The main parts sizes such as wheel, electromagnetic coil, reseting spring leaf and sucker form.There are two types of basic patterns for electromagnetic clutch：One kind is
Rotating electromagnetic coil type, electromagnetic coil and belt pulley rotate together；Another kind is to determine ring type, and electromagnetic coil maintains static, this
Kind structure is using more.
Existing vehicle-mounted air conditioner compressor determines ring type electromagnetic clutch, and wherein electromagnetic coil is screwed in compressor
Shell on, sucker is connected with screw with compressor shaft, and belt pulley is supported on bearing on compressor shaft, can on axis from
By rotating, reseting spring leaf /V is socketed on compressor shaft, and among the two in belt pulley and sucker.When refrigeration switchs
During connection, electromagnetic coil circuit is connected, and has electric current to flow through, and generates electromagnetic attraction, is inhaled dynamic sucker and is allowed to tightly be bonded with belt pulley,
At this moment reseting spring leaf is become by swaging, and the torque of belt pulley passes to compressor shaft by sucker, and compressor starts is made to work；When
When refrigeration switch is closed, circuitry cuts, the electromagnetic attraction of electromagnetic coil disappears, and sucker is automatic under the reset force effect of spring leaf
It resets, departs from belt pulley, with regard to being stopped naturally, belt pulley only dallies compressor on compressor shaft.It is multiple in said structure
The deformation restoring force of position spring leaf drives sucker to depart from the sole power source of belt pulley as when refrigeration switch is closed, and concentrates
It is higher to accept degree, deformation strain can seriously affect the normal service life of electromagnetic clutch entirety than more serious.Therefore,
It is necessary to make further technological improvement to the electromagnetic clutch in above-mentioned.
The content of the invention
A kind of vehicle-mounted air conditioner compressor is provided the purpose of the present invention is to solve the deficiency of above-mentioned technology determines ring type
Electromagnetic clutch, the sucker of above-mentioned middle electromagnetic clutch are resetted using magnetic force.
In order to achieve the above object, a kind of vehicle-mounted air conditioner compressor designed by the present invention determines ring type electromagnetic clutch,
The T-shaped sucker being socketed in including one by feather key on vehicle-mounted air compressor axis, therefore T-shaped sucker both can be in vehicle air pressure
It slidably reciprocates on contracting arbor, and vehicle-mounted air compressor axis can be driven to rotate, one is socketed in T-shaped sucker by ball bearing
Longitudinal component on belt pulley and an electromagnetic coil, the belt pulley be equipped with annular chamber, the bottom of the annular chamber
Ring is furnished with through hole, and the lateral part of above-mentioned T-shaped sucker is located at the one side of belt pulley and corresponding with through hole, is additionally provided between the two
One preset clearance, electromagnetic coil are located in the annular chamber, and are fixed with the outer shell phase of vehicle-mounted air conditioner compressor, and above-mentioned determines
Ring type electromagnetic clutch further comprises more than one magnetic force nut, and the arrangement of above-mentioned magnetic force nut is screwed in vehicle air compression
The axially outer end of arbor, and it is attracted with the lateral part of T-shaped sucker；When electromagnetic coil energization work, sucker overcomes magnetic force
It fits after the magnetic force of nut with belt pulley.
A kind of vehicle-mounted air conditioner compressor determines ring type electromagnetic clutch provided in above-mentioned, in structure when electromagnetic coil breaks
After electricity is stopped, sucker carries out active homing under the magneticaction of magnetic force nut, and reset stability is good, and rate is high.
As further technological improvement, the lateral part of above-mentioned middle T-shaped sucker is in central elevation shape, because of central elevation
And the cambered surface cavity formed is towards belt pulley.The lateral part of sucker is powered in electromagnetic coil in the further Technological improvement plan
It is attracted with the outer surface of belt pulley under the electromagnetic force generated during work, and in entire attracting process sucker horizontal stroke
Deformation can be generated to part, is conducive to improve its actuation stability with belt pulley between the two, so as to which belt elevator wheel is with inhaling
Transmission efficiency between disk.
Compare the prior art, and a kind of acquired vehicle-mounted air conditioner compressor determines ring type electromagnetic clutch in the present invention,
It is relatively stable, efficient during the open and close of control vehicle-mounted air compressor, while service life is also longer.
