Technical Field

[0001] The utility model relates to the technical field of automobile bushings, in particular to an anti-falling automobile bushing. Background Art

[0002] As a key component in the vehicle suspension system, the existing automobile bushing mainly plays the role of shock absorption, noise reduction and impact buffering. However, the automobile bushing in the prior art often faces the following shortcomings during use:

[0003] 1. Poor buffering effect: Most existing bushings only rely on the rubber buffer layer in the middle to achieve the buffering effect, and the buffering performance is poor, resulting in the inability to effectively alleviate the impact of the road during vehicle driving, thus affecting the ride comfort;

[0004] 2. Aging and cracking of the buffer layer: Existing bushings usually have a buffer layer between the outer ring and the inner ring. These buffer layers are mostly made of rubber or other elastic materials. However, with the extension of usage time, the buffer layer is prone to aging and cracking under repeated compression and stretching, which will not only lead to a significant decrease in the buffering effect of the bushing, but also affect the stability of its overall structure, causing the vehicle to generate more vibration and noise during driving.

[0025] In addition, a buffer area is provided between the outer ring 100 and the inner ring 200, and a plurality of groups of elastic members 300 are fixedly connected to the inner wall of the outer ring 100, and the other end of each group of elastic members 300 is fixedly connected to the outer wall of the inner ring 200. A buffer layer 400 is provided in the buffer area, and the end of the buffer layer 400 is located in the area between the end of the inner ring 200 and the end of the outer ring 100, and the elastic member 300 is buried in the buffer layer 400. Moreover, the buffer layer 400 is a rubber layer, and the rubber layer here is filled in the buffer area by injection molding.
