Abstract: A damper system for damping vibrations of an assembly unit of a vehicle comprises one or more main vibration dampers and one or more acoustic bushings. The respective main vibration damper is tuned to vibrations from a lower frequency range. The respective acoustic bushing is tuned to vibrations from a higher frequency range which lies above and does not overlap with the lower frequency range.

Abstract: A vibration damper is disclosed which comprises a base portion for fixing to a vibration source. At least one spring portion is provided which is held on the base portion via at least one bracket. A damper mass is provided for absorbing vibration energy from the vibration source, and which has at least one continuous opening through which the spring portion extends.

Abstract: A vibration absorber for absorbing a vibration of a vibrating component is provided and includes: a spring system and an absorber mass arranged on the spring system. The spring system includes: a first spring element with a first core, and a second spring element with a second core. The first spring element is arranged on the second spring element such that the second core borders the first core, and the vibration absorber can be fastened using a fixing element to the vibrating component in which the vibration is to be absorbed. Furthermore, a method of producing the vibration absorber is further provided.

Abstract: An oscillation damper is provided and includes: a holder for mounting the oscillation damper on an object to be damped; a damping mass; and a coupling device designed to mount the damping mass on the holder. The coupling device includes: a damping mass mounting element rigidly connectable to the damping mass; a holder mounting element rigidly connectable to the holder; and a spring element resiliently mechanically coupling the damping mass mounting element to the holder mounting element. A method for manufacturing an oscillation damper is further provided.

Abstract: A vibration absorber (1) with radially acting hydraulic damping has a bearing core (2). A bearing cage (4) radially surrounding the bearing core (2) and an elastomer body (18) resiliently connects the bearing core (2) and the bearing cage (4). An outer sleeve (24) radially surrounds the elastomer body (18) for connection to an absorber mass (40). At least two working chambers (28) to be filled with a damping fluid are formed in the elastomer body (18). The working chambers (28) are connected fluidically to one another by means of a dimensionally stable fluid duct (26).
