Tarcza cierna SA8080-111


The friction lining of the electromagnetic clutch of the automobile air conditioner compressor is an important part of the electromagnetic clutch of the automobile air conditioner, and its main function is to transmit torque.


Product Features
The working principle is that when the car air conditioner switch is turned on, the current passes through the electromagnetic coil of the electromagnetic clutch, and the electromagnetic coil generates electromagnetic suction, which makes the driving disc of the compressor combine with the pulley, and transmits the torque of the engine to the compressor shaft to make the compressor shaft rotate. When the air conditioner switch is turned off, the suction force of the electromagnetic coil disappears, and under the action of the spring plate, the drive disc and the pulley are disengaged, and the compressor stops working.
