Abstract
A dynamic shock absorber comprises a mass block, a base, a rubber block and a hoop, wherein the mass block and the base are fixed to the two ends of the rubber block respectively; and the hoop comprises an arc elastic hoop piece, connecting lugs are fixed to the two ends of the elastic hoop piece, the hoop is fixed to the outer surface of the rubber block, and the two connecting lugs are connected through a bolt structure. The dynamic shock absorber has the beneficial effects that the frequency of the dynamic vibration absorber can be adjusted continuously for the type test work of the dynamic vibration absorber, so that the frequency of the dynamic vibration absorber is determined quickly and accurately, and adaptability of the dynamic vibration absorber is also improved, that is, the same dynamic vibration absorber can be used for different automobile parts by adjusting the frequency. The dynamic vibration absorber further has the beneficial effects of being simple in structure and convenient to use.
Description
Technical field
The present invention relates to a kind of auto parts and components, especially relate to a kind of dynamic vibration absorber.
Background technique
Dynamic vibration absorber is a kind of vitals of automobile, generally includes base, block rubber and mass block, and the two ends of block rubber are connected with base and mass block respectively.Dynamic vibration absorber usually by floor installation on the auto parts and components such as vehicle frame, chassis, be used for reducing corresponding vibration, in the hope of the resonant belt of attenuating structure noise to greatest extent, improve vehicle travel in sound quality.
Application publication number CN102121506A, name is called that the patent application document of " a kind of frequency-adjustable bump leveller be arranged on automobile suspension rack " discloses a kind of dynamic vibration absorber: " comprising base, block rubber and fixed mass block ", " it is characterized in that: described fixed mass block carries threaded stem; at least two pieces of variable-quality blocks are housed on described threaded stem, tighten fixing described variable-quality block in threaded stem upper end by nut." shortcoming of this patent is: complex structure, can not the frequency of continuous setup bump leveller.
Summary of the invention
Main inventive object of the present invention be to provide a kind of structure simple, easy to use, can the dynamic vibration absorber of frequency of continuous setup bump leveller.
The present invention's technological scheme used is: a kind of dynamic vibration absorber, comprises mass block, base, block rubber and clip; Mass block and base are separately fixed at the two ends of block rubber, and described clip comprises the flexible collar sheet of arc, and the two ends of flexible collar sheet are fixed with engaging lug, and described clip is fixed on the outer surface of block rubber, and two engaging lug bolt arrangements are connected.
During use, first utilize the flexible fastening of flexible collar sheet on the outer surface of block rubber clip, the apparent surface of two panels engaging lug has certain gap, distance between the apparent surface that just can be adjusted two panels engaging lug by bolt arrangement, the hold degree of flexible collar sheet to block rubber is changed, will be there is corresponding distortion in block rubber, thus make the rigidity of block rubber occur corresponding change, and also namely corresponding change appears in the frequency of dynamic vibration absorber.Due to two panels engaging lug apparent surface between the change of distance be continuous print, thus make the change of frequency of dynamic vibration absorber also be continuous print.The present invention may be used for the test sizing work of dynamic vibration absorber, in order to from the frequency determining dynamic vibration absorber soon, accurately.The present invention also can improve the adaptability of dynamic vibration absorber, and namely same dynamic vibration absorber can be come for different auto parts and components by frequency adjustment.The present invention has structure advantage simple, easy to use.
As preferably, described bolt arrangement comprises screw bolt and nut block, described nut block be fixed therein an engaging lug away from the surface of another engaging lug.This preferred version, two panels engaging lug is provided with coaxial through hole, bolt from one of them engaging lug through hole be connected with nut block through the through hole of two engaging lugs successively, this preferred version structure is simply, easy to use.
As preferably, described bolt is hexagon socket head cap screw.This preferred version, compact structure, easy to use.
As preferably, the width of clip is more than or equal to the height 1/4th of block rubber, is less than or equal to 1/3rd of block rubber height.The width of clip described here, the i.e. width of flexible collar sheet.This preferred version, the adjustment of the frequency of dynamic vibration absorber is easy and adjustment range is large.
As preferably, engaging lug and the welding of flexible collar sheet.This preferred version, structure is simple, and manufacturing is easy.
In sum, the beneficial effect that the present invention brings is: can carry out continuous setup to the frequency of dynamic vibration absorber, may be used for the test sizing work of dynamic vibration absorber, in order to from the frequency determining dynamic vibration absorber soon, accurately, also can improve the adaptability of dynamic vibration absorber, namely same dynamic vibration absorber can be come for different auto parts and components by frequency adjustment.The present invention has structure advantage simple, easy to use.
