Chinese utility model patent specification CN204553655U discloses a kind of vehicle engine exhaust divided manifold heat insulation
Damping device on cover, including lower lining, upper lining, stainless steel wire, lower lining includes the main part of cylindrical shape and by main part
The bottom annular support part that vertically outwards bending extension is formed, upper lining includes the accessory body portion of cylindrical shape and is hung down by top, accessory body portion
Straight outwards bending extends the annular support portion being formed；The main part of lower lining is arranged in the installing hole of heat shield, and heat shield
It is against the upper surface of the supporting part of described lower lining；The accessory body portion of upper lining is mutually socketed with the main part of described lower lining；No
Rust steel wire is sheathed between heat shield and the cradle portion of described upper lining.Above-mentioned improvement vibration is durable to improve significantly and more steady
Fixed.But there is also some problems, such as: on it, height of lining and lower lining is fixed, through long-time stress effect, stainless steel
, it may happen that thinning phenomenon, there is gap, makes heat shield body send out in the thickness of silk between this cognition of heat shield and stainless steel wire
Going out noise, installing hole receives the effect that stress occurs in heat shield body vibrations direction, causes heat shield installing hole to tear, additionally also
In existence, between lining and lower lining, mismate installs problem error occur.
Utility model content
In view of the deficiency of background technology, technical problem to be solved in the utility model is to provide a kind of sound construction, subtracts
The damping device of the good exhaust pipe thermal insulation shield of shock stability, and solve damping silk screen after permanent use thinning cause heat shield this
The problem of installing hole stress cracking on body.
To this end, the utility model uses following scheme to realize:
The damping device of engine heat shield, including lower lining, upper lining, described lower lining includes the main part of cylindrical shape
And by main part bottom vertically outwards bending extend the annular support part that formed, described upper lining include cylindric accessory body portion and
By the annular support portion that vertically outwards bending extension is formed, top, accessory body portion, described main part has the through hole passing through for bolt,
It is characterized in that: the main part of described lower lining is formed outer main part and interior main part by the segmentation of end face annular groove, in institute
Stating end face annular groove bottom and placing the first damping silk screen, described in described upper lining, lower lining is mutually socketed, described upper lining
Accessory body end surface is connected to the first damping silk screen upper end, and described engine heat shield is connected to the end of the outer main part of described lower lining
It on face, between the annular support portion of described upper lining and described engine heat shield, is provided with the second damping silk screen, described lower lining
Annular support part and described engine heat shield between be provided with the 3rd damping silk screen.
The utility model is further arranged to, the interior main body of a length of described lower lining of the outer main part of described lower lining
The 1/2-2/3 of the length in portion.
The utility model is further arranged to, the interior main part of a length of described lower lining in the accessory body portion of described upper lining
Length 2/3.
By using technique scheme, the utility model can realize following beneficial effect: the utility model devises one
Kind coordinate that fastness is good, the damping device of the engine heat shield of simple in construction, the design of the inside and outside main part of lower lining make its with
The combination of upper lining is more firm, during its use, even if damping silk screen is worn thinning, due in bolt fastening
After, its upper and lower lining is tightly sleeved, and damping silk screen therein is by axial compressive force, owing to damping silk screen has certain storage
The performance of axial stress, during the vibrations of heat shield body, even if the abrasion of damping silk screen is thinning, it is stored in damping silk screen
Stress Release, can make up the gap between damping silk screen and heat shield body, and then reduce during long-time vibrations heat insulation
The stress that cover body bears, prevents its stress from rupturing.And the damping silk screen being arranged in lower lining groove is further strengthened
Its damping performance so that upper and lower lining can be buffered in vibrations, improve the quality of damping device.
Brief description
The utility model has a drawings described below:
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
As it is shown in figure 1, the damping device of engine heat shield disclosed in the utility model, including lower lining the 2nd, upper lining 1,
