AI Technical Summary
The shaft of the existing automotive cross shaft is exposed during use, making it prone to dirt and sand accumulation, leading to wear, oxidation, and rust, and has poor wear resistance.
A dust cover and an oil scraping mechanism are installed on the shaft. The dust cover blocks external mud and sand, while the oil scraping mechanism drives the oil scraping pad to scrape the lubricating oil on the outer surface of the shaft through the collar and support frame, ensuring that the lubricating oil is evenly applied.
It effectively prevents shaft wear and oxidation, improves shaft wear resistance, keeps shaft surface smooth, and slows down the oxidation process.
