Description
Technical field
This utility model relates to car engine suspension component structural, is specifically related to a kind of for electromotor
The rubber bush structure of front-suspension.
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 now structure exists is: the structure design of rubber bushing is unreasonable, rubber bushing with
Front-suspension bracket rigid contact, easily there is flex point in suspension static rigidity curve, 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, reduces and manufactures and design cost,
Avoid suspension static rigidity curve that flex point occurs, improve effectiveness in vibration suppression and the NVH performance of car load.
To this end, the technical scheme that this utility model is used is: a kind of engine front mounting rubber bushing,
Including endless metal shell and metal core, described metal core is centrally positioned in endless metal shell also
Being fixed together by vulcanite sulfuration, before and after described endless metal shell, both sides are respectively provided with one
Vibration isolator, described vibration isolator is provided with the louvre that cincture endless metal housing axis is the most uniform,
And the distance of louvre distance annular metal shell axis is less than the internal diameter of endless metal shell, vibration isolator
External diameter is more than the external diameter of endless metal shell, and described metal core two ends passes through little shaft part through correspondence
Outside vibration isolator；
Described metal core is made up of the little shaft part of middle big shaft part and two ends, and big shaft part is wide at the top and narrow at the bottom,
Waist is centrally located the front-suspension bracket connecting hole of through little shaft part, on big shaft part top between left and right every setting
It is equipped with two the first lightening holes, about big shaft part bottom, is arranged at intervals with two the second lightening holes, described
Vulcanite includes the "eight" shape part being supported between metal core and endless metal shell, 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 described arch section is connected with the root of "eight" shape part, the left side of "eight" shape part
Divide and be connected by the coupling part bottom metal core with right part, thus whole metal core is wrapped up
Including.
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, and before and after endless metal shell, vibration isolator is set up in both sides, and rubber bushing can be avoided to prop up with front-suspension
When frame rigid contact and variator vibration are excessive, there is flex point in suspension static stiffness curve, makes Static stiffness bent
Line seamlessly transits at non-linear section, improves damping effect and the NVH performance of car load；And 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 the state that this utility model takes off vibration isolator.
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 engine front mounting rubber bushing, mainly by endless metal outside
Shell 1, metal core 3 and vibration isolator 4 form.Metal core 3 is centrally positioned in endless metal shell 1
In and by vulcanite 2 vulcanize be fixed together.
Before and after endless metal shell 1, both sides are respectively provided with a vibration isolator 4, and vibration isolator 4 is provided with ring
Around the louvre 41 that endless metal shell 1 axis is the most uniform.Louvre 41 is apart from annular metal shell
The distance of 1 axis is more than endless metal shell less than the internal diameter of endless metal shell 1, the external diameter of vibration isolator 4
The external diameter of 1, to ensure that the louvre 41 on vibration isolator 4 effectively dispels the heat for vulcanite 2, avoids simultaneously
Rubber bushing and front-suspension bracket rigid contact.Metal core 3 two ends passes through little shaft part through correspondence
Outside vibration isolator 4.
Metal core 3 is made up of the little shaft part of middle big shaft part and two ends, and big shaft part is wide at the top and narrow at the bottom,
Waist is centrally located the front-suspension bracket connecting hole 31 of through little shaft part, on big shaft part top between left and right every
It is provided with two the first lightening holes 32, about big shaft part bottom, is arranged at intervals with two the second lightening holes 33.
Vulcanite 2 includes the "eight" shape being supported between metal core 3 and endless metal shell 1
Part 21, it is positioned at the arch section 22 at metal core 3 top.Arch section 22 is with front-suspension bracket even
The axial line connecing hole 31 overlaps, and the root of arch section 22 is connected with the root of "eight" shape part 21,
The left part of "eight" shape part 21 and right part are by the connecting portion split-phase bottom metal core 3
Even, in thus whole metal core 3 being wrapped in.
Preferably, the cross section of the first lightening hole 32 is right-angled trapezium, the cross section of the second lightening hole 33
For right angled triangle, and the cross-sectional area of the first lightening hole 32 is more than the cross-sectional area of the second lightening hole 33.
It addition, that side width minimum that two the first lightening holes 32 are relative, towards left and right sides width gradually
Increase；That side width minimum that two the second lightening holes 33 are relative, is gradually increased towards left and right sides width.
