[0002] Pulleys are a type of hub-type parts. With their unique structural characteristics, they are widely used in various types of mechanical equipment, especially in situations where power is transmitted over long distances, such as automobiles, mining machinery, textile machinery, etc. The general outline size of pulleys is relatively large, so the production process is mainly based on casting and forging. Specifically, larger pulleys are usually produced by casting, and the material is mainly cast iron because of its good casting performance; while smaller pulleys tend to be forged, and the material is mostly steel to meet different strength and usage requirements.

[0003] In the existing automotive pulley development process, product design changes frequently, and each product design needs to be customized according to the new parameters provided by the customer, resulting in a wide variety of products. Due to the large variety of products, the mold needs to be frequently replaced and the process parameters need to be adjusted during the production process, which not only increases the difficulty of operation, but also makes it difficult to improve production efficiency. In addition, the pulley system, as an important component of the electronically controlled silicone oil clutch water pump, does not have a modular design. This not only limits the versatility of the product, but also makes the mold cost high. Every time a product is updated or improved, the mold needs to be redesigned, which increases the development cost and cycle. Utility Model Content

[0008] In one embodiment, the connecting block and the silicone oil cavity component are an integrally formed structure.

[0009] In one embodiment, the boss step includes a first plane and a second plane, and a height difference exists between the first plane and the second plane.

[0010] In one embodiment, the valve plate component includes a spring plate, a baffle plate and a valve plate body, and an oil storage cavity is provided at the lower end of the valve plate body.

[0011] In one embodiment, the electromagnetic assembly includes an excitation coil, an iron core and a connector.

[0012] The beneficial effect of the utility model is to provide an electronically controlled silicone oil clutch water pump with an improved pulley component, including a water pump body, a shaft-connected bearing that passes through the water pump body, an electromagnetic assembly installed on one end of the water pump body, a valve plate component connected to the shaft-connected bearing, a pulley and a silicone oil cavity component. The pulley is made by a stamping process, which not only improves the accuracy of the shape and size, but also achieves a lightweight design and reduces material waste.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, an electronically controlled silicone oil clutch water pump with an improved pulley component includes a water pump body, a shaft bearing penetrating the water pump body, an electromagnetic assembly installed on one end of the water pump body, a valve plate component connected to the shaft bearing, a pulley 1 and a silicone oil cavity component 2. The water pump body serves as the supporting base of the entire component. The water pump body can be made of high-strength materials to ensure stable shape and performance during high-speed rotation. The high-strength material can be cast iron or stainless steel.

[0025] The pulley 1 is connected to the silicone oil cavity component 2 by a fixed connection structure. In this embodiment, the pulley 1 is made of steel by a stamping process. Compared with the traditional casting or forging process, the stamping process can more accurately control the shape and size of the material, reduce the unnecessary use of materials, and ensure strength and achieve lightweight design. Specifically, the silicone oil cavity component 2 is provided with a plurality of connecting blocks 21, and the pulley 1 is provided with a corresponding connecting plate 11; the connecting blocks 21 and the connecting plates 11 are respectively provided with a plurality of bolt holes 4 corresponding to each other (the number of bolt holes 4 depends on the actual application situation), and the connecting blocks 21 and the connecting plates 11 are fastened and connected by bolts 41 (the silicone oil cavity component 2 and the pulley 1 are tightly connected together by the pre-tightening force of the bolts 41), and the connecting blocks 21 and the silicone oil cavity component 2 are an integrally formed structure. By adjusting the distribution diameter of the bolt holes 4 of the silicone oil cavity component 2, pulleys 1 of different diameters can be matched (without redesigning and developing the silicone oil cavity component 2), so as to meet the needs of different products. This modular design makes the assembly and disassembly of the components more convenient and quick.

[0026] In practical applications, the silicone oil cavity component 2 is provided with a boss step 5 at the portion abutting against the pulley 1 to achieve positioning and balance adjustment between components. The boss step 5 includes a first plane 31 and a second plane 32, and there is a height difference between the first plane 31 and the second plane 32. It is possible to replace pulleys 1 of different diameters without replacing the silicone oil cavity component 2. The pulley 1 with a large diameter can abut against the first plane 31, and the pulley 1 with a small diameter can abut against the second plane 32, which improves the versatility and flexibility of the components to a certain extent.

[0027] In practical applications, the shaft-connected bearing includes an axis, a first bearing and a second bearing. The first bearing and the second bearing are respectively sleeved on the axis and can rotate freely. The water pump body is tightly sleeved on the bearings to form a stable rotating support structure.

[0028] In actual application, the valve plate component is connected to the shaft bearing, and the valve plate component includes a spring plate, a baffle plate and a valve plate body. The lower end of the valve plate body is provided with an oil storage cavity for storing and adjusting the flow of silicone oil to control the working state of the clutch. The valve plate component makes the clutch respond more quickly and accurately. The valve plate component is designed according to the prior art, so it will not be described in detail in this embodiment, and the detailed structure is not shown in the drawings.

[0029] In actual application, the electromagnetic assembly is installed at one end of the water pump body, including components such as an excitation coil, an iron core and a connector. By controlling the current change of the excitation coil, the silicone oil clutch is electromagnetically driven, thereby adjusting the engagement and disengagement state of the clutch. The electromagnetic assembly is designed according to the prior art, so it will not be described in detail in this embodiment, and the detailed structure is not shown in the drawings.

[0030] The above embodiments are preferred implementation schemes of the present utility model. In addition, the present utility model can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the scope of the present utility model patent.

[0031] In order to make it easier for ordinary technicians in the field to understand the improvements of the present invention over the prior art, some drawings and descriptions of the present invention have been simplified, and for the sake of clarity, some other elements are omitted in this application document. Ordinary technicians in the field should realize that these omitted elements may also constitute the content of the present invention.
