The tribology of the car: Research methodology and evaluation criteria

From a position of structural and power theory of friction and wear, it is possible to apply the method of Contact Electrical Resistance (CER) for a complex research of the processes in a-zone of frictional contact. The purpose of this paper is to present a construction of friction node and drive mechanism of friction machine. As a result of the reported study the regularities of changes the CER and tribomechanical indices for non-metal friction couples in dependence on loading parameters and lubricating media were received. Also, the method of determination the range and level of normal wear and critical points of transmission to damage in accordance with kinetics of wear changes is proposed. The interrelation between geometrical, physical and mechanical properties, processes of formation, transformation and destruction of secondary structures, tribotechnical indices and CER in dependence on operation regimes of friction couples
