Abstract
The utility model relates to a conical rubber sleeve which comprises a shock absorber elastomer and an inner connecting sleeve. The conical rubber sleeve is characterized in that the shock absorber elastomer is made of compound vulcanized rubber, the inner connecting sleeve is made of enhanced nylon, outer diameters of both ends of the inner connecting sleeve are enlarged to form bosses, and an oil storage tank is arranged in the middle of an inner hole of the inner connecting sleeve. Compared with the prior art, the conical rubber sleeve disclosed by the utility model has the advantages that the deformation resisting capability is increased, the production time per piece is shortened from 0.5 hours to 0.3 hours, the reject ratio is reduced from 1.2% to 0.4%, the whole service life is prolonged by 10% to 25%, the weight is reduced from 0.185 kg to 0.094 kg, and the integral benefit is good.
Description
Technical field
The utility model belongs to the auto parts machinery field, particularly a kind of tapered gum cover.
Background technique
Tapered gum cover mainly is to be used in the back balance suspension arrangement of heavy truck.Domestic existing tapered gum cover is comprised of with the interior steel bushing that is connected damping elastomer (polyurethane), sees Fig. 1.Existing tapered gum cover exists:
1, the polyurethane polyurethane that particularly hardness is larger has stronger buffer capacity, be suitable for absorbing the low frequency that is passed to vehicle body by the road surface and significantly shake, but durability is relatively poor.Be unfavorable for upper frequency that polyurethane absorbs and vibrations by a small margin because vehicle will inevitably produce in motion, make polyurethane damping elastomer can't reach desirable damping effect.
2, interior connection steel bushing shock absorption is relatively poor, and wear-resisting property is also unsatisfactory, and polyurethane damping elastomer does not also reach Endurance limit often in the middle of actual using process, and interior connection steel bushing just deformed damaged or concentrated wear is serious.
3, the manufacturing procedure of interior connection steel bushing is more, and dimensional accuracy and the surface roughness of its endoporus are had relatively high expectations, and be larger to latheman's technology dependence, and cost is relatively high.
Summary of the invention
Key in herein summary of the invention and describe paragraph.The purpose of this utility model is: provide a kind of tapered gum cover, the purpose that by structure optimization, reach its intensity of raising, increase its working life, comprehensive benefit is good.
The purpose of this utility model realizes by following approach:
A kind of tapered gum cover comprises damping elastomer and interior connecting sleeve, and its structural feature is: the damping elastomer is composite sulfuration rubber, and interior connecting sleeve is reinforced nylon, and the two ends external diameter of interior connecting sleeve strengthens and forms boss, and the centre of interior connecting sleeve endoporus is provided with oil storage tank.
The elastomeric composite sulfuration rubber of a kind of its damping of tapered gum cover of the present utility model, polyurethane has preferably shock absorption and durability relatively; Interior connecting sleeve is reinforced nylon, and its toughness, wear resistance, resistance to deformation intensity all are better than steel; Successively with the part of interior connecting sleeve two ends assemblings because the boss structure at interior connecting sleeve two ends has strengthened stressed area of contact each other, alleviated wearing and tearing and distortion each other; Its material of interior connecting sleeve itself just has self-lubricating function and adds the oil storage tank that arranges in the middle of the interior connecting sleeve endoporus, has alleviated interior connecting sleeve and the with it wearing and tearing of the axle of assembling, has prolonged interior connecting sleeve and the working life of the axle that assembles with it; Interior connecting sleeve guarantees not only that by the injection moulding straight forming dimensional accuracy of its endoporus and surface roughness satisfy usage requirement, and manufacturing efficiency also significantly improves.
The utility model is compared with the existing product technology, has the following advantages:
1, improved the non-deformability of tapered gum cover;
2, shorten the manufacture cycle of tapered gum cover, improved quality of product.Production time per piece shortened to 0.3 hour by original 0.5 hour, and reject ratio is reduced to existing 0.4% by original 1.2%;
3, test data shows that the whole service life of tapered gum cover improves 10%～25%;
4, the weight of tapered gum cover reduces to 0.094kg by original 0.185kg.

Embodiment
Below in conjunction with embodiment the utility model is described in more detail.
A kind of tapered gum cover as shown in Figure 2, comprise damping elastomer 3 and interior connecting sleeve 4, its structural feature is: damping elastomer 3 is composite sulfuration rubber, and interior connecting sleeve 4 is reinforced nylon, the two ends external diameter of interior connecting sleeve 4 strengthens and forms boss 5, and the centre of interior connecting sleeve 4 endoporus is provided with oil storage tank 6.
The composite sulfuration rubber of a kind of its damping elastomer 3 of tapered gum cover of the present utility model, polyurethane has preferably shock absorption and durability relatively; Interior connecting sleeve 4 is reinforced nylon, and its toughness, wear resistance, resistance to deformation intensity all are better than steel; Successively with the part of interior connecting sleeve 4 two ends assemblings because boss 5 structures at interior connecting sleeve 4 two ends have strengthened stressed area of contact each other, alleviated wearing and tearing and distortion each other; Interior connecting sleeve 4 its materials itself just have self-lubricating function and add the oil storage tank 6 that arranges in the middle of interior connecting sleeve 4 endoporus, have alleviated interior connecting sleeve 4 and the with it wearing and tearing of the axle of assembling, have prolonged interior connecting sleeve 4 and the working life of the axle that assembles with it; Interior connecting sleeve 4 guarantees not only that by the injection moulding straight forming dimensional accuracy of its endoporus and surface roughness satisfy usage requirement, and manufacturing efficiency also significantly improves.
