Rotational speed-adaptive vibration damper for motor vehicle, has shell arranged and pressed into recess, where shell is formed in path for damper mass that is formed as roller body, and damper body designed as belt pulley or chain pulley

摘要

The damper (1) has a damper body pivotable around an axis of rotation, and a damper mass (7) adapted to an excitation frequency, where the damper mass is movably accommodated in a recess of the damper body. A shell (6) is arranged in the recess, where the shell is formed in a path for the damper mass. The shell is pressed into the recess. The damper mass is formed as a roller body, and the damper body is designed as a belt pulley or chain pulley (2). The damper body is sintered or manufactured from aluminum-die casting or plastic or from non-cutting steel.
