In an automobile suspension system, a lining assembly is a flexible element and plays a role in buffering and shock absorption in the running process of an automobile, and it can be seen that the higher the rigidity of the lining assembly is, the more the controllability of the overall performance of the automobile is, and conversely, the more comfortable the overall performance of the automobile is. The stiffness of a bushing assembly in an existing automotive suspension system is determined at the beginning of the design, and therefore, once the bushing assembly is structurally and materially determined during the design process, it is possible to substantially determine whether the vehicle in which it is used is handling or comfort-prone. As can be seen from fig. 1 and 2, the bushing assembly of the present invention is provided with an inner tube 1 and an outer tube 4, a middle tube is further sleeved between the inner tube 1 and the outer tube 4, gaps are formed between the inner tube 1, the middle tube and the outer tube 4, the inner tube 1, the middle tube and the outer tube 4 form concentric circles, a buffer member 5 is connected in each gap, the inner tube 1, the middle tube and the outer tube 4 can ensure the rigidity requirement of the bushing assembly, and the buffer member 5 ensures the flexibility requirement of the bushing assembly, and mainly can play a role in shock absorption.
As a preferred embodiment, the middle tube sequentially comprises a first middle tube 2 and a second middle tube 3 from inside to outside, the first middle tube 2 is provided with a first middle tube locking hole 201, the second middle tube 3 is provided with a second middle tube locking hole 301, and the first middle tube locking hole 201 and the second middle tube locking hole 301 are correspondingly arranged.

The buffering members 5 between the inner pipe 1 and the first middle pipe 2 are distributed in a quartering manner around the central axis, the buffering members 5 between the pipes are distributed along the radius to form radial groups 501, the quartering radial groups 501 are formed into a cross shape, or trisection radial groups 501, or five equi-distribution radial groups 501, or other equi-distribution radial groups 501, the main purpose of the device is to ensure the rigidity of the inner pipe 1, each middle pipe and the outer pipe 4, and meanwhile, the radial groups 501 formed by the buffering members 5 can adjust the rigidity, so that a symmetrical structural form is generally formed, and the device is convenient to control the change of force accurately and conveniently.
Further, the buffer member 5 is a rubber buffer member, and the buffer member 5 is connected with the inner tube 1, the middle tubes and the outer tube 4 in a vulcanization manner. The vulcanization is also called as cross-linking and curing, after vulcanization, the physical and mechanical properties of the rubber are obviously improved, the strength, elasticity and tensile modulus are increased, and the plastic deformation is reduced, so that the rubber becomes an insoluble elastomer. Therefore, after the buffer piece 5 is vulcanized and connected with the inner pipe 1, each middle pipe and the outer pipe 4, the joint part has higher strength, and the joint part is smoother, so that the overall appearance effect of the bushing assembly can be improved, and the overall rigidity of the bushing assembly can also be improved.
