Description

Technical Field

[0001] The utility model relates to an electromagnetic clutch, in particular to a clutch hub for an automobile air conditioner. Background Art

[0002] Electromagnetic clutch is also called electromagnetic coupling. It is an electromagnetic mechanical connector that uses the principle of electromagnetic induction and the friction between the inner and outer friction plates to enable the two rotating parts in the mechanical transmission system to be connected or separated from the driven part without stopping the active part. It is an automatically executed electrical appliance. The automobile electromagnetic clutch is mainly composed of a pulley, a drive assembly, and a wire assembly, in which the drive assembly is fixed to the main shaft of the air-conditioning compressor through a hub spline connection.

[0003] In the prior art, the main shaft is inserted into the wheel hub from one side and fixed in the end of the main shaft by bolt thread connection on the other side. In actual use, the main shaft may become loose due to the rapid rotation of the pulley and the resulting vibration, resulting in a certain deviation in the axial position. Utility Model Content

[0004] The utility model aims to provide a clutch hub for an automobile air conditioner.

[0005] The above technical purpose of the utility model is achieved through the following technical scheme: an automobile air-conditioning clutch hub, including a suction cup, a wheel body is penetrated by the suction cup, a spring sheet is arranged between the suction cup and the wheel body, a rivet connected to the spring sheet is penetrated by the surface of the wheel body, a through hole is arranged at the center position of the wheel body, a fixing ring sheet is arranged at the opening of the through hole on the wheel body, a plurality of grooves are arranged on the inner wall of the fixing ring sheet, a bolt is arranged for inserting the fixing ring sheet, a side groove corresponding to the groove is arranged on the side wall of the bolt, and a penetration rod is arranged between the side groove and the groove.

[0006] It is further configured as follows: the penetration rod includes telescopic sections which are sleeved with each other, and a compression spring is arranged between the telescopic sections.

[0007] It is further configured as follows: a same annular ring is provided on a plurality of the penetration rods.

[0008] It is further configured that: friction lines are provided on the outer wall of the annular ring.

[0009] In summary, the utility model has the following beneficial effects: through the wheel hub, the relative stability between the bolt and the fixing ring can be maintained during use, the problem of the bolt loosening caused by relative rotation between the two is avoided, and the stability of the axial position is ensured.

[0012] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0013] The automobile air-conditioning clutch hub comprises a suction cup 1, a circular hole is provided in the middle of the suction cup 1, a wheel body 2 is penetrated in the circular hole, a spring sheet is provided between the suction cup 1 and the wheel body 2, and a rivet 3 connected to the spring sheet is penetrated on the surface of the wheel body 2.

[0014] A through hole 4 is provided at the center of the wheel body 2, a fixed ring piece 5 is provided at the opening of the through hole 4 on the wheel body 2, three slots 6 are provided on the inner wall of the fixed ring piece 5, and bolts 7 are inserted in the fixed ring piece 5.

[0015] When the bolt 7 is screwed into the fixed ring piece 5, it is connected to the inner wall of the fixed ring piece 5, and the end of the bolt 7 is threadedly connected to the main shaft. An annular ring 12 is provided between the bolt 7 and the fixed ring piece 5, and three penetration rods 9 are provided on the annular ring 12. The penetration rods 9 can be extended. The penetration rods 9 are composed of two sections of telescopic rods that are sleeved together. The opposite ends of the telescopic rods are hollow, and a compression spring 11 is provided in the hollow position. Three side grooves 8 corresponding to the card slots 6 are provided on the thread of the side wall of the bolt 7.

[0016] When installing, first put the annular ring 12 on the bolt 7. When the bolt 7 is close to the fixed ring plate 5 and the main shaft, the side groove 8 on the bolt 7 and the clamping groove 6 on the fixed ring plate 5 are aligned, and then the penetrating rod 9 on the annular ring 12 pops out under the action of the compression spring 11 and enters the circular hole formed between the side groove 8 and the clamping groove 6. In this way, the connection stability between the bolt 7 and the fixed ring plate can be guaranteed, and the problem of the bolt 7 being easy to loosen after a certain period of use can be reduced. Preferably, an annular block is provided between the bolt 7 and the fixed ring plate 5, so that the bolt 7 can be abutted against the annular block when tightened, and the inner diameter of the annular block is larger than the outer diameter of the annular ring 12, thereby ensuring the use of the annular ring 12.

[0017] Friction lines 13 are provided on the outer wall of the annular ring 12 . When the annular ring 12 tilts, it is not easy to insert the penetration rod 9 between the side groove 8 and the clamping groove 6 . The friction lines 13 can facilitate external adjustment of the annular ring 12 .

[0018] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
