clutch and driving belt etc., the kind of automobile air conditioner clutch is a lot, is exactly two kinds of clutches using always as disclosed magnetic clutch among the Chinese patent 02229533.X, 200310108374.7,200620127439.1.Magnetic clutch comprises drive plate, belt pulley, magnetic coil, belt pulley is connected with motor car engine, belt pulley by Bearing Installation on the shell of compressor or on the main shaft of compressor, coil is between the wheel hub of belt pulley and wheel rim in the formed groove, the compressor end that coil is assemblied in belt pulley one side covers, opposite side at belt pulley is provided with drive plate, the main shaft of drive plate and air condition compressor is connected by key, and the resetting-mechanism that drive plate is separated with belt pulley is installed in the outside of drive plate.When opening air-conditioning, the magnetic coil energising forms electromagnet, and drive plate is inhaled to the belt pulley direction and with the belt pulley end face fitted, owing to exist frictional force between drive plate and the belt pulley end face, thus make belt pulley drive drive plate and air condition compressor running.The drive plate of the clutch of all these structures all is rigidity, its drive plate mainly comprises magnetic attracting disk, fixed plate, flange plate, fixed plate links together magnetic attracting disk and flange plate, and magnetic attracting disk, fixed plate, flange plate all are rigid elements, and the connection between them also is a rigidity.Because the drive part of vehicle mostly is the kind of drive that adopts via a belt drives of motor driving wheel at present, in case so air condition compressor overload or damage locking, the clutch that uses will skid or burn bearing at present, belt pulley shuts down, but belt has motor to drive can not shut down, belt and belt pulley produce friction and damage belt like this, thereby influence the power transmission of whole automobile, and vehicle can only be stagnated; The locking fault takes place suddenly during if run at high speed, and the driver is offhand, also security incident might take place, and in fact annual security incident owing to the appearance of this kind reason is all not within minority.
The model utility content
The utility model technical issues that need to address provide a kind of automobile air conditioner electromagnetic clutch, and when serious overload or locking took place for the compressor of air-conditioning, its can be automatically and the power source disengaging, prevents security incident.
For solving the problems of the technologies described above, technical solution adopted in the utility model is:
Possesses the overload automobile air conditioner electromagnetic clutch of fracture protection automatically; comprise belt pulley, the drive plate that is positioned at the belt pulley outside that is connected with the main shaft of air condition compressor, the magnetic coil that is assemblied in belt pulley one side; belt pulley is connected with motor car engine on compressor case and by belt by Bearing Installation, and magnetic coil is connected compressor end and covers.Drive plate comprises magnetic attracting disk, fixed plate, flange plate, magnetic attracting disk is corresponding with magnetic coil circular, flange plate is connected on the main shaft of air condition compressor by key, be connected by fixed plate between flange plate and the magnetic attracting disk, between the magnetic attracting disk of drive plate and fixed plate, the resetting-mechanism that magnetic attracting disk is separated with belt pulley be installed; Being interrupted being provided with penetrating groove on the fixed plate, is connecting tendon between the adjacent groove.
Further improvement of the utility model is: the groove on the described fixed plate is a circular groove, and it is on the concentric circle in the center of circle that the formed connecting tendon of circular groove is positioned at the air condition compressor alignment of shafts.
Further improvement of the utility model is: the width of described connecting tendon is to bear 1 to 2 times of the required width of torsion under the nominal operation state of compressor.
Further improvement of the utility model is: described resetting-mechanism comprise the rubber ring that is arranged at the fixed plate outside and be through at rubber ring and fixed plate in the ladder pin, the big round platform of ladder pin cooperates with the rubber ring end face, the middle part circle of ladder pin cooperates with the interporal lacuna of rubber ring, fixed plate, and the ladder pin is fixedlyed connected with magnetic attracting disk.Rubber ring, fixed plate are connected on the magnetic attracting disk by the ladder pin.
Owing to adopted technique scheme, the utility model to obtain following technological progress:
The utility model is changed into the connecting tendon structure that can rupture with original fixed plate of consolidating rigid construction forever, connecting tendon fracture automatically on the fixed plate when overload of compressor or locking.When compressor breaks down and transships; moment of torsion increases; when moment of torsion increases to certain degree; act on the fixed plate torsion greater than the connecting tendon of fixed plate can bear strength the time; connecting tendon will rupture; therefore at cltuch slipping, burn bearing before; belt pulley breaks away from the air-conditioning main shaft; air-conditioning does not rerun; thereby avoid the bearing of belt pulley to burn; the protection dynamo belt can remain in operation, and vehicle safe driving has thoroughly been avoided this vehicle contingent security incident when high speed to maintenace point.
It is the connecting tendon of circular groove to form in the center of circle that fixed plate produces with the drive plate center, not only easy to process, but also can calculate the size of circular groove diameter and the width of connecting tendon according to the air condition compressor of different size easily.The width of connecting tendon is when bearing 1 to 2 times of the required width of torsion under the nominal operation state of compressor; both can guarantee that connecting tendon can not rupture under the situation of compressor proper functioning; also can guarantee compressor overload takes place and influence the work of belt, when belt is broken down; connecting tendon ruptures; thereby cut off being connected of air condition compressor and motor, the safety of protection belt and the normal operation of whole power system.
The resetting-mechanism of magnetic attracting disk adopts rubber ring and passes rubber ring and the mode of structure of the ladder pin of fixed plate, has prolonged the working life of resetting-mechanism, and the Shi Buhui that resets produces noise.
