[0002] In the automobile air conditioning system, the clutch housing of the compressor is a key component, which plays a role in connecting and cutting off the power transmission between the engine and the compressor. Usually, when the engine is working, the power is transmitted to the compressor through the clutch housing, so that the compressor works, thereby producing cold air or warm air. When air conditioning is not needed, the power transmission can be cut off to save fuel and protect the engine. This design not only improves the comfort of the vehicle, but also optimizes the fuel efficiency.
