Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of automotive chassis suspension system components, specifically referring to an adjustable eccentric rubber bushing for automotive chassis. Background Technology
[0002] During vehicle operation, the accuracy of geometric parameters such as wheel camber and toe angle directly affects driving stability and tire life. Existing chassis bushings are mostly concentric structures, serving only a connecting and cushioning function, and cannot adjust wheel angles. When problems such as uneven tire wear or vehicle pulling to one side occur due to angular deviations, corrections must be made through complex methods such as adding shims or replacing control arms, which is cumbersome and costly. Utility Model Content
[0003] The present invention aims to provide an eccentric chassis bushing structure that does not require additional adjustment components. It achieves wheel geometry correction through its own structural characteristics, thereby solving the problems of uneven tire wear and vehicle instability.
[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: The present utility model proposes an adjustable eccentric rubber bushing for automobile chassis, including an integrally formed cylindrical outer shell, an elastic body is provided inside the outer shell, an inner shell is provided through the axis of the elastic body, and the length of the inner shell is greater than the length of the outer shell, an installation hole for inserting the inner bushing is provided in the middle of the inner shell, the inner bushing rotates on the inner shell, and the axis of the inner bushing is eccentrically set with respect to the geometric center of the outer shell.
[0005] Furthermore, the outer circumferential surface of the inner bushing is interference-fitted with the inner circumferential surface of the inner shell.
[0006] Furthermore, the elastomer is made of rubber.
[0007] The beneficial effects of this utility model by adopting the above structure are as follows:
[0008] 1. No additional structural adjustments required: Angle adjustment is achieved through the eccentric design of the elastomer and the inner bushing, avoiding the addition of complex adjustment parts and maintaining a simple structure;
[0009] 2. Easy installation: Angle correction can be completed simply by replacing the traditional rubber sleeve, without the need for professional modification tools;
[0010] 3. Low cost: Compared to replacing the swing arm or adding an adjustment device, the problem can be solved simply by using the eccentric design of the rubber sleeve, which significantly reduces maintenance costs;
[0011] 4. Dual function: It retains the cushioning and vibration reduction function of traditional rubber bushings, and also has an angle adjustment function to improve vehicle driving stability and reduce tire wear. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0016] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0017] Example 1:
[0018] As per the instruction manual Figure 1-2 As shown, an adjustable eccentric rubber bushing for an automobile chassis includes an integrally formed cylindrical outer shell 1. An elastomer 2 is disposed inside the outer shell 1. The elastomer 2 is made of rubber. An inner shell 3 is disposed through the axis of the elastomer 2, and the length of the inner shell 3 is greater than the length of the outer shell 1. An installation hole 5 for inserting an inner bushing 4 is provided in the middle of the inner shell 3. The inner bushing 4 rotates on the inner shell 3, and the axis of the inner bushing 4 is eccentrically set with respect to the geometric center of the outer shell 1. Through the cooperation of this eccentric structure with the automobile swing arm, the installation position of the swing arm can be changed, thereby driving the wheel to achieve changes in geometric angles such as wheel camber angle or toe angle, so as to solve the problems of uneven tire wear and vehicle instability. The outer peripheral surface of the inner bushing 4 is interference-fitted with the inner peripheral surface of the inner shell 3.
[0019] In practical implementation, the product of this invention is installed at the connection position between the car swing arm and the chassis. Due to the eccentric design of the inner bushing 4, the swing arm will have a slight offset relative to the original installation position. This offset is transmitted to the wheel through the swing arm, causing the wheel camber angle or toe angle to be adjusted accordingly. Depending on the degree of vehicle angle deviation, inner bushings 4 with different eccentric distances can be selected for adaptation and installation to ensure that the wheel geometry parameters meet the standard values. The rubber elastomer 2 can effectively buffer road vibration while realizing angle adjustment, ensuring driving comfort.
[0020] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
[0021] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
