The design and the device of a clutch of the compressor of the conditioner of the car

To date, air conditioning is in the rooms and in cars. Both systems have a similar design and operating principle. One of these common parts is the air conditioning compressor clutch. "Nissan", "Renault" and even VAZs, equipped with air conditioning systems, have this element in their design.

As you know, each device that provides air cooling has a special compressor. It is needed to compress the gaseous refrigerant, which provides a cold air flow. No modern compressor can do without a coupling that disconnects it from the drive pulley. How does it work?

Couplings of the compressor of the conditioner are involved constantly, including at switching-off of all system. Remarkably, the earliest copies of these details looked like a solenoid. The latter was interconnected with the drive pulley of the compressor, so the part repeated its movements. Modern devices differ significantly from their ancestors. At this time, all air conditioning compressor clutches are stationary, and can be located just before the mechanism itself.

The principle of operation of this device consists in feeding power to the solenoid, after which a magnetic field is formed in the system, and the disk is pressed against the driving pulley. For this reason, the clutch of the air conditioning compressor is often called electromagnetic. It is also worth noting that the operation of this device takes from the car about 5-10 horsepower of power, which, undoubtedly, is displayed on the dynamics of acceleration and economy. Recently, cars have begun to install air conditioning compressor clutches, which require the use of special types of lubricant. This is due to the special design and more refined operation principle.

How to understand that the car requires replacement of the air conditioning compressor clutch? This mechanism is an important detail in the air conditioning system, so it needs to pay special attention. Among the main features is to highlight the noise of the mechanism when the system is turned on / off. Another important detail is the gap on the electromagnetic clutch. If it is not adjusted correctly, it can lead to slippage or even failure of the pulley. After the pulley, the clutch itself will break.

Another sign of replacing this part is the wear of the slot mechanism. Usually it wears naturally. If this part has become unusable, the air conditioning compressor clutch should be replaced completely. Of course, you can make repairs, but the cost of these works is not much greater than the price of the new part. Therefore, almost no one is repairing this device. After buying a new air conditioning compressor clutch, you will not only save a lot of your time, but you will be sure of its serviceability. It is not uncommon for a repaired part to fail again in a few weeks.
