Description
Technical Field
The utility model relates to a rubber main spring structure, in particular to a rubber main spring for suspending an automobile power assembly.
Background
The rubber main spring is one of the main structures constituting the hydraulic bushing of the sub-frame for the automobile, and referring to fig. 1, the rubber main spring is generally composed of an inner frame 21', rubber 22' and a metal jacket 23 '. With the implementation of the 'double carbon' target in China, the vehicle enterprise puts forward higher light-weight requirements on vehicle parts in order to meet the stringent requirements of environmental protection and laws and regulations. Rubber bushings have also begun to use lightweight fiber reinforced composites. In order to provide a rubber main spring with a good fatigue life, the conventional main spring structure needs to be subjected to a diameter reduction treatment to release the tensile residual stress generated when the rubber is vulcanized. When the rubber bushing begins to use the composite material, the diameter reduction process not only brings about an increase in processing cost, but also can permanently damage the brittle composite material, so that the product is defective.
Disclosure of Invention
The utility model aims to overcome the defects of the prior art, and provides the rubber main spring for the suspension of the automobile power assembly, which does not need to shrink during installation, thereby reducing the process cost; can be used in resin matrix composite bushings, and has the characteristics of low cost, easy installation and the like.
The technical scheme for achieving the purpose is as follows: the rubber main spring for suspending the automobile power assembly consists of an inner framework, rubber and a plurality of metal reinforcing sheets, wherein the rubber consists of a rubber sleeve and a plurality of rubber strips uniformly distributed on the outer circumferential surface of the rubber sleeve, the inner circumferential surface of the rubber sleeve is adhered to the outer circumferential surface of the inner framework, and each rubber strip forms a free end of the rubber; each metal reinforcing sheet is arc-shaped, the plurality of metal reinforcing sheets are arranged along the same circumference, and the inner arc surfaces of the plurality of metal reinforcing sheets are connected with the outer ends of the plurality of rubber strips in one-to-one correspondence.
The rubber main spring for suspending the automobile power assembly, wherein each metal reinforcing sheet is wrapped with a damping rubber layer except the upper end face and the lower end face.
The rubber main spring for suspending the automobile power assembly is characterized in that the number of the rubber strips and the number of the metal reinforcing sheets are four.
The rubber main spring for suspending the automobile power assembly does not need to be reduced in diameter during installation, so that the process cost is reduced; can be used in resin matrix composite bushings, and has the characteristics of low cost, easy installation and the like.

Detailed Description
In order to enable those skilled in the art to better understand the technical scheme of the present utility model, the following detailed description is provided with reference to the accompanying drawings:
referring to fig. 2, 3 and 4, a rubber main spring for a suspension of an automobile power assembly according to a preferred embodiment of the present utility model is composed of an inner frame 21, a rubber 22 and a plurality of metal reinforcing sheets 23, the rubber 22 is composed of a rubber sleeve 221 and four rubber strips 222 uniformly distributed on the outer circumferential surface thereof, the inner circumferential surface of the rubber sleeve 221 is adhered to the outer circumferential surface of the inner frame 21, each rubber strip 222 forms a free end of the rubber 22, and each rubber strip 222 is gradually smaller in width from outside to inside; each metal reinforcing sheet 23 is arc-shaped, the four metal reinforcing sheets 23 are arranged along the same circumference, and the inner arc surfaces of the four metal reinforcing sheets 23 are connected with the outer ends of the four rubber strips 222 in a one-to-one correspondence manner. The free end (rubber strip) of the outer side of the rubber 22 can be conveniently clamped into the bushing due to the reinforcing effect of the metal reinforcing sheet 23, and the rubber is characterized by convenient installation.
Each metal reinforcing plate 23 is wrapped with a damping rubber layer 231 except for the upper end face and the lower end face, namely, the inner arc face, the outer arc face and the two side faces of each metal reinforcing plate 23 are wrapped with damping rubber layers, and when the metal reinforcing plate 23 of the rubber main spring is connected with other parts, the damping rubber layers 231 can play a role in damping and reducing noise.
The rubber main spring for suspending the automobile power assembly disclosed by the utility model has the advantages that the metal jacket of the existing rubber main spring is eliminated, the inner side of the rubber is bonded with the surface of the inner framework, the outer side of the rubber is a free end, and the free end can be freely deformed in the cooling stage of a high-temperature vulcanization process, so that residual stress is not generated, and the diameter of the rubber main spring does not need to be reduced.
In conclusion, the rubber main spring for the suspension of the automobile power assembly does not need to be reduced in diameter during installation, so that the process cost is reduced; can be used in resin matrix composite bushings, and has the characteristics of low cost, easy installation and the like.
It will be appreciated by persons skilled in the art that the above embodiments are provided for illustration only and not for limitation of the utility model, and that variations and modifications of the above described embodiments are intended to fall within the scope of the claims of the utility model as long as they fall within the true spirit of the utility model.
