| 摘要： | Airbags are usually given pretty cursory attention during a normal maintenance cycle, according to Owen Jenkins, engineering manager at component manufacturer BPW, one of the biggest suppliers of air suspension systems. However, he adds: "Fundamentally there isn't any [particular] thing that goes wrong with them, because over the years firms have designed [problems] out - anything that evolves or develops through generational changes becomes far more reliable." Airbags must be checked at every statutory inspection, looking for leaks, visible damage and perishing: one of the anti-ageing compounds used in rubber was removed due to changing legislation some years ago, so "perishing does now become more evident sooner," says Jenkins. "Any sign of external damage is going to cause problems, and any sign of perishing, particularly where the rubber folds or rolls under." An airbag, he adds, "is a pretty robust bit of rubber, but keep an eye on those joins and folds". The piston itself should be inspected and the shock absorbers checked for leaks or damage. If they are defective, the airbags could be overly stretched or squashed on to their bump stops. |
