[introduction]
As the addition of use time, chassis spare parts because jolt, ford, hard to avoid can arise wear away clearance, bring abnormal knocking thereby. And common to us chassis abnormal knocking, believe a lot of people can have encountered this kind! When bumpy and successive pothole, front-wheel drive appears " " aggravating sound. What be after all cause? How are we handled again? Hand of handgrip of old today driver teachs you.
30 seconds fast read content of full text key:
1, maintain with the choice of makings, had better use ball basket oil. High temperature resistant performance is better.
2, processing environment should seek the ground clean and a sector of an area of level off hale and hearty.
3, head of ball of stable lever connecting rod also can produce this kind of abnormal knocking, want to notice to differentiate.
4, after maintenance ends, want trample a few times footplate of apply the brake.
One, breakdown phenomenon
1, car is slow fast travel arrives successive pothole road surface, discover front-wheel drive appears " " abnormal knocking.
2, jockey condition, we kick a wheel with the foot, can discover abnormal knocking appears.
3, caliper of rock apply the brake, can discover its activity amount is larger.
2, the judgement process of breakdown
1, above all we are after affirmatory good abnormal knocking, want to eliminate the abnormal knocking that place of chassis spare parts produces first.
2, after tearing open discharge wheel, we want a platoon to check decrease brace up whether to leak oily, change ball of arm of head of pull rod ball, lap to the head whether loose free from worries.
3, part of activity of caliper of rock apply the brake, can produce abnormal knocking and existence clearance, can judge for caliper abnormal knocking.
4, means of settlement, wear away badly change oriented annul, grease of not serious daub.
3, of caliper of apply the brake disassemble
1, of jack prop up
Prop up to jack, elaborated more nevertheless. We should make sure the the earth's surface is solid level off, do not be in uneven or earth the earth's surface props up car.
2, the examination of braking system all
After tearing open discharge wheel, we can see, apply the brake dish the surface and intake exist have many rustily case, this showed this car wheel often is put in the circumstance such as ford, cause apply the brake dish place appears serious and rustily. Evermore also will be brought about oriented annul into aquatic rust.
3, oriented those who sell disassemble
Of every model oriented annul disassemble somewhat difference, but basic it is very much the same. We are used inside spanner of 6 horn bolt will be oriented annul tear open debus to come according to anticlockwise direction can.
4, oriented those who sell maintain
Disassemble oriented after selling, we can see oriented annul what had lost grease is lubricant, the surface has been put in slight wear out condition. Because do not have grease to undertake inside installing hole,decrease brace up, bring about Qian Songkuang of apply the brake to appear thereby abnormal knocking. We sell positional daub grease to directing, can solve abnormal knocking problem.
5, the examination of head of ball of stable lever connecting rod
Stabilize clearance of existence of head of ball of lever connecting rod with shock absorber connective, also can bring about same abnormal knocking to happen. After so we tear open discharge wheel, also want to undertake checking to head of ball of this connecting rod, if appear clearance, need changes.
6, maintain need to notice
After handling caliper of apply the brake, we are before car travel, want successive trample a few times footplate of apply the brake, let caliper of already loose apply the brake, return working place again, apply the brake of the first foot in avoiding travel is out of order, create risk. This is a very crucial step.
4, how to avoid abnormal knocking of caliper of apply the brake
1, avoid often ford is too deep.
2, every other 20 thousand kilometer, disassemble oriented annul undertake lubricant cleanness to its.
Write finally:
Chassis abnormal knocking is we raise the common little trouble in the car. But how to avoid little trouble to be maintained greatly by maintenance shop, with respect to need then ourselves has a capacity that judges breakdown. Believe to adopt afore-mentioned measure, we can direct because of apply the brake certainly annul wear away the abnormal knocking that bring about. Him likelihood can make decided issue 5 minutes, go maintaining bit of flower to treat unjustly money why? Did you learn?
