Universal wheel for luggage: the universal wheel in luggage is also called Vientiane wheel, which is actually a wheel that can rotate 360 degrees. No matter whether the wheels are single-row or double-row, as long as there are four wheels, they can be called universal wheels, so aircraft wheels are also universal wheels!
One-way wheel for luggage: some people also call it directional wheel for luggage. This kind of wheel has only two wheels, so it can't just rotate 360 degrees, only go straight!
Luggage mute wheel: The name of luggage mute wheel is mainly due to the material problem. When the box is pulled on the ground, the sound is very light, almost silent, so it is called silent wheel!
The differences among suitcase universal wheel, airplane wheel and one-way wheel are as follows:
Price Comparison of Aircraft Wheel, Universal Wheel and Unidirectional Wheel
Generally, aircraft wheels are silent rubber wheels, so they are basically silent. The dimensions of aircraft wheels have not changed much, basically larger than universal wheels and smaller than unidirectional wheels. Universal wheels are made of various materials, including silent rubber wheels. Aircraft of the same specification have more wheels than universal wheels. Because airplane wheels use two edges, they are generally more expensive than universal wheels. The whole airplane wheel suitcase is also more expensive than the universal wheel suitcase. Universal wheels use four wheels, and one-way wheels only use two, so one-way wheels are the cheapest.
The difference between universal wheel and airplane wheel and silent wheel: the main difference between universal wheel and airplane wheel lies in the shape, and the difference between universal wheel and silent wheel lies in the material. Generally speaking, as long as there are four wheels, no matter what material is used, it can be called an airplane wheel, and as long as there are four wheels and eight sides, it can be called an airplane wheel, so the airplane wheel must be a universal wheel, which is different from the airplane wheel, as long as it is rubber, regardless of the airplane wheel.
Aircraft wheels, universal wheels and one-way wheels are suitable for road conditions: aircraft wheels and universal wheels are more suitable for smooth intersections, such as airports, where the ground is flat and smooth, and the suitcase of universal wheels can be pushed and pulled, which is very convenient; If you choose one-way wheels on rugged mountain roads or dirt roads, the wheels of one-way wheels are generally larger and easier to pull up, and one advantage of one-way wheels is that they are more durable than universal wheels. For example, the damaged wheels of the plane consignment are universal wheels, because all four wheels of the universal wheel are missing, and a part of the unidirectional wheel is missing.
Therefore, when transporting luggage by air, the one-way wheel is more durable than the airplane wheel, and the airplane wheel is more durable than the universal wheel! Material selection of aircraft wheel, universal wheel and unidirectional wheel;
1. Selection of wheel material: First, consider the size of the road surface, obstacles, residual substances (such as iron filings and grease) at the site of use, environmental conditions (such as high temperature, normal temperature or low temperature) and the weight that the wheel can bear to determine the appropriate wheel material. For example, rubber wheels cannot resist acid, grease and chemicals, while super polyurethane wheels, high-strength polyurethane wheels, nylon wheels, steel wheels and high-temperature resistant wheels can be applied to different special environments.
2. Calculation of bearing weight: In order to be able to calculate the bearing capacity required by various casters, it is necessary to know the self-weight, maximum load of transportation equipment and the number of single wheels and casters used. When calculating the load of a single caster, a certain safety factor should be given. When the ground is relatively flat, the load of a single caster = (total weight of equipment? Number of casters installed)? 1.2 (insurance factor); If the ground is uneven, the algorithm is, single caster load = total weight of equipment? 3, because no matter what kind of uneven ground, there are always at least three wheels supporting the equipment at the same time. This algorithm is equivalent to increasing the safety factor, being more reliable, and preventing insufficient load bearing, which will greatly reduce the service life of casters or lead to accidents.
3. Determine the wheel diameter: Generally, the larger the wheel diameter, the easier it is to push and the greater the load capacity, which can protect the ground from damage. The selection of wheel diameter should first consider the load and the starting thrust of the truck.
4. Selection of wheel materials: Usually, wheels include nylon wheels, super polyurethane wheels, high-strength polyurethane wheels, high-strength synthetic rubber wheels, iron wheels and pneumatic wheels. Whether driving indoors or outdoors, super polyurethane wheels and high-strength polyurethane wheels can meet your control requirements; High-strength synthetic rubber tires can be applied to hotels, medical devices, floors, wooden floors, tile floors and other quiet ground when walking; Nylon wheel and iron wheel are suitable for places with uneven ground or iron chips on the ground; Air pump wheel is suitable for light load and uneven road surface.
Comprehensive comparison of aircraft wheels, universal wheels and unidirectional wheels (personal views are for reference only): the existence of each wheel has market demand. At present, no wheel has completely replaced any wheel. Please choose the one that suits you. If you have extra money, you can try to buy boxes with different wheels separately to prepare for buying boxes in the future. Under normal use, the life of hard-shell suitcase is about 5 years, and the life of soft-cloth suitcase is about 10 years!
The most easily damaged parts of the suitcase are the tie rods and wheels.
Pay special attention to these two places when buying;
1, according to the price ratio, from high to low, is a plane wheel universal wheel one-way wheel;
2. According to the durability ratio, from high to low, it is a one-way wheel, an airplane wheel and a universal wheel; 3. According to the cost performance, from high to low, it is universal wheel and one-way wheel aircraft wheel;
