Inspection and maintenance of automotive shock absorbers
The failure or damage of the shock absorber will directly affect the driving smoothness and riding comfort of the car, but also affect the service life of the auto parts. Therefore, the inspection and maintenance of shock absorbers is essential. When the car is driving 10-15 kilometers on the uneven road, touch the shock absorber shell with your hand, if there is no heat, it indicates that the shock absorber may have lost its damping effect due to lack of oil or damage to the main parts, and it should be removed for maintenance or replaced with new parts.
If there is abnormal continuous vibration during the driving of the car, the shock absorber should be carefully checked whether the oil leak, if the oil leak should be excluded. When performing secondary maintenance on the car, it is necessary to check the working condition of the shock absorber. The check method is: the lower end of the shock absorber is fixed on the vice, and the hand is stretched and compressed several times. The normal shock absorber should have a certain damping force, and the resistance to stretching should be greater than the resistance to compression. If it is unstable or has no resistance, it may be that the shock absorber lacks oil or the parts are damaged, and it should be repaired or replaced with new parts.
