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. 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.
Clutch Friction Disc
1.Remove sharp corners and burrs, and the surface of the friction disc without oil.
2.The friction coefficient of the friction plate is greater than or equal to 0.25 (the abrasive part is a steel part).
3.It has good thermal stability, and the friction coefficient should not be less than 0.25 when the temperature reaches 100°C.
