Wheel center caps

Automobile wheels include hub bolt holders, drainage spiral blades and rims. The structural points of the hub bolt holders and rims are provided with drainage spiral blades to drain air to the outside of the hub, but the drainage spiral blades can drive the air flow when the wheel rotates, and the air flow forms wind, but the guide spiral blades guide the air flow from the inside of the car to the outside of the car. The inclined wind guide surface will produce a certain concentration of air during the rotation of the wheel, and will converge with the inclined direction of the inclined wind guide surface. Since the inclined wind guide surface is curved, the support ribs are closer to the fixed seat, and the inclined the wind guide surface. The greater the inclination angle. The support ribs gradually increase the concentration of flowing air from the outside of the rim to the inside, thereby introducing air into the vent, because the vent penetrates the rim, the air can be directly directed to the brake and bearing assembly, effectively improving the heat dissipation effect. The air outlet is located on the side of the inclined wind guide surface close to the center of the rim. The number of support ribs is even. The two support ribs form a triangular structure with the rim. The triangular stable structure is adopted to make the support ribs support the rim more stable, thereby ensuring the safety of the hub.

The selection of wheels, how to choose the best one?Many people will transform the car at will in order to change the performance of the car. The transformation of the car requires professional knowledge. For the wheel rim, we cannot arbitrarily increase its diameter. 1. Don't blindly increase the wheels.Some people increase the wheels to improve the performance of the car. When the outer diameter of the tires remains the same, the large wheels are bound to match the wide and flat tires. The lateral swing of the car is reduced, and the stability is improved. When cornering, it is like a dragonfly, passing lightly.However, the flatter the tire, the thinner its thickness, the worse the shock absorption performance, and greater sacrifices must be made in terms of comfort.In addition, if there are a few roadblocks such as stones, the tires can easily be damaged.Therefore, the cost of blindly increasing the wheel rim cannot be ignored.Generally speaking, it is most appropriate to increase one or two sizes according to the size of the original wheel rim . 2. This means that when choosing, you can't choose your favorite shape as you want, and you have to follow the advice of professionals to consider whether the three distances are appropriate. 3. The wheels with complex structure and dense density are indeed beautiful and appear to be of high grade, but it is easy to be refused to wash or overcharged when washing the car because it is too troublesome to wash.The simple wheels are full of movement and clean.Nowadays, the aluminum alloy wheels that are deeply popular with the people, compared with the iron-cast wheels in the past, the degree of deformation resistance has been greatly improved, the weight has been greatly reduced, the power loss of the car is small, it runs fast, saves fuel and has good heat dissipation. It is loved by the majority of car owners.Here is a reminder that in order to cater to the tastes of car owners, many car dealers replace iron wheels with aluminum alloy wheels before selling cars, but they add a lot to the price.So from the perspective of affordability, don't pay too much attention to the material of the wheels when buying a car. Anyway, you can change it according to your own style, and you can save a fortune in the price. Why not?
