Abstract
A kind of buffer block for automotive suspension elastomer structure, it includes rubber elastomer, its technological points is: center is with the cylindrical polyurethane elastomer that through hole is installed, outer surface at cylindrical polyurethane elastomer is wave structure vertically, and this cylindrical polyurethane elastomer is near being taper structure on the position of one end; Also be enclosed with one deck plantation rubber annular elastomer structure in the inner side of the annular trough of wave structure body.The utility model, owing to adopting the composite structure of polyurethane elastomer and rubber elastomer bi-material, therefore, has the composite attribute of described two kinds of materials, and in the situation that quality reduces relatively, elastic effect increases, and resilient durability is improved; Particularly mention widely improvement in impact-absorbing load.The technological scheme providing by this structure can realize widens buffer stopper elastic characteristic scope, reduces again component cost.
Description
Technical field
The utility model relates to a kind of automotive suspension technical field, specifically a kind of buffer block for automotive suspension elastomer structure.
Background technique
Suspension buffer stopper is a part for suspension spring, and its Main Function, for the impact to vehicle body in buffering wheel hop process, for suspension provides additional rigidity (auxiliary spring), the limiting wheel stroke of beating, prevents that vehicle component from damaging.
Conventional buffer stopper outer surface is cylinder or cone shape, produces at work extrusion-deformation, and ensures elastic characteristic by buffer stopper material self character and profile, to play buffering, becomes rigidity and spacing effect.But the restriction that is subject in actual use, usage space, material self character and cost often can not be designed the desirable elastic characteristic needing.In the situation that ensureing elastic characteristic reluctantly, buffer stopper in use can produce the phenomenons such as cracking or height loss are serious after repeatedly pushing, and causes that vehicle uses problem.
What traditional buffer stopper generally adopted is homogenous material, and with regard to polyurethane material and rubber phase ratio, its advantage is: polyurethane material quality is little, is about 1/2 of rubber material; Polyurethane material distortion is large, has good non-linearly, and ordinary rubber buffer stopper compress variation is about 50% of free height, and cellular polyurethane material can reach 75%; Polyurethane material when carrying outside dimension changes little, and required radial dimension space is little; Cellular polyurethane buffer stopper is than rubber material impact-absorbing load better; But shortcoming is: cost of material is high; Under some applying working condition, durability is bad, and fatigue damage is large; After repeatedly large pressure compresses, be foam process due to what adopt, may there is height loss.
Summary of the invention
The purpose of this utility model is to provide a kind of buffer block for automotive suspension elastomer structure that adopts Blend materials
The purpose of this utility model is to realize like this, the utility model is by the following technical solutions: it includes rubber elastomer, it is characterized in that: center is with the cylindrical polyurethane elastomer that through hole is installed, outer surface at cylindrical polyurethane elastomer is wave structure vertically, and this cylindrical polyurethane elastomer is near being taper structure on the position of one end; Also be enclosed with one deck plantation rubber annular elastomer structure in the inner side of the annular trough of wave structure body.
Polyurethane, rubber are the common used materials of making suspension buffer stopper, and the characteristics different according to bi-material are also structurally used in conjunction with, and are ensureing, under the prerequisite of durability, to widen elastic characteristic using scope.The technical program proposed invention point or improvement are to change a kind of material to make buffer stopper be that bi-material is used in conjunction with, its structure is that conical elastomer is in parallel is assembled together by rubber ring elastomer and polyurethane, the technological scheme providing by this structure can realize widens buffer stopper elastic characteristic scope, reduces again component cost.
The utility model, owing to adopting the composite structure of polyurethane elastomer and rubber elastomer bi-material, therefore, has the composite attribute of described two kinds of materials, and in the situation that quality reduces relatively, elastic effect increases, and resilient durability is improved; Particularly mention widely improvement in impact-absorbing load.
The utility model also has simple and reasonable, easy to process, and cost is low, long service life, the feature such as application area is wide.
Brief description of the drawings
Fig. 1 is sectional structure simplified schematic diagram of the present utility model;
Fig. 2 is the utility model buffer stopper elastomeric resilient characteristic curve.
Below in conjunction with accompanying drawing and by example, the utility model is described in further detail; but following example is only the utility model example wherein; do not represent the rights protection scope that the utility model limits, rights protection scope of the present utility model is as the criterion with claims.
Embodiment
example 1
Shown in Fig. 1-2, in figure 1 is rubber elastomer, 2 is cellular polyurethane elastomer, center is with the cylindrical cellular polyurethane elastomer 2 that through hole is installed, outer surface at cylindrical polyurethane elastomer is wave structure 3 vertically, and this cylindrical polyurethane elastomer is near being taper structure 4 on the position of one end; Also be enclosed with one deck plantation rubber annular elastomer 1 in the inner side of the annular trough 5 of wave structure body.
The N representative pressure unit of Y-axis in Fig. 2, and X-axis represents resiliently deformable distance.
The buffer stopper of this structure is in fact the elastic element that a kind of nonlinear degree is very strong, in parallel with main elastic element, is used for limiting suspension travel, prevents that suspension from puncturing, and absorbs and passes to the impulsive load vehicle body from wheel.Its material adopting, except rubber, also has cellular polyurethane.
Working principle is as follows:
Vehicle suspension is in the time slightly beating, and polyurethane Elastic Cylindrical body works, and can bring into play polyurethane distortion large, has good non-linearly, and the advantage that absorbing is good improves travelling comfort within the scope of very large suspension travel.In the time that suspension runs into large impact, when polyurethane Elastic Cylindrical body is compressed to certain altitude, rubber elastomer works, and ensures spacing height.And can, by the design of polyurethane Elastic Cylindrical body and rubber elastomer size, obtain the elastic characteristic of wishing.
