Aluminum alloy wheel shortcomings
This kind of wheel hub is slightly less durable and cannot be repaired once it encounters a hard object collision.
Aluminum alloy wheels are available in 1-piece, 2-piece and 3-piece versions.
Safety
For high-speed cars, it is not uncommon for punctures and brakes to be degraded due to high temperatures caused by deformation and braking of steel hubs. The heat transfer coefficient of aluminum alloy is three times larger than that of steel and iron, and the heat dissipation effect is naturally much better, thereby enhancing the braking efficiency, improving the service life of the tire and the brake disc, and effectively ensuring the safe driving of the automobile.
Comfortable
Automobiles equipped with aluminum alloy wheels generally use radial tires. The cushioning and shock absorbing performance of radial tires is superior to that of ordinary tires. In this way, the comfort of the car will be greatly improved when it is on an uneven road or at a high speed.
Energy saving
Since the aluminum alloy wheel is light in weight (about 2 kg from the aluminum or steel hub of the same specification) and has high manufacturing precision, the deformation is small at high speed and the inertia resistance is small. This is beneficial to improve the straight running performance of the car and reduce the rolling resistance of the tire, thereby reducing fuel consumption.
2 How to choose the “excellent” and “bad” of aluminum wheels:
Excellent: Aluminum wheels have gradually replaced the position of steel wheels because of their light weight, good heat dissipation and good appearance.
The light weight reduces the self-weight of the whole vehicle; the heat dissipation is good, and the heat of the brake can be dissipated in time to avoid the brake heat decay and affect the driving safety. When driving, the silver line passes like a light foot.
Inferior: Aluminum alloy is brittle, it is easy to appear small cracks, and it is not easy to be found. Its strength is not as high as steel material. There may be sand holes in casting. The tubeless tires are prone to loss and the price is relatively high.
The basic principle of choosing a hub or hub cap - must be easy to clean.
Don't blindly pursue beautiful, complex hubs or hubcaps that are cumbersome to wash. Beautiful, simple and easy to clean is the best.
1, quality and safety performance. When buying, look for the brand.
2, the bright surface of the wheel mainly depends on the surface and the inner circle whether there is a pinhole. If there is a pinhole, it indicates that there is a problem with the casting quality of the product. Then, if there is any crack, whether there is a tingling feeling on the back of the finger or not, and whether the non-machined surface of the wheel is smooth is also a sign for judging the quality of the brand.
3, the contrast of the paint surface brightness, good brand paint gloss is vivid, and some brands make people feel dull. In coastal or wet snow and ice areas, choose a fully coated aluminum ring that is not easily corroded.
Because of the high price of the aluminum alloy material, there are many people who use the wheel hub cover to beautify the wheels. These wheel hubs are often used to "pretend" aluminum wheels. If you really want to buckle the hubcap as long as the caliber is the same, any car's hubcap can be used. For example, 14-inch, then Audi, Passat, Tianba, Corsica and other car covers can be used, just pick what you like. Since the price is cheap, you should choose a relatively good quality. If a dozen yuan is broken in a few days, it is still not worthwhile.
3 production technology casting
Low pressure casting is the most basic method for producing aluminum wheels and is also economical. Low-pressure casting involves casting molten metal into a mold and hardening it. Counter-pressure casting is a more advanced casting method. The suction generated by high vacuum sucks the metal into the mold, which is beneficial to maintain the constant temperature and eliminate impurities. There is no pore in the casting and the density is uniform and the strength is high. The aluminum wheel hub produced by the high pressure die casting (HCM) process is almost the same as the forged one. The RX/RY (15-20 inch) series aluminum wheel of the German factory BBS is cast by HCM method.
Aluminum alloy wheel
forging
Forging is the most advanced method of manufacturing aluminum wheels, pressing an aluminum ingot under heat to a wheel hub at a pressure of 62.3 MN. The strength of this aluminum hub is three times that of a typical aluminum hub, and the former is 20% lighter than the latter. Some wheels with beautiful shapes and relatively complicated structures are often impossible to forge once. Roll forging (also called die forging) is a type of forging that forges a blank of a hub into a roll. Roll-forged hubs can reduce thickness while maintaining sufficient strength. The aluminum alloy wheel hub manufactured by this process has a uniform density, a smooth surface, a thin wall, a light weight, and can withstand a large pressure. However, since this product requires relatively sophisticated production equipment and the yield is only 50%-60%, the manufacturing cost is slightly higher and the price is naturally not low.
4 maintenance methods
When the temperature of the hub is high, it should be allowed to cool naturally before cleaning. Never use cold water for cleaning. Otherwise, the aluminum alloy wheel hub will be damaged, and even the brake disc will be deformed to affect the braking effect. In addition, cleaning the aluminum platform gold hub with a cleaning agent at high temperatures will cause a chemical reaction on the surface of the hub, which will lose its luster and affect the appearance. When the hub is covered with hard-to-remove tar, if the general cleaning agent does not help, try to remove it with a brush, but do not use a hard brush, especially an iron brush, to avoid damaging the hub surface. Here, the private car owners are introduced to a remedy for removing tar: that is, using a medicinal "active oil" to rub, you can get unexpected results, give it a try.
1.洗去附着在轮毂表面的沙子和容易损坏轮毂的污垢，否则会腐蚀并损坏合金表面；
2.用耐酸清洁剂处理轮毂的内表面和外表面。最好每两个月向轮毂上涂一次蜡，这样可以延长轮毂的使用寿命；
3.为了不损坏轮毂表面本身的保护层，不能在轮毂上使用油漆增白剂或其他研磨材料。当合金保护漆损坏时，如果在行驶过程中在硬物上划伤，则应在专业维修站尽快修理并重新涂漆合金轮毂。

6个优点和缺点
的 铝合金轮毂汽车由铝合金制成的，其生产过程分为铸造和锻造。
铝合金轮毂分为以下四个特点：
1提高驾驶舒适性。铝合金轮具有吸收振动和回弹力的金属特性。数控机床的尺寸精度，圆度高，偏航小，平衡性好，使汽车运行平稳舒适。
2正常行驶，节省燃油。由于铝合金车轮的重量，减少了四轮旋转惯性，提高了汽车的加速度，并且相对减少了制动能量需求，从而减少了燃料消耗。
3提高驾驶安全性。铝合金轮毂的分散系数是普通钢轮的二至三倍。连同铝合金轮毂的结构特征，很容易将轮胎和制动系统产生的热量散发到空气中。中。即使在长时间行驶中连续制动的情况下，车轮系统也可以保持适当的温度。
4提高整车的美观性。铝合金轮毂设计精美，形状多样。它可以使汽车和轮毂结合在一起并变得完美。提高整车的美观性。
5提高行驶稳定性。轮胎加宽以提高抓地力，制动性能，并有效提高驾驶的操控性和驾驶乐趣。
铝合金轮毂也具有某些缺点，如下所示：
1高成本。更换铝合金轮毂需要大量金钱。
2由于改型轮胎的扁平率低，因此改型后的车辆减震器略有硬化，因此有轻微的振动和硬化感。
3增加轮毂的尺寸会稍微增加燃油，但是更换品牌轮胎不会改变燃油。
