Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention is described in further detail with reference to the accompanying drawings and specific embodiments. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the invention to those skilled in the art.
As shown in fig. 1 to 3, the combined bushing provided by the present embodiment includes an outer frame 1, a first elastic member 2, an inner frame 3 and a second elastic member 4. The exoskeleton 1 has a through-hole 1 a. The first elastic element 2 circumferentially covers the outer wall of the outer frame 1. The second elastic member 4 circumferentially covers the inner frame 3. The end of the outer frame 1 is bent inward to form a bent end 1b, and the bent end 1b can be wrapped on the upper and lower end faces of the second elastic member 4, that is, the inner frame 3 can be fixedly disposed in the through hole 1a by the second elastic member 4.
In this embodiment, the outer frame 1 has a tubular structure, and the first elastic member 2 also has a tubular structure capable of covering the outer frame 1. The bent end 1b is formed at the end of the tubular exoskeleton 1, i.e., the exoskeleton 1 forms a cuff inward in the circumferential direction thereof at the end. The inner frame 3 is in a column shape, and the second elastic element 4 can be wrapped on the tubular structure of the inner frame 3.
Based on the above structure, the outer bobbin 1 may be designed in an arbitrary shape, and the inner bobbin 3 may also be designed in an arbitrary shape. It is only necessary that the second elastic member 4 be disposed in the through hole 1a of the outer frame 1 and fixed by the bent end 1 b. It will be appreciated by those skilled in the art that in this configuration, the materials of the first and second elastic members can be freely selected (and can be made of the same or different materials, for example, the first elastic member 2 is made of plastic, the second elastic member 4 is made of rubber, or both the first elastic sheet 2 and the second elastic member 4 are made of rubber). Therefore, the purposes of different compression or different strength, high damping or low damping and the like for different use requirements can be realized.
Further, in the present embodiment, the diameter of the second elastic member 4 and the diameter of the through hole 1a are substantially equivalent to each other, so that the outer frame 1 and the inner frame 3 can be clearance fitted with high precision by the thickness of the second elastic member 4.
The combined bushing can maximally absorb the vibration generated by bumping of vehicles with uneven road surfaces by utilizing the low torque performance of the combined bushing, and improves the driving comfort. In addition, the combined bushing improves the stress distribution state of the rubber elastic part, reduces the shearing stress and prolongs the service life of the elastic part (particularly the rubber part).
Further, the first elastic member 2 and the second elastic member 4 may be made of rubber having the same or different performance parameters. The first elastic member 2 and the outer wall of the exoskeleton 1 are vulcanized and molded through a rubber vulcanization process (using an existing rubber vulcanization process). The second elastic member 4 and the outer wall of the inner frame 3 are vulcanized and molded by a rubber vulcanization process.
The outer bobbin 1 and the inner bobbin 3 may be made of metal.
In this embodiment, the bent end 1b and the second elastic member 4 can be regarded as overlapping, so that the second elastic member 4 is fixed in the through hole 1 a. Furthermore, the bent end 1b and the second elastic member 4 can be fixedly connected to each other in a riveting manner (which may be a forward riveting or a reverse riveting).
In the present embodiment, as shown in fig. 3, a lubricating coating (self-lubricating) is applied to the portion where the second elastic member 4 and the exoskeleton 1 are attached to each other, and the lubricating coating may be teflon.
In another embodiment, as shown in fig. 4, the inner frame 3 of the composite bushing does not represent a single cylinder but adopts a more complicated structure, but the shape of the through-hole 1a of the outer frame 1 is not substantially changed, so that the inner frame 3 and the outer frame 1 can be coupled to each other by means of a second elastic member 4 corresponding to the shape of the through-hole 1 a. In the embodiment shown in fig. 4, the thickness of the second elastic element 4 is very thin, and the bending degree of the bending end 1b is smaller than that of the bending end 1b of the embodiment shown in fig. 1 to 3.
It will be understood by those skilled in the art that the shape of the through hole 1a of the outer bobbin 1 may be changed, and only the shape of the second elastic member 4 is changed accordingly, that is, it is sufficient that the second elastic member 4 can be disposed in the through hole 1a and fixed by the bent end 1b without changing the shape of the inner bobbin 3.
Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention and are not restrictive. Although the present invention has been described in detail with reference to the embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the present invention as defined by the appended claims.
