4.2.5. Check of shock-absorbers on амортизаторном the stand
On амортизаторном the stand shock-absorbers can be checked up without their removal from the car. Amortizirujushchee action is estimated on the basis of an arrow or expression deviation.
Temperature 10–40 °C.
The driver is in the car.
Pressure in tyres should be in norm
To drive on the stand it is necessary so that wheels have risen directly and on the centre of platforms for wheels.
Result forward wheels in position for movement directly.
It is not necessary to tighten a manual brake, a foot brake do not press.
Amortizirujushchee action can be sufficient or insufficient
Intermediate values at lowered амортизирующем action are not defined.
Предсказывание remaining working life it is not supposed.
The measured values deduced at operation of a spring to a release, are incorrect.
|Fig. 4.37. The check scheme амортизирующего actions
Following values concern only the stands listed above. Excess of the specified values means that action of shock-absorbers is weakened so that their replacement (fig. 4.37
) is recommended
Boundary value = 70.
«a» = it is more 70: амортизирующее action is not enough.
«a» = it is less 70: амортизирующее action is enough.
That, какакая the combination damperов is established on the car, is specified by corresponding number PR on the information tablet of the car.
Boundary values "an" are given in mm.
If the shown value more boundary «a» (tabular value), амортизирующее action is insufficient – it is necessary to replace the shock-absorber.
If the shown value less boundary «a» (tabular value), амортизирующее action is enough – it is not necessary to replace the shock-absorber.
