Abstract
The invention discloses a suspended shock absorbing bushing prepared from a novel material. The suspended shock absorbing bushing comprises an inner metal framework, an outer framework and a middle elastic layer. The middle elastic layer is arranged between the inner metal framework and the outer framework and is fixedly connected with the inner metal framework and the outer framework. The middle elastic layer is made of polyurethane. The suspended shock absorbing bushing overcomes the defects in the prior art, the main bottleneck of the shock absorbing bushing is the service life of an elastic material, a polyurethane material better in engineering performance is used for preparing the elastic material, so that the service life is prolonged and stability is improved. The polyurethane is better than natural rubber in the aspects of temperature stability and the wear resistance performance, and experiment results show that the service life of a shock absorber can be prolonged by two times or smaller.
Description
Technical field
The present invention relates to technical field of automobile, be specifically related to a kind of new material and hang class shock absorbing bushing.
Background technique
Along with the development of science and technology, people propose more and more higher requirement to the riding comfort of automobile and control stability, automobile suspension system directly affects the smoothness of vehicle, due to rubber material itself have that quality is light, shock resistance and the easy advantage such as absorbing high-frequency vibration, add that the adhesive technology of rubber and metal improves, the rubber bushing that metal and building rubber compound get up is widely used in the support device in automobile hanging.Its working principle is the high damping utilizing rubber material, and when shock absorbing bushing is given a shock and impact, part kinetic transformation when impacting can be that thermal energy consumption is fallen by the vulcanized rubber elements playing buffer function, thus realizes the performance of damping noise reduction.Certainly, this just requires that vulcanized rubber material has good heat-proof aging and dynamic fatigue property.Natural rubber poor heat resistance is very easily aging.When after natural rubber quick aging, cause the road feel of vehicle comparatively fuzzy, and reaction when car turns to suddenly and runs into uneven road surface is more blunt, even occurs chassis abnormal sound.During vehicle travels, shock absorbing bushing will be subject to the effect of various external force, and there is the motive powers such as extruding, friction, torsional buckling between rubber and metal, natural gum weather resisteant is poor in addition, and product is short for working life, need make regular check on and change.
Summary of the invention
For the deficiencies in the prior art, the invention provides a kind of new material and hang class shock absorbing bushing, overcome the deficiencies in the prior art, the Main Bottleneck of shock absorbing bushing is the life-span of resilient materials, the polyurethane material using engineering property better makes resilient materials, to promote life-span and stability; Polyurethane temperature stability and wear resistance aspect all better than natural rubber, test result can extend the vibration damper life-span and reach less than 2 times.
Technical problem to be solved by this invention can be come to be realize by the following technical programs:
A kind of new material hangs class shock absorbing bushing, and comprise interior metal frame, purchasing ore and center elastomeric layer, described center elastomeric layer is arranged between interior metal frame and purchasing ore, and is fixedly connected with, and described center elastomeric layer is polyurethane.
Described interior metal frame, purchasing ore and polyurethane are integrated by being sulfided into.
Compared with prior art, beneficial effect of the present invention is:
The polyurethane material that the present invention uses engineering property better makes resilient materials, to promote life-span and stability; Polyurethane temperature stability and wear resistance aspect all better than natural rubber, test result can extend the vibration damper life-span and reach less than 2 times; In addition according to the change of formula rate, the product of different hardness can also be produced, with the driving style of the car owner that fits; The traveling texture of entire vehicle is more sturdy, and the reaction that vehicle body changes for road surface is very sharp, makes driver can grasp more running information.Unexpected modified line during high speed, also without blunt sense in the past, feels very good; Part replacement is simple, quick.Because the lining that natural rubber is general is all that interference is installed, therefore needs instrument to help when dismounting, can the regular hour be spent; Damping performance obviously promotes, and reduces the noise in vehicle traveling.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
For making the object of the embodiment of the present invention, technological scheme and advantage clearly, below in conjunction with the embodiment of the present invention, the technological scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
A kind of new material hangs class shock absorbing bushing, comprise interior metal frame 3, purchasing ore 1 and center elastomeric layer 2, described center elastomeric layer is arranged between interior metal frame and purchasing ore, and be fixedly connected with, described center elastomeric layer is polyurethane, and described interior metal frame, purchasing ore and polyurethane are integrated by being sulfided into; Polyurethane material makes resilient materials, to promote life-span and stability; Polyurethane temperature stability and wear resistance aspect all better than natural rubber, test result can extend the vibration damper life-span and reach less than 2 times; In addition according to the change of formula rate, the product of different hardness can also be produced, with the driving style of the car owner that fits; The traveling texture of entire vehicle is more sturdy, and the reaction that vehicle body changes for road surface is very sharp, makes driver can grasp more running information.Unexpected modified line during high speed, also without blunt sense in the past, feels very good; Part replacement is simple, quick.Because the lining that natural rubber is general is all that interference is installed, therefore needs instrument to help when dismounting, can the regular hour be spent; Damping performance obviously promotes, and reduces the noise in vehicle traveling.
It should be noted that, in this article, such as term " comprises ", " comprising " or its any other variant are intended to contain comprising of nonexcludability, thus make to comprise the process of a series of key element, method, article or equipment and not only comprise those key elements, but also comprise other key elements clearly do not listed, or also comprise by the intrinsic key element of this process, method, article or equipment.When not more restrictions, the key element limited by statement " comprising ... ", and be not precluded within process, method, article or the equipment comprising described key element and also there is other identical element.
Above embodiment only in order to technological scheme of the present invention to be described, is not intended to limit; Although with reference to previous embodiment to invention has been detailed description, those of ordinary skill in the art is to be understood that: it still can be modified to the technological scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature; And these amendments or replacement, do not make the essence of appropriate technical solution depart from the spirit and scope of various embodiments of the present invention technological scheme.
