Referring to fig. 1 and 2, the stabilizer bushing 10 of the present embodiment is a ring-shaped structure as a whole, and is installed in the stabilizer clamp 20, and the stabilizer bushing 10 includes two semicircular ring-shaped bushing structures 11, that is, the radial cross section of the bushing structure 11 is a circular arc. The two bushing structures 11 are snapped back together, wherein a first end 8 of one bushing structure 11 in the circumferential direction is connected to a first end 8 of the other bushing structure 11 in the circumferential direction by means of the elastic element 6, so that an accommodation space 12 for accommodating a stabilizer bar (not shown in the figures) is formed between the two bushing structures 11. The shapes of the two bushing structures 11 may be the same or different, as long as the two bushing structures 11 are assembled together to form the accommodating space 12 for placing the stabilizer bar. The elastic element 6 may be made of a rubber material, and the two bushing structures 11 are vulcanized together by rubber. The elastic element 6 may also be of a spring or the like construction, as long as it is ensured that an opening 7 can be opened between the two bushing constructions 11 for mounting the stabilizer bar bushing 10 to the stabilizer bar, which is not particularly limited herein.
With continued reference to fig. 1, the bushing structure 11 includes an outer layer rubber 1, a first metal skeleton 2 and a middle layer rubber 3, which are distributed in this order from inside to outside in the radial direction thereof. The first metal framework 2 is a semicircular ring structure. The first metal framework 2 should be made of hard metal material, and is not limited in detail here because of the variety. The outer rubber 1 is disposed on the outer side of the first metal framework 2 far away from the accommodating space 12, that is, the outer rubber is disposed on the radial outer side of the first metal framework. The middle layer rubber 3 is disposed on the inner side of the first metal framework 2 close to the accommodating space 12, that is, the middle layer rubber is disposed on the radial inner side of the first metal framework. The outer layer rubber 1 and the middle layer rubber 3 can be made of pure rubber materials, and can also be made of pure polyurethane materials or other flexible rubber structures.
With the above structure, one end of the two bushing structures 11 is connected through the elastic element 6, and under the external force, the two bushing structures 11 can open one opening 7, mount the stabilizer bar bushing 10 on the stabilizer bar through the opening 7, and then clamp the stabilizer bar clamp 20 outside the stabilizer bar bushing 10 to fix the stabilizer bar on the axle or other positions of the vehicle. Bushing structure 11 adopts three-layer construction, and the centre is first metal framework 2, and inside and outside both sides are middle level rubber 3 and outer rubber 1 respectively, and this structure can effectively improve the rigidity of stabilizer bar gum cover to improve the life of stabilizer bar gum cover.
With continued reference to fig. 1, since the bushing structure 11 with the three-layer structure may have problems such as weak adhesion or even detachment of metal and rubber during the limit use of the stabilizer bar, therefore, in a further embodiment, the bushing structure 11 is configured as a five-layer structure, the bushing structure 11 further includes, in addition to the three-layer structure, a second metal framework 4 disposed inside the middle rubber 3 close to the accommodating space 12, and an inner rubber 5 disposed inside the second metal framework 4 close to the accommodating space 12, that is, the second metal framework 4 is disposed radially inside the middle rubber 3, and the bushing structure 11 of this embodiment, in which the inner rubber 5 is disposed radially inside the second metal framework 4, includes an outer rubber 1, a first metal framework 2, the middle rubber 3, the second metal framework 4, and the inner rubber 5, which are sequentially disposed from outside to inside. The outer layer rubber 1, the first metal framework 2, the middle layer rubber 3, the second metal framework 4 and the inner layer rubber 5 are vulcanized and formed. The five-layer structure is adopted, so that the force transmission path can be prolonged, the problem that the bonding between the metal framework and the rubber layer is not firm or separated due to long-time use is effectively solved, and the service life is further prolonged.
Further, the thickness of the first metal framework 2 is larger than that of the second metal framework 4. Because the second metal framework 4 is closer to the stabilizer bar, if the thickness of the second metal framework is larger, the force generated by the stabilizer bar cannot be effectively transmitted to the first metal framework 2, so that the second metal framework 4 and the rubber layer connected with the second metal framework are stressed greatly, the connection between the second metal framework and the rubber layer is damaged, and the second metal framework and the rubber layer are infirm, therefore, the thickness of the second metal framework 4 is thinner, namely, the second metal framework can bear part of the force, and other forces can be transmitted to the thicker first metal framework 2, so that the whole service life of the stabilizer bar bushing 10 is prolonged.
With continued reference to fig. 1, in a further embodiment, wherein the second end 9 of one bushing arrangement 11 in the circumferential direction is spaced apart from the second end 9 of the other bushing arrangement 11 in the circumferential direction to define an opening 7 between the two second ends. The opening 7 should not be too large, and preferably should not exceed the stabilizer radius, so as to facilitate the installation of the stabilizer bushing 10 and increase the bearing area of the stabilizer bushing 10.
With continued reference to fig. 1, in a further embodiment, to prevent the stabilizer bushing 10 from creating a relative position with the stabilizer clamp 20 during vehicle movement, the useful life of the stabilizer bushing 10 is affected. The outer surface of the outer rubber layer 1 away from the accommodating space 12 is provided with a plurality of protrusions 13 matched with the stabilizer bar clamping blocks 20. Further, the protrusion 13 extends in the circumferential direction of the stabilizer bar bushing 10, and can be effectively prevented from moving in the axial direction. Specifically, the number of the protrusions 13 is not too large, which increases the cost, and the number is set to about 3.
With continued reference to fig. 1, in a further embodiment, the length of the first metal skeleton 2 in the axial direction of the stabilizer bar bushing 10 is equal to the length of the second metal skeleton 4 in the axial direction of the stabilizer bar bushing 10; the length of the first metal skeleton 2 in the axial direction of the stabilizer bushing 10 is greater than the lengths of the outer layer rubber 1, the middle layer rubber 3, and the inner layer rubber 5 in the axial direction of the stabilizer bushing 10. With the above structure, the volume of the stabilizer bushing 10 can be effectively reduced.
The utility model also provides a vehicle, the vehicle is provided with the stabilizer bar, and the stabilizer bar passes through stabilizer bar clamp splice 20 to be installed in the axle, and wherein, set up the stabilizer bar bush 10 in any one of the above-mentioned embodiments between stabilizer bar and the stabilizer bar clamp splice 20. The structure of the stabilizer bushing 10 will not be described in detail here.
Thus, it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the invention have been shown and described in detail herein, many other variations and modifications can be made, consistent with the principles of the invention, which are directly determined or derived from the disclosure herein, without departing from the spirit and scope of the invention.
