Technical field
This utility model relates to car engine suspension structure, is specifically related to engine front mounting.
Background technology
Existing engine front mounting generally by subframe link, endless metal shell, metal core and
Vulcanite forms.In metal core is centrally positioned in endless metal shell and by vulcanite and annular
Metal shell is fixed together, and endless metal shell, metal core and vulcanite collectively constitute rubber lining
Set plays the effect of damping.
The subject matter that structure exists now is: (1) subframe link uses casting, and mould becomes
This height, and weight is big；(2) the structure design of rubber bushing is unreasonable, causes suspension static stiffness curve to hold
Flex point easily occur, the NVH poor performance of car load, damping effect is bad.
Utility model content
This utility model is intended to optimize the structure of front-suspension, reduces and manufactures and design cost, it is to avoid suspension static
There is flex point in rigidity curve, improves damping effect and the NVH performance of car load.
To this end, the technical scheme that this utility model is used is: a kind of automobile engine front mounting, including
Subframe connecting plate, endless metal shell and metal core, described metal core is centrally positioned in annular gold
Genus shell is interior and is fixed together with endless metal shell by vulcanite, on described metal core under width
Narrow, waist has been centrally located front-suspension bracket connecting hole, is arranged at intervals with two about metal core top
Individual first lightening hole, is arranged at intervals with two the second lightening holes, described sulfuration about metal core bottom
Rubber includes the "eight" shape part being supported between metal core and endless metal shell, is positioned at metal
The arch section at fuse top, and arch section overlaps with the axial line of front-suspension bracket connecting hole；
Described subframe connecting plate is " u "-shaped plate, " u "-shaped plate opening up and curved, subframe
Connecting plate is welded on the underface of endless metal shell by arc oral area, and the bottom of described " u "-shaped plate is left
The right side is provided with two subframe connecting bolts straight down.
Preferred as such scheme, the root middle position of each side plate of described subframe connecting plate
Punching has triangle reinforcement, to increase the intensity of subframe connecting plate, prevents deformation.
Further, the root of described arch section is connected with the root of "eight" shape part, "eight" shape
The left part of part is connected by the coupling part bottom metal core with right part, thus by whole
In metal core is wrapped in.
It addition, the cross section of described first lightening hole is right-angled trapezium, the cross section of the second lightening hole is straight
Angle triangle, and the cross-sectional area of the first lightening hole is more than the cross-sectional area of the second lightening hole, it is ensured that structure
On the premise of performance, reduce cost to greatest extent, alleviate weight.
That side width minimum that two described first lightening holes are relative, is gradually increased towards left and right sides width；
That side width minimum that two the second lightening holes are relative, is gradually increased towards left and right sides width；Further
Optimize the structure of first, second lightening hole.
The beneficial effects of the utility model: subframe connecting plate uses sheet metal component to be stamped to form, simple in construction,
Avoid die sinking, reduce manufacture and design cost；Optimize vulcanite and the structure of metal core, position
Putting and shape, when variator vibration can be avoided excessive, there is flex point, makes Static stiffness in suspension static stiffness curve
Curve seamlessly transits at non-linear section, improves damping effect and the NVH performance of car load；Optimize metal core
Structure, it is ensured that while structural strength, alleviate weight, reduce cost.
Accompanying drawing explanation
Fig. 1 is axonometric drawing of the present utility model.
Fig. 2 is front view of the present utility model.
Detailed description of the invention
Below by embodiment and combine accompanying drawing, the utility model is described in further detail:
Shown in Fig. 1 Fig. 2, a kind of automobile engine front mounting, mainly by subframe connecting plate 1,
Endless metal shell 2 and metal core 3 form.Metal core 3 is centrally positioned in endless metal shell 2
In and pass through vulcanite 4 be fixed together with endless metal shell 2.Endless metal shell 2, metal-cored
Son 3 and vulcanite 4 collectively constitute rubber bushing, are connected between subframe and variator, play and subtract
The effect of shake.Whole rubber bushing is bilateral symmetry.
Metal core 3 uses structure wide at the top and narrow at the bottom, it is simple to top arranges sufficiently long arch section 42.
The waist of metal core 3 has been centrally located front-suspension bracket connecting hole 31, for being connected with front-suspension bracket.
Two the first lightening holes 32 it are arranged at intervals with about metal core 3 top, left in metal core 3 bottom
Right septum is provided with two the second lightening holes 33.Preferably, the cross section of the first lightening hole 32 is right angle ladder
Shape, the cross section of the second lightening hole 33 is right angled triangle, and the cross-sectional area of the first lightening hole 32 is big
Cross-sectional area in the second lightening hole 33.It addition, that side width that two the first lightening holes 32 are relative
Minimum, is gradually increased towards left and right sides width；That side width minimum that two the second lightening holes 33 are relative,
