Abstract
Claims
1. An anti-clogging clutch for an automotive air conditioner, characterized by: It includes an electromagnetic coil (1), a pulley (2) and a clutch disc (5), wherein: the pulley (2) is coaxially rotated and sleeved outside the electromagnetic coil (1), the clutch disc (5) is fixedly installed on the outside of the pulley (2) by a nut (13), and a dustproof structure is detachably installed between the pulley (2) and the clutch disc (5); The dustproof structure is coaxially covered outside the clutch disc (5). One end of the dustproof structure is fixedly connected to the outside of the clutch disc (5) by a nut (13), and the other end of the dustproof structure is fixedly connected to the side of the pulley (2) near the clutch disc (5). The dustproof structure can rotate independently with the pulley (2).
2. A non-clogging automotive air conditioner clutch as claimed in claim 1 wherein: The clutch disc (5) has a coaxial cavity (6) on its outer side, and the dustproof structure is fixedly connected to the cavity (6) by a nut (13).
3. A non-clogging automotive air conditioner clutch as defined in claim 2 wherein: The pulley (2) is coaxially fixed with an external threaded connecting plate (3) on the side near the clutch disc (5), and the pulley (2) is threadedly connected to the dustproof structure through the external threaded connecting plate (3).
4. A non-clogging automotive air conditioner clutch as defined in claim 3 wherein: The surface of the external threaded connecting disc (3) is uniformly provided with several heat dissipation holes (4).
5. A non-clogging automotive air conditioner clutch as claimed in claim 3 wherein: The dustproof structure includes a cover plate (7), a bearing (8), a filter cylinder (9), an internal threaded ring (10), and a through hole (11). One end of the filter cylinder (9) is coaxially fixedly connected to the outside of the cover plate (7) through the bearing (8), and the other end of the filter cylinder (9) is coaxially fixedly connected to the internal threaded ring (10). The internal threaded ring (10) is threadedly connected to the external threaded connecting disc (3). The cover plate (7), the filter cylinder (9), and the internal threaded ring (10) are sleeved on the outside of the clutch disc (5) and the external threaded connecting disc (3). A through hole (11) is provided through the center of the surface of the cover plate (7), and the nut (13) is installed in the through hole (11).
6. A non-clogging automotive air conditioner clutch as claimed in claim 5 wherein: A pressure ring (12) is fixedly installed on the inner side of the cover plate (7).
