Abstract
The utility model relates to an electromagnetic clutch, comprising a main shaft of a compressor, a wheel hub arranged on the main shaft of the compressor, a belt pulley arranged on a front cover of the compressor, an electromagnetic coil arranged on the inner side of the belt pulley, a sucking disk connected with the wheel hub and a spring piece arranged on the sucking disk. The outer margin of the belt pulley is extended toward the outside in the horizontal direction, the extending part is provided with a belt, and a circle of grooves are formed in the center of the belt pulley. The sucking disk is inserted in the grooves on the belt pulley to make a pair of sucking surfaces of the sucking disk and the belt pulley be on a hidden position. The work efficiency and the service life are increased by the utility model.
Description
The utility model relates to the refrigeration compressor in the automotive air-conditioning system, particularly a kind of magnetic clutch that is used for refrigeration compressor.
Existing magnetic clutch kind is a lot, because compressor mounting point on automobile has nothing in common with each other, residing environment is variant greatly, have above engine compartment, environment is cleaner; Have below engine compartment, near ground, attacked by dust, silt, cause magnetic clutch adhesive face foreign matter to be mingled with easily, thereby cause magnetic clutch adhesive moment of torsion to reduce and skid, have a strong impact on the working efficiency and the working life of magnetic clutch.
The purpose of this utility model provides a kind of improved magnetic clutch, and its adhesive face is in more hidden position, has improved the working efficiency and the working life of magnetic clutch.
A kind of magnetic clutch described in the utility model comprises compressor main shaft, be installed in the wheel hub on the compressor main shaft, the belt pulley of installing on the compressor protecgulum is at the electromagnetic coil of belt pulley wheel installed inside, the sucker that is connected with wheel hub, and the spring sheet of on sucker, installing; The outer rim of described belt pulley is extended to the side substantially horizontal, on its extension belt is installed, and is formed centrally a circle groove in belt pulley; Described sucker is flush-mounted in the circle groove of belt pulley, makes a pair of adhesive face of sucker and belt pulley be in more hidden position.
The utility model is installed on the automobile air conditioner compressor, has improved working life, has improved the reliability of air condition compressor and even automotive air-conditioning system simultaneously.
Below in conjunction with accompanying drawing the utility model is elaborated.
Accompanying drawing is a kind of structural representation of magnetic clutch.
Referring to accompanying drawing, a kind of magnetic clutch comprises compressor main shaft 1, is installed in the wheel hub 2 on the compressor main shaft 1, the belt pulley of on the compressor protecgulum, installing 3, at the electromagnetic coil 4 of belt pulley 3 installed inside, the sucker 5 that is connected with wheel hub 2, and the spring sheet of on sucker 5, installing 6.
The outer rim of belt pulley 3 level side is laterally installed belt with extending on its extension 7, and is formed centrally a circle groove 8 in belt pulley 3.
Sucker 5 is flush-mounted in the circle groove 8 of belt pulley 3, makes between a pair of adhesive face 51,31 of sucker 5 and belt pulley 3 to be in more hidden position, goes back setting-in wheel hub 2, spring sheet 6, header board 9 and shock absorbing rubber 10 in the pulley groove 8.
Belt pulley of the present utility model 3 is driven by belt by motor, and sucker 5 is connected with compressor main shaft 1 with wheel hub 2 by spring sheet 6.Between belt pulley adhesive face 31 and the sucker adhesive face 51 gap is arranged, when electromagnetic coil 4 energising, produces magnetic, the elasticity that overcomes spring sheet 6 with sucker 5 adhesives to belt pulley 3.31 and 51 two sides are pulled together, and motor drives compressor operating by the belt pulley 3 and the sucker 5 of adhesive.When electromagnetic coil 4 outage, magnetic disappears, and the elasticity of sucker 5 by spring sheet 6 makes adhesive face 31 and opened in 51 minutes, and compressor just quits work.
