Process of detecting absolute limit of wear of a pneumatic

摘要

1 / 1 Summary "detection process unified, the limit of wear of a tyre" the detection process of wear applies to a tyre (10) comprises NIS 5 set (s) of tread wear indicators sound associated with at least two wear limits (S1, S2, S3, S4, S5, S6) In order to generate acoustic noise of printing at least above each threshold (S1, S2, S3, S4, S5, S6).Each indicator of each set is substantially aligned axially with each other indicator in the set. For each threshold S1, Kmin is the minimum value of the Ki values for I. [2], m where m is the number of 10 total limits: ki = NIS / NIS - 1 when the value of I. 6 [2, M], NIS / Nemi - 1 1 or ki = Nei - 1 / NIS when the value of I. [2], M 1 / NIS, NIS - 1.For each threshold S1 is detected the noise of acoustic printing speed v. is limited to the value of the speed V to an interval I =] Vmin; Vmax] check Vmax kmin.vmin.
