Abstract
The utility model discloses a novel noise control sound structure decoupling membrane, including seal membrane and vibrating diaphragm, shown vibration membrane ring overlaps in sealed outer surface of the film and integration shaping, the edge of vibrating diaphragm is equipped with the ring type seal of longitudinal symmetry, the seal membrane longitudinal symmetry is equipped with annular noise control circle, the intra -annular of noise control circle is equipped with a plurality of noise control bumps, the noise control bump uses the center of seal membrane to distribute as centre of a circle annular. Compared with the prior art, the beneficial effects of the utility model are that: its structure can effectual control its see the production noise in all ring edge borders because of fluid pressure impactes to the travelling comfort of whole car has been avoided influencing because of its noise. Adopt the utility model discloses a novel noise control sound structure decoupling membrane engine hydraulic mount's under can effectual promotion dynamic behavior to all has of great significance to aspects such as the driving travelling comfort of car, securities.
Description
Technical field
This utility model is related to automobile engine hydraulic suspension field of mechanical technique and in particular to a kind of novel noise-insulating
Structure decoupling diaphragm.
Background technology
In dynamic power machine, suspending apparatus are one of important component parts therein, and the quality of its service behaviour will be directly
Have influence on the aspects such as mechanical vibration, impact and noise.For example, automobile power assembly suspending is for connecting power assembly and car
Body, it plays the effect supporting power assembly, isolation power assembly and road excitation.With people for car comfort and quiet
The continuous lifting of sound performance requirement, decoupling type hydraulic mount is due to having the big damping of the low volume of large amplitude, the little damping of little amplitude great number
Characteristic, be therefore widely applied on automobile, to meet comfortableness under the conditions of different traveling for the automobile and vibration isolation, sound insulation
Needs.
Development and living standards of the people with domestic economy are constantly lifted, and family-sized car increasingly spreads to commonly
Family, consumer's also requirement more and more higher to every quality of car load.And the vibration producing during the work of topping up electromotor will
Form pressure differential in upper lower liquid chamber, promote the topping up of upper liquid chamber to move to lower liquid chamber, mainly transported by inertia channel in low frequency
Dynamic, during high frequency, the liquid due to inertia channel has little time to move due to electronic curing phenomenon, and now decoupling diaphragm will be upper and lower
Up-down vibration in runner, can encounter the confined planes of flow passage system, at this moment will produce construct noise during decoupling diaphragm vibration.At present
The decoupling diaphragm of the suspension of topping up electromotor of application, due to lacking buffering when moving up and down in runner, is therefore produced with runner
Rigid contact, causes noise larger, and the noise qualities of impact car load make the driving experience of user bad.
In sum, need the structure of decoupling diaphragm is improved, to eliminate rigid contact, decrease or even eliminate and make an uproar
Sound.
Utility model content
The purpose of this utility model is to overcome deficiency of the prior art, providing a kind of novel noise-insulating structure decoupling
Diaphragm, solve the problems, such as decouple diaphragm moves up and down in runner produce noise larger.
For solving above-mentioned technical problem, the technical solution of the utility model is：
A kind of novel noise-insulating structure decoupling diaphragm, including diaphragm seal and vibrating diaphragm, shown vibrating diaphragm is located on diaphragm seal
Outer surface and integrated molding, the edge of described vibrating diaphragm is provided with laterally zygomorphic O-ring seal, and described diaphragm seal is right up and down
Claim to be provided with annular noise control circle, be provided with some noise control salient points in the ring of described noise control circle, described noise control salient point is with the center of diaphragm seal
For center of circle annular spread.
Preferably, it is provided with groove between laterally zygomorphic described O-ring seal.
Compared with prior art, the beneficial effects of the utility model are：This utility model using preferred design, set
Count simple compact structure, comprehensively take into account the factor it is possible that noise, and eliminate influence factor, its anti-noise
Effect is all good, and its structure can effectively control it to clash into surrounding enviroment because of fluid pressure to see generation noise, thus avoiding
Affect the comfortableness of car load because of its noise.Can effectively be carried using novel noise-insulating structure decoupling diaphragm of the present utility model
The dynamic property of engine hydraulic mount belonging to rising, thus all have great to aspects such as the driver comfort of automobile, safeties
Meaning.
Brief description
Fig. 1 is axonometric chart of the present utility model.
In accompanying drawing：1st, diaphragm seal；2nd, vibrating diaphragm；3rd, sealing ring；4th, noise control circle；5th, noise control salient point；6th, groove.
Specific embodiment
Effect for making to architectural feature of the present utility model and reached has a better understanding and awareness, in order to relatively
Good embodiment and accompanying drawing cooperation detailed description, are described as follows：
A kind of novel noise-insulating structure decoupling diaphragm, including diaphragm seal 1 and vibrating diaphragm 2, shown vibrating diaphragm 2 is located on sealing
Film 1 outer surface and integrated molding, the edge of described vibrating diaphragm 2 is provided with laterally zygomorphic O-ring seal 3, described diaphragm seal 1
Symmetrical above and below be provided with annular noise control circle 4, be provided with some noise control salient points 5 in the ring of described noise control circle 4, described noise control salient point 5 is with close
The center of sealer 1 is center of circle annular spread, is provided with groove 6 between laterally zygomorphic described O-ring seal 3.
Described decoupling diaphragm is natural rubber, and described sealing structure circle 3 and vibrating diaphragm 2 and diaphragm seal 1 play close jointly
The effect of sealing liquid body, vibrating diaphragm 2 is decoupling diaphragm groundwork region, noise control circle 4 and noise control salient point 5 be prevent from decoupling diaphragm because
Clash into and produce and noise.
A kind of novel noise-insulating structure decoupling diaphragm described in the utility model, medium design is the larger diaphragm seal of rigidity
1, can effectively control its upper and lower oscillating region, replace 1 vibration of diaphragm seal that traditional medium design is less rigidity to hit
Hit surrounding enviroment part and produce abnormal sound, have also been devised noise control circle 4, noise control salient point 5 about 1 respectively in diaphragm seal, further simultaneously
Carry out its anti-noise.
The main working parts vibrating diaphragm 2 of decoupling diaphragm designs in neighboring area, and thickness is less, and distance is up and down
Surrounding enviroment part has very big safe distance, instead of traditional vibrating diaphragm 2 in the too near design of intermediate distance surrounding enviroment part,
The generation of the noise avoiding further.A kind of described novel noise-insulating structure decoupling diaphragm, can prevent further because decoupling film
Piece and the noise phenomena that produces.
Of the present utility model ultimate principle, principal character and of the present utility model advantage have been shown and described above.One's own profession
The technical staff of industry it should be appreciated that this utility model is not restricted to the described embodiments, described in above-described embodiment and description
Simply principle of the present utility model, on the premise of without departing from this utility model spirit and scope, this utility model also has respectively
Plant changes and improvements, these changes and improvements both fall within the range of claimed this utility model.This utility model requires
Protection domain defined by appending claims and its equivalent.
