Abstract
The utility model relates to a damping component of an automobile, particularly the improvement of structures of an automobile front suspension system, a body top connection board assembly, etc. The utility model is arranged between a front suspension system and an automobile body. The utility model comprises main rubber, an upper gasket, a lower gasket and a support frame which is arranged at the periphery of the main rubber; the upper and the lower gaskets are fixedly arranged on the upper end and the lower end of the main rubber respectively by an inner tube which is arranged in the main rubber; the inner tube and the main rubber are in interference fit. The utility model solves the technical problems existing in the prior art that the fatigue life of parts is short, the evaluation for the NVH characteristics of the whole automobile is low, etc.
Description
Technical field
The utility model relates to a kind of damping part of automobile, especially relates to a kind of front overhang and hangs system and the isostructural improvement of vehicle body top connecting panel assembly.
Background technology
The top connecting panel is a damping part on the automobile, being installed on front suspension system unifies between the vehicle body, be mainly used to support and alleviate the impact of suspension to vehicle body, and play the effect of sound insulation aspect, the performance quality of this part will directly influence suspension and estimate at car load NVH.
From the material behavior of rubber, the steady component of stress state of material internal is to there being fatigue life of product considerable influence when running condition.When the material internal stress was tension, rubber was compared unstress state and sharply descend fatigue life, when material internal stress pressurized, compares unstress state the fatigue life of rubber and improves a lot.
Pipe is bonding for sulfuration with the connection structure of rubber in the prior art, in use, be subjected to the stress of tension with the rubber at interior pipe jointing place, the problem that exists junction rubber to be torn, make that the fatigue life of whole part is lower, in a complete car load fatigue life test cycle, this part need be changed 2 ~ 3 times, and top connecting panel assembly failure also frequently took place in the guarantee period of car, cause replacing.There is bigger problem in part aspect fatigue life, there is certain potential safety hazard in this part, and 0vehicle marketing is caused great influence, recalls as causing automobile thus, and consequence is more with hardly imaginable.
Primary elastomeric rigidity value when normal applying working condition is higher, causes the dynamic and static state performance of whole part not meet the demands fully, makes suspension relatively poor in the NVH of car load subjective assessment, product performance tuning aspect, particularly the high-frequency performance of product is relatively poor.
Summary of the invention
The utility model purpose provides a kind of rational in infrastructure, the fatigue life of product is longer, the front overhang that the evaluation aspect of car load NVH characteristic is enhanced is hung system and vehicle body top connecting panel assembly, the fatigue life that mainly is solution existing in prior technology part is shorter, the low technical matters that waits of the evaluation of the NVH characteristic of car load.
Above-mentioned technical matters of the present utility model is mainly solved by following technical proposals: be located at front suspension system and unify between the vehicle body, comprise primary elastomeric, upper gasket, lower gasket, be located at the support of primary elastomeric periphery, described upper gasket and lower gasket be respectively by being located at the top and bottom that interior pipe in the primary elastomeric is fixedly arranged on primary elastomeric, described in pipe and primary elastomeric interference fit.Because the connection structure of interior pipe and rubber bondingly changes interference into and is press-fitted by vulcanizing, so problem that does not exist junction rubber to be torn, the faying face of primary elastomeric and interior pipe is under the compression chord state when normal applying working condition, had the fatigue life of primary elastomeric largely and improved, be greatly improved the fatigue life of entire product.
As preferably, be provided with coaxial inner ring and outer ring on the described primary elastomeric, be provided with annular groove between described inner ring and outer ring; The height of described outer ring is higher than the height of inner ring.The part upper surface has adopted the double-layer rubber structure of inner ring and outer ring to make product when normal applying working condition lower rigidity value be arranged, and can guarantee the spacing requirement of product under big load working condition.By structure change, product has the high-frequency performance of great advantage, particularly product to be greatly improved in performance aspect tuning.
As preferably, the cone angle of described primary elastomeric lower end is 110 °-130 °; The cone angle of described rubber lower end is 115 °-125 °.
As preferably, be provided with interior iron ring in the described primary elastomeric, described primary elastomeric, interior iron ring and support sulfuration are one.
Therefore, the utlity model has rational in infrastructurely, the fatigue life of product is longer, the evaluation aspect of car load NVH characteristic characteristics such as be enhanced.Because the connection structure of interior pipe and rubber bondingly changes interference into and is press-fitted by vulcanizing, so problem that does not exist junction rubber to be torn, the faying face of primary elastomeric and interior pipe is under the compression chord state when normal applying working condition, had the fatigue life of primary elastomeric largely and improved, be greatly improved the fatigue life of entire product.The part upper surface has adopted the double-layer rubber structure of inner ring and outer ring to make product when normal applying working condition lower rigidity value be arranged, and can guarantee the spacing requirement of product under big load working condition.By structure change, product has the high-frequency performance of great advantage, particularly product to be greatly improved in performance aspect tuning.
