摘要

The device has a closed housing (1) which surrounds a vibration damper ring (2). A surface warm is discharged to surrounding air over the closed housing. A knurl is attached at a front side (5) and is arranged outward radially from an inner diameter without interruption. The knurl is attached at a housing front side (51) and a cover side (52). Radial characteristics of the knurl are interrupted by a circular surface. The knurl exhibits a depth of 0.5 millimeter.
