Description

Automobile sound absorber assembly

Technical field

The utility model relates to auto parts machinery field, particularly a kind of automobile sound absorber assembly.

Background technology

Automotive muffler, is again exhaust silencer, is mounted in a kind of member of automobile exhaust pipe afterbody, its workWith being speed and the pressure from engine combustion gas for reduction, to reach the object of noise decrease.

At present, automotive muffler generally adopts the mode of hook and rubber hanging assembling, and the general employing of hook is commonSteel, are squeezed into pier nose by its one end, are linked and packed with rubber hanging. Although this structure technique is simple,But after assembling, having following problem: rubber hanging attitude cannot be adjusted, there is torsional deformation in rubber hanging, andAnd silencer can produce certain vibration with travelling of automobile, vibration can cause the axial float of rubber hanging,Make lockup capacity poor, also easily cause rubber hanging abnormal sound, fracture, abrasion deformation, when serious, can be damaged toSilencer, even needs to change muffler ASSY, and the three guarantees maintenance cost after sale of producer is improved. Meanwhile,The vibration that silencer is produced due to running car also can cause certain damage to silencer itself, need takeEffect means reduce the vibration of silencer, extend its service life.

Utility model content

In view of this, the utility model provides a kind of automobile sound absorber assembly, easy for installation, Stability Analysis of Structures, GuFixed firm, can solve abnormal sound, fracture, abrasion deformation, axle that existing rubber hanging brings due to confined stateTo problems such as plaies, and can greatly reduce the vibration that silencer produces in vehicle traveling process.

Automobile sound absorber assembly of the present utility model, comprises that muffler shell and at least one group are for hanging silencerSuspending assembly, the overcoat that described suspending assembly comprises inner sleeve, be fixedly connected with muffler shell and grippingBe arranged on inner sleeve and the outer inner room vibration isolation air bag for vibration isolation.

Further, be fixedly installed rubber bodies in inner sleeve, described rubber bodies through forms lifting hole(eyelet).

Further, rubber bodies sulfuration is fixedly installed in described and puts.

Further, in vibration isolation air bag, be filled with damping fluid.

Further, inner sleeve and described overcoat are metal material and make.

Further, overcoat is connected with muffler shell by arched arm, and arched arm is to be arranged on two of overcoat both sidesIndividual.

Further, arched arm and muffler shell junction are for seamlessly transitting structure.

The beneficial effects of the utility model: automobile sound absorber assembly of the present utility model, the inner sleeve of suspending assembly andOuter inner room arranges vibration isolation air bag and forms air vibration isolation, easy for installation, uses reliable.

Brief description of the drawings

Below in conjunction with drawings and Examples, the utility model is further described.

Fig. 1 is the utility model structural representation;

Fig. 2 is the utility model structure side view.

Detailed description of the invention

Fig. 1 is the utility model structural representation, and Fig. 2 is the utility model structure side view, as shown in the figure:The automobile sound absorber assembly of the present embodiment, comprises that muffler shell 1 and at least one group are for hanging hanging of silencerHanging component, the overcoat 3 that described suspending assembly comprises inner sleeve 2, be fixedly connected with muffler shell 1 and clamping are solidSurely be arranged on the vibration isolation air bag 4 for vibration isolation between inner sleeve 2 and overcoat 3; In inner sleeve 2, be fixedly installed rubber bodies5, described rubber bodies 5 throughs form lifting hole(eyelet) 6; Wherein, suspending assembly arranges two groups, for suspension hookFrame connects, and the coupler body interference fit of suspension hook frame forms fixing through lifting hole(eyelet) 6, outside the outer wall of vibration isolation air bag 4 is close toOverlap 3 inwalls, inwall is close to inner sleeve 2 outer walls and is formed fixingly, and vibration isolation air bag 4 is enclosed construction, its inwallMake by elastomeric material with outer wall.

In the present embodiment, rubber bodies 5 sulfurations are fixedly installed in inner sleeve 2; Bonding strength is high, is difficult for producing phaseTo movement.

In the present embodiment, 4 li, vibration isolation air bag is filled with damping fluid; Damping fluid can be fluid, forms effectiveness in vibration suppression.

In the present embodiment, inner sleeve 2 and overcoat 3 are metal material and make; Intensity is high, not fragile.

In the present embodiment, overcoat 3 is connected with muffler shell 1 by arched arm 7, and arched arm 7 is for arrangingAt two of overcoat 3 both sides; Arched arm 7 and muffler shell 1 junction are for seamlessly transitting structure.

Finally explanation, above embodiment is only unrestricted in order to the technical solution of the utility model to be described,Although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art shouldWork as understanding, can modify or be equal to replacement the technical solution of the utility model, and not depart from this realityBy aim and the scope of new technique scheme, it all should be encompassed in the middle of claim scope of the present utility model.
