[0030] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0031] Reference Figure 1-4The anti-aging automobile upper support bushing comprises: an outer sleeve 100 and an inner sleeve 101, a buffer rubber 102, a buffer ring 103, a retaining ring 104, and an abutting ring 105. The outer sleeve 100 is sleeved on the inner sleeve 101, and the buffer rubber 102 is located between the inner sleeve 101 and the outer sleeve 100. The retaining ring 104 is arranged at both ends of the outer sleeve 100, and a threaded circular groove 106 concentric with the outer sleeve 100 is opened at both ends of the outer sleeve 100. The outer wall of the retaining ring 104 is provided with a thread, and the retaining ring 104 is threadedly installed in the threaded circular groove 106. Four groups of through holes 107 are opened on the retaining ring 104, and four groups of mounting holes 108 coinciding with the through holes 107 are opened at both ends of the outer sleeve 100. The screws pass through the through holes 107 and are threadedly connected with the mounting holes 108 to install the retaining ring 104.

[0032] A flange 109 is fixedly provided on the inner sleeve 101, and the outer diameter of the flange 109 is smaller than the inner diameter of the outer sleeve 100 and larger than the inner diameter of the retaining ring 104, so that the inner sleeve 101 can be radially displaced relative to the outer sleeve 100. Two abutment rings 105 are provided, which are slidably provided in the outer sleeve 100, and the two abutment rings 105 are respectively located between the flange 109 and the retaining ring 104, and the inner diameter of the abutment ring 105 is larger than the outer diameter of the inner sleeve 101, and the outer diameter of the abutment ring 105 is smaller than the inner diameter of the outer sleeve 100, so that the radial displacement of the outer sleeve 100 can be radially displaced relative to the outer sleeve 100. The retaining ring 104 is provided with two groups of threaded holes 110 distributed circumferentially, and the threaded holes 110 are threadedly connected with bolts 111, and one end of the bolts 111 abuts against the abutment ring 105. The buffer ring 103 is disposed between the abutment ring 105 and the flange 109 , and the axial movement of the inner sleeve 101 and the outer sleeve 100 is buffered by the buffer ring 103 .

[0033] Two limiting rings 112 are slidably provided on the inner sleeve 101. The outer diameter of the limiting rings 112 is smaller than the outer diameter of the flange 109. The two ends of the buffer rubber 102 abut against the two limiting rings 112 respectively. A guide groove 113 extending in the axial direction is provided on the outer wall of the inner sleeve 101. A protrusion 114 embedded in the guide groove 113 is provided on the limiting ring 112. A bidirectional screw 115 having one end inserted into the guide groove 113 and extending along the guide groove 113 is rotatably connected to the flange 109. The bidirectional screw 115 passes through the protrusion 114 and is threadedly connected to the protrusion 114. By rotating the bidirectional screw 115, the two limiting rings 112 move away from or towards each other, and the buffer rubber 102 is limited in the axial direction.

[0034] An axially extending positioning groove 116 is provided on the outer wall of the inner sleeve 101, and a positioning protrusion 117 is provided on the buffer rubber 102 and is embedded in the positioning groove 116. A circumferentially extending limiting protrusion 118 is provided on the inner side of the outer sleeve 100, and a limiting groove 119 is provided on the buffer rubber 102 for the limiting protrusion 118 to be embedded. The buffer rubber 102 is limited by the positioning groove 116 and the limiting protrusion 118 to prevent the buffer rubber 102 from rotating or axially moving.

[0035] Working or installation process: By removing the retaining ring 104, it is convenient to install the inner sleeve 101, the buffer rubber 102 and the buffer ring 103. When the outer sleeve 100 and the inner sleeve 101 need to be buffered axially, by rotating the bolt 111, one end of the bolt 111 abuts against the abutment ring 105, thereby squeezing the buffer ring 103, so that the buffer ring 103 abuts against the abutment ring 105 and the flange 109, the axial buffering of the inner sleeve 101 and the outer sleeve 100 is performed. By rotating the bidirectional screw 115, the two limiting rings 112 move away from or towards each other, and the buffer rubber 102 is limited in the axial direction. The buffer rubber 102 is limited by the positioning groove 116 and the limiting protrusion 118 to prevent the buffer rubber 102 from rotating or moving axially.
