In this paper it has been presented a research stand that allows to measure static and dynamic friction parameters between the belt and the pulley in a belt transmission. The stand can be rebuilt to three configurations to measure: static friction, the so-called kinetic and dynamic friction characteristics as well as complete belt transmission. It can measure friction parameters of any belts transmissions occurring in cars: flat belts, V-belts or poly-V belts, except toothed belts. In the stand there are build-in torque and force sensors – to measure engine torque and tension of the belt, and rotation and displacement sensors measuring angular velocities of the pulleys and displacement of the slack part of the belt. Finally, some sample results of poly-V belt 5pk, achieved from the research stand are presented.
