Talk about those things of the trolley case-wheels

Before buying a trolley case, my friends always have doubts about wheels, trolleys, case materials, internal accessories, etc.

If you want to spend less money to buy the most value-added products, it is important to choose a vision. Then you must thoroughly understand a category and know what you need in order to select the most suitable product for you.

So, with the birth of this series of articles.

I hope everyone can take the beloved suitcase and the beloved one, and travel all over the world ~

The first article is about wheels.

(There will be detailed introductions about tie rods, materials, interiors, etc., if you want to know other content, please leave a message, and I will try to answer your questions.)

First introduce the commonly used wheels on the market, in fact, there are three kinds of wheels

♦ Directional wheel (2 wheels)

♦ Universal wheel (4 wheels)

♦ Aircraft wheel (8 wheels)

❀ Note here that the aircraft wheel is actually an 8-wheel universal wheel

The following picture above, look in detail

Installation structure

♦ The structure of the directional wheel is simple, the wheel is oriented, generally buried half in the box, and tightly connected to the entire box.

♦ The box of the universal wheel is fixed at the bottom of the box. The wheel is relatively small and the connection is thin. Compared with the box of the two wheels, it is much higher under the same volume.

The above two points can be intuitively felt from the above picture ~

price

In the case of the same material and the same brand:

Aircraft wheel> Universal wheel> Directional wheel

After all, the number of wheels there is relatively understandable, so I wo n’t say much about the price.

Material

There are really many materials for wheels. Common ones include plastic, rubber, titanium, and iron. There are many types of plastics, such as nylon, PVC, PP, PC, ABS, TPU, etc.

The trolley wheels that are common on the market today are made of plastic, which is more suitable for smooth roads.

You do n’t have to delve into which kind of plastic is used, because in terms of actual use, it really does n’t make much difference ... Unless you will drag a box and walk some rugged mountain roads or the like, it is really a good consideration The wheel material.

(To tell the truth, the roads where most people use trolley cases should be relatively smooth. Except for adventures, it is unlikely that anyone will drag a box to go in the deep forest ...)

If you encounter some special roads and have doubts about the material of the wheels, you can participate in another article.

Those things about wheels

Bearing

Bearing materials are divided into 2 types

♦ Plastic

♦ Steel

Currently, plastics are commonly used on the market, and plastic bearings are capable of handling most road conditions.

As long as the wheels are not made of recycled waste, they can be guaranteed in terms of wear resistance and toughness, but some manufacturers use waste materials to reduce costs, so it is recommended to choose large-brand products. After all, quality control is guaranteed.

So at the end, pick 2 brands, a simple example,

Imported brand: Japan ECHOLAC

Domestic brand: CONWOOD

The wheels of these two brands are made of mainstream TPU + PP

What is TPU?

The name of TPU is thermoplastic polyurethane elastomer rubber. The so-called elastomer refers to a polymer material with a glass transition temperature lower than the chamber temperature, an elongation at break> 50%, and good recovery after removal of external force.

TPU products have outstanding bearing capacity, impact resistance and shock absorption performance, oil resistance, water resistance and ultra-high resilience.

What is PP?

PP is a thermoplastic resin made from the polymerization of propylene. It has the characteristics of wear resistance and corrosion resistance, high impact strength, and good surface rigidity and scratch resistance.

Although the materials are the same, there is still a certain gap in the quality of the wheels due to the manufacturing process and the proportion of ingredients.

ECHOLAC uses the wheels of Japanese HINOMOTOR. The brand is a Japanese manufacturer specializing in the production of rollers. It has a number of patented technologies and is currently widely used by many international brands. Quality is absolutely guaranteed.

Therefore, if you are afraid to buy a trolley wheel that is not easy to use, just pay attention to whether the wheel is made by HINOMOTO. However, boxes using wheels of this brand are generally not cheap. . .

For example, the box price of ECHOLAC brand is between 700-2500. Personally, I recommend TA's Tmall hot-selling model, which may be due to the amount of running. The 20-inch box is priced at 699, and the price is really high.

If the price of the trolley case is within 500, then the wheels are definitely made in China, but as long as you can pick, you can still choose the appropriate price and quality.

For example, most of the products of CONWOOD brand price range between 200-500, there are several models with good value, mainly as well-known brands of domestic luggage, the quality is also guaranteed, at least it will not be bad once used. .

Of course, after-sales is the top priority at all times, so before you decide to buy, be sure to ask after-sales.
