car abnormal noise as a problem that many consumers have a headache, not only has a very big impact on the car’s driving comfort and texture, and will give motorists one kind of misjudgment in the car manipulation, abnormal sound car wide range of sources, a variety of reasons, many consumers believe that just because a vehicle abnormal sound of normal aging, and occasionally take some of the bad roads appear abnormal sound but did not occur under normal circumstances, so many consumers will I did not care, but it is for our whole buy publicity hidden between such casual, then what is abnormal sound car will not affect our traffic safety, and we in turn how to prevent and improve these abnormal sound.
Suspension aging of rubber parts
Suspension rubber bush on aging is the main source of the suspension portion of the abnormal sound, but also on the main highway cars of one of abnormal sound sources, many consumers do not care about the suspension bushing of abnormal noise caused by aging, that this is normal, and even some professional third-party repair agency will not take too seriously aging bush . First, abnormal noise caused by the suspension bush bush Chengdu will increase as aging aggravation frequent, and the pressure at the end bushes stage of aging, consumers need to be replaced but did not replace, the abnormal sound will evolve into road safety problem.
Our most common suspension bush portion of the rear suspension from the general, because the suspension load is relatively high, the frequency of the vibration is large, the liner accelerated aging site , rubber elasticity decrease after aging the suspension and reduce the buffer roll bars, will issue directions with control instability, and the like hair floating chassis. General replacement of rubber bushings require professional bodies, using special equipment to replace some strong hands of consumers will choose their own forum on replacement, but requires the use of rubber bushing press to install their own replacement and can not achieve the desired effect using .
modification of the suspension fitting
The suspension of the chassis with the deformable member is one of the main sources of the chassis does not affect the deformation of the fitting because of the general underpinning caused, although some sites equipped vehicle armor, but also cause slight deformation at the time of fitting the underpinning, the suspension member as a precision high precision cars, although a slight change is sufficient to cause the steering system Some subtle changes so that the belt turnAbnormal sound heard when the chassis.
Sometimes excessive shock to the suspension, the suspension can also cause a slight deformation of the fitting member, and a direction back to the positive influence not only the steering wheel is too deceleration zone, it is one of the reasons causing abnormal noise! For maintenance of the chassis fitting, using the wheel alignment may be slightly corrected, and when necessary to replace the severely suspension assembly.
is less than the deformation strength of the vehicle body
First of all, the modern vehicle is assembled and soldered together, so that some parts of the weld gap is present, when the vehicle is not driving on road conditions when on a good road, most of the monocoque suspension because the forces transmitted to the body in some circumstances cause a slight deformation will be relatively large body, first of all it is deformed because of insufficient stiffness of the body caused most of the design who will use this buffer gap welding deformation, but the deformation will cause a certain degree of abnormal sound, long-term travel in the past, bad road conditions on the road, the suspension will cause deformation in turn causes the body narrow gap welding.
To solve the abnormal sound because body deformation caused by welding the slot, the most traditional method is to use a buffer or sealant, for Tiantu gap in the vehicle body, and periodically replaced to prevent deterioration of the rubber elasticity decreases. Cause
Engine Knock immediately repair
For the generation of abnormal noise of the engine parts, because more diverse, but the most important, because the piston caused by the movement of the cylinder, the cylinder piston to be in abnormal shocks Games cylinder, resulting in a lot of abnormal sound. Many car owners in low-knowledge, and the engine does not produce abnormal sound, but at a high speed and high speed conditions, it will produce a lot of abnormal sound, the engine block is generally the case appeared abnormal, preferably as soon as possible treatment, to prevent permanent damage occurs to pull the engine cylinders.
engine knock is the most direct factor leading to the lubrication system, oil is not replaced or use low-grade oil, can cause engine knock. Moreover, engine deposits is one of the causes of engine knock, adding the appropriate fuel additive, reduce carbon deposition, abnormal sound of the engine can be reduced to some extent.
interior materials and assembly errors
abnormal noise caused by the interior is a lot of car owners will encounter, though it does not affect us in a way of driving security, but to use our car comfort greatly reduced. Interior cause of abnormal sound of two main, first of all because of the relatively large interior assembly error, in the assembly had already caused some distortion to cover the interior, so that these errors will occur when the body slight deformation resulting in contact with each other between the cover caused by abnormal sound, after a long time, it can cause serious distortion interior cushions aging. Second reason is because now most of the low-end models of the interior which is made mainly of plastic, although the cost savings, but extremely easy deformation of abnormal sound.
automotive interior of abnormal noise is indeed plagued many owners, be modified to upgrade automotive interior and exterior, the interior can be reduced to some extent on these, but to reduce these impacts fundamentally, many manufacturers also need designers to optimize and improve the assembly accuracy.
