Description

Stabilizer bar bushing

Technical Field

The utility model relates to a stabilizer bar bush.

Background

Stabilizer bushings are the attachment for mounting stabilizer bars in automotive suspension systems and are typically molded from rubber vulcanization. During the use, stabilizer bar bush cover is on the body of rod of stabilizer bar to assemble on sub vehicle frame through the clamp. The stabilizer bar bush can play the effect such as support, location, buffering and noise reduction.

With the continuous emergence of new vehicle types, in order to realize certain functions of vehicles, through holes need to be formed in positions of auxiliary frames of some vehicles corresponding to stabilizer bar bushings, so that the supporting force of the stabilizer bar bushings is reduced, and when the vehicles shake violently, the stabilizer bar bushings made of rubber materials are easily sunk into the through holes, so that the rigidity of the existing stabilizer bar bushings cannot meet the use requirements. If a stiffer stabilizer bar bushing is manufactured using a harder rubber compound, the existing stabilizer bar bushing manufacturing process must be modified, which results in a significant cost increase.

Disclosure of Invention

The utility model aims to solve the technical problem that a stabilizer bar bush is provided, it has realized with lower cost when installing on opening the sub vehicle frame that has the through-hole with the corresponding position of bush, satisfies the rigidity requirement of stabilizer bar bush on whole car.

In order to solve the technical problem, the utility model discloses the technical scheme who takes is:

a stabilizer bar bushing includes a rubber bushing body and a metal base plate; the bottom of the rubber bushing body is provided with a plurality of buckling parts protruding downwards, the metal base plate is provided with a plurality of buckling holes matched with the buckling parts respectively, and each buckling part penetrates through the corresponding buckling hole and buckles the bottom surface of the metal base plate.

In the above-mentioned stabilizer bar bushing, the metal bottom plate is provided with a plurality of bolt holes for bolts to pass through.

The utility model discloses at least, have following advantage:

1. when the stabilizer bar bushing is arranged on the auxiliary frame which is provided with the through hole and corresponds to the bushing, the rigidity level of the traditional rubber stabilizer bar bushing arranged on the auxiliary frame without the through hole can be achieved by utilizing the supporting effect of the metal bottom plate, so that the rigidity requirement of the stabilizer bar bushing on the whole vehicle is met;

2. the rubber bushing body is connected with the metal bottom plate in a buckling mode, so that the installation is convenient, the connection is reliable, the stabilizer bar bushing of the embodiment can not fall off in the transportation process, and the transportation safety is improved;

3. the metal bottom plate is provided with a plurality of bolt holes, so that the stabilizer bar assembly is assembled on the auxiliary frame through bolts.

Detailed Description

The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

Fig. 1 to 3 show a structure of a stabilizer bar bushing according to an embodiment of the present invention. Referring to fig. 1 to 3, a stabilizer bar bushing according to an embodiment of the present invention includes a rubber bushing body 1 and a metal bottom plate 2.

The rubber bushing body 1 is formed by vulcanizing rubber. The rubber bushing body 1 is provided with a central through hole 10 for the stabilizer bar to pass through, and a notch 13 which is arranged along the axial length of the rubber bushing body 1 and penetrates through the central through hole 10 is further formed in the side surface of the rubber bushing body 1. The bottom of the rubber bushing body 1 is provided with two downwardly protruding buckling parts 11, the metal base plate 2 is provided with two buckling holes 21 respectively matched with the two buckling parts 11, and each buckling part 11 penetrates through the corresponding buckling hole 21 and buckles the bottom surface of the metal base plate 2.

In the present embodiment, each of the fastening portions 11 is composed of a column portion 111 and a cap portion 112, the cap portion 112 is connected to the top end of the column portion 111, the column portion 111 is inserted into the fastening hole 21, and the inner surface of the cap portion 112 fastens the bottom surface of the metal base plate 2. Alternatively, the cap 112 has an inverted truncated cone shape, and functions not only to fasten the metal base plate but also to guide the fastening part 11 through the fastening hole 21.

In other embodiments, the number of fastening portions 11 and fastening holes 21 can be three, four, etc.

The metal base plate 2 is provided with two bolt holes 22 through which bolts are passed so as to be assembled to the sub-frame by bolts. Fig. 4 shows a partial schematic view of the subframe 9 with through-holes 91 at positions corresponding to the stabilizer bar bushings. As shown in fig. 4, the subframe 9 has two bolt holes 92 opened at positions corresponding to the two bolt holes 22, respectively.

In this embodiment, the cap portions 112 of the plurality of engagement portions 11 of the rubber bushing body 1 extend into the through holes 91 of the subframe 9. The bolt holes 22 of the metal base plate 2 are elliptical holes. The elliptical hole is slightly larger than the bolt hole of the stabilizer bar clamp, so that the smooth passing performance of the bolt in a certain error range can be ensured, and the stabilizer bar assembly can be smoothly assembled on the auxiliary frame 9 of the whole vehicle. In other embodiments, the bolt holes 22 may be three, four, etc.

In the present embodiment, the metal base plate 2 is a flat metal plate. Preferably, the metal base plate 2 is an aluminum plate. The aluminum plate can meet the requirements of strength and corrosion resistance, and is low in cost.

When the stabilizer bar bushing of the embodiment is arranged on the auxiliary frame with the through holes at the positions corresponding to the bushings, the rigidity level of the traditional rubber stabilizer bar bushing (namely the rigidity of the rubber body under the plane support) when the stabilizer bar bushing is arranged on the auxiliary frame without the through holes can be achieved by utilizing the supporting effect of the metal bottom plate, so that the rigidity requirement of the stabilizer bar bushing on the whole vehicle is met.

It will be apparent to those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention. Thus, if such modifications and variations of the present invention fall within the scope of the claims and their equivalents, the present invention is also intended to include such modifications and variations.
