Description

Technical Field

[0001] This utility model relates to the field of filter technology, specifically to an annular filter for a high-speed solenoid valve in a braking system. Background Technology

[0002] In existing technologies, solenoid valves in braking systems require extremely high precision in fluid control. However, traditional filter structures often suffer from unstable filtration performance, clogging, and insufficient structural strength when dealing with high-speed fluid impacts. Especially under conditions of frequent opening and closing of high-speed solenoid valves, ordinary filters struggle to meet the demands of long-term stable operation, easily leading to performance degradation or even malfunction of the braking system. Summary of the Invention

[0003] In view of this, the present invention provides an annular filter for a high-speed solenoid valve in a braking system.

[0004] To achieve the above objectives, this utility model provides the following technical solution: An annular filter for a high-speed solenoid valve in a braking system includes a filter body on which a solenoid valve is fixedly mounted. The filter body has two coaxially arranged annular support portions and a plurality of reinforcing ribs evenly spaced between the two annular support portions. Each reinforcing rib has its two ends connected to the corresponding annular support portion. The reinforcing ribs are integrally formed with the two annular support portions, and a filter screen structure is provided between adjacent reinforcing ribs.

[0005] Preferably, the two annular support portions include an upper annular support portion and a lower annular support portion, and an upper connecting hole and a lower connecting hole are respectively provided on the upper annular support portion and the lower annular support portion. One end of the solenoid valve passes through the upper connecting hole and the lower connecting hole in sequence and is connected to the filter.

[0006] Preferably, the solenoid valve is interference-fitted with both the upper ring support and the lower ring support.

[0007] Preferably, a plurality of support columns are provided on the end face of the lower ring support portion away from the upper ring support portion. The support columns are conical in shape, and the diameter of the support columns gradually decreases from the side of the support column closer to the lower ring support portion to the side away from the lower ring support portion.

[0008] Preferably, the filter body is made of A3W material.

[0009] Preferably, the filter screen has a plurality of sieve holes, the size of which is set to 300 mesh.

[0010] Preferably, four reinforcing ribs are provided, and the filter structure, the reinforcing ribs, and the filter body are integrally formed.

[0011] The beneficial effects of this invention are as follows: By configuring the filter body as a cylindrical structure with two coaxially arranged annular support parts and equally spaced reinforcing ribs between them, the cylindrical filter structure wraps around the outside of the solenoid valve's oil inlet end while maintaining a gap. The liquid flows radially through the filter to the solenoid valve inlet end, greatly increasing the liquid filtration flow rate and significantly reducing the impact of common filter screen clogging on product performance. The one-piece molding structure makes the filter stronger overall, less prone to deformation and damage under the impact of high-speed flowing liquid, ensuring the filter's stability and reliability. Moreover, this one-piece molding process simplifies the production process, reduces production costs, and improves production efficiency. Attached Figure Description

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] The present invention will now be further described with reference to the accompanying drawings.

[0016] This utility model provides the following technical solution: As attached Figure 1-2As shown, this utility model discloses an annular filter for a high-speed solenoid valve 2 in a braking system, including a filter body 1. A solenoid valve 2 is fixedly mounted through the filter body 1. The filter body 1 has two coaxially arranged annular support portions 3 and several reinforcing ribs 4 evenly spaced between the two annular support portions 3. Each reinforcing rib 4 has its two ends connected to the corresponding annular support portion 3. The reinforcing rib 4 and the two annular support portions 3 are integrally formed. A filter screen structure is arranged between adjacent reinforcing ribs 4. Specifically, in this design, by setting the filter body 1 as a cylindrical structure with two coaxially arranged annular support portions 3 and equally spaced reinforcing ribs 4, the cylindrical filter structure wraps around the oil inlet end of the solenoid valve 2 while maintaining a gap. The liquid passes through the filter radially to the inlet end of the solenoid valve 2, greatly increasing the liquid filtration flow rate and significantly reducing the impact of common clogging of the filter screen structure 5 on product performance. The integrally formed structure makes the filter stronger overall, less prone to deformation and damage under the impact of high-speed flowing liquid, ensuring the stability and reliability of the filter. Moreover, this integral forming process simplifies the production process, reduces production costs, and improves production efficiency.

