Problems solved by technology

[0002] Traditional automotive water pumps and air pumps do not have clutches. Even if the water pressure and air pressure of the car meet the working requirements, the water pump and air pump will continue to work, resulting in an increase in the load on the car engine, increasing fuel consumption and emissions, which is not conducive to the energy saving and emission reduction of the car. and environmental protection
[0003] In order to reduce the load on the automobile engine, some automobile water pumps use traditional electromagnetic clutch iron core parts to attract or separate friction plates to realize the clutch between the water pump shaft and the engine output shaft, but this method requires a large axial force, so the electromagnetic The current required by the coil is also relatively large, which virtually increases the energy consumption of the car

Embodiment 1

[0021] Such as figure 1 As shown, the electromagnetic one-way clutch of the present invention includes a main shaft 10, a pulley 20, a wrapping spring fixing ring 40, a wrapping spring 55, a suction disc 43, an elastic reset device and an iron core part 81. Body 80, housing 80 can be the pump housing of water pump or air pump, and iron core part 81 is fixedly installed on the housing, and iron core part 81 is prior art, promptly discloses iron core part as in patent document CN202883084U. In this embodiment, the iron core part 81 is ring-shaped, and is fixedly fitted on the housing 80 , and a coil 84 is wound therein, and the iron core part 81 is arranged coaxially with the main shaft 10 . The pulley 20 is rotatably fitted on the right end of the main shaft 10 through a bearing 25 , and the pulley 20 and the main shaft 10 are arranged coaxially. In this embodiment, the pulley 20 is composed of a left part 26 and a right part 28 , and the outer diameter of the right part 28 is...

Embodiment 2

[0039] Such as image 3 As shown, the difference between this embodiment and Embodiment 1 is that the pulley 20 in this embodiment includes a pulley body 24 and a bearing sleeve 23, the pulley body 24 is fixed on the bearing sleeve 23, and the outside of the right end of the bearing sleeve 23 in this embodiment An annular flange 21 is fixedly arranged on the circumferential surface, and the pulley body 24 is fixedly connected to the annular flange 21 on the bearing sleeve 23 by bolts. In this embodiment, the friction plate is ring-shaped, and the right end surface of the friction plate 45 is opposite to the left end surface of the annular flange 21 , and the part of the annular flange 21 opposite to the friction plate 45 is treated with wear resistance. Of course, the friction plate can also be opposite to the left end surface of the pulley, and the annular flange is located on the radial inner side of the friction plate. The bearing sleeve 23 is rotatably installed on the ma...

Embodiment 3

[0041] Such as Figure 4 , Figure 6 As shown, the difference between this embodiment and Embodiment 2 is that the wrapping spring body 59 of the wrapping spring 55 in this embodiment includes an interconnected holding part 61 and a compression part 63, and the elastic reset device in this embodiment is a wrapping spring body The compression part 63 of 59, that is to say, replaces the spring in embodiment 2 with a compression part. The compression part 63 is also formed by winding spring wires, but there is a larger distance between adjacent spring wires to provide elastic force. combine Figure 5 As shown, a second inner ring 47 is fixedly installed in the suction disc 43, and a mounting groove 48 is opened on the second inner ring 47, and the second pin 65 of the wrap spring 55 snaps into the mounting groove 48 to realize circumferential fixing. , the installation method of the first pin 57 of the wrap spring 55 is the same as in Embodiment 2, and is stuck in the slot 68 o...

Abstract

The invention relates to an electromagnetic one-way clutch for automotive water pumps and air pumps, and a water pump. The electromagnetic one-way clutch comprises a pulley, a spindle rotatably mounted on a housing, a clamp spring fixing ring, a clamp spring, a pull-in disc, an elastic reset device, and a core part fixed on the housing. The pulley is rotatably mounted on the spindle in a sleeving manner. The spindle and the pulley are coaxial. The clamp spring fixing ring is fixedly mounted on the spindle in a sleeving manner. The end face of the clamp spring fixing ring is provided with a circular clamp spring mounting groove. One end of the pull-in disc and one end of the clamp spring are both inserted into the clamp spring mounting groove. The other end of the pull-in disc and the other end of the clamp spring are both mounted on the pulley in a sleeving manner. Pins at one end, inserted into the clamp spring mounting groove, of the clamp spring are peripherally fixed to the clamp spring mounting groove; pins at the other end of the clamp spring are peripherally fixed to the pull-in disc; a friction plate is fixed on the pull-in disc; the elastic reset device can drive the pull-in disc to move to the pulley; the core part can drive the pull-in disc to leave the pulley.
