AI Technical Summary

Technical Problem

Brake discs are prone to rust in open-air environments, especially in rainy and humid conditions, leading to the formation of red and black rust, which affects braking performance and causes vibration problems. Existing protective measures become ineffective after user use.

Method used

Movable blades are designed in the rim, which are controlled to extend or retract via a drive assembly, closing or opening the gap to prevent moisture from entering. Combined with manual and automatic control systems, they can adapt to different usage scenarios.

Benefits of technology

It effectively prevents brake disc rust, reduces vibration, improves driving comfort, and extends the life of related components, making it suitable for long-term parking and common use scenarios.
