Hub: also called rim. English RIM, namely the meaning of car hub. As part of the axle mountingFeng machine tool spindle wheel center, is connected with a brake drum (or brake disc), an important part of disk and semi axis. It uses bearing is sleeved on the shaft tube or a steering knuckle shaft neck.
As Feng Machine Tool Spindle said hub is mainly from the manufacturing process is divided intotwo kinds of casting and forging, general casting ring is aluminum, and forged aluminum, also has a titanium metal plus. Generally speaking, forging ring strength, racing is forged, a forging ring used for racing is equivalent to half of our common casting ring weight, the more weight, vehicle powerloss is small, run faster.
Another difference index hub hole distance and eccentricity is different. The hole distance is simplythe screw position, eccentricity is reflected is the hub for screw surface (fixed surface) to the hubcenter line distance. As Feng Machine Tool Spindle represents a good hub requirements are:uniform density, morphology, thermal deformation of small circle, big intensity.

The hub can be updated, some people put their own cars to upgrade, use a larger wheels, but thetire diameter constant law, flat tire change, the transverse swing small car, stability is improved, but the car lost is comfort.
The protection of the hub
Senior car wheel hub are for aluminum alloy materials. As Feng Machine Tool Spindle said this hublooks beautiful, but also very fragile. To keep the wheel appearance beautiful, but be careful to prevent accidental injury hub in the driving process, but also regularly carry out maintenance and repair of the wheel. If there is time should conduct a thorough cleaning every week.
1, wash away the wheel attached to the surface of the sand and easier for the hub damage caused by the dirt. Otherwise, alloy surface will be subjected to corrosion and damage. 2, acid cleaning agent for inside and outside surface of wheel processing. The best every 2 months to the hub on awax, it can prolong the service life of the wheel hub.
As Feng Machine Tool Spindle remind note: in order to protect layer without damaging the surface of the hub itself, not on the wheel to use. |
