Abstract

The utility model provides an exhaust gasket of an integrated heat shield. The exhaust gasket of the integrated heat shield is arranged on the heat shield, the exhaust gasket comprises two gaskets which are a first gasket and a second gasket, the heat shield is arranged between the first gasket and the second gasket, and the heat shield extends to the upper portions of the gaskets. The exhaust gasket of the integrated heat shield not only has a sealing function, but also has a heat protection function, and is compact in structure.

Description

A kind of exhaust gaskets of integrated thermal shield

Technical field

The utility model relates to a kind of heat extraction pad, relates in particular to a kind of exhaust gaskets of integrated thermal shield.

Background technique

Existing exhaust pipe gasket adopts individual layer or two-layer gasket seal, exclusion seal effect is only played in such design, but row's temperature of gas exhaust manifold side is higher, must increase thermal shield, gasket seal and thermal shield are separated design by prior art, and level of integration is lower, assembling trouble, complex structure, and can not well play heat insulation effect.

Model utility content

In order to overcome the above problems, the utility model provides a kind of exhaust gaskets of integrated thermal shield, and it is the Packed function of tool not only, and has thermo-lag effect, simultaneously compact structure.

In order to reach above object, the utility model provides a kind of exhaust gaskets of integrated thermal shield, be arranged on thermal shield, exhaust gaskets comprises two pads, be respectively the first pad and the second pad, wherein thermal shield is arranged between the first pad and the second pad, and thermal shield extends to the top of pad.

Preferably, the upper part of described the first pad and the second pad is close to thermal shield, and lower part arranges with thermal shield interval, between the top and bottom of its Intermediate gasket, connects by slope section transition.

Preferably, the upper part of described the first pad and the second pad is close to thermal shield with lower part, between the top and the bottom of pad, connects by a bandy arc.

Preferably, the half of the lower partial-length of described pad is greater than the perpendicular distance between pad underpart and thermal shield underpart, and perpendicular distance between pad underpart and thermal shield underpart is not less than 0.

Preferably, the perpendicular distance between pad underpart and thermal shield underpart equals 0.

The utility model is compared to the concrete advantage of prior art: on the basis of two-layer exhaust gaskets, increased one deck thermal shield in the prior art, in the function of sealing, increased again thermo-lag effect, simultaneously compact structure.

Embodiment

Below, by exemplary mode of execution, the utility model is specifically described.But should be appreciated that element, structure and the feature in a mode of execution also can be attached in other mode of executions valuably in the situation that further not narrating.

Referring to Fig. 1, it is the scheme of installation of exhaust gaskets and thermal shield in the utility model; Fig. 2 is the side view of the exhaust gaskets of integrated thermal shield in the utility model.As shown in the figure, the exhaust gaskets of this integrated thermal shield is arranged on thermal shield 2, this exhaust gaskets 1 comprises two pads, be respectively the first pad 11 and the second pad 12, wherein thermal shield 2 is arranged between the first pad 11 and the second pad 12, and thermal shield 2 extends to the top of pad 1, to play heat insulation effect.

Referring to Fig. 3, be in the utility model between exhaust gaskets and thermal shield the first the schematic diagram of relation is set.As shown in Figure 3, when between this exhaust gaskets and thermal shield, half muscle is connected, the upper part of the first pad 11 and the second pad 12 is close to thermal shield 2, and lower part arranges with thermal shield 2 intervals, and the upper part of its Intermediate gasket 1 and bottom are connected by slope section transition between dividing.If the lower partial-length of above-mentioned pad 1 is a, perpendicular distance between the underpart of above-mentioned pad 1 and the lower end of thermal shield 2 is b, will make exhaust gaskets and thermal shield good before, needing satisfied condition be a/2 > b >=0, wherein preferred b=0.

Referring to Fig. 4, be in the utility model between exhaust gaskets and thermal shield the second the schematic diagram of relation is set.As shown in Figure 4, when between this exhaust gaskets and thermal shield, full muscle is connected, the upper part of the first pad 11 and the second pad 12 is close to thermal shield 2 with lower part, and connects by a bandy arc between the top and the bottom of pad.If the length of the lower part of above-mentioned pad 1 is a, the perpendicular distance between the underpart of above-mentioned pad 1 and the underpart of thermal shield 2 is b, will make exhaust gaskets and thermal shield good before, and needing satisfied condition be a/2 > b >=0.

Be appreciated that the utility model is described by some embodiments, those skilled in the art know, in the situation that not departing from spirit and scope of the present utility model, can carry out various changes or equivalence replacement to these features and embodiment.In addition, under instruction of the present utility model, can modify to adapt to concrete situation and material and can not depart from spirit and scope of the present utility model these features and embodiment.Therefore, the utility model is not subject to the restriction of specific embodiment disclosed herein, and the embodiment within the scope of all the application's of falling into claim belongs in the scope that the utility model protects.
