Referring to fig. 1 to 4, the present embodiment provides a suspension bushing, including: the inner mounting bracket 10 is used for being connected with a vehicle body, an inner bushing 20 is sleeved on the inner mounting bracket 10, an inner steel pipe 30 is sleeved outside the inner bushing 20, an outer bushing 40 is sleeved outside the inner steel pipe 30, and an outer steel pipe 50 is sleeved outside the outer bushing 40; the inner mounting bracket 10 is provided with a restricting portion 10a, the inner steel pipe 30 is provided with an engaging portion 30a, the engaging portion 30a is slidable with respect to the inner mounting bracket 10, and the restricting portion 10a restricts the sliding of the engaging portion 30 a.
Specifically, the inner liner 20, the inner steel pipe 30, the outer liner 40, and the outer steel pipe 50 are all cylindrical and are disposed coaxially with the inner mounting bracket 10. The inner bushing 20 and the outer bushing 40 are coupled with each other, and the rigidity of the suspension bushing can be adjusted by adjusting the thickness and rigidity of the inner bushing 20 and the outer bushing 40; the inner and outer liners 20, 40 may be made of rubber; the rubber is a high-elasticity polymer material with reversible deformation, is rich in elasticity at room temperature, can generate deformation under the action of external force, and can recover the original shape after the external force is removed; the molecular chain of the rubber can be crosslinked, and the crosslinked rubber has the capability of rapid recovery when deformed under the action of external force, and has good physical and mechanical properties and chemical stability.
In this embodiment, the engaging portion 30a may be a groove or a long hole, and the like, the groove or the long hole includes a sliding space for providing a space for the sliding of the regulating portion 10a and a side wall for regulating the sliding of the regulating portion 10 a; the restriction portion 10a may be a protrusion extending into a sliding space of the groove or the long hole, and at this time, the groove or the long hole can slide with respect to the protrusion, and restrict the rotation of the inner steel pipe 30 when at least two adjacent sidewalls of the groove or the long hole abut against the protrusion. Taking the engaging portion 30a as a groove, the groove is rectangular: when the protrusions contact with two adjacent side walls, the engaging portion 30a abuts against the limiting portion 10a, and at this time, the engaging portion 30a cannot slide continuously under the limiting action of the limiting portion 10 a.
Wherein, in the process that the clamping part 30a slides relative to the limiting part 10a, the inner steel pipe 30 rotates relative to the inner mounting bracket 10, and at the moment, the inner bushing 20 generates torsional deformation; when the inner bushing 20 is twisted to a certain degree relative to the inner mounting bracket 10, that is, when the inner steel pipe 30 rotates to a certain angle relative to the inner mounting bracket 10, the limiting portion 10a abuts against the engaging portion 30a, at this time, the limiting portion 10a limits the sliding of the engaging portion 30a, that is, limits the rotation of the inner steel pipe 30, the inner steel pipe 30 is rigidly connected to the inner mounting bracket 10, the inner bushing 20 is not deformed, only the outer bushing 40 plays a role in damping and buffering, and the rigidity of the suspension bushing is significantly increased.

The vulcanization is a process of a crosslinking reaction of the rubber under certain pressure, temperature and time conditions. The vulcanization process is mainly used for improving the performance of rubber products, and is a process for physically converting plastic rubber into elastic rubber or hard rubber. No crosslinking between molecules occurs before the rubber is unvulcanized. After the rubber is added with the vulcanizing agent, the rubber molecules can be crosslinked through heat treatment or other modes to form a three-dimensional network structure, so that the performance of the rubber is greatly improved. An adhesive is applied to the outer surface of the inner mounting bracket 10 before vulcanization. During vulcanization molding, the adhesive and the rubber are subjected to vulcanization crosslinking reaction, so that the rubber and the adhesive are tightly connected together, the rubber and the outer surface of the inner mounting bracket 10 are well bonded, and vulcanization bonding is realized.
