Abstract
In contemporary vehicles, friction clutches are exposed to increased engine performances, i.e. increased torque,
particularly for vehicles equipped with diesel engines. Demands for low mass and low moments of inertia of the moving
parts are more pronounced. Towards the aim of meeting those demands, there is a tendency for manufacturing of clutch
covers by drawing from a thin tin sheet metal, thus decreasing their axial stiffness, and increasing the path of the release
bearing. Such a situation in conditions of increasing vehicle speed endangers the fast and precise work and functionality of
the friction clutch. Concomitantly, the effort and the work that the driver needs to make and do during its clutch release
increase. These factors need to be within certain limits.
This paper provides an analysis of a possible response to this kind of challenges. The focus is pertinent to the
analytical and experimental analysis of the capacity to decrease backlash in the process of release of the clutch with an
inexpensive technological procedure for profiling the fingers of the diaphragm-spring as a way to increase their stiffness.
The impact of the analyzed interventions on the dynamic durability of the diaphragm-spring is also assessed through an
adequate experiment.
