行李箱輪子是旅行箱的重要部件，也是最容易磨損和故障的部件。因此，我們需要定期對行李箱輪子進行保養，以延長它們的使用壽命，並提高拖行的順暢性。根據我從網路上搜尋到的資料，以下是一些保養行李箱輪子的方法：

清除異物：如果輪子卡進了頭髮、細石、貼紙等異物，會影響輪子的轉動和平衡。我們可以用美工刀、髮夾、刮刀等工具，小心地將異物割出或勾出。
擦拭乾淨：如果輪子沾染了泥土、水漬、油漬等污垢，會增加輪子的摩擦和磨損。我們可以用濕布沾取中性清潔劑或去漬油，輕輕地擦拭輪子和輪座。注意不要用去光水或強酸鹼的清潔劑，以免損傷行李箱的表面。
加注潤滑油：如果輪子轉動不順或發出嘎嘎聲，可能是因為軸承生鏽或缺乏潤滑。我們可以用萬用針車油或其他適合的潤滑油，在軸承處加注少量的油，讓輪子恢復運轉順暢。
更換新輪：如果輪子已經磨損嚴重或者斷裂，則需要更換新的輪子。我們可以自己在網路上購買適合的輪子，然後用起子或扳手等工具，將舊的輪子卸下，再安裝新的輪子。也可以送到專業的維修店，由專人更換。
正確使用：除了定期保養外，平時使用行李箱時也要注意正確的方式。例如，在不平坦的路面上要用斜拉的方式拖行，避免用平推的方式造成單邊磨損；收納行李箱時要平放，避免讓輪子承受過多重量；在雨天或潮濕的地方使用後要及時抹乾水分，避免讓輪子生鏽24。
以上就是我找到的一些保養行李箱輪子的方法，希望能對你有所幫助。

Suitcase wheels are an important part of a suitcase and are also the most susceptible to wear and failure. Therefore, we need to regularly maintain the suitcase wheels to extend their service life and improve the smoothness of towing. Based on the information I searched on the Internet, here are some ways to maintain luggage wheels:

Remove foreign objects: If hair, fine stones, stickers and other foreign objects are stuck in the wheel, it will affect the rotation and balance of the wheel. We can use utility knives, hairpins, scrapers and other tools to carefully cut out or hook out 12345 foreign objects.
Wipe clean: If the wheels are stained with dirt, water stains, oil stains and other dirt, it will increase the friction and wear of the wheels. We can use a damp cloth dipped in neutral detergent or scouring oil to gently wipe the wheel and wheel seat 12345. Be careful not to use polishing water or strong acid-base cleaners to avoid damaging the surface of the suitcase5.
Lubricate: If your wheels spin sluggishly or make a rattling sound, it could be because the bearings are rusty or lack lubrication. We can use universal sewing oil or other suitable lubricants and add a small amount of oil to the bearings to restore smooth running of the wheels.
Replace with new wheels: If the wheels are severely worn or broken, you need to replace them with new ones. We can buy suitable wheels on the Internet, and then use tools such as screwdrivers or wrenches to remove the old wheels and install new ones. You can also send it to a professional repair shop and have it replaced by a dedicated person2.
Proper use: In addition to regular maintenance, you should also pay attention to the correct way when using your luggage. For example, when towing on uneven roads, use a diagonal pull method to avoid using a flat push method to cause unilateral wear; when storing suitcases, keep them flat to avoid letting the wheels bear too much weight; in rainy or humid places Moisture should be wiped off promptly after use to prevent the wheels from rusting.
The above are some of the methods I have found for maintaining suitcase wheels. I hope they can be helpful to you.
