Main purpose of this paper was to calculate and design a multi plate friction clutch while taking into consideration the working conditions of a heavy goods vehicle. At the start, a driving resistance had to be determined which the vehicle needs to overcome and based on the given results a selection of the appropriate engine was made. Furthermore, other components of drivetrain were chosen to establish parameters that act in the clutch. Then a calculation and selection were made of the clutch plates with needed friction surfaces to prevent too much heat accumulation on them. Next step demanded a calculation and control of one end of the output shaft to determine its dimensions, while withstanding the torsion that the clutch puts on it. Some derivatives of clutches often have a bearing on which the shaft lies, and same thing was made for this paper. A force was also calculated which the diaphragm spring can produce, because it is crucial that the clutch can transmit needed force on the rest of the powertrain. The construction of the clutch is also optimized with the help of software program Femap with purpose in mind to minimize its mass and retain the strength of structure. Finally, the technical documents are made containing arrangement drawing and manufacturing sheets which are given in the inset.
