AI Technical Summary

Technical Problem

In traditional automotive wheel hub structures, bolted connections are susceptible to corrosion from impurities, and sealing structures are prone to failure, leading to safety hazards and shortened service life.

Method used

The design employs a magnetic attraction between magnetic blocks and magnetic rings, along with an airbag sealing design. By utilizing the high magnetic induction intensity of neodymium iron boron permanent magnet materials and the self-adaptability of the airbag, dynamic sealing is achieved, preventing impurities from entering the positioning holes and avoiding bolt corrosion and loosening of the sealing structure.

Benefits of technology

It effectively blocks dust, rainwater and other impurities, improves the reliability of bolted connections and the environmental adaptability of the sealing structure, and ensures long-term reliability and service life.

Abstract

This utility model discloses an automotive wheel hub structure, including a wheel hub body. A central positioning block is provided at the center of the wheel hub body, and spokes are arranged on the outer circumference of the central positioning block. The other end of each spoke is fixedly connected to the inner wall of the wheel hub body. A positioning hole is opened on the outer circumference of the central positioning block, and a device block slides on the outer wall of the central positioning block, with its position and radius corresponding to the position and inner diameter of the positioning hole. A bolt is rotatably connected in the positioning hole, and a magnetic ring is fixedly connected at the slot of the positioning hole. The magnetic block is magnetically attracted to the outer wall of the magnetic ring, and a sealing device is installed on the outer wall of the magnetic block. This utility model, through the magnetic attraction between the magnetic block and the magnetic ring and the expansion sealing design of the airbag, can effectively prevent dust, rainwater, oil and other impurities from entering the positioning hole, avoiding direct exposure of the bolt to the external environment. It fundamentally solves the problem of corrosion and loosening of traditional wheel hub bolts caused by impurities, and improves the reliability and service life of the bolt connection.
