Description
Technical field
The present invention relates to automobile technical field, be specifically related to a kind of heat-insulating cushion block installing exhaust manifold.
Background technology
Exhaust manifold is with tap line, and it is connected with engine cylinder cap, the aerofluxus of each cylinder can be put together importing
In exhaust main, as illustrated in fig. 1 and 2, on the adpting flange 1b at the air inlet of each divided manifold 1a of exhaust manifold 1, along
The circumferentially-spaced installing hole offering stud, on the end face of each cylinder air vent of cylinder head 2, correspondence offers internal thread hole, actual
During installation, the installed surface of adpting flange 1b fits with the air vent end face of cylinder head 2, and both binding faces can arrange sealing
Pad (Fig. 1,2 not shown in), one end of such stud 3 is through on the installing hole on adpting flange 1b and gasket seal
Through hole can be implemented threaded engagement with the internal thread hole in cylinder head 2 and fix, the spiral shell then screwed in by the other end of stud 3
Adpting flange 1b on female 4 compression exhaust manifolds 1 can realize the connection of exhaust manifold 1 and cylinder head 2 and fix.
It can be seen that after exhaust manifold 1 actual installation completes, nut 4 is and the connection on exhaust manifold 1 from Fig. 1-2
Flange 1b directly contacts, and now along with the lifting of engine performance, electromotor row's temperature is more and more higher, and electromotor works
Time, especially engine with supercharger, the temperature of exhaust manifold is the highest, the most even can exceed the operating temperature range of nut 4, thus
Cause nut 4 to loosen to lose efficacy, so certainly will cause generation gas leak phenomenon at gasket seal.For nut 4 asking because of high temperature failure
Topic, the conventional method taked at present is dependent on stud 3 import, resistant to elevated temperatures and nut 4, but so improves production undoubtedly
Cost, and receipt period is longer.
Summary of the invention
It is an object of the invention to provide a kind of simple in construction, the heat-insulating cushion block of service-strong installation exhaust manifold.
For achieving the above object, the technical solution used in the present invention is: a kind of heat-insulating cushion block installing exhaust manifold, its
Being characterised by: include thermostable heat insulation cushion block, the main body of heat-insulating cushion block offers through hole, described through hole is for connecting aerofluxus discrimination
The stud of pipe and cylinder head passes.
Use having the beneficial effects that of technique scheme generation: compared with prior art, can by the layout of the present invention
To effectively act as heat-blocking action, thus keep away for the nut compressing exhaust manifold because temperature is too high and loosening, in turn result in leakage
The phenomenon of gas occurs.

Detailed description of the invention
A kind of heat-insulating cushion block installing exhaust manifold, as shown in figures 2-6, it is characterised in that: include thermostable heat insulation
Cushion block 10, the main body of heat-insulating cushion block 10 offers through hole 11, and described through hole 11 is for connecting exhaust manifold 1 and the stud of cylinder head
3 pass.During actual application, as it is shown in figure 5, described heat-insulating cushion block 10 is arranged in exhaust manifold 1 and for compressing exhaust manifold 1
Nut 4 between so that exhaust manifold 1 and nut 4 are spaced apart, that is both will not directly contact, with prior art
Compare, heat-blocking action can be effectively acted as by the layout of the present invention, thus avoid nut 4 too high and loosening because of temperature, enter
And cause the phenomenon of gas leakage to occur.Present configuration is simple, dependability is high.
As further preferred version, as seen in figures 3-6, on described heat-insulating cushion block 10 interval be disposed with two through hole 11,
11a, two through hole 11,11a core direction, hole is consistent and two through hole 11, Kong Xin distance and the adjacent stud on exhaust manifold 1 of 11a
3, the axial line distance of 3a is equal, and so during actual application, a heat-insulating cushion block 10 is for the nut 4 on adjacent two studs 3,3a
Share, so make heat-insulating cushion block 10 that the space between the nut 4 on adjacent two studs 3,3a is also played the effect of thermal resistance
Really, the temperature thus avoiding nut 4 further is too high.
It should be noted that heat-insulating cushion block 10 itself belongs to heatproof material, therefore during actual application, the temperature of himself also must
The highest, if its temperature cannot disperse in time, use the temperature that will also result in nut 4 to rise for a long time, to this end, the present invention
Preferably employ techniques below scheme, as seen in figures 3-6, the spaced apart louvre being provided with through main body on described heat-insulating cushion block 10
12, the face that the core direction, hole of louvre 12 is perpendicular to two through hole 11, the hole core of 11a is constituted, so on the one hand by louvre 12
Distribution the temperature of heat-insulating cushion block 10 self can be made to be reduced in time, the core direction, hole additionally, due to louvre 12 is perpendicular to two
The face that through hole 11, the hole core of 11a are constituted, so that the flow direction of the heat dispersed from louvre 12 is remote from through hole 11,
That is be remote from the position at nut 4 place, integrating this technical scheme and can improving the heat-sinking capability of heat-insulating cushion block 10 self,
Can guarantee that again the heat-blocking action to nut 4, offering of louvre 12 may also operate as loss of weight effect simultaneously.
Preferably, shown in 3-5, the side orifice end of through hole 11 faces out protruding composition boss 13, described boss 13
Lean for the nut 4 compressing exhaust manifold 1 with on stud 3, during such actual installation, facilitate nut 4 coincide be resisted against every
The boss 13 of hot cushion block 10, thus improve nut 4 be fixed effect.
Concrete, described heat-insulating cushion block 10 is processed into by heating resisting metal；Louvre 12 on described heat-insulating cushion block 10 in
Rectangular array formula is distributed, to ensure heat-insulating cushion block 10.
Further, through hole 11, louvre 12 on described heat-insulating cushion block 10 are castings, this is because according to machine
Add mode manufactures and can make that production efficiency is the lowest, difficulty of processing is relatively big, it is advantageous to be to use casting, needs explanation
, casting tolerance is relatively big, so the design in hole should take into full account manufacturing tolerance, it is ensured that between Kong Yukong, between hole and outer wall
Minimum wall thickness (MINI W.).
