Description

Technical Field

[0001] The utility model particularly relates to a stabilizer bar bushing assembled in a small space. 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-cylinder-shaped with a relatively simple structure. It is difficult to meet the requirements of good stiffness performance in a small space. For this reason, we propose a stabilizer bar bushing based on small space assembly. Utility Model Content

[0003] The utility model aims to provide a stabilizer bar bushing based on small space assembly to solve the problems raised in the above background technology.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a stabilizer bar bushing based on small space assembly, comprising:

[0005] A first rubber sleeve and a second rubber sleeve arranged side by side with the first rubber sleeve, wherein the second rubber sleeve and the first rubber sleeve are both embedded with a special-shaped frame inside, and the special-shaped frame is connected end to end with another special-shaped frame to form an annular bushing;

[0006] Wherein, a protrusion is integrally formed on the second rubber sleeve.

[0007] Preferably, the special-shaped frame includes a first supporting portion, a second supporting portion and a connecting rib block, both ends of the first supporting portion are recessed inward to form two second supporting portions, and the connecting rib block is fixed to an end surface of one of the second supporting portions.

[0008] Preferably, the first supporting portion is semi-annular, and two first supporting portions are provided.

[0009] Preferably, a through hole is opened inside the first supporting portion, and a plurality of the through holes are evenly distributed along the circumference of the first supporting portion.

[0010] Preferably, the first rubber sleeve is made of plastic.

[0011] Preferably, the second rubber sleeve is made of NR natural rubber.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] This patent uses the second support part and the first support part 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 skeleton design, which is convenient for application and installation on stabilizer bars of various models in small spaces. The through hole facilitates the good connection and fixation of the second rubber sleeve and the first support part during production. The design of two special-shaped skeletons facilitates segmented production and final assembly to prevent the inconvenience of upper skeleton and product demoulding during production.

[0019] 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.

[0020] See also Figure 1-Figure 4 The utility model provides a technical solution: a stabilizer bar bushing based on small space assembly, comprising:

[0021] The first rubber sleeve 1 and the second rubber sleeve 2 arranged side by side with the first rubber sleeve 1, and the second rubber sleeve 2 and the first rubber sleeve 1 are both embedded with a special-shaped frame 4 inside, 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, and the special-shaped frame 4 is connected end to end with another special-shaped frame 4 to form an annular bushing, which is convenient for assembly and segmented production compared with the traditional stabilizer bar bushing structure. In actual production, the thickness of the main force-bearing area of ​​the special-shaped frame 4 made of plastic material changes with the change of the stabilizer bar wire diameter;

[0022] The second rubber sleeve 2 is integrally formed with a protrusion 3 to provide better rigidity requirements.

[0023] In this embodiment, preferably, the special-shaped skeleton 4 includes a first support portion 41, a second support portion 42 and a connecting rib block 43. The two ends of the first support portion 41 are recessed inward to form two second support portions 42, which is convenient for increasing the contact area with the external clamp and stabilizer rod, so as to better distribute the force evenly to provide better stiffness effect. The connecting rib block 43 is fixed to one end face of one of the second support portions 42, which is convenient for segmented production and then fixed by the connecting rib block 43.

[0024] In this embodiment, preferably, the first support portion 41 is semi-annular, and two first support portions 41 are provided to facilitate connection and fixed assembly to form an annular bushing.

[0025] In this embodiment, preferably, a through hole 411 is opened on the inner side of the first support portion 41, and multiple through holes 411 are evenly distributed along the circumference of the first support portion 41, which is convenient for production and ensures that the rubber can flow smoothly during the production process, so that the second rubber sleeve 2 can be better connected and fixed to the special-shaped frame 4.

[0026] In this embodiment, preferably, the first rubber sleeve 1 is made of plastic, and the plastic is composed of PA66 and GF35, so as to enhance the strength of the rear bushing.

[0027] In this embodiment, preferably, the second rubber sleeve 2 is made of NR natural rubber. NR natural rubber is a natural polymer compound with cis-1,4-polyisoprene as the main component, 91% to 94% of its components are rubber hydrocarbons (cis-1,4-polyisoprene), and the rest are non-rubber substances such as proteins, fatty acids, ash, and sugars.

[0028] 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.
