Rail vehicle with at least one elastically deformable component and method for determining the onset of a wear-related component remaining service life on a rail vehicle

摘要

The invention relates to a rail vehicle with at least one elastically deformable component as a structural part and / or bearing part, which act in the course of operation of changing driving conditions dependent, different deformation forces, which lead to a component service life limiting component wear. According to the invention, a time-repeating, respectively identical driving state is predetermined, to which a specific, respectively identical deformation force is assigned. Upon detection of such a predetermined driving state (2), a measuring operation is automatically started by a start signal and carried out (3), wherein a component deformation is measured as a parameter for a current component stiffness. Then, a comparison is made of a current deformation measurement value with respect to previous stored deformation measurement values (9), with the result that the deformation measurement values stored over a relatively long service life, or the component stiffness in a low inclination plateau region (17), are approximately the same secure component function is detected, or that alternatively over a short period of use successively detected deformation measured values are successively and progressively larger, whereby the beginning of a wear-dependent predetermined component remaining service life determined and a corresponding warning information is output (12).
