Description

Technical Field

[0001] This utility model belongs to the field of automotive parts technology, specifically an automotive suspension bushing. Background Technology

[0002] A bushing is an accessory used on the outside of mechanical parts to achieve functions such as sealing and wear protection; it refers to a ring that acts as a gasket. In valve applications, bushings are placed inside the valve cover and are generally made of corrosion-resistant materials such as polytetrafluoroethylene (PTFE) or graphite for sealing purposes. In automotive suspensions, bushings are typically installed to protect the suspension.

[0003] For example, in the automotive suspension bushing assembly disclosed in CN216407583U, the bushing uses a rubber body in conjunction with a coil spring to prevent the rubber body from tearing. However, the coil spring itself is unstable and will generate a certain torque on the rubber body when it is not working, so its effect on preventing tearing is relatively limited. In order to solve the above problems, an automotive suspension bushing is proposed. Utility Model Content

[0004] The purpose of this utility model is to provide an automotive suspension bushing in order to solve the above-mentioned problems.

[0005] The technical solution adopted by this utility model is as follows: A car suspension bushing, comprising:

[0006] The outer shell has a ring-shaped structure;

[0007] A rubber body is fixedly installed on the inner wall of the outer shell, and an oil groove is provided inside the rubber body, and hydraulic oil is provided inside the oil groove;

[0008] The central shaft is fixedly installed inside the rubber body.

[0009] With the above technical solution, when in use, the bushing is installed in the sleeve of the suspension arm. When the sleeve is subjected to the torque generated by the suspension, the rubber body inside the outer shell deforms under the influence of the torque. During the deformation process, because it is equipped with an oil groove and hydraulic oil is installed inside the oil groove, the hydraulic oil distributes part of the torque, thereby effectively improving the service life of the bushing.

[0010] In a preferred embodiment, a metal sheet is fixedly mounted on the outer wall of the rubber body.

[0011] The above technical solution improves the overall strength of the rubber body by using metal sheets.

[0012] In a preferred embodiment, the outer wall of the rubber body is provided with a prestressed groove.

[0013] By using the above technical solution, a prestressed groove is opened on the outer wall of the rubber body. When the rubber body is deformed by external torque, the prestressed groove provides deformation space, which can effectively prevent the bushing from tearing.

[0014] In a preferred embodiment, a boss is integrally provided in the center of the central shaft.

[0015] By using the above technical solution, a boss is set in the middle of the central shaft to increase the contact area between the central shaft and the rubber body, thereby improving the firmness between the two.

[0016] In a preferred embodiment, the rubber body is manufactured and molded from polyurethane.

[0017] In summary, due to the adoption of the above technical solution, the beneficial effect of this utility model is: this utility model proposes an automotive suspension bushing.

[0018] 1. When in use, install this bushing inside the sleeve of the suspension arm. When the sleeve is subjected to the torque generated by the suspension, the rubber body inside the outer shell deforms under the influence of the torque. During the deformation process, because it is equipped with an oil groove and contains hydraulic oil, the hydraulic oil distributes part of the torque, thereby effectively improving the service life of the bushing.

[0019] 2. By opening prestressed grooves on the outer wall of the rubber body, when the rubber body is deformed by external torque, the prestressed grooves provide deformation space, which can effectively prevent the bushing from tearing. Attached Figure Description

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below in conjunction with the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] The following will combine Figure 1-2A detailed description of an automotive suspension bushing according to an embodiment of the present invention will be provided.

[0025] Example:

[0026] An automotive suspension bushing, comprising:

[0027] The outer shell 1 has a circular ring structure;

[0028] Rubber body 2 is fixedly installed on the inner wall of outer shell 1. Rubber body 2 is made of polyurethane. A prestressed groove 22 is provided on the outer wall of rubber body 2. By providing a deformation space through the prestressed groove 22 on the outer wall of rubber body 2 when rubber body 2 is deformed by external torque, the bushing can be effectively prevented from tearing.

[0029] The rubber body 2 has an oil groove 23 inside, and hydraulic oil is installed inside the oil groove 23. A metal sheet 21 is fixedly installed on the outer wall of the rubber body 2. The overall strength of the rubber body 2 is improved by the metal sheet 21. In use, this bushing is installed in the sleeve of the suspension arm. When the sleeve is subjected to the torque generated by the suspension, the rubber body 2 inside the outer shell 1 deforms under the influence of the torque. During the deformation process, because it has an oil groove 23 inside, and the oil groove 23 is filled with hydraulic oil, part of the torque is distributed by the hydraulic oil, thereby effectively improving the service life of the bushing.

[0030] The central shaft 3 is fixedly installed inside the rubber body 2. A boss 31 is integrally provided in the middle of the central shaft 3. By providing the boss 31 in the middle of the central shaft 3, the contact area between the central shaft 3 and the rubber body 2 is increased, thereby improving the firmness between the two.

[0031] Working principle:

[0032] In use, this bushing is installed inside the sleeve of the suspension arm. When the sleeve is subjected to the torque generated by the suspension, the rubber body 2 inside the outer shell 1 deforms under the influence of the torque. During the deformation process, since there is an oil groove 23 inside, and the oil groove 23 is filled with hydraulic oil, part of the torque is distributed by the hydraulic oil, which can effectively improve the service life of the bushing. By opening a prestress groove 22 on the outer wall of the rubber body 2, when the rubber body 2 is subjected to external torque and deforms, the prestress groove 22 provides deformation space, which can effectively prevent the bushing from tearing.

[0033] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
