Abstract The invention relates to a device for indicating the condition of shock absorbers of wheeled vehicles. According to the in- vention, an accelerometer (G) is attached on the spring susp- ension (U) of the wheel (H) in question and capable upon pass- ing of the vehicle over road irregularities to emit a decaying A.C. signal (S) with information on the oscillations of the axle (A) and the damping of the tyre. After integration in an integrator (I) the signal is a measure of the difference betw- een the damping of the shock absorber at expansion and at com- pression. This signal is compared in a comparator (K) with a reference signal (Vref) for the permissible damping difference and results in alarm (L) upon achieving said difference.
