Abstract
The utility model provides a damping vibration absorber, comprising a damping material, a mass block, and a connecting piece, the mass block is circumferentially disposed at the external of the damping material, and is tightly connected with the damping material. The connecting piece goes through the damping material, is tightly connected with the damping material, and is disposed at the center of the whole vibration absorber. The damping vibration absorber can effectively rapidly destroy the natural resonance frequency of a mechanical system, makes the mechanical system always work stably in a non-resonance frequency band in dynamic work, can not only eliminate resonance energy output by an engine, but can also effectively eliminate excitation and impact energy output from a pavement, and can effectively complete protection of an automobile system.
Description
Technical field
The utility model relates to a kind of automobile damping absorber, relates in particular to a kind of damping absorber.
Background technique
Engine mounting is the characteristic that vibration amplitude is declined gradually by damping, and the interior friction the vibrational energy of input by the damping that suspends is converted into thermal energy consumption and dissipates.Damping contributes to the resonance amplitude of mechanical system of decaying, thereby avoids structure because vibration stress reaches capacity, to cause component damage.The damping function of engine mounting, is subject to the situation after moment impact for mechanical system, can return to very soon steady state, reduces the sound radiation producing because of mechanical vibration simultaneously, reduces mechanical noise.The damping function of engine mounting can keep the dynamic stability of motor in dynamic environment, stable service behaviour during raising motor is dynamic.Substantially there is in actual use the decay of the transmission be difficult to stop resonance phenomenon and structural vibration in car engine suspension, if the vibration system of one degree of freedom, the design of its damping ratio under the constant situation of structure easily the design by rubber compounding be achieved.But the mechanical system that motor car engine is six-freedom degree, reaches outstanding vibration damping, noise reduction difficulty by engine mounting larger, and effect is not ideal enough, particularly to the transition of some intrinsic resonant frequencies of vibration system and eliminate all not ideal enough.For sort this problem out bump leveller just arises at the historic moment.As the application number Chinese utility model patent application that is 201110075488.0, a kind of frequency-adjustable bump leveller being arranged on automobile suspension rack is disclosed, it comprises base, block rubber and mass block, and block rubber is fixed on base, and mass block is fixed on block rubber; On described mass block, carry threaded stem, at least two variable-quality pieces are housed on described threaded stem, in threaded stem upper end, by nut, tighten fixing described variable-quality piece.But after employing technique scheme, the effect of damping shock-absorbing is unsatisfactory.
