Hub is a very inconspicuous parts, with the equipped with wheel hub of the vehicle number less, even only a spare tire will choose the wheel hub, many consumers have not too much attention of the components, but some knowledge about the proper understanding of the hub, or for buying a car and the car help.
What is the hub?
The hub is also called the wheel rim, tire bell, metal component of the tyre inner support tire drum shaped, arranged on the shaft center. According to the wheel diameter, width, forming method, different kinds of materials. Hengding hub said that simple point that is your visual vehicle side is, the entire wheel part, rubber tire outside place aside, basically can be regarded is the hub of the!
The classification and characteristics of the hub
In accordance with the material to the hub, which can be divided into: wheel hub and two kinds of alloy wheels.
1, wheel hub
The wheel hub of the models are generally based on cost considerations, it is because of the low cost of the wheel hub, manufacturing process is simple, with respect to the alloy wheels, wheel hub more rugged; drawback is heavy weight, large inertia, is not conducive to saving, also by on the problem of the structure steel ring hub, resulting in the heat dissipating efficiency than alloy material, is not conducive to the brake heat conduction may will cause a decline in braking efficiency. Also equipped with wheel hub of the owners do not long term parking, try for a week to wiggle your vehicle, to prevent the occurrence of irreversible situation of wheel hub with slight deformation occurred.
2, alloy wheels
Said alloy wheels points for forging and casting in two forms, in addition to the original process, now and a new process called mat spinning casting, here not much said the difference between them the Hengding hub. Alloy wheels of obvious advantages, light weight, beautiful appearance, beneficial to the heat dissipation, small inertia, high manufacturing precision. The disadvantage is that the relative cost of steel ring is a bit high, considering the cost of car enterprises will abandon alloy wheels, manufacturing process is relatively rim makes it more complicated, appearance is easy to bump damage.
Because of the particularity of the wheel hub hub, so maintenance we say here is mainly about the alloy wheels.
If just ran all the way after the vehicles, don't immediately wheel cleaning, because we in the driving process, with the warming of the tire and brake, the wheel hub of the temperature increased, the proposed parking for a period of time, the temperature down for cleaning operation.
Hub is very near the road and close to the brake disc, so the wheel is often easily dirty parts, is usually left after pavement thrown up the dirt and brake disc brake powder, do not recommend the use of excellent brush to clean, use special cleaning fluid supplement soft brush is easily adhere to the above the dirt washed off.
Hendin hub to remind the drivers, we should pay attention to avoid the potholes sections, with slow or slow down by. Especially in the wheel hub, if fast through the hollow sections is likely the steel becomes irreversible deformation, once the deformation may in high speeds occur body beat, affect the vehicle driving stability. Although the alloy wheels are not easy to deform, but once a slight deformation need to be done in the dynamic balance of the vehicle, the deformation is more serious need to replace the wheel.
Not a long time parking, a week recommended appropriate dodo vehicle to prevent deformation of the wheel hub, can also prevent the tire of irreversible deformation occurred.
Can the wheel hub damage be repaired?
The answer is yes. Hub a slight rub will immediately repair, if rub is more serious to see if reveal the primer, if reveal the primer and need to immediately repair do not delay, once the delay will lead to corrosion, resulting in unable to repair.
Generally speaking, the gap is not more than 3 cm construction. Repair must go to the regular store, according to the damage size is different, the patch will be different, the processing of the wheels generally need to be dynamic balance.
