Abstract
The utility model provides a damp power auxiliary shock absorber which comprises a mass block, a damp viscous-elastic material, a supporting plate, a left reset spring and a right reset spring. The damp viscous-elastic material is bonded between the bottom face of the mass block and the supporting plate. The left reset spring and the right reset spring are arranged between two lateral sides of the mass block and the inner lateral sides of the two lateral walls of the supporting plate and connected with the supporting plate, and the supporting plate is fixedly arranged on a power assembly hanging support through a bolt. By changing local parameter adjusting of the damp shock absorber, the damp auxiliary shock absorber capable of meeting different shock absorbing requirements can be designed, redesign and development can be prevented, cost is saved, and generality is good.
Description
Technical field
The utility model relates to power assembly and car load vibration insulating system.
Background technique
In power assembly and car load vibration damping matching process, due to the harsh requirement of suspension system energy decoupling and frequency distribution, often there is the vibration isolating effect of independent suspension very poor, can't meet car load to the vibration requirement.Due to the formation whole system that respectively suspends, between them, be interactional, if realize noise Noise, vibration Vibration, the smoothness Harshness of the NVH(automobile of car load) requirement, just must redesign mounting structure, rigidity, angle and the mounting point of whole suspension system.This can extend the construction cycle on the one hand, increases cost of production; What is more important, suspension system newly developed can improve the independent suspension anti-vibration performance, but also can cause the decline of other a certain vibration isolating effects that suspend.
Summary of the invention
The present invention is intended to overcome the poor defect of the local vibration isolation of suspension system, and a kind of power assembly damping auxiliary damper is provided, in the situation that do not change whole suspension system, realizes local good effectiveness in vibration suppression, reaches the level of damping of improving car load.
The present invention realizes like this, a kind of power assembly damping auxiliary damper, comprise mass block, the damping viscoelastic material, dunnage, left Returnning spring, right Returnning spring, be bonded with the damping viscoelastic material between mass block bottom surface and dunnage, left Returnning spring two ends are fixedly installed in respectively between mass block left surface and dunnage inner side surface, right Returnning spring two ends are fixedly installed in respectively between mass block right flank and another inner side surface of dunnage, and dunnage is bolted and is installed on powerplant mount bracket.
The utility model can only need, by changing the quality of mass block, to realize the vibration damping of different parts and frequency to have good versatility without power assembly and car load suspension system are redesigned to improvement, simple in structure, cost-saving.
The accompanying drawing explanation
Fig. 1 is power assembly damping auxiliary damper assembling schematic diagram.
In Fig. 1,1. mass block, 2. left Returnning spring, 3. right Returnning spring 4. damping viscoelastic materials, 5. dunnage, 6. powerplant mount bracket.
Embodiment
Below in conjunction with Fig. 1, the utility model is illustrated.
As shown in Figure 1, a kind of power assembly damping auxiliary damper, comprise mass block 1, damping viscoelastic material 4, dunnage 5, left Returnning spring 2, right Returnning spring 3, be bonded with damping viscoelastic material 4 between mass block 1 bottom surface and dunnage 5, left Returnning spring 2 two ends are fixedly installed in respectively between mass block 1 left surface and dunnage 5 inner side surfaces, right Returnning spring 3 two ends are fixedly installed in respectively between mass block 1 right flank and dunnage 5 another inner side surfaces, dunnage 5 compare Hou positions, bottom surface have two bolts hole, by two bolts, be fixedly installed on powerplant mount bracket 6.The powerplant mount bracket 6 of principal oscillation system in Fig. 1 and and dunnage 5 form; Parasitic vibration system consists of mass block 1 and damping viscoelastic material 4 and spring 2 and 3.Left Returnning spring 2 and right Returnning spring 3 are realized the buffering of 1 pair of substantially horizontal transient impact of mass block by corresponding elongation and compression.The steel that mass block 1 is larger by density forms, can realize controlledization of its volume, and dunnage 5 is ensureing under technique and intensity in order to reduce its quality as far as possible, select the aluminium sheet that density is less, so that its quality can be ignored, damping viscoelastic material 4 has the double action of spring and damper, can realize absorbing and shaking and catabiotic purpose under resiliently deformable.In the time of in working order, above-mentioned principal oscillation system and parasitic vibration system are together done simple harmonic oscillation, and the natural frequency of the natural frequency of parasitic vibration system and principal oscillation system can be by calculating.When if the natural frequency of the natural frequency of parasitic vibration system and principal oscillation system differs very little (General Requirements is 5%), two systems produce resonance, now class elastic strain absorbing vibrational energy occurs in the damping viscoelastic material on damping shock absorber 4, consumes vibrational energy simultaneously.And impact for the unexpected substantially horizontal that limits transient state, the left Returnning spring 2 between the inner side surface of mass block 1 and dunnage 5 two sides and right Returnning spring 3 are controlled by corresponding compression and elongation.If change the parameter of damping shock absorber, as the rigidity of damping constant, rigidity, left Returnning spring 2 and the right Returnning spring 3 of the quality of mass block 1, damping viscoelastic material 4 and quality of dunnage 5 etc., just can design the damping auxiliary damper that can adapt to different occasion vibration isolation requirements, vibration damper is installed on powerplant mount bracket 6, can realizes improving the purpose of car load vibration.
The utility model has solved by the bad local anomaly vibration problem caused of power assembly suspension system vibration isolating effect, only need carry out the local parameter adjustment to suspension system, just can be applicable to different vibration damping requirements, avoid the redesign exploitation, cost-saving, and there is good versatility.
