Abstract
The utility model discloses the rubber bushing of a kind of automobile engine front mounting, in metal core is centrally positioned in endless metal shell and it is fixed together with endless metal shell by vulcanite, metal core is wide at the top and narrow at the bottom, waist has been centrally located front-suspension bracket connecting hole, two the first lightening holes it are arranged at intervals with about metal core top, two the second lightening holes it are arranged at intervals with about metal core bottom, vulcanite includes the "eight" shape part being supported between metal core and endless metal shell, it is positioned at the arch section at metal core top, and arch section overlaps with the axial line of front-suspension bracket connecting hole；The root of arch section is connected with the root of "eight" shape part, and the left part of "eight" shape part is connected by the coupling part bottom metal core with right part, thus in whole metal core is wrapped in.Optimize structure, it is to avoid flex point occurs in suspension static rigidity curve, improve damping effect and the NVH performance of car load.
Description
Technical field
This utility model relates to car engine suspension technical field, is specifically related to the rubber of engine front mounting
Glue bush structure.
Background technology
Existing engine front mounting is generally made up of subframe link and rubber bushing, rubber bushing by
Endless metal shell, metal core and vulcanite composition.Metal core is centrally positioned in outside endless metal
In shell and being fixed together with endless metal shell by vulcanite, rubber bushing plays the effect of damping.
The subject matter that structure exists now is: the structure design of rubber bushing is unreasonable, causes suspension static
Easily there is flex point in stiffness curve, and 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 rubber bushing, it is to avoid suspension static rigidity curve occurs
Flex point, improves damping effect and the NVH performance of car load.
To this end, the technical scheme that this utility model is used is: the rubber of a kind of automobile engine front mounting
Lining, including endless metal shell and metal core, described metal core is centrally positioned in outside endless metal
In shell and being fixed together with endless metal shell by vulcanite, described metal core is wide at the top and narrow at the bottom,
Waist has been centrally located front-suspension bracket connecting hole, is arranged at intervals with two about metal core top
One lightening hole, is arranged at intervals with two the second lightening holes, described vulcanite about metal core bottom
Including the "eight" shape part being supported between metal core and endless metal shell, it is positioned at metal core
The arch section at top, and arch section overlaps with the axial line of front-suspension bracket connecting hole；
The root of described arch section is connected with the root of "eight" shape part, a left side for "eight" shape part
Side part is connected by the coupling part bottom metal core with right part, thus by whole metal core
In being wrapped in.
Preferred as such scheme, the cross section of described first lightening hole is right-angled trapezium, the second loss of weight
The cross section in hole is right angled triangle, and the cross-sectional area of the first lightening hole is more than the transversal of the second lightening hole
Area, it is ensured that on the premise of structural behaviour, reduces cost to greatest extent, alleviates 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: optimize vulcanite and the structure of metal core, position and shape
Shape, when variator vibration can be avoided excessive, there is flex point in suspension static stiffness curve, makes Static stiffness curve exist
Non-linear section seamlessly transits, and improves damping effect and the NVH performance of car load；Optimize the structure of metal core,
While ensureing 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, the rubber bushing of a kind of automobile engine front mounting, mainly by annular gold
Belong to shell 2 and metal core 3 forms.In metal core 3 is centrally positioned in endless metal shell 2 and lead to
Over cure rubber 1 is fixed together with endless metal shell 2.Endless metal shell 2, metal core 3
Collectively constitute rubber bushing with vulcanite 1, be connected between subframe and variator, play damping
Effect.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 12.
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,
It is gradually increased towards left and right sides width.
Vulcanite 1 is main by " eight " word being supported between metal core 3 and endless metal shell 2
Shape part 11, the arch section 12 being positioned at metal core 3 top form.Arch section 12 and front-suspension
The axial line of support connecting hole 31 overlaps.The root of arch section 12 and the root of "eight" shape part 11
Portion is connected, and the left part of "eight" shape part 11 and right part are by the company bottom metal core 3
Connect part to be connected, thus in whole metal core 3 is wrapped in.
