If the interior of the tire in travel process gives out the sound that the metal collides, because avoid,the likelihood is shake implement damaged with bearing, should go maintenance of 4S inn examination just can be solved.
Automobile body abnormal knocking
Driving in the process, especially slam the brakes on and when quickening, the certain place of automobile body can have a few abnormal knocking, although not very affects safety of drive a vehicle, but the car that makes a person special worry about his can malfunction. The abnormal knocking that these automobile body give out, the constitution with car itself is actually relative, because stiffness is insufficient,some likelihoods are and in bringing about car travel, happened to be out of shape, the sound that for instance door and car casing chafe or shake and gives out, of course some places are sealing off also can cause the clash between armor plate. The part between general automobile body is fixed and bad to also can produce abnormal knocking, such circumstance wants to go up only close screw is OK.

Pensile abnormal knocking
Pensile abnormal knocking passes decelerate to take in car commonly or be rough entire road surface when very serious, pensile abnormal knocking is not 9 can say, we just also are analysed simply. Pensile abnormal knocking works to wait to matter circularly with engine rotate speed, bear, temperature, engine. Pensile component and taken a surname are concerned moderately, still concern with safety of drive a vehicle, must want bring to sb's attention so. If encounter,give out near 4 wheel when jolt " Ca of Dong Dong, Ka " sound, because,be likely shock absorber problem or it is pensile component becomes loose cause.
Gear-box abnormal knocking
Car has in interior of the gear-box in travel process " rustle " sound, and step on next clutch or be did not have again after accelerator, the meeting when shift gears has similar whistled sound. If the place that noise origin is gear-box is encountered in travel, it is gear-box likely so bearing or it is gear wears away, bearing stain brings about. If carry the gear-box when fast shift gears to produce abnormal knocking, may be gear-box so metallic powder is contained among oil, meet namely the component of the and so on of brake band clutch among place gear-box is excessive wore away. Gear-box belongs to accurate equipment, so occurrence abnormal knocking needs to be maintained in time.
Steering wheel abnormal knocking
Because change head of ball of horizontal pull rod to ageing,steering wheel abnormal knocking basically is, need changes; Also may be directional machine dustproof the oil that cover leakage, the attrition voice that create; If hit,heard when direction " click clicks " abnormal knocking, this specification changes direction machine have a problem, need changes; If be degree of tightness of brunt leather belt,spend undeserved or be ageing, also can have abnormal knocking.
Engine abnormal knocking
If because shake the sound that give out,be transmitter,that is normal phenomenon, need not worry. But if engine gives out the cry of leather belt howl that incline the head, that is caused. If engine carries the metal is given out when turning the bleep of dry attrition, because,be dynamo, water pump, change bearing of the pump that help strength to attaint. If start machine movement to have flat voice, the likelihood is exhaust system jams, vacuum tube leak or be to rupture. Once engine produces such abnormal knocking, it is big trouble commonly, need sends the overhaul.
Car can give out certain noise more or less in travel process, loud voice of rotate speed of the engine on high speed is for instance bigger also, fetal a confusion of voices is bigger also.
