METHOD FOR OBTAINING WEAR CHARACTERISTICS OF RUBBER BUFFERS AND RUBBER BUFFERS FOR VEHICLES
The invention relates to a method for obtaining wear characteristics of rubber buffers and to a rubber buffer construction, the method comprising the following steps: step 1: fitting the vehicle with rubber buffers, each rubber buffer having the following features: a rubber block (1) having a lower and an upper cover plate (2a, 2b), wherein at least one pressure-measuring cell (3) is fastened in at least one of the cover plates (2a, 2b) in such a manner that the pressure-sensing surface (3a) thereof and the inner surface of the cover plate (2a, 2b) lie in the same plane (2aE or 2bE), provision of a data-acquisition and data-storage device for acquiring and storing the measurement signals generated by the pressure-measuring cells and provision of a signalling device for emitting a malfunction signal; step 2: establishing and storing a calibration signal pattern of the new rubber buffers and defining a malfunction criterion; step 3: acquiring and storing current signal patterns; step 4: comparing the current signal patterns with the calibration signal patterns and determining whether the current signal patterns contain inadmissible abnormalities.
