Background technique
Automobile air conditioner electromagnetic clutch is a power transmitting deice between motor car engine and automobile air conditioner compressor, and motor car engine drives automobile air conditioner compressor work by magnetic clutch.The magnetic clutch occurring in the market, generally include belt pulley, coil and Suction cup assembly, coil is arranged in belt pulley, Suction cup assembly is arranged at the side of belt pulley and is in transmission connection with compressor main shaft, its working principle is in the time of coil electricity, to produce magnetic force Suction cup assembly is pull-in on the end face of belt pulley, drive Suction cup assembly synchronously to rotate with belt pulley by frictional force, and then drive compressor main shaft synchronously to rotate, make compressor operating.But, above-mentioned magnetic clutch is unreasonable because structure arranges, and has following defect: the first, and the belt pulley end face corresponding with sucker is plane, cause the area of contact of Suction cup assembly and belt pulley less, thereby cause the transmission performance between belt pulley and Suction cup assembly lower; The second, because Suction cup assembly speed when to pulley movements is larger, and Suction cup assembly and belt pulley Contact can produce relative sliding, causes Contact noise larger; The 3rd, between Suction cup assembly and belt pulley, all adopt rigidity to contact, cause contact surface abrasion comparatively serious, frictional force reduces thereupon, causes the generation of skidding, affects the normal work of compressor, and has reduced the working life of clutch entirety.
Model utility content
The purpose of this utility model is for the defect of prior art and deficiency, provide a kind of simple and reasonable, area of contact is large, transmission performance better, be difficult for the novel automobile air-conditioner magnetic clutch that weares and teares, grow working life between less, the sucker of noise and belt pulley.
For achieving the above object, the utility model is by the following technical solutions:
Novel automobile air-conditioner magnetic clutch described in the utility model, comprise belt pulley, coil, sucker and axle sleeve, described belt pulley periphery inner side is provided with annular groove, described coil is positioned at described annular groove, described sucker is located at a side of belt pulley, and between sucker and belt pulley, being gap arranges, described sucker end is provided with the first end face coordinating with belt pulley, described belt pulley is provided with second end face corresponding with first end face, described sucker is provided with spring sheet, described axle sleeve is connected with described spring sheet, the outside of described spring sheet is provided with connecting plate, described axle sleeve and described spring sheet, connecting plate three be connected successively, the periphery of described the first end face is provided with first conical surface, the periphery of described the second end face is provided with second conical surface corresponding with first conical surface, on described the second end face, edge is circumferentially embedded with friction plate A, on described second conical surface, be embedded with friction plate B.
Further, also comprise bonnet, described bonnet covers at outside described sucker and is fixedly mounted on belt pulley.
Further, the angular range between described first conical surface and the first end face is 35～65 degree.
Further, described friction plate A equates with the thickness of friction plate B.
The beneficial effects of the utility model are: by first conical surface being set at the periphery of the first end face, periphery setting second conical surface corresponding with first conical surface of the second end face, in the time of sucker and belt pulley adhesive, first conical surface and the laminating of second conical surface, increase the area of contact between sucker and belt pulley, made the utility model transmission performance better; By edge on the second end face, friction plate A is circumferentially set, on second conical surface, be embedded friction plate B, when sucker and belt pulley Contact, friction plate A and friction plate B have effectively played the effect of buffering, have reduced the noise that Contact produces, and, friction plate A coordinates and has also avoided the rigidity between sucker and belt pulley to contact with friction plate B, reduce the wearing and tearing of surface of contact, made not to be prone to skidding between both surface of contact, extended working life.
