IMPROVING THE SPINNING OPERATION OF VARIOUS CLUTCH RELEASE BEARINGS USED IN THE CLUTCH SYSTEMS OF HEAVY COMMERCIAL VEHICLES WITH A NEW SPINNING GEOMETRY

OĞUZ CAN BARGUN, ANIL ÇELİK, ÜMİT OKAN YAZICI, A. MERDAN

In this study, how the geometry change in spinning operation of clutch release bearing which used in various heavy commercial vehicles effects its tensile strength was investigated numerically and experimentally.

Old spinning geometry caused a loosen problem of the release bearing cover due to constructive constraints. In order to solve this problem first, a three-dimensional solid model of the clutch release bearing was created using the 8.0 version of SIEMENS NX software. Subsequently, structural analysis of the created solid model was completed with the Static Structural module of the 17.0 version of the ANSYS Workbench simulation software. As a result of the data obtained after analysis, a new spinning geometry is designed considering constructive constraints of the spinning workbench. Five prototypes were manufactured in order to verify numerically obtained data experimentally. Tensile tests have been performed on these prototypes. The three-dimensional modeling and structural analysis data of the clutch release bearing led to determine deformation limits and tensile strength of the bearing system. 

In conclusion, thanks to the new spinning geometry, the desired axial tensile strength of the clutch bearing has increased about 40 percent compared to the old geometry.
