Abstract
The utility model discloses an automobile engine exhaust manifold support which takes a vertical block in the middle as a support part; and both surfaces of the support part are respectively connected with a first connecting plane which is connected with an engine part and a second connecting plane which is connected with an exhaust manifold flange. The second connecting plane is connected on the lower end of the support part and is in an L shape with the support part, the first connecting plane is connected on the upper side of the support part and is in the L shape with the support part, and the two connecting planes are mutually staggered and basically in vertical relationship so that the whole support is in a Z-shaped structure. The two connecting planes are respectively provided with strip-shaped holes which are connected with the engine part and the exhaust manifold flange. The support not only can play a supporting role to the exhaust manifold but also does not produce over constraint, so that the stress produced in an X direction due to heating and deformation is released, the problems that the heat stress produced by the exhaust manifold is not effectively released because of too high support rigidity and the exhaust manifold is cracked are solved, and the reliability of the exhaust manifold is improved.
Description
Technical field
The utility model relates to automobile engine exhaust system, is specifically related to a kind of enmgine exhaust supporting structure.
Background technique
Along with national legislation is more and more stricter to the requirement of discharging, in order to reach emission standard, save cost, at present increasing motor car engine begins to adopt stainless exhaust manifold.Because stainless exhaust manifold is compared with the cast iron gas exhaust manifold, wall is thinner and be by punching press, be welded, and the position of gas exhaust manifold is in the hot junction, stressed complexity, so in order to guarantee the intensity of gas exhaust manifold, prevent that gas exhaust manifold from use rupturing, often need supply and exhaust manifold design support, support and locate.
At present, employed gas exhaust manifold support adopts casting or impact briquetting part often on motor, and support itself has stronger rigidity.As shown in Figure 1 more common, gas exhaust manifold support 4 is L type impact briquetting pieces, and manifold support 4 one ends of L type link to each other with gas exhaust manifold flange 3 during assembling, and the other end links to each other with engine components 2.This L type supporting structure is because rigidity is strong, easily gas exhaust manifold is produced excessive constraint, cause support all to have stronger rigidity at directions X and Y direction, gas exhaust manifold can not effectively be discharged at the stress of the directions X that produces the thermal stress maximum, there is the risk of cracking in gas exhaust manifold.
Summary of the invention
For solving the problems of the technologies described above, a kind of enmgine exhaust support that improves structure is provided, when assurance is effectively supported gas exhaust manifold, reduce the constraint of support to it, make things convenient for the release of its thermal stress.
The utility model takes following technological scheme to realize above-mentioned purpose:
A kind of automobile engine to exhaust manifold support, it is connected between engine components and the gas exhaust manifold flange, is used to support gas exhaust manifold.Described support is the supporting portion with a middle vertical piece, connect respectively on the two sides, supporting portion link to each other with engine components first be connected the plane with the gas exhaust manifold flange continuous second be connected the plane.Second connects the lower end that the plane is connected the supporting portion, becomes the L type with the supporting portion, and first connects the upper side edge that the plane is connected the supporting portion, also becomes the L type with the supporting portion, and two connection planes stagger mutually and be vertical relation substantially, makes entire bracket formation zigzag structure.Connect also to have on the planes two and be used for the bar hole that is connected with the gas exhaust manifold flange with engine components, two length that connect bar hole on the planes move towards vertical each other.
During assembling, pass bar hole by bolt and first of support is connected the plane link to each other with the gas exhaust manifold flange, first connects the plane links to each other with engine components (as cylinder body or other fixed components), and this Placement simply, reliably.Bar hole can compensate the size deviation of Y, Z direction, can regulate assembly error, makes assembling easier.The zigzag structure both can (as the Y direction) keep the rigidity of reinforcement on certain direction, satisfy support requirement to gas exhaust manifold, can make gas exhaust manifold certain elastic strain can take place again in another direction (as directions X), rigidity is less relatively, consequent thermal stress can obtain because of the resiliently deformable of gas exhaust manifold support discharging, strengthen the reliability of gas exhaust manifold, avoided gas exhaust manifold that the problem of cracking takes place owing to thermal stress is excessive in the course of the work.
Further, ftracture owing to the stress of itself is concentrated in the course of the work for fear of the gas exhaust manifold support, the supporting portion of described gas exhaust manifold support, first connects the plane and is connected the plane three with second and bends mutually on a whole plate and form, and has all designed fillet at bending part.
This shows, above-mentioned gas exhaust manifold support after improving design can play the effect of support to gas exhaust manifold, be unlikely to again gas exhaust manifold is produced excessive constraint, the stress that gas exhaust manifold is produced owing to temperature distortion at directions X can obtain discharging, thereby solved gas exhaust manifold because the rigidity of support is too high, make its thermal stress that produces in the course of the work can not get effectively discharging and the problem of generation cracking, improved the reliability of gas exhaust manifold.

Embodiment
Below, the utility model is described in further detail in conjunction with the accompanying drawings and embodiments:
Referring to Fig. 2 and Fig. 3, this automobile engine to exhaust manifold support 1 integral body is connected between engine components 2 and the gas exhaust manifold flange 3, gas exhaust manifold support 1 is by being bent to form by a whole plate, be that a vertical piece forms supporting portion 13 in the middle of it, 13 two sides is bent to form respectively that engine components 2 link to each other in the supporting portion first connect plane 11 with link to each other with gas exhaust manifold flange 3 second be connected plane 12, second connects the lower end that plane 12 is positioned at supporting portion 13, with the 13 one-tenth L types in supporting portion, the bending place is a fillet, first connects the upper side edge that plane 11 is connected supporting portion 13, also with the 13 one-tenth L types in supporting portion, the bending place also is designed to fillet, and two connect planes and stagger mutually and be vertical relation.It is vertical each other to connect the length trend that also has bar hole 14 on bar hole 14, the two connection planes on the plane two simultaneously, is connected with engine components 2 (as cylinder body or other fixed components) with gas exhaust manifold flange 3 respectively.
As can be seen from Figure 3, gas exhaust manifold support 1 integral body is the zigzag structure, and it can satisfy the support requirement to gas exhaust manifold, can absorb the thermal stress of gas exhaust manifold by the resiliently deformable of supporting portion 13 again, improves the stressing conditions of gas exhaust manifold.First connects plane 11 is connected the two ends that plane 12 lays respectively at gas exhaust manifold support 1 with second, and the bar hole 14 on these two junction surfaces can be regulated the size of Y direction and Z direction along different direction layouts.Gas exhaust manifold support 1 can avoid gas exhaust manifold support itself to ftracture owing to stress is concentrated at the fillet of bending part design.
