The difference between wheel rims and hubs

In fact, it can be regarded as the same thing by ordinary people. Then the professional distinction is that the rim is a part of the hub, that is, the outer ring of the hub, the part that is in the most direct contact with the tire, and the main body of the hub is the fixed part that connects the accompaniment and the bearing. Make up the wheel we see, also collectively referred to as the hub. Most of them are non-removable, one is prosperous and one is damaged, so it is good to understand it as the same thing.

Rather than understanding the difference between what is originally the same thing, you might as well understand the types of wheel hubs. Common common vehicles on the market are mainly cast iron or cast steel, and low-pressure casting is used. Most of the conscientious models or high-end models will use aluminum alloy wheels, and some supercars or performance cars will be equipped with aluminum alloy forged wheels, which are lighter in weight and higher in strength. Everyday acceleration, economy, top speed stability are all good. The lesser one is the rotary die-casting hub, which is weaker than forged hubs, but stronger in toughness and slightly heavier.

Let me share a little knowledge with you.

Spinning cast wheels are favored by many car owners because of their high cost performance and do not need to sacrifice a lot of appearance design due to the physical reasons of forging technology, but they are more easily deformed than forged wheels because of their weaker strength. Here I will tell you that the rotating die-casting wheel hub, because of its extremely high toughness, can withstand smaller deformation, is less likely to break than the forged wheel hub, and suffers less damage under the same damage, in the hands of professional manufacturers or maintenance technicians can be repaired. After the forged wheel is damaged, the repair cost and difficulty are also higher.