[0017] Furthermore, the two annular support portions 3 include an upper annular support portion 7 and a lower annular support portion 8. The upper annular support portion 7 and the lower annular support portion 8 are respectively provided with coaxially arranged upper connecting holes 9 and lower connecting holes 10. One end of the solenoid valve 2 passes through the upper connecting hole 9 and the lower connecting hole 10 in sequence to connect to the filter. Specifically, in this embodiment, the upper annular support portion 7 and the lower annular support portion 8 provide a stable and precise installation position for the solenoid valve 2 by providing coaxial upper connecting holes 9 and lower connecting holes 10. The solenoid valve 2 passes through these two connecting holes in sequence, achieving a tight connection with the filter. This ensures that the relative position between the solenoid valve 2 and the filter remains fixed during the operation of the braking system, effectively avoiding loosening or leakage problems caused by vibration or displacement. This design not only enhances the overall stability of the structure but also improves the operational reliability and safety of the braking system.

[0018] Furthermore, the solenoid valve 2 is interference-fitted with both the upper ring support 7 and the lower ring support 8. Specifically, in this embodiment, the interference fit between the solenoid valve 2 and the upper ring support 7 and the lower ring support 8 ensures a tighter and more secure connection between the solenoid valve 2 and the filter. The interference fit, through the slight dimensional difference between the solenoid valve 2 and the connecting hole, generates a certain clamping force during assembly, effectively preventing the solenoid valve 2 from loosening or shifting due to vibration or external forces during operation. This fit not only improves the reliability of the connection but also reduces the potential filter failure caused by loose connections, further ensuring the normal operation and safety of the braking system. Moreover, the interference fit prevents liquid from passing through both sides of the upper ring support 7 and the lower ring support 8, providing a good sealing effect. In this way, the liquid can only enter the solenoid valve 2 along a predetermined path, i.e., after being filtered through the filter structure 5, avoiding the situation where liquid enters the solenoid valve 2 directly without being filtered by the filter structure 5, ensuring the cleanliness of the liquid entering the solenoid valve 2, thereby improving the overall performance and service life of the braking system.

[0019] Furthermore, a plurality of support columns 11 are provided on the end face of the lower ring support portion 8 away from the upper ring support portion 7. The support columns 11 are conical in shape, and their diameters gradually decrease from the side closest to the lower ring support portion 8 towards the side furthest away. Specifically, in this embodiment, the plurality of conical support columns 11 provided on the end face of the lower ring support portion 8 away from the upper ring support portion 7 have diameters that gradually decrease from the side closest to the lower ring support portion 8 towards the side furthest away. This design allows the support columns 11 to form a more stable support point when in contact with the mounting surface, effectively dispersing the pressure generated by the filter and solenoid valve 2 during operation, and reducing deformation or damage caused by excessive local stress. Simultaneously, the conical support column structure 11 facilitates fine-tuning during installation, ensuring the stability and accuracy of the filter installation.

[0020] Furthermore, the filter body 1 is made of A3W material. Specifically, in this embodiment, A3W material is chosen as the filter body 1 primarily because of its excellent mechanical properties and corrosion resistance. A3W material not only has high strength and good toughness, maintaining structural stability under high-speed liquid impact and being less prone to deformation or damage, but also possesses excellent corrosion resistance, resisting the erosion of various chemicals that may be present in the liquid, thereby extending the filter's service life. In addition, A3W material is easy to process and mold, meeting the design requirements of the complex structure of the filter body 1, further improving production efficiency and product quality.

[0021] Furthermore, the filter structure 5 has several sieve holes, the size of which is set to 300 mesh. Specifically, in this embodiment, the sieve holes on the filter structure 5 are set to 300 mesh, a design carefully considered. The 300-mesh sieve holes can effectively intercept impurity particles in the liquid, ensuring that the liquid entering the solenoid valve 2 meets a high cleanliness standard. This avoids the situation where excessively large sieve holes would allow too many impurities to pass through, affecting the performance of the braking system; nor would it cause excessive resistance to liquid flow due to excessively small sieve holes, affecting the filtration flow rate and the normal operation of the braking system. This precise sieve hole setting ensures filtration effectiveness while maintaining smooth liquid flow, providing a stable and reliable liquid supply to the braking system, further improving the overall performance and reliability of the braking system.

[0022] Furthermore, four reinforcing ribs are provided, and the filter structure, reinforcing ribs, and filter body are integrally formed. Specifically, in this embodiment, the four reinforcing ribs not only provide a stable support frame for the filter structure, ensuring that the filter is not easily deformed or damaged under high-speed fluid impact, but also, through an integral forming process with the filter structure and filter body, further enhance the structural strength and stability of the entire filter. This integral forming design eliminates the connection gaps and weaknesses that may exist in traditional assembly methods, effectively preventing connection loosening or structural failure caused by long-term use or high-speed fluid impact. At the same time, the integral forming process also simplifies the production process, improves production efficiency, and reduces production costs.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
