Friction clutches are mechanisms placed between the engine and the gearbox and are used to transmit the torque from the engine of the vehicle to the transmission. The clutches should provide start and stopping of the vehicle without vibration and need to have a certain lifetime. The tribological parameters of the linings in these clutches depend on several factors: the quality of the linings, the conditions of the test (exploitation), the temperature between the friction surfaces, the specific pressure between the friction surfaces, the speed of sliding of the friction linings, the number of turns on the clutch, etc. In this paper, will be analyzed the impact of the speed of sliding of friction linings on the tribological parameters of the linings.
