Reduction of costs related to automobile operation due to increase of their systems resource is the actual scientific and technical task that can be done in various ways. One of the ways is to use automatics which provide optimal operating modes. It is known that clutch friction pairs of self-propelled machines are less durable components of transmissions therefore above mentioned ideas are especially relevant for them. The disk friction clutch is a system whose state changes during operation due to wear disk pads. Considering it as one of the objects of automatic control of stepped mechanical transmission, it should be mentioned that the change in its state entails a change in the characteristics of work processes flow. If there is no means to address this change or to track and compensate it in automatic control system the algorithm used by system will gradually lose the adequacy to object, which will result the accelerated wear of pads and increase of costs related with both disc replacement and downtime of automobiles during repairs. The presence of clutch elements that have non-linear elastic characteristics in the design allows to assume that this process will have a non-trivial nature requiring to study regularities that in the future will assess their impact on the loading of friction pairs. In this paper, the construction and implementation of appropriate mathematical model solves first of these tasks in relation to the friction of single-disc dry clutch, where pressure is created by the split diaphragm spring with a direct installation.
