Abstract
The utility model relates to a rubber sheath of an automobile universal joint, which comprises a main rubber sheath and an intermediate shaft sheath. The main rubber sheath includes a bottom end and a metal pressing plate which are connected, the intermediate shaft sheath is arranged at the upper end of the main rubber sheath and between the main rubber sheath and a steering shaft, the inner side of the intermediate shaft sheath corresponds to the appearance of the universal joint in size, the intermediate shaft sheath includes a metal framework connected to the upper end of the main rubber sheath, and a spherical hollow rubber body arranged outside the metal framework has an appearance of the shape of a corrugated pipe and comprises an upper fastener and a lower fastener which are connected. The rubber sheath of the automobile universal joint has the advantages of simple structure, low cost, and capabilities of enhancing protection function of a product and realizing the effects of shock absorption and sound insulation of the product under the condition of not changing assembly of the product.
Description
Technical field
The utility model relates to a kind of rubber sheath of automobile gimbal, relates in particular to the structure of this sheath.
Background technique
Along with the automobile industry high speed development, the regulation of the inside and outside noise abatement act rule of automobile, automobile ride, travelling comfort and power transmission system component coherence and people's requirement promotes day by day.
Rubber sheath of the prior art can't satisfy people to car load NVH performance requirement.As seen from Figure 1: metal platen 2 is assembled together with rubber sheath 1 by the locating stud 3 that rubber sheath 1 carries, the threshold pressing plate assembling of metal platen 2 and vehicle body, and rubber sheath 1 and steering shaft assembling play the effect of protection automobile gimbal.
And along with the raising of people to car load NVH performance requirement; only be that protection and protection universal joint are far from being enough; also to stop noise by noise source by rubber sheath to the interior of body transmission; if want to overcome this point; can only be with some shock-absorbing soundproof materials, and cost also can improve thereupon like this.
Summary of the invention
The utility model technical issues that need to address have provided a kind of rubber sheath of automobile gimbal, are intended to solve the above problems.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
The utility model comprises: the primary elastomeric sheath that bottom and metal platen are formed by connecting; Also comprise: inboard in primary elastomeric sheath upper end and between primary elastomeric sheath and steering shaft and the corresponding jack shaft sheath of universal joint boundary dimension; Described jack shaft sheath comprises: the metal frame that connects primary elastomeric sheath upper end; Being provided with outside described metal frame has adopted buckle to be connected the spherical hollow rubber body that profile is a corrugated tube shape with following buckle.
Compared with prior art, the beneficial effects of the utility model are: simple in structure, with low cost, do not changing under the product assembly condition, can improve the rubber sheath that the protective action of product own can satisfy product damping soundproof effect again.
Description of drawings
Fig. 1 is the structural representation that the rubber sheath of automobile gimbal in the prior art is connected with metal platen;
Fig. 2 is the utility model structural representation.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:
As seen from Figure 2: the utility model comprises: the primary elastomeric sheath 10 that bottom and metal platen 20 are formed by connecting; Also comprise: inboard in primary elastomeric sheath 10 upper ends and between primary elastomeric sheath 10 and steering shaft (not shown) and the corresponding jack shaft sheath of universal joint (not shown) boundary dimension; Described jack shaft sheath comprises: the metal frame 30 that connects primary elastomeric sheath 10 upper ends; Be provided with in described metal frame 30 outsides and adopted buckle 70 to be connected the spherical hollow rubber body 40 that profile is a corrugated tube shape with following buckle 60;
One first rubber 50 is set outside the buckle 70 on described; Outside the buckle 60 one second rubber 80 is set down described;
The described buckle 70 of going up is a plastic buckle with following buckle 60;
Intermediate sector's wall thickness of described rubber 40 is between 1.3mm-1.7mm.
The utility model is owing to adopted a jack shaft sheath between connection primary elastomeric sheath and steering shaft, it is the spherical hollow rubber body of corrugated tube shape that this jack shaft sheath has adopted upper and lower buckle to connect profile, and match with primary elastomeric sheath and steering shaft, corresponding with universal joint boundary dimension, the rubber body of sky in constituting, the wall thickness of jack shaft sheath is 1.3mm-1.7mm.The cavity that forms is converted into thermal dissipation in air with kinetic energy in the automobile driving process, weakened internal car noise greatly.
The utility model just increases a jack shaft sheath in steering shaft and the cooperation of former sheath than previous sheath on the basis of original primary elastomeric sheath, this sheath has good stretchability, elasticity, anti-circumnutate, endurance, and reduce maintenance, improve the life-span and use very convenient.
The utility model is satisfying under the product assembly condition, does not need to increase new material and satisfies people to the NVH performance requirement that rubber sheath proposes, and has guaranteed the original characteristic of product, has increased the effect of damping sound insulation.
Rubber bushing of the present utility model is all meeting the requirements of times of fatigue when the stand fatigue test after and phenomenon of rupture do not take place, in the NVH test, also play the very significantly effect of sound insulation and noise reduction.
