The article presents an unconventional method for determining the reliability properties of friction clutches by applying a so-called certain random variable. The Dirac delta can be considered as the probability density function of this variable and used to describe failures/dysfunctions of a certain group of mechanical objects. For a typical automotive clutch mechanism, the following functional reliability characteristics were determined: – reliability function, – unreliability function, – probability density of failures. In machine design, during the construction and manufacturing process, there are often elements or sub-assemblies that have a precisely defined durability, i.e., whose correct functioning occurs over a single-valued, predetermined time. After this time, most often as a result of wear, these objects are no longer suitable for further correct functioning and must be replaced with new ones. (…)
