Drive pinion pref. to drive camshaft of IC engines has elastically deformable spokes engaging on counter bodies, to dampen power peaks

摘要

The force between a hub (1) and the meshing area of a traction device on the front face of a drive pulley (6), is transmitted by radially deformable spokes (3). With increasing relative twisting angle between hub and meshing area, the spokes are supported on counter parts (4), which are fastened non-turnable to the hub. The spokes and/or the support profile (5) on the counter parts, is/are formed so that the momentum acting against the twisting motion increases with increasing twisting angle.
