Wet disk clutches are important components in modern drivetrains and have both comfort and safety-related tasks for the powertrain. The underlying tribological system, consisting of friction pairing, lubricant, and loads, is of central importance for the function of the wet disk clutch. The choice of a specific tribological system significantly influences the friction behavior. Comfort and safety of the clutch can be characterized by the friction behavior at low sliding speeds, in the so-called low speed slip. For good controllability of the clutch, an increase of the coefficient of friction over the sliding speed is of central interest. In addition, the determination of the static friction coefficient is also of particular importance. Previous studies have mainly focused on the influences of friction linings, lubricants, and loads on friction behavior. In the projects FVA 343/III and /IV, the influences of the steel plate properties on the running-in behavior were investigated. In addition to significant influences of the steel plate properties on the running-in behavior, significant influences on the friction behavior of the run-in clutch were also shown. Currently, there are no transferable, systematic findings on the influences of steel plate properties on the friction behavior of run-in clutches in slow speed and micro slip. In the project, the influences of the steel plate properties on the friction behavior in slow speed and micro slip will be identified based on experimental investigations and correlated with characteristic areal friction coefficient values based on surface characteristics. Such a correlation enables targeted optimization of the manufacturing parameters and final machining steps in steel plate production with the aims of reducing manufacturing costs and optimizing the performance of the clutch.
