Embodiment Construction
[0016] According to the present invention, the vibration absorber for reducing the vibration of a structural component includes a vibration-absorbing mass block and two elastic elements, and the two elastic elements are respectively arranged at both ends of the vibration-absorbing mass block for elastically coupling the vibration-absorbing mass block to the structural component. The two elastic elements each comprise a tubular section of elastic material extending in a direction away from the shock-absorbing mass up to a fixed profile at its outer circumference for positioning and arrangement on the structure into the opening of the hardware mounting base. A pin-shaped limiting structure is provided in each of the two tubular sections. Two limiting structures limit the deflection amplitude of the vibration-absorbing mass relative to the structure. According to the invention, two tubular sections made of elastic material are tightly coupled with the shock-absorbing mass, and t...

The invention discloses a vibration absorber (2) for reducing vibration of a structural part. The vibration absorber (2) comprises a rigid solid (13) providing a vibration absorbing mass block (10) and two elastic elements (11) for elastically coupling the vibration absorbing mass block (10) to the structural part. The elastic elements are arranged at two opposite ends of the vibration absorbing mass block (10), each of the two elastic elements (11) comprises a tubular section (15) made of an elastic material (12), and the tubular sections are closely connected to the rigid solid (13) and extend to fixing outlines (16) on outer circumferences in the direction away from the rigid solid (13). Each fixing outline (16) is used for positioning and is arranged in an opening (8) of a mounting base of the structural part. A pin-shaped amplitude limiting structure (20) arranged in an inner cavity of each tubular section (15) belongs to a part of the rigid solid (13) and can limit deflection amplitude of the vibration absorbing mass block (10) relative to the structural part.
Description
technical field [0001] The invention relates to a vibration absorber for reducing the vibration of a structural part, the vibration absorber comprises a vibration-absorbing mass block and two elastic elements arranged at opposite ends of the vibration-absorbing mass block, and the two elastic elements are configured to hold the vibration-absorbing mass The block is coupled to the mounting bracket. Further, the present invention relates to a vibration absorbing device comprising the above vibration absorber. Background technique [0002] Vibration absorbers can be used to reduce the vibration of different structural parts. Many vibration absorbers are found in motor vehicles. Here, for example, the vibration absorber can reduce the vibration of the door body and the cover body. These vibrations have a relatively low frequency, for example less than 100 Hz. In order to tune the vibration absorber to such a low vibration frequency, the physical mass of the vibration-absorbi...
