Description

Technical Field

[0001] This utility model belongs to the field of automotive parts technology, and specifically relates to a stain-resistant automotive ABS gear ring. Background Technology

[0002] The automotive braking system is a specialized device used to apply braking force to the wheels of a vehicle to achieve forced deceleration, stopping, or parking. Among them, the ABS tooth ring is one of the core components of the anti-lock braking system (ABS). It is installed inside the wheel hub and generates wheel speed signals through the rotation of the tooth grooves, which are transmitted to the sensors to help the system accurately control the braking force, prevent wheel lock-up, and improve braking safety.

[0003] For example, Chinese patent literature discloses an anti-lock braking device ABS toothed ring [Application No.: 202023058542.4; Authorization Announcement No.: CN213831654U], which includes an iron ring; a mounting groove is provided around the top of the iron ring, a toothed block is installed in the mounting groove, and a mounting hole is provided in the middle of the toothed block; inserts are integrally formed on both sides of the bottom of the toothed block, slots are provided at both ends of the bottom of the mounting groove, and bolts are inserted into the mounting holes.

[0004] The aforementioned ABS gear ring of the anti-lock braking system is easy to install and remove, and can quickly and efficiently complete the later maintenance work. However, its anti-fouling ability is poor. The tooth grooves inside the aforementioned ABS gear ring are conventionally manufactured, and the self-cleaning effect is not ideal. In harsh environments, the tooth grooves are easily blocked by mud, sand and oil, which leads to inaccurate wheel speed sensor signal acquisition, affects the response of the ABS system, and at the same time cannot enhance the magnetism of the gear ring material, resulting in the inability to improve the sensor signal strength and making it susceptible to electromagnetic interference. Summary of the Invention

[0005] The purpose of this invention is to address the aforementioned problems in the existing technology by providing an anti-fouling automotive ABS gear ring that can reduce the adhesion of impurities such as mud, sand, and oil, ensure signal acquisition stability, enhance material magnetism, and improve sensor signal strength.

[0006] The purpose of this utility model can be achieved through the following technical solution: a dirt-resistant automotive ABS gear ring, including a retainer, a gear ring body installed in the inner cavity of the retainer, teeth fixedly connected to the top of the gear ring body, a ferrite sheet embedded in the top of the teeth, a tooth groove provided between the teeth on both sides, a dirt guide groove provided at the bottom of the inner cavity of the tooth groove, and a V-shaped groove provided at the top of the retainer.

[0007] This anti-fouling automotive ABS gear ring mainly consists of a V-groove, gear ring body, gear groove, ferrite sheet, dirt guide groove, and teeth. Through the V-groove, gear ring body, gear groove, ferrite sheet, dirt guide groove, and teeth, it has anti-fouling function, which can reduce the adhesion of impurities such as mud, sand, and oil, ensure the stability of signal acquisition, enhance the magnetic properties of the material, and improve the sensor signal strength.

[0008] In the aforementioned anti-fouling automotive ABS gear ring, the retainer includes a mounting base plate, the top of which is welded with a mounting outer ring, and mounting holes are provided at the top edge of the mounting base plate. In practical applications, the mounting holes facilitate the insertion of bolts to secure the retainer.

[0009] In the aforementioned anti-fouling automotive ABS gear ring, a mounting guide block is welded to the rear side of the inner cavity of the mounting outer ring, and the number of mounting holes is six. In practical applications, by setting the mounting guide block, the mounting guide groove on the surface of the gear ring body can be aligned with the mounting guide block before insertion, thus ensuring that the dirt guide groove and the opening of the V-groove are aligned.

[0010] In the aforementioned anti-fouling automotive ABS gear ring, a mounting groove is provided at the top of the teeth, and the inner cavity of the mounting groove is fixedly connected to the ferrite sheet using strong adhesive. In practical applications, the mounting groove facilitates the fixed installation of the ferrite sheet.

[0011] In the aforementioned anti-fouling automotive ABS gear ring, there are several toothed grooves and V-grooves, all evenly distributed, and the outer side of the dirt-guiding groove is aligned with the V-groove. In practical applications, the depth of the V-groove is 1.2 mm.

[0012] In the aforementioned anti-fouling automotive ABS gear ring, a mounting guide groove is provided at the bottom of the rear side of the gear ring body. Both the gear groove and the dirt-guiding groove have oleophobic and hydrophobic treatments. In practical applications, the oleophobic and hydrophobic coating is made of PTFE material and is applied to the surface of the gear ring via a spraying process. After curing, the thickness is 20μm, effectively preventing oil stains from adhering to the inner wall of the gear groove, resulting in better dirt removal.

[0013] Compared with existing technologies, the advantages of this anti-fouling automotive ABS gear ring are: it has anti-fouling function during operation, which can reduce the adhesion of impurities such as mud, sand and oil, ensure the stability of signal acquisition, enhance the magnetic properties of the material, and improve the signal strength of the sensor.

[0019] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0020] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this anti-fouling automotive ABS gear ring includes a retainer 1, a gear ring body 3 installed in the inner cavity of the retainer 1, teeth 13 fixedly connected to the top of the gear ring body 3, ferrite sheets 5 embedded in the top of the teeth 13, a tooth groove 4 provided between the teeth 13 on both sides, a dirt guide groove 7 provided at the bottom of the inner cavity of the tooth groove 4, and a V-shaped groove 2 provided at the top of the retainer 1.

[0021] To elaborate further, the cage 1 includes a mounting base plate 10, with a mounting outer ring 11 welded to the top of the mounting base plate 10. Mounting holes 9 are provided at the edge of the top of the mounting base plate 10. Mounting guide blocks 12 are welded to the rear side of the inner cavity of the mounting outer ring 11. There are six mounting holes 9.

[0022] The top of the tooth 13 has a mounting groove 6, and the inner cavity of the mounting groove 6 is fixedly connected to the ferrite sheet 5 with strong adhesive. There are several tooth grooves 4 and V-grooves 2, which are evenly distributed. The outer side of the dirt guide groove 7 is aligned with the V-groove 2. The bottom of the rear side of the tooth ring body 3 has a mounting guide groove 8. The inner cavities of the tooth grooves 4 and dirt guide grooves 7 are treated with oleophobic and hydrophobic coatings.

[0023] In actual manufacturing, a dirt guide groove 7 is provided at the bottom of the inner cavity of the tooth groove 4. The bottom of the dirt guide groove 7 is designed with an inclined bottom, with the inner side of the bottom being the highest point and the outer side of the bottom being the lowest point. At the same time, a mounting guide block 12 is provided on the top of the mounting outer ring 11, so that the opening on the inner side of the mounting guide block 12 is aligned with the opening on the outer side of the dirt guide groove 7. In this way, as the tooth ring body 3 rotates with the wheel, centrifugal force is used to throw out the mud and dirt in the dirt guide groove 7. Since the bottom of the dirt guide groove 7 is designed to be inclined outward, it can accelerate the discharge of dirt and prevent mud and dirt from adhering to the inner wall of the tooth groove 4, thus ensuring the stability of signal acquisition. A ferrite sheet 5 is embedded in the top of the tooth 13. Through its unique magnetic and electrical properties, it can effectively concentrate or enhance the magnetic field, thereby improving the signal strength and effectively suppressing external electromagnetic interference.
