According to the detachable dynamic vibration absorber provided by the utility model, the elastic body (3) can be detached conveniently from the mass block (1) and the connecting plate (2), and the detachable dynamic vibration absorber has the characteristics of conveniences for debugging, high interchangeability, low cost, wide application range and the like.
Description
Technical field
The utility model belongs to passive vibration damping equipment fields such as vehicle steering wheel or seat, particularly a kind of novel detachable dynamic absorber apparatus.
Background technique
The frequency modulation type dynamic vibration absorber is widely used in the passive vibration damping of automobile field, like steering wheel, outlet pipe and seat vibration control etc.The frequency modulation type dynamic vibration absorber is generally controlled through the vibration peak frequency domain to the principal oscillation system, is about to the original single vibration peak of principal oscillation system and is reduced to two vibration peak that amplitude is less, thereby reach the purpose of the vibration amplitude that reduces the principal oscillation system.The theory structure of frequency modulation type dynamic vibration absorber is as shown in Figure 1, i.e. the quality spring-damp system of single-degree-of-freedom, and quality, rigidity and damping characteristic through the rational Match dynamic vibration absorber can be optimized design to the principal oscillation system.
The modal dynamic vibration absorber of automotive field is to form through rubber and mass block sulfuration, in case the weight of elastomer kind and mass block confirms that then the debugging frequency of bump leveller can be confirmed, so the debugging of the natural frequency of its bump leveller is difficult relatively.And when automobile vibration is controlled; Often need the bump leveller of different frequency and different quality piece to be used for vibration control, this moment, conventional metal-rubber integrated vulcanizing method was used for vibration controls such as vehicle steering wheel, tables and chairs owing to above-mentioned shortcoming is not suitable for dynamic vibration absorber.
Summary of the invention
The utility model technical problem to be solved provides a kind of novel detachable dynamic vibration absorber, to solve the existing deficiency of common metal rubber integrated vulcanizing formula dynamic vibration absorber.
The utility model solves the technological scheme that its technical problem adopted: a kind of novel detachable dynamic vibration absorber is provided; Form with connecting plate 2 by mass block 1, elastomer 3; It is characterized in that: have the aperture 4 of some and the narrow end 33 of elastomer 3 to assemble on the described mass block 1 through teeth groove I31 and flange I21; Have the aperture 4 of some to assemble through teeth groove II32 and flange II22 with the wide end 34 of elastomer 3 on the described connecting plate 2, described connecting plate 2 is connected with the principal oscillation system through bolt or welding manner.
The aperture 4 of some and shape is set on the described mass block 1, and wherein aperture 4 is provided with flange I21 and cavity 35.
Said connecting plate 2 is provided with the flange II22 of some, and connecting plate 2 is connected with the principal oscillation system through bolt or welding manner.
Described elastomer 3 is assembled with mass block 1 and connecting plate 2 respectively by narrow end 33 and wide end 34; On the narrow end 33 teeth groove I31 is set; On the wide end 34 teeth groove II32 is set, the variable cross section of elastomer 3 zone 36 bump leveller more is axially different with radial rigidity and debug.
Described mass block 1 is processed by cast iron or alloy, and described connecting plate 2 is processed by panel beating, and described elastomer 3 is processed by rubber or polymer.
Beneficial effect
The utility model can conveniently be applied to passive vibration controls such as vehicle steering wheel, seat and outlet pipe, and its clear superiority is: (1) elastomer rigidity is lower, especially is fit to low frequency vibration damping; (2) the axial and radially decoupling zero of bump leveller helps the product performance debugging; (3) for convenience detach, can match the bump leveller of broad frequency; (4) reasonable integral structure, simple and practical; (5) metal and rubber need not integrated vulcanizing, and cost is low.
