As one of the important components of the trolley case, wheels are always related to the ease of use of the trolley case. No matter how good the case is without the wheels, the box is also 'arable land'. So, what type of wheel is better for the trolley case? Let's listen to how the author of the bag answers this question. At present, there are three common types of trolley case wheels on the market, which are divided into one-way wheels, universal wheels and brake wheels. Each of these three wheels has advantages and disadvantages. Let's take a look. 1. One-way wheel The bearing of the one-way wheel is relatively large and stable, and it is strong when dragging on the bumpy ground. The disadvantage is that it can only be pulled away, and the arm will sore when pulling the suitcase for a long time. The advantage is that when you stop standing, you will not run around due to inertia or gravity. In addition, in the case of the same material, the impact resistance of one-way wheels is higher than that of universal wheels and aircraft wheels. 2, universal wheel universal wheel is a wheel that can rotate horizontally 360°, the disadvantage is that it is not easy to fix. The advantage is that it can be pushed and pulled freely when walking on smooth roads, which saves effort. When the luggage is heavy or the passage is narrow, the universal wheel is a great advantage. This is also the main reason for the gradual elimination of single-row wheels in the market. In appearance, universal wheels are divided into ordinary universal wheels and airplane wheels. The aircraft wheel first has 8 wheels, and the grip is firmer, so choose the 28-inch and 30-inch large-capacity boxes, and it is more appropriate to choose the aircraft wheel, which is both strong and stable. 3. Brake wheel The brake wheel has an additional function on the basis of the universal wheel: it can brake. It can also be summed up in one sentence: 1 second lock, stop when you go. This is the general trend in the design of the rear luggage rollers. At present, the form is also divided into foot brake type and knob type. I personally feel that the knob type is more convenient. The foot brake type is easy to get stuck on the wheels and cause failure. Customized trolley cases, look for custom luggage manufacturers!
