In the present exemplary embodiment, the pressurization mechanism includes a first pressurization cavity 3 and a second pressurization cavity 31, the first pressurization cavity 3 and the second pressurization cavity 31 are both of a semi-annular design, the first pressurization cavity 3 and the second pressurization cavity 31 are respectively opened at two sides of the cushion ring 21, and the arrangement order of the first pressurization cavity 3 and the second pressurization cavity 31 is parallel to the length of the road;
an expansion cavity 32, wherein the expansion cavity 32 is opened inside the backing ring 24, and the expansion cavity 32 is respectively communicated with the first pressurizing cavity 3 and the second pressurizing cavity 31;

after the cover plate 11 and the base 1 are fixed by the locking plate 22 and the locking hole 23, in the long-time use process, the cover plate 11 and the base 1 are in a stable connection state, and no relative displacement is generated between the cover plate 11 and the base 1, so that no impact and noise are generated under the action of an automobile, but after abrasion and looseness are generated between the base 1 and the cover plate 11 due to the pressure action, after the automobile and the like run on the cover plate 11, under the action of pressure, the cover plate 11 has a tendency of moving towards the direction of the bearing ring 2, when the cover plate 11 moves towards the direction of the bearing ring 2, the piston rod 41 with the top end extending to the lower surface of the cover plate 11 is firstly under the action of pressure, the piston rod 41 moves towards the interior of the compression cylinder 4, and because one end of the piston rod 41 located in the compression cylinder 4 is sleeved with a rubber pad and a ring, so that the piston rod 41 is connected with the compression cylinder 4 in a sliding and sealing manner, in the process that the piston rod 41 extrudes towards the inside of the compression cylinder 4, air inside the compression cylinder 4 is compressed, so that the air pressure is increased, the air has the tendency of moving from the compression cylinder 4 to the one-way air outlet pipe 43 under the action of the pressure, passes through the one-way air outlet pipe 43 and respectively enters the first pressurizing cavity 3 and the second pressurizing cavity 31 and then enters the expansion cavity 32, under the filling action of the air, the pressure in the first pressurizing cavity 3, the second pressurizing cavity 31 and the expansion cavity 32 is increased, so that the cushion ring 21 and the cushion ring 24 are deformed by utilizing the air pressure, the deformed cushion ring 24 and the cushion ring 21 compensate abrasion between the cover plate 11 and the base 1, and support the cover plate 11 under the action of the internal pressure, so as to effectively reduce the displacement of the cover plate 11 under the action of the automobile pressure, thereby effectively reducing the continuous abrasion rate of the cover plate 11 and the base 1, effectively prolonging the service life of the cover plate 11 and the base 1,
