How much does a hub impact affect the suspension? To what extent can the hub be knocked out of use

The hub, if only a slight hit, does not have an excessive impact on the suspension. If the impact is more serious, you need to go to the repair shop for testing, do a four-wheel alignment inspection, etc.

To what extent can the wheel hub be knocked can not be used, generally mainly to see the degree of deformation and fracture of the wheel hub, in the case of the wheel hub to deformation or breakage, put the tire on the balancing machine instrument for testing, if the tire jumps, the tire can not continue to be used. Generally, when the wheel hub is disguised or broken, it can be repaired in the way of repair, if not, it will be replaced with a new wheel, and the four-wheel alignment test is also needed after replacing the wheel.

Generally, if the tire hits the road, it will have a certain impact on the tire, wheel, suspension and suspension, and in serious cases, it will damage the tire, resulting in tire sidewall bulge, puncture, wheel deformation, and may damage the suspension to cause body deformation, and there will be abnormal noise during driving.

In addition to not hitting the road teeth, you must also learn to use the road teeth correctly, otherwise the road teeth will also cause damage to the chassis, suspension and shock absorbers of the car. For example, estimating the gap between the wrong road tooth and the chassis will cause the chassis to drag to the bottom.

In addition, if you park across the road for a long time, the suspension will be unevenly stressed, resulting in abnormal wear and tear.

The former problem cannot be explained by numbers, it can only be said that the problem will not occur within this range if the basic allowable stress calculation is made along with the design requirements during the design of the specific vehicle type. However, the actual types of vehicles and accidents are ever-changing, and it is impossible to say whether a certain impact is beyond the design scope of a certain car type. This can only be confirmed by post-accident testing.

For whether the wheel hub will continue to be usable after the accident, there are three main points. One is deformation (including radial runout and axial swing); One is cracks; One is the imbalance of the dynamic balance.

It should be pointed out here that it is easy to ignore the detection of deformation in general inspection, thinking that as long as there are no cracks and the dynamic balance is no problem, it can be used, so that it is not enough to use visual inspection without detection.

It has a great impact, and if it is not repaired or replaced in time after its deformation, it is likely to cause direct fracture of the wheel hub due to hitting an obstacle during driving, which is very dangerous.

As a metal substance, aluminum alloy can be restored to a straight line after a wire is bent, but it will be broken after two or three attempts, not to mention such a large wheel. If the wheel is forcibly restored to its original state, although it looks the same as new from the outside, its internal organization is already very fragile, and if the position repaired during driving is hit again, the wheel hub will directly break and cause a serious traffic accident.

The repair method is to put the recessed part on the sponge, cloth, etc., and then use a hammer to vigorously smash the recessed part flat. Don't worry, you can use putty, which is commonly known as putty, which is used for leveling when the sheet steel is painted, and it is used on the wheel hub to find the circle, and after the uneven position is repaired and leveled, then use sandpaper to beat the inside of the wheel to prepare for the next step of painting.

Let the putty dry in the sun, and the next step is the same as painting a car. Because the original wheel hub is the color of the aluminum alloy itself, it cannot be achieved by any paint, so it can only be sprayed. The inside of the wheel is sprayed with automatic paint close to the original color of the wheel, and after the paint is dry, a "new" wheel is born.

Because as mentioned above, professional masters usually do not recommend repairing, and it will be safer to replace it directly with a new one.

Summary. Dear, I'm glad to answer for you, the car hub cap was lightly knocked down from the side, which will hurt the shock-absorbing suspension, but the damage is not great. If the tires and wheels are fine, it means that the collision is very slight.

If the car hub cap is knocked down from the side, will it hurt the shock absorbing suspension bearings or something?

Hello master. Dear, I'm glad to answer for you, the car hub cover was quietly knocked down from the side of the year, which will hurt the shock absorber suspension, but the damage is not big. If the tires and wheels are fine, it means that the collision is very slight.

The headlight casing cracked.

The impact force is quite large.

If the headlight shell is broken, go to the repair shop to find the auxiliary factory shell to replace it.

I'm Hongqi Che.

The 4S shop said that there was a problem with shock absorption and horn bearings.

Even if the tires or wheels are damaged (some large wheels will stick to the wheels in the pit edge collision moderation), the transmitted energy will basically be absorbed by the shock absorbers, and the parts that fail to absorb the vertical macro will reach the suspension system, and the suspension system will fight with its own rigidity and toughness.

If the wheel hub is hit by an external force, resulting in shock absorption deformation, it will lead to oil leakage.

If the wheel hub is a mild collision, it will cause too much harm to the suspension system. If the collision is obvious, it is necessary to go to the repair shop to carry out inspection, do four-wheel alignment inspection, etc.

What levels of the wheel hub can not be used, generally mainly to see the deformation and fracture level of the wheel hub, the wheel hub knocks on the deformation or fracture of the situation, put the tire into the dynamic balancing machine equipment to achieve inspection, if the tire flutters, then the tire can not be used in the future. Generally, when the wheel hub changes direction or breaks, it can be applied to the form of repair, and the form of repair can be used to carry out maintenance, if it is not good, the new hub will be replaced, and the four-wheel alignment inspection must also be done after the wheel hub is replaced.

Generally, if the tire knocks down the road, there will be certain harm to the tire, wheel, suspension and shock absorption, and in more serious cases, the tire will be damaged, resulting in tire wall packing, tire puncture, wheel deformation, and it is also very likely to damage the suspension system to cause deformation of the car body, and abnormal noise will occur during the driving process.

In addition to not knocking down the road teeth, it is also necessary to master the proper use of the road teeth, otherwise the potato-based hand road teeth will continue to cause several hazards to the vehicle's car chassis, suspension and shock absorbers. For example, estimating the gap between the wrong road and the chassis of the car will cause the chassis of the car to drag to the bottom.

There are also long-term parking across the road, which will cause the suspension to bear uneven capacity, resulting in abnormal damage.

Millions of car purchase subsidies.

If the hub is only slightly impacted, the impact on the suspension will not be significant. If the impact is more urgent, you need to go to the repair shop for inspection, four-wheel alignment inspection, etc.

To what extent the hub cannot be used, most of the key points are the degree of deformation and fracture of the hub. When the hub is deformed or broken, place the tire on the balancing machine for inspection. If the tires jump, the tires will no longer be used.

If most of the wheels can still be used in disguised or broken condition, they can be repaired by way of repair. If not, replace the wheels with new ones. After replacing the hub, a four-wheel alignment check is also required.

Most of the time, if a tire hits a curb, it will basically have some impact on the tire, hub, suspension, and shock absorber. If it is an emergency, it will damage the tire, causing the tire sidewall to bulge, puncture, wheel deformation, and may also damage the suspension, affect the deformation of the body, and there will be abnormal noise during driving.

In addition to being sure not to hit the curb, you must also learn to use the curb accurately, otherwise the curb can also cause damage to the car's chassis, suspension, and shock absorbers. For example, an incorrectly estimated gap between the first tooth and the chassis can cause the chassis to drag to the bottom. Also, if you park across the road for a long time, the suspension will be subjected to uneven stress, resulting in abnormal wear.
