Why does the steering wheel hit at a speed? Beats the steering wheel at a low speed

Almost every car owner in the process of driving many times encountered various beats or vibration on the handlebars. More often the problem appears when driving at fairly high speeds. Another problem with this plan is that the steering wheel beats at a speed below 70 kilometers per hour. Most often this problem happens on cars of domestic production. But foreign cars are not insured against vibrations. Well, let's look at the peculiarities of this problem and the reasons for its occurrence.

What is the vibration on the steering wheel?

This phenomenon occurs on completely different models of cars, regardless of their brand and price. So, the vibrations are felt on the steering wheel or on the body when driving at a speed of no higher than 70 km / h. But it can be completely different. On some cars, the rudder hits at speeds above 40 km / h, on others at 20. When speeding from 100 and above, the vibrations may completely disappear or appear only within a certain speed range.

Snow or mud in the wheel

This is the most common problem. Sometimes vibrates not only the steering wheel, but the entire body of the car. Most often, this phenomenon occurs due to getting into the disk a piece of dirt or snow. After the acceleration to a certain speed, the beats are lost. Vibration may or may not occur again.

If the car is a light alloy wheels, then you can see the dirt in them easily. With stamped wheels, this is more difficult. Usually dirt and snow accumulate on the back of the wheel. You can correct the situation by shooting down snow or dirt from the inner shelf.

Unbalanced Discs

One of the reasons when the steering wheel hits at speed, maybe the wheel itself. Often even a new product has a non-ideal form. Also there are serious inconsistencies in the composition. Therefore, the weight differs in different areas. The central part of the wheel stretches to where there is more mass. This is a centrifugal force. Since the center will constantly shift, the centrifugal force also changes direction. Therefore, the steering wheel will vibrate through the chain of steering links at high speeds.

The problem is solved by balancing the wheels. It is best to do this immediately after changing tires or disks. The balancing process is the equalization of the weight of the wheel at all points. Experts install on the reverse side of the disc special weights, equalizing the mass. The main sign of disturbed balancing is that the rudder drives at high speed. But this phenomenon also occurs at low speeds. In this case, experts recommend a thorough visual inspection of each wheel separately. If there are no dents, tires without damage and beating are felt only on the steering wheel, then the problem is the imbalance.

Deformation of tires and wheels

The degree of their deformation greatly affects the beat or vibration. The disc can be damaged by inaccurate driving through pits and bumps. A curved wheel can be identified by visual inspection. They look at the rim of the disk and look for dents. Most often, deformations are on the inside of the disk. Cast discs, in contrast to the stamped ones, are deformed much less often.

Therefore, if the steering wheel hits at speed, you should carefully check the wheels. The disc may be crumpled. It is also recommended to check the wheel on the stand. But this is not always possible to reveal the curvature. If the wheel is very crooked, then this will be said by the vibration throughout the body. If the discs have old or deformed rubber, then this is one of the reasons for the shaking. At the same time, the body can vibrate. Symptoms can be confused with deformed discs. So, at low speeds can only hit the steering wheel. With the speed dial the steering wheel and the body will shake. The more this deformation, the more significant the vibrations will be. They are also felt at low speeds. The solution is to replace the discs or tires.

Pressure in the wheels

If the rudder hits at speed, then this may be due to different tire pressures. Most often the body vibrates in this case. On the steering wheel the beat is transmitted less often (it just leads to the side). It is enough to equalize the pressure in each tire.

Insufficiently fastened wheels

This reason, unlike all the main ones, can be dangerous. If the nuts that hold the wheel on the hub are loose, the wheel may fall off during the movement. This is a direct threat to the driver and his passengers.

If you hit the steering wheel at a low speed, then the reason is worth looking for including here. But most often this is not done, but in vain. If a weak fastener is not found in time, then after a certain time the motorist is threatened with the replacement of hubs, disks and other elements.

Suspension and steering

Excessively worn out parts of the car's suspension strongly affect how the machine contacts the road. Ball joints, tie rods, hub bearings have a certain backlash. In the process of movement, they can lead to an imbalance. That's why it hits the wheel at speed.

Sometimes all the suspension elements are susceptible to deformations: silent blocks, levers, stabilizer. If everything is fine with rubber and wheels, but hits the steering wheel at a low speed, then you need to check and replace the worn out parts of the chassis. Often, vibrations at low speeds occur due to backlashes in the rack. It is recommended to check the steering rods.

Vibrations during braking

If the brakes at the speed of beating the steering wheel, there are three reasons:

• Curves of the wheel.
• Broken wheel bearing.
• Worn brake discs.

If the brake disc is a curve, then the shoe repeats the shape of this surface. Thus, because of the curvature, the wheel rotates with a figure eight. This happens due to large inertia. If you start to swing the wheel, it will resist. At speed, this resistance is particularly high. Therefore, vibrations are felt on the steering wheel and on the pedals.

Also, the brake disc may become deformed due to overheating. The same symptoms are given by a broken wheel bearing, which can not hold the wheel smoothly, and especially when braking.

Conclusion

We have considered the main reasons why the wheel hits speed, and also when braking. Symptoms indicate problems that can be eliminated with their own hands or at the nearest tire shop.
