The rear side of the rear axle stabilizer bar 1 is provided with a mounting support 201, and the mounting The front end of the support 201 is fixedly connected with a first bushing 2011, and the outer side of the first bushing 2011 is provided with a second bushing 202. An oil filling hole 2021 is provided in the middle of the second bushing 202, and an oil passage 2022 is provided on the inner side walls of the first bushing 2011 and the second bushing 202. At the same time, connecting support plates 2023 are fixedly connected to both ends of the second bushing 202, and an inserting wedge block 2024 is fixedly connected to the end of the connecting support plate 2023, and a locking wedge groove 2025 is provided on the inserting wedge block 2024. The mounting bracket 201 is provided with a plug-in square groove 203, and a locking wedge 2042 is provided inside the plug-in square groove 203. The locking wedge 2042 is clamped in the locking wedge groove 2025. The first bushing 2011 is sleeved on one side of the rear axle stabilizer bar 1, and then the plug-in wedge 2024 on the second bushing 202 is inserted into the plug-in square groove 203. At this time, the plug-in wedge 2024 will squeeze the locking wedge 2042 into the active cavity 2043 under the action of the inclined surface. When the locking wedge 2042 cannot be blocked by the plug-in wedge 2024, the locking wedge 2042 will be locked. When squeezed, the locking wedge block 2042 is reset under the action of the spring so that it is stuck in the locking wedge groove 2025. The locking wedge block 2042 and the locking wedge groove 2025 make the bushing and the stabilizer bar fit tightly, so that the bushing and the rear axle stabilizer bar 1 can be quickly installed, and it is convenient for maintenance personnel to disassemble and replace the bushing, which is convenient for later maintenance.

[0034] The specific usage and function of this embodiment are as follows:

[0035] In the present invention, firstly, the first bushing 2011 is sleeved on one side of the rear axle stabilizer bar 1, and then the plug-in wedge 2024 on the second bushing 202 is inserted into the plug-in square groove 203. At this time, the plug-in wedge 2024 will squeeze the locking wedge 2042 into the active cavity 2043 under the action of the inclined surface, and the locking wedge 2042 drives the connecting pillar 2041 to move upward, and the connecting pillar 2041 drives the extrusion convex ring 2044 to squeeze the reset spring 2046 in the reset column groove 2045. When the locking wedge 2042 is not squeezed by the plug-in wedge 2024, the reset spring 20 46 loses the extrusion pressure, and then releases the elasticity. Under the action of the elastic force, the extrusion convex ring 2044 is pushed to move, and the extrusion convex ring 2044 drives the connecting pillar 2041 to move. The connecting pillar 2041 drives the locking wedge block 2042 to reset so that it is stuck in the locking wedge groove 2025, thereby completing the quick installation of the bushing and the rear axle stabilizer bar 1. When removing the bushing, it is only necessary to pull the handle 2047 to drive the connecting pillar 2041 to move, so that the connecting pillar 2041 drives the locking wedge block 2042 to disengage from the locking wedge groove 2025 and move into the movable cavity 2043, and then the bushing can be removed for replacement.
