Description

Technical Field

[0001] The utility model specifically relates to a stabilizer bar bushing based on a special-shaped frame. Background Art

[0002] Compared with traditional fuel vehicles, new energy vehicles have more powerful, more comfortable, larger space, and more environmentally friendly advantages, and their market share will grow year by year. Due to the characteristics of heavy weight and high torque of the vehicle, the size of the stabilizer bar will be thicker. Therefore, under the same performance requirements, the design space of the stabilizer bar bushing is more compact. Most existing bushings are straight-cylindrical with a relatively simple structure. In a small space, it is difficult to meet the requirements of good stiffness performance, that is, the main direction static stiffness is large and the torsional stiffness is low enough. For this reason, we propose a stabilizer bar bushing based on a special-shaped skeleton. Utility Model Content

[0003] The utility model aims to provide a stabilizer bar bushing based on a special-shaped frame to solve the problem of low stiffness performance and poor torsional stiffness of the existing bushing when used in a small space range as mentioned in the background technology.

[0004] To achieve the above purpose, the utility model provides the following technical solution: a stabilizer bar bushing based on a special-shaped frame, comprising:

[0005] A first rubber sleeve and a second rubber sleeve arranged side by side with the first rubber sleeve, wherein a hole for the stabilizing rod to pass through is formed between the first rubber sleeve and the second rubber sleeve;

[0006] At least two honeycomb skeleton bodies are respectively arranged inside the first rubber sleeve and the second rubber sleeve;

[0007] The honeycomb ribs are integrally formed on the outer surface of the honeycomb frame body.

[0008] Preferably, both end surfaces of the second rubber sleeve are provided with first grooves avoiding the external bracket.

[0009] Preferably, two ends of the honeycomb skeleton body are provided with second grooves, and the second grooves correspond to the first grooves.

[0010] Preferably, the honeycomb ribs include transverse ribs and vertical ribs, the transverse ribs are distributed along the circumference of the honeycomb skeleton body, and the vertical ribs intersect with the transverse ribs and are perpendicular to each other.

[0011] Preferably, a through hole is formed through the inner side of the honeycomb skeleton body.

[0012] Preferably, both ends of the honeycomb skeleton body protrude upwards and intersect with the honeycomb ribs to form a plane body, and the plane bodies of the two honeycomb skeleton bodies are parallel to each other.

[0013] Preferably, the honeycomb skeleton body is made of plastic, and the first rubber sleeve and the second rubber sleeve are both made of natural rubber NR.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] This patent uses the honeycomb skeleton body and honeycomb ribs to increase the contact area with the external stabilizer bar and clamp, reduce local large stress concentration, and meet the stiffness requirements. Compared with conventional stabilizer bar bushings, under the same performance requirements, the bushing has a smaller size through the unique special-shaped honeycomb skeleton design, which is convenient for application and installation on stabilizer bars of various models in small spaces. The skeleton of the honeycomb structure can effectively strengthen the strength of the plastic itself, increase the static stiffness in the main direction, and reduce the torsional stiffness, thereby achieving the purpose of high stiffness and low torsion. In addition, because the honeycomb structure has a uniform plastic skeleton wall thickness, the heat transfer during vulcanization production will be better. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-Figure 4 The utility model provides a technical solution: a stabilizer bar bushing based on a special-shaped frame, comprising:

[0023] A first rubber sleeve 1 and a second rubber sleeve 2 arranged side by side with the first rubber sleeve 1, and a hole for the stabilizing rod to pass through is formed between the first rubber sleeve 1 and the second rubber sleeve 2;

[0024] At least two honeycomb skeleton bodies 4 are respectively arranged inside the first rubber sleeve 1 and the second rubber sleeve 2, so as to avoid the poor rigidity effect provided by the traditional straight-cylindrical bushing, which cannot be installed and used in a small space. Compared with the traditional stabilizer bar bushing structure, this bushing contains two pieces of special-shaped embedded special-shaped honeycomb skeleton bodies 4. In order to facilitate assembly and segmented production, in actual production, the thickness of the main force-bearing area of ​​the special-shaped honeycomb skeleton body 4 made of plastic material changes with the change of the stabilizer bar wire diameter.

[0025] The honeycomb ribs 5 are integrally formed on the outer surface of the honeycomb skeleton body 4 to provide better skeleton strength and increase the contact area with the external clamps and stabilizer bars, thereby achieving better uniform force distribution.

[0026] In this embodiment, preferably, first grooves 3 are formed on both end surfaces of the second rubber sleeve 2 to avoid the external bracket, so as to avoid collision with the external metal bracket causing large displacement.

[0027] In this embodiment, preferably, second grooves 7 are formed at both ends of the honeycomb skeleton body 4 , and the second grooves 7 correspond to the first grooves 3 .

[0028] In this embodiment, preferably, the honeycomb rib portion 5 includes transverse ribs 51 and vertical ribs 52. The transverse ribs 51 are distributed circumferentially along the honeycomb skeleton body 4. The vertical ribs 52 intersect with the transverse ribs 51 and are perpendicular to each other, so as to provide better strength for the special-shaped honeycomb skeleton body 4, increase the contact area with the rubber sleeve, and ensure uniform force during use.

[0029] In this embodiment, preferably, a through hole 6 is opened through the inner side of the honeycomb skeleton body 4 to facilitate production and ensure smooth flow of rubber during the production process, so that the first rubber sleeve 1 and the second rubber sleeve 2 can be better connected and fixed to the special-shaped honeycomb skeleton body 4.

[0030] In this embodiment, preferably, both ends of the honeycomb skeleton body 4 protrude upward and intersect with the honeycomb ribs 5 to form a plane body 8, and the plane bodies 8 of the two honeycomb skeleton bodies 4 are parallel to each other, so as to facilitate the alignment of the ends of the first rubber sleeve 1 and the second rubber sleeve 2 and to be mounted on the outside of the stabilizer bar.

[0031] In the present embodiment, preferably, the honeycomb skeleton body 4 is made of plastic, and the plastic is composed of PA66 and GF35, so as to enhance the strength of the rear bushing. The first rubber sleeve 1 and the second rubber sleeve 2 are both made of natural rubber NR. NR natural rubber is a natural polymer compound with cis-1,4-polyisoprene as the main component, 91% to 94% of which is rubber hydrocarbon cis-1,4-polyisoprene, and the rest is non-rubber substances such as protein, fatty acid, ash, and sugar.

[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
