The paper discusses friction phenomenon between the pushbelt (or chain) in the continuously variable transmission. This type of transmission is becoming more and more popular. It is so due to the technical progress last years and its indisputable advantage over conventional transmissions. It enables us to use the full characteristic of the engine. The introduction describes the issue, principles of the transmission’s operation, the construction of the steel pushbelt and a scheme of forces acting on a single belt’s steel element (segment). In the next part, the article explains the need of researches and their impact on the transmission’s proceeding. Moreover, a simplified model of the test bench with description of the proposed tests needed to elaborate sought relationships is included in the paper.
