Hub modification, single or multiple?

Many car owners may have such experience: when refitting to choose the wheel hub, not only a variety of styles let a person dazzling, in the hub, two, three pieces of the difference also let a person difficult to distinguish.

In fact, according to the structure of the hub can be divided into one and more pieces, if you want to change the forging hub, how should you choose?

One - piece forging wheel hub

A piece of the wheel hub is the whole hub is a whole, forged and polished with the same piece of aluminum alloy, also known as a single piece, is the most common hub.

The advantages of the one-chip is relatively light weight, and more dynamic balance of the chip is good, good reliability, no potential leakage; The disadvantage is that the product development early investment is high, relatively simple modeling.

Multi - chip forging wheel hub

Multi - chip hub is divided into two - chip and multi - chip. The two-piece forging hub consists of two parts, the rim and the wheel width, which are bolted together.

Threepiece hub: the rim portion consists of two parts: the front (inner) and the back (outer). Therefore, the threepiece wheel hub is composed of the front piece, the back piece and the wheel width, and the sealing glue shall be used to ensure the air tightness after assembly.

There are two main ways to connect the hub and rim in multi-chip forging:

(1) special bolt/nut connection

Welding (Japanese big wheel WORK two-piece wheel is the use of this process)

Multichip models can combine rings of different widths and thicknesses on a hub, or combine widths and offsets for more options. This means that the spokes can be interchanged. For example, if the spokes are broken or you want to change the spokes, you don't need to replace the whole hub. You just need to replace the broken part and tighten it with high-strength bolts.

Due to the complicated process of multi-chip wheel hub, the manufacturing cost is relatively high. However, in the production process of forging wheel hub, due to the continuous stamping of aluminum block, its molecular structure will become very tight after forming, so it can withstand higher pressure.

Further, because the structure of the forging wheel hub is tight, can withstand high stress, so in the modeling design, it can design some more lively fine spokes, the design degree of freedom is higher.

In general, wheel hub modification, if the pursuit of personalized, you can choose the multichip model; If there are no special requirements, you can choose according to their own preferences.
