What are the performance requirements of ABS magnetic sealing ring?

1. Wear resistance and corrosion resistance
Wear resistance: ABS magnetic sealing ring needs to withstand the friction and heat generated by the high-speed rotation of the wheel, so its material is required to have excellent wear resistance. Common wear-resistant materials include high-hardness alloys and wear-resistant rubbers, which can withstand frequent friction and are not easy to wear, ensuring the long-term use of the sealing ring.
Corrosion resistance: New energy vehicles may encounter various complex road environments during operation, such as mud, sand and dust, which may cause corrosion to the ABS magnetic sealing ring. Therefore, its material is required to have excellent corrosion resistance, be able to resist the erosion of chemicals such as acid, alkali, and salt, and ensure the stability and reliability of the sealing ring.
2. Magnetism and sealing
Magnetism: ABS magnetic sealing ring needs to have sufficient magnetism so that it can accurately sense the speed and rotation state of the wheel. The strength of magnetism directly affects the performance of the ABS system, so the magnetism of the sealing ring must be stable and reliable.
Sealing: Sealing is another important performance requirement of ABS magnetic sealing ring. It must be able to effectively prevent external dust, moisture and other impurities from entering the braking system to ensure the cleanliness and normal operation of the braking system. At the same time, the sealing ring also needs to have excellent sealing performance to ensure that no leakage or seepage occurs during braking.
3. Temperature adaptability
High temperature stability: During braking, the ABS magnetic sealing ring may be affected by high temperature. Therefore, its material is required to have excellent high temperature stability and be able to maintain stable performance and structure under high temperature environment.
Low temperature adaptability: In the cold winter, the braking system of new energy vehicles also needs to work normally. Therefore, the ABS magnetic sealing ring also needs to have good low temperature adaptability and be able to maintain normal magnetic and sealing performance under low temperature environment.
4. Dimensional accuracy and installation requirements
Dimensional accuracy: The dimensional accuracy of the ABS magnetic sealing ring has an important influence on its performance. It is required that its outer diameter, inner diameter and thickness and other dimensions must be accurate to ensure perfect matching with the braking system.
Installation requirements: When installing the ABS magnetic sealing ring, strict installation requirements must be followed. Including the correct installation position, appropriate preload, etc., to ensure that the sealing ring can perform at its best performance.
