The friction inside the automobile mechanical transmissions leads to a large influence of the classic fuel consumption and also to the environment impact. Actually, the chain drive is one of the most important transmission inside a car and has few friction sources inside, as the properly chain friction between its components (links, pins), the friction between the chain links and the sprockets and also the friction between the chain links and the tensioning guide active part. The paper main objective is to study the friction phenomenon in the chain link – pin contact for different loads. The tests are achieved for different sets of motion rotational speeds and normal loads; so according to these, there are determined the dynamic friction coefficient (during the motion) and the static friction coefficient (at the stroke ends). The results led to the static and dynamic friction coefficient variation, with the motion rotational speed and the normal loading force. In the final part, the conclusions are presented.
