Abstract: An effective reduction of vibration overshoots is intended to be effected in a drive shaft, which is configured as a hollow shaft (8), with simple means at the particular vibration maximum (vibration antinode). A vibration absorber (2) is arranged within the hollow shaft (8) and includes a damping mass (absorber mass) (4) and an elastic coupling element (6). The absorber mass (4) is operatively connected to the inner wall of the hollow drive shaft (8) via the elastic coupling (6). The absorber mass is configured to be rotationally symmetrical and axially symmetrical and has, at its center, a constriction (12) for accommodating the elastic coupling element (6). For use as a drive shaft (hollow shaft) (8), which is built in in the vehicle transverse direction, and for use as a drive shaft (8) (cardanic shaft configured as hollow shaft) which is built in in the vehicle longitudinal direction.

Abstract: A bellows for encasing the connecting region of a tie bar of a motor vehicle is provided. The inner surface of the mounting collar is provided with projections that extend at an oblique angle to the axis of the mounting collar. Free spaces that remain next to and between the projections can be filled with a lubricant.

Abstract: A vibration damper comprises an attachment member and a damping mass connected by an elastomer spring with a plurality of elastic coupling elements. The coupling elements are inclined relative to the direction of the spacing between the damping mass and the attachment member. The inclination angle of the coupling elements is adjusted so that the natural vibrational frequency of the vibration damper in the spacing direction can be tuned largely independently from that in a direction perpendicular to the spacing direction.
