The paper presents the program and methodology of carrying out research on kinematic pair with pivoting friction. There was examined a node with pivoting friction in bearing concentrated connection flat surface-spherical bowl. During the research there were determined two types of characteristics – characteristic of friction moment as a function of load and experimentally designated characteristic of wear of the frictional kinematic pair. Both of the assigned characteristics are compared.

Internal combustion (IC) engines are main source of power used in the automotive industry. These engines have undergone many up gradation for decades, with an initial goal of increase in power of the unit. Presently, as a result of tightening environmental regulations, research is focused on reducing harmful gases emissions along with increase of the engines efficiency.

The paper shows problems and examples finishes solutions applied in the motor industry which be used by solar car production to competition World Solar Challenge. The subject matter will contains the mechanical matters connected with endurance of materials, the wheel set and aerodynamics as well as the electric questions relating the photovoltaic and conversion of electric energy on mechanical energy.
