[0022] The embodiments of the present application will be described in detail below, and examples of the embodiments are represented in the drawings, wherein the same or similar symbols represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present application, and cannot be understood as a limitation on the present application.
[0023] Example 1
[0024] Reference Figs. 1 to 4 The combined support shock-absorbing sleeve described in the present embodiment includes a male end bushing 3 and a female end bushing 4, the male end bushing 3 is divided into a buffer end 31 and an insertion end 32, the diameter of the buffer end 31 is greater than the diameter of the insertion end 32 and the mounting hole 11 of the support 1, the bottom end of the buffer end 31 is in contact with the top end of the support 1, the buffer end 31 and the insertion end 32 are provided with an inner hole 33 along the axial direction, the insertion end 32 is inserted into the insertion hole 41 of the female end bushing 4 through the mounting hole 11, a pipe sleeve 2 is inserted into the inner hole 33, the pipe sleeve 2 is T-shaped, the outer wall of the pipe end of the pipe sleeve 2 is tightly attached to the inner wall of the inner hole 33, and the pipe end of the pipe sleeve 2 is not shorter than the height of the male end bushing 3.
[0025] Preferably, the buffer end 31 and the female end bushing 4 away from the support 1 are petal-shaped, and the inner wall of the inner hole 33 is also petal-shaped. The petal-shaped male end bushing 3 and the female end bushing 4 are used to reduce the rigidity, and the petal-shaped inner hole 33 reduces the rigidity of the male end bushing 3 while making the sleeve 2 and the inner hole 33 close when being extruded.
[0026] Preferably, a plurality of auxiliary holes 6 are arranged on the buffer end 31, and a plurality of auxiliary holes 6 are arranged on the end of the female end bushing 4 away from the support 1. The auxiliary holes 6 are used to reduce the rigidity of the male end bushing 3 and the female end bushing 4.
[0027] When the support 1 is thicker, the sleeve 2 and the insertion end 32 cannot reach the bottom end of the insertion hole 41, so the gasket 5 can be pressed into the insertion hole 41 and the gasket 5 is in contact with the bottom end of the sleeve 2.
[0028] The inner diameter of the gasket 5 is not greater than the inner diameter of the sleeve 2, and preferably the inner diameter of the gasket 5 is equal to the inner diameter of the sleeve 4.
[0029] The bolt is inserted into the sleeve 2 and the gasket 5 is installed on the body of the support 1. The sleeve 2 and the gasket 5 facilitate the installation of the bolt and prevent damage to the male end bushing 3 and the female end bushing 4.
[0030] The sleeve 2 and the gasket 5 are made of plastic material, and preferably the sleeve 2 and the gasket 5 are made of metal material.
[0031] The male end bushing 3 and the female end bushing 4 are made of elastic material, and preferably the male end bushing 3 and the female end bushing 4 are made of rubber material.
[0032] The insertion end 32 of the male end bushing 3 is inserted into the mounting hole 11 of the support 1, and then the insertion hole 41 of the female end bushing 4 is sleeved on the insertion end 32, so as to be fixed on the support 1. Since the male end bushing 3 and the female end bushing 4 are separated, they can match supports 1 of various thicknesses. At present, the thickness of the support 1 on the market is mostly 2mm-4mm. When the support 1 is thicker, the sleeve 2 cannot be inserted into the bottom end of the insertion hole 41. At this time, the gasket 5 can make up for the difference, so that the male end bushing 3 and the female end bushing 4 are assembled more fixedly.
[0033] The male end bush 3 and the female end bush 4 of multiple rigidities are respectively produced by using the same set of molds. In the NVH performance tuning process, due to consideration of product and vehicle system matching, the same product may have different NVH performances on different vehicle models. At this time, the NVH performance can be tuned by adjusting the rigidity of the related damping system. At this time, the male end bush 3 and the female end bush 4 of different rigidities can be matched to complete the tuning. For example, the rubber hardness of the male end bush 3 is changed from ShA40 to ShA70. In this way, seven kinds of male end bushes 3 of different rigidities can be obtained without changing the mold. The rubber hardness of the female end bush 4 is changed from ShA40 to ShA70. In this way, seven kinds of female end bushes 4 of different rigidities can be obtained without changing the mold. In this way, 49 kinds of hardness combinations can be obtained, so that the NVH performance is more convenient and fast during tuning, and the applicability of the combined secondary damping is wider, and the cost is lower.
