The new energy low speed chassis is abnormal, and there is no faster driving

Hello! Glad for your question.

Loose chassis generally occurs in older cars, when the car is driving in bad road conditions, the steering wheel will feel unstable, the bottom of the car will also come out of the abnormal sound, usually the old driver can feel the overall a little loose, when encountering such a situation, it means that the chassis may be loose, and the reasons for this situation are divided into several, only by understanding the reasons, can we better prevent this problem from happening.

The first reason is the aging of rubber parts, we all know that the elasticity of rubber is particularly good, which can buffer the friction between parts and reduce noise at the same time. However, this kind of thing has a lifespan, and it will age after a long time, and the elasticity is not as good as before, so the buffering capacity will decrease, resulting in abnormal noise in each part, so it is necessary to check these rubber parts regularly and replace them in time.

The second possibility is the reason for the shock absorber, the main role of this part is to inhibit **, when the car is driving in the dustpan section, it will have an impact with the road surface, and the shock absorber can well ensure the smoothness of the car, if the shock absorber is damaged, there will be a scoop phenomenon, so that the chassis is loose, so usually check the shock absorber, if there is a leakage to repair in time.

The third is the clearance of the parts, that is to say, the ball head may be loose, this part is like the joint of the human body, if the ball head is loose, there will be a large gap between the lever and other connected parts, if the gap is too large, when crossing some dustpan roads, the screws between the subframe and the suspension will be loose, then the chassis will become loose, so usually check these two parts. Thank you.

Your car is not disc brakes.

The common problem of disc brakes is only the problem of sound size, and it will be better to wash the brakes with water when washing the car. If you drive fast, you can't make a noise because other sounds are louder than loud sounds.

I guess the brakes are a little tight.

Some are not installed in the spare tire in the trunk, or there are some tools in it, and the road will not ring at ordinary times, you can open it to see if this is the reason, if not, and then hear the sound, then go to the 4S store to check.

Novices look at the indicator light, the light is not on, just turn it on.

You take a look at the back, and if you have a problem, you can fix it.

This situation is generally caused by the controller, and has nothing to do with the motor and rear axle. Your car should have had to replace the controller before it broke down, which is a typical failure without a Hall controller. Replace the original car controller.

Solution: Check the exhaust pipe, it may be caused by the position of the ball head of the exhaust pipe, this kind of abnormal noise is more common, and you need to replace the new exhaust ball head. This kind of abnormal noise will be more obvious when the car is cold, followed by it will be more obvious when changing gears, and the abnormal noise is not easy to appear in high-speed driving, and this sound will not affect the normal use of the vehicle and will not affect driving safety.

Suggestion: After hearing an abnormal sound while driving, drive to the repair station as soon as possible, check it, and replace spare parts, and the chassis should be checked regularly for older cars.

It may be that the plane bearing is broken, you can stop when one person plays the steering wheel in the car, and the other person touches the spring of the shock absorber, such as the spring shakes the hand when playing the direction, indicating that there is a problem with the plane bearing on the shock absorber, you can go to the auto parts city to replace it (save money), if not, you need to go to the auto repair shop to check the power steering pump, lower arm, and steering machine assembly.

Check the moving parts when parked, such as the wheels of the engine, or the sound in the shift. The chassis contains a lot of things, and it is necessary to listen specifically to the sound.

The problem of abnormal noise occurs in the friction between the brake pads and the brake disc, if the abnormal noise does not disappear, it is recommended that you go to a professional repair shop to check and repair, I hope you!

Your car should be a front-wheel drive engine model, and high-speed squeak may be a problem with the front-wheel drive shaft.

Remember, running at a low speed should not want to run at high speed, and there are some qualifications under the front of the car that think that it is not a good thing to be happy, but to run a dart is to run at high speed and try to drive high can be some vibration.

This low speed does not affect the high speed, and there is an item under the side head that may be caused by the failure of the engine bearing shaft, which should be inspected and repaired.

The car does not make abnormal noises when it runs at low speeds, but it makes abnormal noises under the front of the car at high speeds. It may be that there is a problem with the engine, and the engine speed is high when running at high speed, something special happens.

It is recommended to go to the after-sales service of the car, or find a regular auto repair shop with a lift, lift the car, and check whether the chassis of the car is loose or loose.

The car runs at low speed and does not imagine running at high speed, and there is an abnormal sound under the front of the car, which may be a problem with your car, and it may generally be that it cannot be accelerated, so there will be an intention to accelerate, so it is generally only suitable for running at low speed, not suitable for running at high speed.

Hello!

When the car makes an abnormal noise under the chassis at high speed, it is considered that the vehicle shakes at high speed, and then resonates and the sound is generated by interference between parts. You check to see if there are any loose parts under the chassis.

This situation may be due to the loosening of the sealant in the engine or the engine gasket, you can drive to the 4S shop to check the specific reason.

The car runs at low speed and is not easy to run at high speed, and there is an abnormal sound on the front of the car, which may be because there is a problem with the starter, and you can send it to the 4S shop to do a comprehensive inspection, so that if there is a problem, it can be checked out well.

Answer: The low-speed wind speed is relatively small, and some parts of the car will not resonate, and the high-speed relative wind speed is high, and some parts will resonate and form abnormal noise.

First: it is very likely that the gear teeth of the driving wheel are broken, or the surface is damaged, at this time you should pull over to check, if the gear is damaged, you should replace the new gear in time. Second:

It may be the abnormal sound caused by the loosening of the connecting parts of the wheel, and the transmission of the wheel has many gears, and if it is too loose, it will make a noise when cornering. Third: many parts are cold and hard, and the lubrication is not enough, which leads to abnormal noise, and at the same time, the drive wheel can not be refueled violently when it slips, causing the planetary gear to bite on its shaft.

Fourth: the car is in the running-in period, the differential planetary gear and the half-shaft gear are not matched, and the abnormal sound occurs after a run-in period. Fifth:

It may be that the man-made operation is poor, resulting in improper coordination of car parts, resulting in abnormal noise.

The abnormal noise of the car driving at high speed is a manifestation of the car failure or a precursor to the failure. Therefore, once there is an abnormal noise, the car owner must check. It depends on what part of the body.

For example, if there is an abnormal sound in the body: first check whether there are objects in the trunk or rear seats of the car that are not fixed, easy to roll and make sounds, and exclude the noise caused by some items that are not fixed. If you find that the friction of the door and window parts of the car causes abnormal noise, you can put rubber strips on the doors and windows or pad rubber on the friction parts, etc., which may be able to reduce or eliminate the abnormal noise, but the result is only a symptom and not a cure.

If none of the above problems are found, then you must go to a regular repair shop for maintenance and troubleshooting.

Hello, it is recommended to check the interference of the components.

The car runs at low speed, there is no abnormal noise, running at high speed, there is an abnormal sound under the front of the car, what is going on, there should be a big throttle, so there is an abnormal sound under the front of the car, which is normal.

There is no abnormal sound when the car runs at low speed, and there is a layer under the front of the car when running at high speed, what should happen? Check what the reason is, it's best to go to the 4S store to have a look.

It is advisable to check the bearings of the steering knuckle.

When the motor is running at low speed, there is no abnormal sound, and there is abnormal sound when the speed is fast, which is caused by the formation of vortex due to the small surrounding space when rotating at high speed.
